September 2014 Summary This Code was developed in the context of contemporary State forest management in Queensland. The Parties The Queensland Parks and Wildl ife Service (QPWS), a division of the Department of National Parks, Recreation, Sports and Racing (DNPRSR), is the custodian of the QPWS forest estate (State forests and timber reserves). Forest Products, a business unit w ithin the Queensland Department of Agriculture Fisheries and Forestry (DAFF Forest Products), is responsible for commerc ial harvesting and the sale of the State's native forest timber resources . Background The Code of Practice for Native Forest Timber Production on the QPWS Forest Estate 2014 (the Code) prescribes environmental management standards for timber harvesting on the QPWS forest estate. This Code addresses the harvesting of timber products such as sawlogs, poles , piles , girders, sandalwood , landscaping, fencing timbers and other timbe r products. The Code is a key element in implementing ecologically sustainable forest management (ESFM) across the QPWS forest estate in accordance with relevant nationa l and State policy for native forests . The Code has been developed through a process of review and consultation with government, industry and community groups and technical specialists . The Code is focused on prescribing operational standards to achieve a high level of protection of environmenta l values (including endangered species , their habitat, water quality, soil properties, and ecological processes). Code Linkages The Code also establ ishes links with the National Forest Policy Statement 1992 (NFPS) and various State government forest policy outcomes , environmenta l commitments and planning instruments. The Code addresses regional ecosystem (RE ) management, threatened species management and cultural heritage management. The maintenance of a native forest structure and ecosystem function following harvesting, as promoted by the Code, contributes to the maintenance of water, carbon and other nutrient cycles through the abil ity of native forests to natural ly regenerate and through the long term storage of carbon provided by forests and by timber products. iii CONTENTS Summary .... .......... ......... ........................... ....... ........ ......... ... ......... .............................. .......... .... ....... .......... .... iii The Parties ............ .... ... ... ... .............. ... ..... ....... .......... ..... ........ .......... ...... .... ..... ...... ......... ... ... ... ..... ... ... ... ... iii Background ... ... ... ... ... ... ...... .... ....... .. .... ..... ........ ..... ... ...... ..... ... ......... ....... .. .. ... ... .... ..... ........ ... ......... ..... ... ... iii Code Linkages ...... ....... ..... ................ ...... .... ................. ... ........ ...... ... ... .. ... ... .... ............. ........ ... iii 1.

Introduction Defining the Code's purpose, application and management responsibilities 1.1 Background The Forestry Act 1959 provides for the reservation , management, silvicultura l treatment and protection of State forests and the sale of forest products on State lands, including the QPWS forest estate's State forests and timber reserves. On State forests , the cardinal principle of management is the permanent reservation of areas for the purpose of providing timber and associated products in perpetuity and protecting a watershed therein , having due regard to: conservation of the soi l and the environment; benefits of permitted grazing ; and the possibil ity of applying the area to recreational purposes . The State's forests are managed for multiple use accord ing to the principles of ecologically sustainable forest management (ESFM) consistent with the NFPS. Multiple use management is the management of diverse forest uses and values. It covers timber and other forest products, as wel l as conservation of the forest environment, water catchment and soil protection , wildl ife habitat, landscape, wilderness, genetic resources and diversity, recreation , scientific study and education. Such management must be dynamic and does not necessari ly imply fixed priorities of use on any particular area nor, that any particular areas must simultaneously provide all products and values at all times. Maintenance of these uses and values requires that forest management is consistent with the principles of ESFM. ESFM must be applied to all aspects of timber production and al l tenures to: • mainta in, or where necessary, enhance ecological and evolutionary processes within forests ; mainta in, or where necessary, enhance the biological diversity of forests, from species to landscapes; and • optimise the net social, economic and cultural heritage benefits derived from a mixture of forest uses, within ecological constraints , while maintaining options for the future use. Guiding principles for ESFM are: 1 the maintenance, protection or, where appropriate, the enhancement of biodiversity, productive capacity, sustainability and health of forest ecosystems, soi l and water resources, forest contribution to global carbon cycles , long term, social and economic benefits, and natural and cultural heritage values. The enhancement of biodiversity may be achieved through appropriate planning strategies. 2 where appropriate, apply the precautionary principle for the prevention of environmental degradation. 3 prevention or mitigation of impacts , on-site an~ off-s ite, of forest management practices, which are , or may be deleterious. 4 protect Indigenous cultural heritage and ensure participation of Indigenous peoples in all aspects of forested land management and planning . The N FPS to which Queensland is a signatory, provides a framework for ecologically sustainable management of native forests for the broad range of commercial and non-commercial benefits and values that forests can provide to present and future generations. It requ ires that management planning and management of forests should maintain, to the maximum extent practicable, options for the full suite of forest values for present and future generations. Timber production is one such value providing the community with products , regional employment and economic development. Under this pol icy the production of timber and timber products is considered an appropriate and desirable forest use that can be integrated with other uses and provide benefits to the community. In providing for the harvesting of timber products, forest management should provide for nature conservation and the protection of important forest values. ESFM is given effect through a code of practice consistent with the NFPS. Code of practice for native forest timber production on the QPWS forest estate 1.2 Purpose In accord with the NFPS, and as part of any applicable forest environmental management system, the Code defines the principles , pol icies, and practices for sustainable timber production from the QPW S forest estate and seeks to ensure that: • the forest estate is assessed and protected from loss or degradation ; • harvesting is planned to ensure that social, nature conservation , forest values and environmental needs are identified and provided; • harvesting practices are safe, sustainable and protect the forest from damage and/or material or serious environmental harm. Corrective action will be taken if damage and/or material or serious environmental harm occurs ; • the forest is able to regenerate to at least mainta in its productivity and biod iversity values; and • research and development is applied to improve forest management and management practices. The Code supports broader forest management systems including forest: certification , planning , allocation, va luation and uti lisation systems. 1.3 Code application The Code applies to the harvesting of timber products (Schedule 1) from native forests on the QPWS forest estate , where operations are conducted under the Forestry Act 1959. The appl ication of the Code is based on the follow ing principles: • The Code is not a substitution or lessening of any other standard, Code or law. • The provisions of the Code are binding on all parties involved in timber production and must be incorporated into supply agreements and other contracts relating to native forest harvesting . • Where strict application of the Code will be or may be unsafe, or result in damage or environmental harm, alternative practices must be used. 2 1.4 Standards The Code defines the minimum standards to be applied to timber harvesting operations with consideration of efficiency, acceptable environmenta l impact and optimal community benefit. Code standards consider and seek to balance and be appropriate to: • the nature, scale , sensitivity and impact of use and its implications to sustainabi lity; the protection of forest, environmental and socia l values , and the natural or operational capability for restoration and recovery of disturbed areas ; • operational needs for effic ient production including: recognised industry best practice; avoidance of unnecessary penalty to good operators ; and an onus to stabil ise and rehabilitate adverse impacts caused . • environmental , resource management and conservation legislation and other obligations including the requ irements of the Forestry Act 1959, Nature Conservation Act 1992,, Environmental Protection Act 1994, Aboriginal Cultural Heritage Act 2003, Torres Strait Islander Cultural Heritage Act 2003, Queensland Heritage Act 1992, Wild Rivers Act 2005, the Environment Protection and Biodiversity Conservation Act 1999, (EPBC Act), and the Strategy for the Conservation and Management of Queensland's W etlands . • forest management pol icies such as National Strategy for Ecologically Sustainable Development 1992, Intergovernmental Agreement on the Environment 1992 and the National Forest Policy Statement 1992/1995. • forest management systems that have been developed for Austral ia (e.g. that comply with The Australian Forestry Standard). • community interest inc luding accountabi lity to the public , involvement in decision making processes, public education and the encou ragement of community ownership of environmental issues. 1.5 Code format The Code of practice is presented in two parts: Part A - Core: Incorporating pol icies and principles . Part B - Schedules : Incorporating operational prescriptions Code of practice for native forest timber production on the QPWS forest estate 1.6 Code management responsibilities 1.6.1 General Code management is based on a continuous improvement approach involving a cycle of preparation , implementation, operation, audit, review and revision. 1.6.2 Preparation QPWS is responsible for Code preparation and must liaise with: • DAFF and other government agencies to define Code standards and establish roles, responsibilities, protocols and procedures for implementation ; and • the timber industry and relevant community groups to identify issues and expectations and to establ ish procedures for add ressing conflicts or concerns. 1.6.3 Documentation QPWS is responsible for maintaining and supporting the Code and ensuring that the Code is public ly accessible. 1.6.4 Implementation The Code must be progressively and effectively implemented .

Principles of environmental care and cultural heritage protection Ensuri ng tim ber production operat ions conform to the principles of envi ronmental care and cultural heritage protection 2.1 Objective Timber production operations must be carried out in such a way that natural and cultu ral values are protected. 2.2 Principles Timber production must be planned and managed in accordance with the principles of environmental care and other legislative requirements. 2.3 Pol icy 2.3.1 Risk management A risk management approach shall be applied to all aspects of the envi ronmental management of timber production on State lands by adoption of a harvest planning framework in order to assess environmental risk and develop strategies with in the framework of the Code. 2.3.2 Protection of biodiversity 2.3.2.1 Protected Flora and Fauna -All species must be protected from any adverse effects of harvesting . The diversity of fiora and fauna, including their successional stages, in native forests must be maintained. The legislative basis for biodiversity protection in Queensland is the Nature Conservation Act 1992. Key elements of the legislation requ ire that protection measures must: • protect EVNT species; protect habitat and active breeding sites; • contribute to the conservation of indigenous species general ly; • complement the conservation goals of the regional nature reserve system; • maintain ecosystem function and essential processes; and • monitor biodiversity values and the impacts of standards. The protection measures detailed in the Species Management Profi les (SMP) are designed to meet these requirements. 2.3.2.2 Regional ecosystem management There is no legis lative requirement for protection of particular regional ecosystems on State forest, timber reserves and forest entitlement areas. 4 However the following applies: • All regional ecosystems must be managed to ensure that their ecological integrity is protected . Ecological processes, health and vitality and their abi lity to regenerate and evolve must be maintained. • The latest Regional Ecosystem numbering and status , issued by the Queensland Herbarium, Department of Science, Information Technology, Innovation and the Arts, and any subsequent revisions, as listed in the schedules of the Vegetation Management Regulation 2000 applies • Timber harvesting is not permitted in 'rainforest' reg ional ecosystems as defined by Queensland Herbarium. • The harvesting of 'rainforest' tree species is not permitted unless there are no alternatives for access or they present an unacceptable safety risk. This restriction does not apply to natural hoop pine, bunya pine and kauri pine trees occurring outside areas mapped as rainforest. • Timber harvesting is not excluded in any reg ional ecosystem on the basis of its conservation status where the Code's prescriptions or an approved alternative is applied. • Clearing associated with timber harvesting activities must be restricted in accordance with presc ribed limits (Refer Schedule 6.2). Note: Refer to Appendix 2 for definition of clearing under this Code. The protection measures detailed in Schedule 6 are designed to meet these requirements . Code of practice for native forest t imber production on the QPWS forest estate 2.3.2.3 Fire management - Wildfire control and management burning is managed under: • Part 7 of the Fire and Rescue Service Act 1990- Control and Prevention of Fires; and • Part 7 of the Forestry Act 1959 - Control and Prohibition of Fires on State Forests, Timber Reserves and Forest Entitlement Areas. The environmental impacts of fire , which includes wi ldfire and burning in conjunction with harvesting for protection and/or regeneration purposes, shall be managed in accordance with the responsibilities, procedures and standards detailed in the relevant fire management plan, policy and procedures. This includes planned burning in appropriate conditions to reduce the risk of hotter and more intense fires which can result in uncontrolled loss of carbon sequestered in biomass. 2.3.2.4 Pest and disease management Timber production activities shall be regulated to ensure all reasonable steps are taken to prevent or minimise the introduction and/or spread of pests and diseases. Management and control measures must conform to the requirements of the Nature Conservation Act 1992, the Land Protection (Pest and Stock Route Management) Act 2002, the Agricultural Chemicals Distribution Control Act 1966, and relevant pest, weed and disease strategies. 2.3.3 Protection of other elements of environmental and cultural heritage 2.3.3.1 Landscape and visitor use management Operations must conform to the requirements of the Forestry Act 1959 and the Environmental Protection Act 1994. Timber production activities shall be regulated to prevent or minimise conflicts between harvesting activities and landscape values, and recreational usage. The protection measures detailed in Schedule 7 are designed to meet these requirements. 2.3.3.2 Geomorphological features - Timber production activities shall be regulated to prevent or minimise damage to, or deterioration of, geomorphological features. 5 2.3.3.3 Soil protection - Timber production activities shall be reg ulated to prevent or minimise soil erosion, or deterioration of the soil 's physical , biological or chemical properties. Operations must conform to the requirements of the Environmental Protection Act 1994 and Wild Rivers Act 2005. The protection measures detailed in Schedules 2, 4, 5 and 18 are designed to meet these requirements. 2.3.3.4 Water and watercourse protection Timber production activities shall be regulated to prevent or minimise pollution of watercourses and systems.

Harvesting planning Effective planning provides a sound basis for ESFM and the management of environmental risk 5.1 Objective Timber harvesting must be well planned in order to protect and mainta in forest values for present and future generations . The Code establishes a framework for detailed strategic and operational leve l harvest planning that ensures timber harvesting activities are: • appropriate; • ecologically sustainable; • economically and socially responsible; and • cognisant of any relevant overarching strategic land use planning mechanism. 5.2 Principles 5.2.1 Forest planning framework Consistent w ith ESFM principles , the planning framework wi ll ensure that: • forest resources are assessed, secured and sustainably managed in balance with community, regional employment and economic development needs; • timber harvesting areas are identified taking account of community benefit , land tenure, forest capabi lity, nature conservation, other forest values, competing uses, appropriateness to site, and compatibility with existing uses and use rights ; • harvesting regimes are appropriate, ecologically sound , of acceptable impact and mainta in or improve forest productivity; • harvesting practices are appropriate for the forests long-term productivity, efficient, safe and environmentally responsible; • harvested forest is able to effectively regenerate and is protected to maintain or enhance fo rest productivity; and • planning is documented and publ icly accountable. 5.2.2 Forest protection framework 5.2.2.1 Nature conservation - Use of the forest for timber harvesting must ensure that nature conservation values are maintained. This will include the maintenance of ecological processes that sustain the forest and biological diversity while protecting rainforest, w ilderness, old growth forests and watercourse environments consistent with legislation and relevant government pol icies and agreements. 9 In a regional context the conservation framework is based on : • a nature conservation reserve system; • managing the rest of the forest area such that any special areas are protected and links are provided between protected areas; • managing timber harvesting areas in a complementary manner to ensure species and habitat protection; and • encouraging sympathetic management of adjacent other State lands or private forests . 5.2.2.2 Forest values - The management of timber harvesting must maintain the full range of forest values including biological, geological , landscape and cultural heritage over time. Significant forest values must be identified and appropriately managed. 5.2.2.3 Social amenity- The management of timber harvesting requires that socially sensitive places within or adjacent to timber production areas are to be identified and excluded from or buffered from any adve rse effects of timber harvesting. This may include exc lusion zones around significant forest use areas and the protection of existing uses and use rights . 5.2.2.4 Environmental values - Management of the forest for timber harvesting requires that soi l, water, air, noise and other environmental values be protected from loss or degradation. This may include special management areas or exclusion zones for slope, instabi lity, watercourse protection and species management, as wel l as specification of practices for avoidance , stabilisation and/or rehabi litation of disturbance. 5.3 Policy 5.3.1 This section intentionally removed from the Code Code of practice for native forest timber production on the QPWS forest estate 5.3.2 Timber harvesting areas on the QPWS forest estate Forest values and uses must take into account community benefit, overarching land use planning decisions, the purpose of the land (as per the Forestry Act 1959), forest capability, nature conservation, protection of significant forest values , competing uses, use being appropriate to the site and compatibi lity with existing uses and use rights.

Forest regeneration and growth Ensuring that the ecological integrity of the forest is protected. 8.1 Objective The objective of a harvesting reg ime is to ensure the forest can, in time, recover its pre-harvesting species composition , structure and function. This is aided by: • protecting the ecological integrity of the forest • mainta ining the potential productivity of the forest • managing disturbance 8.2 Principles 8.2.1 Management framework Timber harvesting must consider regeneration and growth by ensuring: • harvesting practice and progression facilitates regeneration; • harvested areas are regenerated naturally or artific ially; • regeneration is assessed and appropriate corrective action taken where levels are below those required to maintain site productivity; and • regeneration is protected from damage including damage from uncontrolled wi ldfire. 8.2.2 Forest productivity The area of productive forest and the level of productivity must be mainta ined and , if desirable, increased. 8.2.3 Forest regeneration and development Effective forest regeneration and development on the QPWS forest estate must be included in harvesting planning and approval. 8.2.4 Silviculture and regeneration Silvicultura l and regeneration practices must take into account: • the forest type and ecological needs for effective regeneration and optimum productivity; • the pre-existing forest condition, including the need to correct undesirable change, loss or degradation caused by past use or management; • maintenance of the genetic resources in native forests ; • the site potential and opportunities to restore or enhance forest productivity or value by appropriate silvicultural treatment; 15 • habitat tree retention guidelines and the protection and rehabilitation of nature conservation, soil and water values; and • the need for restriction of or integration with other uses of the area. 8.3 Policy 8.3.1 Maintaining the productivity of the QPWS forest estate The area and productivity of the forest estate must be maintained and where possible enhanced . The forest must be protected from damage and/or material or serious envi ronmental harm. 8.3.2 Silvicultural regimes Silvicultural regimes applied must be appropriate to the forest and retain a res idual stand consistent with the required outcomes of the Code, including: • habitat and/or recruitment habitat tree retention ; • basal area retention limits; • protection of soil , water and other forest values ; • adequate regeneration or capacity for adequate regeneration; • minimise damage to retained trees ; • long term forest productivity. 8.3.3 Adequacy of regeneration There is generally an abundance of regeneration in Queensland's native forests fol lowing harvesting . Regeneration is considered adequate when it approximates the characteristics for the pre harvest stand. Appropriate remedial action is to be taken where assessment confirms that regeneration is inadequate. 8.3.4 This section intentionally removed from the Code .

Bark may be taken from live trees in accordance with Schedu le 11. 17 Code of practice for native forest timber production on the QPWS forest estate Schedule 2: Soil assessment S2.1 Soil assessment must be used to identify soil erosion and compaction hazards, and, through re levant schedules , provide guidance for management, where high erodibility is not accepted. For further guidance , refer to the Native Forest Soi l Protection. S2.2 Sampling - The harvesting area must be sampled to provide a confident assessment of soil types. At minimum, sample upper, mid and lower slopes stratified, as necessary, by geology, topography and forest types. Sampling at representative points must be either by pit, use of freshly scraped , existing side cuts, or auger. Sample depth should be as deep as is practical and al low the subsoil to be examined. At each sample point, clear the surface litter away to expose the mineral soil surface and assess : (a) Surface condition - From a range of possible surface conditions , note if the surface condition of the mineral soil when dry is hard setting i. e. a compact, apedal surface not easily penetrated by finger. Table 2 - Soil texture characteristics Feel Coherence Gritty, not sticky Nil Grittv, sliahtlv stickv Sliaht Sponav Good Smooth Good Liqht plasticine Plastic Strong plastic ine Plastic (d) Colour - Determine the soil/horizon colour. For erodibility rating , the soil colour is based on the type horizon, which varies with the texture profile. • uniform/ gradational soil (nil/little texture change with depth) - brightest except A 1. • duplex soils (clear/abrupt texture change with depth ) - top of B horizon . Table 3 - Field soil colour descriptions Colour Mottles Description (b) Topsoil/subsoil boundary - Determine the topsoil/subsoil boundary in the soil profi le using colour, texture or other differences . This boundary may be distinct or diffuse. Once the boundary is determined sample representative examples of top and subsoil. Topsoil samples should be taken below the A 1 horizon. Sample subsoi l at 30cm if the topsoil is deep or the topsoil/subsoi l boundary is not evident. (c) Texture - Determine the texture of the top and subsoil. Take a small sample and remove stones and roots. Moisten and knead to create a bolus. Add water or soil until the bolus is of uniform consistency and just fails to stick to the fingers. Knead unti l there is no apparent change in the feel. Note the feel and coherence as it is worked. Using the thumb and forefinger, press out a ribbon and measure the length at which it fractures. Repeat. Using feel and ribbon length, determine the texture (Table 2).

Where the rating is inconsistent, further sampling must be undertaken. Dispersion - Erodibility rating generally takes into account dispersibility. If fi eld evidence (e.g. soil pipes) suggests highly dispersible subsoils , carry out a test. Place 4-5 peds or small fragments in a small volume of water and observe for 10 minutes. Note the reaction and adjust erodibi lity rating as appropriate using Table 5. 19 Low Moderate High Table 5 - Field test for soil dispersion and potential erodibility Reaction Total breaku Fragments and uite milk Obvious milkiness None/little breakup Or milkiness Moderate Moderate Slightly/non Low-Mod Code of practice for native forest timber production on the QPWS forest estate Erosion hazard - Erodibility refers to the inherent erodibility. Hazard must also consider slope, slope length , cover and erosivity. Table 6 shows erosion hazard in relation to slope. Table 6 - Erosion hazard Erodibility Rating < 10 10-<20 Low Low Moderate Moderate Moderate High Hiqh High Verv hiqh S2.4 Soil compaction Soil compaction is not generally a major problem in low intensity sing le tree selection harvesting. However, on certain soil types and under wet conditions , compaction can be a localised problem with adverse effects that may persist for 50 years or more . Compaction may be difficu lt to visually detect but rutting is a sign of serious compaction . The Code makes provision for management of compaction in various schedu les and particularly operational restrictions . In addition to the soil erodibil ity rating , the compaction rating must also be assessed and used to guide the appl ication of operational restrictions (Schedule 18). The soil compaction rating can be roughly estimated using Table 7. Table 7 - Estimating the soil compaction rating 1. Determine the base score Sand/sandy loam Loam/clay loam Lioht clav/clav 2.

S2.5 Soil moisture and drainage Soi l characteristics may provide a guide to soil moisture and drainage. Soi ls that are wet (nearing field capacity) or saturated must be operated on in accordance with Schedule 18 operational restrictions . For the purposes of operational restrictions wet soils are indicated when a bolus leaves a wet outline on the hand . A guide to soil drainage can help identify soils that may become waterlogged and subject to serious compaction (Table 8). Areas of soils likely to become waterlogged must be identified and operated on in dry weather. 20 Code of practice for native forest timber product ion on the QPW S forest estate Excessive = rapidly drains (e.g. sand dune).

The protection system provides protection to areas , subject to single tree selection harvesting, against the average annual peak stream flows. General protection principles Protection is to be provided by the establishment and management of: (i) a watercou rse protection zone around the streams , gullies and waterways that make up the watercourse network; and (ii) controls on disturbance in the harvesting area. The aim of this, and other, schedules is to minimise disturbance within the buffer and fi lter zones . This can also be thought of as acting to maintain the physical integrity and environmental values within the watercourse and buffer and fi lter zones. The watercourse protection zone 0/VPZ) is made up of a: • Buffer zone (BZ) -An area extending beyond the defining bank into the harvest area designated as a no disturbance zone. Management involves complete protection (exclusion) to maintain watercourse stability and environment. The w idth of this zone varies with watercou rse morphology. This is comprised of two components: i. Setback - The minimum exclusion distance from the defining bank that is defined by watercourse type (Table 9). ii. Slump protection - The minimum setback is extended as necessary, based on slump and other instabi lity, to protect against disturbance or other threats. • Filter zone (FZ) - An area beyond the BZ in which disturbance is conditionally permitted provided the area is maintained such as it both physically supports the BZ and protects water quality by fi ltering overland flow. The area outside the WPZ that is available for harvesting, given all other Code requirements are met, is the harvesting area (Diagram 2). 22 Availability and protection requirements When determining the availability of each particular tree or effects of a harvesting activity: • Protection requirements are determined by looking in all directions and using the prescribed protective measures applying to the visible features to provide the highest level of protection . • When determining the availabi lity of a particular tree, applying the highest level of protection and visible features principles may require a greater buffer than is warranted by the closest watercourse . • Where a higher classification watercourse meets a lower class of watercourse (transition point), the higher WPZ extends rad ial ly into the lower WPZ. • Avoid any harvesting activities that accelerate, or are likely to accelerate , erosion. W hen determining if a particu lar tree is available for harvesting, determine the protection requirement by: 1. Classify the watercourse type - At the assessment point, look both ways along the watercourse . Refer to S3.2 Watercourse classification and classify on the basis of the features providing the highest level of protection. 2. Consult the minimum protection requirements for that class of watercourse. Refer to the watercourse protection zone requirements in Table 9. 3. Consider the particular situation - Provide additional protection if warranted e.g. bank slump. Refer to the general buffer zone and fi lter zone conditions. 4. Apply the determined protection requirement. For further guidance consult: Native Forest Watercourse Protection, QPWS background information, May 2002. Code of practice for native forest timber product ion on the QPW S forest estate S3.2 Watercourse classification A watercourse can only have one classification type at any point. This class ification appl ies to both sides of the watercourse. Streams are rivers and creeks with a channel or braided channel and distinct bed and banks. Terraces and lateral flood plains may also be present. Flow may be permanent, semi-permanent, intermittent , or limited to periods after heavy rain. Streams may often exist only as waterholes or a chain of waterholes. In the absence of surface water, the bed and immediate banks will have vegetation characteri stic of frequent recharge of groundwater or be locally known water sources . Gullies are incised "U" or "V" shaped channels, conveying runoff during or immediately after periods of heavy rainfall. Bed and banks are clearly defined with at least one steep bank and has clear evidence of soil erosion/deposition . Gullies may be continuous or discontinuous and be formed as either hi llside or valley bottom gull ies . Discontinuous hi llside gul lies may have an outlet fan that may be sensitive to disturbance. Characteristic vegetation may occur on bed and immediate banks. Cross-sectional profi le is the major classification method to distinguish between U-shaped and V shaped gullies. U-shaped gul lies are typically trench-like and may be experiencing undercutting and are typically unstable . V-shaped gullies are typically more stable as the upper slopes have eroded or settled over time to attain a more stable slope. However, slumping can be present. Waterways are typically dish shaped, gently incli ned, shal low, and open depressions, which are easily discernible to the eye. They have a concave cross section and moderate approach slope. Active zones may be vegetated or sl ightly incised . These convey water after heavy rainfall but may be seasonally waterlogged with characteristic vegetation indicative of a wetter mic ro climate. 23 Diagram 1 - Watercourse types (Trench-like with unstable banks) Streams Class 1 - Active Zone >1 Orn Class 2 - Active Zone <1 Orn Once U-shaped profile has been determined, active zone width/erosion face do not alter watercourse classification. See Table 9 for protection levels. (Sloped and stable banks) V shape Gully Once V-shaped profile has been determined, active zone width/erosion face do not alter watercourse classification. See Table 9 for protection levels Waterway Shallow depression with gently inclined slopes. Active zone may be incised. Once waterway-shaped profi le has been determined and an active zone is present. See Table 9 for protection levels. Code of practice for native forest timber production on the QPW S forest estate Water features are natural or artificial waterholes , impoundments, wetlands or springs and soaks. Water features may be associated with watercourses and characterised by one or more of the following: the presence of water for more than three months in a normal wet season In the absence of surface water, characteristic vegetation indicative of frequent recharge of groundwater or locally known as associated with water featu res, may be evident Soil conditions may show evidence of prolonged water saturation • Flora and fauna debris may be present, e.g. dead water plants; mussel or crayfish shells, fi sh skeletons, etc. • Springs and soaks are areas where water flows from the surface or where the soil is damp as a result of seepage Refer to S3.3.1 (Wetland protection requirements) for detai led wetland/water feature protection requirements. Important definitions Active zone - This is a zone of active erosion or deposition characterised by either: • any erosion face greater than 10cm high; or • a scour/deposition area greater than 1 m in width. Deposited material may be loose , unconsolidated sand, gravel or water-washed stone. The zone may be obscured by litter or be associated with a significant reduction in surface cover. Width is measured across the deposited material or scour where no erosion face exists. Erosion face - An erosion face is a steep bare soil slope more or less adjacent to the zone of water flow. Height is measured vertically from the average base level of the watercourse to the top of the erosion face . Characteristic vegetation - Characteristic vegetation can occur in any watercourse type and typically indicates good subsoil moisture conditions as a result of prolonged subsoi l seepage . This vegetation is different from that found on areas adjacent to the bed and banks . For example, watercourse beds may have dead aquatic vegetation , water couch, rushes, sedges and 24 Diagram 1 Watercourse types - continued Class Ma·or Minor Water feature Active zone >1000m2 <1000m2 Saturated soil ard/0< characteristic vegetation smartweeds, whi le stream banks may have tea trees , bottlebrushes , forest red gum and river red gum.

(2) Treat paral lel , braided, or adjacent watercourses or erosion fingers separately. (3) The setback, the minimum exclusion distance from the defining bank, is determined in this table according to watercourse classification. In the followi ng Strategic Environmental Areas (SEA): The Gulf Rivers Strategic Environmental Area; The Cape York Strategic Environmental Area; Fraser Island Strategic Environmental Area; Hinchinbrook Island Strategic Environmental Area; the no-logging setback to apply is: • 50m from the defining bank of a watercourse in a Strategic Environmenta l Area , or • 100m from the defining bank of a watercourse in a designated precinct within a Strategic Environmental Area (4) The defining bank is: • the terrace or bank; or • if no bank, the point on the active flood plain that confines the average annual peak flows and is not indicated by any single major flood event (refer Diagram 2). The peak flow level may be evidenced by benches , laminations, scour or deposition or the interface between annual and perennial vegetation. (5) Slumps are a near vertical face coincident with, or separate to, the active zone which is or has been unstable . Protection requ ires an additional set back equal to 3 times the slump height. For ca lculation of slump protection , the minimum slump height to be used is one metre and then in increments of half a metre, rounding up. For banks that are in close proximity, slump protection measures shall be applied to the opposite side, where this exceeds the buffer that wou ld otherwise apply to the bank being assessed . Close proximity is three times the slump height of the opposite bank plus the setback measured horizontally from the slump face on the opposite side of the watercourse. (6) Slope limits may also exclude areas adjacent to the BZ from harvesting. 26 (7) In U-shaped gullies the slump height should include slump and erosion face height together. (8) Head scarps are the near vertical , unstable face marking the nick point in a gully or waterway. In addition to the appropriate watercourse set back, protect head scarp with an additional set back of at least Sm or three times the scarp height, whichever is greater. The appropriate watercourse filter zone is then added to make the head scarp protection zone. The head scarp protection zone extends both upstream and downstream of the nick point. Watercourse slump protection requirements are not to be added to the head scarp protection. See S3.7 for standard conditions . (9) Use U-shaped gully set back if bank is unstable. (10) Protection is primarily designed for small hillside waterways. Very large waterways, particu larly those incorporating stream-type features, must be subject to stream protection levels. A Waterway that does not have an active zone may be treated as a general harvesting area however harvesting debris and machinery disturbance should be minimised in any obvious channel. (11) The WPZ is to be measured , as a minimum, from : • the fu ll storage level of the water feature; or • the outer edge of the constructed bank/walls for artificial impoundments. Damp or saturated soil associated with the water feature is considered part of the water feature and the WPZ commences from the outside edge of the damp area. Vegetation characteristic of wet soils may be present. Additional protection requirements are detailed in Schedule 6.3.2 - Water features. S3.3.1 Wetland protection Wetlands are defined as per the Glossary. This is a general definition that includes watercourses , soaks, dams, water holes etc. Schedule 3.2 lists some more specific attributes of wetlands, also called water features in this Code. Protection types Wetlands, or water features , have two aspects of protection that must be applied: • Physica l protection (buffer and filter zones as prescribed in Schedule 3); and • Habitat protection (as prescribed in Schedule 6.3.2). Both of these protection requirements are applied simultaneously and are measured from the top of the defining bank (S3) or the outer edge of saturated soi l/characteristic vegetation (S6.3.2). Wetland protection requirements Code of practice for native forest timber product ion on the QPW S forest estate 1. Classify the watercourse and any wetland/water feature a. Using Diagram 1 in S3.2, class ify the watercourse at the assessment point by looking upstream and downstream along both sides of the watercourse. Classify on the basis of the features providing the highest level of protection . A watercourse can only have one classification type at any point and this appl ies to both sides . b. Using Diagram 1 in S3.2 , identify any water feature components; the ful l storage level (if any), the defining bank (if any), the extent of any saturated soil and the extent of characteristic vegetation . Use Diagram 1, S3.2, to classify the wetland/water feature as either a major or minor wetland based on the area of the full storage level, if present, or the area of satu rated soil/characteristic vegetation. 2. Consult the minimum protection requirements for the class of watercourse and any wetland/water feature . Refer to the watercourse protection zone requirements listed in Table 9 in S3.3. Also apply the wetland habitat protection requ irements from S6.3.2, if required. 3. Apply additional wetland protection in the following situations: a. Where the wetland/water feature is located within the defining banks, but is not in the main channel, the S3 and S6.3.2 buffers stil l need to be applied 1. b. A high impact earthworks2 buffer of 200m must be applied to the wetland/water feature and/or watercourse 3 where these are located in a: i. Great Barrier Reef catchment; ii. Wetland located on a Map of Referrable Wetlands ; iii. Wetland Protection Area; If no high impact earthworks are required, only the required S3 watercourse and S6.3.2 wetland habitat buffers are to apply to other harvesting operations. 4. Consider the particular situation - Provide additional protection when assessing trees for removal if warranted , e.g. bank slump, tree cannot be felled away from the buffer, when 1 These types of wetlands/water features have very high conservation values due to their ability to function as refugia between inundation periods 2 Refer to definition of high impact earthworks in S26 of the Sustainable Planning Regulation 2009, page 187. 3 Refer to SPP 4111 , requirements for a HES wetland , T able2, page 9. Also conforms to requirements in Regional Vegetation Management Code for Southeast Queensland Bioregion - version 2, AS T.3. 27 marking trees for removal. Refer to the general buffer zone and fi lter zone conditions . 5. Apply the determined protection requirements. Overlap any wetland/water feature protection over the watercourse protection zone. S3.4 General conditions Protection must be increased, as necessary, to take account of the particu lar situation . S3.5 Buffer zone standard conditions BZ standard conditions are: • No tree is to be felled if any part of the tree above ground (bole or buttress) is within or touches the BZ. • Machines are not permitted in the zone unless at a crossing. • Roading or snigging is prohibited along the bed of any watercourse. • New road crossings (ac ross streams or class 1 gully), major snig track crossings and minor snig track crossings on U-shaped gullies must be marked in the fie ld. Crossings must: be located in straight, stable sections with low banks; be aligned at right angles to water fl ow; be more than 200m from another crossing where terrain permits (and in accordance with the Operating Guidelines); not involve pushing of soil or debris into watercourses or bank disturbance beyond the alignment; be constructed using gravel or corduroy with minimal earth fil l. Use a cu lvert, temporary as necessary, if water is flowing or will flow during use; and have diversion drains on approaches and immediately stabilise and rehabilitate the crossing at completion of use. • Minor snig tracks by rubber-tyred machines may only cross V-shaped gullies and waterways where the tota l height of any erosion face associated with the active zone is less than 30cm, and when: Slump is not present outside the active zone , i.e. on the bank; operationally essential ; the bed is dry; earthworks are not required ; use does not create an erosion channel; the crossing must be moved to another site as soon as a wear track becomes evident. • Trees are not to be fe lled into the BZ unless they are done so in accordance with S3.7 . • Trees accidentally felled into the zone must be removed with minimal disturbance to soil or vegetation. • The burn ing of accumulations of fuel in the BZ must be avoided. Code of practice for native forest timber product ion on the QPWS forest estate S3.6 Filter zone standard conditions FZ standard conditions are: Harvesting is conditional to compl iance with filter zone conditions . • Operations are prohibited when soi ls are wet (nearing field capacity) or saturated. • Fell trees away from the BZ to minimise soil or understorey disturbance. • Trees are not to be fel led into the FZ unless these can be felled with minimal disturbance to soil surface cover or understorey. Disturbed areas are to be stabilised as necessary. • Tracked snigging machines (e.g . dozer) are not to operate within the FZ except fo r the construction of, and/or snigging across, designated crossings. • Major snig tracks must not enter the fi lter zone unless at a crossing. • Rubber-tyred snigging, forwarding and all fel ling machines must minimise disturbance and use walk-over techniques where possible . • Harvesting debris which represents a fire hazard to reta ined trees greater than 10cm dbhob is to be removed and placed at least 2m from the tree. • Extraction must avoid creation of an erosion channel. This may be assisted by using mechanical harvesting equipment, log-end lifting , minimising log turning and , as appropriate, external winching. • Actual or potentia l erosion channels created by extraction are to be stabilised by placement of litter and careful drainage . 3.7 Head scarp protection zone standard conditions Head scarp protection zone standard conditions are: • Head scarp protection zones are to be added to the appropriate watercourse setback (i. e. buffer). • Crossings for new roads and snig tracks (minor and major) must not be located within 10m (up and downstream) of a head scarp protection zone. • Crossings for existing roads and snig tracks (minor and major) that are located within 10m (up and downstream) of a head scarp protection zone, may be used where continued use wi ll not accelerate erosion. • No machinery (felling or snigging) is permitted within the head scarp protection zone . • Trees fel led from withi n the fi lter zone must be felled to the outside of the head scarp fi lter zone . S3.8 Additional tree-felling rules for felling across V-shaped gullies and waterways. The fol lowing prescriptions are additional to those in S3.5 and S3.6, and allow for the legitimate 28 harvesting of timber and timber products in the vicinity of stable watercourses where all other Code requirements can be met. The intention is always to fully protect the BZ vegetation and the integrity of the bed and banks of the watercourse. BZ The following conditions for protection of the BZ may apply: • Trees are not to be felled across the gully or waterway when the soi l is wet (nearing field capacity) or saturated . • Felling ac ross the gul ly or waterway is not to occur if a flood or storm is imminent, e.g. if the weather forecast is for storms or heavy ra ins that is likely to result in seasonal flow. • Felling is not to occur if such action is likely to trigger accelerated erosion or instabi lity of the bed or banks . • The felled trees must bridge the active zone. • The trees must be promptly removed , e.g. with in two days. • Harvesting debris must be removed from the BZ without the need for the machine to enter the zone and the zone is not damaged or an erosion channel created . FZ The intention is to ensure that the FZ is left in a condition to fu lfi ll its filter function. This means minimal soil and understorey disturbance and avoidance of compaction or creation of erosion channels in the zone. Felling into the FZ may occur where the conditions for protecting the BZ are met and: • Any erosion channels are repaired and stabilised • Trees can only be felled with in a FZ if minimal disturbance to the understorey can be achieved • Harvesting debris which represents a fire hazard to reta ined trees greater than 10cm dbhob is to be removed and placed at least 2m from the tree. Code of practice for native forest timber production on the QPW S forest estate S3.9 Impacts on the Filter zone from the harvesting area The intention is to ensure that trees fel led from w ith in the harvesting area are harvested and removed in such a way that the FZ is left in a condition that will allow it to fulfil! its filter function . This means minimal soil and understorey disturbance and avoidance of compaction or creation of erosion channels in this zone. Trees growi ng in the harvesting area that are not available for harvesting because their lean dictates that they cannot be fe lled away from the FZ, may be felled into the FZ subject to the following conditions: • There is a natural gap in the FZ vegetation large enough to accommodate the felled tree . • The tree head does not fal l into the BZ. • Harvesting debris which represents a fi re hazard to retained trees greater than 10cm dbhob is to be removed and placed at least 2m from the tree. • Harvesting debris is removed from the FZ without the need for the machine to enter the BZ and the FZ vegetation is not damaged or an erosion channel created. • Any erosion channels created in the FZ are repaired and stabi lised. 3.10 Harvesting area general conditions The general harvesting area is to be operated to avoid excessive soi l disturbance and artificially concentrating or directing overland flow into the watercourse protection zone (VVPZ). Minimum distances from the W PZ for drainage discharge are: • landing and snig track drainage 1 Orn • road drainage 20m • fuel ing, fue l storage/waste disposal 40m Refer also to S9.2 for critical locations. 29 Cattle tracks and disused roads - Watercourse protection measures do not apply to cattle tracks and disused roads unless they become an active watercourse. Avoid disturbance, cross at right angles and do not snig along cattle tracks and disused roads where possible. Alluvial fans -Alluvial fans may be sensitive to disturbance. Fans below hi llside gullies should be operated cautiously under dry conditions using fil te r zones or more stringent conditions over the full area. Flood plains - Flood plains are generally subject to watercourse protection requirements. The configuration of these features can be highly variable and harvesting must be careful ly planned and considered . Harvesting is not allowed on narrow lateral flood pla ins , including when they are enclosed by terrace banks (Diagram 3). Major flood pla ins or broad lateral flood plains may be complex channelised systems. Watercourse protection requirements must be applied to each of the flood plain features and the remaining area may then be planned for harvesting. W here harvesting is deemed acceptable: • plan operations to avoid wet or flood prone periods; • cease operations before soils become wet or saturated; • take particular care with cross ings to avoid flood scour; • use walk-over practices and minimise and stabil ise any ground disturbance; • manage debris to avoid turbulence, secondary damage or a fi re hazard; and • avoid activities or outcomes that may accelerate development of declared animal and plant populations .

Table 10 - Majority slope limits (degrees) S4.2 Procedure The procedure for slope protection is : • determine the soi l erodibil ity rating as prescribed in Schedule 2; Low 30 • determine the slope classes using a cl inometer to measure average slope over representative distances of 20m; and • apply the majority slope limit to each soil erodibility rating area . Areas are deemed operational if less than 10 percent of the area is outside the slope limit (Diagram 4). Diagram 4 - Majority slope limits Majority slope limits Moderate 25 31 Hi h 20 Code of practice for native forest timber production on the QPWS forest estate Schedule 5: Instability exclusion zones SS.1 General Harvesting and associated activities must be excluded from areas of obvious past, present or potential instability. Evidence of instability may be present in the form of exposed sl ip/sl ump faces, or suggested by ground cracks, geology or hummocky topography. It is important that these areas are not destabilised physically by removing trees particularly the larger trees above the unstabie area, or by the redirection of road and track drainage into the unstable area. Diagram 5 - Instability exclusion zone SS.2 Restrictions Road construction must avoid areas of instability and ensure that drainage is not directed into unstable areas. Harvesting must be restricted in and around areas of instability. Large areas of instability must be excluded from the harvesting area . Small areas may be included but subject to restriction. Areas of instability should be judged on the particular circumstances and likely level of interference . A minimum exclusion zone must provide: • a distance above the slip face equal to three times the height of the face or 1 Orn, whichever is greater; • a distance of 1 Orn below the toe of the slip or unstable area (Diagram 5); and • a minimum distance of 1 Orn either side of the unstable area . Instability exclusion zone Retain trees above area and ensure road or track drainage is not directed into the unstable area 32 Minimum of or • 3 times scarp height Whichever is greater / 1 Ometres below toe or ground fracture Minimum of 10m either side of the unstable area Code of practice for native forest timber production on the QPW S forest estate Schedule 6: Nature conservation S6.1 Species protection S6.1.1 In add ition to section 2.3.2.1, where threatened species (refer Glossary for definitions) are known or are likely to occur and are likely to be impacted on in the course of harvesting operations , protective measures consistent with systems and prescriptions provided by relevant government agencies are to be applied. S6.2 Regional Ecosystem (RE) protection S.6.2.1 Harvesti ng is not permitted in 'rainforest' regional ecosystems defined by the Queensland Herbarium. Once regional ecosystem boundaries are establ ished, trees must not be felled into rainforest regional ecosystems. Distinct regional ecosystems are recognised down to one hectare in area. S6.2.2 Individual rainforest tree species >25cm dbhob in non-rainforest reg ional ecosystems must be protected from harvesting damage unless there are no alternatives for access, or they present an unacceptable safety ri sk. This restriction does not apply to natural hoop pine, bunya pine or kauri pine trees or other rainforest species commonly found in the lower stratum of non-rainforest ecosystems. Standing dead rainforest tree species that are not required fo r habitat may be salvaged (harvested). S6.2.3 In the context of the Code, the construction or re-opening of access tracks and/or snig tracks through rainforest reg ional ecosystems is not permitted unless this is in accordance with Core section 1.3. S6.2.4 RE Planning Clearing In the context of timber harvesting, clearing will be minimised in all REs. Where it is demonstrated that there are no practical alternatives, limited clearing is permitted for new roads, landings , major snig tracks and camping and processing sites . (See Appendix 2 for a definition of clearing that applies under this Code). 33 Where there are no economic or practical alternatives , the following clearing limits will apply: • endangered REs - no clearing as defined in Appendix 2 of the Code; • of concern REs - clearing to be minimised and in all cases the total area of clearing will be restricted for individual patches or REs in accordance with Table 11 below; and • not of concern REs - clearing to be minimised . Where prescribed clearing limits listed in Table 11 for "of concern" REs are likely to be exceeded, or if an endangered RE boundary or type is in dispute, Forest Products wil l develop an accurate RE map of the area in question at an operational scale as part of the OHP process . This map can be used for seeking OHP approval when required. This action may be undertaken initial OHP preparation or at any time Forest Products becomes aware of an issue during the course of harvesting . Mapping The avai lable RE mapping (generally at 1: 100,000 scale) w ill be incorporated into the OHP documentation. Forest Products will obtain the RE mapping from the relevant agency or Queensland Herbarium. QPWS may request maps from Forest Products on a case-by-case basis for endangered REs where the boundary is changed. Contiguous areas When calculating a 'contiguous area', the patch of an individual RE type within the OHP boundary and an adjoining RE of the same type outside the harvesting area but within the adjoining State forest estate wi ll be considered as a whole. Rainforest REs Construction or re-opening of roads and snig tracks through rainforest REs is not general ly permitted. However QPWS may approve, on a case-by-case basis, the construction or re opening of roads and snig tracks through rainforest REs where there is no alternative access . QPWS will consider the alternative access options, taking into account net environmental impacts, cost, safety, and practica lity.

S6.2.5 Definition of clearing For a definition on clearing, refer to Append ix 2. S6.3 Habitat trees S6.3.1 General Habitat trees and recruitment habitat trees are those that are required to be retained for wildl ife conservation purposes. The following standard requirements for the retention of habitat and recruitment habitat trees must be applied to all harvesting operations. Alternative approaches may be permitted where the proposal conforms to the recommendations of the report by the Habitat Tree Technical Advisory Group entitled "Managing Habitat Trees in Queensland Forests", (Apri l 1998), or provides equal or better environmental outcomes. This includes applying the "Landscape Approach to Habitat Tree Protection and Management" detai led under section Q4b of the report. S6.3.2 Habitat tree and recruitment habitat tree requirements by forest types Note: Where referred to in this schedule, "per hectare" habitat tree and recruitment habitat tree requirements apply to each hectare of the harvesting area. This is consistent with retaining the desired spacing of habitat and recruitment habitat trees at a landscape level. A habitat or recruitment habitat tree may be either merchantable or non-merchantable. 34 Hardwood forests within the greater glider range A minimum of six live habitat trees and two recruitment habitat trees per hectare will be designated and retained throughout the harvesting area. Hardwood forests outside the greater glider range A minimum of four live habitat trees and one recruitment habitat tree per hectare wi ll be designated and retained throughout the harvesting area. Cypress forests Where available, a minimum of two live habitat trees and one recru itment tree per hectare wi ll be designated and retained throughout the harvesting area . Where the number of habitat trees avai lable does not meet the required standards, additional recruitment habitat trees must be selected according to Table 12. Code of practice for native forest timber production on the QPW S forest estate Table 12 - Selection of Habitat and Recruitment Trees Hardwood forests within the Hardwood forests outside the Cypress forests greater glider range greater glider range Number of Number of Number of habitat trees recruitment habitat trees available/ha habitat available/ha trees/ha 6 2 4 5 4 3 4 5 2 3 7 1 2 8 0 1 10 0 11 Where habitat trees occur uniformly on the harvesting area, additional recruitment habitat trees must be retained according to Table 13 where >50 percent of the basal area of the stand (on a per hectare basis) is to be removed. The most appropriate recruitment habitat tree is to be selected using S6.3.4. W here the required numbers of these additional trees are not available in a particular size class, trees must be retained in the size class below at a rate of 1.5 trees for every tree below the required number (or round up if the number is a fraction). Table 13 - Additional recruitment habitat trees where >50 percent of basa l area is removed Number of additional Size class (dbh in cm) recruitment habitat trees to be retained per hectare 60 - 70 2 50 - 60 3 40 - 50 4 30 -40 5 20 - 30 6 10 -20 9 Water features/Wetlands All trees greater than 60cm dbh must be retained as habitat trees or recruitment habitat trees in areas designated as water features/wetlands and within a 30m zone around water features (water features are defined in Schedule 3 Watercourse protection, see also definition of Wetland). S6.3.3 Habitat tree selection criteria The aim of habitat tree selection is to retain the larger living trees that contain the most hollows Diagram 6 - Habitat tree 35 Number of Number of Number of recruitment habitat trees recruitment habitat available/ha habitat trees/ha trees/ha 1 3 4 6 7 2 1 1 3 0 4 and are likely to persist over several harvest rotations. Selected habitat trees must be dominant or co-dominant trees , w ith at least one 'hollow' 10cm or greater in diameter. The 'hollow' must be visible and greater than 2m above the ground (Diagram 6). Habitat trees, should be evenly spaced wherever possible on each hectare. Where there are more than the required number of habitat trees, the following hierarchy w ill be used to select habitat trees: 1. Size - Habitat trees greater than 80cm dbhob must be selected wherever available, as they have the highest chance of containing large or mu ltiple hollows. Further selection must be made in the 50 80cm dbhob range. Smaller hollow-bearing trees , less than 50cm dbhob, are selected only when sufficient larger trees are not available. 2. Habitat characteristics - In addition to having a hollow, the presence of mistletoe, epiphytes , fungal bodies, termite nests and 'deformities' that provide habitat. 3. Species - Habitat trees must be chosen in proportions which reflect the overall species mix present on the site, unless there are documented special reasons to favour species that are particularly valued by wi ldlife. Code of practice for native forest timber production on the QPWS forest estate Habitat tree S6.3.4 Recruitment habitat tree selection criteria The aim of recruitment habitat tree selection is to retain the trees with the greatest potential to become habitat trees in the shortest time. These recruitment habitat trees shall be from a species known to develop hollows earlier, that live a relatively long time (this may include, but is not exclusive to, Eucalyptus, Corymbia and Angophora species) and be as evenly spaced as possible . Consistent w ith the above requirements, the following hierarchy of criteria must be used in the selection of recru itment habitat trees: • Trees which are at least co-dominant from within a range of size classes representative of the stand and with habitat forming characteristics, including damaged or senescing crowns, visible termite nests or other deformities , or, if these are not available; • Other trees with habitat forming characteristics, including damaged or senescing crowns, visible termite nests or other deformities, or, if these are not available; • Trees which are at least co-dominant that don't as yet exhibit habitat forming characteristics. 36 S6.3.5 Inclusion of trees from exclusion zones, other retained trees and standing dead trees No more than 50 percent of the habitat trees and recruitment habitat trees in any one hectare can be counted from exclusion zones. Trees retained because they contain active bird nests, other native fauna or termite nests with hollows, and trees retained under SMPs (e.g. yellow bellied glider feed trees), may be counted as habitat or recruitment habitat trees provided they meet the selection criteria. Standing dead trees and stags with hollows, or deeply fissured or cracked bark , must be retained unless they are a safety or fire hazard. Standing dead trees and stags that contain an active nest or any raptor nest must be reta ined (see also S11.2).

To minimise fire damage, felling must not accumulate harvesting debris within 2m of habitat trees and recruitment habitat trees , and fe ll ing or snigging must not physically damage the bole of the tree. Habitat trees and recruitment habitat trees are to be retained in subsequent harvesting operations including sales of fi rewood, fence posts , landscape materials, poles and silvicultural thinning (for retained tree damage or regeneration issues refer also to S10.3). S6.4 Feed, shelter and nest trees S6.4.1 Trees sheltering animals - Trees in which any native fauna species is visible must be protected from harvesting or harvesting damage until the animal moves out of danger of its own accord . Cutters shall inspect trees for the presence of native fauna species. S6.4.2 Feed trees - Feed trees will be protected in accordance with the relevant SMP. S6.4.3 Trees with active nests - Trees and shrubs containing active bi rd nests must not be harvested, damaged or otherwise interfered with during harvesting. Active bird nests are those of native species that contain eggs , sitting birds, nestlings or are in the process of being constructed. Where there is a possibility that a nest is active, a precautionary approach must be used and the nest must be protected . Trees with nests of birds of prey (raptors), which are re-used year after year, must be protected whether active or not. Tree markers and/or cutters shal l visually inspect trees for active bi rd nests and identify those trees requiring protection. Where the species cannot be identified or is not a species for which an SMP has been prepared , the fol lowing harvest exclusion zone will be establ ished around the nest or nest tree: • For nests greater than 50cm in diameter - a radius of 50m around the nest tree. • For nests 50cm or less in diameter - equal to the height of the tallest tree in proximity to the nest; and 38 • For understorey and ground-nesting species equal to the height of the tallest tree in proximity to the nest.

All proposed harvesting areas must be assessed for cultural heritage values and relevant values protected before operations can begin . Relevant sources of information for protective measures are: • QPWS Cultura l Heritage Management Manual , and • Aboriginal and Torres Strait Islander Cultural Heritage Database and Aboriginal and Torres Strait Islander Cultural Heritage Register administered by DATSIMA S7.3 Landscape and visual protection S7 .3.1 General The objective of th is Schedule is to minimise loss or degradation of visual resources , recreation settings and visitor opportunities resulting from timber harvesting operations. In particular, th is schedule establishes standards for protecting areas that are identified for landscape protection and/or visitor use. Where areas are zoned for landscape protection and visitor use, both sets of protection measures must be applied . S7.3.2 Landscape protection Feature protection area (FPA) protection measures inc lude: • Where forest management plans or FPA management plans exist, the management and protection of FPAs must be in accordance with these. • Where forest management plans or FPA management plans do not exist, timber harvesting must be excluded from gazetted or proposed FPAs; and • A 20m harvesting exclusion zone must be appl ied to all gazetted or proposed FPAs. 39 Visual resource protection area (VRPA) protection measures include: Where forest management plans exist, the management and protection of VRPAs must be in accordance with these; Where forest management plans do not exist, harvesting operations should range from being temporari ly apparent (i. e. apparent for less than 12 months) to not evident. When apparent, the period of impact should not exceed one year from the date of commencement of harvesting of the VRPA. Alterations to the landscape must be minimised and not significantly alter the form, line , colour or texture of the natural landscape. VRPAs seen primarily in the foreground, (vegetation density: open - 500m, sparse 100m, dense - 20m) shall be protected by: • enforcing a 10m non-clearing zone around viewi ng points , roads and walking tracks; • limiting canopy reduction to a maximum of 50 percent in any 0.2ha; • breaking down all harvested tree heads within safety constraints to a height of less than 1 m with in 30m of formal viewing points , roads and walking tracks; • applying a machinery exclusion zone of 20m around viewing points, roads and walking tracks; • promoting the retention and development of large trees with in the foreground of viewing points, roads and walking tracks by removing upper diameter cutting limits and reta ining the largest diameter live tree , regard less of age or crown score within each hectare of the foreground ; • reducing the visual impact of roads and snig tracks by limiting the length of track visible within safety constraints. This can be achieved by changing direction on a regu lar (short section or curves) or irregular (in line with the form of the landscape) basis, or by reta ining vegetation around those sections of the harvesting area ; and • not positioning landings within the foreground of viewing points, roads and walking tracks. VRPAs seen primarily in the middle ground (0.5km - 6km), or background (6km to 16km) shall be protected by: • ensuring harvesting operations are spatially and temporally planned for to reduce the amount of disturbance in the forest area at any time; Code of practice for native forest timber production on the QPWS forest estate • ensure that harvesting area edges and boundaries conform to the natural landform; • positioning harvesting areas to protect visible skylines; and • limiting canopy reduction to a maximum of 50 percent on any one hectare site . S7 .4 Protection of visitor areas Formal visitor node protection measures include: • Apply a 1 00m harvest exclusion zone where harvesting adjoins a formal visitor node and around the perimeter of the formal structures (e.g. car parks, shelter sheds , picnic tables etc .). • Restrict log haulage past formal visitor nodes to outside peak visitor use times; and • Plan harvesting operations outside the exclus ion zones to be visually and audibly inconspicuous at peak use times. Informal visitor node and formal visitor road and track (including forest drives) protection measures inc lude: • As for VRPAs seen primarily in the foreground. • Restrict log haulage along formal visitor roads to outside peak visitor use times . • Plan harvesting operations to be audibly inevident from visited areas during peak use times. No specific protection measures are requ ired for informal tracks or trai ls. 40 Code of practice for native forest timber production on the QPWS forest estate Schedule 8: Forest road and track management SS.1 General This schedule sets out the management standards to be applied to the planning, construction and maintenance of forest roads and tracks. SS.2 Planning Roads and tracks must be planned to ensure efficient and economic harvesting and haulage practices and with the least overall adverse environmenta l impact. Planning must provide a road network of a standard (Table 14) and density that is the minimum necessary to achieve operational efficiency. This must include: • consultation with interested groups including re levant authorities where access is proposed to join a gazetted road ; • a survey of the proposed road alignment at an intensity appropriate to the road standard to prove the alignment, check watercourse cross ing points and identify construction or environmental issues. Soil erodibil ity (Schedule 2) should be assessed during the survey. Alternatively, where a survey is not conducted , soil erod ibility must be accepted as being high ; and • advice and endorsement from an expert where primary or secondary access roads or where structures, instability, drainage design or safety issues are involved. SS.3 Location Roads must be located to best optimise: • protection of forest values and exclusion zones; • catchment and watercourse protection minimise : interference with natural drainage systems; where possible, the catchment area above the road; and the number of watercourse crossings. • road alignment - by minimising the tota l necessary road length, tortuosity and grade; • forest management - maintain or enhance forest management; • landscape values - fitting roads into the landscape and minimise the alteration of natural features to avoid or minimise adverse visual impact; • minimise earthworks where possible and facilitate drainage by: 41 locating the road on naturally drained or easily drainable features such as ridge tops , benches and gentle slopes; avoid ing areas prone to instabi lity or flooding; avoiding the use of box cuts, which are difficult to drain , unless overall impact is less than alternative locations ; limiting side cutting and avoiding potential instabi lity by restricting construction to side slopes less than 30 degrees; and balancing cuts and fills to minimise transport or wastage of fill material. Code of practice for native forest timber production on the QPWS forest estate S8.4 Basic design guidelines Design standards must be the minimum to achieve the required road function and be capable of carrying the anticipated frequency, type and speed of traffic safely while protecting environmental va lues. Design standards must be appropriate to site conditions to ensure stability, maintain integri ty of fi ll and cut banks, and provide adequate drainage and sediment control measures. Access class , standards and suggested densities are indicated in Table 14.

In general , harvesting road access will entai l construction of temporary tracks that may serve larger areas, as shown in Table 14. (2) Formation types and design features are illustrated in Diagram 7. (3) Haul tracks generally use a flat-bladed formation. These must be located and al igned to involve the absolute minimum in clearing and earthworks to provide for practical use and safety. Avoid box cuts unless absolutely necessary. Formation should avoid creation of an edge berm. Location must use natural features to facilitate natural drainage. Wet spots in the track surface must not be bypassed but be either drained, raised or corded. Surface drainage must maximise the use of natural drainage and: 7 degrees 9 degrees 8 degrees 42 • ensure any edge berm is breached at water bar spacings to permit drainage; • consider the use of inverts or roll-over water bars for cross drainage during use or where the track has to remain trafficable; and • use water bars only where the track is no longer required . (4) Pavement width and surface must be matched to road use. Gravel is necessary to ensure traction , avoid rutt ing and to mainta in effective drainage. Code of practice for native forest timber production on the QPWS forest estate (5) Clearing width may be extended to avoid a safety risk. Extend by the minimum necessary to correct the risk or cons ider alternatives such as restricting traffic to "one way". (6) Grades - Steeper grades may be permitted where construction results in less disturbance and can be safely used. Gravel may be needed to access steeper slopes. (7) Drainage must be in accord w ith Schedule 9. S8.5 Design of watercourse crossings Existing crossings must be used provided they are capable of accommodating the traffic and are stable, safe and pose no envi ronmental threat. Proposed or upgraded crossings on haul roads must be capable of accommodating the traffic and watercourse flows, and be safe, stable, and not pose an environmental threat. Crossing sites must be identified and located before construction commences. Crossings must be sited in straight sections of the watercourse where practicable with low and stable bank formations where approaches will cause minimal disturbance (Diagram 8). A lign crossings, as close as practica l, at right angles to the water flow. Avoid deeply box cut approach slopes and design drainage to divert road water to stable vegetated areas so it can be fi ltered prior to entry to the watercourse (See Schedule 3). Design and location must be consistent with watercourse protection (Schedule 3) and the fol low ing : Bridges and culverts are the preferred method of cross ing permanent or intermittent watercourses . These must be designed and engineered to have structural integrity and must: • be sized to cause minimal impedance to flow and, at minimum, conta in a 1 in 5 peak flow event and withstand a 1 in 10 peak flow w ith minimal structural damage including provision for overflow to carry flood flows; • provide for protection and stabil ity of abutments, bed and adjacent banks; • prevent any soil or gravel fill on the deck from falling into the watercourse; • prevent water from ponding on the upstream side of the crossing during normal low-flow events; • prevent any water from ponding on the bridge ; and • provide for any necessary passage of fish or other aquatic life . 43 Causeways and fords are suitable for crossings that are used infrequently, where usage occurs during periods of low flow or where regular flooding prevents economic or effective bridge construction. Sites must be natural ly stable or engineered to provide function and environmental protection. The cross ing must be installed at the existing bed level height so as not to impede water flow and movement of aquatic species and at the same upstream-down-stream gradient as the watercourse. 6 Approaches must be gravel led or otherwise stabil ised to minimise turbidity in wet crossings. Temporary crossings must be minimised. Crossings must not involve earth fi ll but may be gravel led or corduroyed to bed level height. Use a temporary culvert if the cross ing will be used when water is flowing , and use would otherwise create a threat to water quality. A temporary culvert is a drainage structure that allows water to be channelled under or across the road and is temporary in natu re and is removed and stabilised. 6 These requirements conform to the requirements of the Code for self-assessable development: temporary waterway barri er works ('NWBW02) Code of practice for native forest timber production on the QPWS forest estate Diagram 7 - Road formation types and design features Road formation types and design features Type Side Shoulder A B C D drainage (7) Pavement Crowned formation Cross fall 1-3 degrees .

Bench cut batter or use a catch drain above the cut if batter is >3 metres in height Code of practice for native forest timber production on the QPWS forest estate Diagram 8 - Watercourse crossing S8.6 Construction Construction methods and standards shall reflect best practice. They must include the following: • Al l persons involved in road construction and maintenance must be properly trained in the techniques and precautions required to prevent soil erosion and water pol lution. • Equipment must be selected on the basis of efficiency and the abil ity to minimise soil disturbance. Excavators are preferred for major earthworks and watercourse crossing construction. Waste and hazardous substance management must conform to Schedule 17; Pests, weeds and disease management must conform to Schedule 15; Construction of primary and secondary access roads must be scheduled for the drier periods of the year to: avoid accelerated soil loss or degradation of water quality; allow for consolidation; and take advantage of adequate soi l moisture for soi l working and compaction. Construction of primary and secondary roads must be undertaken in planned stages to ensure that the area of disturbance is minimised at any one time and then progressively stabilised. Clearing , where permitted, must be undertaken in stages to minimise the tota l area of exposed soil at any one time. Debris should be retained for temporary stabil isation. Width must be the minimum to permit efficient construction, allow the road surface to dry, and to provide an appropriate line of sight. The maximum clearing width may be extended to el iminate any safety hazards. 45 Areas cleared beyond the earthworks must retain the maximum possible amount of topsoil/ground cover to maintain stability. Trees or other products should be salvaged from the al ignment wherever possible. Clearing waste (organic, soil or rock) should be used, where possible, to stabi lise earth banks. It should not be included in the road fil l, pushed into exclusion zones or placed where it w ill damage the forest. Topsoi l that is stripped must be stockpi led for use in stabilisation and rehabi litation ; Earthworks must be kept to a minimum in line with the long-term road stability and efficient future maintenance. Where practical, cuts and fills should be balanced along the road to minimise costs and to use the earth within the road alignment. Batters fo r earthworks must be designed to be no steeper than the in-situ soil stabi lity allows and take into account the dip angle of the rock. Where this is not possible, cut batters must be benched to reduce the exposed vertica l face. Batters must be graded to control erosion, aid establishment of vegetation and to minimise visual impact. Batters must be stabilised during and following construction, and before the removal of machinery, by: constructing catch drains above the cut batter; sloping or stepping of batters; providing flumes or other protection on drain outlets on fill banks; and using surface covers or revegetation . Code of practice for native forest timber production on the QPWS forest estate Quarries and borrow pits should where possible be sited to avoid adverse visual impact and be: minimum in number and size ; constructed with stable batters and drained and maintained during use; and stabil ised and rehabil itated after use. For primary and secondary roads, compaction by other than gravel or timber trucks must be used to provide adequate strength to load bearing sections and prevent rutting and subsequent damage during use. Surface gravel must be smoothed and compacted to create a water shedding and lasting pavement. Roads and tracks are to be provided with adequate drainage in conformity with Schedule 9, to protect the road , avoid soi l erosion and minimise watercourse sedimentation. Wherever practical , drainage should be instal led in advance of other construction to keep the works as dry as possible. During construction all disturbed areas must be adequately drained or stabilised when there is a reasonable expectation of an extended period of heavy rainfall , storm, cyclone or other event. Drainage and stabilisation measures may include: stockpiling loose materials where they can be protected from erosion; draining the surface using cross fa ll and controlling surface run off by using natural drainage patterns , table and side drains, cu lverts, inverts or water bars; and discharging waters on stable areas , undisturbed vegetation or a hardened site/structure and not directly into watercourses or on exposed soil or fi ll slopes . • Watercourse crossing construction must be managed to minimise impacts to water quality and disturbance of watercourse bed and banks. Approaches to crossings must provide for drainage diversion on to vegetation and sediment traps so that unfiltered run off cannot fl ow directly into watercourses . Construction must ensure that: clearing, where required and approved, is confined to the alignment, and trees are fe lled away from the watercourse ; disturbance to bed and banks is minimised; spoil is not pushed into the watercourse ; machinery is not used in the watercourse unless essential, and then confined within the al ignment. Excavators are preferred ; 46 debris and temporary structures are removed unless removal poses a greater risk, and ; bed and banks are stabi lised after construction . • Pavement materials and surfacing must provide a stable, load bearing and smooth surface that will provide for overland flow and shed water. Suitable, on-s ite or imported, materials consisting of a mixture of graded stone and clay binder must be placed and compacted. Thickness depends on material quality, load bearing requ irements and the size of the largest particle. As a guide, depth should be approximately 1.5 to 2 times the size of the largest partic le to provide a smooth running surface. Patch gravelling should be done as necessary to maintain function and/or avoid road surface damage. • Signs should be erected as necessary. Signs, where used, should conform to the QPWS Sign Manual and , as appropriate, comply with either the Manual of Uniform Traffic Control Devices (MUTCD) and the Traffic and Road Use Manual (TRUM) and/or TC Signs 7. S8.7 Reopening of access Re-opening of access must restore the road, drainage systems and watercourse crossings to Code standards, including stabil isation requirements. Washouts or sites of potential instability must be stabilised and protected. S8.8 Temporary closure Where roads and tracks are temporarily closed , they must be stabi lised, drained and left to revegetate to control soil erosion without the need for maintenance. 7 The TC signs are a collection of non-standard traffic control (TC) signs that have been "officially approved" (as required by the Transport Operations (Road Use Management Act 1995)). These signs have been designed for specialised use and designed to comply with the guidelines set out in the traffic and road use management (TRUM) manual and the manual for uniform and traffic control devices (MUTCD).

Code of practice for native forest timber production on the QPWS forest estate S8.9 Maintenance Access roads and tracks must be maintained to ensure a stable and good running surface , effective drainage and safe use. Road surfaces, crossings and drainage systems must be inspected sufficiently to ensure that they are functional , safe and in a stable state. All drains must be inspected thoroughly and repaired before the onset of the wet season and during and after periods of heavy ra infall. Maintenance techniques must: • return usable material to the pavement and avoid lowering the road surface in a way that impedes surface drainage or concentrates flow along the road edge ; • restore the road profile and smooth the road surface using compaction to strengthen, seal and preserve pavement life; • restore drainage systems including any erosion control devices; • ensure water can freely drain from the surface and is not blocked by vegetation or a berm unless the berm is used as part of the drainage system; • minimise or avoid disturbance to soils adjacent to the road; • avoid deposition of spoil or sediment into watercourses; • manage road-side vegetation to maintain safety and road-edge bank stability; • employ hazard warning devices while maintenance operations are in progress. 47 S8.10 Decommissioning Unless formally advised otherwise, roads that are no longer required for timber extraction and forest management must be stabi lised, rehabilitated , permanently closed (where appl icable}, decommissioned and allowed to regenerate as follows: • Recovery of materials is permitted provided it does not resu lt in material or serious environmental harm. Removal must not adversely impact on water quality and disturbed areas must be drained and stabil ised. • Watercourse crossings must be removed unless their presence does not pose a threat and/or removal will create greater damage than retention. • Crossing materials used for tempora ry access must be removed . • Bed and bank contours must be reinstated and stabilised . • Approaches must be drained and stabilised . • Where benefic ial in controll ing accelerated erosion , road surfaces must be levelled to avoid concentrations of water on or along the surface. Provide pronounced outslope , water bars or other cross drainage structures and prepare surface to stabil ise it against erosion, spread debris and encourage revegetation, naturally or artificially, without the need for maintenance. • Where barriers are to be instal led to prevent access to permanently closed roads, they must be placed in a safe and practical location . These roads are to be identi fied in the OHP. Code of practice for native forest timber production on the QPWS forest estate Schedule 9: Forest road and track drainage S9.1 General Roads and tracks must be provided with an effective drainage system, to meet normal rainfa ll events, and to maintain the load bearing capacity of the pavement, minimise soil erosion from either the pavement or drains, and minimise sedimentation of watercourses . W ithout accelerating soil erosion , an effective drainage system wi ll: • stop water from adjacent areas from flowing on to, or saturating , the pavement; • shed surface water from the pavement; and • collect surface and subsurface waters and divert th is away from the road . Drainage systems wil l consist of various combinations of : • catch drains to intercept and divert water from batters or the road; • a road profile , crowned, outsloped or insloped, that sheds water from the surface; • a drain network that takes shed and intercepted water away from the roadway and may include a system of table , turnout and cross drains; • breaches where berms prevent water shedd ing from the road; and • sediment traps or vegetated areas where water wil l decelerate and deposit sediment (Diagram 9). Diagram 9 - The basic road drainage system for A, B and C type formations. / /4 48 1' !; / Code of practice for native forest timber production on the QPWS forest estate S9.2 Basic principles All timber roads , tracks or snig tracks must use natural drainage where present, otherwise appropriate drainage must be constructed and maintained in an effective state during and after the completion of use. This can be achieved by applying the following: • Locate dra ins at critical locations such as : significant changes in slope or direction (a change of two grades of slope, as per Table 15); points of concentration of overland flow (refer also S3.8); and 1 Orn before any watercourse crossing or junction with another track or landing , or at the closest practical point where water can be diverted (refer also S10.6). • Drainage systems must provide protection for normal rainfall events . Variations to Table 15 may be appropriate in situations where the drainage system design is not sufficiently robust to accommodate normal flow events without damage, or this w ill result in less overal l environmenta l impact. • Location and outflow from drains must be carefu lly planned to avoid: causing accelerated erosion of adjacent land or watercourses because of inappropriate redirection of concentrated and increased water flow and velocity; accelerated erosion of unprotected fil l banks. • Drain profile must be consistent with soi l type and the avoidance of erosion . Flat bottomed drains should be used where erodibility is high . • Drains susceptible to scour because of soi l type, grade , water volume or ve locity must be suitably armoured using vegetation , rock or other materials. • Drainage design should ensure flow without scour (as per S9.3). • Drainage, where required, is constructed and spaced in accordance with Table 15. • Construct additional drains, where required, in addition to spacing requirements .

(4) Spacings for other combinations of grades can be determined from the full spac ing table in Native Forest Soil Protection. (5) Drain spacing and critical locations can be met from any drainage type or combination. • Drainage must discharge on to stable areas of undisturbed vegetation, a stable site, into debris or an energy dissipating structure and 49 not directly into watercourses or onto exposed soil or fil l slopes. Exposed soil or fill banks must be appropriately protected by Code of practice for native forest timber production on the QPWS forest estate vegetation , debris, flumes or other erosion control structures . • Drainage, at other than at a watercourse crossing, must not be discharged within the distance from WPZ specified in Schedule 3 Watercourse protection : landing and snig track drainage - 1 Orn road drainage - 20m • Discharge should aim to deposit suspended sediment before runoff enters a watercourse. • Outlets shou ld disperse water flow to lower velocity. Sediment traps or devices should be provided where necessary. S9.3 Drainage elements S9.3.1 Catch drains or diversion banks Catch drains and diversion banks are drains placed above cut batters to divert overland flow away from the road. Such drains should be gently graded and protected against scouring . They should be installed where: • water may flow onto the road ; and/or • unacceptable erosion of the road cutting surface is likely. S9.3.2 Road profile - Road pavements should be shaped to shed surface water to either both or one side of the road. The profile may involve a crowned formation, be outsloped or insloped. The crossfall grade should be in the order of 1 to 3 degrees to shed water w ithout causing erosion of the surface. The profile should be maintained by grading and compaction and ensure that edge berms or shoulder vegetation does not impede the shedding of water or cause longitudinal scour of the road surface . On flat bladed-tracks, maximum use should be made of natural cross fall or drainage. The surface should be maintained to assist cross drainage. 50 Berms along the edge of the track should be breached at the set drainage spacing intervals to allow water to drain from the road where suitable discharge conditions are available. Where suitable discharge is not available alternatives should be appl ied and documented. S9.3.3 Table drains - Table drains are drains at the side of and parallel to the road to catch and convey runoff water. Table drains must: • have a flat bottomed, 'v'-shaped or dished profile; • be built, where possible, at least 300mm below the level of the top of the formation at the outer edge of the shoulder; • set, where possible, at a gradient of 1 to 3 degrees to guarantee flow without scour. Where steeper grades or erodible soils are unavoidable, consideration should be given to providing a flat profile , vegetating or lining the drain to prevent scour; and • where table drains pass through box cutting and cannot be drained by turnout drains, steps must be placed at drainage spacing intervals to reduce drain gradient and dissipate water flow energy safely.

They must be built to ensure that: • in the absence of natural drainage, drains are spaced in accordance with Table 15; • the table drain is blocked at its junction with the turnout drain to ensure water does not bypass the turnout drain; • drain outflows have a fal l of 1 to 3 degrees, with a maximum 5 degrees, using a curved al ignment as necessary, to keep the flow to a non-erosive velocity; • drains have a 'v' shaped or flat bottomed profile. Flat bottomed profiles should be used where soils are erodible. Drain outflow must disperse water on to stable ground or vegetation ; and • drains do not directly enter watercourse protection zones but are diverted into surrounding vegetation in accordance with distances specified under watercourse protection in Schedule 3 and 9.2 . Where higher grades are unavoidable , the drain should be suitably protected against scour. S9.3.5 Cross drains - Cross drains must allow surface or table drain water to pass under or across the road pavement. Options include cu lverts, inverts and cross banks. In the absence of natural drainage, these must be bui lt to ensure: • cross drains are spaced in accordance with Table 15; • water does not bypass the drain ; • cross drain offset angle relative to the road direction as per Table 15; • cross drain outflows (tail ) have a fal l of 1 to 3 degrees, with a maximum 5 degrees, using a curved alignment as necessary, to keep the flow to a non-erosive velocity; • inverts and cross banks have a 'v' shaped or flat bottomed profile. Flat bottomed profiles should be used where soils are erodible. • drain outflow must disperse water on to stable ground or vegetation ; and • cross drains do not directly enter watercou rse protection zones but are diverted into surrounding vegetation in accordance with distances specified under watercou rse protection in Schedules 3 and 9.2. 52 Culverts - Culverts are pipe or box structures that allow water to be channelled under the road from one side to the other. In addition to the requirements for cross drains , the construction of culverts should ensure that: • any pipes or box cu lverts are installed to manufacturer specifications with attention to depth of fi ll (See also Schedule 8.2); • pipes must be set to have a fall of 1 to 3 degrees, be surrounded by compacted fill and have a cutoff wal l to prevent erosion under the pipes (Diagram 11 ); • culvert inlets and outlets are adequately protected to minimise erosion from flow entering or discharging from the drain. Head and wing walls must be constructed with concrete, logs or stone pitching. Outflows must be provided with a scour pad of concrete, stone or gabions ; • where cu lverts flow out over fill , adequate protection in the form of a flume, drop or hardened energy dissipating structure must be provided to ensure that water does not erode the fi ll; and • cu lverts have sediment traps using a sump or structure, e.g. logs or rock, to trap and slow water and permit settlement of sediment. Code of practice for native forest timber production on the QPW S forest estate Diagram 11 -Typical pipe culvert Inverts - Inverts are trafficable depressions in the road surface that intercept surface water and convey it across the road (Diagram 12). They are most suitable on lower grades (slopes). Inverts are built by excavati ng material from the road to form the drain. In some cases this material may be spread on the road surface down slope of the drain itself. In addition to the requirements for cross drains , the construction of inverts should ensure that: • size is adequate to match fl ow requirements ; and • the base of the depression is protected with rock if the wetness of the substrate makes th is necessary. 53 Code of practice for native forest timber production on the QPW S forest estate Diagram 12 - Inverts Invert (flat base) Cross banks - Cross banks are banks placed across the road surface to direct water across the road surface and reduce erosion by minimising the concentration of water along the road pavement and reducing runoff velocity. In addition to the requirements for cross drains (S9.3.5): (i) Rollover cross banks are used where the road or track is intended to be trafficable. They are constructed by excavation and/or deposition of material to create a long and gently sloped cross bank (Diagram 13). Excavation should not expose erodible subsoi ls. 54 Code of practice for native forest timber production on the QPW S forest estate Diagram 13 - Rollover cross bank example Rollove, cross bank (cross-section) ~~ Space according to the drainage table (i i) Water bars ('whoa boys') are steep cross banks that are used on roads and tracks that are not required to be easily trafficable . They are primarily erosion control structures best used to stabilise surfaces on the completion of use . Diagram 14 - Water bar example Earth mound 35 - 50cm above tracl< surface Offset water bar to road alignment Mound must slop runoff returning to track Water bars operate by slowing and diverting water from tracks to a stable outlet without water returning to the track down slope (Diagram 14). 55 Depth 30cm below ground level Code of practice for native forest timber production on the QPWS forest estate Water bars may be angled. From a line at right angles to the track's al ignment, offset the water bar to the angle indicated in Table 15 to allow flow, without scour, towards the outlet (Diagram 15). Diagram 15- Water bar offset angle Water Bar Offset Angle Water bars are generally constructed by excavating a flat-bottomed ditch using a shal low cut to avoid exposing erodible subsoi ls. On stable soils th is is excavated from the up slope side of the mound. On unstable soils the excavation can be on the down hill side or, alternatively, import soil to avoid excavation . Construction can involve a push along the road to excavate and build the mound before sweeping an outlet. Alternatively, a preferred practice is to sweep the outlet towards the road and deposit the spoi l on the road surface before sweeping and cutting along the road to complete the mound. The water bar should have an unconsolidated height of up to 50cm above the track surface (Diagram 16) to allow for an effective barrier after 56 settl ing. Mound height must be matched to the soi l type, terrain and management need to maintain effectiveness as fo llows: • smaller mounds are acceptable where: soils naturally pack or consolidate wel l and on low slope situations; or they assist natural drainage; • larger mounds (exceeding 50cm) may be required where: the soil is loose and wil l not read ily consolidate; or slopes are steeper; or more intensive use requ ires a higher water bar. Code of practice for native forest timber production on the QPWS forest estate Diagram 16 - Example of a typical water bar height and depth Typical Water Bar Height and Depth Use higher mound height on steeper slopes Mounds are best compacted during construction by walking the machine over the unconsolidated earth . Ensure that water will flow to the outlet, that the outlet is stable and disperses water to vegetated ground, and that outflow wi ll not return to the track downslope. Where water bars are used for road closure, tree heads and/or other obstacles should be pulled over the top of the mound where there is a risk of cattle trampling . Note: Where water bars are used to control points of concentration of overland flow, the water bar must not be constructed in or disturb the water-crossing point. A mound must be bui lt down-slope of the crossing point to ensure water cannot flow down the road. 57 Original surface S9.4 Silt traps Silt traps must be provided on turnout and cross drains where vegetated outlets are not available and suitable. The standard and permanency of such traps should reflect the road class with more elaborate and permanent structures or devices being placed on the major classes of roads (A, B and C type formations). The options inc lude: • Inlet sump - a sump can be provided on the inlet of cu lverts to catch sediment. This must be periodica lly cleaned to keep it operative. • Outlet device - the aim is provide a structure or device that will temporarily catch and retard water causing sediment to deposit. The options include: rock piles ; timber barrier; mesh sediment fence; and straw bales or debris. For unformed roads it may be appropriate to use natural drainage and use vegetated areas as si lt traps . Code of practice for native forest timber production on the QPWS forest estate S9.5 Stabilisation of washouts Washouts on roads are a source of significant sediment and can cause the road to become unsafe or impassable. It is fundamentally important that corrective action is taken as early as possible to reduce both the adverse impact and the scale and cost of corrective action. Minor washouts can often be simply corrected by compacted earthen fil l and appropriately drained. Where major washouts cannot be circumvented by existing alternative access, the fol lowing principles should be appl ied : • lining or armouring the head to stop headward advance ; and • lining or armouring the base of the washout below the head to prevent the washout base from deepening and causing further collapse. Where proposed remedial works vary from the above, expert advice must be sought. New road construction to circumvent washouts must be approved. Remediation may be achieved by: • Investigating the cause of the washout and seeking to correct this rather than try to armour the washout face . Usually this w ill involve redirection of the source of the water above the washout. This may involve a diversion drain or the instal lation of more cross drainage. After dealing with the cause of the washout the road or track surface must be re instated. • Correcting the drainage problem as described above, then protecting the washout head from further gullying action.

(International Erosion Control Association (Australasia), Picton , NSW). 58 Code of practice for native forest timber production on the QPWS forest estate Schedule 10: Timber harvesting practice S10.1 General The schedule sets out the minimum management requ irements for timber harvesting using ground based-extraction techniques. S10.2 Planning Harvesting must be planned to be safe and efficient with minimum loss of productive area and acceptable environmental impacts. Harvesting approach - The extraction system must use uphill snigging unless downhill snigging is the only safe , practical and least impact option (Diagram 17). The approach adopted must be Diagram 17 - Uphill and downhill extraction based on an analysis of safety, effic iency and environmental risk in the particular circumstances, including anticipated weather and ground conditions that prevai l. Equipment - All equipment used in all harvesting operations including fell ing , snigging , loading and hauling , must have an effective spark arresting exhaust system. Uphill (away from watercourses) and Downhill Extraction Systems Total impact - Planning must optimise efficiency and minimise total impact by balancing the impact of snig track length against landing numbers and locations and haulage road/track length and haulage. Planning must seek to: • use existing snig tracks , landings and roads where practical, relevant to machinery used and where consistent with Code standards; 59 • minimise the total area removed from production as a result of disturbance on landings (S10.6), and major and minor snig tracks (S10.4); and • minimise the number of watercourse crossings and locate them where they have the least environmenta l impact (Schedule 3). Code of practice for native forest timber production on the QPWS forest estate S10.3 Felling and crosscutting Felling may be carried out by using either a chainsaw or by a tree-fell ing machine. Felling must only be carried out by accredited operators. Felling practices must control the manner in which trees are felled to faci litate : • recovery by keeping the stump height as low as practical to maximise merchantable volume and to avoid stem breakage during felling , while giving due regard to safety; • extraction by integrating with and assisting the snigging operation to minimise the extent of snig tracks and/or the amount of mineral soi l exposure or compaction including tracked machine felling; • biodiversity protection by avoiding damage or disturbance to exclusion areas or species, special management zones and habitat trees , (refer also S6.3.6); • watercou rse protection by complyi ng with the watercourse protection requirements Schedule 3; and • forest productivity by minimising direct damage to retained crop or regeneration and by not accumulating excessive debris around the base of identified retained or habitat trees (refer also S6.3.6). 60 S10.4 Snig tracks Snig tracks must be designed and located to optimise safety and efficiency and to minimise loss of productive area, earthworks and soil disturbance. The snig track network must consist of the minimum necessary length and intensity of major and minor tracks. Major and minor snig tracks must be located and constructed according to specifications detai led in Table 16.

Table 15 spacings. 61 Code of practice for native forest timber production on the QPWS forest estate S10.5 Snigging Snigg ing machinery must be matched to the harvesting task and forest conditions . Preferred equipment includes: • crawler tractors equipped with wide tracks and integral arch winches; • rubber-tyred skidders , equipped with wide tyres and a grapple or w inch; • excavator-based harvesters ; and • forwarders . Because skidders generally cause less soil disturbance , they are preferred on slopes below 19 degrees particularly where erodibility is high . Crawler tractors should be used on steeper slopes for safety reasons. All snigging equipment must: • be capable of lifting one end of the log clear of the ground while snigg ing ; and • where equipped with a blade, have a blade type that is appropriate to the task. Machine operators must be trained and competent in machine use and snigging practice. Snigg ing practice must optimise efficiency and minimise soi l disturbance and water pollution. Snigging must minimise disturbance to remaining vegetation except where ground disturbance is silvicultural ly necessary. The snigging approach must be systematic to minimise the number and duration of tracks in use, and where possible, progress the snigging face in an uphi ll section so that the harvested areas are fu lly stabilised and drained before areas above are disturbed. Uphill snigging must be used where practicable (see S10.2). Machines must be operated to minimise the area disturbed , the intensity of soi l disturbance, damage to designated retained trees and essential regeneration . Operators of snigging machines must: • control speed; • use walk-over techniques wherever possible to maximise ground cover retention and minimise soil disturbance and mineral soil exposure ; • keep the blade raised while travelling ; • use reversing, log lifting or other techniques to minimise unnecessary ground disturbance including "tracked machine screwing"; • use winches, where appropriate, to pull logs from stumps where this will reduce track length or soil disturbance; • periodically alter the running track to minimise rutting or disturbance; 62 • not snig along the bed of any watercou rse; • not snig along any cattle pad likely to concentrate water flow; • comply with the watercourse protection measures (Schedu le 3); and • comply with operational restrictions (Schedule 18). Snig track drainage must be effectively maintained during snigging by surface smoothing and berm removal. Also apply temporary stabilisation measures to disturbed areas when: • machinery is removed from sites or operations that have ceased for more than two weeks; • there is a likelihood of an extended or high intensity rainfall event; and/or • there is an occurrence or likelihood of soi l loss due to snigging (refer also S10.8). On completion , tracks must be naturally or artific ially stabil ised and drained to avoid accelerated soil erosion , and/or degradation of water quality. Stabilise and, as necessary, drain snig tracks within two weeks of completion of track use. Other requirements include: • Temporary watercourse crossings are to be removed and rehabil itated; • Track surfaces are best smoothed to restore overland flow and covered with as much debris as is possible; • Where practical and where it wi ll not exacerbate damage or disturbance, edge berms, ruts or incisions should be smoothed to avoid confinement or acceleration of water along the track without increasing the track width ; • Place as much debris as is practical on the track surface to provide surface cover; • Where seriously rutted (ruts exceed 30cm in depth and continue for 10m or more) restore the track profi le by backfill ing or the placement of harvesting debris; Code of practice for native forest timber production on the QPWS forest estate • Construct cross drains only where necessary. Systematically consider progressive sections of the track over the distance specified for cross drainage spacing. At each potential drain location , cross drains must only be constructed if: The track surface is likely to erode because surface cutting , scalping or disturbance has exposed or loosened the soil over the spacing distance and existing debris, vegetation or living roots systems will not provide adequate surface cover and binding. Water w ill not drain naturally from the track with in the specified distance because of the: * absence of natural cross drainage; * absence of constructed cross fall; * absence of changes in track direction that wil l effectively deflect water; and * presence of berms or ruts that wi ll concentrate and confine water to the track. Cross drainage will general ly take the form of water bars but can also use inverts or other suitable structures. These must be constructed in accordance with Schedule 9 Forest Road and Track Drainage . Use of debris may be permitted in lieu of water bars where this is abundant and provided the density, placement and ground contact w ill achieve a result equivalent to a water bar. S10.6 Landings Harvest planning must ensure the best environmental and visual outcomes arising from the construction of the required landings and associated reading. Size and spacing The size and number of landings must: • provide for efficient and economic harvesting and haulage practices • provide for the safe and efficient storage , processing and loading of logs ; • provide for the quantity, length and type of products being handled; • be balanced to minimise the total area of clearing , including associated roading . The re lationship between landing size and distance between landings should be guided by the spacings given in Table 17. Table 17 - The relationship between landing size and distance between landings Maximum I Minimum Distance I 63 Landin~ Size between Landings (ml (ml 600 200 900 300 1000 350 1200 400 1500 500 1800 600 Where Forest Products proposes alternatives to Table 17 to achieve better environmental outcomes, approval from QPWS is required . Location Landing sites must be located and used under the following conditions : • Road sides can be used for log loading where this is safe, practical , can be drained and will cause less damage than the construction of a landing . Use must maintain road function and drainage. • Existing landings must be used where this wi ll result in less overall environmenta l impact than the construction of new landings. • New landings must only be constructed where essential and be located to optimise resource access and snig and haul distances. • Landings are best located: on stable, easily drained ridges or slopes not exceeding six degrees ; outs ide areas excluded from harvesting with drainage the prescribed distance from Watercourse Protection Zones (Schedule 3); and so that snig tracks can approach landings from below or provide for diversion drainage where snig tracks must approach from above. Construction Landing construction must ensure that: • landings are constructed in dry weather when soils are not wet or saturated ; • clearing is confined to the landing area; • debris is stacked , dispersed or disposed of: w ithout damage to trees marked or otherwise identified for retention with in the allowable boundary area; or to prevent a fire hazard for retained trees; • topsoil disturbance is minimised; • where topsoil is pushed up with debris, it must be positioned to allow machine access for respreading on completion of use; • earthworks are a minimum to that necessary to achieve a practical working area and avoid entry of soil or debris into exclusion areas; • cut and fi ll batters are set at a stable angle and protected with debris; and Code of practice for native forest timber production on the QPWS forest estate • runoff is managed by optimising natural drainage, and/or by constructing cross fall or diversion drainage. Use Operation of the landing must manage logs and debris to minimise damage to all trees marked or otherwise identified for retention. Damage to retained stems within the landing area shall not be considered as damage provided that the cleared area is smaller than the permissible landing size. Landings must not be bladed off to keep them operational. Excess bark must be used in track or landing stabi lisation. Stabilisation on completion of use All landings must be stabilised within two weeks of completion of use by: • removing all rubbish or waste materials; • providing surface drainage to prevent ponding or soil erosion including necessary surface smoothing, cross fa ll drainage, removal of berms or construction of diversion drains ; • constructing water bars on tracks , where necessary, to divert water flowing onto or from the landing into surrounding vegetation; care should be taken to ensure that the drains do not divert water back onto the landing at some other point (refer also S9.2); • spreading debris and associated topsoil mounds arising from construction of the landing , and debris from processing ; and • spreading any stockpiled topsoil evenly over the disturbed area. S10.7 Loading Loading of timber products must only occur at landings and must use equipment and techniques that are safe and minimise environmental impact. Wheel or tracked machines equipped with forks or a grapple are preferred for loading. Swivel loaders are preferred . Loading with a dozer and constructed earth ramps should be discouraged. Loading management must: 64 • maintain road access for essential traffic ; • avoid machinery impacts outside the landing area ; • conform to operational restrictions in Schedule 18; • maintain an effective level of area stabi lity and drainage, • manage debris to minimise a fi re hazard; and • stabil ise and drain the area immediately upon cessation or completion of use. S10.8 Haulage Haulage of timber must be safe and environmentally respons ible. Haulage must comply with operational restrictions in Schedule 18. Road drainage must be: • maintained in an effective state during use and any damage caused by the haulage operation must be repaired immediately; • temporarily stabi lised when: machinery is removed from the site; or extended or high intensity rainfall is likely; or accelerated soil loss due to wet weather has occurred or is likely to occur; • restored and stabilised with in two weeks of completion of use (refer also S10.5). Code of practice for native forest timber production on the QPWS forest estate Schedule 11: Timber product harvesting practice S11.1 General Wherever possible, harvesting of products other than round timbers must occur with, or in close association with, timber harvesting. This is to enhance silvicultural treatment and/or avoid reopening of areas with undesirable secondary soil disturbance, compaction or damage to regeneration. All saleable timber products should be systematica lly harvested in ful ly integrated operations , leaving the area to regenerate and develop until the next harvesting cycle. Re-entry into timber harvested areas must not occur during periods critical to the establishment of regeneration. S11 .2 General conditions Harvesting operations must: • be from outside exclusion zones; • not include habitat trees or habitat recruitment trees (refer also S6.3.3, S6.3.4, S6.3.5); • not include standing or fallen trees that are obviously an active habitat, breeding site or shelter for birds or mammals (refer to S6.4); • disperse harvesting wastes from operations within the general area to minimise the fire hazard and interference with other users ; and • mainta in or restore all pre-existing drainage and soil stabilisation measures, consistent with Schedule 9. 65 S11 .3 Specific product conditions Speciality pieces may be harvested from standing or fallen trees provided the health or habitat value of the parent tree is not affected . Harvesting of fallen timber for any purpose must retain a minimum of 10 percent of material on site. This may be increased where species' conservation requirements apply. Charcoal can be taken from fallen and standing trees . Bark may be taken from dead trees. Harvesting bark from live trees, e.g. tea tree, requires that: • no plant is cut down or mutilated ; • the minimum diameter of the tree is 15cm at breast height; • bark is not harvested from more than one third of the target species growing in the area in any one operation . Subsequent harvesting from the same area may only occur when removed bark has been replaced ; and • the cambium layer is not exposed or damaged during harvesting. Sandalwood must be harvested in accordance with Schedule 12. Code of practice for native forest timber production on the QPWS forest estate Schedule 12: Sandalwood harvesting Sandalwood, Santa/um lanceolatum, shrubs may be harvested subject to the following conditions . S12.1 Operational access Operational access must: • use existing tracks wherever possible. Tracks must be stabilised and drained in a manner consistent with the Code; • for off-road access, use walk-over practices, trample rather than push vegetation and avoid disturbance of the soil surface; and, • ensure watercourse crossings are consistent with Schedule 3. S12.2 Selective harvesting Selective harvesting must: • be restricted to slopes less than 25 degrees; • use rubber-tyred machines; • only harvest live sandalwood where the diameter at breast height exceeds 12cm and cutting of primary branches indicates that heartwood constitutes 50 percent or more of the branch diameter; • collect/gather any dead sandalwood • utilise all commerc ially viable material available from harvested shrubs , including roots , stumps, boles and branches; • avoid or minimise damage to retained vegetation; • be by pulling except where this poses a significant risk of soi l erosion or isn 't economically viable; • be consistent with watercourse protection guidelines. Sandalwood may be harvested within watercourse protection buffer zones provided : • machinery does not enter the buffer zone other than on a pre-existing track; • sandalwood are not pul led closer than 2m from a defining bank (Diagram 18); • sandalwood stems within 2m of the defining bank, or below the defining bank, may be harvested by cutting provided the bank is not unstable, 'u'-shaped , phys ically damaged by harvesting or will become destabilised by harvesting ; and; • where stems are removed closer than 2m from the defining bank the host tree must not be damaged. Diagram 18 - Sandalwood watercourse protection system Watercourse Protection System Cutting only permitted if bank stable and not physically disturbed Buffer Zone S12.3 Selective harvesting in specific Strategic Environmental Areas (SEA) 66 Harvesting area No sandalwood pulling within 2 metres of the defining bank Code of practice for native forest timber production on the QPWS forest estate In the following Strategic Environmental Areas (SEA): • The Gulf Rivers Strategic Environmental Area; • The Cape York Strateg ic Environmental Area; • Fraser Island Strategic Envi ronmental Area; • Hinchinbrook Island Strategic Environmenta l Area ; harvesting is to comply with the following: • For harvesting of sandalwood in a designated precinct within a Strategic Envi ronmental Area: no harvesting within Sm of the defining bank of a stream or lake ; only cutting is permitted (i.e. no pulling) between Sm and 4Sm from the defining bank of a stream or lake ; pulling is permitted between 4Sm and 9Sm from the defining bank of a stream or lake, provided a minimum spacing of 1 Orn is retained between harvested trees. • For harvesting of sandalwood in a Strategic Environmenta l Area : no harvesting within Sm of the defining bank of a watercourse; pulling is permitted between Sm and 9Sm from the defining bank of a watercourse, provided a minimum spacing of 1 Orn is retained between harvested trees . 67 Code of practice for native forest timber production on the QPWS forest estate Schedule 13: Harvesting and regeneration silviculture Harvesting and regeneration silviculture requirements have been incorporated into Core 8.3.2. 68 Code of practice for native forest timber production on the QPWS forest estate Schedule 14: Camping and processing sites S14.1 General conditions Timber harvesting camping and processing sites must be appropriately located and minimise adverse impact to the forest. S14.2 Specific requirements In addition to the general conditions , the following are also to apply. Conform to OHP requirements Camping and/or processing sites must: • be located: in an area with good natural drainage; not within a WPZ ; and not w ithin the visual range of a public ly frequented road. • have a clearly defined period of occupancy for processing sites ; • have drainage that is maintained in accordance with the requirements for landings under Schedule 10. Protect habitat Camping and/or processing sites must: • avoid or otherwise provide protection for any RE or threatened species as required; • minimise clearing and damage to trees or forest vegetation; • must not involve the insertion of spikes , nai ls bolts or similar into standing trees; Meet operational requirements Processing sites must be located to : • ensure snig distances to temporary processing infrastructure are a maximum of 500m; • ensure there is no truck haulage to temporary processing infrastructure (temporary mills ); • ensure processing wastes are progressively removed from the processing site and 69 red istributed throughout the forest or otherwise disposed of; • provide minimal necessary access Meet safety and hygiene requirements Camping and/or processing sites must: • have adequate fire protection including a bare earth fire break no greater than one blade width ; • have a waste disposal system that guarantees that wastes are collected, contained in appropriate bins and then disposed of properly; • provide for the proper storage and management of fuels , oils or hazardous substances in accordance with Schedule 17. Meet good site management practices Users of camping and/or processing sites must: • use caravans or temporary structures that are visually acceptable and do not diminish forest values or otherwise confl ict w ith forest management; • not bury rubbish (see Schedule 17) • locate lavatory, sullage and waste water facilities at least 40m away from any W PZ and in a location and soil type that will not contaminate surface or subsurface waters ; • maintain the site in a clean, tidy and fire safe condition. S14.3 Site decommissioning Site decommissioning must ensure : • structures and rubbish are removed ; • timber wastes are dispersed to assist rehabil itation and to avoid a fire hazard; • natural drainage is restored and necessary soil erosion control measures are provided; and • any additional requirements are met. Code of practice for native forest timber production on the QPWS forest estate Schedule 15: Pests and disease management S15.1 General Pests and diseases have the potential to cause signifi cant adverse economic, environmental and social impacts on State lands. Pests and diseases can spread naturally by wind , water or animals but also by human activities such as the movement of vehicles and equipment used by visitors, contractors and employees. Reproductive material can also be carried from one area to another on shoes and cloth ing. Materials such as soi l, mulch or gravel also have the potential to spread pest plant and pathogen reproductive material. Legislation relating to pests, weeds and disease management are specified in Core section 2.3.2.4. The movement of machinery presents a signifi cant contamination risk as there are many nooks and crevices where reproductive material can be lodged out of sight. If this is dislodged when a machine is next used, the new area can become contaminated . All persons entering State forest areas should take reasonable steps to reduce the risk of spreading pests through the movement of vehicles, plant, equipment, boats, persons, livestock and materials. DAFF Forest Products are to ensure, on a risk assessed basis, that machinery entering the harvest area is free from contamination . S15.2 Harvesting management Where possible, harvesting operations should be conducted in areas of the harvesting area where there are no known pests or weeds fi rst, and then move operations into infested areas. Inspection and mapping of known infestations is to occur prior to harvesting commencing . Pest infestations identified during harvesting are to be 70 managed according to these principles and progressive ly mapped on the harvest fi le . S15.3 Prevention of spread Harvesting operations are to be managed to restrict the further spread of any pest or disease infestation. Control measures must be consistent with the relevant legislation. The use of chemical control products must be in accordance with the manufacturer's specifications. S15.4 Clean-down facilities All machinery used in an infested area and likely to be contaminated with pest or disease reproductive material is to be cleaned prior to exiting the infested area or at a designated clean down site . Designated clean-down sites on the harvesting area are to be used to assist w ith future monitoring. Care should be taken when deciding the location of clean-down sites to reduce risk of spread and for ease of monitoring and control. All clean-down sites are to be located at least 50m from any watercourse to prevent contaminated runoff from entering watercourses. S15.5 Monitoring Harvesting operations w ithin the sale area and associated haul routes will be monitored for pest weed spread as required. Code of practice for native forest timber production on the QPWS forest estate Schedule 16: Air and noise pollution management Timber harvesting and associated activities must be managed to prevent or minimise unreasonable interference with any environmenta l or soc ial values as caused by smoke, dust, odour, noise or light. The potential for air pol lution and noise interference must be considered during planning where this is li kely. Strategies may include but are not restricted to: • restricting operations to defined weather conditions; • restricting the use of equipment and machinery during defined periods of time; • using buffers and setbacks; • orientating equipment to direct noise away from sensitive places ; • use of specially muffled equipment or other noise attenuation methods appropriate to an activi ty or type of equipment; • positioning operations away from sensitive places; • temporary restrictions on other forest users ; and • road watering or treatment to control a dust hazard near to sensitive places. 71 Code of practice for native forest timber production on the QPWS forest estate Schedule 17: Waste and hazardous materials management S17.1 General All persons involved in timber harvesting , including associated roading works , are responsible for waste and hazardous materials management for activities under their control. S17.2 Waste materials management To minimise the risk of land and water pollution, visual or other degradation from wastes generated during operations , harvesting and road works areas are to be kept as waste-free as practical. The following must apply: • waste management must conform to the Environmental Protection Act 1994; • all wastes including paper, packets, boxes drums, machine parts , wi re ropes or other materials, are to be continuously collected, contained in bins or other suitable receptacles and removed from the forest to an authorised disposal site; • wastes must not be stored within 40m of any WPZ; • no waste is to be buried in the forest; and • all waste should be removed regularly and must be removed upon completion of the sale. S17.3 Toxic or hazardous substance management The use of toxic or hazardous substances must be minimised wherever possible. Such materials proposed to be used, including materials such as herbicides, pesticides and ferti lisers, must be documented in the OHP. Toxic or hazardous substances must be secured, stored , used and disposed of according to label instructions and relevant legis lation to ensure health and safety and the protection of forest values. In all cases : • emergency and preparedness response procedures must be available on site and implemented for all classes of toxic or hazardous substances used. These procedures must be done in accordance with the Safety Data Sheet prepared by the manufacturer, which must also be available on site; • fuel trailers and storage, filling or clean-down areas must be located in a secure , fire safe location at least 50m from a WPZ; 72 • on-site storage of toxic chemicals in drums is not favoured. Where absolutely necessary, the storage area must be bunded to contain any leakage or spillage and to prevent it from contaminating the surrounding soil or from entering any watercourse or water drainage system. The bunded area should 110 percent of the capacity of the all vessels stored within the bund . Additional volume should be al lowed to account for rainfall events and fire control operations ; • pesticides must be used according to the manufacturer's directions and conform to the Agricultural Chemicals Distribution Control Act 1966 including the obtaining of necessary licenses or permits; • machinery and equipment must be maintained to manufacturers specifications so that leaks are minimised; and • waste toxic and hazardous substances must be handled in accordance with S 17 .1 . S17.4 Spills and leaks In the event of a toxic or hazardous substance spi ll or leak the standard below will apply. General For all spil ls and leaks : • any toxic or hazardous substance must be contained as soon as practicable. Clean up procedures must be promptly implemented accord ing to emergency and preparedness response procedures, and any wastes generated during the clean-up must be disposed of according to manufacturer's guidel ines and waste management requirements ; and • measures must be implemented to ensure the event does not occur again. Spills and leaks greater than 20 litres in a single incident Department of Environment and Heritage Protection must be informed as per the notification requirements of the Environmental Protection Act 1994. Spills and leaks less than 20 litres in a single incident Where there is the potentia l for material or serious environmental harm to occur, e.g. 15 litres of a pesticide spills into a stream that feeds the local water supply, Department of Environment and Heritage Protection must be informed as per the notification requirements of the Environmental Protection Act 1994. Code of practice for native forest timber production on the QPWS forest estate Schedule 18: Operational restrictions Operations must cease or be restricted for safety reasons or when infrastructure , forest values or environmental va lues are threatened by weather or ground conditions . S18.1 Felling Felling must cease where wind strength prevents safe or accurate directional fell ing or when ground conditions are unsafe. S18.2 Snigging Snigg ing in a harvesting section or area must cease when: • soils are excessively wet or saturated; • water is flowing down a track for more than 20m; • 'dry' watercourse crossings are flowing and a temporary cu lvert has not been installed ; • continued use would result in rutt ing deeper than 15cm below the original land profi le ; affecting more than 30m or 10 percent of the track length whichever is less ; and/or adversely impacting drainage or water quality. • continued use would require mud/soil to be bladed off, deeper than 15cm below the original land profile; affecting more than 30m or 1 O percent of the track length whichever is less ; and/or lowering the track to the extent that effective rehabil itation back to or near the orig inal profile is prevented ; and/or adversely impacting drainage or water quality. Any blading off on snig tracks must be a last resort and will require extra works to stabil ise, including use of vegetation , replacing bladed off materials in situ or from other sources . In all situations, effective rehabil itation must be guaranteed. S18.3 Loading Loading at landings or roadsides must cease when surface runoff is occurring or when water is ponded on the section being worked on and usage wi ll resu lt in excessive soi l disturbance and adverse impact. S18.4 Road construction and maintenance Roading construction and maintenance operations must cease when surface water is flowing on the road works . S18.5 Haulage or heavy machinery 73 Use of unsealed forest roads must cease when it is unsafe or road damage occurs or is likely to occur. Wet conditions Road use must cease when: • trucks cannot move unassisted along the road ; or • the road is excessively wet, water is ponded, or water is flowi ng on the surface of the road, such that: rutting greater than 15cm in depth below the road profi le occurs over a distance of greater than 20m, and/or the road surface drainage or water quality is adversely affected; and/or any damage wil l render the road unusable Any damage caused under wet conditions must be repaired prior to further use of the road. Use of roads is prohibited if the operator cannot guarantee timely restoration. Operator's vehicles or trucks caught by a sudden intense rainfall event, may leave the forest if it is safe and necessary to do so. In some conditions , a loaded vehicle may need assistance to start moving. Once moving it should be capable of proceeding unassisted. In some circumstances it may be more effective to tow the vehic le out rather than to attempt to drive out. Dry conditions Road use for timber haulage must cease when: • deep bulldust develops on the surface of the road, and continued use wi ll render the road unusable, however: trucks may be assisted to move along the road; any damage caused under dry conditions must be repaired as soon as conditions permit; ongoing use may occur where there is a lesser environmental risk, rather than providing an alternate route that w ill rapidly become simi larly affected. This must be documented. Code of practice for native forest timber production on the QPWS forest estate S18.6 Harvesting operations Occasional ly it may be requ ired to shift harvesting operations to another area for wet weather or other unplanned reasons . This is acceptable provided : • conditions at the new site wil l not resu lt in similar damage; • affected sections of snig tracks, road or landings are not rerouted; and • vacated areas are stabilised as soon as practical. 74 Code of practice for nat ive forest timber production on the QPWS forest estate Appendix 1: Acronyms and abbreviations BA basal area BZ buffer zone cm centimetres C Coastal dbhob diameter at breast height over bark (measured at 1.3m above ground level) ER erodibi lity rating ESFM ecologically susta inable forest management FPA featu re protection area/s FZ filter zone ha hectarels JRMP joint road management plants m metre/s m' square metre/s m, cubic metre/s MOU memorandum of understanding MUID management unit identifier NIA not appl icable NFPS National Forest Policy Statement 1992 DAFF Forest Forest Products is the State Government's business group responsible for Products the commercial management of State owned native forests and is part of the Department of Agriculture, Fisheries and Forestry.

It should be noted that vegetation is influenced by geology as well as water availabi lity and past and present management practices. Chemicals Rodenticides , insecticides, fungicides, herbicides. Clean-down, clean- The clean-down of vehicles and equipment is undertaken to stop the spread of pest down site (also weed seeds and vegetative material and contaminants. Various clean-down methods called 'wash-down') and types of equipment can be used to remove any carried weed seeds and/or vegetative material potentially capable of spreading pest weeds . Clearing Note: Clearing in the context of this Code does not have the same meaning as the term "clearing" under the Vegetation Management Act 1999. Clearing includes the removal of standing woody vegetation for the construction of roads, (permanent or temporary), landings , major snig tracks and camping and processing areas. Clearing does not include the removal of standing woody vegetation from existing, overgrown roads, tracks, major snig tracks and landings etc provided the woody vegetation to be removed consists enti rely of: (a) native tree species regenerating following any previous clearing disturbance : • that have not achieved 1 Orn in height; or . when there is less than 20 years since the last disturbance . or (b) introduced or pest species.

Ecologically The terms Ecologically Sustainable Forest Management (ESFM) and Sustainable sustainable forest Forest Management are based on the princ iples of ecologically sustainable management development and for the purpose of th is Code these terms are synonymous. (ESFM) Ecological Sustainable Development is development that improves the tota l quality of life, both now and in the future , in a way that maintains the ecologica l processes on which life depends. Objectives are: . To enhance individual and community well-being and welfare by following a path of economic development that safeguards the welfare of future generations; . To provide equity within and between generations; . To protect biological diversity and maintain essential ecological processes and life support systems. In particular with regard to the requirements of the National Forest Policy Statement 1992 for sustainable forest use: . Maintaining the ecological processes within forests (the formation of soil , energy flows and the carbon, nutrient and water cycles) ; . Maintaining the biological diversity of forests; and . Optimising the benefits to the community from all uses of forests within ecological constraints. Environmental Where a timber harvesting activity has any adverse effect, or potentially adverse harm effect, (whether temporary or permanent and of whatever magnitude, duration or frequency) on an environmental value, and includes environmental nuisance. Environmental Unreasonable interference or likely interference with an environmental value. nuisance Environmental The potentia l to cause unlawful environmental harm. threat Environmental A quality or physical characteristic of the environment that is conducive to ecological value health or publ ic amenity or safety; or .

Hollow, habitat tree A hollow is a cavity in a habitat tree that may be used for nests, roosts or dens by hollow-dependent fauna . This Code defines that a hollow must be 10cm or greater along the opening's smal lest axis. In the past, routine surveys of hollow-bearing trees in Queensland forests have generally used 10cm as a minimum size criterion. This minimum size of 10cm is also used to reduce the chance of selecting insufficient hollow depth . For further information, refer to Lamb, D., Lyon , R., Smith, A.
