AO7.2 Clearing within 100 metres of the defining bank of any natural wetland: does not occur within 50 metres of the defining bank of any natural wetland; and does not exceed widths in table 16.3.1 in this code. OR AO7.3 Where clearing cannot be reasonably avoided, and clearing has been reasonably minimised, an offset is provided for any acceptable significant residual impact from clearing of vegetation associated with a natural wetland (matter of state environmental significance). Clearing associated with wetlands (necessary to control non-native plants or declared pests, encroachment, thinning, fodder harvesting) PO8 Clearing maintains vegetation associated with a natural wetland to protect: bank stability by protecting against bank erosion water quality by filtering sediments, nutrients and other pollutants aquatic habitat; and terrestrial habitat. Clearing necessary to control non-native plants or declared pests: AO8.1 Where clearing is necessary to control plants or declared pests, mechanical clearing does not occur within five metres of the defining bank of a natural wetland. AND AO8.2 Clearing only occurs: within a 1.5 radius from the base of the stem of individual non-native or declared pests; or to the extent necessary to provide access for the control of the non-native plants or declared AND AO8.3 Clearing for access tracks running parallel to a natural wetland is not to be located within 10 metres of the defining bank of a natural wetland.

water holding capacity, soil structure, organic matter, soil biology, and nutrients, within or outside the land the subject of the development application. AO20.2 The local government is the assessment manager for the development application. Note: For guidance on developing a sediment and erosion control plan, please refer to the Best Practice Erosion and Sediment Control Document, IECA, 2008. Soil erosion (necessary to control non-native plants or declared pests, thinning, encroachment, fodder harvesting) PO21 Clearing does not result in: accelerated soil erosion – including, but not limited to - mass movement, gully erosion, rill erosion, sheet erosion, tunnel erosion, stream bank erosion, wind erosion, or scalding; and any associated loss of chemical, physical or biological fertility – including, but not limited to water holding capacity, soil structure, organic matter, soil biology and nutrients, within or outside the land subject of the development application. Clearing necessary to control non-native plants or declared pests: AO21.1 Mechanical clearing retains 50 per cent of the ground cover (dead or alive) in each 50 by 50 metre (0.25 hectare) area. AND AO21.2 New access tracks to gain access to a plant or declared pest infestation do not exceed five metres in width or de-stabilise the banks of any watercourse or drainage feature as a result of crossing, construction or use. AND Clearing for thinning: AO21.3 Mechanical clearing does not: occur in a regional ecosystem in table 16.3.6 of this code that states ‘mechanical thinning not permitted’; disturb more than 50 per cent of the ground surface or result in any hectare less than 50 per cent ground whether dead or alive; and on slopes in excess of five per cent.
