The Landscape Context Planning system provides a landscape approach to biodiversity management in Tasmania's public production forests.
The Landscape Context Planning system is a geographic information system-based system developed by Sustainable Timber Tasmania that uses mapped information on forest type, harvest boundaries and forest zoning, to inform, implement, and monitor habitat retention and coupe dispersal decisions. The Landscape Context Planning system provides field planners with the tools to take a landscape approach to biodiversity management.
While the Landscape Context Planning system can be applied at any scale (e.g., local, forest block, or regional), our planners are mainly using the system to determine and report on the areas of forest that have been, or will need to be, set aside from harvesting for the long term within a one-kilometre radius of a coupe’s centre.
The system accounts for all existing retention in the landscape, including set-asides for wildlife habitat strips, streamside, skyline and/or biodiversity reserves, as well as formal reserves on public land under the Nature Conservation Act.
We are using the Landscape Context Planning system to achieve compliance against two key objectives for clearfell and aggregated retention operations in native forest on Permanent Timber Production Zone land. The objectives are to:
- Provide for mature (existing and/or potential) habitat at the local landscape level by requiring long-term retention from harvesting of at least 20 per cent of the public native forest within a one-kilometre radius surrounding the centre of each clearfell and aggregated retention coupe.
- Limit the concentration of harvesting in local landscapes, and potential effects on biodiversity, visual amenity, bushfire risk, soils, water quality, and water flow by ensuring that no more than 50 per cent of the public native forest within a one-kilometre radius surrounding the centre of each clearfell and aggregated retention coupe is less than five years old at any one point in time.
The Landscape Context Planning system includes a set of analytical tools to assist planners in adjusting the location and extent of harvest operations in order to meet these objectives.
Sustainable Timber Tasmania reports against these objectives in its Annual Report available from the Publications page.
