Native grasslands in northwest Tasmania and the role of forest managers in their conservation and management
Grassy ecosystems are amongst the most threatened ecosystems in southeastern Australia, with over 95％ of their area lost or severely modified in 200 years of European settlement.Native grasslands cover about 6500 ha in montane areas of Northwest (NW) Tasmania‐with an altitude range of 600‐1200 m.They include some of Tasmanias largest and most diverse grasslands.Most of the grasslands are dominated by Poa labillardierei (tussock grass), and are maintained by fire, frost and browsing by native animals.They occur in a mosaic with moorlands, peatlands, rainforests, native eucalypt forests and timber plantations.Tenure comprises formal reserves (e.g.National Parks), other public land ( mainly State Forest), and private land, including about 2000 ha owned by Tasmanias largest timber company (Gunns Forest Products).This paper describes how cooperative studies and active management, involving government agencies, researchers and forestry companies, have improved the conservation of grassland communities and species.It also discusses the evolution of management tools, and the role of legislation, education and industry certification in encouraging grassland conservation.
