Recent initiatives in biodiversity conservation in grazed temperate grasslands and woodlands in Australia
Considerable efforts are being devoted to conserving biodiversity within grazed temperate grasslands and woodlands in southern Australia.These efforts include : legislation to prevent further clearance of remnant vegetation, protection of high quality woodland remnants in formal reserves on public land and under property agreements on private property, land purchase and purchase of development rights, and a range of educational and incentive programs to encourage landholders to implement biodiversity‐sensitive grazing strategies.The major threats to biodiversity in grazed grasslands and woodlands are soil fertilisation, ploughing/tillage and conversion to non‐indigenous pasture species and crops, heavy set stocking, irrigation, and habitat fragmentation resulting in small, isolated populations.Increasingly, attention is being devoted to identifying circumstances in which continued grazing can play a positive role in maintaining biodiversity within conservation areas (especially in degraded ecosystems) and to developing strategic grazing regimes to promote native perennial species above exotic annual species in native pastures.Conservation approaches have shifted from a focus on protected areas to conservation through active use,with market access providing the incentive.Considerable research and development is required on all of these issues.
