Biodiversity Fund round one project

This project is seeking to connect three areas of high biodiversity value in the eastern and north-eastern rangelands of South Australia to reduce current goat and rabbit populations. Controlling the capacity of these pest species to move through the landscape will enable sustainable natural regeneration of a large area of high conservation perennial vegetation.

Two years of high rainfall have improved land condition in the area but have also created ideal conditions for pest animal species to rapidly increase and move across the landscape. The project will leverage from a landholder-based model of invasive species control to fill the gaps between existing landholder groups, thereby creating a larger connected area of land with improved range land condition.

The project will be centred on chenopod shrublands, mallee and grassland vegetation of the Bimbowrie, Caroona Creek and Pualco Range conservation parks, and surrounding pastoral properties in the South Australian Murray-Darling Basin and South Australian Arid Lands regions.

What will be achieved?

Short-term outcomes will focus on engaging landholders and coordinating control activities to deal with the rapid spread of invasive species.

Long-term outcomes will restore land condition between three high value conservation areas through improved partnerships to reduce grazing pressure in strategic areas.

Specific outcomes

  • A larger coordinated invasive species control program, built from combining three separate control programs driven by private landholder action groups.
  • Reduced grazing pressure on important rangeland habitat, including six threatened ecosystems.
  • Reduced threat to species of conservation significance, including nationally listed yellow-footed rock wallaby, thick-billed grasswren, needle wood, slender bell-fruit and silver daisy bush.
  • A larger buffer area around high biodiversity areas, where introduced herbivores are controlled using a coordinated and integrated approach.
  • Reduced spread of introduced herbivores between conservation and productive land.
  • Connectivity of three areas of high conservation value with improved land condition in productive adjoining rangelands.
  • Increased capacity of landholders and organisations to reduce the impacts of introduced herbivores at a landscape scale and in the long-term.
  • Sustained vegetation regeneration and long term improvement in carbon sequestration across the landscape with the potential for future carbon market programs in the rangelands.
