12 13 LOCAL HOTSPOTS

Biodiversity hotspots are a prior- ity for conservation. They are reservoirs of life and are the last remaining ‘jewels in the crown’. There is an urgent need for us to target our on-ground con- servation efforts towards local biodiversity hotspots in the West Corurgan area. By getting the biggest bang for our buck we can ensure as many individuals and species as possible benefit from our efforts. We can increase the wildlife carrying capacity of these HOTSPOTS: Sandhill Woodland in the Savernake/Berrigan/Mulwala region, such sites and expand the area of the as Wahgunya and Berrigan State Forests, and any stands of Boree Woodland. sites by improving and creating habitat adjacent to them.

The local biodiversity hotspots identified here are characterised by at least one of the following at- tributes: relatively large patch, high habitat diversity, high number of species, high number of threat- ened or locally endemic species, high productivity/fertility or a severely depleted vegetation type. Different vegetation types support different suites of wildlife. Con- servation of all vegetation types across the West Corurgan region is therefore very important. HOTSPOTS: Grassy Box Woodland found in Kentucky, Lonesome Pine, Ringwood Tank, Palmer and Coreen State Forests, as well as Goombargana Hill and other
