My research examines mammal species persistence in the north Kimberley of Western Australia. The future of northern Australia’s mammals is currently uncertain, as recent studies have identified dramatic declines in species from a range of ecological backgrounds, and within well resourced national parks. In Kakadu National Park, monitoring between 1996 and 2009 detected a 75% decline in the abundance of small and medium size mammals. If current trends continue the region could suffer multiple extinctions within the next twenty years. The Artesian Range in the north Kimberley is one of the few remaining parts of northern Australia where diverse mammal populations still persist.
My research asks;
Why do mammal species persist in the Artesian Range?
How can we best manage the land for conservation?
In addition to examining the threats to mammal species in the region particularly with respect to fire, we will examine the genetic connectivity of populations across the landscape. By examining gene flow within the range, and between different regions of the Kimberly, we hope to give greater context to mechanisms contributing to species persistence in the region.
