Ecological function and introduced species, with Dr Arian Wallach
Dr Arian Wallach is an ecologist and Australian Research Council Future Fellow at Queensland University of Technology. Her work looks at how introduced species and apex predators like dingoes shape ecosystems, and how our values shape the way we study and manage wildlife. For several years she has been researching the wild donkeys at Kachana Station in the Kimberley, where Chris Henggeler and family have been restoring degraded country for more than 35 years. The episode covers: The role donkeys and cattle have played in soil, water, plant and fire cycles at Kachana Station The a-ha moment that drew Arian to consider donkeys’ role in reducing the impact of fire at Kachana Why donkeys might be fitting into an ecological niche that’s been empty since the extinction of giant wombats How we can think about the choices that land managers are making across farming and conservation. It’s a thought-provoking conversation, and Arian enjoys challenging some long-held scientific beliefs in her field. Links and resources: Arian’s review of evidence that foxes and cats cause extinctions of Australia's endemic mammals Kachana Station’s Wild Donkey project Eli’s reflections from a recent visit to Kachana Station More about desert donkey wells (or ‘ass holes’ as Arian calls them!) We hope you enjoy this conversation as much as we did.
