Threats Threats to the Julia Creek dunnart are outlined in the table below (Woinarski et al., 2014). Threat factor Extent over which Evidence base rating threat may operate Predation by feral Severe Entire have been shown to prey ‘Cats cats heavily’ on this species (Lundie-Jenkins & Paine 2000; Kutt 2003; Burnett & Winter 2008; Mifsud & Woolley 2012), and numbers increased following control of feral predators (Mifsud 1999). Mifsud & Woolley (2012) reported 18 Julia Creek dunnarts in stomach contents of 199 sampled feral cats in the range area for this species. Predation by foxes Moderate Entire Recognised as a threat (Burnett & Winter 2008), and some direct evidence of predation (Kutt 2003), but none reported in stomach contents of 57 foxes sampled by Mifsud and Woolley (2012) Habitat Moderate Large There is some, but varied, degradation and correlative evidence resource depletion & Paine 2000; Smith due to livestock et al., 2007). Much of its and herbivores habitat is intensively grazed by sheep and cattle. Habitat change Moderate Moderate There has been wholesale due to weed change in habitat structure and invasion suitability associated with the spread of prickly acacia (Acacia nilotica) and other woody weeds (Lundie-Jenkins & Paine 2000). Increased fire Moderate Moderate There is some experimental frequency and evidence, suggesting mostly intensity increased predation pressure after fire (Qld DERM 2009). Dunnarts can survive direct effects of fire if there is suitable habitat to provide protection from predators; impacts of fire depend on the timing and severity of the burn (Qld DEHP 2013).
