The northern quoll (Dasyurus hallucatus) is one of the numerous mammal species that has undergone a rapid decline across northern Australia in recent decades. The smallest of the quolls (yet still the largest marsupial predator in the northern Australia) they are adaptive generalists, able to live in a variety of habitats and consume a varied diet. However, the combined threats of cane toad invasion, feral cat predication and habitat loss from altered fire regimes has largely restricted this species to rugged and rocky ecosystem. Populations that do still persist in savanna woodland are at a much higher risk of extinction. On the Cape York Peninsula, northern quolls were formerly widespread and common. However, following cane toad invasion in 1980s, the quoll was thought to have become extinct in the region. It wasn't until a population was rediscovered at Weipa in 2013 that it was confirmed that they were still in the region. In response to this discovery, an extensive survey effort was undertaken and a further two nearby populations were found in nearby savanna woodlands. My Phd aims to focus on these populations to explore the factors that cause northern quolls to be susceptible to extinction n savanna woodlands by investigating how northern quolls use the habitat, how they interact with feral cats and dingoes, and how fire influences these behaviors. I am evaluating, long-term, coat-effective management options for the northern quoll.
