Research priorities

Table 6 shows listed taxa, ordered by decreasing Action Score from the modified Millsap et al. (1990) system (see Appendix B).

High scores reflect lack of knowledge about and lack of conservation management of taxa.

Within the 'Critically Endangered' category, further research is needed for Gilbert's Potoroo Potorous gilbertii (underway) and Boullanger Island Dunnart Sminthopsis griseoventer unnamed subspecies (no detailed work current).

Within the 'Endangered' category, several taxa need additional research. In order of score these are: Kakarratul (Notoryctes caurinus), (no work underway) Itjaritjari (N. typhlops) (no work underway), Ampurta (Dasycercus hillieri) (some work underway), Kangaroo Island Dunnart (Sminthopsis aitkeni) (no work underway), Sandhill Dunnart (S. psammophila) (no work underway), Dibbler (Parantechinus apicalis) (work underway), Spotted-tailed Quoll (N Qld) (Dasyurus maculatus gracilis) (no work underway), and Julia Creek Dunnart (Sminthopsis douglasi) (limited work underway).

Within the 'Vulnerable' category several taxa have very high action scores. Work on these is urgent, since further research may clarify conservation status. In some cases these taxa may be more seriously threatened than currently thought; in others, further research may show that no conservation action is required. Priorities include Butler's Dunnart (Sminthopsis butleri), Southern Brown Bandicoot (Cape York) (Isoodon obesulus peninsulae), Black-footed Rock-wallaby (W Kimberley) (Petrogale lateralis western Kimberley race), Carpentarian Antechinus (Pseudantechinus mimulus), Golden Bandicoot (mainland) (Isoodon auratus auratus), and Fluffy Glider (Petaurus australis unnamed N subspecies).

Continuing and expanded research into threatening processes that affect several species is also urgent. Research into the effects and the control of the European Red Fox (Vulpes vulpes) in WA has led to improvements in the conservation status of several marsupials. Research into the control of Feral Cats is underway in parts of Australia; however, further research into and control of cats is urgent. Research into the effects of changed fire regimes and the development of fire regimes appropriate for marsupial conservation is also urgent, especially in grasslands and savannas, but also in forests, woodlands and shrublands.

Taxonomic research priorities are discussed in 'Introduction'.
