Little is known of the area of occupancy, extent of occurrence, abundance, density or habitat use of the greater bilby (Macrotis lagotis) in the north of Western Australia. To seek broad collaborative agreement on a research agenda, the Western Australian Department of Parks and Wildlife hosted a workshop where research priorities were identified through a facilitated process. Five key areas for future research effort were identified: (1) refine survey methods, (2) improve understanding of habitat use, (3) improve understanding of the genetic structure of (meta)populations, (4) improve understanding of the threat posed by introduced predators and herbivores, and (5) improve understanding of how fire regimes affect bilby conservation. A conceptual model describing the main landscape components thought to be influencing distribution is used to reconcile existing knowledge, link research priorities for the bilby in the north of Western Australia, and guide the development of an integrated program of research. The broad nature of the priorities reflects the limited knowledge of bilbies in the north of the state; however, this research program provides an opportunity to increase knowledge to enact both species- and ecosystem-focused approaches to conservation, and potentially contributes towards the implementation of more dynamic conservation approaches for mobile species.

Baudin’s cockatoo, Calyptorhynchus baudinii, is a threatened forest black cockatoo species, endemic to the south-west of Western Australia. In this study we fitted tail-mounted satellite transmitters to two female Baudin’s cockatoos that had undergone treatment and rehabilitation at Perth Zoo and Kaarakin Black Cockatoo Conservation Centre to investigate the feasibility of satellite tracking this species. Both birds were released in Kelmscott, Perth, into an area frequently visited by a flock of wild Baudin’s cockatoos. Both telemetry units provided reliable datasets, with one bird moving ~250 km south from the release site. The success of this trial opens the way to address key objectives in the Forest Black Cockatoo Recovery Plan, including: postrelease survival of rehabilitated birds, flock movement, habitat use, and the identification of critical feeding and breeding habitat. Most importantly, it demonstrates that satellite transmitters can be successfully used to locate and track forest black cockatoo species, which are otherwise difficult to monitor.

Management of wildlife in habitats fragmented by urbanisation requires an understanding of a species’ habitat use. Known populations of the critically endangered western ringtail possum (Pseudocheirus occidentalis) are largely restricted to bushland remnants in rapidly urbanising areas of south-western Australia. Habitat use is thought to be driven by nutritional content, structure and connectivity of canopy vegetation. At the southernmost extent of the species’ range, habitat use is largely unknown, although it is expected to be different from previous descriptions due to differences in vegetation characteristics. We used VHF and global positioning system tracking collars to determine short-term home-range size, diurnal refuge use and night-time tree use of western ringtail possums in bushland remnants within Albany City. Possums had small home ranges (0.88 ha) that were negatively correlated with percentage canopy cover; used a variety of daytime refuges (predominantly dreys); and preferentially utilised marri (Corymbia calophylla) and jarrah (Eucalyptus marginata) at night. These results confirm that differences in habitat use among populations exist and suggests that the species is reasonably flexible in its use of habitat. Management of western ringtail possums needs to be population specific and will benefit from further examination of habitat use in the variety of occupied habitats.

SCUBA divers surveyed populations of juvenile Panulirus cygnus on limestone reefs at Seven Mile Beach and Cliff Head, Western Australia, between 1987 and 1989. Estimates of the density and size structure of populations of early-juvenile P. cygnus had high precision, but their accuracy was lower because visual surveys underestimated the population size. Nevertheless, these estimates may be useful indices of puerulus settlement and the growth, habitat use and population densities of juvenile P. cygnus. Puerulus settlement on collectors correlated well with natural densities of early juveniles on reefs. Densities of juveniles were at least three times greater at Seven Mile Beach than at Cliff Head. However, juveniles grew faster at Cliff Head than at Seven Mile Beach. The density of juveniles in reef ledges was twice that in caves; the density in caves was 10 times that on the reef face.
