Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): McKenzie, N., Pennay, M. & Richards, G.
Reviewer(s): Lamoreux, J. (Global Mammal Assessment Team), Racey, P.A., Medellín, R. & Hutson, A.M. (Chiroptera Red List Authority)
Listed as Least Concern in view of its wide distribution, occurrence in a number of protected areas, tolerance of a broad range of habitats, large population, and because it is currently unlikely to be declining fast enough to qualify for listing in a threatened category.

Habitat and Ecology [top]

Habitat and Ecology:This species is known from a wide variety of habitats, including urban areas. It roosts in small groups in tree-hollows, building ceilings, and similar habitats. Maternity colonies can consist of several hundred animals (Rhodes and Richards 2008). Females give birth to a single young. Generation length is likely to be at least five years (N. McKenzie pers. comm.). The species moves northwards in the southern winter.

Threats [top]

Major Threat(s): There appear to be no major threats to this species in the short term. Global warming may be a serious threat to this species in the future because the species is tied to temperate Australia - in 70 years, the species' range is expected to have disappeared from south Australia (N. McKenzie pers. comm.).

Conservation Actions [top]

Conservation Actions: This species is known to occur in a number of protected areas. Further studies are needed into possible threats to this species.
