Assessment Information [top]

Red List Category & Criteria: Vulnerable C1 ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Richards, G. & Pennay, M.
Reviewer(s): Lamoreux, J. (Global Mammal Assessment Team), Racey, P.A., Medellín, R. & Hutson, A.M. (Chiroptera Red List Authority)
Listed as Vulnerable because it is believed - inferred from its rarity across a well studied range - to have a population less than 10,000 mature individuals, and habitat loss within its range is likely to cause continuing declines of greater than 10% over three generations.

Geographic Range [top]

Range Description:This species is endemic to Australia, where it ranges from south-eastern Queensland through eastern New South Wales. The type specimen is supposedly from Norfolk Island, but it has never been recorded since (T. Reardon pers. comm.).

Population [top]

Population:It has only been recorded as scattered individuals, and they appear to be genuinely rare. There have been just 120 reliable records of this species since 1914. Its range is approximately 90% in New South Wales in areas that are well surveyed. This would suggest a population of less than 10,000 mature individuals (M. Pennay pers. comm.).
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species has been recorded from dry eucalypt forest and over rocky rivers in rainforest and wet schlerophyll forest habitats (Hoye et al. 2008), particularly in complex habitats (G. Richards pers. comm.). There is a record of a small colony in a house (T. Reardon pers. comm.). One generation is approximately 5-7 years (M. Pennay pers. comm.). Its call is very distinctive, and rarely recorded despite extensive survey (M. Pennay pers. comm.).

Threats [top]

Major Threat(s): This species is suspected to be threatened by habitat loss including harvesting of timber, coastal development, and possibly inappropriate fire regimes.

Conservation Actions [top]

Conservation Actions: The species has been recorded from a number of protected areas (M. Pennay pers. comm.). Further studies are needed into the distribution, abundance, natural history and threats to this species, particularly on the effects of habitat loss to it.
