Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Kingston, T. & Meijaard, E.
Reviewer(s): Hutson, A.M., Racey, P.A. (Chiroptera Red List Authority), Chanson, J. & Chiozza, F. (Global Mammal Assessment Team)
Justification:
Listed as Near Threatened, although it is widespread, there is significant deforestation occurring at a rapid rate throughout its range. It seems to be a naturally uncommon species, and its preference for primary forest means it is particularly susceptible to loss of its habitat. Its populations are likely to decline by close to 30% over the next 15 years due to habitat loss making it close to qualifying for Vulnerable under criterion A3.
