Assessment Information [top]

Red List Category & Criteria: Endangered A3c ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Velazco, P. & Aguirre, L.
Reviewer(s): Medellín, R. (Chiroptera Red List Authority) & Schipper, J. (Global Mammal Assessment Team)
Listed as Endangered because of a serious population decline, estimated to be more than 50% over the last 10 years, inferred from land-use changes (as estimated from satellite imagery), observed shrinkage in distribution and rapid habitat destruction and/or degradation which will likely increase in the next 10 years.
Previously published Red List assessments:
1996 Vulnerable (VU)

Population severely fragmented: No

Habitat and Ecology [top]

Habitat and Ecology: This bat is basically frugivorous. Although well collected the ecology of the species is poorly known.
Systems: Terrestrial

Threats [top]

Major Threat(s): The choco region is being rapidly converted to agriculture which poses a serious threat to this restricted species. Illicit crops are a problem and habitat is rapidly being converted to coca for drug trade. Aerial spraying of defoliants may also be a threat.
