Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Sampaio, E., Lim, B., Peters, S. & Pineda, W.
Reviewer(s): Medellín, R. (Chiroptera Red List Authority) & Schipper, J. (Global Mammal Assessment Team)
Listed as Least Concern because although apparently uncommon, this species is widely distributed and tolerant to some degree of habitat disturbance. It is unlikely to be declining at a rate which would qualify it for inclusion in any threat category.
