Population Trend: Decreasing

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.

Conservation Actions: Although it occurs in protected areas there is no enforcement in place.
