Dominican Myotis is listed as Vulnerable. It is known from three locations on two Caribbean islands (Dominica and Guadalupe). Its extent of occurrence is around 6,000 km², but it is not found throughout the islands it inhabits, so the real distribution is smaller than expected for the size of the islands. Its habitat is declining due to expansion of human activities and also, hurricanes and severe weather could decrease local populations.

Geographic Range [top]

Range Description:This species occurs in Dominica and Guadeloupe islands (Simmons 2005).
Countries occurrence:
Dominica; Guadeloupe
Additional data:
Number of Locations:3

Population [top]

Population:There is no information on population, although a decline is suspected because of the low number of known localities and the effect of habitat loss and tropical hurricanes over these Caribbean islands.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species is poorly known. It is insectivorous (Nowak 1999). On Dominica, it was found near banana groves, open vegetable plots, as well as near coconut groves near a small riparian stream and grazed pastures, but also was observed in caves in clusters of 200-300 individuals (Genoways et al. 2001).

Continuing decline in area, extent and/or quality of habitat:Yes

Threats [top]

Major Threat(s): This species is not found throughout the islands it inhabits, so the real distribution is smaller than expected for the size of the islands. Recent surveys have found them strongly associated to caves and small creeks, that could be threaten by expansion of human activities. Also, severe weather (hurricanes) is not uncommon on these Caribbean islands, and may diminish local populations.

Conservation Actions [top]

Conservation Actions: Research actions are needed in regard to the knowledge of diurnal roosts (location, number of individuals on each, habits, and life cycles).
