Assessment Information [top]

Red List Category & Criteria: Critically Endangered B2ab(ii,iii) ver 3.1
Year Published: 2016
Date Assessed: 2016-01-11
Assessor(s): Solari, S.
Reviewer(s): Battistoni, A.
Contributor(s): Velazco, P. & Turvey, S.T.
Listed as Critically Endangered because its area of occupancy is probably less than 10 km², all individuals are in a single location (an "hot cave"), and there is continuing decline in the quality of the condition of this singular habitat. Roost site receives no form of official protection (Dávalos and Eriksson 2003) and it is open to unregulated human visitation. Also, the cave has resident populations of feral domestic cats that feed on bats (McFarlane 1997).

Population [top]

Population:This bat is uncommon to frequent (Genoways et al. 2005). The size of St. Clair’s colony appears to be very small, the only numeric estimate is that of Goodwin (1970) who reports only about 50 bats of this species in St. Clair.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Apparently, this species requires large caves with high humidity to roost (Genoways et al., 2005). This species is known from a single cave (Tejedor et al., 2005). This species is moderately to highly gregarious with cave colonies estimated at fewer than 100 individuals (Tejedor et al. 2005). It occurs in the same cave with Natalus micropus (Hoyt and Baker, 1980), and other species. It occurs in a very dry and arid area with xerophytic vegetation. Its biology is poorly known (Genoways et al., 2005). It is insectivorous (Nowak, 1999). It probably forages in rather cluttered vegetation and over relatively small home ranges (Tejedor et al. 2005).
Continuing decline in area, extent and/or quality of habitat:Yes

Threats [top]

Major Threat(s): This species’ only known roost site, St. Clair cave, receives no form of official protection (Dávalos and Eriksson 2003), and is thus open to unregulated human visitation. In addition, the cave has resident populations of feral domestic cats that feed on bats and rats of the cave (McFarlane 1997). Besides, this is a "hot cave", with poor ventilation and nearly constant high temperatures (26–40 C) and humidity (90%; Tejedor et al. 2005), therefore, slight changes on external conditions might have major impacts on the bat populations.

Conservation Actions [top]

Conservation Actions: Protected areas are needed for this species (particularly St Clair cave), as well as regulated access to the cave to prevent excessive visitations.
