Assessment Information [top]

Red List Category & Criteria: Vulnerable A2c ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Soriano, P. & Molinari, J.
Reviewer(s): Medellín, R. (Chiroptera Red List Authority) & Schipper, J. (Global Mammal Assessment Team)
Listed as Vulnerable because of a population decline, estimated to be >30% over the last three generations, inferred from exploitation of maternity caves, and habitat destruction and degradation. Reproduces in a very limited number of caves and is vulnerable to vandalism. Lives in a very limited habitat type which is disappearing rapidly.
Previously published Red List assessments:
2000 Vulnerable (VU)
1996 Vulnerable (VU)
1994 Insufficiently Known (K)
1990 Vulnerable (V)
1988 Vulnerable (V)

Habitat and Ecology [top]

Habitat and Ecology: This bat roosts in caves and mines, often in colonies of several thousand. It emerges about an hour after sunset to feed on nectar and pollen. It lands on the flowers or may hover for short periods to feed. Night roosts, including buildings, are used after feeding (Reid, 1997). Asociated with thorn scrub with columnar cactus and Agave plants (Soriano and Mantilla pers. comm.). The ecosystem is rare and dispersed throughout its range. This species is "keystone" in its ecosystem as a pollinator and seed disperser of agave and cactus (and other plants associated with the habitat type). The species is migratory and colonies are sexually seperated. Breeds on islands and resricted to specific breeding caves.
Systems: Terrestrial

Threats [top]

Major Threat(s): Conversion of the ecosystem, which is rapidly being developed. Narrow range of habitat type, which is coastal - where much human expansion is occurring. Caves are very specific and threatened by vandalism. Maternity colonies are extremely vulnerable.

Conservation Actions [top]

Conservation Actions: Needs conservation of maternity caves and habitat type.
