Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Rosell-Ambal, G. & Tabaranza, B.
Reviewer(s): Hutson, A.M., Racey, P.A. (Chiroptera Red List Authority), Chanson, J. & Chiozza, F. (Global Mammal Assessment Team)
Listed as Near Threatened as its extent of occurrence is larger than 20,000 km², although it is uncommon and is thought to be in decline probably at a rate close to 30% over the next fifteen years primarily due to ongoing loss of its cave habitat. Almost qualifies as threatened under criterion A2.

Geographic Range [top]

Range Description:This species occurs from Borneo, Balambangam (Nor 1996) and Banggi islands, to the Philippines. It probably occurs throughout the Philippines; there are records from Cebu (L. Paguntalan pers. comm. 2006), Guimaras, Luzon (Rizal Province and Mount Makiling between Batangas and Laguna provinces (N. Ingle pers. comm. 2006)), Marinduque, Mindanao (Lanao del Norte Province, and Zamboanga Province), Negros, Palawan, Polillo and Tawi-tawi (Hollister 1913; Lawrence 1939; Taylor 1934; Heaney et al. 1998).

Population [top]

Population:This is an uncommon species, which occurs in caves or their immediate vicinity (Heaney et al. 1998). On Palawan Island, the species was captured in small numbers in caves (Esselstyn et al. 2004), while surveys on Luzon failed to capture the species and it is considered uncommon there (J. Sedlock pers. comm. 2006). The population is thought to be in decline.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:In the Philippines the species has been recorded roosting in caves near sea level (L. Heaney and R. Utzurrum unpubl. data) and foraging over freshwater, rivers and in agricultural areas.

Threats [top]

Major Threat(s): Cave disturbance is a major threat to the species. In the Philippines, caves can be blocked for example in Misamis Oriental, where the species was once abundant (Warguez pers. comm. 2006), on Negros caves are disturbed by guano miners (L. Heaney pers. comm. 2006), they are dammed in other areas, and on Cebu large numbers of people partake in unregulated spelunking and often open up new areas to the sport.

Conservation Actions [top]

Conservation Actions: This species occurs in a number of protected areas. Better regulation of cave use is required for this uncommon and cave dependent species, and comprehensive surveys of populations are required.
