Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Ong, P., Rosell-Ambal, G., Tabaranza, B., Heaney, L., Sedlock, J., Alviola, P., Alcala, E., Pangunlatan, L.M. & Balete, D.
Reviewer(s): Hutson, A.M., Racey, P.A. (Chiroptera Red List Authority) & Stuart, S.N. (Global Mammal Assessment Team)
R. inops is listed as Least Concern because it is widespread in the Philippines, occupies a wide elevation range and is locally abundant. It occurs in a number of protected areas, and although lowland populations have undergone declines due to deforestation of the forest habitat on which it is mainly dependant, a large part of forest within the higher part of the species elevation range is not significantly threatened.

Geographic Range [top]

Range Description:The Philippine forest horseshoe bat is endemic to the Philippines and has been recorded from Biliran, Camiguin, Catanduanes, Cebu (Paguntalan pers. comm. 2006), Leyte, Luzon [throughout the island (L. Heaney pers. comm.)], Mindanao [Agusan del Sur, Bukidnon, Davao del Sur and Surigao del Sur provinces], Negros, and Polillo islands (Heaney et al. 1998; Gomez in litt. 2007), where it is found from sea level to 2,250 m asl (Heaney et al. 1998).

Current Population Trend:Stable
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:R. inops is mostly dependent on primary forest (Heaney et al. 1998) where it is common to abundant in lowland and montane forest, and only rarely found in secondary forest and mossy forest (Heaney 1991; Heaney et al. 1998; Rickart et al. 1993). It has, however, been reported in disturbed forest on Negros and in orchards on Mount Makiling (Luzon) (Sedlock 2001) and from mossy forest at 1,800-1,950 m asl in Balbalasang, Kalinga province, Luzon (Heaney et al. 2005).

Threats [top]

Major Threat(s): This species has no doubt declined because of loss of its forest habitat, especially at low elevations. However, it has strong populations in montane forest, and these are much more secure, as habitat loss is less severe in these areas (L. Heaney pers. comm. 2006).

Conservation Actions [top]

Conservation Actions: R. inops occurs in a number of protected areas. There is a need for taxonomic research into geographic variation in distinctive characters (L. Heaney pers. comm. 2006).
