Geographic Range [top]
Range Description: This species is restricted to Mt. Isarog, Camarines Sur province, Luzon island (Philippines) in elevations between 1,350-1,750 m asl (Heaney et al. 1999; Rickart et al. 1991). Recent surveys of Mt. Labo and Mt. Malinao failed to detect the species (Heaney et al. 2016).

Habitat and Ecology [top]
Habitat and Ecology: This species occurs in primary montane and mossy forest. Most records of this species are from 1,350 m to 1,750 m (Balete and Heaney 1997, Heaney et al. 1999, Rickart et al. 1991). The holotype is recorded as being from approximately 750 m, which is in upper lowland forest (Musser 1982). The species is active both diurnally and nocturnally, and feeds predominantly on earthworms and soft-bodied invertebrates (L. Heaney and D. Balete pers. comm).
Systems: Terrestrial
Threats [top]
Major Threat(s): The population is restricted to a small but relatively stable area (Heaney et al. 2016). It is potentially threatened by habitat destruction (Heaney and Utzurrum 1991) and human disturbance due to rebels activities. The situation has improved somewhat since the 1980s, and the forest is regenerating. But at lower elevations, especially below 1,000 m the area heavily impacted by small scale farming and illegal logging. The upper elevational range of the species is only barely affected by human activities (L. Heaney pers. comm).
Conservation Actions [top]
Conservation Actions: The known range is entirely within Mt. Isarog National Park. The protection level in the park is variable, with the lower elevations, especially below 1,000 m, heavily impacted by small scale farming and illegal logging. Surveys which focus on high elevations should be done on Mt. Malinao and other peaks on the southern peninsula of Luzon (Heaney et al. 2016).
