Habitat and Ecology:This forest floor species is historically associated with coastal forests, but can also be found in mid-montane tropical moist forest. On Mindoro, it has been found in secondary growth forest adjacent to primary forest.

Threats [top]

Major Threat(s): Continuing deforestation is the major threat to this species. Most coastal forests, a major part of the species' habitat, have been destroyed over the past 100 years.

Conservation Actions [top]

Conservation Actions: It is found in a number of protected areas and forest reserves in Luzon. There is an urgent need to preserve any remaining areas of coastal forest habitat. Further research is needed into the distribution, natural history and conservation status of this species.
