Population [top]

Population: This species has been recorded widely within Japan, but most of the localities are from lowland primary intact forest. It is likely that at one time the species was more widespread, but has now been restricted to primary forest enclaves in the face of human encroachment on its habitat. Within the forest patches where they occur, they are somewhat common.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: It occupies only primary forest, mainly at low-lying elevations. It roosts only in tree holes so is a microhabitat specialist. It is absent from many areas that lack large trees with hollows.
Systems: Terrestrial

Threats [top]

Major Threat(s): Deforestation of the evergreen old-growth forests in warm temperate regions, primarily for agriculture, conversion to conifer plantations, logging and infrastructure development for expanding human settlements, is a major threat.

Conservation Actions [top]

Conservation Actions: Some of the recorded localities are from protected areas. It is listed as Endangered (EN) in the Japanese Red List (2007).
