Geographic Range [top]
Range Description: This species is known only from the islands of Salebabu (95 km²) and Karekaleng (976 km²) in the Talaud group, in Indonesia. It was described in 1909 from three specimens and no further specimens had been recorded until Riley (2002) found the bat alive on the Talaud Islands. The type locality for this species is Lirong, Talaud Islands, Indonesia.

Population [top]
Population: The population sizes are continuing to be declining due to hunting.
Current Population Trend: Decreasing
Additional data:
? Continuing decline of mature individuals: Yes
? Population severely fragmented: Yes
Habitat and Ecology [top]
Habitat and Ecology: This seems to be a forest-dependent species, but little information is available. This species is thought to be conspicuous due to its roosting habit. It is surprising that they have not been more commonly recorded. Forest habitat on Karakelang is in forest blocks protected under a newly established protected area and the edges of the island are used for agriculture, while on Salebabu there is predominantly agriculture with remnant forest in the low hills (Riley 2001).
Systems: Terrestrial
Continuing decline in area, extent and/or quality of habitat: Yes
Threats [top]
Major Threat(s): Major threats for this species include hunting and habitat loss due to logging (Riley 2001).
Conservation Actions [top]
Conservation Actions: Current conservation efforts
There is a protected area in the species’ range (Karekalang Selatan Hunting Park), but the level of protection for the species remains unknown within this park.
It is listed on CITES Appendix II.
Conservation needs/priorities
Studies are needed on the species’ population sizes, distribution, and extent of occurrence throughout its range. Monitoring of population sizes and locations over time are also important to establish whether these are stable or experiencing trends of decline.
The threats to these bats are poorly understood. Studies are needed on the species’ habitat requirements and on the effects of forest loss and degradation on the species’ population sizes/distribution. Research is also needed on the amount of hunting and the level of bushmeat trade, and the effects of that hunting on population sizes and persistence.
Effective roost site protection efforts are needed to minimize hunting mortality and disturbance to non-target individuals. Similar to most threatened flying foxes, local capacity building for conservation managers and education and awareness within local communities are greatly needed to support conservation efforts.
