Scientific Name: Pteropus cognatus

Assessment Information [top]

Red List Category & Criteria: Endangered B1ab(iii,v) ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): James, R., Hamilton, S. & Helgen, K.
Reviewer(s): Lamoreux, J. (Global Mammal Assessment Team), Racey, P.A., MedellĂ­n, R. & Hutson, A.M. (Chiroptera Red List Authority)
Listed as Endangered because its extent of occurrence is less than 5,000 km2, its distribution is severely fragmented, and there is continuing decline in: the extent and quality of its habitat, and number of mature individuals, due to logging and land conversion for agriculture and hunting.

Geographic Range [top]

Range Description:This poorly-known species is endemic to the Solomon Islands. It has been recorded from the islands of Makira (San Cristobal) and Uki Ni Masi (Flannery 1995). The species was recorded in the early 1990s from Olu Malau (Three Sisters) Island, but these are likely to be vagrants. The total area of the two islands is just over 3,200 km2. It has been found at sea level and at 350 m asl.

Population [top]

Population:Only a few specimens of this species have been collected, and none since the early 1990s. It can be observed around food resources; animals are known to have been harvested recently by local people (R. James pers. comm.). A photograph was taken this species in the late 1990s providing further evidence for its continued presence.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:Yes

Habitat and Ecology [top]

Habitat and Ecology:There is little information on the natural history of this species. It is believed to be solitary (Flannery 1995). A nursing mother was found by day hanging in a banana tree by a river. This species is often seen congregating in small numbers (approximately 3-6 individuals) on fruiting trees close to villages; in these conditions, the species is more vulnerable to hunting (R. James pers. comm.).

Use and Trade [top]

Use and Trade: The species is harvested for food and for its teeth (to make necklaces). The proportion of each use is unknown.

Threats [top]

Major Threat(s): This species is hunted opportunistically for food, and this may be a threat. The species is also hunted for its teeth, which are used in necklaces. Subsistence agriculture and land conversion for cocoa and teak plantations and rice farms could significantly impact this species, due to its highly restricted distribution. Large-scale logging on the western third of Makira is potentially a major threat.

Conservation Actions [top]

Conservation Actions: This species is listed on Appendix II of CITES. It is not known if the species is present in any protected areas. There was a community based conservation program to control hunting in the central Bauro area, but this is no longer active. Further research is needed into population size, ecology, harvest levels, and threats to this species.
