Kingdom Phylum Class Order Family
ANIMALIA CHORDATA MAMMALIA RODENTIA MURIDAE

Scientific Name: Uromys boeadii
Species Authority: Groves & Flannery, 1994
Common Name(s):
English Biak Giant Rat

Assessment Information [top]

Red List Category & Criteria: Critically Endangered A4cd ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Leary, T., Seri, L., Flannery, T., Wright, D., Hamilton, S., Helgen, K., Singadan, R., Allison, A., James, R., Bonaccorso, F. & Aplin, K.
Reviewer(s): Lamoreux, J. (Global Mammal Assessment Team) & Amori, G. (Small Nonvolant Mammal Red List Authority)
Justification:
Listed as Critically Endangered because of a drastic population decline, estimated to be more than 80% over a ten year period (5 years in the past and 5 in the future), inferred and projected from the continuing loss habitat on Biak Island and the potential loss of mature individuals due to hunting.

Geographic Range [top]

Range Description: This recently-described species has been recorded from the island of Biak, Indonesia. It was collected close to Biak town in 1963. This area has since been deforested. It is possible that the species may be present also on the island of Supiori, although this requires confirmation.

Population [top]

Population: It has only been collected once (a single specimen) in five expeditions to Biak. The population is believed to be small.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: Nothing has been recorded about the natural history of this species. It presumably occurs in tropical moist forest.
Systems: Terrestrial

Threats [top]

Major Threat(s): Although this species is poorly-known, it is presumed that hunting for food by local people and habitat loss through deforestation for timber and conversion to cultivated land are threats. At least >50% of the forest on Biak has been cleared. There is still available habitat on the island of Supiori.

Conservation Actions [top]

Conservation Actions: It is not known if this species is present in any protected areas. Further field studies are needed to locate any remaining populations and also to study the natural history of this little-known species.
