Scientific Name: Ruwenzorisorex suncoides (Osgood, 1936)
Common Name(s):
English Ruwenzori Shrew

Assessment Information [top]

Red List Category & Criteria: Vulnerable B2ab(iii) ver 3.1
Year Published: 2016
Date Assessed: 2016-02-10
Assessor(s): Kerbis Peterhans, J.
Reviewer(s): Amori, G.
Contributor(s): Hutterer, R.
Facilitator/Compiler(s): Kennerley, R.
Listed as Vulnerable because its area of occupancy is almost certainly less than 2,000 km², because it is only found near montane streams within a specific forest type, its distribution is presumably severely fragmented, and there is continuing decline in the extent and quality of its forest habitat.

Population [top]

Population:Very few specimens of this species have ever been collected, and little is known about the species overall abundance.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:Yes

Habitat and Ecology [top]

Habitat and Ecology:This species is associated with damp and dense mossy vegetation in montane primary tropical moist forest. It appears to be a specialised semi-aquatic species that has been captured from shallow streams.
Systems:Terrestrial; Freshwater
Continuing decline in area, extent and/or quality of habitat:Yes

Threats [top]

Major Threat(s): This species has a relatively restricted range, within which it is presumably threatened to some degree by habitat loss resulting from logging operations and the general conversion of land to agricultural use.

Conservation Actions [top]

Conservation Actions: This species has been recorded from the Rwenzori Mountains National Park and Bwindi-Impenetrable National Park in Uganda, and Bururi Forest Reserve and Kibira National Park in Burundi. Additional studies are needed into the distribution, abundance, general ecology and threats to this little-known species.

Errata [top]

Errata reason: This errata assessment has been created because the map was accidentally left out of the version published previously.
