Assessment Information [top]

Red List Category & Criteria:

Critically Endangered B1ab(iii) ver 3.1

Year Published:

2008

Assessor/s:

Hutterer, R.

Reviewer/s:

Amori, G. (Small Nonvolant Mammal Red List Authority) & Cox, N. (Global Mammal Assessment Team)

Justification:
Listed as Critically Endangered (Possibly Extinct) because its extent of occurrence is probably less than 100 km², all individuals are in a single location, and all suitable habitat might have been cleared within the species seemingly limited range.

History:

2004	–	Critically Endangered
1996	–	Endangered
1994	–	Insufficiently Known (Groombridge 1994)
1990	–	Insufficiently Known (IUCN 1990)

Geographic Range [top]

Range Description:	Crocidura wimmeri appears to be endemic to southern Côte d?Ivoire, where it seems to be restricted to the area surrounding Adiopodoume. Records of this species from outside Côte d?Ivoire are based on misidentifications. Specimens recorded from Cameroon and Gabon refer to Crocidura batesi (Brosset 1988; Hutterer 2005).
Countries:	Possibly extinct: Côte d'Ivoire

Population [top]

Population:	Studies suggest that this is a rare species. It has not been recorded since 1976.
Population Trend:	Unknown

Habitat and Ecology [top]

Habitat and Ecology:	This species is known only from moist savanna habitat.
Systems:	Terrestrial

Threats [top]

Major Threat(s):	It is believed that all suitable habitat for this species in the area of Adiopodoume has now been cleared, presumably largely through the conversion of land to agricultural use.
