|Scientific Name:||Crocidura grandiceps|
|Species Authority:||Hutterer, 1983|
|Red List Category & Criteria:||Near Threatened ver 3.1|
|Reviewer/s:||Amori, G. (Small Nonvolant Mammal Red List Authority) & Cox, N. (Global Mammal Assessment Team)|
Listed as Near Threatened, as although the species is relatively widespread, and is not believed to be declining at a rate of at least 30% over a ten year period, the areas of untouched primary forest in West Africa from which this species has been recorded (and is restricted to) are now small and fragmented, with habitat destruction continuing at most of these localities. Almost qualifies as threatened under criterion A2c.
|Range Description:||This West African species has been recorded from Guinea (Decher 2004, Decher et al. 2009, Nicolas et al. 2009), Liberia (Decher et al. 2011), Côte d'Ivoire (with an important population in Taï National Park [Churchfield et al. 2004, Quérouil et al. 2005]), Ghana (type locality of the Krokosua Hills and Atiwiredu [Weber and Fahr 2007]), southern Benin (Bekker and Ekou 2004), Nigeria (west of the Niger River, but may occur to the east [Happold 1987]) and is possibly present in Cameroon (a dubious record from Korup National Park). Grubb et al. (1998) suggest that the species might range as far west as Sierra Leone.|

|Population:||In general, C. grandiceps appears to be relatively uncommon. Taï forest in Côte d'Ivoire probably contains one of the largest populations of this species. Surveys at the type locality in 2003 did not encounter any animals (Jan Decher pers. comm.).|
|Habitat and Ecology:||This species is largely associated with primary lowland tropical moist forest. The type specimen was trapped in a natural grassy clearing in high forest at 1,800 m asl; paratypes were collected on a cocoa farm and in a hole in the ground in secondary bush (Hutterer 1983; Grubb et al. 1998). In Ghana, the habitat of this species is now composed of small, scattered forest fragments.|
|Major Threat(s):||C. grandiceps is threatened by continuing general habitat destruction, fragmentation, and degradation, especially in parts of Nigeria and Ghana.|
|Conservation Actions:||The species has been recorded from Taï National Park, Côte d'Ivoire. There is a need to affectively conserve remaining areas of suitable forest habitat for this species. Additional studies are needed into the species distribution, natural history and threats. There is a need to actively monitor known populations of this species, and to survey remaining forest fragemnts to locate any additional viable populations.|
