English Johnston's Forest Shrew, Johnston's Shrew

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Hutterer, R. & Kerbis Peterhans, J.
Reviewer(s): Amori, G. (Small Nonvolant Mammal Red List Authority) & Cox, N. (Global Mammal Assessment Team)
Justification:
Listed as Least Concern in view of its wide distribution, presumed large population, it occurs in a number of protected areas, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
History:
2004 Least Concern
1996 Lower Risk/least concern (Baillie and Groombridge 1996)

Geographic Range [top]

Range Description: This species has a seemingly disjunct distribution, being found in much of western Central African, and then in parts of eastern Central Africa and East Africa. In the west of its range it is found in Cameroon, Equatorial Guinea (Bioko and Rio Muni), Gabon, Congo and southwestern Central African Republic. In the east of its range it is present in eastern Democratic Republic of the Congo, Rwanda, Burundi, Uganda (including Sango Bay Forest), northwestern Tanzania, and is possibly present in southwestern Kenya (Hutterer 1986; Dowsett and Granjon 1991; Quérouil et al. 2003; Hutterer 2005). It is unclear if the species ranges across the Congo basin between the two known populations. In the west of its range it has been recorded from 100 to 625 m asl; in the east it is found from 1,000 to 2,250 m asl.
