Assessment Information [top]

Red List Category & Criteria: Endangered B1ab(iii) ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Needs updating
Assessor(s): Arne Schiøtz, Robert Drewes
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson and Neil Cox)
Listed as Endangered because its Extent of Occurrence is probably less than 5,000 km2, it is known from fewer than five locations, and the quality and extent of its forest habitat on the Kenyan coast is declining.

Geographic Range [top]

Range Description:This species is known only from the Shimba Hills, south of Mombassa, in coastal Kenya, being replaced further south by Hyperolius mitchelli.

Population [top]

Population:It is common in its tiny range.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:It lives in dry forest, dense humid savannah, and heavily degraded former forest (farm bush). It breeds in marshes and temporary pools.
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): Although somewhat adaptable, there is a limit to the amount of opening up of its habitat that it can tolerate, and so it is probably impacted by agricultural expansion and increasing human settlements.

Conservation Actions [top]

Conservation Actions: It probably occurs in the Shimba Hills National Reserve, which is in need of strengthened management.
