Assessment Information
|
Red List Category & Criteria:
|
EN B1ab(iii) ver 3.1 (2001)
|
|
Year Assessed:
|
2004
|
|
Assessor/s:
|
Schiøtz, A. & Drewes, R.
|
|
Evaluator/s:
|
Stuart, S., Chanson, J. & Cox, N. (Global Amphibian Assessment Coordinating Team)
|
|
Justification:
|
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
|
Range Description:
|
This species is known only from the Shimba Hills, south of Mombassa, in coastal Kenya, being replaced further south by Hyperolius mitchelli.

Habitat and Ecology
|
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.
|
|
System:
|
Terrestrial; Freshwater
|
|
List of Habitats:
|
| 1.5 | Forest - Subtropical/Tropical Dry |
| 2.2 | Savanna - Moist |
| 5.4 | Wetlands (inland) - Bogs, Marshes, Swamps, Fens, Peatlands |
| 5.8 | Wetlands (inland) - Seasonal/Intermittent Freshwater Marshes/Pools (under 8ha) |
| 14.4 | Artificial/Terrestrial - Rural Gardens |
| 14.6 | Artificial/Terrestrial - Subtropical/Tropical Heavily Degraded Former Forest |
|
Threats
|
Threats:
|
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.
|
|
List of Threats:
|
| 1.1.1.2 | Habitat Loss/Degradation - Agriculture - Crops - Small-holder farming (ongoing) |
| 1.3.3.1 | Habitat Loss/Degradation - Extraction - Wood - Small-scale subsistence (ongoing) |
| 1.4.2 | Habitat Loss/Degradation - Infrastructure development - Human settlement (ongoing) |
| 9.9 | Intrinsic factors - Restricted range (ongoing) |
|
Conservation Actions
|
Conservation Actions:
|
It probably occurs in the Shimba Hills National Reserve, which is in need of strengthened management.
