Year Published: 2016
Date Assessed: 2015-10-02
Assessor(s): IUCN SSC Amphibian Specialist Group
Reviewer(s): Stuart, S.N.

Justification:
Listed as Endangered because its extent of occurrence (EOO) is 426 km2, it is only known from two locations, and there is continuing decline in the quality and the extent of its habitat.
Previously published Red List assessments:

Geographic Range [top]

Range Description:This species is known from the Shimba Hills National Reserve south to Buda Forest in coastal Kenya where it is found between 30-400 m asl. South of Mombasa it is replaced by Hyperolius mitchelli implying its range is restricted to these areas. There are two threat defined locations (in and outside of the Shimba Hills National Reserve). Using the range as a proxy, the extent of occurrence (EOO) is estimated to be 426 km2.

Population [top]

Population:It is abundant in suitable habitat and, while its population size is unknown, it is suspected to be decreasing due to ongoing habitat loss. Wetland modification outside the National Reserve may negatively affect the population.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:Unknown

Habitat and Ecology [top]

Habitat and Ecology:It occurs in a mosaic of moist coastal forest and densely vegetated wetlands (including moderately degraded former forest) where it breeds by larval development.
Systems:Terrestrial; Freshwater
Continuing decline in area, extent and/or quality of habitat:Yes
Movement patterns:Not a Migrant

Use and Trade [top]

Use and Trade: There are no reports of this species being utilized.

Threats [top]

Major Threat(s): Outisde the National Reserve the species is threatened by deforestation caused by expanding agriculture and human settlements. Chytrid fungus has been recorded in the Shimba Hills, but it is not known if this species is affected (Kielgast et al. 2010).

Conservation Actions [top]

Conservation Actions: Conservation Actions
It occurs in the Shimba Hills National Reserve, which is a popular tourist destination and is therefore relatively well managed. It also occurs in the Gongoni and Buda Forest Reserves which are in need of improved management.

Conservation Needed
Ongoing and improved habitat protection and management is required.

Research Needed
Further research is required on the species distribution, population status, and taxonomy. Additional studies should identify amphibian species at risk of chytridiomycosis infection in the Shimba Hills.
