This species is known from Jozani Forest on Unguja Island (Zanzibar), Tanzania, and Arabuko-Sokoke Forest in coastal Kenya. It is likely to be found in other forested localities on the East African coast. Its extent of occurrence (EOO) is 3,361 km2.
Habitat and Ecology
Both known sites are in coastal forest where it lives in forested habitats. It presumably breeds in water by larval development.
This species appears to be abundant in Jozani Forest. However due to ongoing declines in the extent and quality of habitat, the population is suspected to be decreasing.
The main threats are expanding agriculture and removal of timber, and this species is probably unable to adapt to loss of its forest habitat (Pickersgill, 2007).
It occurs in Arabuko-Sokoke National Park. Jozani Forest is within the Proposed Jozani-Chwaka Bay National Park.
Both of these national parks need increased protection.
Surveys are needed to determine whether or not this species is present in other areas.
Red List Status
Listed as Endangered because its extent of occurrence (EOO) is 3,361 km2, all individuals occur in fewer than five threat-defined locations, and there is continuing decline in the extent and quality of its habitat.
