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, Kim Howell
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 and swamp habitat in the Udzungwa Mountains is declining.

Geographic Range [top]

Range Description: This species is known only from the Luhega Forest in the Udzungwa Scap Forest Reserve at 1,740m asl in the Udzungwa Mountains in eastern Tanzania. It is probably more widespread in the Udzungwa Mountains, though it appears to be absent from apparently suitable sites close to the type locality.
Countries occurrence:
Tanzania, United Republic of

Population [top]

Population: It is common in its only known locality.
Current Population Trend: Decreasing
Additional data:
Population severely fragmented: No

Habitat and Ecology [top]

Habitat and Ecology: It has been found in swamps in dense montane forest. Its breeding biology is unknown, though it is likely to take place in swamps. Its adaptability to altered habitats is unknown.
Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): The main threat to the species is likely to be the loss of habitats for agriculture, livestock, wood extraction, and human settlements.

Conservation Actions [top]

Conservation Actions: It occurs in the Udzungwa Scap Forest Reserve; it could also occur in the Udzungwa National Park, although its presence there has not yet been confirmed.
