Guinea Screeching Frog

Assessment Information [top]

Red List Category & Criteria:	Endangered B1ab(iii) ver 3.1
Year Published:	2004
Assessor/s:	Mark-Oliver Rödel, Robert Drewes
Reviewer/s:	Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson and Neil Cox)
Contributor/s:
Justification: This species is known only from the type locality and is listed as Endangered because its Extent of Occurrence is less than 5,000 km2, it is known from fewer than five locations, and the quality and extent of its forest habitat on Mount Nimba is declining.

Geographic Range [top]

Range Description:	This species is known only from Mount Nimba in Guinea; it presumably also occurs in the Liberian and Ivorian parts of Mount Nimba, but this has not yet been confirmed. It has been recorded from 500-1,650m asl.
Countries:	Native: Guinea

Population Trend:	Decreasing

Habitat and Ecology [top]

Habitat and Ecology:	It lives in high-altitude grassland, gallery forest, and on the edges of marshes. Like other members of the genus, it presumably breeds by direct development and is not dependent upon water.
Systems:	Terrestrial; Freshwater

Threats [top]

Major Threat(s):	The major threat to the species is habitat loss and degradation, since Mount Nimba is subject to slash-and-burn agricultural activities and extensive iron-ore mining operations.

Conservation Actions [top]

Conservation Actions:	The species occurs in the Mont Nimba Strict Nature Reserve, which was added to the list of World Heritage Sites in 1981 (the adjacent part in Cote D'Ivoire was added in 1982). However, strengthened and improved management of this site is needed, and further survey work is required to determine the current population status of the species.
