Scientific Name:

Xenopus amieti

Species Authority:

Kobel, du Pasquier, Fischberg and Gloor, 1980

Common Name/s:

English

–

Volcano Clawed Frog

Taxonomic Notes:

This species is a tetraploid species (Kobel et al. 1980).

Assessment Information [top]

Red List Category & Criteria:	Near Threatened ver 3.1
Year Published:	2004
Assessor/s:	Richard Tinsley, John Measey
Reviewer/s:	Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson and Neil Cox)
Justification: Listed as Near Threatened since although its Extent of Occurrence is probably less than 20,000 km2 and its habitat might be declining, thus making the species close to qualifying for Vulnerable, it probably occurs in more than ten locations.

Geographic Range [top]

Range Description:	This species is known only from highland areas of western Cameroon, in particular from Mount Manenguba and the Bamileke and Bamenda Plateaus. Specific localities include Mount Manenguba (1,900m asl), the Mifi-Noun River near Galim (1,100m asl), Mbouda (1,400m asl), Tadu (near Mount Oku), Ber, Nkoutoupi, Nchoupa, and Bangourain. It is probable that specimens from Manengole (600-700m asl) and Bangwa (1,400-1,500m asl) belong to this species.

Population [top]

Population:	It is a poorly known species, but it has been found to be abundant at least on Mount Manenguba and at Galim. It is probably generally abundant in the Cameroonian highlands.
Population Trend:	Decreasing

Habitat and Ecology [top]

Habitat and Ecology:	It is water-dependent and has been found in a shallow crater lake overgrown with grass, in a swamp, and in artificial fishponds, generally in areas of montane grassland and pastureland. It breeds in still water, and migrates for short distances over land outside the breeding season.
Systems:	Terrestrial; Freshwater

Threats [top]

Major Threat(s):	It is harvested locally, and some of its habitats might be under threat from expanding agriculture, overgrazing by livestock, and human settlements. However, it does appear to be capable of colonising artificial habitats, and it can co-exist with at least some introduced fish species.
