Scientific Name:	Cardioglossa alsco
Species Authority:	Herrmann, Herrmann, Schmitz and Böhme, 2004
Taxonomic Notes:	Records of Cardioglossa pulchra from Tchabal Mbabo (Amiet 1972) now refer to this species (Herrmann et al. 2004).

Assessment Information [top]

Red List Category & Criteria:	Critically Endangered B2ab(iii) ver 3.1
Year Published:	2006
Assessor/s:	Hans-Werner Herrmann
Reviewer/s:	Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson and Neil Cox)
Contributor/s:
Justification: Listed as Critically Endangered because its Area of Occupancy is probably less than 10km2, all individuals are in a single sub-population, and the extent of its forest habitat is declining.

Geographic Range [top]

Range Description:	This recently described species is known only from the southern slopes of Mount Tchabal Mbabo at 1,700-2,100m asl on the Adamawa Plateau in western Cameroon. It is unlikely to occur on the northern slopes, at least not at the altitude of the type locality, because the forest habitat on the northern slopes at this altitude is very different from the gallery forest on the southern slopes.
Countries:	Native: Cameroon

Population [top]

Population:	There is little information, although it is likely to be common within its small range, since 73 specimens were collected close together, suggesting a high concentration of animals.
Population Trend:	Decreasing

Habitat and Ecology [top]

Habitat and Ecology:	It lives in montane gallery forest, and is associated with streams, in which it presumably breeds by larval development. Individuals have been found under large stones around shallow pools adjacent to a creek. They were calling at night during the dry season.
Systems:	Terrestrial; Freshwater

Threats [top]

Major Threat(s):	The remaining forest habitat on Tchabal Mbabo is now confined to galleries and steep inaccessible slopes, as a result of the clearing of forest for pasture. However, much of the forested habitat that can be easily removed has now been cleared. The forest is also threatened by fire.
