Scientific Name:	Callixalus pictus
Species Authority:	Laurent, 1950

Assessment Information [top]

Red List Category & Criteria:	Vulnerable B1ab(iii) ver 3.1
Year Published:	2004
Assessor/s:	Arne Schiøtz
Reviewer/s:	Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson and Neil Cox)
Contributor/s:
Justification: Listed as Vulnerable because its Extent of Occurrence is probably less than 20,000 km2, its distribution is severely fragmented, and the extent of its forest habitat in the Albertine Rift mountains is declining.

Geographic Range [top]

Range Description:	This species is known only from the Itombwe and Kabobo highlands of eastern Democratic Republic of Congo, and from the mountains of western Rwanda. It has never been found below 2,100m, and is rare below 2,400m asl. There have been no recent records of this species, presumably due to lack of fieldwork within its range.
Countries:	Native: Congo, The Democratic Republic of the; Rwanda

Population [top]

Population:	There is no recent information on the population status of this species.
Population Trend:	Decreasing

Habitat and Ecology [top]

Habitat and Ecology:	It is a species of high-altitude forests, especially bamboo forest. By day, it hides in broken bamboo stems at 2-4m above the ground, or, where bamboo is scarce, it hides between bark and moss, which covers the tree trunks. There is no information on its breeding, but it is presumed to breed in water.
Systems:	Terrestrial

Threats [top]

Major Threat(s):	There is no direct information, but it is restricted to unprotected habitats that are probably being lost due to agriculture, wood extraction, and expanding human settlements.

Conservation Actions [top]

Conservation Actions:	It is not known from any protected areas. There is a need for improved habitat protection at sites where this species is known to occur, such as on the Itombwe massif. Further survey work is required to determine the current population status of the species.
