Assessment Information [top]

Red List Category & Criteria: Critically Endangered B1ab(iii)+2ab(iii) ver 3.1
Year Published: 2014
Date Assessed: 2012-06-03
Assessor(s): IUCN SSC Amphibian Specialist Group
Reviewer(s): Stuart, S.N.
Contributor(s): Msuya, C.A., Menegon, M., Howell, K., Poynton, J. & Loader, S.
Facilitator/Compiler(s): Measey, J.
Listed as Critically Endangered because of its limited extent of occurrence (EOO) and area of occupancy (AOO), both estimated to be 3.3 km2,  in a single threat-defined location, and because of continuing decline of its forest habitat in the Rubeho Mountains.
Previously published Red List assessments:

Geographic Range [top]

Range Description:This species is known only from the Mafwemiro (=Mafwomero) Catchment Forest Reserve in the Rubeho Mountains in eastern Tanzania, between 1,800 and 2,000 m asl. Other nearby forests have been surveyed, but without finding this species, suggesting that its range is truly restricted. Mafwemiro Catchment Forest Reserve is 3.3 km2 which is estimated to be both its maximum extent of occurrence (EOO) and area of occupancy (AOO).
Countries occurrence:
Tanzania, United Republic of
Additional data:
Estimated area of occupancy (AOO) - km2:3.3
Number of Locations:1
Lower elevation limit (metres):1800
Upper elevation limit (metres):2000

Population [top]

Population:It is a relatively recently collected and described species (Poynton 2003). It is not uncommon within the forest, but is apparently less abundant than other Arthroleptis species found in the Eastern Arc Mountains (such as A. affinis, S. Loader pers. comm. July 2013).
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Individuals have been found in leaf litter in this previously degraded montane forest. However, the forest is not fragmented. Like other members of the genus, it presumably breeds by direct development, and is not dependent upon water.
Continuing decline in area, extent and/or quality of habitat:Yes

Use and Trade [top]

Use and Trade: There are no reports of this species being utilized.

Threats [top]

Major Threat(s): Although this species occurs within Mafwemiro Catchment Forest Reserve, this area is not well protected (C. Msuya pers. comm. November 2012), and it is adversely affected by forest loss due to pitsawing (Doggart et al. 2006).

Conservation Actions [top]

Conservation Actions: It occurs in the Mafwemiro Catchment Forest Reserve, which requires additional management efforts. Further survey work would be useful in determining the species' current population status and ecology.
