Assessment Information [top]

Red List Category & Criteria: Endangered B1ab(iii) ver 3.1
Year Published: 2013
Date Assessed: 2012-06-03
Assessor(s): IUCN SSC Amphibian Specialist Group
Reviewer(s): Stuart, S.
Contributor(s): Poynton, J., Howell, K., Menegon, M. & Loader, S.
Facilitator/Compiler(s): Angulo, A.
Justification:
Listed as Endangered because its extent of occurrence (EOO) is estimated to be approximately 444 km2, it is estimated to occur in two threat-defined locations, and there is a continuing decline of its habitat in the Eastern Arc of Tanzania.
Previously published Red List assessments:

Geographic Range [top]

Range Description:This species is known only from the upper elevations (1,800-2,500 m asl) of the Uluguru Mountains in eastern Tanzania. It is unlikely to occur more widely (S. Loader pers. comm. June 2012). Taking range as a proxy for extent of occurrence (EOO), this is estimated to be 444 km2. It is estimated to occur from two threat-defined locations, Uluguru North and Uluguru South (S. Loader pers. comm. June 2012).

Tanzania, United Republic of

Population [top]

Population:It is a locally relatively common species (S. Loader pers. comm. June 2012). Its population is not considered to be severely fragmented.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:It is a species of montane grassland which also occurs marginally in montane forest, where it lives on the ground and is semi-fossorial. It tolerates marginally disturbed habitats (S. Loader and K. Howell pers. comm. June 2012). The eggs are deposited under grass tufts in burrows where they breed by direct development without a larval stage (S. Loader pers. comm. June 2012).
Systems:Terrestrial
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): It is very likely to be adversely affected by ongoing forest loss, especially due to subsistence small-scale agriculture, and pole cutting and logging (S. Loader pers. comm. June 2012). Montane grasslands are susceptible to human-induced fires and this species could therefore be affected (K. Howell pers. comm. June 2012).

Conservation Actions [top]

Conservation Actions: It occurs in the Uluguru Nature Reserve. Although this reserve is relatively well protected in comparison to other protected areas in the region, there is still a need for increased protection and improved management (S. Loader pers. comm. June 2012). More information is needed on this species' distribution, population status and natural history.
