|Contributor(s):||Liedtke , C., Howell, K., Poynton, J. & Loader, S.|
|Facilitator/Compiler(s):||Morris, E.J. & Luedtke, J.|
Listed as Least Concern because of its wide distribution, presumed large population, and degree of tolerance to disturbance.
|Previously published Red List assessments:|
|Range Description:||In the previous assessment, this species was known only from the Uluguru and Udzungwa Mountains in the east and Mount Rungwe in the south of Tanzania. Its range has been expanded to include Mahenge, the Livingston and Rubeho Mountains. It is a montane species ranging from 1,350-2,800m asl occurring in approximately six threat-defined locations. The extent of occurrence (EOO) is 55,263 km2 and a rough estimate of its area of occupancy (AOO) equals 2,399 km2.|

|Population:||It is a relatively common species, but its population is suspected to be both severely fragmented and decreasing due to ongoing habitat loss and degradation.|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||It lives in sub-montane and montane forest, and montane grassland, where it is found low in the vegetation and on the ground. It can tolerate some disturbance to its habitat and can survive in banana plantations, but probably not in very open areas. It breeds by internal fertilization, the females retaining the larvae internally in the oviduct until little toadlets are born.|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Movement patterns:||Not a Migrant|
|Use and Trade:||This species has been reported as being illegally traded (K. Howell pers. comm. June 2012).|
|Major Threat(s):||The major threat to this species is habitat disturbance, especially at lower altitudes, due to agricultural encroachment, wood extraction and expanding human settlements.|
It occurs in several forest reserves, including the Uluguru Nature Reserve. It might occur in the Udzungwa National Park, but has thus far not been recorded. It is listed on CITES Appendix I.
Improved protection of its habitat and management of protected areas is required.
Further information is required on the species' distribution and population status.
