Geographic Range [top]

Range Description:This species occurs in the East Usambara, Uluguru, Nguru, Nguu, Mahenge and Udzungwa Mountains, in eastern and southern Tanzania. Some localities have been removed from this concept: the West Usambara subpopulation was allocated N. vestergaardi, and the Ukaguru subpopulation to N. paulae and N. laticeps. This species was mistakenly recorded as occuring in the Southern Highlands of Tanzania, but this has not been verified and these records have been removed from this assessments; similarly, reports that it occurs on Mount Rungwe need confirmation. It occurs from 300 m (Kimboza Forest in the Uluguru foothills) up to at least 1,500 m asl. The extent of occurrence (EOO) is 48,562 km2 and area of occurrence (AOO) is 2,879 km2.

Population [top]

Population:It is one of the most abundant amphibian species in the overall Eastern Arc mountain range. However, its population is suspected to be both severely fragmented and decreasing due to ongoing habitat loss and degradation.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:Yes

Habitat and Ecology [top]

Habitat and Ecology:It lives in lowland and montane forest 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 [top]

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

Threats [top]

Major Threat(s): Its habitat is being disturbed, and to a lesser extent lost, especially at lower altitudes, due to agricultural encroachment, wood extraction and expanding human settlements.
