Population [top]

Population: There is little information available on its population status. However, the fact that 23 specimens have been found widely over the West Usambara Mountains, despite limited survey effort, suggests that it is not uncommon in suitable habitat within its small range.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: All records have been from montane and submontane forest, including in the ecotone between forest and ericaceous vegetation. It is probably terrestrial, and some animals were found inside a rotten log. Its breeding is unknown, but it is assumed to be ovoviviparous, like other members of its genus, with internal fertilization, giving birth to tiny toadlets.
Systems: Terrestrial

Threats [top]

Major Threat(s): In some parts of the West Usambaras its habitat is probably being lost, especially due to agricultural encroachment, commercial logging, wood extraction, and expanding human settlements.

Conservation Actions [top]

Conservation Actions: It occurs in the University of Dar es Salaam's forest reserve at Mazumbai, but additional protection of the habitat in the West Usambara Mountains is needed. It is listed on CITES Appendix I.
