Habitat and Ecology [top]

Habitat and Ecology: It is a terrestrial species living in forest, bamboo, and grasslands at the forest edge. It has been found in maize cultivation, but needs to be close to the forest edge, and probably cannot tolerate complete opening up of its habitat. It breeds by internal fertilization, the females retaining the larvae internally in the oviduct until little toadlets are born.
Systems: Terrestrial

Threats [top]

Major Threat(s): The major threat to this species is habitat loss, especially at lower altitudes, due to agricultural encroachment, wood extraction and expanding human settlements.

Conservation Actions [top]

Conservation Actions: It occurs in several forest reserves, but has not been found in any well-protected area. It might occur in the Udzungwa National Park, but has thus far not been recorded. It is listed on CITES Appendix I.
