Conservation Actions [top]

Conservation Actions: Conservation Actions
It occurs in the Udzungwa Scarp Forest Reserve and is the subject of a monitoring program (M. Menegon pers. comm. October 2015). Protection of critical habitat is expected to improve as the Forest Reserve will become a Nature Reserve, which should reduce encroachment (S. Loader pers. comm. October 2015).

Conservation Needed
Ongoing and improved protection of the species habitat is required.

Research Needed
Further research is required to clairfy the species' distribution, population status and additional threats information.
