Population [top]

Population:In Mangea was only known from one plant, but at some sites in Tanzania, it is abundant.
Current Population Trend:Decreasing
Additional data:
Continuing decline of mature individuals:Yes
Population severely fragmented:Yes

Habitat and Ecology [top]

Habitat and Ecology:A straggling small tree or shrub found in dry evergreen lowland forest and also dry bushland.
Continuing decline in area, extent and/or quality of habitat:Yes

Threats [top]

Major Threat(s): At Mangea most if not all of the forest has gone as a result of agricultural expansion, at Ifakara there is also intensive agriculture so that locality has probably also gone. Pugu Forest Reserve has also been badly impacted by human activities. Other forest reserves where it occurs are better protected.

Conservation Actions [top]

Conservation Actions: Recorded from Saadani National Park (Zaraninge Forest), Banda and Kichi Hills Forest Reserves.
