Assessment Information [top]

Red List Category & Criteria: Endangered B1ab(i,ii,iii,iv,v) ver 3.1
Year Published: 2009
Date Assessed: 2006-03-02

Reviewer(s): Beentje, H., Gereau, R., Kabuye, C., Kalema, J., Luke, Q., Lyaruu, H., Maunder, M., Mwachala, G., Ndangalasi, H., Njau, F. & Schatz, G. (East African Plants Red List Authority)
Justification:
This species has an extent of occurrence of only about 540 kmĀ², is severely fragmented and there is continuing decline because of forest loss and deterioration. It has probably gone extinct in Kenya and may have been lost from places in Tanzania because of human activities.
History:
1998 Vulnerable (Oldfield et al. 1998)
1998 Vulnerable
1997 Indeterminate (Walter and Gillett 1998)

Population [top]

Population: In Mangea was only known from one plant, but at some sites in Tanzania, it is abundant.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: A straggling small tree or shrub found in dry evergreen lowland forest and also dry bushland.
Systems: Terrestrial

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.
