Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2015
Date Assessed: 2015-07-15

This species was first assessed as Vulnerable under criteria A1c, B1, 2c (World Conservation Monitoring Unit 1998) on the basis that it was threatened by heavy logging and clearance for agriculture. In Cheek et al. (2004) it was stated that "only eight collections are held at Kew from Cameroon and the species occurs only in threatened lowland forest, thus the assessment seems justified and is maintained here". There are now at least 60 specimen records for this taxon and field data suggests that it is a forest pioneer and benefits from disturbance in forest. However forest habitat within its range (particularly in Cameroon) is under great threat, or has already been lost, in over 30% of its range and it is likely that there has been at least a 20% population reduction over the past thirty years (three generations) and that this is ongoing. The species has a very large extent of occurrence, but within this it has a minimum area of occupancy of 168 km² and this is unlikely to exceed the threshold of 2,000 km². While there is continuing decline in extent and quality of habitat, the species is known from at least 30 locations. Based on the above, the species is now assessed as Near Threatened as it almost qualifies for a threatened listing under criteria A2c and B2ab(iii).

Population [top]

Population:The increasing number of collections of this species have extended the known range of this species within Cameroon and outside, hence it appears to be commoner than previously thought. While the population is probably declining overall, it appears to be a pioneer species which needs some degree of disturbance.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:A small tree or shrub found in lowland evergreen forest; 5 to 1,000 m asl.
Continuing decline in area, extent and/or quality of habitat:Yes
Generation Length (years):10

Threats [top]

Major Threat(s): This species is threatened in parts of its range by logging and clearance of forest habitat for agricultural lands, but it is a pioneer species and benefits from disturbance.

Conservation Actions [top]

Conservation Actions: In Cheek et al. (2004) it was stated that "the best hope for the survival of this species is in well-protected lowland evergreen forest reserves, such as Korup. Future plans to better protect the Mungo River Forest Reserve should also help secure the survival of this tree". However, as a pioneer, this species while needing forest, also requires disturbance, so would become rarer if forest was completely protected! This species probably occurs in other protected areas across its wide range.
