Taxonomy [top]

Kingdom Phylum Class Order Family
PLANTAE TRACHEOPHYTA MAGNOLIOPSIDA VIOLALES BEGONIACEAE

Scientific Name: Begonia preussii
Species Authority: Warb.

Assessment Information [top]

Red List Category & Criteria: Vulnerable A3c ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Assessor/s: Cheek, M.
Reviewer/s: Hilton-Taylor, C. & Pollock, C.M. (Red List Programme Office)
Justification:
This taxon was previously assessed as Endangered (Cable and Cheek 1998) but is here downgraded to Vulnerable in the light of the taxonomic revision by de Wilde (2002) showing it to be more common and widespread in Cameroon than was previously thought. In addition, the discovery of eight further specimens at five sites in Mt Kupe-Bakossi Mts confirms the foregoing. Nonetheless, due to the low altitudinal range of this taxon, habitat loss of about 30% over the next 15 years (estimated as equating to three generations) can be postulated.
History:
2000 Endangered

Habitat and Ecology [top]

Habitat and Ecology: Found in evergreen forest, 850–1,000 m alt.
Systems: Terrestrial

Threats [top]

Major Threat(s): clearance of forest for wood and agricultural land (especially plantations) is a major threat throughout its range and probably accounts for the lack of collections from Bioko in the last century (where forest was largely cleared below 1,000 m alt.).

Conservation Actions [top]

Conservation Actions: This taxon is most likely to survive in lowland forest reserves such as the Bakossi F.R. and Mokoko F.R., but only if their boundaries are respected. Resources need to be found to achieve this.
