Scientific Name | Canthium vanwykii Tilney & Kok |
Higher Classification | Dicotyledons |
Family | RUBIACEAE |
Common Names | Pondo Turkey-berry (e) |
National Status |
Status and Criteria | Near Threatened B1ab(iii,v)+2ab(iii,v) |
Assessment Date | 2007/11/27 |
Assessor(s) | L. von Staden & A.T.D. Abbott |
Justification | EOO 2000 km², AOO<2000 km², a range-restricted Pondoland endemic occurring in a highly threatened and restricted habitat, but suspected to occur at more than 10 locations. It continues to decline due to habitat loss and degradation as a result of too frequent and intense grassland fires impacting on forest margins. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Eastern Cape, KwaZulu-Natal |
Range | Oribi Gorge to Lusikisiki. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Eastern Valley Bushveld, Scarp Forest, Pondoland-Ugu Sandstone Coastal Sourveld, KwaZulu-Natal Coastal Belt Grassland |
Description | Forest margins or more rarely in fire protected rocky crevices in grassland on Msikaba Formation Sandstone. |
Threats |
The main threat to Pondoland woody endemics restricted to forest margins is too frequent and intense grassland fires that are causing forest margins to recede (D. Styles, C.R. Scott-Shaw pers. obs.) This threat is affecting forest margins mainly in the areas between Umtamvuna and Mkambati Nature Reserves, and around Lusikisiki.
From Port Edward to Oribi the largest remaining areas of forest are fairly well protected within the Umtamvuna and Oribi Gorge Nature Reserves, however, some areas of forest above the edges of these deep gorges have undoubtedly been cleared for forestry and agriculture (mainly sugarcane) in the past.
Smaller forest patches outside of reserves are threatened by the effects of fragmentation and isolation within a transformed landscape as well as alien invasive encroachment. |
