Scientific Name | Adenandra villosa (P.J.Bergius) Licht. ex Roem. & Schult. subsp. robusta Strid |
Higher Classification | Dicotyledons |
Family | RUTACEAE |
National Status |
Status and Criteria | Near Threatened B1ab(iii)+2ab(iii) |
Assessment Date | 2019/03/25 |
Assessor(s) | L. von Staden |
Justification | A range-restricted (EOO 314 km²), but locally common taxon. It is declining due to coastal development, but still remains at more than 10 locations. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Rooiels to Kleinmond. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Kogelberg Sandstone Fynbos, Hangklip Sand Fynbos |
Description | Lower sandstone slopes. |
Threats |
At Rooi Els, Pringle Bay, Betty's Bay and Kleinmond, this taxon is threatened by ongoing habitat loss to coastal development. It has lost habitat to timber plantations in the Highlands area above Kleinmond in the past, and continues to be threatened by spreading alien invasive plants in some areas close to plantations. |
Population |
This taxon has a restricted range, but is known from a large number of records. Many collections indicate it to be locally common. Subpopulations along the coast are declining, but those in the Kogelberg Mountains further inland are not threatened.
