Scientific Name | Erica alfredii Guthrie & Bolus |
Higher Classification | Dicotyledons |
Family | ERICACEAE |
National Status |
Status and Criteria | Vulnerable D1+2 |
Assessment Date | 2012/08/09 |
Assessor(s) | E.G.H. Oliver, R.C. Turner & L. von Staden |
Justification | A single, localized subpopulation of fewer than 1000 mature individuals is confined to an EOO of less than 1 km² and potentially threatened by competition from alien invasive plants. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Riviersonderend Mountains, Pilaarkop. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | South Sonderend Sandstone Fynbos |
Description | High altitude, rocky, north-facing slopes. |
Threats |
| Invasive alien pines are present in high densities on the lower slopes of the Riviersonderend Mountains, and are spreading upwards. Although not yet present within the habitat of Erica alfredii, if left unmanaged, it is likely to encroach onto this species' habitat in future. |
Population |
Erica alfredii is known from a single, localized subpopulation consisting of between 500 and 1000 mature individuals. It is confined to a specialized, high altitude rocky summit habitat, but has not yet been recorded from similar habitat on other well-explored nearby peaks in the Riviersonderend Mountains. The population is not suspected to be declining.
