Scientific Name | Erica extrusa Compton |
Higher Classification | Dicotyledons |
Family | ERICACEAE |
National Status |
Status and Criteria | Critically Endangered B1ab(iii,v)+2ab(iii,v) |
Assessment Date | 2012/08/24 |
Assessor(s) | E.G.H. Oliver, R.C. Turner & L. von Staden |
Justification | An extremely localized species, EOO <1 km², and known from one location where the only known remaining subpopulation is threatened by competition from alien invasive plants, orchard expansion and dam construction. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Palmiet River Valley near Elgin. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Kogelberg Sandstone Fynbos |
Description | Sandy flats and stony, rocky areas with quartzitic gravels. |
Threats |
| Extensive habitat transformation within the Elgin Valley has likely led to the loss of the majority of this species' habitat, and it is currently known from a single remaining subpopulation. It is threatened by competition from alien invasive plants and potentially expansion of nearby fruit orchards and enlargement of the Arieskraal Dam. |
Population |
This species is known from a single, localized subpopulation.
