Scientific Name | Metalasia calcicola P.O.Karis |
Higher Classification | Dicotyledons |
Family | ASTERACEAE |
National Status |
Status and Criteria | Near Threatened B1ab(iii)+2ab(iii) |
Assessment Date | 2009/04/06 |
Assessor(s) | L. von Staden & D. Raimondo |
Justification | EOO 4312-5776 km², AOO < 600 km², 15-20 locations. Habitat and number of locations continue to decline due to coastal development and alien invasive plants. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Coastal areas between Gansbaai and Stilbaai. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Fynbos |
Description | Limestone fynbos, on hills and calcareous dunes below 100 m. |
Threats |
| Coastal development is likely to be causing a continuing decline in habitat and number of locations. One known site near Gansbaai has been recorded during an EIA survey (R. Koopman pers. comm.) Alien invasive plants are threatening subpopulations on the Agulhas Plain as well in the Potberg area of De Hoop Nature Reserve. Near Stilbaai vegetation disturbance to enhance the growth of thatch (Thamnochortus spp.) is a potential threat where sandy soils overlay limestone. |
