Justification | A highly localized habitat specialist (EOO <5 km², AOO <1 km²), known from a single subpopulation that is potentially threatened by competition from alien invasive plants and too frequent fire. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Houw Hoek Mountain above Houw Hoek Station. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Western Coastal Shale Band Vegetation |
Description | Marshy ground on shale bands, 450-600 m. |
Threats |
| This species is potentially threatened by too frequent fire, as well as competition from alien invasive pines, which are present in nearby mountain fynbos and is likely to spread if left unmanaged (Linder 2011). |
Population |
This species is a localized habitat specialist and is known from one subpopulation. The population is currently stable, but may decline if competition from alien invasive plants increase.
