Assessment Date | 2016/01/15 |
Assessor(s) | L. von Staden |
Justification | A localized habitat specialist (EOO 404 km²), known from three locations and potentially threatened by competition from alien invasive plants and coastal development. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Bredasdorp. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Overberg Dune Strandveld, De Hoop Limestone Fynbos, Agulhas Limestone Fynbos |
Description | Crevices in limestone outcrops in coastal fynbos. |
Threats |
| This species is potentially threatened by competition from alien invasive plants - much of the coastal fynbos on the Agulhas Plain is densely infested with alien invasive plants, and ongoing clearing is needed. Another potential threat is coastal development: none of the known locations are currently threatened by development, but it remains a potential threat in all coastal areas. |
