Scientific Name | Cullumia squarrosa (L.) R.Br. |
Higher Classification | Dicotyledons |
Family | ASTERACEAE |
Synonyms | Berkheya squarrosa (L.) Willd., Gorteria squarrosa L. |
Common Names | Grootsteekhaarbos (a) |
National Status |
Status and Criteria | Vulnerable B1ab(ii,iii,iv,v) |
Assessment Date | 2012/07/06 |
Assessor(s) | D. Raimondo, N.A. Helme & L. von Staden |
Justification | EOO 4586-5757 km², between five and 10 remaining locations continue to decline due to ongoing habitat loss and degradation due to expansion of urban and coastal development, competition from unmanaged alien invasive plants and overgrazing. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Cape Peninsula to the Agulhas Plain. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Overberg Dune Strandveld, Cape Flats Dune Strandveld, Peninsula Sandstone Fynbos, De Hoop Limestone Fynbos, Agulhas Limestone Fynbos, Peninsula Granite Fynbos, Albertinia Sand Fynbos, Hangklip Sand Fynbos, Cape Flats Sand Fynbos |
Description | Deep sandy coastal flats. |
Threats |
| Threatened by habitat loss to urban expansion on the Cape Peninsula, and coastal development further east. Competition from unmanaged alien invasive plants threaten remaining plants around Macassar and on the Agulhas Plain, where one known subpopulation is also threatened by overgrazing. |
Population |
Historical records indicate that this species was formerly very common on sandy coastal lowlands from the Cape Peninsula to the Agulhas Plain, but much of these areas have now been transformed for urban and coastal development, with many subpopulations now lost around Noordhoek, Simon's Town, Macassar, Pringle Bay and Hermanus. It is however still common in the Cape Point section of the Table Mountain National Park, but has also been overlooked and undersampled elsewhere and is possibly more common than records indicate (N.A. Helme pers. comm. 2012).
