Justification | This species has an extent of occurrence (EOO) of 48 071 km², and an area of occupancy (AOO) of 420 km². It is known from more than 30 subpopulations, which are not severely fragmented. It has lost significant amounts of habitat to urban and coastal development as well as agriculture, but it is able to tolerate severe disturbance. However, coastal development is causing ongoing, irreversible habitat loss and although this species is not threatened at the moment, it should be monitored. It is listed as Least Concern. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | It is endemic to South Africa, and is found in the Western Cape. It is common in the coastal areas from Lambert's Bay in the north to Stilbaai in the southeast, and it is also found inland around Darling and Piketberg. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Fynbos |
Description | It occurs on sandy, mainly coastal, flats and dunes in strandveld and fynbos, rarely a short distance inland. |
Threats |
| This species is described in Goldblatt and Manning (2007) as one of the most common species of the genus Babiana, which is confirmed by the c 100 collections of this species in the SANBI Pretoria and Cape Town herbaria (PRE, SAM and NBG). However, more than 80% of these collections were made prior to 1970. It has lost 45% of its habitat (calculated using landcover data in GIS), and many of the previous collections are from areas now completely transformed by urban development, such as the Cape Flats, and although this species appears to be tolerant of disturbance - it has been recorded from old fields, growing under alien Acacias and from other heavily disturbed areas such as landfill sites. However, urban and coastal development is causing ongoing irreversible habitat loss over much of the range of this species, and is likely to cause more local extinctions such as on the Cape Flats. |
Population |
It has at least 12 subpopulations, and the population is not under threat.

Population trend | Decreasing |
Conservation |
| It is conserved at De Hoop Nature Reserve. |
