Assessment Date | 2014/09/23 |
Assessor(s) | J.G. Claassens, K.C. Oberlander & D. van der Colff |
Justification | EOO of 71 km², AOO <71 km² and there might be fewer than nine locations. It continues to decline, due to the development of human settlements and mining, as well as habitat degradation due to agricultural expansion. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Vredenburg Peninsula. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Saldanha Limestone Strandveld, Saldanha Granite Strandveld |
Description | Limestone strandveld. |
Threats |
| This species occurs on the West-Coast, a favoured holiday destination. Recently the number of permanent residences have increased, and some areas are used for grazing and mining activities. Hence the main threats to this species are habitat loss due to human settlement and mining and habitat degradation due to agricultural activities (J.G. Claassens, pers. comm.). |
Population |
This species is very similar to Oxalis hirta and hence there might be an over estimation of the actual number of locations and sub-populations.

Population trend | Decreasing |
