Scientific Name | Oxalis aridicola T.M.Salter |
Higher Classification | Dicotyledons |
Family | OXALIDACEAE |
National Status |
Status and Criteria | Vulnerable D2 |
Assessment Date | 2012/05/10 |
Assessor(s) | K.C. Oberlander & L. von Staden |
Justification | A very localized (EOO <75 km², AOO <20 km²), but locally very abundant species that is potentially threatened by habitat loss to crop cultivation. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Eastern Cederberg, flats between Pakhuis and Doornbosch. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Agter-Sederberg Shrubland, Doringrivier Quartzite Karoo |
Description | Sandy and clay flats. |
Threats |
| A small proportion of this species' habitat has been converted to crop fields, and cultivation is expanding sporadically. It is however not known whether ploughing is causing a decline or favouring this species - some species of Oxalis are known to multiply in response to disturbance, and/or are able to quickly recolonize disturbed sites. Oxalis aridicola has been observed growing in large numbers even in badly eroded sites. |
Population |
A localized, but locally extremely abundant species with hundreds of thousands of plants dominating the veld in winter. The number of flowering plants vary according to annual rainfall.
|
Population trend | Stable |
