National Status |
Status and Criteria | Endangered B1ab(ii,iii,iv,v)+2ab(ii,iii,iv,v) |
Assessment Date | 2016/11/12 |
Assessor(s) | G.D. Duncan & L. von Staden |
Justification | Daubenya aurea occurs at four to five locations with an extent of occurrence (EOO) of 30 km². This species continues to decline due to ongoing expansion of crop cultivation and overgrazing, and is therefore listed as Endangered under the criterion B. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Northern Cape |
Range | It is endemic to South Africa, and is found in the Roggeveld Escarpment between Sutherland and Middelpos. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Roggeveld Karoo, Nieuwoudtville-Roggeveld Dolerite Renosterveld |
Description | This species grows in arid shrubland, on seasonally damp, red clay flats along the base of dolerite ridges. |
Threats |
| Rapid, recent expansion of cultivation of low-lying clay flats is severely threatening this highly range-restricted species. Field observations also indicate that plants are susceptible to heavy grazing. |
Population |
Daubenya aurea is locally abundant in suitable habitat.
|
Population trend | Decreasing |
