| Scientific Name | Ruschia langebaanensis L.Bolus | Higher Classification | Dicotyledons | Family | AIZOACEAE |
National Status | Status and Criteria | Vulnerable B1ab(i,ii,iii,iv,v)+2ab(i,ii,iii,iv,v) | Assessment Date | 2016/01/13 | Assessor(s) | N.A. Helme & L. von Staden | Justification | EOO 1075 km², 10 remaining locations continue to decline due to ongoing habitat loss and degradation. |
Distribution | Endemism | South African endemic | Provincial distribution | Western Cape | Range | Vredenburg Peninsula to Yzerfontein. |
Habitat and Ecology | Major system | Terrestrial | Major habitats | Saldanha Flats Strandveld, Saldanha Granite Strandveld, Swartland Granite Renosterveld | Description | Granite outcrops near the coast. |
Threats | | Most of this species' habitat has been converted to crop fields in the past. Remaining subpopulations are severely threatened by ongoing habitat loss to coastal development. In addition some sites are becoming more and more degraded due to overgrazing and inappropriate fire management. |
Population | The population has been fragmented by extensive past habitat loss to crop cultivation, and remains in a few isolated subpopulations. Field surveys indicate that at least two subpopulations are small, consisting of fewer than 100 mature individuals, while other records describe the species as locally common. It is therefore not possible to estimate whether the population is severely fragmented. This species could possibly qualify for a higher threat category if more field surveys were to indicate that most subpopulations are small and isolated.
