| Scientific Name | Cliffortia tenuis Weim. | Higher Classification | Dicotyledons | Family | ROSACEAE |
National Status | Status and Criteria | Vulnerable A2ac; B1ab(ii,iii,v)+2ab(ii,iii,v) | Assessment Date | 2007/03/27 | Assessor(s) | N.A. Helme, C.M. Whitehouse & D. Raimondo | Justification | A population reduction of at least 30% in the past 120 years is estimated based on >30% habitat loss to crop cultivation (generation length >50 years) EOO 1742 km², AOO <1742 km², six remaining locations continue to decline due to ongoing habitat loss to vineyard expansion and protea cultivation. |
Distribution | Endemism | South African endemic | Provincial distribution | Western Cape | Range | Elim Flats. |
Habitat and Ecology | Major system | Terrestrial | Major habitats | Elim Ferricrete Fynbos, Agulhas Sand Fynbos | Description | Lowland clays, often seasonally wet. |
Threats | | At least 30% of this species' low-lying laterite soil habitat has been ploughed for vineyard and protea cultivation in the past 80 years. Remaining plants continue to decline due to ongoing habitat loss to agricultural expansion and competition from alien invasive plants. |
Population | Population trend | Decreasing |
Conservation | | Not currently conserved in any formally protected area. |
