Scientific Name | Eriospermum crispum P.L.Perry |
Higher Classification | Monocotyledons |
Family | RUSCACEAE |
National Status |
Status and Criteria | Vulnerable A2c; C1 |
Assessment Date | 2009/08/01 |
Assessor(s) | J.H. Vlok & D. Raimondo |
Justification | Restricted to the Calitzdorp area, where there is ongoing degradation and fragmentation of its habitat as a result of ostrich farming. There are fewer than 10 000 plants as subpopulations consist of very few plants each. There has been an estimated 30% decline in the population over the past 100 years (generation length suspected to be 50 years for this very slow growing geophytic species). |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Calitzdorp. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Eastern Little Karoo |
Description | Eastern Little Karoo on clay soils derived from shale. |
Threats |
Habitat loss and degradation as a result of ostrich farming. Ostriches are generally kept in high concentrations which cause the complete destruction of natural vegetation. In addition, at least 30% of this species' habitat has already been lost to crop cultivation, and 49% is severely grazed. |
Population |
Population trend | Decreasing |
