Scientific Name | Cliffortia ferricola C.M.Whitehouse |
Higher Classification | Dicotyledons |
Family | ROSACEAE |
National Status |
Status and Criteria | Critically Endangered A2c; B1ab(ii,iii,v)+2ab(ii,iii,v) |
Assessment Date | 2007/12/14 |
Assessor(s) | N.A. Helme, C.M. Whitehouse & D. Raimondo |
Justification | Although this is a recently discovered species, a past population reduction of at least 80% is suspected based on >95% habitat loss to crop cultivation and urban expansion in the past 100 years (generation length >50 years). EOO 20 km², AOO <5 km², three isolated, severely fragmented remaining subpopulations is expected to continue to decline due to infrastructure development and alien plant invasion. 10% of one subpopulation is to be lost to the development of a polo field. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Bot River to Bot River Vlei. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Western Ruens Shale Renosterveld, Ruens Silcrete Renosterveld, Kogelberg Sandstone Fynbos, Elim Ferricrete Fynbos, Hangklip Sand Fynbos |
Description | Ferricrete gravels with associated shale and acid sand. |
Threats |
| More than 95% of this species' habitat is already transformed and degraded due to agricultural expansion, urban development and alien plant invasion. Remaining subpopulations are threatened by infrastructure development, road construction, quarrying and competition from unmanaged alien invasive plants. |
