Assessment Date | 2015/12/08 |
Assessor(s) | L. von Staden |
Justification | EOO 4641 km², plants at six known locations continue to decline due to ongoing habitat loss and degradation. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Worcester and Robertson to Riversdale. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Breede Shale Renosterveld, Eastern Rûens Shale Renosterveld, Central Rûens Shale Renosterveld |
Description | Gravel slopes in renosterveld. |
Threats |
| Lowland renosterveld within this species' known range has been extensively lost to crop cultivation. Remaining fragments continue to be degraded, particularly due to overgrazing as a result of overstocking of livestock, as well as fire exclusion. It is also threatened by urban expansion around Worcester and Riversdale. |
Population |
A rare and very poorly known taxon. Most records are old and have imprecise locality descriptions. The genus Antimima is in need of revision and species are difficult to identify. However, considering that more than 80% of this species' habitat has already been lost to agriculture, it is highly likely to be in danger of extinction even if it is found to be more common. Surveys are needed to confirm the number of remaining subpopulations.
