Higher Classification | Monocotyledons |
Family | AMARYLLIDACEAE |
National Status |
Status and Criteria | Critically Endangered B1ab(iii,v)+2ab(iii,v) |
Assessment Date | 2015/09/20 |
Assessor(s) | D.A. Snijman & L. von Staden |
Justification | EOO 48 km², between seven and nine subpopulations remain. All are small, with more than 50% of subpopulations confined to isolated fragments, and declining due to ongoing habitat loss and degradation. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Swellendam to Buffeljagsrivier. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Ruens Silcrete Renosterveld, Swellendam Silcrete Fynbos |
Description | Pebble-strewn loamy soils in Swellendam Silcrete Fynbos. |
Threats |
| Less than 50% of this species' habitat remains intact, predominantly after losses to agricultural expansion. It continues to be threatened by urban expansion around Swellendam, and further expansion of crop fields around Buffeljagsrivier. |
Population |
Recent field observations indicate that there are between seven and nine remaining subpopulations of this species, the largest consisting of between 50 and 100 mature individuals, and six of these are confined to isolated fragments and road verges. The population is estimated to number fewer than 700 mature individuals and continues to decline due to ongoing habitat loss and degradation.
