Higher Classification | Monocotyledons |
Family | HYACINTHACEAE |
National Status |
Status and Criteria | Vulnerable D2 |
Assessment Date | 2014/04/03 |
Assessor(s) | L. von Staden & N.A. Helme |
Justification | A localized habitat specialist, known from two locations and potentially threatened by habitat degradation due to agricultural expansion and grazing. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | North-western Knersvlakte south-east of Kotzesrus. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Namaqualand Granite Renosterveld |
Description | Alkaline, seasonally inundated granitic clay pans. |
Threats |
| Much of the area surrounding the seasonal pans where this species occurs has been ploughed for crops. Although the pans are not cultivated, they are vulnerable to disruption of water flow dynamics due to modification of the surrounding area. The largest subpopulation occurs on a pan that is currently in good condition and not facing any immediate threat, but a second, smaller subpopulation is potentially threatened by habitat degradation due to grazing and trampling by livestock. |
Population |
This species is locally abundant, but very localized, with several thousand plants in the largest subpopulation, occupying a single pan of 1.5 ha. A second subpopulation of <30 plants occur in a similar, but more degraded pan about 5 km away.
