National Status |
Status and Criteria | Near Threatened B1ab(i,ii,iii,iv,v) |
Assessment Date | 2020/11/30 |
Assessor(s) | L. von Staden |
Justification | This species is a range-restricted species with an extent of occurrence (EOO) of 3798 km². It is estimated to remain at between 10 and 20 locations, and it is declining due to ongoing habitat loss and degradation, as well as competition from unmanaged alien invasive plants. It almost qualifies for listing as Vulnerable under criterion B and is therefore assessed as Near Threatened. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Eastern Cape |
Range | It is endemic to South Africa, and is found from Humansdorp to Port Elizabeth. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | South Eastern Coastal Thornveld, Loerie Conglomerate Fynbos, Algoa Sandstone Fynbos, Kouga Grassy Sandstone Fynbos, Kouga Sandstone Fynbos, Southern Cape Dune Fynbos |
Description | Plants grow in seasonal seeps on lower slopes and dunes. |
Threats |
| It has declined across the southern and western parts of its range. Around Port Elizabeth, it continues to lose habitat to infrastructure development and urban expansion. On the coastal lowlands between Humansdorp and Port Elizabeth, most subpopulations known through historical records are now locally extinct due to habitat loss to agricultural expansion. On the lower southern slopes of the Van Stadens Mountains, much of this species' habitat has been converted to exotic timber plantations, and spreading, unmanaged alien invasive plants are causing ongoing degradation of remaining fynbos patches. In the Elands River Valley, competition from alien invasive plants is the main ongoing threat to subpopulations of this species. |
