Justification | This species has an extent of occurrence (EOO) of 14 774 km² and an area of occupancy (AOO) of 284 km². It is known from 19 locations and is still fairly widespread and common. It is threatened by incidental collecting but affected subpopulations are still stable and the loss is estimated to be less than 10%. It therefore qualifies as Least Concern. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | It is endemic to the Western Cape Province, where it is found from the Cederberg to Betty's Bay and the Riviersonderend Mountains. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Peninsula Sandstone Fynbos, Winterhoek Sandstone Fynbos, Overberg Sandstone Fynbos, Hawequas Sandstone Fynbos |
Description | It occurs in wet seepages over cliffs, seeps and along perrenial streams. |
Threats |
| It was previously heavily collected in many localities and sold in the markets of Cape Town and for export to Europe. Despite the past collecting of plants for horticultural purposes, less than 10% of the population has been lost. This species today enjoys full protection and continues to flourish along mountain streams in the western Cape (Liltved and Johnson, 2012). More than 90% of the subpopulations remain in inaccessible sites on cliffs and along waterfalls in the mountains of the Western Cape and are unaffected by collecting. The subpopulations impacted by illegal harvesting are still relatively stable and collection is thought to be incidental. Picking is not fatal unless the entire plant is collected. |
Population |
The species is widespread and common and the total population size is estimated to be more than 50 000 in over 20 subpopulations.
