Threats |
| The species is facing various threats in some parts of its range. These threats include competition with invasive alien species in at least 11 subpopulations. Habitat degradation due to livestock farming and abandonment of agricultural sites was observed in three subpopulations. Some subpopulations are at risk from too frequent fires, habitat loss due to agricultural crops and wood plantations, and habitat loss due to infrastructure development for human settlement, tourism, and transportation.
Water pollution is a slight continuing threat in one subpopulation, while land pollution due to agricultural waste and commercial/industrial activities is projected to be a future threat at two sites. Habitat loss due to mining extraction is an ongoing threat at three locations, and changes in native species dynamics are a continuing threat in one subpopulation.
Despite these threats, the species is still widespread and common, suggesting that the impact of these threats is likely minimal at this time. |
Population |
It is widespread in the Western Cape, occurring in more than 50 subpopulations. It is known in herbaria from over 100 collections with a date range of 1883 to 2012. It is also known from 656 recent observation records on iNaturalist. The population is locally common and not declining.
