Higher Classification | Dicotyledons |
Family | ACANTHACEAE |
National Status |
Status and Criteria | Vulnerable D2 |
Assessment Date | 2023/02/07 |
Assessor(s) | H.M. Steyn & L. von Staden |
Justification | A localized taxon, known from one location where it is potentially threatened by habitat loss and degradation. It is assessed as Vulnerable under criterion D2. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Northern Cape |
Range | This taxon occurs in Namaqualand, between Kleinsee and Springbok. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Namaqualand Heuweltjieveld |
Description | It grows on sandy plains in Namaqualand Heuweltjieveld. |
Threats |
| There is extensive open-cast mining in the area where this taxon occurs, and it is potentially threatened by habitat loss to mining. Large parts of Namaqualand are also heavily overstocked with livestock, which is causing ongoing degradation of arid shrublands. Grazing did not appear to impact the population in 2016, however, it is uncertain what the status of the population will be after the severe droughts of the past few years. |
Population |
This taxon was discovered in 2015 and is currently known from a single, small, but healthy subpopulation. It is likely that other, still undiscovered subpopulations exist, as its habitat is still relatively poorly explored. It is however unlikely to be widespread and common, as no other collections of this taxon are known.
