Higher Classification | Dicotyledons |
Family | AIZOACEAE |
Synonyms | Astridia latisepala L.Bolus, Astridia vanbredai L.Bolus, Mesembryanthemum longifolium L.Bolus, Ruschia jacobseniana L.Bolus, Ruschia longifolia (L.Bolus) L.Bolus |
National Status |
Status and Criteria | Endangered B1ab(iii,v)+2ab(iii,v) |
Assessment Date | 2015/06/10 |
Assessor(s) | D. Raimondo & P.C.V. Van Wyk |
Justification | A range-restricted species (EOO 267 km²), known from five locations and declining as a result of overgrazing and trampling. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Northern Cape |
Range | Northern Richtersveld. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Northern Richtersveld Scorpionstailveld, Central Richtersveld Mountain Shrubland, Western Gariep Hills Desert, Noms Mountain Desert |
Description | Rocky slopes. |
Threats |
| Severe overstocking of communally owned rangelands have led to extensive degradation of this species habitat. Overgrazing and trampling is so severe, it has led to a loss of shrub cover, on which many succulent species such as this one are dependent for shelter from hot desert conditions. |
Population |
Population trend | Decreasing |
Notes |
| A specimen collected from Namibia in the Sperrgebiet (Kurzweil HK 1166 in Bolus Herbarium) may belong to this taxon but the identification can not be confirmed, thus at this stage this taxon is considered a South African endemic. |
