Scientific Name | Conophytum tantillum N.E.Br. subsp. amicorum S.A.Hammer & Barnhill |
Higher Classification | Dicotyledons |
Family | AIZOACEAE |
National Status |
Status and Criteria | Vulnerable D1+2 |
Assessment Date | 2015/06/10 |
Assessor(s) | A.J. Young |
Justification | Known from a single subpopulation (AOO <1km²), estimated to consist of <1000 individuals. It is potentially threatened by livestock trampling and succulent collection. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Northern Cape |
Range | Steinkopf. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Namaqualand Blomveld |
Description | Vertical cliff faces, often in cracks and crevices on large quartz blocks. |
Threats |
| This taxon occurs in an accessible site close to a town. The rangelands surrounding this town are communally owned, and is being severely degraded due to overstocking. This taxon is potentially vulnerable to trampling, but some plants occurring on vertical cliffs may be inaccessible to livestock. Illegal succulent collecting is also a potential threat, as the population is accessible from a nearby road. The population is very small and localized, and therefore any loss of individuals from the wild would immediately lead to an increased risk of extinction. |
Population |
This taxon is known from a single, small localized subpopulation of less than 1000 mature individuals.
