Scientific Name | Bulbine vitrea G.Will. & Baijnath |
Higher Classification | Monocotyledons |
Family | ASPHODELACEAE |
National Status |
Status and Criteria | Vulnerable D2 |
Assessment Date | 2015/07/13 |
Assessor(s) | P.C.V. Van Wyk & D. Raimondo |
Justification | A rare, range-restricted (EOO <300 km²) endemic to the Richtersveld, known from two locations, but likely to be under-sampled. It is potentially threatened by collection of wild individuals for the specialist horticultural trade. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Northern Cape |
Range | Mountains of the southern Richtersveld between Eksteenfontein and Port Nolloth. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Vyftienmyl se Berge Succulent Shrubland, Kahams Mountain Desert |
Description | Cracks and shelves on vertical, east-facing quartzitic cliffs. |
Threats |
| Unusual Bulbine species such as this one are often popular with plant collectors, and there is evidence of illegal collecting at at least one of this species' known locations, but it is uncertain whether it is specifically targeted. Habitat degradation due to overgrazing is the other main threat to plant species in the Richtersveld, but this species' habitat is inaccessible to livestock, and therefore safe from the effects of overgrazing and trampling. |
Population |
This species is known from only two locations 64 km apart, but is possibly overlooked, as its habitat is mostly in areas difficult to access.
|
Population trend | Stable |
Conservation |
| Richtersveld National Park. |
