Assessor(s) | D. Raimondo |
Justification | EOO 128 km², there are less than seven locations known, which are declining as a result of Rooibos tea cultivation. More than 30% of its habitat has been lost in the past 15 years (generation length 10 years), with the majority lost in the past five years. The continuing expansion of the Rooibos tea market means that the pressure on this species' habitat will likely worsen. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Northern Cape |
Range | Bokkeveld Mountains. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Nardouw Sandstone Fynbos, Bokkeveld Sandstone Fynbos |
Description | Deep, sandstone-derived sands on gentle slopes and flats, between rocks. |
Threats |
| Habitat loss to rooibos tea cultivation is a severe, ongoing threat to this localized species, with more than 30% of its habitat already transformed, the majority in the past 5 years. The continuing expansion of the Rooibos tea market means that the pressure on this species' habitat will continue. |
