Justification | A Bokkeveld Escarpment endemic known from an area of 800 km². It has experienced habitat loss to wheat cultivation (over 73% of its habitat was transformed in 60 years). Eriospermums are long-lived (generation length is suspected to be a minimum of 30 years). |
Distribution |
Endemism | South African endemic |
Provincial distribution | Northern Cape |
Range | Nieuwoudtville district. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Nieuwoudtville Shale Renosterveld, Nieuwoudtville-Roggeveld Dolerite Renosterveld |
Description | Dwarf karoo shrubland on hill slopes (in soils derived from the dolerite outcrops), and on flats (in clay soils derived from Dwyka tillite). |
Threats |
Experienced a past loss of habitat to wheat farming (over 73% of its habitat was transformed in the past 60 years). Eriospermums are long-lived species (generation time is a minimum of 30 years), so this loss has taken place in less than three generations. |
