Justification | Brachystelma oianthum is a widespread species with an extent of occurrence (EOO) of 70 062 km² and is known from more than 10 locations. It is declining due to ongoing habitat loss, but is not yet in danger of extinction, and is therefore listed as Least Concern. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Gauteng, Limpopo, Mpumalanga, North West |
Range | This species is endemic and widespread across the high-lying areas of northern South Africa. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Wolkberg Dolomite Grassland, Northern Escarpment Quartzite Sourveld, Carletonville Dolomite Grassland, Waterberg-Magaliesberg Summit Sourveld, Rand Highveld Grassland, Tsakane Clay Grassland, Soutpansberg Summit Sourveld, Woodbush Granite Grassland, Northern Escarpment Dolomite Grassland |
Description | It occurs in rocky outcrops in montane areas. |
Threats |
Brachystelma oianthum has lost habitat to urban expansion in Gauteng and around Nelspruit. On the Limpopo and Mpumalanga Drakensberg Escarpment, it has declined due to habitat loss to timber plantations. About 40% of its habitat has been irreversibly modified, and loss continues. |
Population |
This is a rarely recorded species, and is known from scattered records. Plants are cryptic and easily overlooked when not in flower. It can be locally common in suitable habitat (Dyer 1983), but more often occurs as scattered individuals.
