National Status |
Status and Criteria | Vulnerable B1ab(i,ii,iii,iv,v) |
Assessment Date | 2016/10/24 |
Assessor(s) | N.A. Helme & L. von Staden |
Justification | A widespread (EOO 16 389 km²), but extremely rare species known from 10 locations. It continues to decline due to ongoing habitat loss and degradation. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Northern Cape, Western Cape |
Range | Bokkeveld Escarpment to Caledon. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Swartland Shale Renosterveld, Matjiesfontein Shale Renosterveld, Ceres Shale Renosterveld, Western Ruens Shale Renosterveld, Vanrhynsdorp Shale Renosterveld, Swartland Granite Renosterveld, Bokkeveld Sandstone Fynbos, Northern Inland Shale Band Vegetation |
Description | Shale renosterveld, occasionally in deep loamy soils in sandstone fynbos. |
Threats |
| This species is threatened by ongoing habitat loss to agricultural expansion on the Bokkeveld Escarpment, Swartland, Overberg and Warm Bokkeveld east of Ceres. Particularly in the Swartland and western Overberg, <5% of renosterveld remains intact, and in these areas the species is confined to very small, isolated remnants of natural vegetation. A subpopulation near Durbanville is threatened by habitat loss to urban expansion and competition from alien invasive plants. |
Population |
Perdicium capense is a widespread, but extremely rarely recorded species, currently known from 10 widely scattered locations. It is most often recorded in recently burnt vegetation, and may be overlooked in dense, mature renosterveld. In many small renosterveld remnants fire is excluded, which means that this species could be easily overlooked in surveys. Field observations indicate continuing decline due to ongoing habitat loss.
