Status and Criteria | Least Concern |
Assessment Date | 2015/06/30 |
Assessor(s) | L. von Staden |
Justification | A widespread and fairly common species that is however declining due to ongoing extensive habitat loss and fragmentation of lowland subpopulations. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Olifants River Valley to the Cape Peninsula and Caledon. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Fynbos |
Description | Lower slopes and flats in granite fynbos and renosterveld. |
Threats |
| This species has declined extensively on the Cape Peninsula and around Stellenbosch due to habitat loss to urban expansion and timber plantations. In the Swartland, Breede River Valley and around Caledon, its lowland habitat has been extensively reduced and fragmented due to agricultural expansion. A few subpopulations in protected montane are not currently threatened, but could be impacted if unmanaged alien invasive plants are allowed to spread further. |
Population |
This species is widespread and still common, in spite of habitat loss across parts of its range.
|
Population trend | Decreasing |
