Status and Criteria | Vulnerable B1ab(ii,iii,iv,v)+2ab(ii,iii,iv,v) |
Assessment Date | 2012/11/29 |
Assessor(s) | N.A. Helme, K.C. Oberlander & D. Raimondo |
Justification | EOO 141 km², AOO <50 km², fewer than 10 remaining locations of this range-restricted species continue to decline due to ongoing habitat loss to housing developments and crop cultivation. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Hopefield to Paternoster. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Saldanha Granite Strandveld, Hopefield Sand Fynbos |
Description | Shale soils transitioning into acid sands. |
Threats |
Threatened by ongoing habitat loss to urban expansion, at least one subpopulation was recently lost to a low cost housing development between 2000 and 2006. Crop cultivation was a severe past threat, as this species is associated with nutrient rich soils transitions with acid sands much of its habitat has been targeted for crops. Loss due to expanding crop cultivation is ongoing in parts of its range. |
