Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Swartruggens Quartzite Karoo, Doringrivier Quartzite Karoo, Namaqualand Blomveld, Cape Flats Dune Strandveld, Langebaan Dune Strandveld, Saldanha Flats Strandveld, Lambert's Bay Strandveld, Cederberg Sandstone Fynbos, Bokkeveld Sandstone Fynbos, Cape Flats Sand Fynbos, Atlantis Sand Fynbos, Hopefield Sand Fynbos, Leipoldtville Sand Fynbos, Namaqualand Sand Fynbos, Swellendam Silcrete Fynbos |
Description | Deep sandy flats. |
Threats |
Habitat loss to potato cultivation is causing ongoing decline in subpopulations in the Sandveld around Hopefield, and alien invasive plants are threatening subpopulations throughout the range. Coastal development between Blouberg Strand and Yzerfontein is also likely to be causing population decline. |
