Justification | Seven of 14 locations have been lost to crop cultivation and urban expansion over the past 100 years, and over 90% of its EOO has been transformed. The remaining seven locations are severely fragmented across a large range (EOO 15 000 km²). |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Citrusdal to Gordon's Bay. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Swartland Shale Renosterveld, Cape Flats Sand Fynbos, Lourensford Alluvium Fynbos, Swartland Alluvium Fynbos |
Description | Seasonally inundated clay flats. |
Threats |
Agriculture was a severe past threat with over 90% of its habitat lost to crop cultivation in the past 70 years. Decline due to cultivation is ongoing but moderate.
Urban expansion was a severe past threat. Many of the extinct locations are from the Strand, Cape Flats and Paarl areas. Seasonally wet flats at Harmony flats in the Strand area have experienced 50% loss of habitat in the past three years to development. Development is also an ongoing threat around Faure and Gordon's Bay. |
