Justification
EOO ranging from 4437-6762 km², 32-35 severely fragmented sub-populations remain after >70% of this species' habitat has been lost to agricultural and urban expansion. It continues to decline due to too infrequent fire, quarrying, ongoing agricultural expansion and invasive alien plant infestation.
Distribution
Endemism
South African endemic
Provincial distribution
Western Cape
Range
Hopefield, Paardeberg, Tulbagh to Hottentots Holland Mountains.
Habitat and Ecology
Major system
Terrestrial
Major habitats
Swartland Shale Renosterveld, Swartland Granite Renosterveld, Swartland Silcrete Renosterveld, Cape Winelands Shale Fynbos, Boland Granite Fynbos, Cape Flats Sand Fynbos, Western Rûens Shale Renosterveld, Peninsula Granite Fynbos, Swartland Alluvium Fynbos, Breede Alluvium Fynbos
Description
Renosterveld-fynbos mosaic.
Threats
Habitat degradation due to urban development, invasive alien plants, historical and ongoing habitat loss to crop cultivation, quarrying and poor fire management has caused reduction in the population of this species as it is a reseeder that depends on fires for regeneration. Two localities have been lots to urban development resulting in a reduction the sizes of subpopulations at these sites.
