Assessor(s)
N.A. Helme, J.B.P. Beyers & D. Raimondo
Justification
EOO 9000 km², known from less than 10 locations. It has lost much of its habitat in the past, but over a period greater than three generations. There is ongoing habitat loss mainly due alien plant invasion, urban expansion and crop cultivation (vines).
Distribution
Endemism
South African endemic
Provincial distribution
Western Cape
Range
Darling to Cape Peninsula to Somerset West, and Twenty-four Rivers Mountains to Wolseley and Franschhoek Mountains.
Habitat and Ecology
Major system
Terrestrial
Major habitats
Swartland Granite Renosterveld, Swartland Silcrete Renosterveld, Peninsula Sandstone Fynbos, Olifants Sandstone Fynbos, Hawequas Sandstone Fynbos, Peninsula Granite Fynbos, Boland Granite Fynbos, Breede Sand Fynbos, Cape Flats Sand Fynbos, Atlantis Sand Fynbos, Swartland Alluvium Fynbos, Breede Alluvium Fynbos
Description
Sandy flats and sandy areas on lower mountain slopes.
Threats
N.A. Helme (2006) noted invasive alien species and urban development as main threats to this species. Agriculture (wheat farming) is a severe past threat and most subpopulations on the west coast were lost to wheat farming. Majority of ploughing took place pre 1960s which is more than 3 generations ago (D. Raimondo). Agriculture, especially vines is an ongoing threat to this species throughout its range. Urbanisation is a severe past threat; most of the cape flats subpopulations were lost and there is only one site remaining in Kenilworth race course. Most of this lost took place between 1910 - 1960 which is more than 3 generations ago (D. Raimondo).
