National Status
Status and Criteria
Endangered B1ab(iii)+2ab(iii)
Assessment Date
J.C. Manning, D. Raimondo & L. von Staden
A rare, range-restricted species (EOO <113 km²), known from fewer than five locations and declining due to ongoing habitat loss to agricultural expansion.
South African endemic
Provincial distribution
Western Cape
Breede River Valley between Worcester and Robertson.
Habitat and Ecology
Major system
Major habitats
Robertson Karoo, Breede Alluvium Renosterveld, Breede Sand Fynbos
Succulent karoo, in washes on sandstone-shale transition.
Threatened by ongoing habitat loss to expanding olive orchards and vineyards. This species' habitat is already more than 50% transformed, and loss is continuing.

Freesia marginata occurs in small subpopulations on fragments among expanding orchards and vineyards. One subpopulation has fewer than 100 plants (J.C. Manning, pers. obs.), and at least one other subpopulation has been observed nearby, but no estimate of population size was made. It is possible that more plants occur on other fragments in this area, and surveys are needed to determine the full extent of this species' range.
