Hermannia lavandulifolia is a widespread and common species, with an extent of occurrence (EOO) of 12 018 km². It is declining due to severe, ongoing habitat loss and degradation. Based on the observed rate of habitat loss, a population reduction of 31% over three generations is inferred. It is therefore listed as Vulnerable under criterion A.
South African endemic
Provincial distribution
Western Cape
This species is endemic to the Western Cape province of South Africa, where it occurs from Worcester to the Overberg, and extends along the southern Cape coastal lowlands as far east as Plettenberg Bay.
Habitat and Ecology
Major system
Major habitats
Groot Brak Dune Strandveld, Overberg Dune Strandveld, Breede Shale Renosterveld, Montagu Shale Renosterveld, Mossel Bay Shale Renosterveld, Eastern Ruens Shale Renosterveld, Central Ruens Shale Renosterveld, Western Ruens Shale Renosterveld, Hartenbos Dune Thicket, Gouritz Valley Thicket, Goukamma Dune Thicket, Gamka Valley Thicket
It occurs on clay slopes in renosterveld and valley thicket.
Hermannia lavandulifolia has lost nearly 80% of its habitat to crop cultivation in the past, and this loss continues. It is also threatened by habitat loss to coastal development between Stilbaai and Plettenberg Bay. Subpopulations on the southern Cape coast are also threatened by competition from dense infestations of alien invasive plants.

It is still common in spite of extensive historical habitat loss, but continues to decline. It has lost 8% of its habitat between 1990 and 2014, and based on the observed rate of loss, a population reduction of 31% over three generations (60 years) is inferred.
