Higher Classification | Dicotyledons |
Family | MALVACEAE |
Synonyms | Hermannia cavanillesiana Eckl. & Zeyh. (in part) |
National Status |
Status and Criteria | Vulnerable A2c |
Assessment Date | 2018/10/05 |
Assessor(s) | L. von Staden |
Justification | Hermannia lavandulifolia is a widespread and common species that 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. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | This species is endemic to the Western Cape, 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 | Terrestrial |
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 Strandveld, Gouritz Valley Thicket, Goukamma Dune Thicket, Gamka Valley Thicket |
Description | It occurs on clay slopes in renosterveld and valley thicket. |
Threats |
| This species has lost nearly 80% of its habitat to crop cultivation in the past, and loss continues. It is also threatened by habitat loss to coastal development between Stilbaai and Plettenberg Day. Subpopulations on the southern Cape coast are also threatened by competition from dense infestations of alien invasive plants. |
Population |
This species 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.
