Scientific Name | Pelargonium ternifolium Vorster |
Higher Classification | Dicotyledons |
Family | GERANIACEAE |
Synonyms | Pelargonium trifoliatum Harv. |
National Status |
Status and Criteria | Near Threatened A2bc; B1ab(iii)+2ab(iii) |
Assessment Date | 2011/06/11 |
Assessor(s) | D. Raimondo & D.A. Kamundi |
Justification | EOO 2 242 km², less than 20 locations remain after at least 20% of this species' habitat has been transformed for wheat cultivation and vineyard expansion over the past 90 years (generation length 20-30 years). Decline due to habitat degradation from invasive alien plants and poor fire management is ongoing. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Moorreesburg to Stellenbosch. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Swartland Shale Renosterveld, Breede Shale Renosterveld, Swartland Granite Renosterveld, Swartland Silcrete Renosterveld, Swartland Alluvium Renosterveld, Piketberg Sandstone Fynbos, Hawequas Sandstone Fynbos, Cape Winelands Shale Fynbos, Breede Shale Fynbos, Boland Granite Fynbos, Cape Flats Sand Fynbos, Atlantis Sand Fynbos, Swartland Alluvium Fynbos, Breede Alluvium Fynbos |
Description | Dry renosterveld to wet fynbos over a wide range of altitudes. |
Threats |
| Renosterveld subpopulations have been impacted by wheat and vineyard cultivation, this species is highly likely to have lost a minimum of 20% of its habitat in the past 80 years. Many remaining subpopulations are threatened by invasive alien plants as well and too infrequent fires. |
Population |
Not enough is known about the population size of this species, but it is suspected that subpopulations are small. This species may qualify for a higher category under Criterion C if more population data could be obtained.
