Scientific Name | Annesorhiza articulata Magee |
Higher Classification | Dicotyledons |
Family | APIACEAE |
National Status |
Status and Criteria | Endangered B1ab(i,ii,iii,iv,v) |
Assessment Date | 2015/12/09 |
Assessor(s) | L. von Staden, A.R. Magee, N.A. Helme & R. Koopman |
Justification | EOO 595 km², plants at three to four remaining locations continue to decline due to ongoing habitat loss and degradation. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Porterville to Paarl. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Swartland Alluvium Fynbos |
Description | Seasonally moist clay soils in Swartland Alluvium Fynbos. |
Threats |
| This species has already lost most of its habitat to crop cultivation and urban expansion around Paarl, and only small, isolated remnants remain. These fragments continue to be lost to ongoing development, and are otherwise often poorly managed, with mowing, grazing, uncontrolled spread of alien invasive plants and inappropriate fire regimes causing ongoing degradation. |
Population |
Three small, isolated subpopulations are known to remain, the largest consisting of about 250 mature individuals. Further surveys are needed to confirm whether it still occurs in the Joostenberg area, where it is known from a historical record.
