Higher Classification | Dicotyledons |
Family | GERANIACEAE |
National Status |
Status and Criteria | Endangered B1ab(ii,iii,iv,v)+2ab(ii,iii,iv,v) |
Assessment Date | 2018/10/05 |
Assessor(s) | N.A. Helme, D. Raimondo & L. von Staden |
Justification | Pelargonium nephrophyllum has an extent of occurrence (EOO) and an area of occupancy (AOO) of 11 km². Five known remaining locations are declining due to ongoing habitat loss for vineyard and wheat cultivation. It is therefore listed as Endangered under criterion B. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | This species is endemic to South Africa, and is found in flats southeast of Vanrhynsdorp. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Klawer Sandy Shrubland |
Description | It occurs in succulent karoo, on sandy and stony lower slopes and flats, which become temporarily inundated during infrequent heavy winter rainfall. |
Threats |
| This highly range-restricted species' habitat is impacted by crop cultivation and livestock grazing, 33% has already been ploughed, and significant loss continues (8% was lost between 1990 and 2014). One of the largest subpopulations, of the few known, was recently ploughed and turned into a wheat field (Craib 2001). |
