Scientific Name | Senecio dregeanus DC. |
Higher Classification | Dicotyledons |
Family | ASTERACEAE |
National Status |
Status and Criteria | Vulnerable B1ab(iii)+2ab(iii) |
Assessment Date | 2008/06/25 |
Assessor(s) | L. von Staden |
Justification | EOO 6880 km², AOO (based on remaining untransformed grasslands within the known range) <1500 km². It probably occurs at less than 10 locations, based on herbarium records and habitat maps. At least 67% of its grassland habitat has been transformed, and all remaining subpopulations are on small habitat fragments that are subject to ongoing degradation as a result of frequent fires, overgrazing, subsistence agriculture and the effects of fragmentation. Habitat loss has taken place over a period longer than three generations. Data on population size and trends are urgently needed. |
