Higher Classification | Monocotyledons |
Family | ASPHODELACEAE |
National Status |
Status and Criteria | Vulnerable D2 |
Assessment Date | 2011/05/31 |
Assessor(s) | D. Raimondo & N.A. Helme |
Justification | AOO <15 km², known from only three locations, this species has lost over 80% of its habitat to wheat cultivation in the past. Further habitat loss to wheat cultivation remains a potential threat. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Northern Cape |
Range | Nieuwoudtville. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Nieuwoudtville Shale Renosterveld, Nieuwoudtville-Roggeveld Dolerite Renosterveld, Bokkeveld Sandstone Fynbos |
Description | Transition soils between dolerite clays and Dwyka tillite. |
Threats |
| Crop cultivation is a past threat to this species, more than 50% of the transition soils between dolerite and tillite have been transformed to wheat and pasture over the past 70 years. Transformation for wheat cultivation is not ongoing, but does happen sporadically especially after land changes hands. |
Population |
Three subpopulations are known. This species is not declining at present.
|
Population trend | Stable |
