Higher Classification | Monocotyledons |
Family | ASPHODELACEAE |
National Status |
Status and Criteria | Vulnerable B1ab(iii,v)+2ab(iii,v) |
Assessment Date | 2014/08/09 |
Assessor(s) | E. Marinus & D. Raimondo |
Justification | A range restrcited endemic to the Bokkeveld Escarpment of the Northern Cape (EOO <53 km²). More than 80% of this taxon's habitat has been lost to wheat and pasture cultivation since 1940. Plants are very sensitive to disturbance, trampling and livestock grazing and there is an ongoing decline in numbers of mature individuals and habitat quality as a result of livestock grazing. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Northern Cape |
Range | Bokkeveld Escarpment. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Nieuwoudtville Shale Renosterveld |
Description | Renosterveld, clay soils in flat, tillite-shale areas. |
Threats |
| Agricultural expansion has significantly reduced this species' habitat. This threat has largely ceased, as remaining areas are generally unsuitable for cultivation. However, these fragments are severely overstocked with livestock, and overgrazing and trampling is causing ongoing degradation. |
Population |
As a result of habitat loss exceeding 80%, it is likely that this species has undergone a large population reduction. However, agricultural expansion started in the 1940s, which is outside the three generation threshold for this presumably relatively short-lived species. At present, ten subpopulations remain on small remnant patches of renosterveld vegetation on road verges and in fragments of natural vegetation left between cultivated fields. As each of these fragments is independently owned and experiences different farming practises, each subpopulation represents a separate location. Not enough information is available to determine if subpopulations are small enough for this species to qualify as severely fragmented. Although some subpopulations are small a number are few are large and have a couple of hundred individuals.
