National Status |
Status and Criteria | Critically Endangered (Possibly Extinct) |
Assessment Date | 2017/08/21 |
Assessor(s) | L. von Staden |
Justification | Delosperma hollandii is a localized species last recorded in 1950. It is possibly locally extinct due to habitat loss to urban and industrial expansion, but field surveys are needed to confirm this. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Eastern Cape |
Range | This species is known from a small area in the Eastern Cape, between Uitenhage and Port Elizabeth. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Sundays Valley Thicket |
Description | Its habitat is unknown, it possibly occurs on coastal flats. |
Threats |
| Natural vegetation in area where this species is recorded from continues to be lost and degraded due to urban and industrial development, as well as spreading informal settlements. Very little remains intact, and these areas need to be surveyed to relocate this species in the wild. |
Population |
This species is known from a few collections from within a very small area along the Swartkops River between Uitenhage and Port Elizabeth. It was last recorded in 1950. It may be overlooked due to taxonomic problems within Delosperma, but may also be very rare or even possibly extinct due to habitat degradation and destruction.
