Scientific Name | Delosperma mahonii (N.E.Br.) N.E.Br. |
Higher Classification | Dicotyledons |
Family | AIZOACEAE |
Synonyms | Mesembryanthemum mahonii N.E.Br. |
National Status |
Status and Criteria | Least Concern |
Assessment Date | 2017/08/21 |
Assessor(s) | L. von Staden |
Justification | Delosperma mahonii is a widespread but poorly known species. It has been rarely recorded, but is suspected to be overlooked, rather than rare or threatened. |
Distribution |
Endemism | Not endemic to South Africa |
Provincial distribution | Gauteng, Limpopo, Mpumalanga, North West |
Range | This species is widespread across northern South Africa, extending to Zimbabwe and Mozambique. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Makhado Sweet Bushveld, Tzaneen Sour Bushveld, Kaalrug Mountain Bushveld, Gold Reef Mountain Bushveld, Sekhukhune Mountain Bushveld, Ohrigstad Mountain Bushveld, Mamabolo Mountain Bushveld, Central Sandy Bushveld, Andesite Mountain Bushveld |
Description | It occurs in rock crevices and in sandy soils in mopane woodland and grassland. |
Threats |
| According to Hartmann (2001), D. mahonii is resilient to disturbance. The species is possibly threatened by habitat loss to urban expansion in Gauteng, where it was last recorded in 1951. Threats elsewhere in its range are not known. Field surveys are needed to better document the distribution and abundance of this species in South Africa. |
Population |
According to Hartmann (2001), D. mahonii is common in Mopane woodland in Zimbabwe. Although the species is widespread across northern South Africa, it has been rarely recorded. It is possibly overlooked due to taxonomic confusion within Delosperma.
|
Population trend | Stable |
Notes |
| The genus Delosperma is taxonomically problematic and in need of revision (Chesselet et al. 1995). This means that many species are difficult to identify with confidence, resulting in an underestimation of their distribution range and abundance. |
