Scientific Name | Aloe challisii Van Jaarsv. & A.E.van Wyk |
Higher Classification | Monocotyledons |
Family | ASPHODELACEAE |
National Status |
Status and Criteria | Vulnerable D2 |
Assessment Date | 2018/10/09 |
Assessor(s) | H. Mtshali, D. Raimondo, J.E. Burrows & M. Lötter |
Justification | Aloe challisii is a highly localized species, known from a single location where it is potentially threatened by succulent collecting and competition from alien invasive plants. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Mpumalanga |
Range | Aloe challisii is endemic to the Steenkampsberg, a mountain range in northern Mpumalanga Province. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Steenkampsberg Montane Grassland |
Description | Afromontane mistbelt grassland, in rock crevices among moss on upper vertical, south to southeast-facing sandstone cliffs, 1700-1800 m. |
Threats |
| Aloe species are popular with succulent collectors, and there are several documented instances of subpopulations completely cleared out by succulent collectors. Given Aloe challisii's extremely limited distribution range and small population, collecting of wild plants could rapidly increase this species' risk of extinction.
In addition, alien invasive plants are present in many areas of the Steenkampsberg, and if left unmanaged, are likely to outcompete native species. |
Population |
Population trend | Stable |
