National Status |
Status and Criteria | Vulnerable D2 |
Assessment Date | 2023/08/15 |
Assessor(s) | H. Mtshali |
Justification | A range-restricted endemic to Mossel Bay District, South Africa. It has an area of occupancy (AOO) of 16 km², and is potentially threatened by illegal, indiscriminate succulent collection and agriculture. It is therefore listed as Vulnerable. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | This species has a restricted distribution in Mossel Bay District. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Gouritz Valley Thicket |
Description | It occurs on soils derived from shales, limestone, and conglomerate of the Bredasdorp Formation. |
Threats |
| Although direct threats to this species are currently unknown, the Gasteria genus is in high demand in the international horticultural trade. It remains potentially threatened by opportunistic, indiscriminate succulent collecting, especially given the increase in trade in succulent species. Furthermore, all the known subpopulations are found near agricultural fields and expansion of agricultural sites may become a potential threat. |
Population |
It is known from four subpopulations, and one was recorded to have between 10 and 50 plants in 2012. The population trend and size are unknown, but it is suspected to be declining due to illegal harvesting.
