Scientific Name | Haemanthus graniticus Snijman |
Higher Classification | Monocotyledons |
Family | AMARYLLIDACEAE |
National Status |
Status and Criteria | Endangered B1ab(iii,v)+2ab(iii,v); C2a(i) |
Assessment Date | 2022/02/01 |

Justification | This species has a limited distribution range with an area of occupancy (AOO) of 32 km² and an extent of occurrence (EOO) of 802 km². It is known from between four and six locations. The subpopulations are small, with typically less than 50 plants per subpopulation, and the overall population numbers are fewer than 1000 mature individuals. At least 13% of this species' habitat has been lost in the past due to ploughing for crops and illegal collecting for the horticultural trade has resulted in further declines to the population. It therefore qualifies for listing as Endangered under criteria B and C. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Northern Cape |
Range | It has a restricted distribution in the Northern Cape Province of South Africa, where it occurs from Springbok to Kamiesberg. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Namaqualand Granite Renosterveld |
Description | Plants grow near seasonal watercourses in coarse, granite-derived soils. |
Threats |
| This species is threatened by habitat degradation as a result of ploughing, particularly for the Kamiesberg subpopulations. It is also threatened by illegal collection. |
Population |
The population is estimated to be less than 1000 plants, with fewer than 10 plants typically seen per subpopulation and no subpopulation recorded to have more than 50 mature individuals. However, this species is quite inconspicuous and may be under-recorded. Populations consist of clumps of bulbs scattered along seasonal watercourses. In Kamiesberg, along the streams, less than 50 individuals were reported, and four plants were reported in Grootvlei. The population is inferred to be declining as a result of illegal collection and ongoing habitat degradation.
