National Status |
Status and Criteria | Least Concern |

Assessor(s) | H. Mtshali, D. McKenzie & M. Lötter |
Justification | Aloe barbertoniae is a widespread and common species (EOO 11 760 km²). In spite of more than 40% historical habitat loss, it still persists at more than 25 locations, and does not at present meet any of the criteria thresholds indicating high risk of extinction. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Limpopo, Mpumalanga |
Range | Mpumalanga and Limpopo Lowveld between Tzaneen and Barberton. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Legogote Sour Bushveld, Tzaneen Sour Bushveld, Granite Lowveld, Malelane Mountain Bushveld, Pretoriuskop Sour Bushveld |
Description | Open grassland to bushy slopes, and river valleys. |
Threats |
| Aloe barbertoniae has lost about 44% of its habitat, predominantly to fruit orchards in the Lowveld around Barberton, Tzaneen and Nelspruit, timber plantations around White River, as well as urban expansion around Nelspruit, White River and Bushbuckridge. Habitat loss however occurred over a period longer than three generations, and therefore a population reduction of more than 30% within three generations can not be inferred. Habitat loss and degradation is ongoing, particularly due to expanding rural settlements between White River and Tzaneen, but Aloe barbertoniae is still very common, and not considered to be in danger of extinction at present (M. Lötter, D. McKenzie pers. comm. 2019). |
Population |
Aloe barbertoniae is abundant, with subpopulations typically consisting of several hundred to thousands of individuals. At least one subpopulation has more than 10 000 mature individuals (D. McKenzie pers. comm. 2019). Recent field observations recorded it still present at 25 locations.
