Justification | A widespread species, EOO 850,000 km² that has undergone decline since 2001 as a result of indiscriminate harvesting for its appetite suppressant properties. International and national demand was particularly high between 2004 and 2006 and as a result of the high economic value of this species even remote areas of its distribution range are suspected to have been harvested. Unfortunately data do not exist to quantify the degree of decline to the population and as this species is widespread and can be locally common it is not possible to estimate overall population decline. Research on population recovery post harvesting and degree of impact of the harvesting over the past 10 years is required before this species can be accurately assessed. |

Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Tanqua Escarpment Shrubland, Hantam Karoo, Bushmanland Inselberg Shrubland, Northern Knersvlakte Vygieveld, Northern Upper Karoo, Upper Karoo Hardeveld, Gamka Karoo, Bushmanland Basin Shrubland, Kalahari Karroid Shrubland, Bushmanland Arid Grassland, Western Gariep Hills Desert, Eastern Gariep Rocky Desert, Tanqua Wash Riviere |
Description | Occurs in a wide variety of arid habitats from coastal to mountainous, also on gentle to steep shale ridges, found from dry, rocky places to sandy spots in riverbeds. |
Threats |
This species has undergone severe decline since 2001 as a result of harvesting for its appetite suppressant properties. International and national demand was particularly high in between 2004 and 2006. At this time the price range between R500 and R1200 per kilogram, as a result of the very high value of this species we suspect that even remote areas of its distribution range were harvested (Wynberg and Newton pers. comm.). Unfortunately data do not exist to quantify the decline the population. As a result of a decrease in demand for Hoodia internationally and the strict enforcement of new legislation to protect this species wild harvesting has declined in South Africa. |
