Devil's Claw (Harpagophytum procumbens and Harpagophytum zeyheri) are plants that grow mainly in the Kalahari sands of Namibia, Botswana, South Africa and Angola, and to a lesser extent Zambia, Zimbabwe and Mozambique. Demand for Devil's Claw on the international market has increased considerably over the last decade. While this increase in demand has brought about greater opportunities for those involved in the harvesting and trading of the plant, it has also vastly increased the pressures on this resource. This is the final report on the study, "Population Dynamics and Sustainable Harvesting of the Medicinal Plant Harpagophytum procumbens DC (Devil's Claw) in Namibia". This report presents background information on key issues related to this study, the implementation and results thereof and provides recommendations for the sustainable management of Devil's Claw based on the findings of the study.
