Land- und Forstwirtschaft
The need for this study to be undertaken arose because of a dramatic increase in export figures during 1998 and 1999 and corresponding concerns regarding the possible overutilisation of Devil’s Claw in Namibia.
Federal Agency for Nature Conservation
The objectives of the study focussed on three main aspects:
- To investigate the influence of highly variable annual rainfall on Devil’s Claw populations and the impact of harvesting thereon
- To develop a simple and reliable method to establish an annual Devil’s Claw harvesting quota for potential harvesting areas
- To establish a sustainable harvesting method and make recommendations for more effective management of Devil’s Claw
