Description

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
