Abstract:

Adenia pechuelii, an unusual pachycaul member of the Passifloraceae family, has restricted range in the Namib Desert and was previously considered threatened on the Namibian Red Data list. The area of a planned uranium mine on farm Valencia in the central Namib Desert supports the largest population found to-date in Namibia. After an initial environmental impact assessment, the mining company commissioned a survey of the A. pechuelii population and an experiment to establish the best methodology for relocating plants. Sixty plants were transplanted to a nearby area that would remain unaffected by mining. Different treatments, including watering regimes, were applied but no significant differences were detected between any of these. All plants survived one year after transplanting and showed signs of vitality. Four years after transplanting 80% of plants were alive. The implications these findings have for the conservation and relocation of A. pechuelii are discussed. Keywords: Adenia pechuelii, population survey, restoration, Namibia, southern Africa.
