Invasive alien plants in areas of the Namib Naukluft Park disturbed by man
The occurrence of invasive alien plants in the Namib Naukluft Park in areas disturbed by the activities of man are listed. Datura innoxia, Nicotiana glauca, Prosopis spp. and Ricinus communis were the species which occurred most frequently. Most invasive plants were associated with an artificial supply of water. Datura innoxia was found primarily downstream of river fords suggesting that it has spread as a result of road building and maintenance activities. The intention of this report is to serve as a baseline for future monitoring of alien plants and to indicate which species, and which areas, require immediate management action to eradicate or prevent further spread of these plants. Keywords: Eradication of alien plants, Plant count, Modern man's activities, Conservation, Campsites, Hiking trails, Roads, Constructions, Ecological aspects, Management recommendations.
