Page 1 of 10 Original Research Invertebrates on isolated peaks in the uKhahlamba- Drakensberg Park World Heritage Site, South Africa Authors: A survey to document and describe the alpine flora and various focal faunal taxa on six 1 Adrian J. Armstrong isolated inselberg-like peaks (total area of 31.9 ha), all 3000 m or higher, located in the Robert F. Brand2 uKhahlamba-Drakensberg Park World Heritage Site, South Africa, was undertaken in early Affiliations: summer in 2005. Study of the fauna of these peaks should be informative because the impacts 1Conservation Planning of controllable anthropogenic threats on the invertebrate communities on them should be Division, Ezemvelo KZN minimal or absent in comparison with those on the main massif. A total of 341 invertebrate Wildlife, South Africa individuals representing 61 species were recorded from the focal taxa (Oligochaeta, 2Environmental, Water and Gastropoda and certain groups of Insecta, i.e. focal taxa within the Blattoidea, Dermaptera, Earth Sciences, Tshwane Orthoptera, Hemiptera, Diptera, Lepidoptera, Coleoptera and Hymenoptera). The 61 species University of Technology, recorded consisted of two species from the Oligochaeta, one species from the Gastropoda and South Africa 58 species from the Insecta. Eleven species (one from the Oligochaeta, ten from the Insecta) are Correspondence to: endemic and 11 species (one from the Oligochaeta, ten from the Insecta) are probably endemic Adrian Armstrong to the Drakensberg Alpine Centre, constituting 36.1% of the total species recorded. The results suggest that the Drakensberg Alpine Centre (DAC), as for plants, is a centre of endemism Email:

Cluster analysis showed that the species composition of the two northern peaks, Sentinel and Eastern Buttress, clustered together, separate from a cluster formed by the Postal address: Outer Horn, Inner Horn and Dragon’s Back and from the cluster formed by the southernmost PO Box 13053, Cascades peak, Cathkin.
