Impacts of invasive alien plants on Red-Listed South African dragonflies (Odonata)

Samways M.J. ; Taylor S. (2004)

Short Survey

This paper gives an overview of the threats to dragonflies (including damselflies) (Odonata), globally and nationally Red-Listed by the IUCN, In South Africa. All the globally Red-Listed species are endemic to South Africa. Invasive alien plants, especially Australian Acacia trees along water-courses, are by far the most important threat to these endemic species. Removal of the invasive alien trees is likely to increase considerably the prospects for the long-term survival of these species. In contrast, the nationally Red-Listed species that are not globally Red-Listed are threatened overall more by natural vagaries of weather than by invasive alien plants.
