AbstractThe ecological effects of invasive alien species are often irreversible and once established, invasive species are extremely difficult and costly to control or eradicate. The threat of invasive alien species varies considerably, based on the invading species in question, the extent of the invasion, and the vulnerability of the ecosystem being invaded. Although there is a rapidly growing body of research into the effects of invasive alien plant species on insects, there has been very little research on the impacts of invasive alien plant species directly on ants and spiders. This study will investigate the response of ant and spider assemblages to invasive alien species and their clearance in three small catchments in Mooketsi, Limpopo Province, South Africa. Sampling will be consisting of ten replicated pitfall samples in three small catchments under different treatment regimes, viz. natural, cleared and invaded. This study will identify further research and conservation priorities in the area ADIS, J. 1979. Problems of interpreting arthropod sampling with pitfall traps. Zool. Anz. 202: 177-184.
