Ant species richness of fynbos and forest ecosystems in the southern Cape

J.H. Koen, W Breytenbach

Abstract


The ant fauna in fynbos and forest habitats in the southern Cape are compared. There is no significant difference in ant species richness between the two undisturbed habitat types, and the only two species common to both are Acantholepis capensis  and Camponotus maculatus. The degree of Hakea sericea infestation in the fynbos negatively affected ant species richness. Ant species richness in the Afromontane forest decreased from the drier to the wetter sites. The aggressive alien ant species, Iridomyrmex humilis, has not invaded natural areas to any great extent.
