The research broadly covers the revision and description of South African indigenous earthworms. The research activities aim at documenting and understanding the diversity and relationships of terrestrial earthworms in Southern Africa. A large part of earthworm research in South Africa was undertaken by Dr Plisko after she “retired”. She was appointed by the KZN Museum in 1988 on a ten year contract but is still very much active in earthworm research at age 90. Over the last three decades she has described more than 100 species over 40 publications. T Nxele is currently working on the revision of Kazimierzus and Dr Plisko is working on the revision of Microchaetus. Another project investigates earthworms in small and large scale farming under the no till practice.
