​Nematology Unit of the ARC-PPRI Biosytematics Division founded the South African Plant-Parasitic Nematode Survey (SAPPNS) in 1987. The aim is to make a comprehensive assessment of the nematode biodiversity resources of South Africa.

The main objectives of the SAPPNS are:

  • to make an inventory of all the plant-parasitic nematodes of South Africa

  • to study the biogeography of these plant-parasitic nematodes

  • to establish an electronic database of these plant-parasitic nematodes at the NCN and

  • to compile distribution maps of each economically important plant-parasitic nematode species.
