Popis:	A study was undertaken between 29th January and 17th February 2004 to test the applicability of the South African Scoring System Version 5 (SASS5) scoring and calculation procedure in nutrient-enriched palustrine wetlands in the midlands of KwaZulu-Natal, South Africa. Four reference wetlands and three dairy-effluent impacted wetlands were sampled. Six macroinvertebrate samples were collected with a SASS net from each wetland. For each sample, the macroinvertebrates were identified and assigned a predetermined SASS5 tolerance score. Data for selected physico-chemical variables, macrohabitat condition, biotope suitability and organism detectability were collected to assist in interpretation of results. Thirty-eight taxa, identified to family level, were collected during sampling. Total SASS5 scores ranged from 15 to 82. Five of the wetlands had mean SASS5 scores of between 46 and 59. Five of the wetlands had an intra-wetland SASS5 score range of greater than 30. Average score per taxa (ASPT) values ranged ...
