This standard specifies equipment and procedures for the sampling of benthic macro-invertebrates by handnet in shallow waters (down to a dept of about 1,5 m) which are accessible either by wading or from a band or boat. The procedures are applicable to the sampling of all accessible aquathic habitats in rivers, streams, ponds, estuaries and lake shores. They provide qualitative data on the presence, absence, diversity and relative abundance of taxa depending on sampling effort and mesh size.
