Protocols for sampling macroinvertebrates in wadeable streams

Publication date:  November 2001
Publication reference number:  SMF 5103

This protocol identifies and describes standardised protocols for use by agencies throughout New Zealand for macroinvertebrate biomonitoring. Aquatic macroinvertebrates are universally accepted indicators of pollution in fresh waters, but they are sampled and used in widely differing ways nationally. The use of standard methods will enable more defensible and consistent biomonitoring regionally and nationally, increase consultation between water agencies, facilitate national state of the environment reporting,and is an important pre-cursor to developing consistent national databases.
