Development of the acid water indicator community (AWIC) macroinvertebrate family and species level

The report comprises comments on two freshwater macroinvertebrate scoring systems for use in the biomonitoring of surface water acidification in England.



This report reviews one of the most commonly used macroinvertebrate acidification metrics (the University of Wales system) and presents two new scoring systems developed by CEH during this R&D contract ‘AWIC(fam)’ and ‘AWIC(sp)’ (the Acid Waters Indicator Community, family and Species scoring systems).
