This report presents national-scale trends in the macroinvertebrate communities of English rivers over 29 years (1991–2019).
Macroinvertebrates are monitored routinely as they are very good indicators of environmental quality. Understanding national invertebrate trends helps the Environment Agency to evaluate the effectiveness of management actions including changes to legislation, improved river quality standards and river restoration measures, against the impact of changing environmental pressures such agriculture, climate change, water abstraction and new chemicals.
