Macrophytes provide habitats for fish and smaller animals, they bind sediments, protect banks and absorb nutrients. Macrophytes can indicate the impact of increased nutrients in rivers and are also influenced by other pressures such as channel engineering, water abstraction, flow impoundment or acidification. The types and amount of macrophytes present in a river can tell us how well that river is working.

This method has been designed primarily to detect the impact of toxic substances on the distribution of certain species of macroalgae (seaweeds belonging to the group known as 'wracks', and principally members of the genus 'Fucus'').  This method monitors the upstream limit of

Benthic invertebrate communities are good indicators of organic pollution and are also sensitive to toxic pollutants. They are ideally suited to biological monitoring as they are sedentary and either feed upon sediment dwelling animals or the sediment .
