Phytobenthos are good indicators of nutrient enrichment and other pressures, and can be used to assess river water quality. Diatoms are the main plant groups that we use because their silica shells are easy to identify under the microscope.

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.
