34. Riverfly Monitoring on the Mimram

Theme: Status and monitoring


  • To monitor the status of the river and its species to gauge if its condition is improving

Project description

This project will establish a Riverfly Monitoring scheme on the Mimram.  Volunteers have been trained to monitor and survey pollution-sensitive river invertebrates on a monthly basis.

Riverflies are the 'bugs' found on the river bed, which are the basis of the wildlife food chain. The variety and volume are indicative of the health of the river.

The Riverfly Monitoring Initiative is a nationally recognised scheme which trains volunteers to become skilled surveyors, regularly providing useful data on the health of the river's invertebrate populations.  Not only does this allow the river's health to be monitored, but the data can also identify pollution incidents and has even been used by the Environment Agency to successfully prosecute polluters.
