Riverfly monitoring

The Angler’s Riverfly Monitoring Initiative (ARMI) is a national scheme, launched by the Riverfly Partnership in 2007 to enable anglers, interested groups and individuals to monitor and help to protect their local rivers. The scheme helps ensure rivers are monitored more widely and at greater frequency than is possible by the Environment Agency alone.

Pollution incidents can occur in rivers from many different sources, which can have disastrous effects on the river environment and wildlife which depends on it. Certain invertebrates are very sensitive to pollution and can be used as effective early indicators of pollution events. By monitoring certain invertebrate species, monitors can identify a pollution event and enable a rapid response before the problem becomes irreversible or wipes out entire watercourses.

Volunteers visit their allocated site on a monthly basis and carry out a 3 minute kick sample and record their findings. Find out where er are currently surveying as well as some suggested sites here.

The River Thame Conservation Trust is the riverfly hub for the River Thame Catchment and we run and organise all training courses. Our next FREE training day is on Saturday 21st July 9.30am – 5pm at Stadhampton Village Hall, Oxfordshire email Natalie@riverthame.org for further details or to sign up.
