Find out more about Riverfly with this short film produced at Gledhow Valley Woods by the Aire Rivers Trust, funded by LNER. Groups are using Riverfly to measure the health of the River Aire and it's tributaries including our 4 newly trained Riverfly monitors at Roundhay. Jane, Hilary, Rosa and Jodie are testing at Ram Beck, Foxwood Beck and Great Heads Beck each month. You can see our findings so far and the results across the Aire https://riverflydata.org/
