Volunteer with West Cumbria Rivers Trust

Riverfly are an important part of the river ecosystem providing food for all the larger organisms that live in and around the rivers. Riverfly encompass all small invertebrates that live on and in the sediment at the bottom of the river, from snails to mayflies to worms.  Riverfly can be used to detect pollution events and show how a river is changing through time, without the need of catching the larger organisms such as fish and birds, or expensive laboratory testing. Our Riverfly volunteers attend volunteer training events before heading out independantly to survey their own river patch.
