Restoring Fly Populations

Wednesday, 8th August 2018

Well known entymologist Dr Cyril Bennett has written up a number of methods for attempting to restore fly populations in rivers.
As Cyril notes in his recent interesting paper, these methods are aimed not at trying to boost existing fly numbers but rather for situations where pollution has impacted local populations and recolonisation from upstream is limited. Cyril also makes the really important point that such methods are only applicable where the issues that caused any perceived fly declines have been tackled.
