Britain's Biodiversity Action Plan riverflies - dossiers and management sheets

There are 8 riverfly species with government conservation status under the Biodiversity Action Plan (BAP). The Riverfly Partnership, Riverfly Recording Schemes and Buglife have been working to produce dossiers and management advice sheets for each of these species. These are a valuable resource for anyone seeking further information on the BAP riverflies, and are essential tools to inform conservation efforts for these species. The dossiers and management sheets were produced with funding from Natural England Countdown 2010. They can be downloaded from the Buglife website.

National Geographic - Mayflies in a Changing Climate

The effects of climate change on British mayflies are discussed in a recent Water Crisis News article by James Owen. Water Crisis News is a special National Geographic News series on global water issues.

The article also features contributions from Steve Ormerod of Cardiff University and Craig Macadam of Buglife, highlighting the changes taking place in British mayfly populations and the ongoing research into the ecological impacts of climate change in British rivers. All three contributors are partners in The Riverfly Partnership.
