The Riverfly Partnership

The Riverfly Partnership is a dynamic network of organisations, representing anglers, conservationists, entomologists, scientists, water course managers and relevant authorities, working together to: - protect the water quality of our rivers; - further the understanding of riverfly populations; - and actively conserve riverfly habitats. The Riverfly Partnership is hosted by the Freshwater Biological Association.

A complementary suite of freshwater invertebrate based monitoring tools for citizen scientists

A group of people stand in a river and crowd around their nets as they check their samples, a grassy bank can be ssen in the backgroundAs the population continues to expand, and our dependence on the environment increases, it is more important than ever that we keep a close eye on the health of our water ecosystems. Thankfully, there are a wide variety of citizen science schemes available that enable people of all ages and knowledge levels to engage with and monitor the condition of their rivers.

Riverfly monitoring is a brilliant way for volunteers to carry out river health checks. Freshwater invertebrates spend the majority of their lifecycles as larvae living underwater, sometimes for years! The abundance and diversity of the invertebrate community present in a river is highly linked with the quality and quantity of the water surrounding them. This relationship means that invertebrates are excellent indicators of water quality which, when monitored, provide data that can be used in diagnostic testing. Similar to a blood test, by looking at what’s there and what isn’t, we can derive a wealth of information about their condition.

There are many Riverfly monitoring schemes around, so it can be tricky to understand why so many different schemes are necessary. To address this, together with our colleagues at Salmon & Trout Conservation, we have built a helpful one page document that explains how ARMI, the Extended Riverfly scheme (due to be launched nationally along the Urban Riverfly scheme at the 5th Riverfly Partnership conference at the Natural History Museum, London on 20 March 2020), Riverfly Plus and SmartRivers all fit together. They do provide different types of information for slightly different purposes, but are all hugely important in our efforts to conserve and protect riuvers and streams.

So, whether you choose to volunteer for one scheme, more than one or all of them, please know that your contribution is incredibly valued and from all of us at the Riverfly Partnership and Salmon & Trout Conservation, thank you.

Beautiful Identification Sheet; the True Mayfly or Greendrake by Lincolnshire Chalk Streams Project

Wonderful volunteers from the Lincolnshire Chalk Streams Project have been collaborating with the EA to create a set of beautiful identification sheets. A pair of true mayfly larvae, or greendrake are shown, The triangular shape of the markings on their bodies are pointed out with red labels

Click here for a PDF of their True Mayfly or 'Greendrake' identification sheet 

Rachel Graham, assisted initially by Jade Oliver has worked extensively on the identification sheets. The photographs have been supplied by John Boulton. The project is managed by Lincolnshire Chalk Streams Monitoring Officer Will Bartle, and the EA contacts who provided ecological expertise are Richard Chadd and Chris Extence. 

The Lincolnshire Chalk Streams Project is a collaboration between Anglian Water, Wild Trout Trust, Natural England, Lincolshire County Council, Lincolnshire Wildlife Trust, The Environment Agency, and their host; Lincolnshire Wolds Countryside Service. 

They have done outstanding work to improve and restore chalkstreams in Lincolnshire, as well as raising awareness and knowledge of chalk streams and their importance. In 2012 they were awarded the prestigious Bowland Award from the National Association for Areas of Outstanding national Beauty. This award acknowledges outstanding projects that achieve landscape scale conservation through partnership working.

We will be uploading more of their sheets in the future. We hope that you enjoy their wonderful work.
