SmartRivers Update – June 2019

May saw the initiation of another one of our SmartRivers pilot hubs. We are very happy to be adding two chalkstreams - the Avon and the Wylye - to the SmartRivers family, thanks to Wiltshire Fisheries Association.

Taking river guardianship into our own hands

For all rivers being added to SmartRivers, a professional scientist has to come and complete an initial benchmark, just for one year. We successfully collected the spring benchmark for the new Wylye and Avon sites, and will return to complete the benchmark in autumn. The benchmark is the backbone of any new SmartRivers hub, as it is a scientifically verified baseline to compare volunteer samples to.

Following collection of the benchmark, we had an exciting session teaching the WFA volunteers how to kick-sweep sample to the possible highest standard; from divvying up the habitats properly to using the correct net technique. Technique is crucial to ensure the data we obtain is as representative as possible and usable to drive change.

I took the opportunity to get up close and personal with one of my favourite nymphs - the flat-bodied mayfly. Their streamlined bodies have remained the same for millions of years, making them perfectly adapted to cling onto the riverbed under high flow conditions. Flat-bodied mayflies are great news for wild fish, as they are an important food source and indicate good water quality.

Later in the day we were off the river bank and inside giving WFA a lesson in cleaning and sorting their samples. SmartRivers is completely flexible, so you can get as hands on as you like. Whether you post your sample to an expert to identify, or ID yourself, there is an option for everyone.

Looking forward to autumn, which will see collection of the final benchmark sample and more training for WFA. This time focusing on species-level identification, using species from their own waters.
