Dr Mike Sturt and Dr Charlotte Hall took part in a really useful workshop on Redox and dissolved oxygen measurements in interstitial river bed sites and equipment maintenance from Juergen Geist & Kathi Stoeckl, hosted by the Freshwater Biological Association, Windermere. This information and great practical experience will be applied to our monitoring work and will provide valuable data and insight into the habitats preferred by the fresh water mussel populations.
