River Invertebrate Identification and Monitoring (RIIM)

River Invertebrate Identification and Monitoring (RIIM) facilitates water quality monitoring by identifying freshwater invertebrates to species level and enables trained volunteers to carry out highly specialised surveys of the invertebrates in their rivers. Data recorded during such surveys can highlight any shortfalls in river invertebrate abundance and point the way to a solution by identifying probable causes. RIIM has been developed and is supported by Salisbury and District Angling Association, Aquascience Consultancy Limited, Salmon & Trout Conservation UK and the John Spedan Lewis Trust for the Advancement of the Natural Sciences.
