This desktop study aims to provide an informative review of the current knowledge and available habitat for exposed riverine sediment (ERS) invertebrates in Lancashire and Cheshire, with some recommendations for further study. The objectives of the report are to 1) collate the existing data on the ERS invertebrate communities in Lancashire and Cheshire, and 2) identify gaps in knowledge and flag up rivers and locations which would potentially reward further survey.
