The Historic changes in the upper River Ehen project (ref: S/0016/W) is a contract between United Utilities and the Freshwater Biological Association (FBA). It commenced in July 2014 with the overall objective “to provide evaluation of the historical changes that have been made to the catchment that will be of benefit to the management of the River Ehen, Ennerdale Water and the pearl mussel population in future.” The River Ehen holds the largest population of Freshwater Mussel (FWPM) in England, estimated at 550,000 individuals (Killeen & Moorkens, 2013) and is one of the priority river catchments in the country. Due to the presence of these mussels the River Ehen has been designated as Site of Special Scientific Interest (SSSI) since 1997 and as Special Area of Conservation (SAC) since 2005. During the last three decades many scientific projects have been undertaken in the area with the main purpose of understanding, protecting and restoring the mussel population and its habitat. Nevertheless the knowledge about what happened in the catchment prior to the 1950’s has been overlooked or forgotten. This project provides information that has not been analysed in terms of changes within the catchment over the last two-hundred years.
