England has the largest number of chalk rivers of any European country, with a cumulative length of nearly four thousand kilometres. The cultural and economic value of such rivers is also high; water abstraction, irrigation, fisheries management, energy provision and navigation are just some of the demands placed upon chalk rivers both historically and today. Consequently, the conservation of chalk rivers is a key concern for land managers, with ten chalk river Sites of Special Scientific Interest (SSSI’s) and four candidate Special Areas of Conservation (cSAC’s) across England.
