Austropotamobius pallipes, the only native crayfish species in the UK, has declined over the past 30 years mainly due to the introduction and subsequent spread of Pacifastacus leniusculus, a North American species, which carries crayfish plague. This paper examines the reasons for the rapid decline of native crayfish and summarises a recent scoping study to determine how the remaining A. pallipes populations can be safeguarded.
