Evaluation of UK conservation concerns.
Conservation managers (n = 132), public respondents (n = 186) and anglers (n = 103) were asked to select one species from a range, (a) red squirrel, native crayfish or coarse fish, (b) red squirrel, native crayfish or salmon, for which a disease to, would cause the most ecological concern.
