7) Including categories which are said to be fluctuating. The probable behaviour has been assumed true.
8) This species has declined to such an extent it is now considered to be only an occasional breeder. None of the other trend categories adequately reflect this status.
9) The population of wintering water birds is measured in the winter beginning in the year indicated, i.e. 2003 indicates populations measured from approximately November 2003 - March 2004
10) Includes grilse (salmon which have matured, or are about to mature, after one winter at sea).
11) Fixed engine fisheries operate in coastal areas. Net & coble fisheries are generally restricted to estuaries and the lower reaches of rivers. Rod & line fisheries cover recreational angling within river systems.
