Coypu occurrence records from 1980 to 2018 in Europe. The decade-wise accumulation of records is depicted on the left side, with records of the respective decade in black and records of previous decades shown in grey. On the summary map (right side), records in Great Britain are displayed in red, as the coypu is officially eradicated (see Gosling and Baker 1989). Note, that for optimised illustration purposes, 10-km buffered centroids of occurrence records are shown.
