Development of population control strategies for mink Mustela vison, using floating rafts as monitors and trap sites Original Research Article

We describe a raft designed to act both as a monitoring device and as a trap site for American mink, Mustela vison. The raft uses a wet tracking medium to record footprints. It was evaluated during summer in a chalk-stream river catchment in central southern England. The raft detected mink at significantly more sites (55%) than did either owners and managers relying on field observation and trapping (19%), or established biological survey techniques (33%).
