Many wildlife biologists support the use of regulated trapping for the sustained harvest of some species of furbearers. Studies have repeatedly shown that trapping can be an effective method of managing or studying furbearers, controlling damage caused by furbearers, and at times reducing the spread of harmful diseases. These studies have shown that regulated trapping is a safe, efficient, and practical means of capturing individual animals without impairing the survival of furbearer populations or damaging the environment. Wildlife biologists also support regulatory and educational programs, research to evaluate trap performance and the implementation of improvements in trapping technology in order to improve animal welfare.
