IIRC, there was one area in Scotland where beavers were released legally, and another area further south where they were illegally released. The authorities know about this second area but decided at the time not to do anything about it and just monitor the situation. Now, the beavers are causing a degree of havoc (chewing down trees and building dams that require removing), but it was recently decided to let the beavers stay, much to the dismay of local farmers and angling groups.
