Why are American mink a problem?
These animals, descendants from mink that escaped or were intentionally released from fur farms, are an ‘alien’ species, and don’t fit properly into Norfolk’s ecology. The American mink is a very undesirable resident in Norfolk and certainly not to be encouraged; in fact, due to the damage the animal can cause to native wildlife, especially species such as the water vole, the Norfolk Biodiversity Partnership is undertaking ongoing control programmes in mid-Norfolk and the Broads. Gamekeepers also undertake mink control in order to reduce predation of pheasants and partridge, all of which contributes to the control of this predator. Mink also hunt water birds, such as moorhen and ducks, and a noticeable decline in numbers of birds may indicate that mink are in the area. Mink are aggressive predators and will overkill prey. They can cause significant damage to housed or penned game birds or poultry by killing large numbers, far more than they can eat, and they may also damage fish stocks
