Despite recent heavy snowfall across much of northern Minnesota and deer populations being below target in some areas, residents are advised against feeding deer this winter, the Minnesota Department of Natural Resources said. Feeding deer can be well-intentioned, but can have detrimental effects and cause more harm to the animals than if they were left alone and allowed to draw on their natural survival instincts. Supplemental feeding creates problems in four major ways, behavior changes, animal concentration, human conflict, taxpayer expense. Rebuilding deer densities in areas that are below population targets is best done by managing the deer harvest and ensuring adequate habitat for healthy reproduction. Supplemental feeding is not a sustainable way to influence deer populations for the long-term. In most cases, allowing deer numbers to rebuild naturally is the best way to foster a strong and healthy animal population.
