Leopold et al. (1947) conducted a survey of over-populated deer ranges in the United States and described approximately 100 herds that were over-populated. We identified deer experts in each state and asked a series of questions related to changes in their herds since 1947. Deer populations and their distribution have increased since 1947 and deer are in every state. Deer have effectively been controlled with hunting and habitat manipulation in many areas. Herds that are still overpopulated are not hunted, have an inadequate doe harvest, or inadequate harvest.
