In the United States, hunting is both a wildlife management tool and an outdoor tradition. The North American Model of Wildlife Conservation describes the way we manage access to wildlife to ensure healthy wildlife populations into the future.
By respecting seasons and limits, hunters help ensure that wildlife populations are sustainable. Funds from licenses, federal duck stamps, and excise taxes on hunting equipment and ammunition help purchase and set aside millions of acres for wildlife.
With a few exceptions that vary by state, everyone who hunts must have the required state license(s). If you're hunting on a national wildlife refuge, some also require their own permits and/or user fees. In additional to hunting programs, state agencies have jurisdiction over: animal control and management of non-endangered wildlife species; management of State parks, forests and recreation areas; and game warden information.
