U.S. Fish and Wildlife Service law enforcement officers have a wide variety of duties and responsibilities. Officers help visitors understand and obey wildlife protection law. They also work to ensure that visitors have safe experiences on national wildlife refuges. Federal wildlife officers work closely with state and local government offices to enforce federal, state, and refuge hunting regulations that protect migratory birds and other game species from illegal take and preserve legitimate hunting opportunities. Some other duties include patrolling refuges for violations, maintaining relationships with neighboring landowners, protecting refuge boundaries and participating in public events related to refuge issues.
Law enforcement issues should be referred to the refuge’s federal wildlife officer or refuge manager.
