Law Enforcement


The U.S. Fish and Wildlife Service maintains a strong law enforcement presence on the Lower Rio Grande Valley National Wildlife Refuge.

Federal wildlife law enforcement officers patrol the refuge to ensure the safety of the public and the protection of natural resources. They address many illegal activities, including taking of endangered species, dumping of trash, illegal use of all terrain vehicles, trespassing and more. They work very closely with U.S. Border Patrol agents who regularly patrol the refuge and assist as needed.

To report a violation on refuge lands during the daytime (7:30am to 5pm), please call: (956)784-7520 or (956)784-7608

To report a violation after hours, please call: (956)874-4664 or (956)330-5007
