Protecting Native Species

The Lower Rio Grande Valley National Wildlife Refuge is actively involved in habitat protection and restoration through the control of invasive and exotic plant and wildlife species. All control efforts conducted on the refuge are designed to improve the conditions for native plant and wildlife populations.
