Resource Management


Refuge managers and wildlife biologists utilize various tools to manage the Lower Rio Grande Valley National Wildlife Refuge for the benefit of wildlife and you. 

  • Creating a Wildlife Corridor

    The refuge is currently comprised of more than 115 separate tracts of land, most of which follow the last 275 river miles of the Rio Grande. The management strategy is to protect habitat and ultimately connect those tracts by directly purchasing land from willing sellers, through conservation easements, or by working with private landowners interested in managing their property for the benefit of wildlife.

  • Restoring Habitat

    Staff and volunteers grow native trees and plants on an on-site nursery or with the help of local growers.  Between the refuge staff and local growers, approximately 225,000 plants representing up to 60 species are grown every year.  These native trees and shrubs are then planted on refuge lands with the help of a cooperative farming program.

  • Wetlands Management

    The refuge has an active management approach to improving and restoring wetlands for the benefit of wildlife. To mimic the flooding of the Rio Grande, refuge staff use pumps and other infrastructure to deliver water to the 'resacas' (oxbow lakes), crucial wetlands that provide habitat for wildlife that nest, rest, feed and raise their young in these wetlands.

  • Protecting Native Species

    Protecting native wildlife and plant species are a top management priority for the Lower Rio Grande Valley National Wildlife Refuge. The refuge strives to restore and enhance habitat for the benefit of all native species, endangered or otherwise.  To do this, efforts focus on managing exotic and invasive species that out-compete and displace native species.
