Otero Mesa, located in rural southeastern New Mexico near the Texas border, is the largest public expanse of undisturbed Chihuahua Desert grassland left in the state. This stunning area is widely considered to be among the most biologically rich and diverse desert eco-regions in the world. It's home to hundreds of species of plants, mammals, reptiles, birds and insects in addition to endangered species such as the Northern Aplomado falcon.

Underlying Otero Mesa is the largest untapped freshwater aquifer in New Mexico, the Salt Basin Aquifer. Currently, ninety percent of New Mexico depends on groundwater for its water supply. A study conducted by the U.S. Geological Survey (USGS) confirmed that there is a significant volume of fresh water in the Salt Basin Aquifer, perhaps enough water for 1 million people for 40 years. Therefore, the Salt Basin Aquifer contains much of the region's future water supply.

From a recreational standpoint, New Mexico's Otero Mesa provides phenomenal opportunities to people seeking unique experiences. It includes the state's largest roadless areas and several small but prominent mountains containing numerous petroglyphs. Wildlife viewing, hiking, rock climbing, photography, hunting, camping and horseback riding are just a few of the many ways people enjoy this majestic landscape.

The National Wildlife Federation and its state affiliate, the New Mexico Wildlife Federation, continue to lead conservation efforts with the Coalition for Otero Mesa while working with the New Mexico delegation and other Members of Congress to protect the water and other outstanding natural resources of Otero Mesa.
