One of the largest opportunities for grassland conservation in the U.S.

The Southern High Plains of Colorado, Kansas, New Mexico, Oklahoma and Texas are home to pronghorn, grassland birds and more iconic wildlife. TNC is working with partners to conserve a network of land and water across state boundaries that boosts climate resilience, preserves biodiversity and supports sustainable agriculture. Together, we’re increasing the pace and scale of grassland protection.
