The Chihuahuan Desert Network (CHDN) is one of 32 National Park Service Inventory and Monitoring networks nationwide conducting vital signs monitoring to assess the condition of park ecosystems and develop a stronger scientific basis for stewardship of natural resources across the National Park System.

The CHDN is comprised of seven national park units, located throughout the diverse landscapes of west Texas and southeast New Mexico. Each park contains a rich and varied array of natural and cultural resources. These parks and their partners are dedicated to understanding and preserving the region's unique resources through science and education. Visit the Network Parks pages to discover the particular resources found at each of these special places.
