In the Shadow of the Wall

From the Pacific Ocean to the Gulf of Mexico, the 2,000-mile U.S.-Mexico border passes through regions rich in biological diversity and communities engaged in conservation. For decades, U.S. and Mexican agencies, nonprofits, universities and ranchers, retirees and others have teamed up to restore rivers, streams, forests, grasslands and at-risk wildlife, to keep habitat linkages intact and to protect large natural areas.
