The Four Canyon Preserve encompasses 4,000 acres along the Canadian River.



The Four Canyon Preserve encompasses 4,000 acres of mixed-grass prairie, rugged canyons and floodplain along the Canadian River in southern Ellis County. Scenic prairie ridges traverse the landscape, dissected by deep chinquapin oak-lined canyons draining into the river.

These prairies provide habitat for a number of rare grassland birds such as Cassin's sparrow and Swainson's hawk, and other species of concern including reptiles like the Texas horned lizard and most notably, the imperiled lesser prairie chicken. The cool, wooded canyons stand in contrast to the surrounding prairies and provide habitat for migratory birds like the red-bellied woodpecker and painted bunting.

The Canadian River provides habitat for the federally endangered least-tern, the threatened Arkansas River shiner and serves as a stopover point for migratory shorebirds like the sandhill crane.

Conservation Easements

Paul and Jackie Seeley of western Oklahoma conserved more than 1,700 acres of their family ranch through the USDA-NRCS Agricultural Conservation Easement Program in partnership with The Nature Conservancy. This easement will keep the property intact as a working ranch free from development in an effort to conserve remaining grasslands and protect wildlife that rely upon these unique ecosystems.

Water Returns to the Canadian River Like most rivers in the Great Plains, the Canadian River is seasonal. Back in 2013, Preserve Director Chris Hise caught a rare moment as an upstream rain event sends water downriver and releases air trapped in the sand.
