Pawnee is one of 20 grasslands throughout the western Great Plains that were established after the Dust Bowl in the 1930s. The goal was to initiate a grassland recovery effort after intense farming led to soil erosion that devastated the land and farming families. Since then, biodiversity here has expanded and now has many birds, mammals, reptiles, insects, amphibians, and fish. During the breeding season, Pawnee is home to the regionally endemic Mountain Plover and Thick-billed Longspur. Colorado’s state bird, the Lark Bunting, arrives in May in dense flocks — quite the spectacle. You may even catch a glimpse of a Golden Eagle snatching a jackrabbit for breakfast.
Don’t miss the Pawnee Buttes, the most notable geologic feature of the grasslands. Stop at the trailhead and hike among the badland-like formations; you’ll probably see Say’s Phoebe, Cliff Swallow, or Rock Wren.
I love living and working in the prairie. Wayne Fields, in a 1988 essay in American Heritage magazine, wrote this about the ecosystem: “The prairie, in all its expressions, is a massive, subtle place, with a long history of contradiction and misunderstanding. But it is worth the effort at comprehension. It is, after all, at the center of our national identity.”

Directions
Pawnee National Grassland, managed by the U.S. Forest Service, encompasses 193,060 acres in northeastern Colorado. From Denver, take I-25 north to Fort Collins and exit onto eastbound Hwy. 14. Go about 27 miles at which point access roads into the grassland will be on your left. To reach the trails at Pawnee Buttes, turn left onto CR 390.
