Gathering its waters from the plains of Colorado, Kansas, and Nebraska, the Kaw is truly America's prairie river; the only one to arise entirely on the Great Plains and traverse all three major grasslands—shortgrass, mixed-grass, and tallgrass prairies. James Locklear's In the Country of the Kaw is a joyous exploration of the realm of the Kaw River, which stretches from the High Plains of Colorado to the Kansas City metropolitan area.

The book's first section profiles geology, landforms, and the region's woodlands and grasslands. The second explores the rich biological diversity associated with the land and its inhabitants' remarkable adaptations to the environment and each other. The final section is a collection of stories of human interaction with the landscape, how nature has shaped culture and culture nature. Locklear finds "astonishments" at every turn.

In the Country of the Kaw is also a call to seek the flourishing of the natural and human communities of the region. Locklear describes staggering, human-wrought environmental degradations, but also finds great hope in the resilience of Nature and the inspiring work of conservation, preservation, restoration, and renewal being accomplished by individuals and organizations throughout the region. Locklear's relationship with the country of the Kaw stretches from his childhood in Kansas City in the 1960s to his current professional life as a botanist working in the Great Plains. A half century of rambling and rooting around in this region has given him a deep awe and affection for its uniqueness and goodness, which he conveys to the reader on every page.
