In 2021, Prosek traveled to the Texas Hill Country to understand the region's threatened prairie habitats, thus embarking on a project to explore the complex realities of contemporary American grasslands.
Prosek's art is influenced by his science-based, firsthand fieldwork, with his handwritten notes often lining the margins. The book features his richly detailed watercolors and silhouettes of animals, plants, and habitats that reinforce the importance of the prairies as their own complete ecosystems, as well as the boundaries that define them in the present day--from fencerows to distinguishing native prairies from ones with invasive grasses.

The same scientific curiosity, detailed artistry, and passionate attention Prosek brought to raising the awareness of species of trout are now acutely focused on the rich, intricate diversity of our native grasses.
