A collection of essays on the ecology, biodiversity, and restoration of the Texas Hill Country.

For most of five decades, evolutionary biologist David Hillis has studied the biodiversity of the Texas Hill Country. Since the 1990s, he has worked to restore the natural beauty and diversity of his Mason County ranch, the Double Helix. In his excursions around his ranch and across the Edwards Plateau, Hillis came to realize how little most people know about the plants and animals around them or their importance to our everyday lives. He began thinking about how natural history is connected to our enjoyment of life, especially in a place as beautiful and beloved as the Hill Country, which, not coincidentally, happens to be one of the most biodiverse parts of Texas.

Featuring short nontechnical essays accompanied by vivid color photos, Armadillos to Ziziphus is a charming and casual introduction to the environment of the region. Whether walking the pasture with his Longhorn cattle, explaining the ecological significance of microscopic organisms in springtime mud puddles, or marveling at the local Ziziphus (aka Lotebush, a spiny shrub), Hillis guides first-time visitors and long-term residents alike in an appreciation for the Hill Country’s natural beauty and diversity.

Hillis brings encyclopedic scientific knowledge to the task of explaining the Hill Country’s 'natural wealth.' He doesn’t allow scientific jargon or Latin taxonomy to muddy his prose, however. Using plain, understandable language, he paints accessible portraits of the land he’s spent a lifetime walking and exploring...He dissects the region with both practiced ease and great authority, tapping his wisdom as a scientist, as a scholar and as a lover of nature. Reading the book feels much like perusing a personal journal that captures a lifetime of experiences...Armadillos to Ziziphus is one of those books that can be read in one sitting or used as a go-to compendium, whereby the reader looks up something sparked by a curious moment.

I go back to these elegant, accessible essays again and again. There's just something so appealing about an accomplished scientist such as David M. Hillis, who can speak and write in way that's open to just about everybody, including the neighbors of his ranch in Mason County. Chief of the Biodiversity Center at the University of Texas, he explains the interplay of the elements in transparent prose in Armadillos to Ziziphus: A Naturalist in the Texas Hill Country (University of Texas Press). If I owned a Hill Country cabin, this book would be waiting to delight and inform every guest.
