This book is about the author’s personal laboratory for ecological studies, which he created by replacing the Bermuda grass in his suburban Arizona lawn with gravel, cacti, and fairy dusters. He seeded his property with flowers to entice certain insects and even added a few cowpies to attract termites. His observations of life in his own front yard provided him with the fieldnotes for this unusual book .

The book draws readers into the strange and fascinating world of plants and animals native to Arizona’s Sonoran Desert. As Alcock studies the plants in his yard, he shares thoughts on planting, weeding, and pruning that any gardener will appreciate. And when commenting on the mating rituals of spiders and beetles or marveling at the camouflage of grasshoppers and caterpillars, he uses humor and insight to detail the lives of the insects that live in his patch of desert. Celebrating the virtues of even aphids and mosquitoes, Alcock draws the reader into the intricacies of desert life to reveal the complex interactions found in this unique ecosystem .

About the Region

Fall Symposium 2025 Logo - Teach for the Future

Salado, the location of our Fall 2025 Symposium, lies at the intersection of two ecoregions: the Edwards Plateau (Limestone Cut Plain) and Blackland Prairie (Northern Blackland Prairie).

The Edwards Plateau area is also called the Hill Country; however, this general term covers a much larger area extending farther north. Spring-fed creeks are found throughout the region; deep limestone canyons, rivers, and lakes (reservoirs) are common. Ashe juniper is perhaps the most common woody species found throughout the region. Additional woody species include various species of oak, with live oak (Quercus fusiformis) being the most common. Sycamores (Platanus occidentalis) and bald cypress (Taxodium distichum) border waterways. This area is well known for its spring wildflower displays, though they may be viewed in spring, late summer, and fall, as well. According to Texas Parks and Wildlife, average annual rainfall in the Edwards Plateau ranges from 15 to 34 inches.

The Blackland Prairie extends from the Red River south to San Antonio, bordered on the west by the Edwards Plateau and the Cross Timbers, and on the east by the Post Oak Savannah. Annual rainfall averages 30 to 40 inches, with higher averages to the east. This region is dominated by prairie species. The most common grass species include little bluestem (Schizachyrium scoparium) and Indian grass (Sorghastrum nutans) in the uplands and switchgrass (Panicum virgatum) in the riparian areas and drainages. Common herbaceous flowering plants include salvias, penstemons, and silphiums. This area has suffered greatly from overgrazing and agricultural use. Few intact areas remain, though many of the plants can be found along county roadsides throughout the region.

Our fall Symposium host chapter, the Tonkawa Chapter, includes both of these ecoregions.
