The saguaro, with its great size and characteristic shape—its arms stretching heavenward, its silhouette often resembling a human—has become the emblem of the Sonoran Desert of southwestern Arizona and northwestern Mexico. The largest and tallest cactus in the United States, it is both familiar and an object of fascination and curiosity. This book offers a complete natural history of this enduring and iconic desert plant. Gathering everything from the saguaro’s role in Sonoran Desert ecology to its adaptations to the desert climate and its sacred place in Indigenous culture, this book shares precolonial through current scientific findings. The saguaro is charismatic and readily accessible but also decidedly different from other desert flora. The essays in this book bear witness to our ongoing fascination with the great cactus and the plant’s unusual characteristics, covering the saguaro’s: history of discovery, place in the cactus family, ecology, anatomy and physiology, genetics, and ethnobotany. The Saguaro Cactus offers testimony to the cactus’s prominence as a symbol, the perceptions it inspires, its role in human society, and its importance in desert ecology.

Distinguished by its slender vertical branches, which resemble the tubes of a pipe organ, and growing to the imposing height of 15 to more than 30 feet, itÕs obvious how the organ pipe cactus got its name. In the United States, these spectacular and intriguing plants are found exclusively in a small area of the Sonoran Desert in the southwestern corner of Arizona. With a landscape marked by sharp, rocky slopes and daytime highs in the summer reaching 110 degrees Fahrenheit, the region is inhospitable for most ordinary life, whether plant or animal. But the organ pipe cactus is far from ordinary. Although it is the most common columnar cactus, it is so unusual in the United States that it is only one of three cacti to have a national preserve established to protect it. In this regard, it joins a select group of plantsÑincluding Joshua trees, redwoods, and sequoiasÑupon which that honor has been conferred. In this beautifully illustrated, large-format book, David Yetman provides an in-depth and comprehensive look at these intriguing and picturesque plants that most Americans will never have the opportunity to see. Chapters explore their ethnobotanical uses, their habitat, their distribution, and special conditions required for their germination, establishment, growth, and survival. Yetman also places the organ pipe in perspective as a member of a genus with at least twenty-three species, ranging from the prostrate Stenocereus eruca of Baja California to the 50-foot high giant S. chacalapensis of the coast of Oaxaca.

Medicine of God, Peyote: for some people, to use it is to hear colors and see sounds. For many Native Americans, it brings an ability to reach out of their physical lives, to communicate with the spirits, and to "become complete." What is it in peyote that causes such unusual effects? Can modern medical science learn anything from Native Americans' use of peyote in curing a wide variety of ailments? What is the Native American Church, and how do its members use peyote? Does anyone have the legal right to use drugs or controlled substances in religious ceremonies? Within this volume are answers to these and dozens of other questions surrounding the controversial and remarkable cactus. Greatly expanded and brought up-to-date from the 1980 edition, these pages describe peyote ceremonies and the users' experiences, and also cover the many scientific and legal aspects of using the plant.

In the darkness of the star-studded desert, bats and moths feed on the nectar of night-blooming cactus flowers. By day, birds and bees do the same, taking to blooms for their sweet sustenance. In return these special creatures pollinate the equally intriguing plants in an ecological circle of sustainability. The Sonoran Desert is the most biologically diverse desert in the world. Four species of columnar cacti, including the iconic saguaro and organ pipe, are among its most conspicuous plants. No Species Is an Island describes Theodore H. Fleming’s eleven-year study of the pollination biology of these species at a site he named Tortilla Flats in Sonora, Mexico, near Kino Bay. Now Fleming shares the surprising results of his intriguing work. Among the novel findings are one of the world’s rarest plant-breeding systems in a giant cactus; the ability of the organ pipe cactus to produce fruit with another species’ pollen; the highly specialized moth-cactus pollination system of the senita cactus; and the amazing lifestyle of the lesser long-nosed bat, the major nocturnal pollinator of three of these species. These discoveries serve as a primer on how to conduct ecological research, and they offer important conservation lessons for us all. Fleming highlights the preciousness of the ecological web of our planet—Tortilla Flats is a place where cacti and migratory bats and birds connect such far-flung habitats as Mexico’s tropical dry forest, the Sonoran Desert, and the temperate rain forests of southeastern Alaska. Fleming offers an insightful look at how field ecologists work and at the often big surprises that come from looking carefully at a natural world where no species stands alone.

The Sonoran Desert, a fragile ecosystem, is under ever-increasing pressure from a burgeoning human population. This ecological atlas of the region's plants, a greatly enlarged and full revised version of the original 1972 atlas, will be an invaluable resource for plant ecologists, botanists, geographers, and other scientists, and for all with a serious interest in living with and protecting a unique natural southwestern heritage. An encyclopedia as well as an atlas, this monumental work describes the taxonomy, geographic distribution, and ecology of 339 plants, most of them common and characteristic trees, shrubs, or succulants. Also included is valuable information on natural history and ethnobotanical, commercial, and horticultural uses of these plants. The entry for each species includes a range map, an elevational profile, and a narrative account. The authors also include an extensive bibliography, referring the reader to the latest research and numerous references of historical importance, with a glossary to aid the general reader. Sonoran Desert Plants is a monumental work, unlikely to be superseded in the next generation. As the region continues to attract more people, there will be an increasingly urgent need for basic knowledge of plant species as a guide for creative and sustainable habitation of the area. This book will stand as a landmark resource for many years to come.

"Describes the life cycle of the giant saguaro cactus, with an emphasis on its role as a home for other desert dwellers."--Title page verso.

A collection of writings on the ecology, evolution, and conservation of columnar cacti and their vertebrate mutualists, demonstrating that the survival of these cacti depends on animals who pollinate them and disperse their seeds.

A venerable saguaro cactus stands like a statue in the hot desert landscape, its armlike branches reaching fifty feet into the air. From a distance it appears to be completely still and solitary--but appearances can be deceptive. In fact, this giant tree of the desert is alive with activity. Its spiny trunk and branches are home to a surprising number of animals, and its flowers and fruit feed many desert dwellers. Gila woodpeckers and miniature elf owls make their homes inside the saguaro's trunk. Long-nosed bats and fluttering white doves drink the nectar from its showy white flowers. People also play a role in the saguaro's story: each year the Tohono O'odham Indians gather its sweet fruit in a centuries-old harvest ritual. In this first volume of Sierra Club Books' Tree Tales series, a simple, easy-to-read text and appealing drawings document the life cycle of this amazing cactus tree and the creatures it helps to support. Readers will come away with a better understanding of and a lasting respect for this accomodating giant of the desert.

"A Natural History of the Sonoran Desert provides the most complete collection of Sonoran Desert natural history information ever compiled and is a perfect introduction to this biologically rich desert of North America."--BOOK JACKET.
