Book Description
Yet Matt Ridley does more than describe how things are getting better. He explains why. Prosperity comes from everybody working for everybody else. The habit of exchange and specialization---which started more than 100,000 years ago---has created a collective brain that sets human living standards on a rising trend. The mutual dependence, trust, and sharing that result are causes for hope, not despair. --

Book Description
In comparison to the vegetation of most of temperate North America, the southwestern deserts contain highly unusual plants adapted in form and function to the extremes of arid environments. So striking are some of these plants that three national monuments-Saguaro, Organ Pipe Cactus, and Joshua Tree-are named for them. In each case, it is a single species that gives unique character to the desert landscape within the monument. Of all the remarkable plants of the desert Southwest, the giant cactus, or saguaro (Carnegiea gigantea), stands out in the minds of many Americans as an icon representing the novelty and grandeur of the desert realm. Saguaro National Monument (SAGU) was established in 1933 on the east side of Tucson, Arizona, to protect what was then one of the most awe-inspiring stands of saguaros to be found anywhere in the Sonoran Desert. Yet today, little more than a half century later, the giant, manybranched saguaros have all but disappeared from the original "cactus forest" of the 1930s (Fig. 1). Since the primary mission of National Park Service (NPS) at SAGU is to protect the distinctive cactus species for which the monument was named, the saguaro has understandably been the subject of considerable concern and research at SAGU since the late 1930s. The purpose of this report is to (1) trace the development of various research and monitoring efforts involving the saguaro at SAGU, (2) evaluate the rationale for these investigations, and (3) examine some of the impacts of these research efforts on management decisions and public perceptions regarding the ecological status of this extraordinary plant.

Book Description
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.
