Book Description
Excerpt from Natural Vegetation of Casa Grande Ruins National Monument, Arizona The monument was established in 1918. The land was never plowed during historic times, although it is currently surrounded by groundwater and river-irrigated agriculture. The boundary was fenced to protect it from livestock grazing in 1934. Decline of the water table caused the native mesquite trees to die during the 19405 (judd It is conceivable that the effects of grazing, water table decline, and possibly pesticide drift from aerial spraying of nearby cotton fields have reduced or eliminated other floral elements as well.

Book Description
As biological diversity continues to shrink at an alarming rate, the loss of plant species poses a threat seemingly less visible than the loss of animals but in many ways more critical. In this book, one of America's leading ethnobotanists warns about our loss of natural vegetation and plant diversity while providing insights into traditional Native agricultural practices in the Americas. Gary Paul Nabhan here reveals the rich diversity of plants found in tropical forests and their contribution to modern crops, then tells how this diversity is being lost to agriculture and lumbering. He then relates "local parables" of Native American agriculture—from wild rice in the Great Lakes region to wild gourds in Florida—that convey the urgency of this situation and demonstrate the need for saving the seeds of endangered plants. Nabhan stresses the need for maintaining a wide gene pool, not only for the survival of these species but also for the preservation of genetic strains that can help scientists breed more resilient varieties of other plants. Enduring Seeds is a book that no one concerned with our environment can afford to ignore. It clearly shows us that, as agribusiness increasingly limits the food on our table, a richer harvest can be had by preserving ancient ways. This edition features a new foreword by Miguel Altieri, one of today's leading spokesmen for sustainable agriculture and the preservation of indigenous farming methods.

Book Description
Juan Bautista de Anza led the Spanish colonizing expedition in 1775-76 that opened a trail from Arizona to California and established a presidio at San Francisco Bay. Franciscan missionary Fray Pedro Font accompanied Anza. As chaplain and geographer, Font kept a detailed daily record of the expedition's progress that today is considered one of the fundamental documents of exploration in the American Southwest. This new edition includes Font's recently discovered field journal--the actual notes he wrote on the trail. Previously published only in Spanish, this journal contains many details and perspectives not found in the two "official" versions that Font prepared after the expedition. It supplants the 1930 edition prepared by Herbert Eugene Bolton, which was based solely on Font's "official" texts. With Anza to California, 1775-1776 interweaves and correlates for the first time all existing texts of Font's journal and incorporates the latest research on this pathbreaking expedition. Editor Alan K. Brown has rendered a more accurate translation, allowing us to relive the journey through Font's eyes as the friar presents a panorama of history, geography, and ecology. Font also describes the interaction between Hispanic settlers and Native peoples--revealing Spanish relations with the Quechans on the Colorado River and the Kumeyaay uprising in San Diego. Featuring maps and relief profiles drawn by Font, along with new maps prepared by Brown, this edition includes an extensive introduction and copious explanatory notes. It is the most complete account of the Anza expedition and a foundational primary source in California and Southwest history.
