The Akimel O'odham, or Pima Indians, of the northern Sonoran Desert continue to make their home along Arizona's Gila River despite the alarming degradation of their habitat that has occurred over the past century. The oldest living Pimas can recall a lush riparian ecosystem and still recite more than two hundred names for plants in their environment, but they are the last generation who grew up subsisting on cultivated native crops or wild-foraged plants. Ethnobiologist Amadeo M. Rea has written the first complete ethnobotany of the Gila River Pima and has done so from the perspective of the Pimas themselves. At the Desert's Green Edge weaves the Pima view of the plants found in their environment with memories of their own history and culture, creating a monumental testament to their traditions and way of life. Rea first discusses the Piman people, environment, and language, then proceeds to share their botanical knowledge in entries for 240 plants that systematically cover information on economic botany, folk taxonomy, and linguistics. The entries are organized according to Pima life-form categories such as plants growing in water, eaten greens, and planted fruit trees. All are anecdotal, conveying the author's long personal involvement with the Pimas, whether teaching in their schools or learning from them in conversations and interviews. At the Desert's Green Edge is an archive of otherwise unavailable plant lore that will become a benchmark for botanists and anthropologists. Enhanced by more than one hundred brush paintings of plants, it is written to be equally useful to nonspecialists so that the Pimas themselves can turn to it as a resource regarding their former lifeways. More than an encyclopedia of facts, it is the Pimas' own story, a witness to a changing way of life in the Sonoran Desert.
There is a common but often unspoken arrogance on the part of outside observers that folk science and traditional knowledge—the type developed by Native communities and tribal groups—is inferior to the “formal science” practiced by Westerners. In this lucidly written and humanistic account of the O’odham tribes of Arizona and Northwest Mexico, ethnobiologist Amadeo M. Rea exposes the limitations of this assumption by exploring the rich ornithology that these tribes have generated about the birds that are native to their region. He shows how these peoples’ observational knowledge provides insights into the behaviors, mating habits, migratory patterns, and distribution of local bird species, and he uncovers the various ways that this knowledge is incorporated into the communities’ traditions and esoteric belief systems. Drawing on more than four decades of field and textual research along with hundreds of interviews with tribe members, Rea identifies how birds are incorporated, both symbolically and practically, into Piman legends, songs, art, religion, and ceremonies. Through highly detailed descriptions and accounts loaded with Native voice, this book is the definitive study of folk ornithology. It also provides valuable data for scholars of linguistics and North American Native studies, and it makes a significant contribution to our understanding of how humans make sense of their world. It will be of interest to historians of science, anthropologists, and scholars of indigenous cultures and folk taxonomy.
Like many rivers of the arid Southwest, the Gila is for much of its length a dry bed except after seasonal rains. Yet a mere century ago it hosted a thriving biological community, and two centuries ago American Indians fished from its banks. It is no mystery how the desert swallowed up the Gila. Beaver trapping, overgrazing, and woodcutting first ruined natural watersheds, then damming confined the last drops of its surface flow. Historical sources and archaeological data inform us of the Gila's past, but its bird life further testifies to the changes. Amadeo Rea traces the decline of bird life on the Middle Gila in a book that addresses the broader issue of habitat deterioration. Bird lovers will find it a storehouse of data on avian migration patterns and on ornithological classification based on skeletal structure. Anthropologists can draw on its Piman ethnoclassification of birds, which links the Gila River tribe with various other Uto-Aztecan peoples of Mexico's west coast. But for all concerned with protecting our environment, Once a River offers evidence of change that might be apprehended elsewhere. It is a case history of a loss that perhaps need never have occurred.
