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.

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.

Salado is an enigma of the past. One of the most spectacular cultures of the ancient Southwest, its brilliant polychrome pottery has been subjected to varied interpretations, from religious cult to artistic horizon. Stephen Lekson now uses data from two Salado sites—a large pueblo and a small farmstead—to clarify long-standing misconceptions about this culture. By combining analysis of the large whole-vessel collection at Dutch Ruin with the scientific excavation of Villareal II, a picture of Salado emerges that enables Lekson to evaluate previous competing theories and propose that Salado represents a major fourteenth-century migration of Pueblo peoples into the Chihuahuan deserts. Lekson demonstrates that late, short-lived Salado farmsteads—difficult to identify archaeologically in areas with larger Mimbres concentrations—coexisted with larger Salado towns, and he argues that Salado in the Upper Gila region appears as a substantial in-migration of Mogollon Uplands populations into what was a vacant river valley. Throughout the fourteenth century, Salado communities in the Upper Gila were integrated into the larger Salado horizon and were closely connected to Casas Grandes, as indicated by the export of serpentine to the city of Paquimé and the occurrence of Casas Grandes pottery at Upper Gila Salado sites. The book includes illustrations of 71 vessels from Dutch Ruin plus a full-color frontispiece. Through analysis of these two sites, Lekson has taken a large step toward clearing up the mystery of Salado. His work will be welcomed by all who study the movements of peoples in the prehispanic Southwest.
