Remembering This issue of the Arid Lands Newsletter is about remembering of the most basic sort. It's about remembering those;who came before and their ways of doing things. Without this base we cannot gain true knowledge. Ethnobiology embodies this fundamental kind of remembering: How did our ancestors use this plant or thatanimal? What were the benefits they derived from them? Maybe we haveforgotten too much. And so we present here some information that has been remembered in the hope that it will remind all of us of this basic truth: To have a balancedperspective we must integrate the wisdom of those who have gone before with the pursuits of those working onthe cutting edge. On a personal note, with this issue of the Arid Lands Newsletter I am bidding farewell and remembering,with fondness, my association with the Office of Arid Lands Studies and my time as editor of the Newsletter. I thankOALS and the Newsletter's founding editor, Patricia Paylore, for the opportunity to store up so many fine memories. -- Emily E.

Rea The Gila River Pima, or the Gileños, as they were known in Hispanic colonial times, are the northernmost group of Tepiman- speaking people; they inhabit lands from northern Jalisco in Mexico to the Phoenix region in Arizona. Their self -designation is Akimel O'odham, or River People. Their Piman relatives in the United States are various dialectical groups comprising the Tohono O'odham (Papago) in southwestern Arizona and the now extinct Sobaipuri in southeastern Arizona. This desert riparian people made a livelihood of gathering, farming, fishing, and hunting. Their agriculture was dependent on the biannual rise in the Gila flow: the first in the spring with the melting snow in the Gila headwaters, and the second with the advent of summer monsoonal storms from the south. Water at these times was diverted by brush weirs into an elaborate system of ditches that irrigated the nutrient -rich lower terraces of the river. It is not known for certain when the Gileños arrived at their riverine oases, but all versions of the Pima Creation Epic, as well as their oral history, tell of a Piman conquest of a puebloid people who were already living in these desert valleys. Archaeologists call the earlier people the Hohokam. The last evidence of the distinctive Hohokam culture, with its hundreds of miles of irrigation canals, characteristic ceramics, and complex of meso- American elements, disappears from the archaeological record by A.D. 1400 -1450. The new people, coming from somewhere in the Piman heartland, were culturally preadapted to use the flora and fauna at the northern fringes of the Sonoran Desert. And in spite of what appears to the outsider to be a rigorous environment, the Gila River Pima maintained a stable culture in their desert riparian ecosystem for at least four centuries. We know that it was stable and well within the local carrying capacity from numerous documentary accounts. Both Jesuit and Franciscan travelers in the Hispanic period marveled at the industrious and provident people they encountered on the Gila. Early in the Anglo period, the Gileños were able to respond to the needs of military and civilian Anglo immigrants, producing prodigious amounts of grain and other supplies far in excess of their own needs, for commerce. At least 95 biological species of plants entered the dietary of the Gila River Pima. Thirty of these are post- contact species (16 introduced annual crops and 14 fruit trees; this list excludes crops and products that were not named, such as olives, pepper, and okra, but that were occasional dietary items.) This leaves nearly 65 native plants known to have been eaten at some time during the River People's annual cycle. The Gila River Pima and their kinfolk, the Salt River Pima, are now best known not for their highly successful adaptation to desert living, but rather for having the highest known incidence of adult -onset diabetes of any ethnic group in the world. This condition was virtually unknown early in the century, but by World War II significant changes had occurred in Pima environment, culture, and eating habits. The ecological conditions that support desert rivers form a fabric that is easily damaged.
