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.
Once A River documents the changes in distribution of central Arizona bird life over the past four centuries. . . . It is a creative detailed look at Arizona avifauna and, more uniquely, an indictment against European-era land ethics.
—Western American Literature
A significant contribution to our understanding of man's thoughtlessness regarding natural events.
This is probably the best documented study to date on the results of human misuse of a desert riverine system. . . . Highly recommended.
This unique and beautifully illustrated book contains lessons of value to all of us, no matter where we live.
—The Canadian Field-Naturalist
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.
