USGS NRP Tucson: Landscape Change in the Southwest

Changes in Riparian Vegetation in Arizona

Gila River near Clifton (09442000), October 4, 2000

Gila River near Clifton (09442000) October 4, 2000.
Dominic Oldershaw, Stake 358 Four floods larger than 15,000 ft3/s occured at this state after the 1980 photograph. Despite these floods, riparian vegetation increased to the point of completely obscuring the channel. Even the opening under the bridge is nearly blocked by the vegetation, which include cottonwoods, mesquite, coyote willows, Goodding willows, and brickellbush. Tamarisk is also present at this site but is a minor component of the riparian ecosystem
