San Pedro River riparian ecological condition map

Streamside riparian vegetation in the Southwest provides some of the richest wildlife habitat and most popular recreational areas, but it thrives only in narrow strips along streams with permanent surface water or shallow groundwater. Small reductions in groundwater levels can stress riparian trees, and large reductions lead to loss of cottonwood and willow trees and loss of habitat values. This mapping of riparian condition gives both a direct measure of habitat value and an indirect measure of groundwater levels.
