San Pedro River riparian ecological condition

Riparian-aquatic
San Pedro River
Abstract

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.

This map is one of four downloadable San Pedro River Watershed Maps.

Landscape-scale forest restoration decreases vulnerability to drought mortality under climate change in southwest USA ponderosa forest
Drought is projected to increase tree mortality in many western US forests due to climate change and could result in large-scale tree die-offs, altering forest composition and ecosystem services. Tree mortality has also been found to be higher in forests with greater tree density. Southwestern US fo[…]

Tree mortality response to drought-density interactions suggests opportunities to enhance drought resistance
A future of hotter temperatures and less precipitation under climate change could increase tree mortality under drought conditions in dry forests across the western U.S., causing large-scale tree die offs.  Restoration projects that reduce densities of overgrown forests can result in lower competit[…]
