    Description

    The Pinaleño Mountains in southeastern Arizona represent a Madrean sky island ecosystem that contains the southernmost expanse of spruce-­r forest type in North America. This ecosystem is also the last remaining habitat for the Mt. Graham red squirrel (Tamiasciurus hudsonicus grahamenis), a federally listed endangered species. Due to a general shift in species composition and forest structure of spruce-­r type forests across the Southwest, the ecosystem is being threatened by large high-severity ­res, insect infestation, and a general loss of biodiversity. These risk factors have led the Coronado National Forest to begin a forest restoration effort using LiDAR (light detection and ranging) as a tool for identifying habitat and cataloging forest inventory variables at a landscape level. LiDAR was identi­ed as an ef­cient tool for ­lling the data collection needs because ­eld data collection is restricted due to rugged terrain and safety concerns.
