Description: Prior to this project high quality maps of aspen stands were lacking for the Lake Tahoe Basin. We generated a high resolution digitized aspen stand map using a variety of images from Google Earth and ArcMap. These included all available basemaps from both software programs as well as 2010 LIDAR canopy height and intensity data. To identify aspen sources we used data from the U.S. Forest Service and the Tahoe Basin Existing Vegetation Map as starting points. Available basemaps included both leaf-off and leaf-on dates. Leaf-off imagery was especially useful for identifying aspen trunks and downed wood and for performing mapping of individual conifer crowns within aspen stands. The 0.92 version of this product was produced by Hannah Williams and Tom Dilts at the University of Nevada Reno with input from Stephanie Coppetto of the US Forest Service and Scott Cecchi of the Tahoe Conservancy.
