Between 1983 and 1988, tree cores and cookies were collected as part of a project conducted by the National Park Service to create final land cover maps for the GIS Thematic Mapper Landcover Mapping Project in the Wrangell-St. Elias National Park and Preserve. Vegetation type and percent cover, landform, drainage, slope, aspect, and soils data were collected for more than 1200 plots. Tree cookies or cores were collected for a sub-set of the ground truth sites (186 plots). The site locations were selected from aerial photographs that would provide representative vegetation types for mapping. Ground truth sites were assessed from the ground and aerially. Photos were taken for almost all of the plots.
