Abstract:

This data publication contains tree observations (n = 1,361) made within the Nez Perce National Forest near Elk City, Idaho, in August and September 2018. Trees were measured within 56 circular fixed-radius plots, which had plot radii of 11.3 meters and were 400 square meters in area. Plots were located in areas of insect-caused tree mortality, as indicated by USDA Insect and Disease Detection Survey polygons, to sample a variety of tree mortality agents and severities. These observations were then used to train and evaluate the classification of satellite imagery to map tree mortality. Tabular data include tree species, health, diameter at breast height, crown class, insect mortality agent, beetle attack status, years since death, and location information.
