This dataset is a bureau-level statistical table of stand stock volume stratified by age group and constituent tree species, originating from the 1997 second-class forest inventory conducted by the Forest Management Bureau of Antu County, Yanbian Korean Autonomous Prefecture, Jilin Province. Collected in 1997, the dataset compiles the total stock volume across various forest types and three age groups (young, mature, over-mature), as well as the stock volume of each constituent tree species including Korean pine, spruce, Mongolian pine, Dahurian larch, Khingan fir, Manchurian ash, Manchurian walnut, Amur corktree, linden, Mongolian oak, elm, Acer maple, Betula costata, white birch, poplar, and miscellaneous hardwoods. As a core source for forest resource statistics, the second-class forest inventory data represents a critically important statistical material in forestry production.
