A Lodgepole Pine Commercial Thinning Trial in Kananaskis, Alberta
註釋In 1941, the Canadian Forestry Service established a commercial thinning trial in a stand dominated by 77-year-old lodgepole pine near Kananaskis, Alberta. Sample plots established in 1949 were re-measured in 1999, and this report presents the results of these measurements along with some earlier results. The results compare tree diameter growth & net periodic total volume increment between thinned plots and control (unthinned) plots. Management implications of the results are discussed.
