One growing season after the harvest of a 16-year-old hybrid poplar (Populus sp.) plantation, sprouts from 100 clumps were thinned to retain the dominant sprout; 100 clumps were left for comparison. After three growing seasons, thinned and unthinned clumps did not differ in total number of sprouts per clump or in diameter of dominant sprouts. Dominant sprouts were significantly taller in the unthinned clumps. Thinning hybrid poplar sprout clumps after a harvest is not recommended.
