Abstract

Effects of tree age, month of cut, and height and angle of cut on sprouting of red alder stumps were evaluated in a study designed to develop an effective method for controlling red alder in Douglas-fir plantations. Ninety-five percent or more of alder stumps cut in June or July died by the end of the next growing season; mortality was 88, 70, and 22 percent for stumps cut in May, August, and September, respectively. Stumps of 4-year-old alder trees tended to have higher survival and taller sprouts than did stumps of 6- to 10-year-old trees. Height and angle of cutting had little influence on sprouting. Red alder can be controlled effectively by using cutting guidelines developed from these results.
