Logging Practices and Subsequent Development of Aspen Stands in East-Central Saskatchewan

Abstract

A study was started in 1965 to quantify the effect of logging variables on initial sucker stand density and subsequent development of aspen (Populus tremuloides Michx.). The study found excellent stocking and density of sucker regeneration after both summer and winter logging of 70- to 80-year-old stands in east-central Saskatchewan. Logging slash on the ground reduced suckering but the density of regeneration even with heavy slash cover was similar to that found in fire-origin stands. Winter logging resulted in more uniform and less dense sucker regeneration. Large initial differences in stand density diminished to a 30% range or less by 5 years of age. This suggests that flexibility may be exercised in harvest scheduling and method of logging.
