Abstract

The effects of four cleaning practices (including a control) on species composition and structural characteristics were studied over a 31-year period following treatment of an even-aged 25-year-old northern-hardwood stand that originated after complete clearcutting in 1933–1935. The treatments consisted of: a heavy and a light crop tree cleaning; a drastic species-cleaning treatment that removed nearly all pin cherry (Prunus pensylvanica L.f.), aspen (Populus tremuloides Michx. and grandidentata Michx.), striped maple (Acer pensylvanicum L.), and red maple (Acer rubrum L.) sprout clumps followed by a crop-tree cleaning; and an uncut control. There were no significant differences among treatments in species and structural characteristics in the 56-year-old stand at the end of the study period, except for the presence of a moderate aspen component in the light cleaning and the control. Although previous research shows that cleaning treatments in young northern hardwoods may have silvicultural and economic benefits, the impact of such treatments on long-term stand development is relatively minor.
