Abstract Clearcut openings were created in mixed stands of southern New England hardwoods, hemlock, and white pines to observe the development of new stands in which all species started simultaneously. All preexisting woody plants, except beech root-suckers and very small seedlings of red oak and hemlock, were eliminated. Natural seedfall was augmented by direct seeding of some species. The main result, after 2 decades, was replacement of the predominant hardwood species of the old stand by black, paper, and yellow birch. Pin cherry and gray birch were initially prominent, especially near the centers of openings, but had died or become moribund. Hemlocks and white pines from new seed persisted in the bottom strata. Except for the birches and black cherry, the hardwood species of the previous stand showed little or no capacity to develop from seed that germinated after clearcutting and removal of advanced growth.

Mixedwood Stands

Abstract Many hardwood or mixedwood stands of northeastern North America have been high graded in the past and need restoration treatments to bring them back to an acceptable level of production. Even when early seedling establishment can be secured, further development may be compromised bymany factors. This study looks at the effect of seedbed, browsing, and competition on the growth and survival of yellow birch (Betula alleghaniensis Britt.) seedlings that became established after a brushing and scarification treatment applied in high-graded mixedwood stands of Quebec,Canada. The seedbed types studied include 1-m-wide scarified patches, 2-m-wide scarified patches, and mounds. Browsing impact was assessed by placing fences around half of the plots. Half of the plots were released from competing vegetation. Browsing by hare (Lepus americanus) was seenas a major factor controlling seedling development between 3 and 6 years after scarification. It reduced both survival and growth and obscured the effect of other factors. In the absence of browsing, competition had a major effect on mounds but not on scarified patches. Mounds were found tohave the best growth potential when competition and browsing were controlled. The scarified patches had the best growth when competition and browsing were allowed. Even though mortality was somewhat higher on scarified patches, initial densities were very high and still provide more seedlingsthan required.
