Abstract: Data collected from a young, even-aged northern hardwood stand in central New York revealed differences in species composition and patterns of development between permanent plots having a high and low stem density of pin cherry (Prunus pensylvanica L.f.) Twenty years after clearcutting, pin cherry dominated the high density plots. It persisted only as large, scattered individuals among low density plots. Low density plots had about three times more dominant and codominant stems of species other than pin cherry, including over five times more dominant black cherry (Prunus serotina Ehrh.), and dominant and codominant sugar maple (Acer saccharum Marsh.). Dense patches of pin cherry appeared to inhibit other trees from growing into the general level of the main crown canopy. After pin cherry dies, all plots will contain a mixture of shade-tolerant and shade-intolerant species. However, high density areas will have fewer sugar maple and black cherry, and an overall low density of surviving stems.
