    Description

    Group selection harvest studies in Eastern hardwoods have shown that economic success of such harvests rests heavily on product market values, tree quality, and logging costs (Boucher and Hall 1989; Bell 1989). Other studies have attempted to define group selection harvests and where they can be used (Roach 1974). Additional studies have documented the reproduction of hardwoods 10 years after cutting as affected by site and opening size (Minckler and Woerheide 1965). In this study, the group selection units are defined as small groups, .81 ha (2 acres) or less in area, on which most of the trees will be harvested.
