    Description

    Cultural practices can be applied in even-age stands to reallocate site resources to selected crop trees. Precommercial thinning in sapling stands can increase diameter growth and improve species composition of trees in the main canopy. Commercial thinning in sawtimber stands also increases diameter growth of crop trees, improves residual stand quality, and removes trees that would die absent thinning. Silviculturists need quantitative information on the response of particular species to thinning treatments to meet specific management objectives. In this study, 7- to 80-year-old northern red oak (Quercus rubra L.) crop trees in unmanaged, even-age central Appalachian stands were given various degrees of crown release. The response of released trees was compared to that of controls. Results of these individual trials, formerly published in numerous separate reports, are synthesized and combined with new information from more recent studies.
