Abstract:Published information indicates that cleaning among sapling-stage northern hardwoods has value for maintaining species that might otherwise become overtopped and lost from a stand. Cleaning will also stimulate the diameter growth of trees in upper crown positions, but may delay the dying and self-pruning of lower branches and thereby affect tree quality. Removing adjacent trees that touch the crowns of a selected number of crop trees has proven efficient and effective. However, field tests have not yet provided growth and yield data for assessment of the long-term effect on tree quality, or the economic benefits from such treatments. North. J. Appl. For. 8(3):111-115.
