The Effect of Spacing on the Growth of Norway Pine Plantations--A Progress Report
Abstract:Opinion concerning what constitutes proper spacing for coniferous plantations has changed considerably during the past thirty-five years. There appears to be a tendency to increase the spacing of coniferous plantations. Although the authors are not yet ready to draw final conclusions their work on sixteen-year-old Norway pine planted in Pennsylvania indicates that spacing up to 10 by 10 feet results in rapid diameter and height growth and may be advantageous when the trees can be pruned.
