Webb22 aug. 2013 · Variable-density thinning is often applied in young stands and is commonly viewed as a restoration treatment that enhances wildlife habitat in the developing stand or sends the stand on a trajectory toward a desired structure. However, the primary intent of variable-density thinning is to increase, if not maximize, within-stand heterogeneity. Webboptimal stand-level management strategies. Improved models that include a thinning response will provide forest managers with a better tool for planning stand level manage-ment of Norway spruce. The objective of this study was to develop a stand-level model for forecasting growth and yield of thinned and unthinned Norway spruce stands.
