Effect of Release Upon the Form and Volume of Western Yellow Pine
Abstract:A study of western yellow pine in selectively cut stands in Oregon and Washington shows that there is a progressive change in form dating from the time of release. Previous to release the trees, irrespective of form class, tend to improve in form, while directly after the release cutting all form classes tend to converge in a single belt, in which form class 0.725 is the most significant. It was found also that volume tables in use for virgin stands apply equally well for stands released for various periods.
