Abstract:Any evaluation of plantation management regimes which include one or more thinnings requires information on the growth and yield response to thinning. A procedure is proposed by which the predicted basal area growth and yield in thinned plantations is derived from unthinned plantations of the same age, site index, and number of stems per hectare as remain in the thinned plantation immediately after thinning. An estimate of growth after thinning is obtained by adjusting the projected growth of the unthinned plantation to allow for the degree of suppression that existed in the thinned plantation, relative to the unthinned counterpart. Different thinning intensities and thinning methods can be accommodated within the proposed general formulation, so that it can be used to evaluate the potential role of thinning in plantation management.
