A parameter-based method for determining thinning intensity

Abstract

A method for quantifying thinning intensity in experimental trials in even aged stands is proposed. The method (ICN) is based on Assmann’s theory and assesses thinning intensity in terms of percentage of basal area to be removed. According to the proposed method, maximum stand basal area of an even-aged stand is expressed in terms of its dominant height. The ICN index was used to quantify thinning intensity in an objective and replicable manner in experimental comparisons among different thinning intensities in black pine reforestations in Tuscany (Italy).
