Abstract

The purpose of this paper is to derive yield tables for beech. The material consists of 39 permanent sample plots in beech stands. The development of top height during the study was used as the basis for deriving height development curves. With the aid of these, individual stands were referred to a certain height quality class, defined as the top height of the stand at a total age of 100 years. In constructing the yield tables, top height was assumed to follow the derived height development curves. Basal area increament as calculated by a function obtained by regression analysis, with the help of the material. The yield tables reproduce the average stand development and yield when site quality class, the initial stand and the thinning programme are given. In individual stands, yield deviates from the table, as a rule. The deviations depend partly on experimental error, e.g, errors in estimating basal area increment, and partly on the influence of factors not taken into account by variables in the increment function. In using the tables, such local deviations should be taken into account. The sample plots reviewed here should in many cases be suitable for this purpose.
