Abstract
After years of data collection in mixed species stands a new version of the distance dependent single tree model SILVA can be parameterized for mixed and pure stands of spruce and beech. Models for predicting crown intersection and crown diameter are developed, potential relations between tree height, tree diameter and site factors are given. In addition models for predicting height increment and diameter increment are derived, mortality functions and multi dimensional distance functions for generating stand structures are presented. All models include parameter estimates and their standard errors respectively, plots of the residuals are scetched too.
