The purpose of this study is to enhance the ecophysiological representation of single tree species within an existing mechanistic model, a pre-condition for assessing forest ecosystem restoration scenarios. We changed ecophysiological constants using published literature related to Norway spruce and common beech for a wide range of central European forests and evaluated model predictions using observations on stand transpiration, seasonal water balance, leaf area index, photoassimilation, tree volume, tree ring size, and soil and litter carbon and nitrogen content. A model validation, using an independent data set on tree volume, soil carbon and nitrogen content from a total 44 spruce and beech stands across the northern part of the Austrian Alps, exhibited no bias between model predictions and field observations.
