In this paper we introduce and enhance the biogeochemical model BIOME-BGC within forest ecosystem restoration by applying it for a secondary Norway spruce and common beech stand. Data for testing the model calculations came from the permanent research plot in Kreisbach, Lower Austria. We compared key parameters of the water-, carbon- and nitrogen-flux for the two different forest ecosystems. The results demonstrate consistent variations of the input data versus the variations in the output data. Daily differences as well as long variations in climate input were maintained by the model. Calculated data on the seasonal water balance, the leaf area indices, timber production or the nitrogen status matched the measurements.
