The objective of the article is a short and instructive introduction to model approaches for pure and mixed forest stands from yield tables to eco-physiological process models. A model's objective and the existing knowledge of the observed system determine how complex the model approach has to be. Single tree models, eco-physiological based gap models and hybrid models are of particular interest for forest management as they are suitable for pure and mixed stands and a broad range of climatic zones. Version 2.2 of the SILVA model, developed for pure and mixed stands, belongs to the promising category of hybrid models and is used to explain the functional principles underlying this model approach. The SILVA stand simulator provides quantitative growth and yield information as a decision support for forest management.
