In this chapter we demonstrate different management regimes and their impact on commercial timber supply using the individual-tree growth simulator PrognAus for Windows 2.2. We thereby address two frequently discussed scenarios: (1) the conversion of even-aged pure species stands into uneven-aged mixed species stands and (2) how to deal with a forest stand whose trees are damaged by bark peeling. For both scenarios we show how growth and yield, timber supply and commercial assortments change under different management regimes. In addition we provide an economic evaluation of these management regimes. The results of our demonstration runs indicate that a thoroughly developed individual-tree growth simulator is an excellent tool for scenario analysis.
