In Central Europe traditional forest growth modeling, i.e. the development of growth and yield tables, has a history of more than 200 years. Other approaches such as individual-tree growth modeling became established during the last three decades. Nowadays, a number of different model classes and modeling approaches exist which can be used for different purposes. Currently, great efforts are taken to link different modeling approaches (e.g. hybrid models). The focus of this compilation was on forest management models that operate at the individualtree level. These models were originally developed to predict future growth and yield of the various forest types. Because of their high flexibility, they were throught to be an alternative to the classical yield tables. Nowadays, these models are well established and used for forest management, research, and education. The main components of an individual-tree based forest management model are equations for estimation diameter and height increment, mortality, and regeneration (tree recruitment). Additional components are used for updating tree attributes such as crown dimensions (Ledermann, 2011) and to estimate tree compartments like branch and needle biomass.
