ForClim is climate-sensitive forest succession (“gap”) model, developed to simulate forest stand dynamics over a wide range of environmental conditions. The model is based on a minimum number of ecological assumptions to facilitate parameter estimation and analyses of model behavior. It is currently parameterized for 31 European tree species. ForClim has been tested for the representation of natural forest dynamics in the northern temperate zone of three continents. The latest version of the model features an extensive management submodel, comprising a wide range of silvicultural treatments. ForClim has been found to track time series data from growth-and-yield plots over 80-100 years remarkably well, and it can also be used under scenarios of anthropogenic climate change.
