Simulation of forest dynamics. Modification and parameterization of a forest succession model for Austria.
Abstract
A forest succession model of the JABOWA/FORET-type is parameterized and modified for alpine conditions of Austria. The environmental response functions which define the fundamental niche of tree species are evaluated with data from the Austrian National Forest Inventory and the Austrian Forest Soil Survey. The growth functions describing the species specific growth potential are parameterized with data from 480 open grown trees (OGT). The light regime is modelled for direct and diffuse radiation in a spatially explicit approach. Thereby the spatial explicit simulation of forest vegetation dynamics in a complex topography is possible.
