Work package 8: Stand Model
A stand model of gap regeneration in beech forests will developed from existing models. Spatially explicit models for light (tRAYci, Brunner 1998), water (SOIL, Jansson 1998) and nutrients (e.g., SOIL-N, Eckersten et al. 1994) will be linked. The model development will synthesise the results from WPs 2, 3, 4, 5, 6, and 7. The model will be spatially explicit and represent the fine spatial variation of processes and structures in gaps. The model will simulate the distribution of primary resources in forest gaps and competition for these resources by seedlings of beech and the most important deciduous species present in central european beech forests (e.g., ash, maples, cherry, birch, oak). Establishment, growth, and survival of seedlings will be a function of resource availability. Growth of adult trees will be simulated using the individual-tree growth model SILVA (Pretzsch 1992). Decay of dead wood will be simulated using the decay model based on standard age/decay functions developed in WP 7. The probability matrix developed in WP 6 will be used to simulate plant and fungi species presence (using selected indicator taxa) on the decaying dead wood. Calibration parameter sets will be developed for input into WP 13.
