Forests and their Dynamics
Forests cover roughly 30% of the earth’s land surface, but land-use and climatic change are modifying and threatening these ecosystems. To protect forests a better understanding of forest dynamics is crucial. Therefore, we have developed a family of process-based forest models: FORMIND and FORMIX. The models are used to simulate the spatio-temporal dynamics of mixed-species forests (uneven-aged) in combination with disturbances (e.g. logging, drought, stroms). The models calculate tree growth, tree mortality, the carbon balance of individual trees, competition for light and space, and recruitment processes by explicit seed dispersal. Our forest models have been applied in Malaysia, French Guyana, Ecuador, Paraguay, Brasilia, Mexico, Chile and Germany. We also use complex spatial statistics to get new insights into forest structures and dynamics.
