TRAGIC++ is an interactive forest stand simulation program.
In TRAGIC++, the development of a forest is simulated as the collective dynamics of individually growing trees, each of which competes with the others for light, space and nutrients. Interaction is possible by removing or planting single or groups of trees and by changing the environmental conditions (light an nutrients).
The TRAGIC++ program is based on a relatively simple process-based tree growth model that can be parameterised to represent trees of different species.
