About the model
iLand is a model of forest ecosystem dynamics, simulating the processes growth, mortality and regeneration on watershed to landscape scale. Individual tree competition for resources and environmental influences on forest processes are explicitly modeled by iLand. The model is designed to investigate effects of climatic changes on forest ecosystem dynamics with particular focus on natural disturbances. It aims at harnessing these capacities for questions of sustainable forest management under changing environmental conditions.
| resources & growth | mortality & regeneration | application |
|---|---|---|
| growth | mortality | parametrization |
| resource availability and competition | regeneration | evaluation |
| constraints to resource utilization | management | scaling |
| soil dynamics |
About the implementation
The iLand modeling software is a software tool to simulating individual trees at landscape level. It is based on open source technologies and written in C++ using the Qt toolkit. Special development goals are performance, a rich GUI and extended scripting facilities.

iland-book
The "book" is a useful resource for both beginners and advanced users of iLand. It provides guidelines for getting to know the model, and covers advanced topics such as parameterization of new species. It complements this Wiki in providing a compact and accessible way to working with iLand.
