Intensive forest monitoring (Level II) was created as an integrated part of the International Cooperation Program on Forests (ICP Forests) under the umbrella of the Geneva Convention on Long-range Transboundary Air Pollution (CLRTAP) and presents an important supplement to the area-representative Level I monitoring (Forest Condition Survey (WZE), National Forest Soil Survey (BZE))and allows a more detailed examination of cause-and-effect relationships at the ecosystem scale in forests.

In Germany, data from thirteen surveys is collected by the federal states on a total of currently 68 study sites based on a federal ordinance (ForUmV) since January 1, 2014. The data is subjected to quality checks and submitted to the ICP Forests database.
