Level II

Intensive forest monitoring (Level II)

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.

For more information, please refer to the project brief (in German).

Available data

Level II data can be requested for scientific anaylsis

Surveys

The Level II monitoring consists of thirteen surveys within which data is collected: growth, ground vegetation, litterfall, phenology, ozone injury, foliar analysis, meteorology, air quality, crown condition, deposition, soil solution, soil, and leaf area index (LAI).

Interactive visualization

Interactive visualizations enable the illustration of results, the mapping of trends, and the comparison of different elements and tree species. For example, results on atmospheric nitrogen deposition or nutritional status can be displayed.
