Blumwald: On Level II

[Translate to English:] Messnetz

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).

Study sites

As part of the Level II network, 68 study sites in Germany are currently operated by the forest research institutions of the federal states. The study sites represent environmental gradients (soil, climate, nutrient inputs) and includes forest stands with the tree species beech, oak, spruce, pine, larch, and Douglas fir.

History

The intensive forest environmental monitoring (Level II) originates from forest damage research in the 1980s. The widespread forest damage at that time highlighted the need for reliable data on forests and environmental influences. This data provides answers to research questions such as the effects of drought, which have become increasingly relevant since then.
