The BZE characterises the condition of forest soils, identifies changes in forest condition since the first inventory and answers any new research questions, e.g., about carbon inventory.
The BZE represents a national, systematic sampling inventory of the condition of forest soils. The first BZE inventory (BZE I: 1987-1993) was carried out on a systematic 8 x 8 km grid on the same sampling plots adopted in the forest condition survey (WZE). In some areas the network of sampling plots involves 1900 grid points. The first BZE I field survey was repeated after 15 years, between 2006 and 2008, by the national and the state authorities in cooperation. Afterwards, extensive laboratory and statistical analyses were conducted.The Thünen -Institutes of forestecosystems coordinates the evaluation with 35 experts. The ferdal states are resonsible for the assessment, anaylsis and evaluation of their own data.
The national forest inventory focus on.
- Status and changes of soil and forests condition
- Impacts on envirnomental factors like atmospheric deposition or climate on soil and crown condition, growth, vegetation and tree nutrition as well as biodiversity.
