Forest environmental monitoring is established throughout Germany and provides reliable data and findings on the condition and development of forests. The “Forest Environmental Monitoring” area of work is responsible for the operation, data collection, quality assurance and reporting of the forest environmental monitoring networks. This includes the soil condition survey (BZE), the deposition measurement network, the Level II substance flow measurement network, the forest condition survey and ten forest climate stations. The measuring networks provide the data basis for topic-specific evaluations of all other work areas of the department, especially for questions relating to the material balance of forests and for climate impact research. The data collected flow directly into policy and recommendations for forestry practitioners.
