Monitoring and Research

Regular assessements on around 6,000 Level I plots and more than 600 intensive monitoring plots (Level II) are a key objective of ICP Forests.

The systematic, large-scale monitoring network (Level I) provides annual data on forest condition, the intensive forest monitoring network (Level II) consists of permanent, highly-equipped plots to foster integrative studies on cause-effect relationships based on consistent long-term data series.

ICP Forests collects data on ambient air quality; biodiversity and ground vegetation; crown condition and damage causes; deposition; foliage and litterfall; forest growth; meteorology, phenology and LAI; soil and soil solution. An outstanding feature of the ICP Forests monitoring programme is its high degree of standardization of data collection and quality assurance in each survey and across all participating countries.
