The cumulative habilitation thesis summarizes 23 articles on the exposure of forests to atmospheric heavy metal and nitrogen deposition and the resulting changes in ecosystem integrity linked to climate change. It comprises a complete research data management and is based on a synoptic systematization of studies that were presented and discussed at international conferences during the years 2014-2018 and published in international peer-reviewed journals. The UNECE European Moss Survey (EMS) of

For the 2015 survey, the German biomonitoring network was reduced from 726 to 400 sites compared to the 2005 campaign. The restructured moss network 2015 is still harmonized with other environmental monitoring networks in Germany (ICP Forests, ICP Integrated Monitoring, Environmental Specimen Bank). Its restructuring took place without significant losses in the statistical validity of the measurement results compared to 2005. The results of the German contribution to the EMS 2015 reveal a clear, significant decline in the concentrations of mosses for most of the heavy metals (1990-2015), but not for nitrogen (2005-2015) and mercury (1995-2015, in six federal states). Four studies again demonstrate the suitability of ectohydric mosses as biomonitors for the atmospheric deposition of Cd and Pb (Norway, 1995-2005, Europe, 2010) as well as N and Cu (Europe, 2010). The spatial density of agricultural (As, Cd, Cr, Pb, N), forestral (Hg, Ni, V) and urban-industrial land use (Cu, Zn) within radii between 75 and 100 km around the moss sampling sites, distance to emission sources (As, Ni), precipitation (As, Cd, V), and altitude (As, Pb, Hg, V) were detected as major factors influencing the element concentrations in mosses, in addition to the deposition rate. Similarly, there are significant statistical correlations between heavy metal concentrations in the uppermost 3 cm of the natural surfac [...]
