This brochure summarizes the revised empirical critical loads for N compared to 2011. 40 % of ecosystems react more sensitively to N than previously assumed. The ecosystems studied have been visualized to make them easier to understand. Two maps show the distribution of natural and semi-natural ecosystems on the one hand and the distribution of forest ecosystems in Europe and the neighboring countries of Eastern Europe, the Caucasus and Central Asia (EECCA) on the other. This brochure was developed as a low-threshold information tool for scientists, but also for politicians and the interested public in the EU and the EECCA countries.
