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.
