This chapter compares the Criteria and Indicator approach of the Montreal Process with the European approach to derive environmental policy options by identifying critical loads for atmospheric deposition. After an overview of the main changes in soil chemistry resulting from excessive soil acidification, it discusses the Montreal criteria and indicators most relevant to acidification one by one in the light of research in Europe. The four discussed criteria are: conservation of biological diversity; maintenance of productive capacity of forest ecosystems; maintenance of forest ecosystem health and vitality; and conservation and maintenance of soil and water resources. Genetic diversity can possibly alter due to excessive soil acidification by extinction of acid-sensitive species or subspecies. The influence of the pollutants nitrogen and sulfur via soil on tree health is exerted by means of soil acidification and eutrophication.
