Betrachtungsebene „Unternehmen“ air pollutants can be relatively easily observed, inventoried, and quantified. In the presence of sufficient dose, tree damage may be of sufficient severity to cause mortality. Tree death directly induced by ambient air pollution exposure is considered a Class III interaction and is treated in Chapter 16.

Forest Stress: Influence of Air Pollutants on Phytophagous Forest Insectsose that cause massive destruction in the short run, may play essential and beneficial roles in forest ecosystems in the long run. These roles may involve regulation of tree species competition, species composition and succession, primary production, and nutrient cycling (Huffaker, 1974; Mattson and Addy, 1975).

Die Elemente des Harzburger Modellswhich produces a pH of approximately 5.6–6.0. The pH of precipitation presently falling in North and Central Europe and in the northeastern United States and adjacent portions of Canada is commonly in the range of 3–5.5. Individual storm events have been recorded with pH values between 2.0 and 3.0.

All but the latter of these impacts would be extremely subtle, visibly asymptomatic, and detectable only by very careful forest monitoring.
