The idea for this book arose in 1993, after the Free State of
Bavaria through its Bayrisches Staatsministerium rur
Landesentwicklung und Umweltfragen (Bavarian Ministry of Regional
Development and the Environment) decided to discontinue both the
Bavarian project management (PBWU) for forest decline research and
the multidisciplinary field research on the Wank Mountain in the
Alps near Garmisch. Forest decline through the action of ozone and
other photooxidants was a main topic of the supported re search in
the Alps and will be a topic of new investigations in the Bavarian
Forest. Many interesting results were obtained, but the researchers
involved have not had sufficient time to allow reliable conclusions
to be drawn. It was therefore decided to ask inter national experts
for contributions in order to summarize the best available evidence
of a possible link between ozone and forest decline - a topic which
has been studied in the USA since the late 1950s and in Europe
since the early 1980s. The original idea of Waldsterben as an
irreversible large-scale dieback of forests in Germany was soon
recognized to be wrong (Forschungsbeirat 1989). However, the new
criteria used for the official German and European damage
inventories (loss or yel lowing of needles or leaves, tree
morphology) indicate that per sistently high percentages of damaged
spruce and pine remain, and there is an increasing percentage of
damaged beech and oak, with a high proportion of biotic disease
(Forschungsbeirat 1989; UN-ECE 1995).
