Relationships between Forest Condition and Natural and Anthropogenic StressFactors on the European Scale; Pilot Study

摘要

Ten years of defoliation data for six tree species of the systematic forestcondition monitoring network have been correlated with site-specific estimations of various stress factors, both natural and antropogenic. The stress factors include available and interpolated soil data, interpolated and modelled meteorological data and modelled air pollution and deposition data. Various threshold values were included, e.g. site-specific estimations for the critical deposition levels. The results were highly affected by methodological differences countries. On top of this effect, age is an important factor, followed by different natural and anthropogenic stress factors, depending on the tree species.
