Results of the statistical tests showed the spectral disparity of the production part and highly damaged juvenile part of the spruce crown. A spectral difference of the juvenile and production crown part at early stress could not be shown. A low multiple stress impact was assessed for 75 randomly selected Norway spruce trees of the first AISA image. In case of the second AISA image occurrence of Cu-Zn sulphide mine partly influenced the crown status of the neighbouring spruce ecosystems
