Forest damage normally is characterized by loss and yellowing of leaves or needles. The results of this ocular damage diagnosis can be confirmed and stated more precisely through biochemical criteria, e.g. the plant hormone ethylene, the activity of the enzyme phosphoenolpyruvate-carboxylase (PEP-C), the content of chlorophyll and other biochemical parameters. Therefore we investigated the interrelation between visible damage and 13 biochemical parameters in six trees each from eleven permanent observed sites in the south-west of Germany. The results indicate that damaged trees can be separated clearly from undamaged trees by these biochemical criteria. Furthermore, statistical evaluation of the measured data allows to detect causal connections. Factor analysis lead to two factors which divide the investigated parameters into two groups, each indicating a different causality.
