Eine Methode zur Erfassung von Verlauf und Grad der Schädigung von Nadelbaumbeständen

A procedure for the registration of the time course and degree of injury in conifer stands. Missing tree rings are detected by dendrochronological methods and systematically recorded. A procedure is described for the registration of the time course and the extent of injury in conifer stands. A highly significant correlation is demonstrated between the extent of injury in European Silver Fir and the average sulfur content in Norway Spruce needles on the basis of the bioindicator network of the Bayer. Landesamt für Umweltschutz; sulfur content in spruce needles is taken as a measure of sulfur burden of an area.
