Abstract

In 1995, 3,746 hectare area of three north facing valleys was attacked by spruce bark beetle. Over the years 1986 -1990, 112 moss samples were collected throughout the attacked area adjacent areas. To identify the most adverse agent for forests stands, results of chemical analyses (Pb, Cd, Cu, Zn, Cr, Fe, Mn, Mo) have been submitted to multivariate analyses. Pattern of heavy metal accumulation in attacked area have been compared to the pattern of heavy metal accomulation in not attacked area. The following trends have been revealed: - Disproportion between increasing concentration of Cr and the other elements. - Increase of Mo in the tissues of moss samples collected on the southern slopes. - Increase in Cd and Cr concentrations in the samples collected inside the insect outbreak area.
