Development of tree species planted on the bare land and under the stand decaying under the impact of air pollutants

During the period from 1985 to 1990 the applicability of selected tree species (common spruce, European larch, Swiss mountain pine, European birch, rowantree, European beech, sycamore and European green alder) to the reforestation of air polluted regions had been studied as well as their reaction to...

Summary:During the period from 1985 to 1990 the applicability of selected tree species (common spruce, European larch, Swiss mountain pine, European birch, rowantree, European beech, sycamore and European green alder) to the reforestation of air polluted regions had been studied as well as their reaction to different environmental conditions of bare lands and to those under the decaying spruce stand. In the majority of cases the culture of individual tree species reached lower average biomass heights and weights under the stand than on the bare land. The impact was most intensive in Swiss mountain pine, than in birch, larch and spruce, and least in beech and European green alder. A higher total damage of tree species was recorded under the stand than on the bare land. This is given by more intensive grazing of cultures by game and by higher mechanical damage caused by the fall of snow and icing down from tree crowns. Rowantree, sycamore and beech were most subjected to game browsing, beech was subjected to rodent feed, birch and larch to game frying. The damage degree of mountain pine and green alder was very low. There was found a higher sulphur content in the needles or leaves right below the tree crowns than on bare lands. In the light of results it can be stated that the underplantings of decaying spruce stands, caused by significant imission stress are biologically and technologically feasible.
