The work deals with the issue of regenerating clearings due to salvage felling at mountain altitudes. Development was monitored on research plots Sokol in the Hrubý Jeseník Mts. (15 plots) and Jizerka in the Jizerské Mts. (15 plots). The aim was to assess the developing young plantations of Norway spruce, European beech, European larch and Carpathian pubescent birch in particular, as well as of sycamore maple, European mountain ash and Silesian willow aged 9 -- 14 years after planting. The assessment was focused primarily on the mensurational variables of the tree species (height, root collar diameter, crown diameter, and their increments). Part of the work was to evaluate the condition of soil environment, nutrition, root system architecture and health of Norway spruce. The best growth was shown by European larch. By contrast, the use of sycamore maple, European mountain ash and Silesian willow did not prove well. The mixing of Norway spruce and European beech was demonstrated to have a significantly favourable influence on the growth of the two species. The root system was confined to humus horizons only and all individuals exhibited deformation into a tangle. Analyses of soil conditions revealed that the effect of liming had persisted even after 20 years and the nutritional condition of the trees pointed to the luxurious supply namely of calcium and magnesium.
