Climatic changes affect minor resistance and vitality of the forest, incidence of natural disturbances increases. In this research we compared efficiency of natural and artificial restoration of forests affected by natural disturbances; the stress was laid on structure and growth of seedlings, impact of ground vegetation, and importance of seed trees. The first study compares success of regeneration according to three diverse treatments (1: preparation of soil, sowing, fencing; 2: sowing, fencing; 3: sowing and planting). In the second research we compared success of natural regeneration and artificial regeneration (planting) after windthrow. The results show that regeneration is positively affected by proximity of seed trees and soil preparation, while the impact of ground vegetation cover is negative. The densities of naturally grown seedlings on plots with natural regeneration surpass the ones on plots with artificial regeneration (disregarding planted seedlings).
