Opis:: Glades are an important element in the landscape of the Gorce Mts. (southern Poland). The cessation of use of the glades triggered the spontaneous process of landscape development − renaturalization, leading to their gradual overgrowing. The paper presents the results of research on the renaturalization of 46 glades situated in the upper montane belt in the Gorce Mts.

Opis:: One of the most important objective of the active nature protection in national parks situated in Polish mountains is the restoration of mixed stands replaced by Norway spruce monocultures. Seven spruce stands situated in the Tatra National Park were measured in 1983−1986 and in 2001. The density of all stands decreased whereas the basal area and volume increased. In some of them the changes were considerable. The contribution of Fagus sylvatica and Abies alba, two most important tree species in natural mountain forests, changed only slightly and even decreased in three stands. Intensity of elimination of trees was related to their thickness – thin trees were removed from stands more often. Due to this way of thinning the variation of tree thickness diminished in all spruce stands. The densities of Fagus sylvatica and Acer pseudoplatanus saplings increased in all stands as a result of former planting. However, they are still to low for effective restoration of mixed stands. It can be concluded that mainly sanitary cuttings have been used recently in all stands. This line of management is not deliberately focused on the restoration of mixed stands and the diversification of their structure. It results in aging of dense spruce stands and increases the risk of future large−area disturbances due to strong winds and insect outbreaks.
