The dendrogram of Czekanowski index remaining plants and many weed seedling came up suprisingly quickly. The spring of 1982 supplied with Tilia and Quercus seedlings the gaps of the thinned clearings. At present we cannot judge whether the tree seedlings will grow up while the old Pinus nigra stand dies. Nobody knows what kind of change will be caused in the grass layer because of the changes in the litter. Changes in the pine and deciduous leaf litter involve complete changes in the decomposer microfungal flora. This results in changes in part of the moss flora. It is to be expected that the ferns of the 'Ebgondolta' forest will gradually die because of the changes in the woodland.
