The objective of this paper is to present the effects of general changes in land use in recent decades on plant cover structure in Poland. The paper is focused on spontaneous processes that occur in agricultural and forest areas being no longer under human pressure. Studies carried out in different geobotanical regions of Poland demonstrated that the directions and range of dynamic changes in plant cover are similar across the country. The formation of secondary forest phytocenoses, on the lands delivered from human activity is a common ecological process observed today in the agricultural landscape. In the dynamics of forest vegetation the basic process is regeneration after ceased use, and the introduction of legal protection.

The Tomczyce nature reserve is characterized by a degenerated forest vegetation. We assume that the regeneration process was possible to launch after the establishment of the nature reserve in 1968. The vegetation of the Tomczyce forest complex was characterized for the first time by Jakubowska-Gabara (1976) whose studies were taken as a basis of our research. The phytocenoses after 40. years of protection have a greater participation of species with higher trophic and moisture requirements. The regeneration process in communities with pine trees is caused by an expansion of broad-leaved trees and shrubs. Transformation of forest vegetation causes a decrease in cover of thermophilous and heliophilous species. On the other hand, species of oak-hornbeam forests as well as anthropophytes are in expansion. Planning of the protection activities in the nature reserve needs to include these dynamic tendencies of the vegetation.

One of the key components of The Blue-Green Network in Łódź are valuable natural areas like the relicts of the natural wildlife (called “Green Treasures of Łódź”) which parts have been preserved in Łódź in spite of two hundred years, very intense urbanization processes. The result of years of geobotanical research in the city was establishing 23 areas of nature protection and proposing of 12 additional natural areas which need to be protected (8 areas of landscape protection and 4 ecological sites). Existing and proposed areas of nature protection, including river valleys, build the wildlife system of Łódź. Predominantly the important role in this concept play the Łódź’s river valleys with their vegetation potential. The Sokolowka River Valley which is located in the Northern-West part of Łódź was the exemplary research field for geobotanical and sozological valorization of the natural habitat of the Blue-Green Network. Within the Sokolowka valley there are retained fragments of precious nature ecosystems.
