In the paper there are presented results of researches on flora and plant communities of the Paprotnia Range. These researches were carried out in the years 1993-1994. The following forest communities were distinguished in the range: Circaeo-Alnetum, Luzulo pilosae-Fagetum - the poor variant and variant with Anemone nemorosa, Tilio-Carpinetum typicum, T.-C. stachyetosum, the pine-oak community in the habitat of Luzulo pilosae-Fagetum, the pine community in the habitat of an oak-hornbeam forest. The paper contains also the map of real vegetation of the Range and the list of 265 species of bryophyta and vascular plants.

The structure of plant layers as well as diameters of trees in forest communities of the Paprotnia Range are presented in the paper. On the base of these results are characterized: the story of development, the present biological structure, the dynamic tendencies and the prognosis of future development of forest phytocoenoses. Described researches were carried out in the years 1993-1994 and are the continuation of researches on vegetation of the Paprotnia Range (A. Łuczak, M. Łuczak 2000).

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.
