The aim of this paper was inventory of the wild service tree (Sorbus torminalis), a very precious but, at the same time, one of the least known species of homeland wooded plants in the Taczanów Forest Inspectorate (Poznań Regional State Forest Directorate). The inventory was conducted from May 2010 to March 2011. The result of the inventory are 1127 specimens, of which 209 are strong mature trees and 918 are seedlings and young trees in good health. The field research shows that the wild service tree grows in the Taczanów Forest alongside its central and eastern part in 22 Forest Compartments, 8 of which are in the Koryta Forest District and 14 are in the Taczanów Forest District. The average height of mature trees (d1.3 > 10 cm) was 18.02 meters and the average breast height  dimension was 26.22 centimetres. The dominant forest type in this area which is acid oak forest from Quercetea roboli-petraeae class creates optimal conditions for the growth of the wild service tree. This is proved by an analysis of the species population dynamics which is characteristic for the species biology. The study shows that earlier inventories conducted in this region are incomplete and out-of-date, and this present inventory substantially broadens the knowledge about the wild service tree in the Taczanów Forest in the context of its local and national population.

The available phytosociological data and original observations were used for preparing a list of plant communities with Sorbus torminalis on its natural sites in Poland. The community context of its sites showed a wide range: from pine-oak forests (alliance Dicrano-Pinion) and oak forests (Quercetalia robori-petraeae, Quercetalia pubescenti-petraeae) to oak-hornbeam forests (Carpinion) and beech forests (Fagion). Oak-hornbeam forests (Carpinion) are the most frequent communities with S. torminalis in Poland. Despite this, oak forests (especially the open thermophilous forests of Quercetalia pubescenti-petraeae) seem to be the most suitable sites for growth and reproduction of this light-demanding tree species. Some remarks on S. torminalis conservation in the community context were also presented as its passive protection in some forest reserves has proved to be ineffective or even harmful.

Vegetation of deciduous forests in the Štiavnické vrchy Mts (Central Slovakia) was studied using the standard Zürich-Montpellier approach. The numerical classification and ordination technique were applied to determine the main forest vegetation types and to find the responsible environmental drivers related to their distribution patterns, respectively. The data set including 198 relevés collected by authors in 1997-2009 and 185 relevés excerpted from literature was used to analysis. Numerical classification resulted in delimitation of fourteen vegetation types representing eleven associations with two variants and two communities within the Quercetea roboripetraeae and Querco-Fagetea classes. The major environmental gradients in variation of forest species composition were associated with moisture and nutrient content following the average Ellenberg indicator values. Along the moisture gradient, vegetation types were ordered from subxerophilous oak forests turn mesophilous mixed oak-hornbeam, beech and ravine forests to hygrophilous riparian alder forest. The results confirmed important role of soil nutrients and moisture by determination of forest vegetation in subcontinental part of Central Europe. Special attention was given to the discussion of floristical characteristics, site conditions and syntaxonomy.

In 2009 and 2010, monitoring of conservation status and future prospects of the forest communities of Quercetea robori-petraeae Br.-Bl. et R.Tx. 1943 class was conducted in the Sudetes and their foothills. 31 sites were selected. At each site, three phytosociological releves were collected. An important component of the global assessment of oak forest communities is the occurrence of synanthropic species as measured by three indicators: occurrence of alien species (kenophytes), occurrence of synanthropic native species (apophytes) and occurrence of geographically alien tree species. At most sites, alien species and native expansive species were not observed or were represented by single specimens. For each site and releve, the index of synanthropization was calculated. The main role in the synanthropization of the investigated acidophilous oak forests is played by apophytes. The values for the synanthropization index suggest that this process is not advanced. However. the impact of synanthropization on species richness and floristic diversity of communities within oak forests is noticeable.
