Estimation of Population Size of Dentaria Enneaphyllos in the Vicinity of the Bełchatów Brown Coal Mine and the Attempt of its Metaplantation Kurowski, Józef; Koczywąs, Ewelina; Pieńkowski, Michał The impact of anthropopressure on the flora in the vicinity of the Bełchatów Brown Coal Mine in Central Poland has been substantially strong. Consequently, certain changes in habitat conditions have been observed, leading to a decline in particular species stands. Mechanical damage, as well as the mine and power plant expansion have contributed to further species decline in the area. Ex situ conservation, e.g. metaplantation from native to secondary localities seems an efficient method of ensuring the species survival in the local flora. One of the species is to be found in Wola Wydrzyna (under the Forest District Administration of Bełchatów) is Drooping Bittercress Dentaria enneaphyllos. Its population was first recorded in the area in 1979. However, since 2009 the forest complex has undergone a regular expansion of the Bełchatów Brown Coal Mine. The forest area is to be utilised for the future Szczerców coal deposit. Therefore, in 2000 the method of Dentaria enneaphyllos metaplantation was applied.

Reaction of Coniferous Forest Vegetation to Particulate Deposition Under Alkaline Pressure Świercz, Anna The aim of this study was to determine direction, rate and character of the changes in coniferous forest communities caused by anthropogenic stress factors (alkaline emission and imission) changing with time. To fulfil this goal, we have performed comprehensive studies of soils and plants at the study sites located in coniferous forest communities remaining under direct influence of cement and lime industry in the Świętokrzyskie Voivodeship. There were differences in the accumulation of elements in pine needles collected at alkalized sites in comparison with needles from the control site: Ca content was 2.5 times higher and Cu, Pb and Sr contents were 2-3 times higher, while Al and Fe, and Mn contents were twice and 10 times lower respectively. SEM analysis of morphological features of pine needle surface, in particular degree of preservation of epicuticular waxes can be as an indicator of assimilatory organ degeneration caused by dust deposition which induces wax layer erosion. Declining species number and biodiversity, particularly conspicuous at the Sitkówka site, was a general tendency observed over the study period (from 18 to 10 years). Other noticeable processes include slow regenerative changes of the community with a tendency towards higher contribution of acidophilic coniferous forest species with lower light and temperature requirements and suppression of meadow, ruderal and associated taxa. Further studies are required in order to define succession rate and direction of changes in species composition of these communities.

An Attempt at Assessment of Alnetum Incanae Lüdi 1921 Transformations in the Skawica River Valley (The Beskid Żywiecki MTS) Skowronek, Izabela; Babczyńska-Sendek, Beata; Chmura, Damian The paper presents an attempt at assessment of Alnetum incanae LÜDI 1921 transformations in the Skawica River valley. The field studies were carried out in the whole Skawica valley. On the basis of phytosociological relevés, the participation of species which prefer riparian habitats, the number and cover of anthropophytes, including invasive plants, were analyzed. The presence of synanthropic sites was also taken into consideration. The research demonstrated that in the study area phytocoenoses of the Alnetum incanae association have primarily retained natural character, in spite of a noticeable influence of human impact. The results suggested that the vicinity of synanthropic sites does not eliminate natural components of phytocoenosis.

Transformation of Forest Vegetation After 40 Years of Protection in the Tomczyce Nature Reserve (Central Poland) Kiedrzyński, Marcin; Zielińska, Katarzyna Maria; Grzelak, Paulina 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.
