Plant communities in the lysimeter experiment of ash reclamation in the Dolna Odra Power Station in Nowe Czarnowo (Poland)

Abstract

12345Abstract. The aim of the study was to determine the type and origin of plant communities on an area of 4 lysimeters (35 m 2 each) filled with ash and covered with two superlayers 12 years after the beginning of the experience. The paper presents the species of grasses sown in 2003, their sward participation then and the florist status in 2015. Phytosociological records were taken using the Braun-Blanquet's method, distinguished plant communities, the syngenesis of the recognized phytocoenoses was defined. The results allowed to determine the advantage of the ruderal synanthropic communities: Artemisio-Tanacetetum vulgaris Br-Bl. 1931 corr. 1949, Leonuro-Ballotetum nigrae (in L-3), a community with Rubus caesius (in L-4) over the nat-272 R. GAMRAT et al. ural auxochoric Calamagrostietum epigeji Juraszek 1928 (in L-1). Their current state is referred to as a hull form. However, due to the presence of the expansive species characteristic of the above-mentioned communities, continued development can be expected towards fully developed phytocoenoses. The thesis founded about the influence of the neighboring forest communities on the species composition of the vegetation of the subject has not been confirmed. There were only three forest and scrub species with a negligible sward participation.
