Abstract

“Wartowice” tailings pond was closed in 1989, resulting in 232,4 ha tailings pile requiring reclamation. The major problem is heavy metals presence and poor nutrient conditions and physicochemical structure of soil which disturbs the plants development. In order to assess the real condition of studied area the complete biological characteristic has been done. The physicochemical conditions were assessed altogether with phytosociological, microbiological and toxicological studies of deposits. We recorded only 27 species of vascular plants belonging to 15 families on the tailings pond of which 5 belong to Rosaceae, 4 to Asteraceae and 3 to Poaceae and Saliceae. Species inhabiting the tailings depended on their dispersal capacity, metal tolerance and rhizome strategy. Microbiological analyses revealed the low number of bacteria and fungi on the tailings pond, apart from the small uplift area where the plants were indentified. Bacteria identified on the tailings pond were classified to 8 genera. The low number of bacteria suggests the lack of nutrients which affects the development of soil microflora. Toxicity tests showed that post-flotation sludge is not toxic to microorganisms because of its high pH. Some plants, such as lucerne could even influence positively the microorganisms development what has been proved in our studies. The tailings toxicity was higher towards producers, where Secale cereale appeared to be the most sensitive species. Amendment with topsoil from adjacent areas can influence positively the phytotoxic properties of tailings and enrich them into native seeds.

Abstract

Natural water reservoirs in Europe are very valuable floristic sites. Among them, springs are very important for the preservation of the biodiversity of flora in Poland. The present paper presents a community of water plants that is new to limnocren karst springs in Poland – Potame-tum pectinati Carstensen 1955 from Potametea class. In Europe this community in limnocren karst springs has not been found so far. The paper presents the floristic composition and the ecological requirements of this association.

Abstract

Paper presents the description and floristic and ecologica characteristics of three plant communities on the area of Jasnorzewski Gardens in the region of Arctowski Station (Polish Academy of Sciences) on King George Island. They are: 1) Deschampsio antarctici-Colobanthetum quitensis, 2) Polytrichetum alpini, 3) Calliergidio austro-straminei-Calliergonetum sarmentosi. All communities show a considerable differentiation to several variants. Distribution of plant communities on the studied area is presented on a map based on computer analysis of multispectral air photographs.

Abstract

Water reservoirs are very valuable floristic sites in Poland. Among them, the most im-portant for preservation of biodiversity of flora are fishponds. The long-term process of human pressure on habitats of this type caused disturbance of their biological balance. Changes in the water regime, industrial development and chemisation of agriculture, especially in the period of last two centuries, led to systematic disappearance of localities of many plant species and plant communities. Gnaphalio uliginosi-Eleocharitetum acicularis Passarge 1999, of Isoëto-Nanojuncetea class Br.-Bl. et Tx. 1943, was firstly described in Germany. This association grows on sandy or sandy-gravely banks of rivers and in old river beds. In Poland, Gnaphalio uliginosi-Eleocharitetum acicularis has not been found so far. The patches of this type have been described many times, but otherwise classified acording to syntakxonomical system. During current vegetation research the association Gnaphalio uliginosi-Eleocharitetum acicularis was found in seven fish-breeding ponds in south-western Poland. Fieldworks were conducted in 2000–2016.

Abstract

The article describes the vegetation growing on settlings and washing tanks situated in the ,,Żabie Doły" area (Bytom). There were recognised 2 plant associations and 6 plant communities which belong to Artemisietea, Molinio-Arrhenatheretea, Calluno-Ulicetea classes. Among them dominate communities from Dauco-Melilotenion suballiance which are confined to dry, permeable soils with the initial soil-forming process (Melilotetum albo-officinalis, Dauco-Picridetum hieracioidis. Calamagrostis epigejos community, So/idago canadensis community). There were recorded also swards (Festuca ovina community) and meadows tDeschampsia caespitosa community, Agrostis capillaris community).
