In 1998, three years after technical and biological reclamation, 29 relevés were made in the ridge area (the crown of the excavation) of the quarry “Piotrawin”. Two segetal associations were distinguished (Sileno inflatae-Linarietum minoris and Lathyro-Melandrietum noctiflori) as well as one xerothermic grassland association (Inuletum ensifoliae). The communities are floristically very rich. The number...
The aim of this study was to characterize the occurrence of Calamagrostis epigejos in communities in different biotopes (industrial waste clarifiers, sand and gravel pits, abandoned airports and military training grounds, urban areas, roadside, long-term fallow land, forest roads and parking lots near forests) in the western part of Western Pomerania and Lubin Upland (Gilów clarifier). This paper...
Western ragweed (Ambrosia psilostachya DC.) is an invasive species recorded in Poland in few sites. In the area of western Szczecin Lowland it is the 3rd site. The community with ragweed occurs on the roadside of a two-lane Berlin–Szczecin–Chociwel highway on soil formed by sands (slightly loamy and light loamy), desiccated, slightly salinized, with neutral pH, and with low content of humus and CaCO3...
Floristic differentiation, the number of species in segetal communities and the mean number of species in relevé depend on a series of natural and agrotechnical factors. Differentiated soil conditions are a significant natural factor. Along with an increase in the trophic character of a soil and its moisture content the number of species in communities grows. In a typical variant of segetal communities...
The analysis of the geographical and historical structure of the flora of different biotopes and the anthropogenic indices are of cognitive significance in the process of transformation of communities. Differentiated biotopes (exploited sand and gravel pits, fallows, arable fields, warm slopes, shrubs, alleys, midfield ponds and midfield meadows, forest habitats, shoulders of forest roads and car...
Badanie zbiorowisk roślinnych z obecnością solidago canadensis L. i S. gigantea Aiton przepro-wadzono w dwóch zróżnicowanych biotopach - na wieloletnio odłogowanych polach uprawnych oraz porzuconych łąkach przyleśnych. Odłogowane pola uprawne charakteryzują się występowa¬niem dwóch typów gleb - czarnych ziem zdegradowanych (Dz) i gleb brunatnych właściwych (B). Wytworzone są one głównie z gliny lekkiej...
The objects of research were 55 mid-field meadows of an up to 5 ha area, the characteristics of which were biotope conditions and the method of exploitation. The area is localized in the western part of Drawskie Lakeland. The field research was carried out in the years 1995–1999. In this period 150 phytosociological relevés were made using the Braun-Blanquet method. Collective soil samples were taken...
