The paper presents the characteristics of Sudeten grasslands (species composition, floral diversity and habitat parameters) from the perspective of diversified management. On the sites examined, hay meadows were found with Arrhenatheretum elatioris, variant with Trisetum flavescens and pastures of Lolio-Cynosuretum. Mowing and grazing promoted floristic diversity. There were few grass species. On...
The conservation status of the communities of the class Asplenietea trichomanis was studied in 2010 in southern Poland. In all, 81 sites with rocky plant communities were selected, and 270 phytosociological relevés were collected. Alien species were found at 27% of the sites. This indicates that the rocky communities there are exposed to strong pressure of plant invasion. The most common alien species...
This paper presents the environmental conditions, floristic structure and distribution of the Ranunculo-Callitrichetum hamulatae Oberd. 1957 em. Müll. 1977 from the Potametea R. Tx. et Prsg. 1942 class in the four metallurgic canals in the Opole Silesia (SW Poland).
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...
The aim of the present study was to determine changes in in the nature of plant communities and to determine general trends in environmental transformations along the middle Vistula valley during the last 25 years. The area studied encompasses part of the floodplain within the borders of Łomianki commune, a suburban district of Warsaw. The study was based on the analysis of two maps, one compiled...
Presented in the paper are characteristics of the meadow communities and assessment of the degree of their synanthropization. The studies were conducted on meadows utilized in Walim District at the base of the Sowie Mountains in 2009 and 2010. Floristic releves were collected using the Braun-Blanquet method. The material obtained served to define the phytosociological affiliation and to estimate the...
