Postępujące niekorzystne zmiany w składzie gatunkowym runi łąkowej w siedliskach pobagiennych, zwłaszcza na terenach objętych ochroną prawną, wskazują na konieczność poznania mechanizmów kształtowania się jej struktury i walorów. Celem pracy było określenie struktury runi zbiorowisk łąkowych o zróżnicowanym udziale Arrhenatherum elatius i Bromus inermis ukształtowanych w wyniku zaniechania użytkowania,...
Scots pine stands are the most important forest type in Poland and the differentiation of the natural vegetation in these forests is well known. However, the intensive utilization causes the formation of the secondary communities, so that further studies of the vegetation diversity should be carried out with taking into consideration stand age and homogeneity of site conditions. The aim of this work...
Na przestrzeni ostatnich lat w kształtowaniu składu gatunkowego upraw rolniczych coraz większe znaczenie odgrywają czynniki agrotechniczne wynikające ze zmian w produkcji rolniczej. Celem badań prowadzonych w latach 2004-2012 była ocena zmian zachodzących na prze¬strzeni lat w składzie ilościowym i jakościowym zbiorowisk chwastów towarzyszących upra¬wie kukurydzy wynikających z wprowadzonych do jej...
The study was carried out in 2011–2013 at selected complexes of Molinia meadows located in Bagno Bubnów (Polesie National Park). Tested complexes were characterized by the dominance of Molinia meadows, which bordered to other plant communities. The study area was characterized by a large number of plant species under strict and partial protection. Ostericum palustre, species protected by Habitat Directive...
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).
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...
