Pogorzelec et al.: Relict boreal willows (Salix Lapponum and Salix Myrtilloides) as an element of phytocoenoses Overgrowing the water bodies in Eastern Poland -441 -APPLIED ECOLOGY AND ENVIRONMENTAL RESEARCH 12(2): 441-456. Abstract: The aim of the present research, which was conducted in the years 2002 and 2012, was to determine whether and to what extent the biocenotic changes taking place in the aquatic peatland ecosystems affect the state of the populations of endangered boreal willows
... boreal willows (Salix lapponum and Salix myrtilloides) in the Łęczna-Włodawa Lakeland (Eastern Poland). The results of this research show that the decline in population numbers of the studied species is associated with the changes that have taken place in their habitats since the 1950's. These changes manifest themselves in the species composition and structure of the phytocoenoses of which the species under investigation are components. In consequence, the intensive process of ecological succession can accelerate the rate of extinction of S. lapponum and S. myrtilloides within the area of the Łęczna-Włodawa Lakeland.
