This paper summarizes measurements of the radioactivity of soil and plant samples from the part of the Łęczna-Włodawa lake district, which is under a re-naturalization project, in Lublin and Chełm provinces (Eastern Poland). The aim of the studies was to determine the concentrations of particular radionuclides in the soils and plants of this district. The total radioactivity is reported as well as the contribution of artificial radionuclides (Cs-134, C-137) whose presence is due to radioactive fall-out. The total radioactivity of the soil samples ranges from 100-900 Bq/kg, and that of plant samples from 100—1300 Bq/kg. Contamination by radiocesium depends on the migration of water.

The studies carried out in the years 2004-2005 and in 2009 were aimed at identifying the functioning conditions of a boreal plant relict, Salix lapponum, in its stands under anthropopressure in the Łęczna-Włodawa Lakeland. The study results confirmed that the number of S. lapponum stands on Lake Miejskie and on Cow Marsh and its population size had significantly decreased as well as the population condition had deteriorated during the last 50 years. Based on the results of an analysis of environmental (biocenotic and abiotic) factors it was found that changes in habitat conditions in its stands were the main threat for downy willow. Another cause of population decline and the deteriorated condition of downy willow individuals may be the habitat isolation. The observed intraspecific phenomena, i.e. the lack of flowering in individuals and the lack of downy willow seedlings could be the reason for insufficient reproduction efficiency, ipso facto, the weaker adaptation of individuals to changes in habitat condition. Therefore, it seems that it is necessary to pursue active species conservation and protection which should primarily involve population reconstruction – restitution.

This paper presents the results of a pilot field study, conducted in July 2007, designed to make fl oristic evaluation of the peat bog area adjacent to the western shore of Lake Bikcze (Łęczyńsko-Włodawskie Lakeland). The main aim of the study was to confi rm the occurrence of populations of rare and legally protected plant species in this area and to identify, on a preliminary basis, habitat conditions in their stands. The occurrence of populations of the following strictly protected plant species: Betula humilis, Salix lapponum, Salix myrtilloides, Carex limosa, Drosera intermedia, Drosera rotundifolia, Dactylorhiza incarnata; and partially protected species: Menyanthes trifoliata, has been confi rmed in the studied peat bog. Both an investigation of abiotic factors, conducted in situ, and an analysis of the species composition of the flora in terms of habitat preferences of particular groups of taxa have shown that the described rare plant species find suitable conditions for their growth and development in the studied peat bog.

In the period 2007-2009, floristic, habitat and physico- chemical analysis was made of the hydraulically improved surrounding ditch of Lake Bikcze in the Łęczna-Włodawa Lakeland. Hemicryptophytes, with a large proportion of geophytes as well as hydrophytes and helophytes, were the main component of the flora of the studied section of the transformed Piwonia River channel. In terms of historical-geographical classification, spontaneophytes were predominant, and apophytes among them, whereas anthropophytes were poorly represented, which was confirmed by the correspondingly high values of the synanthropization and apophytization indices (> 50%) as well as the low value of the anthropophytization index (approx. 2%). In the aspect of the range of occurrence, Euro-Siberian and cosmopolitan species were predominant, which are classified in terms of the indicator values as hygrophilous plants, neutral to continentality, living in moderately cool or moderately warm climatic conditions, characterized by a wide range of tolerance to the trophic state index and to soil acidity. An analysis of the values of the basic physico-chemical factors of the stagnant water in the surrounding ditch showed variations in the value of pH, electrolytic conductivity and the value of the concentration of organic and ammonium nitrogen as well as of organic phosphorus and phosphates. In spite of the anthropogenic nature of the studied watercourse, the qualitative and quantitative proportions of the flora species indicated the natural state of the flora based on the native vegetation, characteristic of the study area.

During studies of phytoplankton in Sumin Lake (Łęczna-Włodawa Lakeland), conducted from May till September 2001 and 2002, 15 taxa of the genus Pediastrum (Hydrodictyaceae, Sphaeropleales) were found. Among them there were common species as Pediastrum boryanum, P. duplex, P. tetras and P. simplex, but also rare species as P. integrum or P. kawraiskyi. An especially interesting species was P. orientale, the taxon that until now has not been noted in phytoplankton of Polish water bodies. The paper gives descriptions of the genus Pediastrum coenobia and physico-chemical conditions of the habitat. The original documentation of Pediastrum taxa is added.
