Influence of plant cover on spring water chemistry in the Silesian Beskid Mts
Katarzyna Krakowian , Stanisław Małek
AbstractChemical characteristics of mountain spring waters are very interesting due to their complexity. The present paper attempts to determine interactions between water chemistry and the plant cover over their water supply reservoirs.The study concerns springs located on the slopes of Skrzyczne in the Silesian Beskid Mountains. Samples were collected in 2009, 2011 and 2012 - in each year, in three session under different weather conditions. It was expected to find statistically significant differences in water chemistry between these 3 session and between the springs which are under the influence of different kinds of plant cover. Differences were also expected due to the geological bedrock structure (godula sandstone), which causes a shallow water cycle (Krause et. al. 2010); moreover, they are suggested in previous paper, concerning research on the same terrain conducted in 2004 (Astel et. al. 2008). The Ward grouping analysis, the Kruskall-Wallis test and the Dunn test resulted in the following findings : a) air pollution with nitrates influences spring water chemistry in the Silesian Beskid Mountains with the strongest impact during snowmelt; b) intensive rainfall causes increased leaching of nutrient cations and additionally SO42- and Cl-; c) the influence of the plant cover is the largest especially during snowmelt and the intesive precipitation period; d) springs situated in beech and mixed stands have increased values of:: conductivity, Na+ , K+ , Ca2+, Mg2+, NH4 + and Cl- , SO4 2- concentrations, whereas springs in bare areas, dieback areas and coniferous forest cultures show decreased values of:pH, conductivity, Na+ , K+ , Ca2+, Mg2+ and NO3 - , Cl- , SO4 2- concentrations; and springs found in spruce stands have decreased valuesof: pH, conductivity and Ca2+ concentration.
