Comparison of vegetation on ski slopes with artificial or natural snow in CHKO Bílé Karpaty and CHKO Beskydy
KOCKOVÁ, Jitka
Vegetation cover of 24 ski slopes both with artificial and natural snow was studied; on each slope 5 phytocenological relevés measuring 4 x 4 metres were taken. A method of direct gradient analysis (RDA) was used to detect differences in composition of phytocenological reléves on the ski slopes with natural or artificial snow. However, no impact of use of artificial snow on vegetation was identified. During the winter season of 2009 and of 2010 samples of artificial and natural snow were taken for chemical analyses. The chemical composition differed significantly; artificial snow contained more NO3-, SO42- and Ca2+ ions and its pH was more alkaline in comparison with natural snow.
