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.
Germination of selected species of Orchidaceae in the restored meadows in the Protected Area Bílé Karpaty.
SUCHÁČEK, Pavel
The aim of this thesis was to examine the germination of eight orchid species (Anacamptis pyramidalis, Gymnadenia conopsea subsp. conopsea, Platanthera bifolia, Neottia ovata, Traunsteinera globosa, Orchis mascula subsp. speciosa, Orchis ustulata subsp. aestivalis, Orchis militaris) on restored meadows of various ages in the southwest of the White Carpathians protected landscape area. During the evaluation, it was discovered that two species (A. pyramidalis and G. conopsea) had better germination than other species which germinated insufficiently (P. bifolia and O. militaris) or they didn't germinate at all (N. ovata, T. globosa, O. mascula, O. ustulata). Also the area around the restored meadows was mapped because of the potential orchid seed source for the research area.
Tvorba regionální semenné směsi pro obnovu luk
ZO ČSOP 58/6 Bílé Karpaty, Veselí nad Moravou ; Jongepierová, Ivana
Příprava regionální bělokarpatské směsi pro různé typy stanovišť a metodiky výsevu. Dřív vyseté plochy byly sledovány po stránce botanické i pedologické. Proběhlo pěstování rostlin v matečných porostech.
