Current condition and historical development of waterlogged meadows in the region of Říčany
 Horina, Lukáš ; Münzbergová, Zuzana (advisor) ; Kindlmann, Pavel (referee)
During a cooperation on a project of the orchid protection in the Říčany Ecocenter number of questions arose. Firstly it is a question of an identification of orchid meadows. Then finding main parameters of an environment, which influence the occurence of Dactylorhiza majalis. Consequently finding factors that influence the size of population of Dactylorhiza majalis. And eventually finding a suitable management for the orchid meadows. I was trying to find the answers mainly via a comparison of orchid and similar non orchid meadows. I was comparing species composition, local conditions and historical use of the site. I decided for the method of phytocenologic snaps and Ellenberg numbers for detection of the local conditions. Historical maps were used for finding the historical use. Data were processed by statistic analytical methods (PCA,RDA) When comparing orchid and non orchid meadows I found out that they differ conclusively in species composition and in number of species. I found plant species according to which it is possible to determine a potentional orchid location. Furthermore I found out that orchid and non orchid meadows differ in values of parameters of an environment. Consequently I found that these parameters are continentality, humidity and trophy of the site. Then I found out that humidity...
