Abstract: [cze] [eng]
Práce zkoumá vliv managementu (kosení, kosení+narušování+odstranění stařiny) na tři vybrané druhy mechorostů rašelinných luk. Manipulativní experiment s různými typy zásahu byl založen na 16ti lokalitách na Šumavě, v Předšumaví a na Českomoravské vrchovině. Zásahy byly prováděny po dobu 3 let(2010-2012). Také bylo měřeno pH, konduktivita a výška hladiny spodní vody na lokalitách. Tři roky provádění managementu stačily na to, aby se projevila pozitivní reakce druhů Breidleria pratensis a Tomentypnum nitens na některé zásahy. Změna pokryvnosti druhu Sphagnum warnstorfii nevykazoval pozitivní ani negativní reakci na zavedení managementu. Effects of different types of management (control, mown, mown + disturbed (gaps) + litter removed) on three moss species of fen meadows were studied. Experimental plots were established at sixteen sites in the Bohemian Forest, in the foothills of the Bohemian Forest and in Českomoravská vrchovina. Relevés and micromaps of bryophytes in the plots 0.5 × 0.5m were sampled at the beginning of the experiment during the summer season of 2010 and then after 3 seasons (during the summer season of 2012) of performing management. The age of the abandoned meadows was also determined and values of pH, conductivity and height of water level of each plot were measured. Positive influences of both types of management on the cover of Tomentypnum nitens and of management with creating gaps and remowing of litter on the cover of Breidleria pratensis were significant. Effect of management on the Sphagnum warnstorfii was significant only when processes of remaining on already occupied places and the expansion to new places were tested separately. Enviromental values did not significantly influence the change of cover of any species between 2010 and 2012. In conclusion, it is clear that diverse management with reasonable use of these practices (mowing, creation of gaps, litter removal) is desirable for maintaining of vital and diverse bryophyte layer.
