Vliv pastvy ovcí na travní porosty v Chráněné krajinné oblasti Beskydy

The aim of this thesis was to assess and evaluate the species composition of grazing stands in two localities. The aim was also to find out what species in the Beskydy protected landscape area (PLA) dominated, how the species composition of the stand changed with altitude, pedological and climatic conditions. As the quality of grassland, diversity indices changed, there were demonstrable differences between sites and affected grass grazing during the year. Phytosociological imagery using projective dominance was used to compare the species composition of the stand and the Zurich-Montpellier system was used to casify plant communities. For the evaluation of the species composition of the foot stands, the calculation of the mean nitrogen number, mean water number, grassland quality, McNaughton's dominance index, Hill's diversity index, Shannon diversity index, Pielou's equivalence index, qualitative similarity index and statistical evaluation were used. The locality Za Kopcem was dominated by Festuca rubra L. and Festuca pratensis Huds., Dactylis glomerata L. and Trifolium repens L. in the locality Hutisko. The species composition was influenced by environmental conditions, which was also proved by the quality of grassland. The locality Za Kopcem balanced the low to medium diversity index, the Hutisko locality reached a medium diversity index. There were statistically significant differences between sites. Extensive grazing has caused an increase in herbs and the optimal pasture load has increased the incidence of lower grasses
