The aim of the bachelor thesis was to determine the floristic composition of vascular plants and bryophytes, to record forest communities by phytocenological records and to analyze the functional and ecological traits of the recorded taxa in a selected area of the Zámutovské skaly Nature Reserve in the Slanské vrchy Mts. Within the studied area, we made two representative phytosociological relevés based on the method of the Zürich-Montpellier school. In order to analyze the functional and ecological traits of the recorded taxa, we used available databases and literature to compile data on life forms, life span, leaf duration, life strategies, link to the forest environment, ecological specialization index, affiliation to syntaxonomic units of plant communities, occurrence in elevational zones, hemeroby, substrate preference, and demands for temperature, light, moisture, nutrients, soil response, and continentality. In the studied area, we recorded a total of 135 taxa of vascular plants and 51 taxa of bryophytes, two of which (Sempervivum carpathicum subsp. heterophyllum and Woodsia ilvensis) belong to the vulnerable taxa of the flora of Slovakia. In terms of syntaxonomic classification, the relevés were included in the association Mercuriali perennis-Fraxinetum excelsioris and Aceri platanoides-Tilietum platyphylli and in terms of assignment to groups of forest types in the Tilieto-Aceretum 3rd vegetation altitudinal zone of the trophic-edaphic rank C and Carpineto-Aceretum 2nd altitudinal zone of the rank C, respectively. Based on the total species composition, the investigated area can be classified into boulder linden maple (Tilieto-Aceretum lower zone) and stony hornbeam maple (Carpineto-Aceretum higher zone). Based on the affiliation to the syntaxonomic units, the most numerous representation of vascular plants and bryophytes within the entire area of interest were diagnostic for the class Querceto-Fagetea, the order Fagetalia sylvaticae and the association Fagion sylvaticae. Despite the fact that only about a quarter of vascular plants and 40% of bryophytes are typical for closed forests, the results indicate a more stable and natural habitat as the area was dominated by perennial, generalist and tolerant species of natural habitats, and a relatively high percentage of specialists was also present. Indicative values for temperature showed predominance of vascular plants indicating mild heat, while a high percentage of bryophytes indicated cold to very cold situations, similarly, indices for light showed that vascular plants were mostly semi-light-loving, while semi-shade-loving bryophyte species predominated. The charts for continentality showed a prevalence of oceanic to suboceanic species of vascular plants and intermediate and subcontinental species of bryophytes. According to nutrient requirements and soil reaction of vascular plants, medium-rich to rich soil types with a slightly acidic to neutral reaction predominated, while in bryophytes, species of poorer and more acidic soils were more prevalent. In terms of soil moisture, vascular plant species of freshly moist to moist soils were dominant, while bryophytes indicated slightly drier soils. The relatively high incidence of recorded bryophytes on various substrates (bark of phanerophytes, rock, dead wood and soil) reflects the preservation and forest character of the environment with a high diversity of available micro-habitats. The presented thesis contributes to the knowledge of flora of vascular plants and bryophytes of the Zámutovské skaly Nature Reserve. The benefit of this work is also a more detailed assessment of environmental conditions through the functional and ecological traits of the recorded plant species and their comparison with data adapted to different floras of the European region.
