Correlation analysis among the distribution of forest vegetation zones, selected climatological parameters and actual vegetation status in Hostýn-Vsetín Mountains subregion of natural forest region 41

Hostýnské mountains are part of the most frequently visited forests in Moravia. Whether because of the numerous cottage and recreational areas with abundant occurrence of fungi, these forests were subject to great anthropogenic influence since its origin. Therefore, it was created on the territory of several protected areas and nature reserves, which were designed to preserve the natural vegetation potential of local vegetation and protection of rare species of local phytomass and zoomass. The goal of this thesis is the verification of the respective forest vegetation zones of the investigated plots, which had been historically assigned in several respects. In the past, namely the allocation of forest vegetation zone was entirely an empirical matter, which scientists have not been able to verify the correctness of his judgment by means of statistical analysis, as is the case nowadays. The plots were therefore selected to characterize best the local conditions, whether in terms of species composition of vegetation or climatic conditions. On the 20 selected plots there were collected data within individual tree layers (based on Kraft-Zlatník scale), species composition and level of development of individual trees by circuits measured at breast height and height measurements according to average individuals. As additional data for the overall evaluation were used climatological maps using GIS software creating a mosaics from which it can be acknowledged how much of the forest stands is affected by abiotic factors such as the length of the snow or the average air temperature. The data assembling the complete image of the plot characteristics were subsequently analysed by regression and multivariete statistical analysis. The obtained results show the context between the actual stage of the forest stands and the used climatic parameters. I believe that this work could be a model for those who do not rely on empiricallly-derived forestry maps and admit that the overall climate in our country is changing and evolving. It is therefore important to consider these causes not only for the purposes of forest management, but also for the protection of existing vegetation.
