 Rozsíval, Jan
The content of my thesis summarizes the existing knowledge about the growth manifestations of sycamore maple (Acer pseudoplatanus L.) and norway maple (Acer platanoides L.). In the area of Loučná nad Desnou, it maps growth manifestations, habitat and dendrometric characteristics in the range of the 3rd – 8th forest vegetation tiers. Norway maple in the spectrum of the 3rd, 4th and 6th forest vegetation tier. Based on the field survey, an assessment of the health condition and the limits of occurrence of trees of interest was prepared at the level of the spectrum of represented forest vegetation tiers. The analysis of the data shows a wide representation of sycamore maple (Acer pseudoplatanus L.) in the interval of 3rd – 8th FVT, there is production and ecological optimum of the mentioned tree species is in the range of 4th – 6th FVT. At the sites of these FVT reaches the highest heights and volume production. The representation of norway maple (Acer platanoides L.) was demonstrated in the 3rd, 4th and 6th FVT, but it is minimally represented in the examined area in compare with the first tree species. From the point of view of the influence of abiotic and biotic factors, it was found that the examined tree species are affected by these factors only sporadically. The thesis also includes a draft framework directive for management for nutrient habitats at higher altitudes and an analysis of prices on the market for sycamore maple (Acer pseudoplatanus L.) in Europe.
