Výskyt a hodnocení zdravotního stavu hlavních edifikátorů lesních porostů v oblasti Přírodní lesní oblasti č.16 Českomoravská vrchovina
 Krajíčková, Dominika
In 2021, the representation of European beech (Fagus sylvatica) in the Czech Republic was 9.3 %, of maples 1.6 % and oaks 7.6 %. These values are slowly increasing, and the representation of European beech has increased by 3.3 % of the total area of arable land over the last five years (Zelená zpráva 2021). This work discusses the life manifestations of European beech (Fagus sylvatica), Norway maple (Acer platanoides), Sycamore maple (Acer pseudoplatanus) and Pedunculate oak (Quercus robur) in selected small protected areas in the Natural Forest Area No. 16 of the Czech-Moravian Highlands. The aim of this work is to evaluate the life manifestations of the above-mentioned tree species. Three small protected areas were selected, of which two localities are located in the 5th forest vegetation tier and one partially in the 5th and 4th forest vegetation tier, and endometrial measurements were performed here. The result was a comparison of the obtained data between individual sets of forest types and individual tree species on the set of forest types 5J. The diameter of the trunk and the height of the beech crown deployment were lower at 5K. The Norway maple reached smaller thicknesses at 5J compared to the other trees, on the contrary, the Sycamore maple and Pedunculate oak reached greater heights.

Výskyt a ekologické projevy javoru klenu (Acer pseudoplatanus) a javoru mléče (Acer platanoides) na Lesnickém úseku Jelence Školního lesního podniku Masarykův les Křtiny
 Ždánský, Aleš
The thesis maps the occurence of sycamore and norway maple in area of the forest ecosystems sized 500 ha, which falls into the administration of Školní lesní podnik Masarykův les Křtiny, Polesí Bílovice nad Svitavou, Forestry section Jelence. The both maple species have been scattered in all of the four forest altitudinal zones and in the all of the five ecological tiers. norway maple has appeared mostly in the 1st. forest altitudinal zone and in the ecological tier enriched by humus. The largest number of sycamore has been in the 4th. forest altitudal zone and in the ecological tier enriched by water. The both maple species have been living in the most forest types of the defined location. The result is map data in ArcMap application in ArcGIS system. Both norway maple and sycamore have been found to resist biotic and abiotic harmful factors. Due to its resistence and great ecological amplitude, both maple species can be described as suitable for wide use in forestry in a wide range of natural conditions. As a source of reproductive material for Dyk‘s forest nursery of Školní lesní podnik Masarykův les Křtiny was designed 12 exceptionally high quality norway maple and 4 maple sycamores specimens as parents of families.
