Tree inventory and proposal of new trees along old carriage road in Kostelec nad Černými lesy
Novák, David ; Bažant, Václav (advisor) ; Vítámvás, Jan (referee)
Thesis is focused on the Carriage route at Kostelec nad Cernymi lesy as a historical and dendrological route from Kostelec to Cesky Brod. Content of this thesis is the inventory of historical and exotic trees along this route, furthermore there is contained offer, how to proper treat this trees and also, following sprout of trees to fill the alley. Thesis rates the condition of neighboring exotic cover of Metasequoia glyptostroboides, Phellodendron amurense, Juglans nigra and Carya cordiformis. During the inventory along the route, there was found in total 13 autochtonous and 13 allochtonous trees. At these individuals were find out information about the height, diameter growth at breast height, age, stability, health condition and also the physiological age. The result of this thesis is a list of recorded trees with theirs scores of physiological attributes, then the offer, how to proper treat this trees and following sprout of trees to fill the alley. All these information are transferred into map file in software GIS. Further thesis contains information of this historical route and archival maps.
Annual progress of radial increment of selected species in Arboretum FFWS in Kostelec nad Černými lesy
Chržová, Anna ; Bažant, Václav (advisor) ; Vítámvás, Jan (referee)
Abstract This thesis deals with the evaluation of the annual radial increment measured during the vegetation period 2014 and 2015 on three species of trees in the Arboretum of The Faculty of Forestry and Wood Sciences of the Czech University of Life Sciences Prague in Kostelec. Evaluation of the seasonal dynamics of radial increment of Abies grandis (Grand fir), Picea sitchensis (Sitka spruce) and Pseudotsuga menziesii (Douglas fir) on plot stands in the Arboretum in Kostelec was made by comparing the climate in the time period and the annual radial increment as it changed during the season. Annual radial increment of Abies grandis, Picea sitchensis and Pseudotsuga menziesii was detected by device EMS DRL26A. This device also subscribed information about the temperature during the growing season. Data was processed by software EMS Mini32 and exported to Microsoft Excel 2016. Information about the temperature, I determinated with using a meteorological station in the area of the Arboretum. Data fromdendrometer and weather station and their interdependence was evaluated using Microsoft Excel 2016 in the form of line charts. In 2014, I was dealing also phenological phases and the time of onset and end of it on observed species. Due to the extremely warm and dry year 2015, I had the opportunity to compare the responses of individual species at these climatic phenomens. In conclusion, the results are confronted with the literature searches and the discussion in this thesis, where I focused on the characteristics of measured trees and their application in European conditions
The tree inventory in gardens in Dobrissko region
Lexová, Jana ; Janeček, Vladimír (advisor) ; Vítámvás, Jan (referee)
Diplom work is describing woody composition of gardens in locality Dobříšsko. There were researched 50 gardens in this locality. Basic dandromatical parameters were found out (height, diameter of trunk, diameter of tree crown), the age of tree was estimated (determined), vitality and health condition of individual wood were rated and then care about greenery vas rated. Basic dandrometrical quantities were got with help of methodics of Agency for nature conservation and landscape Valuation of trees outside forests. The information about care about greenery, about tree felling, about signs of drought in 2015 were found out by questionnaire. Researched data were subdueded basic statistical analysis in program Microsoft Excel.
The structure of dispersed vegetation around Lovos near Litomerice
Kuperová, Zuzana ; Janeček, Vladimír (advisor) ; Vítámvás, Jan (referee)
This thesis mapped and analysed scattered vegetation in farmer landscape. The selected location was Litomerice area, especially the hill Lovos, what is an interesting place of its dendrology evolution in historical aspect. The goal of the thesis was to describe and analyse a vegetation diversity and dependency of it on the locations conditions. Also to map a trend in vegetation composition and structure. The composition of vegetation was strongly affected by post WWII era and a collectivization period. There was not described only the composition and structure of vegetation, but also a volume of the dead wood, visible stones above the land, connectivity, levels and water influence, means persistent water. It was found majority of fruit trees and isolated trees. The most successful vegetation was dog-rose (Rosa canina) and elderberry (Sambucus nigra). The mentioned vegetations are bushes and the big influence on the succession have the bird spreading and the seed resistance. The most successful trees were old world walnut (Juglans regia) and europian pear (Pyrus communis). The observation was compared with aerial photos in Marushka and aerial photos from 1953, which made sense of majority of fruit trees.
The structure of dispersed vegetation around the village Ostretin
Hloušková, Jana ; Janeček, Vladimír (advisor) ; Vítámvás, Jan (referee)
Scaterred vegetation is a significant element in a landscape which has many functions. The main functions are ecological, soil-protective, microclimatic, productive, medical, and hygienic. This thesis is focused on species composition in scaterred vegetation. The aims of this thesis were to find out the species composition and also the habitat characteristics during the past dendrologic research. Also, it was important to determine which factors affect the species composition. A study was held in September and October 2015 around a village Ostřetín in region of Pardubice. 19 tree species and 9 bush species altogether were found in 70 locations. To the largest group of bush species belong Sambucus nigra, Rosa sp., Crateagus sp. and Prunus spinosa. As for the trees species, the most numerous groups were Alnus glutinosa, Prunus domestica, Pinus sylvestris and Picea abies. All the collected data were statistically evaluated using generalized linear model. Neither water nor altitude influence were conclusive. On the other hand, factors as area, canopy, vertical stratification and presence of dead wood were significant meaning they affected the species composition. Comparison of similar studies shown that the species as Rosa sp. and Sambucus nigra are significantly dominant bush species in scaterred vegetation. On the contrary, frequency of tree species is different in many cases.
Evaluation of fast-growing poplar in Doubravice
Bezdeková, Jana ; Bažant, Václav (advisor) ; Vítámvás, Jan (referee)
This work is focused on fast-growing trees, particularly in the eastern part of the Czech Republic. The introduction explains some concepts, biomass, its distribution and ways of energy recovery and environmental aspects of planting fast-growing trees. Furthermore, this work analyses the present legislation regulating the business. The main part is to perform measurements on specific selected plantation in the eastern part of the Czech Republic specifically in the village Doubravice. The measured results are compared with the end results of other authors who have conducted similar research.
