Influence of mountain farming termination on forest stands in the east part of the Krkonoše Mts.
Mach, Dominik ; Treml, Václav (advisor) ; Romportl, Dušan (referee)
This thesis focuses on the evaluation of the impact of abandonment of agricultural land on forest stands in the eastern part of the Krkonoše Mountains. The aim of this thesis is to reconstruct the evolution of the forest response to gradual termination of mountain farming. Specifically, I analysed the age structure of Norway spruce (Picea abies) and described the dynamics of secondary forest succession in meadow enclaves around huts. Three main research methods helped meeting the above-mentioned objectives of the thesis. The first is the analysis of old maps. The second is segmentation and supervised classification of aerial photographs. The last is dendrochronological research of the age structures of Norway spruce. Research showed the expansion of forest stands into treeless grassland enclaves. The main driving force behind this process of secondary succession has been the gradual decline of mountain farming. After the end of mountain farming in the middle of the 20th century,the dynamics of forest succession in meadow enclaves increased significantly, with the highest rate of succession in the following 20 years. Forest succession took place mainly along the edges of meadow enclaves. Inside the meadow enclaves, trees were mostly established along streams. The most significant factor that...

The memories of witnesses from eastern Giant Mountains
Lindrová, Tereza ; Jindra, Matouš (advisor) ; Suk, Aleš (referee)
Title: Memories of whithesses from the east of the Giant mountains Objectives: The aim of the work is to summarize historical events and social changes connected with the era from the beginning of colonization of the east of the Giant mountains to the second half of 1940s through utterance of regional natives compared to thematic literature. Methods: To gain data for this thesis regarding utterance of contemporary witnesses I used largely publications Krkonošští rodáci vzpomínají 1, 2 a 3, further a magazine Krkonoše-Jizerské hory, a website Paměť národa - Sudetské osudy (Antikomplex) and a method of semi- structured interview with one witness. I focused especially on German- speaking natives born in 1920s and 1930s from the east of the Giant mountains, largely from villages Horní Maršov and Velká Úpa and surroundings, occasionally supplemented by compatriots from the middle of the Giant mountains. It was 17 withesses in total - 8 women and 9 men. Afterwards I made a comparation of sources mentioned above with prefessional literature and populary educational literature and websites, which have a relation to the region and to period, historical and social events. Conclusion: The thesis introduced key moments of life stories of predominantly German-speaking withesses from the east of the Giant...

Response of forest succession to agricultural land-abandonment in the Giant Mountains
Dobíhal, Michal ; Treml, Václav (advisor) ; Chuman, Tomáš (referee)
Response of forest succession to agricultural land-abandonment in the Giant Mountains ABSTRACT: Since the end of the 19th century, there is undergoing process of land-abandonment of mountain meadows and pastures in most of the European mountains, including the Giant Mountains. Mountain agriculture in the Giant Mountains was terminated no later than before World War II. Abandoned meadows were then subjected to secondary forest succession. The question is, how fast was this succession and how was its dynamics. My research was focused on 4 areas of interest, located in the vicinity of former mountain huts. Methods applied included the analysis of historical maps and aerial photographs and dendrochronological research of age structure of Norway spruce (Picea abies) stands. The aim of this thesis was to find out the extent of mountain agriculture near the huts and the dynamics of forest succession following land abandonment. Main peaks of seedlings establishment were observed in a very short time (10 - 20 years) following termination of mountain agriculture and in most cases these peaks were further followed by one or two more weaker peaks in the later periods. These peaks became evident in the change maps of forest development with approximately 20 years delay. Forest succession was moving gradually from the...
