Assessment of the rate of vegetation succession at abandoned stone quarries using dendrochronology
 Derková, Nikola ; Chuman, Tomáš (advisor) ; Šefrna, Luděk (referee)
Dendrochronology is a reliable method of determining the age of a stand. In this thesis, dendrochronology is used to assess rate of vegetation succession in abandoned granodiorite quarries. There were selected eight localities in the study area, each with several sites. At each site there were four - five optically oldest trees selected, from which cores were taken using increment borer. A total of 79 increment cores were analyzed. The obtained age of trees was compared with known age of abandonment and a sequence of aerial photographs, showing history of sites since abandonment. As the results show, tree vegetation is attached in the area after approx. 3 - 7 years from the end of disturbance. We observe continuous stand in the area after approx. 12 years from the end of disturbance.
