Dendrogeomorphological analysis of mass movement dynamics in the Jezeří Chateau area
The object of this study is the dendrogeomorphological research of 35 severely tilted trees (Fagus sylvatica) in a natural hazard area around Jezeří Chateau in the Krušné Hory Mountains. The paper studies the dynamics of mass movement in a geologically and geomorphologically problematic area, where mining expanded high up onto the southeast-facing slopes of the Krušné Hory Mountains. Growth disturbances – eccentricities of annual rings and sudden growth changes – were examined and described for the period from 1900 to 2006. Significantly low mass movement “rates” can be observed during the 1940s and 1990s, high mass movement “rates” were identified during the first decade of the 1900s, the end of 1950s and during the 1970s.
