Tree-ring analysis is one of the most suitable methods for studying processes in landscape dynamics. In southern Switzerland these dynamics are extremely varied and rapid, which makes the use of dendrochronological and dendroecological methods particularly interesting. In 2003 the Sottostazione Sud delle Alpi of the WSL decided to enlarge its field of activities, making dendrochronology one of their core method of research. First studies are underway and possible applications are presented as case studies in this contribution.
