Stillberg station (STILL)
Reference CryoNet Station Information

The research area Stillberg at the alpine treeline has been established in the 1950s in a collaboration between the WSL-sites Birmensdorf and Davos (“Gebirgsprogramm”). The original aim of this research program was to find appropriate methods for afforestations in potential avalanche starting zones near treeline. Since the year 1975, the research area Stillberg has been systematically planted with 92’000 trees (Larches, Stone pines, Mountain pines) and provides unique information about long term effect of different environmental factors for treeline trees. The experiences from the Stillberg have helped to afforestate high altitude sites more appropriate. During the last decades the Stillberg research area has also increasingly served as experimental basis for different experiments focusing on questions about climate change effects on treelines. Additionally it is an interesting station by being a steep (34deg) north face. The observer station is located next to the automatic weather station. It is one of very few station were snow profiles on a slope are collected at the same location over a winter. The information collected is important for both avalanche and ecological studies.
