The Swiss Federal Institute for Forest, Snow and Landscape Research (WSL, German: Eidgenössische Forschungsanstalt für Wald, Schnee und Landschaft, French: Institut fédéral de recherches sur la forêt, la neige et le paysage) is a Swiss research institution, part of the Swiss Federal Institutes of Technology Domain.[2]
Its scope of research includes "...changes to the terrestrial environment, and the use and protection of natural habitats and cultural landscapes."[3]
It is headquartered in Birmensdorf, Zürich and maintains a large office in Davos, home of the WSL's Institute for Snow and Avalanche Research (SLF).[4] The SLF is responsible for producing a national avalanche bulletin twice daily during winter.[5][6]
From 1942 until 2019, the WSL owned and operated a research institute on the Weissfluhjoch mountain (2693 meters, 8835 ft) above Davos. It was mostly used to study avalanches.
