The Swiss Federal Institute for Forest, Snow and Landscape Research (WSL) investigates changes to the terrestrial environment, and the use and protection of natural habitats and cultural landscapes. It monitors the condition and progress of landscape, forests, biodiversity, natural hazards and snow and ice, and develops sustainable solutions for socially relevant problems – in collaboration with its partners from academia and society.

Of the 500 or more employees in Birmensdorf, Davos, Lausanne, Cadenazzo and Sitten, almost half are scientists and more than 60 are doctoral students. The work force also includes about 150 technical staff and 50 administrative staff, 15 trainees, and apprentices. About a quarter of the employees are working at the WSL Institute for Snow and Avalanche Research SLF in Davos.

The SwissForestLab initiated by WSL is a network of researchers from various institutions and their test sites and facilities. Through the intensive use of synergies in Swiss forestry research, it promotes joint research work in order to gain a deeper understanding of the functioning, resilience and adaptability of the woodland ecosystem. It also increases the national and international visibility of Swiss forestry research.
