Data and applications for the forestry sector

Potential distribution of the most common woody plants in Swiss forests

Where do ecologically valuable or rare tree species, such as oaks or yews, grow? The Swiss Federal Institute for Forest, Snow and Landscape Research (WSL) has developed the first high-resolution online maps that can provide detailed answers to such questions for 56 woody species found in Swiss forests.

FORTE Future

Visualise long-term projections of Swiss forests with the FORTE Future app. Future distributions of habitat suitability and genetic mal-adaptation for various tree species are available.


Visualise the current condition of Swiss forests with the FORTE app. Filter data by tree species or by area through an intuitive user interface to assess heat and drought induced stress and the consequences for forest health.

Priority themes: Forest functions and climate change

Climate change affects the forest functions, forest health, the distribution of tree species and the forest as carbon sink. Recommendations for adapted forest management are being developed.
