The repetition of the forest soil inventory provides the basis for representative forest soil monitoring throughout Switzerland. Through the connection to the sampling network of the National Forest Inventory, a variety of possibilities for the use and evaluation of the collected soil data are possible.

In the framework of ICP Forests, we sampled and analysed soil profiles on [...] occurring changes in soil properties and functions (project «Forest Soil Inventory»).

In the years 2021–2025, the forest soil survey of 1993 on the 8 x 8 km will be repeated. This grid does not cover all combinations of soil formation and environmental factors that potentially occur in Switzerland. This project evaluates the most efficient way to close these gaps.
This project delivers soil and site related information for Swiss forests which are based mainly on measured values: (i) response of tree species relating to direct and indirect environmental variables, (ii) quantitative characterisation of species' ecological niche and (iii) soil ecological indicator values for forest plant species.

The main goal of MoGLI is to project the potential distribution of the most common Swiss woody species across the entire forested area of Switzerland.
The aim of the project is to determine the biomass of individual trees more precisely using non-destructive measurement methods. Such estimates are central for the greenhouse gas inventory, Kyoto reporting and for the estimation of wood resources and bioenergy potentials.
