Historical data from National Forest Inventory (NFI)


The Swedish NFI has collected data on the nation's forests since the 1920s. Our project makes older data available by transforming it from paper forms to digital format. We also work with analysis and harmonization of long time series to make the results easier to access.

The work is financed by the Swedish Research Council, Swedish University of Agricultural Sciences, Formas, the Kempe foundations, Nordic Forest Research Co-operation Committee, the Royal Swedish Academy of Agriculture and Forestry and the Swedish Public Employment Service.

The project is a part of the Forest programme within the Environmental Monitoring and Assessment at SLU.
