The Swedish Forest Soil Inventory (SFSI) collects information about soil conditions and soil chemistry from c. 20000 objectively located plots across all of Sweden. All land use types except urban areas, cultivated land and the high mountains are included. One tenth of the sampling plots are re-visited each year.

SFSI provides background data for indicator-based monitoring of the Swedish environmental quality objective "Natural acidification only" (for more information see "Environmental Objectives Portal"). It also provides data for international
reporting from Sweden to the UNFCCC and the Kyoto protocol for the LULUCF sector, as well as for the reporting of critical loads for Swedish forestland, requested by the Convention of Long Range Transboundary Air Pollution (LRTAP). SFSI data is also used for research on forest soils and forest ecosystems.

There is a close operational collaboration between the SFSI and the Swedish National Forest Inventory (NFI) and the two inventories utilize the same permanent plots.

Under the name the National Survey of Forest Soils and Vegetation the first inventory was carried out during 1983-1987. The second inventory of the same plots was done during 1993-2002 and the third inventory during 2003-2012, when the name also changed the Swedish Forest Soil Inventory. The current inventory started in 2013 and will run until 2022.

Results from the SFSI (for the years 1983-2002) can be found on MarkInfo.

Facts:

The SFSI is part of the national environmental monitoring commissioned by the Swedish Environmental Protection Agency. The inventory is carried out by the Department of Soil and Environment at SLU and is part of the Environmental monitoring and assessment programme "Forest" at SLU.
