The Swedish National Forest Inventory

Updated 2017-10-16

This project was previously a part of the project: National Survey of Forest Soils and Vegetation.

The Swedish National Forest Inventory (NFI) has the task of describing the state and changes of Sweden's forests. The inventory gathers basic information on forests, forest stand conditions and vegetation. Regularly monitored variables are: forest state, injuries, growth, logging operations, new forest stand, and environmental assessment. There is a close collaboration between the NFI and the Swedish Forest Soil Inventory (SFSI).

This is not a National Implementation Plan (NIP) project
Comments and additional information:

Monitoring proceeds in five-year intervals. Forest state variables include list of tree species, wood dimension, maturity class, and tree age. The forest injuries variables are described by needle loss and tree injuries. The new forest stands are defined as an age of forest clearings and thicket stage. The environmental assessment includes an old growth forest, large trees and deciduous intermixtures, and coarse Woody debris reporting.
