Finland's first National Forest Inventory started in 1921. To date, eight inventories have been completed with the main objective of providing forest resource information for forestry planning at both a local and national level. The results of the inventories have played a central role in developing forestry and forest industries. A systematic sampling method covering the total land and inland water area is employed. In the first four inventories, sampling was based on transects running south-west to north-east through the country. Systematic cluster sampling has been employed in more recent inventories, with field work carried out as a continuous annual process. Today, an additional network of permanent sample plots produces large volumes of new data concerning the status of and changes in the forest ecosystem. Modern methods using satellite imagery have also made it possible to acquire better localized information and more reliable results for smaller areas.
