In Sweden lot of state owned forests or earlier mining districts or districts of ironworks have been afforested during the last decade. The amount of afforested areas sinks from south to north. Afforestation has taken place also in privately owned forests.
The article discusses the common economic questions related to afforestation work and the biological viewpoints related to it. The best cultivation methods are presented for several common forest types, such as herb-rich forest types, moss-grown forests types, swampy forests with heavy raw humus and barren pine forest sites (lichen type).
The volume 34 of Acta Forestalia Fennica is a jubileum publication of professor Aimo Kaarlo Cajander.
