To achieve a continuous and constant timber flow over a longer time period, the forest holding structure should be close to normal forest or regulated forest. Concept of normal forest is presented as the model of achieving the highest possible sustainable yield and hence also the best economic return. The article discusses the regulations on the management of a forest holding with the view on regulating the forest yield.
Felling need to be planned according to the forest site and tree species. The main tree species for silvicultural purposes are pine, spruce and birch. After the widely used controlled burning of forests the state of Finnish forests is mostly weak and far from the “normal forest”. Majority of forests are of young and there are lots of broadleaved forests. Because of the great variation of the forest sites and their productivity as well as the small size of holdings in Finland, the selection of forest management regime, mainly the felling style (clear cut or light selection) is also important. The idea of management plans is represented.
