The close correlation between climatic fluctuation and forest growth near the tree‐line is discussed. Depending on climatic conditions, the opinions of foresters on the yield potential of the northernmost pine forests have varied greatly from time to time. In Finland the Zone of Protection‐Forests is defined by law (1922) and the Forest Research Institute has prepared practical instructions for the silvicultural management of the Protection‐Forests (1959). These instructions are rather conservative. Thus, radical measures, such as clear‐felling and artificial reforestation, are avoided whereas, in the first place, silvicultural thinnings and removal of over‐mature standards in younger stands are recommended. This kind of management allows the rational utilization of the yield capacity of the forests, without endangering their future existence. The scenic value and multiple use of these forests also are considered in the management instructions.
