L.) has been sampled from 42 sites in northern Fennoscandia. The sampling sites are mostly small lakes in the timberline zone located between 68°30’ N and 70°00’ N and at elevations ranging from 75 m a.s.l. to 515 m a.s.l.

Growth Trends of Forests in Finland and North-Western Russia, of the area, close to the Arctic timber line. The forests in that region are especially suitable for trend studies due to strong reactions of tree growth to the environmental changes and lack of competition due to low stand density..In the North, both negative and positive trends have been found.

Studies on Growth Trends of Forests in Sweden and Norway,gun in 1923. Young stands generally indicate higher site indices than old stands at equal site conditions. For spruce, this rise of site index has been estimated at 0.05–0.11 m.year., with the highest value in the south.

Site indices, i.e. top height in 100-year-old stands, were estimated using site-index functions commonly applied in Sweden on two different occasions for each sample plot.
