The aim of the study was to collect the first complete statistics on pastures and grazing of cattle in Finland. The data was collected in connection with an investigation of wood utilization in 1937-1938. Overall trend in grazing is that forest pastures are being replaced with restricted forest pastures and those further with hay meadows. This development is proceeding in the whole country, and it is almost completed in Western Finland. Grazing will probably be transferred completely to cultivated lands in the coming decades. This is important question also for the forestry, because of the damage grazing causes for forest.
Forest pastures are, however, still very important in animal husbandry. They produce over 500 million forage units. It would require 400,000 ha of hay meadows to produce corresponding amount of fodder. To sustain the present number of cattle, a third of all arable land in Finland should be hay meadows. The main goal for development of pastural agriculture is improving the effectivity of grazing and productivity of the pastures.

The article presents the characteristics of different vegetation areas (meadows and peatlands) by their distinctive vegetation. The study area is by the Barents Sea and is the northernmost part of continental European Russia. Different sites are classified by plant communities and/or vegetation units.

The data has been collected from an old natural meadow in Sortavala, Karelia (on that time it was part of Finland). The vegetation on that meadow was very homogenous. All plants of the selected species (Trollius europaeus; Ranunculus auricomus; R. acer; Potentilla erecta; Alchemilla vulgaris; Geum rivale; Prunella vulgaris; Chrysanthemum leucanthemum; Polygonum viviparum) were collected from the sample plots with their roots. The seedlings were then ordered into age classes, and the shortest possible time before inflorescence was determined. To find out the germination time sowing trials were conducted.
The seedlings are very abundant in the youngest age classes and then the amount of plant individuals sinks quickly. The reasons for dying are e.g. insufficient amount of nutrients available and the lack of winter hardiness.
