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 aim of the study was to determine the effect of grazing of the cutting areas to the ground vegetation and regeneration of spruce. The cutting areas could be divided into two kinds of areas based on the vegetation. Hillocks were drier and poorer than other parts of the cutting areas. Their vegetation did suffer less from grazing than the other parts of the cutting areas. The shade-loving plant species decreased, but as the poorer sites have less edible plants, cattle caused less damage than in the better sites. The even spaces between the hillocks had both positive and negative changes. Cattle transport seeds, tile and fertilize the soil, promote paludification, and decrease competition by the primary species like large grasses. This is beneficial to new species. Grazing is directed to large grass species like Calamagrostis. Those species that cattle reject, become more abundant. Stamping damages especially shallow rooted species and perennial species, like Norway spruce (Picea abies (L.) H. Karst.). Larger tree seedlings may get injuries in the stem.
