The study is based chiefly on statistics of forest fires in the state forests in 1911-1921, published in the annual reports of Board of Forests (now Metsähallitus, Forest Service). Forest fires burned 37,200 hectares of forests in the state forests in 1911-1921. In Southern Finland the number of fires was 795 and in the Northern Finland 610. The frequency of forest fires is higher in south because of the denser population in the area. The average forest fire ranged 118 hectares in Southern Finland and 39 hectares in the north. Fires broke out most often because of careless use of fire. Weather conditions and the type of the forests influenced the risk of fire. In the north, risk for forest fire is lower because of the high proportion of peatlands. Only 14% of the fires burn the trees of the stand. In Southern Finland 50% of the fires and in Northern Finland 42% of the fires damage only part of the stand. Rest of the fires were surface fires that do not burn the trees. The value of damages by forest fires in the state forests in 1901-1922 was annually in average 139,400 Finnish marks.
