The first estimates on the forest resources of Finland were presented in the middle of the 1900th century. The first line survey was conducted in 1912 in Central Finland. In 1921-1923 a survey of the forests of the whole country was commenced. The method consisted in measurement of sample plots in conjunction with ocular estimation of all the stands within the range of the lines. The methods were further developed in the second National Forest Survey in 1936-1938, which payed special attention to the silvicultural condition of the forests, and the growth in the light of climatic variation. When 3.3 million ha of forests were ceded to the Soviet Union in the peace treaty of 1944, the results of the survey had to be recalculated. The next survey was conducted 1951-1953. In this survey, the recovery of stands on drained peatlands was studied. The results of the inventories show that forest resources of Finland had icreased since the 1936-1938 survey.

The first investigation of wood utilization in Finland was carried out in 1927, after the first National Forest Survey had provided information on the forest resources, and knowledge of the other side of the forest balance was desired. The most difficult part was to determine the domestic wood consumption of the rural population. This was accomplished by studying 1,337 sample farms. The second investigation was commenced in 1938, and third in 1954.

These two investigations have made it possible to determine the annual removal and annual growth, and by comparing these results, growth balance. A forest balance is an essential condition for judicious forestry.

The Acta Forestalia Fennica issue 61 was published in honour of professor Eino Saari’s 60th birthday.

English title: Expansion capacity of Finnish forest industries and the sufficiency of wood raw material.

The Finnish forest industries have doubled their use of wood raw material during the past two decades. The average annual overcut of 4.0 million m3 in 1960–64 has been turned into an average annual surplus of 2.7 million m3 in 1965–69. By 1974 industry’s requirements for domestic roundwood would increase by about 6.3 million m3, if all new capacity can be taken into full production. The MERA allowable cut, if realized, would leave a 1.5 million m3 annual surplus in the forest balance in 1974. Less intensive forestry programs would mean a 1.5 to 4.4 million m3 overcut in 1974.

English title: A proposal to introduce permanent statistics of wood consumption in Finland.

The Forest Research Institute made an investigation on the wood consumption in Finland in 1927. This work brought up a need to organize continuous collection of statistics of wood consumption. Three kinds of existing statistics can be used: statistics of wood consumption, statistic of the fellings, and statistics of transport of wood.

Statistics on wood consumption, such as the fuel used by the industry and State railways are collected annually. The fellings in state forests are published annually, and also the wood manufacturing companies publish statistics of their forests. Furthermore, all fellings on sale, and use of own wood in wood manufacturing industry have to be reported to the forestry committees. These statistics are published annually. Railroads and floating are the main means of long distance transport of wood. These statistics give additional information of wood consumption. Further studies are needed to combine and standardize the statistics collected from different sources.

Seppo Ervasti, Lauri Heikinheimo, Viljo Holopainen, Kullervo Kuusela, Gustaf Sirén. (1965). The development of Finland's forests in 1964-2000. Silva Fennica no. 117 article id 4724. https://doi.org/10.14214/sf.a14282

The Economic Council asked Heikinheimo, Holopainen and Kuusela to prepare a report on the development of Finland’s forest resources up to the beginning of the next century. The expansion of forest industry beyond the level foreseen in earlier forecasts, the large-scale removal and neglect of the basic improvements required have weakened the condition of the wood production to such an extent that extensive measures are needed to ensure the continuity of the supply of wood. The results of the calculations are formed in three separately analysed alternatives.

Alternative I: Realisation of the Teho programme and the removal corresponding to it. The development of the growing stock according to the programme would only permit a cut amounting to an annual drain of ca. 51 million m3 up to the year 2000. After that it would be possible gradually to increase the removal. This drain would not itself to utilise fully the already existing production capacity of the industry.

Alternative II: Consequences of the predicted removal if the Teho programme is realised as such. The wood utilization forecast based on the premises given to the team show that the annual drain will grow in 1964–1975 from 52 to 58 million m3, and thereafter by 0.5% annually. This would lead to over-cutting, and exhaust the present growing stock by the turn of the century. If annual total drain of ca. 58 million m3 would after 1975 be sufficient, exhaustion of the growing stock would be postponed for 4–5 years.

Alternative III. Teho programme expanded in conformity with the removal forecast. A new programme is proposed, which includes, among others, large scale fertilization of fully grown firm forest land at about the rate of 100,000 ha/year, intensified artificial regeneration, assurance of the supply of planting stock and seed, increase of forest drainage from the present 155,000 to 250,000 ha/year by 1970, site preparation of the cutting areas for artificial regeneration, increase of tending or seeding stands to 300,000 ha/year, replacement of fuelwood by other fuels, increase of wood import and new forest roads.

English title: Forest devastation, its causes and prevention in Sweden-Finland.

The earliest local records of lack of timber in Finland are from the 1600th century when Finland belonged to Sweden. The causes vary from burning of tar and shifting cultivation to local factories using fuel wood. Best preserved were forests in Lapland and Kainuu in Northern Finland and those parts of Karelia where shifting cultivation was not practiced. Especially harmful was shifting cultivation, because it made it impossible to grow valuable timber. The state did not intervene in the use of forests until it itself began to need more wood. Shipbuilding was the first cause to limit the use of wood, especially need of mast trees of pine and oak. Also the use of timber by private sawmills began to raise general concern in the 16th century. They influenced the decrease of forests in the 1800th century, due to the limited wood procurement areas and selection felling of timber trees. The establishment of sawmills became regulated in 1700th century. Collective forest ownership by the farms was seen at the time one of the reasons to forest devastation. In 1654 the state of Sweden forbade the burning of mast or in timber forests. Mining industry needed much fuel wood, and shifting cultivation was forbidden near the mines in 1734. Regulations and instructions were also on given on use of wood, for instance, in building, in fences, leaf fodder, fuel wood and tar burning.

Despite of many efforts, the government of Sweden could not prevent devastation of forests in Finland. The many wars of the state hindered economic growth, the regulations were sporadic and often difficult to apply, there was little supervision, the understanding of forestry was poor, and the remote Finland was often neglected in Sweden.

English title: Improving the productivity of forestry in Finland.

The article is a joint study of the Forest Research Institute, the Forest Association and the Society of Forestry (now Finnish Society of Forest Science) on means to increase the productivity of forestry in Finland.

The study identifies five ways to improve the productivity of forestry in the country. First, the yield of forests should be increased by draining peatlands, reforestating understocked forests, changing tree species, if they are unsuitable for the site, increasing improvement fellings and enhancing regeneration in the cutting areas. Second, the utilization and trade of small-diameter timber should be developed. Third, export of wood should be promoted, while the use of wood as fuel instead of imported fuels should be increased. Fourth, the export of Finnish wood products should be secured, for instance, by reducing manufacturing costs and developing production methods in the industry. Fifth, both the elementary and higher education of forestry should be developed further.
