Assessing the human impact on the naturalness and vegetation characteristics of protected areas is one of the key issues when designing forest conservation networks in Fennoscandia. We studied the small-scale, detailed relationship between forest utilization history and the current availability of dead woody material in a protected old-growth forest area in North Karelia, eastern Finland. From the study area of 32.4 ha, all the stumps (diameter ≥ 5 cm and height < 1.3 m, classified as natural, man-made and of undetermined origin) were measured using 25 x 25 m sub-plots. Standing and fallen dead trees (dbh ≥ 5 cm) were measured on 50 x 50 m plots in an area of 7.8 ha. The average number of stumps was 130 per ha, and over half of the stumps were classified as man-made. However, the historical documents since the 1910s showed no logging in the area: some of the largest man-made stumps probably originated from an earlier time, but most of those stumps were made considerably later. The variation in the total number of stumps (per ha) was great (range 0–560/ha, 0–16 m2/ha), with no clear clustering in space. However, clustering of man-made stumps was detected. The average volume of pooled standing and fallen trees was 84 m3/ha, with a range of 37–146 m3/ha. The other noticeable man-made disturbance besides logging was notching of aspens, which has a scatteredly significant influence on the amount of dead trees. In conclusion, the protected old-growth forest was not as a whole in a natural state but showed different degrees of human impact from virtually untouched patches to quite heavily managed patches. The results suggest that the number of man-made stumps may be a relatively quick and easy method of assessing the naturalness of woody biomass structure in the Fennoscandian boreal forests.

English title: The relation of the productive capacity of forests, their current production and wood utilization.

Annual variations in wood utilization makes it complicated to estimate the balance between wood utilization and wood production of forests. According to the article, the balance is unsustainable especially in the private forests in the southern part of Finland. The annual wood utilization of the country was 37.3 million m3 in 1913, and the annual wood production 35.2 million m3, according to a report of a committee that was appointed to find methods to prevent overcutting. The committee suggested legislation to forbid forest devastation. Also the growth of the forests could be increased, if the forests are well managed, the article argues. To prove this, the potential wood production capacity is estimated for the municipalities of Viipuri, Mikkeli and Kuopio, and compared to the present wood production and wood utilization of the area.

English title: Trends in the forest management in Central Europe.

In the densely populated Central Europe, forestry has always had different functions than in Scandinavia or Canada. Today the increasing pressures on the environment and more numerous demands of the people have put emphasis on environmental management and the demands of recreation in forest management practiced in the area. This paper outlines the trends in the utilization of forests in Central Europe, and especially in the Federal Republic of Germany, due to these changing targets. The regulations concerning forestry in Baden-Würtenber, and the forest plan of the Bavarian state forests are used as an example to clarify the principals of forest management and planning.

English title: Utilization of forests in north Ostrobothnia and its effect on their condition.

The purpose of the present investigation was to study the extent of human interference with the forests of different epochs in the district of north Ostrobothnia in Northern Finland, and its effect on the condition of the forests.

The study revealed that the quantities of wood removed were not most detrimental to the condition of the forest; the regionally irregular loggings and the logging methods employed were the most harmful. The old forms of wood utilization, tar industry, shipbuilding, sawmill industry and timber exports, were characterized by timber selection. Public opinion considered it the only recognized cutting method long after the conditions had changed and silvicultural methods should have been used.

The spread and abandonment of selection cuttings are illustrated in the results of first National Forest Surveys in Finland. According to the first survey (1921–1924), nearly half of the loggings in the province of Oulu were based on selection, which spoiled and devastated 41% of the forests. In the 1930s one-fifth of the North Ostrobothnian forests were weakened by selection cuttings, in 1960s the figure was 6%. The article also summarises the extent of tar and pitch production, sawmill industry, shipbuilding and household wood consumption of wood in the area.

English title: Tar burning in Finland in the middle of the 18th century.

Tar was an important export article in Finland, then a part of Sweden, in the 18th century. For instance, in 1640 half of Finnish trade consisted of tar. In other countries, like Norway, Poland, Archangel in Russia, and North Sweden, burning of tar was minor compared to Finland. In Finland, tar was produced of young pine trees. Tar production concentrated in more remote locations of the country, where it would be too difficult and expensive to transport timber and wood products. The cheapest products, such as wood, boards and planks, were produced on a coastal zone at farthest 30 km from the coast. Tar was produced in the zone beyond the coastal district. The inland parts of Southern Finland were, however, hilly which made even the transport of tar difficult. Tar production ended by the middle of the 19th century when wooden ships were abandoned, and the value of forests and other wood products increased.

English title: A short account of the history of the forestry of the Jokioinen Estate.

The Jokioinen Estate was established in 1562 when king Erik XIV of Sweden granted a large area around Jokioinen in the southwest Finland to Klas Kristersson Horn. The estate had several landlords until it was acquired in 1872 by Jokkis Stock Company, and finally sold to the government in 1918. The forestry of the estate was influenced by complications concerning the ownership of the land. A part of the tenants of the estate had originally been independent and owned their farms, but some farms were so-called family-right-farms, which were inherited from father to son, but the farmer did not own the land. A third type of farmers were ordinary tenants, who were directly dependent on the landlord. Especially ambiguous was the family-right-farmers’ right to harvest timber from the forests. The Finnish government acquired the estate to solve the problems and gave the tenants right to buy their farms.

Until the 18th century most of the farmers in Jokioinen area practiced shifting cultivation. This method of farming influenced strongly the forests, and continued until the increased market price of timber made it unprofitable. The forests were also the source of fuel wood for both the farmers and the landlord. The estate had own saw-mill industry since the 18th century. In 1871 a trained forester was hired for the estate. When the government acquired the estate, it comprised 32,000 hectares of land. The state retained 7,000 hectares of the forests. They were managed by a trained forester and administrated under the Board of Agriculture.

English title: Ensuring preservation of forests on the coast of Gulf of Finland in the Karelian Isthmus.

Metsähallitus (Forest Service) commissioned a study about condition of forests on the coast of Gulf of Finland in the Karelian Isthmus. The study was made because of a growing concern on overcutting of the private forests in the area. Dominant tree species in the area is Scots pine (Pinus sylvestris L.). In fresh mineral soil sites Norway spruce (Picea abies (L.) H. Karst.) grows in mixed forest with pine or as pure stands. The forests are in average 50 to 70 years old. Younger or older stands are less frequent.

At the beginning of 18th century the local peasants sold plots for Russians, and a villa area was created along the coast. When Finland became independent, many of the properties changed owners. Timber harvesting of the forests increased and many small sawmills increased the demand of wood. Because of the cuttings, productivity of the forests decreases and danger for wind damage in the forests increases.

The author suggests that legislation created to prevent deforestation as well as counselling should be applied to improve forest management. In addition, a protective area should be formed in the Karelian Isthmus where forest preserving directives should be followed.

A summary in German is included in the PDF.
