The paper discusses the principles of forest management in the state forests of Finland, and the contradictions in choosing between the different land uses. These principles of the forest management are sustainable use of natural resources, economic and effective management, and taking in account nature conservation, protection of environment, recreation services and employment issues in all activities of the Forest Service. Even regional policy affects the management planning in the state forests.

Abstract | View details | Full text in PDF | Author Info

Forests have been economically important for Finnish private forest owners at all times, but the use of forests has changed markedly since 1920s, when forests were mainly used for collecting household timber, and the cuttings were often exploitative because of the farmer’s need for money. The present situation is totally different. Need for household timber is marginally small, and private forestry produces mainly timber for sale. The sales of timber have increased, but due to better forest management the growing stock in the private forests has increased. The article discusses how the changes in values of forest owners has and will affect the stage of private forestry.

Abstract | View details | Full text in PDF | Author Info

The paper discusses how the general trend towards increasing growth and productivity in the European societies is expressed also in forestry. It is reflected, for instance, in the increasing production and productivity of forest industries. Technological progress and call for economic growth require great flexibility from all resources. These pressures for effectiveness and production also concern Finnish forestry and forest management. Industrialization, urbanization and development of forestry have increased the pressure to use forests in recreation, preserving human environment and nature conservation in addition to production of timber. Through the development the definition of sustainability has become wider.

Abstract | View details | Full text in PDF | Author Info

The results of regenerating 54 and 36–38-year old strip cuttings were surveyed in the Kivalo Research Forest (N 66°20’, E 26°40’). 15 measurement plots were placed on each strip. The most common forest type was Hylocomnium-Myrtillus type. Regeneration of the strips proved to be slow. Most of the spruces growing on the strips probably originated from the time before the cutting. The average number of stems was 1,155 per ha, of which one third consisted of broadleaved trees. The average volume increment of stem wood after cutting had been about 1 m3/ha/yr, but it was increasing at the time of the inventory. Both the reforestation of the strips and the development of the emergent stands were dependent on elevation and site fertility. Site fertility was indicated by the abundance of Vaccinium myrtillus.

Abstract | View details | Full text in PDF | Author Info

The area of stands studied by line plot survey was 594 ha. On the basis of the length of the inventory line the estimated proportion of harvesting strips was 14% and that of ditch openings 6% of the area. The calculated strip road spacing was 29 m. The option of the minimum diameter made it difficult to use the number of stems as criterion for thinning intensity. Thinning intensity evaluated according to the basal area had been stronger than recommended with low values of dominant height and milder with high values. The estimated removal according to stumps was 38 m3/ha on the average between the strips. The real removal has, however, been larger than that, as the strip road openings are made in connection with the first thinning.

Abstract | View details | Full text in PDF | Author Info

Forstästhetik is a programme for forest management, resembling an art manifesto. Forest managers are programme executors. Forest aesthetics is forest investigation from the point of view of beauty. In the case of managed forests, it is possible to ask, what is the manager’s programme and his skill to achieve personal solutions. In forests, the functioning and sustainability of the ecosystem are basic principles affecting all other values. On this basis it is possible to evaluate the competence of taste systems and the logic of their application.

The paper is based on a lecture given in the seminar ‘The forest as a Finnish cultural entity’, held in Helsinki in 1986. The PDF includes a summary in English.

Abstract | View details | Full text in PDF | Author Info

Young Norway spruce (Picea abies (L.) H. Karst.) are susceptible to early summer frost damage. Birch (Betula pubescens Ehrh.) naturally colonize rich or fairly rich drained peatlands after clear cutting, and can provide protection for developing seedlings. The report describes the development of spruce stands after various types of handing of the birch nurse crops.

Different proportions of birch and spruces did not have any influence on the spruce stand production. In cases where the nurse crop stand is removed when the spruce stand age was 20 years and height 4 m the spruce suffered badly but recovered with time, reaching the spruce stand growing under a nurse stand within the next 20 years. The height growth of spruce depends on the density of the nurse stand, especially on fertile sites. The development of diameter growth also depends on the density of the nurse trees. Removal of the nurse stand in spruce stands on the sites concerned should be done when the spruce stand is 20 years old and at the height of 4 m.

Abstract | View details | Full text in PDF | Author Info

This article reviews experiments and practical experience of forest management by the selection system in Finland. In an experiment of 25-year duration the annual growth of uneven-aged Norway spruce (Picea abies (L.) H. Karst.) stands was only about 50% of the average annual yield of even-aged stands in normal rotation on the same site.

In Finland the selection system is applicable under exceptional conditions only, viz. In intensively managed park stands and, on the other hand, on very marginal sites, e.g. on peat bogs and mountains near the tree-line. Even normal silviculture, however, may include cuttings which somewhat resemble selection system, e.g. removal of standards or restoration of mismanaged forests.

Abstract | View details | Full text in PDF | Author Info

A literature survey based on Nordic literature deals with the biology, use, harvesting and economy of birch (Betula sp.). According to the results, the easily quantified hard facts are against cultivation of birch: lower growth, poorer production of valuable assortments, lower price of pulp, higher planting costs, and higher harvesting and transport costs than for conifers. The soft facts, which may be true, are not easily measured or their importance evaluated: the possible improvement of soil, decreasing risk of insect and fungi attacks, shelter against frost etc. Due to the differences in the nature of the facts the discussion of cultivation of birch will probably continue.

The landscape preferences and attitudes of inhabitants of Puolanka, north-eastern Finland, to the effects of silvicultural practice on the forest landscape were studied by a postal inquiry. The effect of silvicultural practice on the forest landscape was mainly negative. Birch (Betula sp.) stands and mixed coniferous and deciduous tree species were the most preferred by the Puolanka inhabitants. The landscape preferences were related to socio-economic background of the inhabitants. The quality of the living environment also influenced the preferences, since uncommon features in the living environment were favoured most.

The part played by research work in guiding the management and utilization of Lapland’s forests is examined in this publication. The review has been written to mark the 70th anniversary of the Finnish Forestry Society (now the Finnish Society of Forest Science).

The climate in Lapland is very severe and, owing to the lack of experience abroad, forestry has been forced to follow the guidelines set by domestic research activity in Finland. Research work was very active in Lapland the 1910’s, 1920’s and 1950’s, and the main outlines for forestry utilisation were soon established. In the 1950’s, there was a strong trend prevailing to develop forestry, with the result that a change took place in favour of clear-cutting. The cool climate period in the 1960’s caused considerable damage to young plantations. In order to find means to rectifying the situation and to devise new guidelines for forest management, The Finnish Forest Research Institute established a number of research stations in Lapland.

Research activity has had a pronounced effect on the management and utilization of forests in Lapland. Present-day problems have been caused more by the international situation than by difficulties in the management of forests in Lapland.

Pair numbers of breeding land birds were estimated from line transects data collected in Finland in 1936–76. The changes observed in the bird populations are in this paper compared with data obtained in the Finnish forest inventories, particularly made in 1951–53 and 1971–76. It is concluded that modern forestry has considerable impact on the breeding bird fauna. In general, more species have increased than decreased due to changes in the forests. Areas affected by forestry are more favourable habitats for many species than natural forests, but, on the other hand, there are certain species which are greatly harmed by the effects of modern forestry.

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.

The purpose of this study was to gain an insight into research problems and themes in multiple use of forests from a practical viewpoint. An inquiry concerning multiple use problems was sent to 597 organizations whose work related to multiple use of forests. Replies yielded 1,857 suggested research themes which were divided between different uses of forests. About half of the suggestions concerned the relations between timber production and the other uses of forests. The many propositions are due to the fact that timber production in its intensity has strong influence on the other uses of forests. The results of the study have been used in the planning of research in the multiple use of forests.

The study deals with economic significance of forest landscape planning models used in regional planning in Finland. The »judge»-method is used among professional foresters working on private forestry boards in Southern Finland to define their view of what would be moderate level of costs of landscape management for private forest owners. A sample of 154 forest professionals working in district forestry boards in Southern Finland was sent a sociological questionnaire.

It was possible to form three hierarchical moderation classes by statistical grouping of judgement distributions. Prolongations in rotation ages and restrictions concerning ditching of forested bogs, forest read building and clear-cutting were considered the most immoderate models. Rather or wholly insignificant were evaluated such management models, which mean restrictions in »old fashioned» methods or which are already used in practice.

Abstract | View details | Full text in PDF | Author Info

The purpose of this study was to find out about the forest owner’s views on silviculture and any forest management work he had carried out. The data is based on interviews of 289 forest owners in municipalities of Jämsä and Karstula in Central Finland in 1966. The forest owners were a random sample of all males in the municipalities, who alone or together with their wives were in the possession of at least 2 ha of cultivated land and 10 ha of forests.

The forest owners’ attitudes towards silviculture were generally favourable. A common opinion was that money spent on silviculture is a paying proposition (88%), that forest management is better today than it used to be (87%), that cultivation of forests is an economic proposition (81%), and that few owners manage their forests properly unless forced by the law (79%). The need for planning silvicultural measures was also generally accepted (78%).

However, few agreed that the legally imposed silvicultural fee is necessary, that the new silvicultural methods were practicable, or that money he invested in silviculture is profitable to the forest owner. Only 45% agreed that forestry experts have sufficient understanding of the owner’s needs. One third of the forest owners had carried out the following silvicultural tasks: forest cultivation, forest drainage or forest fertilization, on a minimum area of five hectares. Forest cultivation had been carried out by 63%, forest drainage by 44% and forest fertilization by 16% of the respondents. Vast majority (90%) had employed forest experts and a many nearly every year, mainly for marking the trees to be felled.

In the more rural municipality of Karstula, the forest owners’ views towards forestry was more favourable than in the semi-industrialized Jämsä.

The aim of the present study was to describe the diffusion of the professional insight in forestry taking place among forest owners and as factors attached thereto. The material is based on interviews of 289 forest owners in municipalities of Jämsä and Karstula in Central Finland in 1966. The forest owners were a random sample of all males in the municipalities, who were in the possession of at least 2 ha of cultivated land and 10 ha of forest.

Mass media (papers, radio and television) was an important source of information for the forest owners. Forest educational events are specially planned to spread information on forestry to forest owners, but 40% told that they had never participated any such event. Only 8% had got professional forest education. Knowledge concerning forests and forest management may also be inherited from the forest owner’s parents, or in discussions with professional forest officers or neighbours. About 73% of the forest owners had been in touch with professional foresters at least once during the last three years.

A third of the forest owners regarded professional insight their most important source of information on forestry, a little smaller group considered instruction in forestry questions the most important source. The third largest group had achieved their knowledge on forestry on own experience and inherited knowledge. Forest owners favouring mass media, own experience and inherited knowledge were often owners of a small forest holding.

In the 1930s studies showed that state of the standing crop and forests of small private forest holdings in Finland was weak. In 1960s it was regarded necessary to study the possible change in the silvicultural state of these forests. Therefore, sample stands of the small holdings surveyed in 1930 by Osara were surveyed anew in the areas of Karelia and Savo, and in Central Finland in 1963–1964. A line plot survey was combined with ocular estimation as in 1930, but in 1963–1964 the lines and sample plots were placed denser than in 1930 to reach similar number of sample plots.

In 1930 the state of the forests of the small holdings was in average very weak, but according to Osara, the age classes younger than 50 years had similar stand volume than in the all the forests of the southern half of the country. The results of this survey show that the volume, structure, growth and development class structure of the forests in average have improved since 1930. In many respects the forests have reached the average state of forests in the southern half of Finland. The most serious problem is the large proportion of broadleaved trees. Thus, the silvicultural state of the forests should be further improved.

Abstract | View details | Full text in PDF | Author Info

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.

On the basis of time studies on pruning, one thousand stems in four stands was pruned, carried out in 1962. The work was done in two phases with Olli pruning saw, first attached to a shaft about 1.8 metres long and the to a shaft about 4 metres long.

The total time of moving from one stem to another when pruning the stem varied from 0,28 to 0.31 min per stem in the different working sites. The resting time was 19–20% of the effective working time, which included actual pruning time and the moving time. In average, 7.5% of the actual pruning time was unproductive. The actual pruning took in average 0.75–1.1 min/stem in the different sites. The time depended on size of the tree, the DBH, and on the length of the part to be pruned. The total working site time for the pruning was in average 1.34–1.98 min/stem. The output of the work per 7 hours’ working day varied from 226 to 280 stems, and the costs from 10 to 14 pennies per stem.

Abstract | View details | Full text in PDF | Author Info

This paper describes different methods of long-term forecasts in forest management planning with a special attention on intention forecasts for a total forest property or district. Methods for calculating the sustained yield on the basis of the actual increment or the yearly area cut are discussed. It is concluded that a better estimate of the sustained yield is obtainable by the application of a long-term forecast technique. Forecasts for 100 years should not be viewed as plans, but as a background for making short-term decisions. Some of the long-term-type programmes, such as the programme of maximum profit, sustained yield in volume and in money are discussed briefly.

It is pointed out that there is often present a conflict between the various elements of the policy formulated by a forest owner. This leads to the conclusion that the calculations of the profitability of single projects may be misleading.

The precision of a long-term forecast is discussed, and how under certain assumptions the error of the allowable cut is influenced by errors in area, volume, age etc. It is shown that the precision in area and volume is more important in this connection than, say, the precision in increment. In conclusion, existing knowledge, methods and equipment for calculations constitute a basis for long-term forecasts which make them an important instrument in forest management planning.

The present article reviews a geological report given by Daniel Tilas, a Swedish mining manufacturer, towards the end of the 1730s as the report regards information on the Finnish forests. His report gives at hand that forests in several localities southwest of the region demarcated by the towns of Loviisa, Äänekoskei and Kristiina were seriously diminished or burdened by tar burning and shifting cultivation. Larger saw log stands were found mainly in the scaterly populated parishes of Central Finland. Thus, in the chain of ridges between Orivesi and Ruovesi, covering an area of about 4,000 km2, there was a heavily stocked Scots pine forest, as reported by Tilas.

The report given by Tilas is kept in the files of the Geological Research Institute in Helsinki.

The agricultural committee appointed by the Finnish Government in 1958 pointed out a problem that the rural population needed to be ensured employment and earnings from forestry. A forestry study group was called to investigate the effects of forest improvement on employment and income, on four fields: a) forest drainage, b) afforestation, c) thinning of young stands, and d) construction of forest roads. Items a, b and c increase output, and d creates outlets for timber and increases stumpage value.

The study outlined three alternative silvicultural programmes. The Basic Programme corresponds average forest management in Finland in 1953–1959. The Medium Programme can be seen conditional to the realization of the felling plan worked out in a study group Heikurainen-Kuusela-Linnamies-Nyysönen in 1961 in a committee report of Forestry Planning Committee. Finally, according to an Intensive Programme to which forest management, especially afforestation and forest drainage, will be raised to the highest possible level.

The costs of different silvicultural measures of the three programmes were estimated. The allowable cuts were calculated corresponding to the silvicultural programmes for the period 1961–1970 and 2001–2010. After calculating labour input and costs, could the increase in employment and income be estimated for the whole economy, and separately in forestry, communications and industry. When calculating the labour input required for the forest management work and road construction, the probable rise in productivity following mechanization and rationalization has been taken into account.

The present publication concerns the report of the committee appointed by the Finnish Government to draft a programme or the development of Finnish forestry and increase of its production.

Part I of the paper reviews the development of forestry and forest policy in Finland. After the World War II – following the land settlement – ca. 1.5 million hectares of land, mostly owned by the state, was transferred to private ownership. The committee states that because the division of small farms and land settlement policy private forests have tended increasingly to become small forests. The decrease in size of forest units has interfered development of forestry. In part II, the forest utilization programme for the period 1963–1972 is outlined. In the country, logging in 1953–1958 was carried out on a fairly sustained yield basis. The regional picture is, however, not as good, and in Southern Finland there has been over-cutting.

A long-term logging plan was prepared on the request of the committee. The allowable cut following this plan would suffice the calculated wood requirement for the years 1963–1972. In the part III, the committee introduces a silvicultural program for the years 1963–1972 to increase the yield of wood. The targets of logging, sowing and planting, and silvicultural work are considerably greater than what was achieved in the 1950s. To speed up the realisation of the silvicultural programme, working plans should be prepared on a large scale for forest enterprises, afforestation and forest drainage should be increased, and a national seed storage should be established.

Part IV discusses the forest work situation from the stand point of the realisation of the forest utilisation programme and silvicultural programme. Part V introduces a host of recommendations concerning forest policy and economic policy.

Abstract | View details | Full text in PDF | Author Info

The Law on Forest Management Associations was passed in 1950. According to the law, forest owners have to pay a forestry fee, which is used to finance local forest management associatons. The effect of the law on Finnish private forestry is considered to be significant.
The number of consulting forest officers has increased by 95% and the labour input by 107% since the law came into effect. Thus, the guidance available for forest owners has increased markedly. 85% of timber cut from private forests are marked by professional foresters, while the share was earlier less than 30%. The amount of forest management work, such as clearing of felling sites, sowing and care of plantations, has also increased.
On the other hand, experience has pointed out a need for revising some points of the law. To this aim, the Government of Finland appointed a committee to outline the ammendments. The present article contains the report of the committee.
The committee suggests that the forestry fee, that according to the present law is 2-6% of the net yield computed for communal income tax, will be changed to 2-5%. Further, forest holding in which the annual increment is less than 20 cu.m. are at the moment exempt from the fee. It is suggested that holdings with an annual increment of less than 30 cu.m. pay half a fee. In addition, the committee suggests some clarifying provisions to be adopted.

The article is a summary of a presentation by W. Wittich, held in the University of Helsinki in 26.4.1958.
The significance of fertility of the site in tree growh was known already for over 100 years ago in Germany, but after the First World War the view was abandoned in forestry. According to the Dauerwald system of managing forests that was introduced at the time, the type of site was considered relatively insignificant in forest management. Therefore, similar practices were used in all kinds of sites. The opposition against the use of this method resulted in new research on the site factors.
Knowledge of the relation of the site types and vegetation makes it possible to improve productivity: in regional planning the production that is considered to be necessary is assigned to the sites that have best conditions for it. For instance, in Niedersachsen county about 6% of the forest lands are reserved for cultivation of oak.
Another line of soil science studies the root causes behind the hands-on experiences of forest management. The aim is to abandon rigid approaches in forestry. Studying the effects of forest management practices on soil has been targeted, for instance, on effects of clear cutting on decomposition and vegetation, how the soil affects choice of tree species, and decomposition of litter from different tree species. Knowledge of soil and the trees’s demand of nutrients helps to mend disturbancies, such as nutrient deficiensies. Consequently, fertilization has become a new tool to improve productivity in forestry.

The aim of the study was to compare the newly introduced brush cutter to ordinary hand tools in clearing of cutting areas and thinning young birch (Betula sp.) and Scots pine (Pinus Sylvestris L.) stands. Working with a prototype of the brush cutter, Brushmaster, reduced the total working time by 15-20% compared to bush knife and axe, in spite of the cutter’s weight. At rainy weather the advantage of Brushmaster dissapeared because of clogging of the cutter’s air filter. The prototype proved to be more effective when clearing a cutting area, and hand tools seemed to be faster if damage to the remaining trees have to be avoided.

In addition, eight either lighter or more effective motor saws or brush cutters were compared mutually, and the effect of motor effect, weight, handiness, arrangement of suspenders and handles is discussed. With these improved types of the cutter it was possible to shorten the total working time in thinning of stands (mostly clearing of young stands) to 30-40% of the total working time compared to hand tools. The most modern saws appeared to be best adapted in clearing cutting areas.

When resettlement plots have been established in Finland, a so-called household wood principle used to be used: in addition to fields, the new farm has been given forest land enough to supply it household timber. Trees larger than needed for construction of the farm were considered unnecessary, and the valuable timber trees over certain diameter could be harvested by the surrenderer of the land. This has led to fellings at minimum diameter in contrary to rational forest management. The presentation describes new legislation and directions that aim at correcting the situation.

The study is continuation of the earlier structure and growth studies of Scots pine (Pinus sylvestris L.) and Norway spruce (Picea abies (L.) H. Karst.) in Forest Research Institute. The material represents birch stands (Betula verrucosa, now B. pendula, and B. Pubescens L.) in Southern Finland. The stands were treated with different fellings, and in regard to their silvicultural condition classified as good, satisfactory and unsatisfactory. Height of the trees, height of living crown, volume, increment and volume increment and development of stem diameter series was measured.

The most characteristic difference between the silviculturally good and poor stands was that the the annual increment of the good stands concentrated into large size trees, and the increment of unsatisfactory stands into small and inferior trees.

It is concluded that if the aim of stand treatment is to produce large and high quality volume increment, the most favourable stand volume of  birch stands, compared with naturally normal stand volume, seems to be 90-85% at the age of 41-55 years, and 80-70% at the age of 56-65 years. If growth of large size trees is aimed at, the maximum number of the dominant trees per hectares cannot be more than 400 at the age of 50-60 years.

Wood demand and practices in the marking of trees for cutting have affected the silvicultural state of the forests of Finland in the early 1900s. The aim of the study was to study the development of timber sales and the marking of trees for logging, with a special emphasis on variation in the volume of the sales and assortment range. The study is based on statistics of the District Forestry Boards and Forest Management Associations about timber marked for cutting in 1931-1953.

The professionals in the District Forestry Boards and Forest Management Associations have marked annually in average 9 million stems of heavy timber and about 7 million m3 of stacked wood for sales. The volume  follows business cycles, the changes in the volume of stacked wood being larger than of heavy timber. When demand was high, the number of professional workers limited the supply of wood. There were large differences in the volumes marked within the country. The share of small diameter stacked wood has increased since 1930s compared to heavy timber.

A Committee was appointed in 1946 by the government of Finland to draw a draft to substitute the 1928 Law on Private Forests. The article is a report of the committee, and gives a suggestion to a new Forest Management Law and Forest Management Decree.

The aim of the 1928 law was to prevent devastating fellings. The committee introduces a new concept, duty to tend forests in accord with the principle of progressive forestry. This principle is drafted in the first paragraph of the law: Forest should be so tended, protected and used that, as far as possible, the productive capacity of the soil will be fully utilized and economically profitable, and increasing yield secured.

The proposal also includes measures to prevent devastation, the concept of which has been changed from the previous law. For instance, a cutting which is in disproportion to the growing stock of the forestry holding is considered devastation. Responsibility for the measures to secure regeneration after felling rests with the forest owner if the felling has been carried out in line with sound silvicultural practice. The district forestry boards are suggested to be the organizations that supervise the observance of the law.

Abstract | View details | Full text in PDF | Author Info

Fuel shortage during and after the Second World War compelled the Government of Finland to improve the fuel supply. In 1948 the Government appointed a Committee to draft a proposal on use of domestic and imported fuels. Special attention was placed on how to develop use of peat as fuel.

In rural districts, firewood billets and waste wood accounted for 45% of fuel consumption. For other users than the rural population, coal and coke consisted 25%, industrial waste wood 11% and billets 18% of the total consumption in 1938. After the war the use of coal and coke increased and the use of billets decreased.

Due to the decreased demand of billets, their price in the towns fell lower than the production and transport costs from the most remote areas where the wood was harvested. The demand for small sized timber is important for silvicultural reasons, and wood harvesting creates jobs for the rural population, therefore, the Committee proposes that the state supports the production of billets. This could be done by improving the effectiveness of firewood loggings, and by building truck roads and railways.

Small-sized birch is used predominantly as fuel. The Committee considers the growing stock of birch to be the largest unutilized wood reserve. Supported by technological research, it may become a new raw material for sulphate cellulose industry. Use of industrial waste wood as fuel and improvement of heating equipment would improve the competitiveness of fuelwood and peat against other fuels. For the possible interruptions in imports, stocks of foreign fuels should be maintained.

Abstract | View details | Full text in PDF | Author Info

The government of Finland appointed a commission to study how the work of forest owners’ associations could be promoted. In 1936 there was 232 forest owners’ associations in Finland. They had 20,632 members, who owned 1,841,304 hectares of forests. The owners of large forest holdings were overpresented among the members. The associations together with forestry boards were important actors in increasing the productivity of the private forests.

The commission concluded that rational forest management should be extended to all private forests, which could be best achieved through the forest owners’ associations. It suggested that the membership should remain voluntary, and that the financing of the associations would be arranged by self-taxation of the forest owners. The so called forest management tax should be devoted to the local forest owners’ associations. Also the state should continue to support the associations. Both state and the smallest forest holdings would be released from the forest management tax. The companies, estates and other large forest owners that employ their own forest management staff would pay a quarter of the tax. The tax could be based on the area of the forest, income of the timber sold or a combination of these. The commission suggested a forest management law, which would deal with the forest management tax and the forest owners’ associations.

Abstract | View details | Full text in PDF | Author Info

A Committee was appointed in 1931 to prepare a program to improve the trade of small timber and to develop Finnish fuels and their production. The low demand for small timber is caused by the reduced export of Egyptian balks, and decreased demand of fuel wood that have been replaced by the imported fuels, like coal. At the same time, the supply of small timber has grown significantly due to increased thinnings, and better transport facilities that have made timber more accessible. Also, decreasing demand of large timber has increased the supply of small timber. The demand of small timber concentrates on Norway spruce (Picea abies (L.) H. Karst.). The sales of small timber are crucial from the silvicultural point of view. Selection felling of large timber in the past has reduced the supply of logs and led to surplus of small timber.

The article discusses the uses of small timber and potential new fields, such as wood sugar as fodder or refining wood as fuel. The use of timber should be promoted especially in the domestic industry. The Committee suggests funding for an additional forestry teaching post in the University of Technology, for forest technology and forest economics research in the Forest Research Institute, for research in wood technics, and for follow-up of forest sugar and wood gas fields.

Abstract | View details | Full text in PDF | Author Info

As the use and value of forests have increased, forests have been managed more as a business. Financial bookkeeping defines the production costs of wood, costs of forest management work, investments in forest improvement, taxes and administrative costs, income from the sales of forest products etc. Bookkeeping reports the annual costs and income in the forestry, but does not give information of the future profits or appropriate organization of the economy of forestry.

The author introduces a system that he calls “metsänhoitoteknillinen tarkkailu” (silvicultural monitoring), which would give economic information of the forestry, and could also replace a forest management plan in the private forests. The bookkeeping system will list in detail the volumes and areas of fellings and silvicultural measures in different years, and deduce the sustainability of the use of forests and future incomes in forestry.

The forest pathology research has gradually been focused more to avail silcviculture. Forest pathology has contacts to other fields in forest sciences, and can deepen the knowledge of forest management practices. The studies on specific fungal diseases are beneficial to the forestry. Special focus should be put to statistical forest pathology research. In addition, the monitoring of large-scale damages would give new perspective to forest pathology. It should also be compared how fungal diseases differ in managed forests and forests in natural state, and how silviculture can be used to promote the healing of forests.

The article is a review on early forest regeneration and management in Finland. Beginning of the 1900s marks change in attitudes and resources for forest management. The state increased the funding of forest regeneration and improvement in the state forests in 1928. State funding is directed also to forest improvement in the private forests, and organizations established to promote forest management in the private forests are reorganized. For instance, District Forestry Boards were appointed the forest improvement work in private lands, in addition to promotion of private forestry. Sowing increased in the state forests from 772 ha to 1,566 ha, in forests of the forest companies from 3,006 ha to 4,954, and in private forests from 1,417 ha to 1,566 ha in 1923-1926. The figures of private forests are, however, incomplete. The most usual methods are patch sowing and broadcast sowing on snow. Seeds used in sowing increased from 3,357 kg to 14,387 kg, and planting from 413 ha to 1,020 ha in 1923-1930. Almost half of the sown areas were in the state forests, and most of the planted area in the forests of the companies. Scots pine (Pinus sylvestris L.) was the main tree species in artificial regeneration, and Norway spruce (Picea abies (L.) H. Karst.) was more popular in planting.

The article gives a review on the history of forest management in the Northern countries. The article concludes that in the Northern Countries with their immense supplies of forest and small demand, because of sparse population, there was no hurry for developing the study of forest economics, as was the case in Central Europe. It was only when the modern wood using industry had revolutionized the marketing conditions, that the opportunity was provided for forest economics to develop. The paper introduces the book ’Om skogarnas skötsel in Norden’ (Silviculture in the Northern Countries) written by a Finn C.C. Böcker. That paper was compiled in behalf of a request of the king of Sweden, King Carl XIV Johan, who offered a price to a person who would draw a scheme for organizing forestry in Sweden, where Finland at that time belonged to. The prize was divided by Böcker and a swede, af Ström.

Abstract | View details | Full text in PDF | Author Info

The article proposes a plan to improve the efficiency of forest management in the state forests in Finland. The forests are situated mostly in Northern Finland. In 1926 the state forests covered 39.5% of the total land-area of the country, 13,580,611 hectares in total. A proportion of 52.3% of the land was productive forest land, 21.4% forest land of poor growth and 24.8% waste land. Scots pine (Pinus sylvestris L.). predominated 56.9%, Norway spruce (Picea abies (L.) H. Karst.) 30.5% and Betula sp. 11.9% of the productive forest land. The fellings have mainly been selective fellings of sawn timber, because the demand for small timber was small. Due to this, there is lack of seedling and young stands. Metsähallitus (Forest Service) has been able to increase the sales of small timber by increasing delivery loggings over standing sales. The net profit of state forestry was 136 million marks in 1929.

Several factors have had negative impact on profitability of state forestry: Major part of the forests are situated in Northern Finland, they are of poorer quality than the private forests, and they are located unfavorable in terms of wood demand. The means to improve financial result of state forest include expanding transport network, such as railroads and floating channels. The yield of the forests can be substantially increased by draining peatlands, improving the effectivity of forest management and increasing the proportion of delivery loggings. Changing the silvicultural practices alone is estimated to increase the productivity of the forests by 50–100%. However, the costs of the peatland draining and silvicultural work are high, and direct profits can’t be expected until later.

Abstract | View details | Full text in PDF | Author Info

The purpose of this study is to reveal the links between farm forestry and its economic and social environment. The second-stage factor analysis used was based on factor scores per municipality, representing the dimensions of total farm operation and of its economic and social environment. The population was 17 municipalities or groups of municipalities in the South Karelian Forest Board district.

The conclusions of the results are directly applicable only to the ideal types presented. A socio-economic environment marked by industrialization detrimentally affects both the standard of forest management, as assessed subjectively by field workers, and the productivity of logging, as measured by labour input/m3 of output. This finding holds good even despite the modernization of forest management indicated by the adoption of renewal cuts.

The clearest negative factor for forestry is the irrational distribution of forest holdings. This impedes the rationalization of forest management and the efficiency of loggings. Extensive scattering of forest holdings also delays the mechanization of logging. The spread effects of industrialization relate to a higher level of forest management and labour productivity of logging. Family farming links up closest with features that enhance the importance of the forest to the farmer. Such features include regularity and size of delivery cuts.

Centralized agriculture, mainly village settlement areas, displayed the poorest forest management. Problem farms are typified by small farm units, unemployment and a low degree of forest management.

Abstract | View details | Full text in PDF | Author Info

Farm forestry in northern Ostrobothnia has met different kinds of obstacles that decrease its profitability, some national, some local. One of the later is partitioning of land. The purpose of this investigation was to survey the division of farm land in the coastal municipalities of northern Ostrobothnia in Finland, where the conditions are among the most unfavourable in the country in this respect. The material used in the investigation was collected in a previous study about the structure of the farms in the area. First part of the paper summarises the history of partitioning of land in Finland.

The results show that division of the woodlots of a farm are in the coastal municipalities of northern Ostrobothnia very disadvantageous for forestry. The average distance of a woodlot to the farmhouse is 8.3 km, but there is a great variation between the municipalities, and the distance varies from 30 to 1.9 km. The form of the lots, as the long ribbon-like woodlots in the municipality of Liminka, complicates often practical forestry. In addition, the number of separate woodlots is high, in average 9.2 per farm.

The great distance of the woodlots from the main farms hinders the use of forests and diminishes the financial result of forestry. Unfavourable form of the woodlots posts similar hindrances to harvesting of timber and forest management as the long distances and high number of separate plots. The problem is heightened by the abundance of peatlands in relation to productive forest lands in the area.

Abstract | View details | Full text in PDF | Author Info

The forest management practices in Finland are closely related to the industrial history in the country. The selection cutting method used previously has now been gradually disappearing, and differences in the quality of forest management can still be observed between different owner groups. The national forest inventories indicate that farm woodlots show the poorest silvicultural state among the ownership categories. This study analyses social and economic causes responsible for variation in the silvicultural state of farm woodlots managed jointly with a cultivated land holding. The study is based on the data of third national forest inventory in Finland, and a factor analysis was calculated using the data.

Although the model developed explains more than a half of the total variance of the level of silviculture, only less than third of this is clearly explained by economic and social factors. The remaining two thirds are explained by the ’nature factor’, which includes both economic and site factors. This affects the effect of different kinds of forest policy measures. Of the variables in the model, the strongest influence in the level of silviculture have income, size of woodlot, size of land area under cultivation and distribution of forest types. The differences in the level of silviculture between different woodlots and different districts, may be explained by the theory of cumulative process. Regional differences in economic phenomena cannot be explained without taking into consideration the social value hierarchy in each region, which determines the range of variation of economic variables.

This paper is a review on the silvicultural research in Finland, researchers and the main subject of the research within the previous 50 years. The task of silvicultural research is to serve forest management work and create a foundation for the practical operations, on one hand, and to answer to the constantly arising questions in the practice of forest management, on the other.  

Forestry as an independent branch of science began in 1909. At first the research was primarily biological, dealing with both the foundations and practices of silviculture. The main subjects are divided to forest sites and vegetation, biology of trees and stand, and methods of forest management.

The distances between the lines in the line survey in the first two National Inventories of Finland were too long to supply data for every State Forest district. Consequently, the Third National Forest Inventory offered an opportunity to supplement the inventory for State Forests in 1954 and 1955, and to gather data on forest resources of the State Fforests. On the basis of the results, a management plan for the State Forests was drafted. The first part of the paper describes the inventory procedure and results of the inventory, the second deduces future cuttings and a forest management programme.
In 1955 the total land area of the State Forests was 9.49 million ha. Drained peatlands cover 126,000 ha, drainable peatlands 798,000 ha and undrainable peatlands 2,621,000 ha. The average volume of growing stock in all State Forests was 55.2 m3/ha, including productive and unproductive forest land. The average increment in all State Forests was 1,39 m3/ha on productive land and in all lands in average 1,14 m3/ha.
Cutting budgets for the progressive yield were prepared by checking the silvicultural cut and estimating the allowable cut. They were made by age classes, developmental stages and for each region. The stock development was forecasted for a period of 40 years. In average the allowable cut was larger during the first decade than during the second. Allowable cut was estimated by the tree species and by timber assortments. The management plan included future forest management work, such as intermediate fellings, regeneration fellings, site preparation, artificial regenereation, tending of seedling stands, and draining of peatland.

Abstract | View details | Full text in PDF | Author Info

Bark beetle populations live usually in a balance in natural forests, and outbreaks occur seldom. The populations have been found to increase in managed forests. Fellings affect the structure of the forests, which influence the living conditions of the insects, and produce material for reproduction. In this study the occurrence of bark beetles was studied in a forest area in Etelä-Häme in Southern Finland using line plot survey.

The forests in the area were Norway spruce (Picea abies L. Karst.) dominated. Over third of the 140 sample plots studied were in forests which had never been cut or it was over ten years to the last logging. Bark beetles of 26 different species were found in 66 of the sample plots. The most common species was six-toothed spruce bark beetle (Pityogenes chalcographus L.), which was due to the abundance of growth material suitable for the species in the area. New species in the area were common double-eyed spruce bark beetle (Polygraphus polygraphus L.), Pityophthorus micrographus L., and Dryocetes-beetle (either Dryocetes autographus or D. hectographus). The fellings increased the occurrence of beetles. The amount and quality of logging residue affected the abundance of the insects.

A state committee report proposing the enactment of a Forest Management Act has recently been published in Finland. The act is intended to be considerably more binding on forest owners than the present law concerning private forests which it would replace. The author assumes that the publication will raise a keen discussion that will ensue pro and contra the proposed law. The article includes a review of the first draft for a Forest Management Act prepared in the wartime winter of 1944. At that time the then minister of forestry N.A. Osara and professor Eino Saari had studied the draft. The former commented the act to the author by saying that after the return of peace the forests would have to be prepared to be restored to good condition, using radical measures if necessary. He foresaw that a proposal for the forest management law might meet with some resistance, but thought it was important enough to be forced through nevertheless. Professor Saari pointed out that bearing in mind that hardly any other country in the world is dependent upon her forests to such a decree as Finland, the requirement expressed in the draft (forests must be managed with a view to the most advantageous return as regards tree species, quality and quantity) must be considered justified. The author hopes that despite the prevailing resistance foreseen by Osara, a law will be enacted to correct the situation under the present law which tends to leave the management of our forests to the mercy of arbitrary decisions.

The goal of improving forest management and doubling the yield of forests in Finland is a great task that requires law, encouragement, written propaganda, practical advice and purposeful work in the forests. In addition, it requires idealistic promotion and education of the citizens. The article discusses the nature and scope of forest propaganda. Different means of forest propaganda and promotion, such as lectures, films, newspapers, magazines, forest literature, stamps, placards and posters, excursions, exhibitions, fairs, forests along the main roads, competitions, education of youth etc are discussed, and their usefulness assessed.

Abstract | View details | Full text in PDF | Author Info

The archives of the advisory organizations for private forest owners in Finland, Regional Forestry Boards and Forest Management Associations, include statistics of fellings in private forests. This investigation assesses felling areas and proportion of different kinds of fellings in 1945-1952 based on the statistics. The statistics does not include fellings where the trees have been marked by a forest owner.

The total area marked annually for cutting was in average 498,300 ha. As there is 1,24 million ha of private forests in Finland, the marking gives opportunity to improve the silvicultural state of private forest relatively quickly. The share of regeneration fellings has increased after the Second World War in many parts of the country. The result indicates that the annual cuttings in private forests have corresponded the amount of fellings that has been estimated necessary according to the National Forest Inventory. There are, however, big differences between different parts of the country.

Abstract | View details | Full text in PDF | Author Info

The quality of birch (Betula sp.) stands in Perä-Pohjola in Northern Finland is low due to the harsh environment, unsuitable sites for the species and unsatisfactory silvicultural state. A total of 236 sample trees were felled and measured in 8 sample plots. The trees were over 80 years old.

Only third of the stand volume of birch in the stands had adequate quality for merchantable timber. This is due to birch growing often in sites unsuitable for the species, the low density of the stands, the small average size of stems, and the low amount of large sized trees. These problems may contribute to the fact that birch seem to be susceptible to decay. The trees have often grown from sprouts, which leads often to poor stem form and decay. The volume and quality of both pure and mixed birch stands was sufficient only in the most fertile sites. Also, decay was more common in poor sites.

Abstract | View details | Full text in PDF | Author Info

The different kinds of injuries in Norway spruce (Picea abies (L.) Karst.) stands was studied in 52 sample plots in Peräpohjola in the northernmost Finland. The age classes of the stands varied from 100 years to over 220 years. Most of the stands were unevenaged, as is usual in the area.

In the younger age classes (121-160 years) majority of the trees were of normal quality or had smaller injuries in all forest types. In age classes over 160 years the trees of merchantable quality decreased markedly in all forest types. The quality of the trees decreases with the age especially because of butt rot, braking of trees and crooks, forks and heart and top decay caused by the injuries. To ensure future quality it would be important that the stand is healthy from the beginning. When old spruce stands of the area are in large extent diseased by the root rot, it is questionable if they can be regenerated using natural regeneration. The spruce stands of the area are also relatively branchy. This could be prevented by growing the young stands dense. Changing the dominant tree species to Scots pine (Pinus sylvestris L.) in the dry upland forest sites could be a way to improve the quality of the forests in the area.

Abstract | View details | Full text in PDF | Author Info

The Private Forest Act came into force in 1928 in Finland. According to the act, felling of a mature stand should not endanger natural regeneration of the site, and an intermediate felling should not conflict with justifiable thinnings. 18 District Forestry Boards were appointed to enforce the compliance of the act. The aim of this investigation was to study what kinds of violations against the Private Forest Act were found in the fellings, what were the consequences, and how the fellings were overseen.

The investigation is based on 2,477 felling inspections made by the District Forestry Boards in cases where forest devastation was suspected. The report divides the different kinds of violations by the different District Forestry Boards, years, the size of forest holdings, ownership of the forest holdings and by executor of the felling. Over half of the inspections were held on fellings done by the forest owner, 14% by the forest industry, and 11% by a broker of timber. Neglecting the obligation to give a notification of felling had increased in the period of 1929-1938. Also, the cases of forest devastation increased slightly. The report suggests some improvements in the act that would, for instance, increase activity of the forest owners to give the required notification of fellings before the felling takes place.

Abstract | View details | Full text in PDF | Author Info

This investigation concerns the felling volumes in Finland in 1935-1945 as regards future fellings. The statistics are divided in two time periods: 1935-1939, when there was an upward trend in the trade cycle, and 1940-1945, when the trade was disturbed by the Second World War. Fellings of household timber and for sales are presented separately.

Removal was annually in average 38.1 million cubic meters (cbm) without bark in 1935-1939, and 29.8 million cbm in 1940-1945. According to the statistics, felling volumes decreased by about one quarter after the period of 1935-1945. Reduction was largest in private and company forests, but smaller in the state forests. The increment balance for the 1935-1945 shows an excess of growth that gives an accumulated yield of 24.4 million cbm.

In private forests the cut is about half as large as the growth of the standing stock due to the poor silvicultural condition of the forests. Private forests account for about ¾ of the total forest area in Finland. In the state lands the cut is 130% of the growth. The report introduces also rental cut, a method developed by the writer, which defines the volume to be cut aiming at the same time to optimise the future increase of the yield. The principle is to preserve the young and vigorous stands, while cutting stands that have low growth.

According to the statistics, the felling volume of private forests has followed the variations in demand. It seems likely that in the coming years the fellings will not be kept within the limits calculated by the rental cut. Consequently, the reserve formed during the war will be utilized. To meet the demand of wood, forest management must be improved and preference should be given to regeneration fellings. Improving transportation systems, such as roads, would give access to forest resources that are now difficult to harvest.

Observatons of drying of Norway spruce (Picea abies (L.) Karst.) stands increased in 1930s in Southern Finland. The aim of the study was to analyse the advance and causes of drying. The work was begun in 1930s before the Second World War, and the damages caused to the forests by the war was used as supplemental observations in the study. A special method, drying analysis, was developed to study the process. It was used both in cases of insect and fungal diseases in the four research areas in Raivola and Ruotsinkylä. In addition, 7 observation areas were studied.

Several causes for drying of the trees were observed in the Norway spruce stands. These included European spruce bark beetle (Dendroctonus micans), root rot (Heterobasidion annosum), pine weevils (Pissodes sp.), bark beetles and honey fungus (Armillaria mellea).

The role of primary and secondary causes for drying, resistance of the trees and the drying process are discussed. Finally, the influence of forest management in drying process is analysed. Forests in natural state can be considered to be in an ideal balance. On the other hand, forest management can be used to maintain the vitality and resistance of the forests. Drying of Norway spruce stands can be taken into consideration when the stands are managed.

Organized forest management begun in Finland in the middle of 19th century. The first method applied in Finland was based on annual cutting area and mainly used in state forests. By the beginning of 20th century saw-timber selection became the most usual felling method. Gradually the main principle changed to forest management by stands and revision of forest working plan.

Abstract | View details | Full text in PDF | Author Info

The aim of the investigation was to study the effect of size of a forest holding to its forest resources or state and quality of the forests. The data was collected in the second national forest inventory in Finland, carried out in 1936-1938. The study focuses on farms in two areas in Southern Finland: provinces of Pohjois-Häme and Satakunta, and provinces of Uusimaa and Kaakkois-Häme.

In 1938 about 53% of forests in Finland were owned by private forest holdings, the sizes of which varied from under 5 ha to over 1,000 ha. About 75 % of the holdings were under 50 ha. After 1918 the number of private forest holdings increased markedly, mainly due to settlement and tenant farmers gaining ownership to their farms.

The smaller the forest holdings were, the poorer was the silvicultural state of the forests and the smaller the standing stock. When the area of the forest holding increases, also the volume of the standing stock per hectare, the number of timber-trees, and average size of the timber trees increases. This is due to larger proportion of older age-classes and somewhat better forest management. Fellings have usually been stronger in the smaller forest holdings. The poor state of the forests originates often from use of the forests before the present ownership, such as slash and burn culture, grazing and cutting wood for household use. To improve the state of the forests, education and forest improvement practices are needed.

According to the 1st national forest inventory of Finland, municipalities owned 178,000 hectares of forests in 1922, about 0.7% of the total forest area of the country. Only 60,000 hectares of these belonged to urban municipalities. The amount had increased to 73,000 hectares by 1938. Although the area was small, forests were important for municipal economy. The aim of this study was to investigate the state and forest management practices of forests in urban municipalities. The data was collected mainly by interviewing the authorities of the municipalities in 1936-1938.

Forests covered 50-80% of the area of the urban municipalities, the total area varying from 111 hectares to 7,791 hectares. Only four municipalities owned more than 5,000 hectares of forests. Annual profit of forestry in all urban municipalities totalled about 4.6 million Finnish marks in 1931-1935. Quality of productive forest lands was relatively good, but the volume and growth of the forests rather low. The silvicultural state of the forests could be improved. The article points out that this requires continuous planning. The basis of this is forest management plan, which has been demanded of municipal forests since 1893. However, some of the urban municipalities still lacked a forest management plan, or it was not fully used in forest management.

The aim of the study was to find out what are the causes of damage in Scots pine (Pinus sylvestris L.) stands and the frequency of different kinds of injuries, which are then discussed in relation to the silvicultural state and management of the stands in comparison to ideal forests. Sample plots were studied in over 80-year old Scots pine dominated stands in mineral soil sites of different forest types in Northern Finland in the area of Perä-Pohjola. 10–40 trees were chosen as sample trees in each sample plot. The sample trees were felled, and the diameter, height of crown and injuries outside and inside of the stem were recorded.

Length of knot-free part of the stem was higher in the dominant trees and in older age classes of the trees. The form of the stem becomes broader and rounder with the age. The crowns are, however, longer in Northern Finland compared to Southern Finland. In management of Scots pine stands, all trees diseased by Scots pine blister rust (Cronartium flaccidum) should be removed. The disease is common in Northern Finland, and the number of diseased trees increases as the stands get older. Decay was more common in trees that had fire wounds. In general, injuries decreased the length and diameter growth of the trees. From the dominant trees should only injured and diseased trees removed in the thinnigs. Codominant trees can be left to grow when spare trees are needed to replace missing dominant trees. Detailed instruction of selection of the removed trees are given for each age class.

Residences of priests in Evangelical Lutheran parishes in Finland, and the forest holdings belonging to them, have been received in different ways. Some have been donated to the church, some belonged originally to the state, and some have been parceled out from the lands of local farmers. The forests holdings were, therefore, not considered to be property of the church. The use of the forests was limited, and they were managed by a forest management plan under supervision of Metsähallitus (Forest Service). The aim of the study was to survey the extent of forests properties of the parishes, how they have been managed, and their incomes to the parishes in 1933-1938.

The 784 residences had 217,600 hectares of forests. The forest holdings of the residences were larger than private forests in general. Also the forest resources, as well as the stocks of standing timber were larger than in private forests. The growing stock has grown further, because increment has exceeded the fellings. The fellings and income of the forestry had been increasing. At the same time, the costs of forestry were increasing. The forest holdings were divided unevenly between the parishes. About 15% of the parishes had no forest income, while the annual income of 10% of them was over 100,000 Finnish marks. In average, the forest income coverd 21.8% of all income of the parishes.

Shifting cultivation, practiced earlier in Finland, was beneficial for grey alder (Alnus incana (L.) Moench). It can produce seeds early and the early growth of the seedlings is fast. Areas where shifting cultivation was intensive, the areas next to the fields were pure alder stands, next circle was Betula sp. dominated, beyond that could be found Scots pine (Pinus sylvestris L.), and finally Norway spruce (Picea abies (L.) H. Karst.). When shifting cultivation ended, Norway spruce became more common. Many young mixed stands had Norway spruce undergrowth and alder overgrowth. The aim of the study was to find out how the stands develop to spruce dominated stands, and how they should be managed.

The density of spruce undergrowth affects the further development of both spruce and alder. The number of alder stems decreases the faster the denser the spruce undergrowth is. Alder overgrowth slow down the early diameter and height growth of spruce compared to pure stands. Also the diameter and height growth of alder remains smaller in mixed stands. The basal area of spruce develops slowly in the beginning, increases significantly by the age of 30, and surpasses the growth of pure spruce stands in Oxalis-Myrtillus site type. Thus, Norway spruce do not suffer from growing in the undergrowth. In the first years, fast growing alder seedlings limits growth of ground vegetation and protects spruce seedlings from frost.  Later thinning or removal of alder benefits spruce growth. The density of spruce undergrowth decides how much alder can be leaved in the stand. If the spruce undergrowth is thin, more alder can be left in the stand.

Abstract | View details | Full text in PDF | Author Info

The shape of land lots formed in parceling of land has been affected by many variables. It is an important economic factor when the land is used in forestry or agriculture. The report concentrates on the larger farms with relatively large forest holdings. In the general parceling of the land that started in the middle of 1700s, the allotted plots were often long and narrow, and the width of the plot could be 20‒50 meters. Later these farms may have been further parceled.

Narrow plots are difficult to manage from the forestry point of view. For example, it is not possible to build a forest road in the plot, and wood harvesting is difficult. To use natural regeneration for a specific tree species is impossible, because the seed trees in the adjacent plot are so near. When the boundaries are long and the properties narrow, there is bigger risk for felling trees on the land of the neighbour. The optimal form for a plot is rectangle which is 3‒6 times longer than its width. Local examples of parceling and the effects of the shape of the plots are given in the article.

Abstract | View details | Full text in PDF | Author Info

The article is a review on the history of forestry in Pekkala estate, a private woodland estate in Ruovesi in Southern Finland. The estate had 7,300 hectares of land in 1929, of which 500 hectares were agricultural lands. It was owned by the Aminoff family since 1822.

The household wood harvesting of the tenants was considered a problem until the farms of the tenants (crofters) became independent in 1921, when the farms of the tenants were parceled out from the main estate. The shifting cultivation of tenants was banned already in 1824. Demand of wood was low until 1870s. in 1865 the freeing of regulation of sawmills increased the demand of wood in Finland, and gave start to significant timber sales in Pekkala estate. The first forest officers were hired in the estate at the time. The first guidelines of forest management for the estate were compiled in 1912, and the first survey of the forests was made in 1916, and repeated in 1922 and 1926. The fellings were planned in consideration of the growth of the forests.

Abstract | View details | Full text in PDF | Author Info

A strip survey was performed in the counties of Sahalahti and Kuhmalahti in Häme, situated in Central Finland, to study the condition of the private forests. The forests cover 78% of the total land area of 37,420 hectares. The forest site types were relatively fertile. Scots pine (Pinus sylvestris L.) dominated forest covered 43%, Norway spruce (Picea abies (L.) H. Karst.) 30% and Betula sp. 23% of the forest land. The productivity of the forests could be improved by changing the species so that they suit the site. The volume of the standing crop is 67.2 m3 per hectare. The volume of the growing stock in the area could be 1 million m3 larger if the forests were nearer to the natural state. The annual growth of the forests is low, and could be much improved by correct forest management.

One of the aims of the survey was to study how the distance between survey lines should be adjusted to give acceptably accurate results, in a way that the strip-survey method can be adapted to large areas. The largest distance between the lines that gave results that differed less than 10% from the correct results, varied between 10 and 1.5 kilometres depending on the variables. For instance, to get accurate results for the rarest forest site types required line distance of 1.5 kilometres, but accurate results for the most common forest site types could be achieves with line distance of 10 kilometres.

About 60%, 20.5 million hectares, of Finland is covered by forests. Of this area 10.5 million hectares are peatlands. The forests are divided in fertile forest land (17 million hectares), forest land of low productivity (3.5 million hectares) and nonproductive lands (about 10 million hectares). Scots pine (Pinus sylvestris L.) is the dominant species in 60%, Norway spruce (Picea abies (L.) H. Karst.) in 23%, and Betulasp. 17% of the forests. The younger age classes are poorly represented, but despite the abundance of older age classes, the growing stock and productivity of the forests are not very high. The reason is low density of the forests, unfavorable tree species composition and the condition of the forests. Timber is used as household timber in towns and in rural areas (16.5 million m3), in traffic (1.3 million m3), fuelwood in industry (3 million m3), raw material in wood industry (9.1 million m3) and export (4 million m3). State owns 36.9% of forest lands, companies and associations 8.1% and other private forest owners 53.5%. The article describes the administration of state and private forests, and forest education in Finland. There was about 600 sawmills, 25 mechanical pulpwood mills, 24 pulp mills and 31 paper mills in the country in 1920.

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.

The fifth part of the six-article series about protection forest in Northern Finland outlines sustainable forest management practices for the Scots pine (Pinus sylvestris L.) forests in the pine timber line area. The author stresses the need to secure the seed production and regeneration capacity of the forests, and the growth and protection of seedlings. At the same time, the local communities’ need for timber has to be taken into account when considering the means to protect the pine forests. The main principle is not to cut more trees than has been regenerated during the time period between good seed years. The article outlines good forest management practices for the timber line area.

The article is divided in six parts. A German summary is in a separate PDF.

A strip survey was made to define the forest and peatland site class distribution and the condition of the forests in Savo and Karelia in central and eastern parts of Finland. According to the survey, 24% of the forested lands are peatlands. Fresh mineral soil sites (26%) were the most common mineral soil site type. Intermediately dry forest soil sites covered 22% of the area, forest sites with grass-herb vegetation 12,79%, rich grass-herb forest soil sites 3,16% and dry forest soil sites 9,59% of the forested area. The most common tree species were Scots pine (Pinus sylvestris L.), 39%, Betula sp., 26%, Norway spruce (Picea abies (L.) H. Karst.), 18%, and grey alder (Alnus incana (L.) Moench), 10% of the forest land. The article includes a review about the wood harvesting in the forests, and their present silvicultural state. According to the study, about 30% of the forested lands (not including peatlands) were unproductive; mostly mixed alder and birch stands of poor quality or open lands.

Two approaches were applied in measuring the scenic value of forest landscapes. In the field, the scenic value of forest lands representing clear cut areas, as well as young closed stands and mature stands with varying tree species composition, were assessed. In the laboratory, the scenic value of the same stands was measured with the help of photographs of the same stand. The same persons representing forest students (36 persons) and city dwellers (25 persons) made the evaluation.

Stands of moderate density containing individual tall trees and a coniferous undergrowth had the greatest scenic value, independently of the tree species composition. However, birch was preferred to Scots pine and Norway spruce. Measurements made in the field by means of interviews, and in the laboratory based on photographs, gave very similar results. Photographs seem to represent a reliable tool for estimating the scenic value of forest landscapes.

The Forest Financing Committee played an important role in Finnish Forestry in the 1960's. This voluntary working group prepared three plans for financing basic forest improvement work from 1965 to 1975.

The report describes the origin of the MERA I (1965–70) and the volunteer work of the Forestry Financing (MERA) Committee in preparing the second and third programmes (1966–75). It deals the initiative of the Committee aiming to finance forest improvement works also from international sources, resulted later on to the Forest Improvement Project (1973–76). Its costs were covered for 16% by the International Bank for Reconstruction and Development in form of a State Loan. The report includes comments about the forest policy in Finland during the 60s and 70s as well as the results of the programmes.
