Timo Kuuluvainen. (2002). Natural variability of forests as a reference for restoring and managing biological diversity in boreal Fennoscandia. Silva Fennica vol. 36 no. 1 article id 552. https://doi.org/10.14214/sf.552
In Fennoscandia, use of the natural forest as a reference for restoration and management of forest biodiversity has been widely accepted. However, limited understanding of the structure and dynamics of the natural forest has hampered the applications of the natural variability approach. This is especially the case in areas, where the natural forests have almost totally vanished. This review was motivated by the idea that despite these difficulties the essential features of the natural forest can be reconstructed based on biological archives, historical documents, research done in adjacent natural areas, and modeling. First, a conceptual framework for analyzing the relationship between forest structure, dynamics and biodiversity is presented. Second, the current understanding of the structure and dynamics of natural forests at different spatiotemporal scales in boreal Fennoscandia is reviewed. Third, the implications of this knowledge, and gaps in knowledge, on research and on practical restoration and management methods aimed at forest biodiversity conservation are discussed. In conclusion, naturally dynamic forest landscapes are complex, multiscaled hierarchical systems. Current forest management methods create disturbance and successional dynamics that are strongly scale-limited when compared with the natural forest. To restore some of the essential characteristics of the natural forest’s multiscale heterogeneity, diversification of silvicultural and harvesting treatments, as guided by natural disturbance dynamics, is needed to produce more variation in disturbance severity, quality, extent, and repeatability.

Adam Felton, Erik Andersson, David Ventorp, Matts Lindbladh. (2011). A comparison of avian diversity in spruce monocultures and spruce-birch polycultures in southern Sweden. Silva Fennica vol. 45 no. 5 article id 92. https://doi.org/10.14214/sf.92
The replacement of some spruce monocultures with stands composed of planted Norway spruce (Picea abies) and naturally regenerated birch (Betula spp.) has a range of potential benefits, but the implications for biodiversity are generally unknown. Here we conduct a paired replicated study in southern Sweden of the avian biodiversity found within Norway spruce monocultures, and within Norway spruce stands possessing approximately 20% birch. Our research leads us to three findings. First, avian diversity was significantly higher in the spruce–birch polycultures. Second, spruce–birch polycultures exclusively attracted broadleaf-associated bird species and retained the majority of conifer-associated bird species found in the spruce monocultures. Third, avian biodiversity within the spruce–birch polycultures did not incorporate threatened taxa. We suggest that in addition to the apparent benefits for stand level diversity, widespread use of spruce–birch polycultures could provide a means of softening the matrix for broadleaved-associated species, while concurrently providing an increased broadleaf base from which future conservation actions could be implemented. Our results are relevant to multi-use forestry, and recent policy initiatives by forest certification agencies which aim to increase broadleaf-associated biodiversity within conifer-dominated production forest landscapes.

Thorsten Streyffert. (1954). Forest policy in Sweden. Acta Forestalia Fennica vol. 61 no. 8 article id 7420. https://doi.org/10.14214/aff.7420

Forest policy can be traced several hundred years back in Sweden. One of the early restrictions was related to iron industry, which was dependent on supply of charcoal. This led in the 17th century to the regulation of the industry in order to fit its capacity to the sustained yield of the forests. Also the early sawmill industry was kept under supervision in the mining districts in order not to compete with the iron industry of the forests resources.

In 1903 the fears of shortage of wood, caused by a few decades of unrestricted use of forests and the rise of pulp and paper industries, resulted in the first forest law (enacted in 1905). The leading principle of the law was that the owner of the forest had to secure reforestation after felling. When previously the regulation had limited the fellings within the sustainable yield of the forests, the new law aimed at promoting the productive capacity of the forests. New felling methods were developed and the new practices were spread to the forest owners with help of education, propaganda and giving advice. One important factor in the success of the forest law was founding of County forestry boards, which are the main agencies to materialize the constructive ideas of the new forest policy.

The First National Forest Survey was conducted in 1923-29, followed by the second in 1938, and third in 1954. A new forest law came into force in 1923, which prohibited the cutting of immature forests in other ways than by thinning. In 1948, new amendments of the law were introduced, which, for instance allowed the forest owner to put part of the income derived from the timber sales into a bank account to be later used in reforestation.

Four governmental efforts are underway to reach consensus on indicators of sustainable forestry. Through the Helsinki process, European countries have developed and reached a pan-European, binding consensus, The Montreal process includes non-European Temperate and boreal forest countries, the International Tropical Timber Organization (lTTO) have developed guidelines for the sustainable management of natural tropical forests, and the countries around the Amazon basis have developed a joint initiative for creating guidelines of sustainable forest management of the Amazonian tropical rain forests. It is estimated that as many as 15–20 distinct processes are under way in the private sector by non-profit organizations and for-profit companies, some domestic and other international in scope. Perhaps the most wide-ranging definition work of non-governmental organizations is the undertake by the Forest Stewardship Council, FSC. The paper discusses the Helsinki and Montreal processes and the tasks for research.

Gordon D. Lewis. (1986). The role of policy in forest resource development. Silva Fennica vol. 20 no. 4 article id 5294. https://doi.org/10.14214/sf.a27750

A nation that wishes to enhance its social and economic well-being through more intensive utilization of its forest resources must develop a rather comprehensive policy statement to ensure that the expanded exploitation does not lead to the destruction of these resources. The policy must specify the goals to be achieved, provide general direction on how these goals can be achieved, and develop a system of checks-and-balances to ensure achievement of the long-term objectives. The policy must consider resource protection, the economic needs at the various levels of government, the social impacts of utilization on ways of life in all areas of the nation, and the infrastructure needed in the short and long terms.

Markku Simula. (1985). Forestry and development - a global viewpoint. Silva Fennica vol. 19 no. 4 article id 5248. https://doi.org/10.14214/sf.a15427

The area of world forests is gradually declining because of various human activities, such as shifting cultivation, uncontrolled logging and industrial pollution. Continuation of the trends would have detrimental ecological, economic and social effects on global scale. The diversity of the problem is wide. The situation in the tropical developing countries differs from that in the industrialized world. With the present rates of population growth and unchanged forest policies, the fuelwood shortage in developing countries is rapidly aggravating. The need for more agricultural land tends to prejudice conscious efforts to increase wood production.

The industrialized countries are experiencing problems in introducing forest policy means to maintain sufficient timber supply. Rapidly increasing pollution problem cause a serious hazard to the existence of the whole forest ecosystem. Forestry has primarily been a national issue of relatively low priority in political decision-making, which has resulted in insufficient action to remedy the situation at national and international level.

The renewability of forest resources represents a strategic asset, the importance of which is bound to increase in the long-run potential for badly needed economic and social change in the world’s poor rural areas will be lost.
