This paper is a review on the development of sustainable forest management and what has been meant with the term in different times. The article summarises the birth of sustainable use of forests in the world and in Finland, and discusses sustainability in forest management, for instance from the point of view of one forest holding, large clearcuttings performed in Lapland, biological sustainability, business economics and overall planning.

Keywords: forest planning; decision making; sustainable forest management; uneven-aged forestry
Highlights: Scenario analysis and multiple criteria decision analysis were combined to evaluate alternative forest management strategies for Linköping municipality, Sweden; Continuous cover forestry (CCF) promoted ecological and social objectives better than even-aged forestry but was worse for economic objectives; Ecological and social objectives were important to the municipality and thus, in summary, CCF seemed to be a suitable strategy.

Forests are increasingly managed both to provide a sustainable yield of timber and for supplying a range of ecosystem services in line with the concept of sustainable forest management. Several incommensurable interests must then be considered, and it is necessary to strike a balance between different objectives. In evaluation of trade-offs to be made, both objective factors and subjective values need to be taken into account. In recent years, continuous cover forestry (CCF) has been put forward as an alternative to even-aged forestry. The aim of this study was to use scenario analysis in combination with multi criteria decision analysis (MCDA) to evaluate whether CCF is a suitable strategy based on the decision makers’ objectives and preferences for sustainable forest management in a specific landscape. This approach was applied to a planning case on the forest estate of the Linköping municipality in southwestern Sweden. The scenario analyses provided insights into relevant quantitative factors, while the MCDA evaluation helped in clarifying the objectives of the forest management and in assessing the relative importance of various objectives. The scenario analyses showed that in this case CCF is a good management strategy in ecological and social terms but yields worse economic outcomes than conventional even-aged forestry. In the Linköping case, there was a relatively strong emphasis on ecological and social aspects and thus, in summary, CCF seemed to be the most suitable option.

Several international policy processes with sustainable forest management (SFM) as a common goal have emerged during the past two decades. Based on an empirical study from Norway, this paper analyses the role of subjective judgments in assessing national compliance with three international forest policy processes, and the implications for determination of the effects of these processes. The Expanded Programme of Work on Forest Biological Diversity, the Ministerial Conference on the Protection of Forests in Europe and the United Nations Forum on Forests, including its predecessors, collectively provide more than 600 recommendations for SFM. While it is nothing new that SFM encompasses value questions, this paper is a systematic review of where in a process of assessing national compliance the role of judgments is most profound. The paper shows that the multiple objectives of the forest recommendations, references to national circumstances and provisions for stakeholder involvement lead to differing opinions about the degree of conformity between international recommendations and national situation, i.e. compliance. These differing opinions mean different prospects for the international processes to have effects, because only implementation, or active responses to international recommendations, constitutes effects. The roles of judgments and values are recommended topics for further investigation. Factors influencing how compliance is assessed, and consequently the degree to which implementation is deemed necessary, require specific attention. Due consideration to substantive and methodological choices in determining national changes and in separation of other sources of influence will provide a better basis for informed discussion of compliance with and effects of international forest-related policy processes.

The development of standards and guidelines to secure sustainable forest management at different geographical scales has expanded greatly during the past fifteen years. Most of these efforts, however, have been formulated for natural forests only; those designed specifically for forest plantations are relatively few. The global forest plantation area is expanding rapidly, with obvious positive and negative impacts on biodiversity. We characterize the key concepts of biodiversity in tropical and subtropical forest plantations and present an analysis of how these elements are covered in the eight principal operational standards and guidelines for sustainable plantation forestry. We also examine the applicability of standards and guidelines in plantations established and managed under different initial settings. The results indicate that the standards and guidelines address certain key elements of biodiversity comprehensively, meanwhile others are ignored or receive only slight attention. There is also substantial variation between the sets in their nature (performance- vs. process-based), scope, congruity in concepts and hierarchy, and specificity. The standards and guidelines seldom take into account the varying initial settings for plantation establishment and the consequent variation in critical factors in biodiversity conservation and management. We recommend that standards and guidelines should be developed so as to pay more attention to the type and operating environment of plantations, to cover all key factors of biodiversity, and to consider building closer relationships between the social and ecological aspects of biodiversity.

Large parts of the boreal forest ecosystems have been greatly affected by human use, and the current timber-oriented forest management practice that dominates boreal forests is proven to cause biodiversity and ecosystem services declines. These negative effects are mitigated in various ways, including in-situ measures implemented upon harvest. The measures comprise trade-offs between economic and ecological aims; thus, requiring solid knowledge of their effectiveness. However, comprehensive literature review of the effectiveness of such measures is scarce. We aim to fill part of this void by reviewing the scientific literature that have gauged effects of four in-situ conservation measures: green tree retention (GTR), patch retention (PR), dead wood retention (DW) and riparian buffer zones (RB). Two outcomes were considered, species richness and species abundance across taxa.

From a total of 3012 initial papers, 48 met our inclusion criteria that generated 238 unique results. Results were grouped according to control. 178 studies used mature, unlogged forest as control. Out of those, 68% of the findings were not significant, i.e., suggesting no significant impact of harvest with biodiversity measures on species richness and species abundance compared to no harvest. Eighteen percent of the observations showed negative effects and 14% of the observations showed positive effects compared to no harvest. Sixty studies used harvest with no measures as control, of which 45% showed significant positive effects, meaning that compared to harvest with no measures, harvest with conservation measures has positively effects on species richness and abundance. However, 43% of the studies found no significant effect of the implemented conservation measures compared to harvest with no measures taken.

The relatively few significant results reported restrain distinct conclusions on the effectiveness of the assessed conservation measures, but some degree of conservation measure is likely to have positive effects on biodiversity in timber-production forest. However, the scientific basis does not allow for pointing to threshold levels. Higher transparency of study design and statistical results would allow us to include more studies. There is a clear need for more research of effectiveness of common conservation measures in timber-production forests in order to strengthen the knowledge basis. In particular, there are few studies that employ harvest without any conservation measure as control. This is pivotal knowledge for forest managers as well as for policymakers for preserving biodiversity and the ecosystems in forest.
