While sustainable forestry in Europe is characterized by the provision of a multitude of forest ecosystem services, there exists no comprehensive study that scrutinizes their sensitivity to forest management on a pan-European scale, so far. We compile scenario runs from regionally tailored forest growth models and Decision Support Systems (DSS) from 20 case studies throughout Europe and analyze whether the ecosystem service provision depends on management intensity and other co-variables, comprising regional affiliation, social environment, and tree species composition. The simulation runs provide information about the case-specifically most important ecosystem services in terms of appropriate indicators. We found a strong positive correlation between management intensity and wood production, but only weak correlation with protective and socioeconomic forest functions. Interestingly, depending on the forest region, we found that biodiversity can react in both ways, positively and negatively, to increased management intensity. Thus, it may be in tradeoff or in synergy with wood production and forest resource maintenance. The covariables species composition and social environment are of punctual interest only, while the affiliation to a certain region often makes an important difference in terms of an ecosystem service’s treatment sensitivity.

Radical socio-economic transition has brought significant yet vaguely understood challenges for forestry in the countries of the former Eastern Bloc. This study narrates the case of the Lithuanian forestry transition, structured along the divides of actor versus structure and material versus ideational world. The narrative exposes remarkably stable forest policy with a significant exception of increased environmental consideration, induced mainly by strong external pressures. The forest policy arena is dominated by state authorities that are grounded in the theory of normal forest, rather distrust private forestry and primarily rely on regulatory instruments. Though the prevailing forestry paradigm has been challenged by researchers, arguing for administrative reforms, increased economic efficiency and larger decision freedom, the alternative ideas were either neglected or denounced fiercely. Such conservatism is a combined effect of ideological heritage of the forestry profession intermingled with vested interests by state forestry authorities.

For forest sustainability and vulnerability assessment, the landscape scale is considered to be more and more relevant as the stand level approaches its known limitations. This review, which describes the main forest landscape simulation tools used in the 20 European case studies of the European project “Future-oriented integrated management of European forest landscapes” (INTEGRAL), gives an update on existing decision support tools to run landscape simulation from Mediterranean to boreal ecosystems. The main growth models and software available in Europe are described, and the strengths and weaknesses of different approaches are discussed. Trades-offs between input efforts and output are illustrated. Recommendations for the selection of a forest landscape simulator are given. The paper concludes by describing the need to have tools that are able to cope with climate change and the need to build more robust indicators for assessment of forest landscape sustainability and vulnerability.

The study conceptualizes economic forest sustainability as “the forest-related income and economic well-being sustained over time” and then compares Lithuania and Sweden at different scales. Sweden adopts a holistic perspective of the forest sector, where forestry and forest industries are perceived as a well-integrated economic branch. Forestry is expected to deliver raw material to forest industries, at the same time creating good preconditions for profitable forest management. Forest owners are given large freedom to act according to market signals and their own household needs, while the resulting intensive forest management cumulatively leads to a significant contribution to the country’s welfare. Lithuania, in contrast, lacks an integrated sector perspective, forestry and forest industries being regarded as two separate realms. Private forest property rights are severely constrained by numerous legislative stipulations, leading to a significant reduction of economic value in production forests. On top of that, thirty percent of private owners face additional restrictions through forestland zoning, leading to further substantial loss of economic value. We suggest several measures for improving the economic forest sustainability in Lithuania, where a genuine national forest program could serve as a suitable bearing medium.

Research Highlights: Validating modelling approach which combines global framework conditions in the form of climate and policy scenarios with the use of forest decision support system to assess climate change impacts on the sustainability of forest management. Background and Objectives: Forests and forestry have been confirmed to be sensitive to climate. On the other hand, human efforts to mitigate climate change influence forests and forest management. To facilitate the evaluation of future sustainability of forest management, decision support systems are applied. Our aims are to: (1) Adopt and validate decision support tool to incorporate climate change and its mitigation impacts on forest growth, global timber demands and prices for simulating future trends of forest ecosystem services in Lithuania, (2) determine the magnitude and spatial patterns of climate change effects on Lithuanian forests and forest management in the future, supposing that current forestry practices are continued. Materials and Methods: Upgraded version of Lithuanian forestry simulator Kupolis was used to model the development of all forests in the country until 2120 under management conditions of three climate change scenarios. Selected stand-level forest and forest management characteristics were aggregated to the level of regional branches of the State Forest Enterprise and analyzed for the spatial and temporal patterns of climate change effects. Results: Increased forest growth under a warmer future climate resulted in larger tree dimensions, volumes of growing stock, naturally dying trees, harvested assortments, and also higher profits from forestry activities. Negative impacts were detected for the share of broadleaved tree species in the standing volume and the tree species diversity. Climate change effects resulted in spatially clustered patterns—increasing stand productivity, and amounts of harvested timber were concentrated in the regions with dominating coniferous species, while the same areas were exposed to negative dynamics of biodiversity-related forest attributes. Current forest characteristics explained 70% or more of the variance of climate change effects on key forest and forest management attributes. Conclusions: Using forest decision support systems, climate change scenarios and considering the balance of delivered ecosystem services is suggested as a methodological framework for validating forest management alternatives aiming for more adaptiveness in Lithuanian forestry.
