  National forest inventories have long and strong traditions in many countries and they can offer a wealth of information about the biophysical aspects of forests such as tree growth, carbon fluxes and biodiversity. However, these are in most cases not paralleled by data representing the socioeconomic dimensions of forests. Integration of socioeconomic and biophysical data has the potential to better unveil interactions between human and natural resources and can therefore better support policy. Climate change has multiple impacts on forest resources. Policies to support sustainable forestry, the bioeconomy, and climate change mitigation and adaptation are constantly developing. At the same time, forest owners’ attitudes and forest markets are evolving. More data is needed to advance the understanding of the links between the human and biophysical factors and the relationship between these factors and the complex objectives of forests. We compared the national forest inventories, national forest owner surveys, and national forest product surveys across Argentina, Finland, Norway, Sweden and the USA. The national forest inventories in all selected countries are built on solid methodological grounds and have strong institutional support and funding. However, the consistency of methods, frequency of implementation, and institutional support for forest owner and forest product surveys are in many cases lacking. There is also a lack of integration between biophysical and socioeconomic data. The USA was the only studied country with integrated biophysical and socioeconomic data. We suggest that this approach reflects the needs of data integration and can serve as a reference for other countries.

  Measures to enhance boreal forests’ biodiversity and climate change mitigation potential are high on the policy agenda. Site productivity influences management, ecological attributes, and economic outcomes. However, national-level analyses of management implementation in response to policies considering site productivity are lacking. We analyzed impacts of a carbon policy (Carb), a biodiversity policy (Bio) and a combined biodiversity and carbon policy (BioCarb) in Norway using a simulation-optimization framework, assessing impacts on forest management, timber harvest, ecological attributes, and carbon fluxes until year 2140. Management alternatives were simulated in the single-tree simulator TreeSim before being fed into a market model NorFor to compare policy outcomes to a business-as-usual (BAU) scenario. All policies led to decreased harvests. Old forests expanded from the current 3% to cover 21% or more of the productive forest area in all scenarios. Impacts of policies depended on site productivity. On low-productive land, management under Bio mirrored BAU, while the Carb and BioCarb policies yielded more set-asides. On high-productive land, management intensity under the Carb policy was similar to BAU but the Bio and BioCarb policies resulted in more set-asides and more old forest. Thus, on low-productive land, the carbon policy showed to have the strongest impact on forest management, while on high-productive land, the biodiversity policy had the strongest impact. With geographical site-productivity gradients, the two policies exhibited different regional effects. The study shows that ex-ante analyses with appropriate tools can provide relevant information of multiple consequences beyond the stated aims which should be considered in policy design.

  It is of global importance to manage boreal forests sustainably as it is one of the largest biomes hosting the most coniferous forest area on the planet. Even-aged management with clearcutting is the dominant silvicultural regime in many Nordic countries including Norway. Policy makers and other decision-makers are seeking ways to increase carbon sequestration in forests. The public and scientific debate over the effects of silvicultural practices on ecosystem services such as biodiversity and forest carbon has intensified. Gaining new insights about the interactions between carbon, timber and biodiversity goals, their trade-offs and synergies will be crucial to developing effective policies. We assessed the effects of climate and biodiversity policies on national-level silvicultural practices, carbon fluxes, and the forest industry. We combined constraints on key forest biodiversity indicators and habitat support features with incremental carbon prices up to 1000 NOK/tCO2eq. Following a two-step procedure, we first applied the tree-level simulator TreeSim to simulate management alternatives that mirror common management practices across Norwegian forests. Then, we applied the optimization model NorFor to compare management regimes, biodiversity levels, forest sector carbon fluxes, and timber and industry production over the next 100 years. Preliminary results showed trade-offs and synergies between carbon, timber, and biodiversity. Higher carbon prices with no biodiversity policy led to higher carbon fluxes and more intensive forest management. With a combined carbon and biodiversity policy, total timber harvest decreased on average by 12% compared to a business-as-usual scenario. With a biodiversity policy without carbon policy, forest management turned into less intensive with the area with no management increasing by about 60 % compared to base levels. Finally, with a combined carbon and biodiversity scenario, forest management intensity was very similar to the base level, suggesting that the base scenario to a large extent supports the combined objectives.
