Silviculture in Finland has been based over decades on even-aged forest management, favoring coniferous single-species stands. Research has shown that mixed forests can provide a wider range of ecosystem services than single-species stands. Changes in the operating environment set new demands for the use of forests. Wood production is one objective, but at the same time, forests are expected to mitigate climate change, protect biodiversity, play an important role in the water and nutrient cycles and provide citizens with recreational opportunities. Mixed forests offer great opportunities for sustainable and multifunctional forest management taken into account climate impacts, resilience, resource efficiency and biodiversity. Wood production can also benefit from mixed forests. Even though the silviculture of mixed forests in Finland would not result in increased wood production, the improved vitality and resistance of mixed forests secure sustainability of wood production in changing conditions. There is urgent need for information on how to grow and manage existing mixed forests and how to establish and grow new mixed forests. To solve these questions, we measured cross sectional data from current young mixed forests (a total of 29 stands) to evaluate past growth and current state of well managed mixed forests. In addition, we established long-term experiments with a clear matrix of different silvicultural options to find out the dynamics of growth by tree species and origin (planting, direct seeding and natural regeneration), and the most effective methods for establishing and managing mixed stands. Totally 18 long-term experiments with 284 plots (1000 m2) were established in 2020-2022. Those experiments will be measured regularly, at early phase with 1-to-3-year interval and later with 5-year intervals. The challenge in establishing long-term experiments is that at the same time we have to consider widely both the current needs and future potential uses for experiments.
