Abiotic and biotic disturbances are expected to increase due to climate change, which could affect the regeneration of boreal forests. Conventional forest management options, as rotation forestry, may increase that risk of disturbances. In rotational forestry, similar-aged trees are planted in the stand, thinned once or twice during the rotation period, followed by a final clear-cut. Thereby, the risk of disturbances is increased through e.g., changes of soil properties, forest structure heterogeneity, and ectomycorrhizal community structure. A functional fungal ectomycorrhizal community is important for the forests, as they are accountant for plant’s water and nutrient supply, and pathogen resistance. In alternative forest management options, as continuous-cover forestry, these risks could be mitigated. In continuous-cover forestry, only singular trees or groups of trees are harvested, which could maintain a higher biodiversity and a more abundant and functional fungal community structure than rotation forestry. This in turn, could enhance the resilience of tree seedlings against disturbances and the regeneration success of forests. Lukas planted 1-year-old pine and spruce seedlings in clear-cut, continuous-cover, and unmanaged forest stands in Hyytiälä and Qvidja. In the next two years, he will conduct several physiological and plant-soil-microbe analyses to study whether the seedlings have acclimatized differently in stands with different management options and how that could affect the resilience of seedlings against drought periods.
