In boreal forests, wildfires are ecologically and evolutionarily important natural agents of disturbance, and wildfire is known to be a primary driver of community structure and ecosystem functioning. Global change drivers, such as climate warming and land use activities, are predicted to impact future fire frequency and fire behavior, which is likely to have consequences for forest community composition and processes. Likewise, land use changes and management activities are known to exert important impacts on the diversity, composition and functioning of forest ecosystems. While the direct impacts of fire, climate change, and forest management on boreal forest structure and function have been studied intensively, there remains a paucity of knowledge regarding how these factors interact to impact forest dynamic, structure and function. Further, the initial key phase of forest recovery after disturbance includes natural or assisted regeneration of tree seedlings. This is the most sensitive, but also least understood, stage of the recovery phases, hence, my PhD-project aims to specifically fill the existing gap of knowledge in this area.
