Forests are habitat for a large number of species and they fulfil many ecosystem services for society, such as timber production or protection against rockfalls. Climate change is going to alter growing conditions of forest stands substantially during the next decades. One of the biggest challenges for forest management is to take potential shifts in site conditions into account when making decisions about silvicultural treatments and tree species choice. With my research I want to contribute to increase our knowledge about forest development and to support forest management in maintaining the capacity of forests to fulfil societal demands as well in the future.
