  1. 1. Modelling the growth of Pinus sylvestris L. monocultures in Sweden depending on the absorbed light

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Mateusz Grzeszkiewicz; [2022]
    Nyckelord :climate change; forest modelling; light use efficiency; photosynthetically active radiation; Scots pine;

    Sammanfattning : Stand growth models are an important aid in contemporary sustainable forest management as a major planning and decision-making tool. However, climate change influencing growth conditions worldwide is a challenge to commonly used empirical models as they do not provide enough flexibility, which can result in inaccurate predictions and thus wrong decisions and sub-optimal results.
