Conclusion
SDMs are imperative tools to identify current areas prone to changes in the structure and composition of their ecosystems when faced with future variations in temperatures and precipitation patterns. This study highlights that the pine distribution will likely expand towards higher elevations in Fennoscandia where pine trees are not currently present. Databases sourced from citizen science are extremely useful for the development of robust models that forecast the spatial distribution of species due to their large sample size and the wide environmental gradients where data are collected.
