Spatio-temporal vegetation models are essential for simulating dynamics and shifts in species distributions over large areas, particularly under global change. One such model is the dynamic forest landscape model TreeMig. We have developed a frame- work that makes the model more user-friendly, improves its functionality, and expands its possibilities. The framework consists of the improved TreeMig model, the R pack- age ‘TreeMig-R’ for pre-processing input data, model execution and visualization and a graphical user interface (GUI) for ease of use. The code of the TreeMig Package and the GUI is stored here.
