Luberon2 is a forest dynamics model with heritable trait variation to simulate the joint effects of natural evolutionary processes including stochastic disturbance, thinning and cutting, and genetic diversity in monospecific stands: it is a demo-genetic agent-based model (Oddou-Muratorio et al, 2020; Lamarins et al, 2022). The current version runs either for cedar (Cedrus atlantica), Douglas fir (Pseudotsuga menziesii), Norway spruce (Picea abies), and larch (Larix sp.). Fir species (Abies sp.) are planned. Using a graphical interactive environment or a script mode, it can be used with various levels of expertise for communication, teaching, training or research purposes. The model is developed on the Capsis modeling platform, available upon request. This user manual contains a synthetic presentation of the model and more detailed documentation on the model. Some sections can be skipped depending on the level of use of the model: (1) simple simulations using pre-existing input files; (2) development of ad-hoc input files for personalized simulations; (3) advanced use of all parameters’ flexibility; (4) extension of the model or re-use of parts of the code. Luberon2 is continuously evolving, the latest version of the user-manual and a quick tutorial to the graphical interface are available on the Capsis website.
