Long-Term influence of the spatial structure of an initial state on the dynamics of a forest growth model: a simulation study using the Capsis platform

Abstract : Spatially explicit Individual Based Models are more and more often used in forest modelling, especially because they take into account the influence of the spatial structure on the dynamics. However, they are potentially very sensitive to the initial spatial structure used for a simulation, which can be problematic if the initial state is not known, or is simulated in an unrealistic way. The aim of our paper is to study this sensitivity to initial spatial structure in the case of the Mountain model, an individual based model of irregular spruce stands implemented in the Capsis platform. In order to characterise the influence of the initial spatial structure on the dynamics of the model, we simulated different initial spatial structures and compared the results of long term simulations. We showed that the initial spatial structure can highly influence the dynamics of the model, not only during the first cycle of the evolution, but also at very long term in the evolution of the next generations. We also illustrated how some disturbances, such as a periodic gap opening through storms, can modify both the long term dynamics of the stand and the duration of the influence of the initial spatial structure.
