Résumé :	As the role of forests in mitigating and adaptating to climate change has become a matter of public policy, the need for a tool capable of modelling the complex relationships between climate, species diversity, resilience and productivity has become more pressing. Here, we make a first step in developing such a tool by integrating two independently validated mechanistic models: an individual-based gap-model centered around competition for light, and a species distribution model centered around plant phenology. The performance of the integrated model was tested against forest productivity data from French inventories. When using accurate climate data, the integrated model was shown to perform significantly better than the original model in predicting forest growth. This first validatio[...] As the role of forests in mitigating and adaptating to climate change has become a matter of public policy, the need for a tool capable of modelling the complex relationships between climate, species diversity, resilience and productivity has become more pressing. Here, we make a first step in developing such a tool by integrating two independently validated mechanistic models: an individual-based gap-model centered around competition for light, and a species distribution model centered around plant phenology. The performance of the integrated model was tested against forest productivity data from French inventories. When using accurate climate data, the integrated model was shown to perform significantly better than the original model in predicting forest growth. This first validation opens the way for further integration, and the inclusion of other modules for processes such as drought-induced tree mortality.
