In French mountain areas, the heterogeneity of forests, the fragmentation of ownership and accessibility constraints hamper inventory and management actions. To ensure the sustainability of ecosystem services provided by forests, it is necessary to evaluate them while taking into account the local and global socio-economic context. The PROTEST project aims to build a methodology for territorial analysis of forest resources, based on advances in remote sensing, GIS, forest dynamics modelling and territorial foresight. The study area of the project is the Geopark Massif des Bauges (France) that contains 50000 ha of forests. The first task is to produce a map of forest resources, based on airborne lidar remote sensing, and of its accessibility, based on the Sylvaccess model. The second task is to implement a territorial foresight work and define forest management scenarios that combine environmental and societal determinants. Societal factors and their possible evolutions will be defined on the basis of field surveys and expert opinions. Depending on these factors and on a typology of parcels, scenarios of forest management will be proposed to simulate the behavior of owners. In the third task, these scenarios will be integrated into a spatialized model of forest dynamics, in order to simulate the evolution of the forest mosaic at the parcel level. Linker functions will be integrated to evaluate ecosystem services (wood production, biodiversity, carbon stock...) from simulated forest characteristics. The results will be used to support participatory workshops that will aim to define a forest management strategy supporting the territorial development.
