Résumé
In this paper we present the digitalisation of the map of the vegetation of France edited in 64 sheets by the CNRS between 1947 and 1991. The geographical covers and the databases built during this work are gathered in a geographical database called "Base de Données Géographique de la VÉGétation de la France" (BDGveg_FR). The main covers show respectively the vegetation succession stages, as a georeferenced scan, at 1/200,000, and the harmonised map of the potential vegetation, in a vector format, at 1/1,000,000. The harmonised map of the potential vegetation is linked with a national 6-level typology synthesised from the keys of the 64 sheets. The BDGveg_FR is unique because of its period of time, its local and national scales, its exhaustive cover, and its information on the plant associations. Thus, it is actually complementary to the other databases on the French vegetation presently available. It is particularly well appropriate to assess the impact of global changes (e.g. climate, atmospheric pollution) on ecosystem behaviour.
