This geographic dataset covers the entire regional territory using a hexagonal grid that defines the ecological issues underlying the Regional Ecological Coherence Scheme (Schéma Régional de Cohérence Ecologique) for the former Languedoc-Roussillon region in France. Each hexagonal cell combines a set of ecological indicators used to assess habitat connectivity, biodiversity value, and landscape fragmentation. The layer served as a diagnostic tool for regional spatial planning, supporting the identification of ecological corridors and reservoirs to be preserved or restored under the regional scheme. It is published as open data via the regional data portal of Occitanie/Languedoc-Roussillon.Couche géographique recouvrant l'ensemble du territoire régional par des mailles hexagonales définissant les enjeux écologiques conduisant à la définition du Schéma Régional de Cohérence Ecologique en Languedoc-Rousillon.
