Définition de la Trame verte et bleue en presqu’île guérandaise à partir de système d’information géographique

Abstract : As part of the Guérande conurbation community sectorial program (“Schéma de Cohérence Territoriale”) integration of Grenelle Environment Forum, a “green and blue framework (GBF)” (« Trame Verte et Bleue ») has to be defined. It is an environmental tool from the Grenelle Environment Forum (2009) allowing identification and preservation of the ecological reservoirs and corridors. The goal is the strike against the biodiversity erosion. In order to define the intercommunal GBF with a cadastral scale, an ecological landscape study using several subframes (countryside of small fields and hedges, wooded, wetlands and thermophilous dry) was made. Thanks to metric measurements made on land-use data, a 9 connectedness GBF was localized. The connectedness studies physical connectivities between landscape element like alignment of hedges or a hydraulic connexion. Then, this framework was faced with experts’ knowledges, others GFB works on the area and showed to the local politicians to be valided. However, the initial land-use and selected habitats quality lack of data and the lack of methodology (especially the threshold values selection and the lack of species approach) offer drawing improvements and consolidations prospects for the purpose of the application of GFB.
