This API provides access to a dataset mapping the hedgerow network (linéaire bocager) recorded in 2020 across the Brittany region of France. It covers hedges and bare or wooded embankments located within agricultural land, digitised as part of collective initiatives supporting hedgerow preservation. The data is published on the Brittany regional open-data portal and is intended to support efforts to improve water and habitat quality and to inform land management and environmental protection policies related to the bocage landscape.Le linéaire bocager est constitué de haies et de talus nus ou boisés localisés dans l'espace agricole breton et vectorisés dans le cadre d'opérations collectives en faveur du bocage. Sa connaissance est essentielle dans les démarches visant à améliorer la qualité de l'eau et des milieux, à lutter...
