This dataset, published via the Brittany Region's open data portal, lists individual trees forming tree-lined alignments located on the Public River Domain (Domaine Public Fluvial) managed by the Région Bretagne. For each tree, it provides characteristics such as species, estimated height, trunk diameter, and health condition. The data supports the management and monitoring of tree heritage along navigable waterways under regional authority, and can be used for maintenance planning, landscape assessment, and biodiversity or heritage studies related to Brittany's river network.Caractéristiques des arbres d'alignements présents sur le Domaine Public Fluvial (DPF) de la Région Bretagne comprenant notamment l'espèce, l'évaluation de la hauteur, du diamètre ainsi que l'état sanitaire.
