This dataset from Rennes Métropole lists urban wasteland sites (délaissés urbains) within the city of Rennes, areas of unused or residual urban land that often support rich biodiversity. It stems from a 2022 study conducted by the DJB (Direction Jardins et Biodiversité) together with the Local Biodiversity Council, providing an initial inventory and assessment of these sites across the city. The data supports urban planning and biodiversity preservation efforts by identifying locations where ecologically valuable but overlooked spaces exist within the urban fabric.It is made freely accessible without authentication via the Rennes Métropole open data portal.Les délaissés urbains sont des milieux riches en biodiversité qu'il est important de préserver. Une étude menée par la DJB et le Conseil Local de la Biodiversité en 2022, a permis un premier travail sur le recensement et l'évaluation des délaissés urbains présents à l'échelle de la ville de Renne...
