The Ruhr Regional Biodiversity Strategy was adopted in June 2022 by the assembly of the Ruhr Regional Association (RVR). The aim of the strategy is to formulate regionally coordinated goals and measures for the protection and enhancement of biodiversity in the Metropole Ruhr and to guide future measures. The Ruhrgebiet is a polycentric urban area in North Rhine-Westphalia, Germany that is Europe's third-largest conurbation, with more than of 4,438 km² and over 5 million people living in 53 cities and municipalities. As such, this strategy has an extensive focus on urban areas as important areas for biodiversity. The strategy is divided into ten thematic fields, giving focus to the industrial areas of the region and wilderness in urban areas, amongst other topics.
