Between paper and plan: contrasting data on urban habitats in literature with planning documents

In this study, we evaluated the integration of urban habitat data in spatial development documents across Poland’s 28 largest cities and assessed the implications for urban environmental management and biodiversity conservation. The detailed habitat maps identify critical areas for protection, enhancing ecosystem services, and supporting nature-based solutions that positively impact residents’ health and social cohesion. A total of 372 sources were analyzed and 467 habitat types were identified primarily from phytosociological surveys. However, only 33.2% of these habitats have been included in urban planning documents, highlighting a substantial integration gap. Complete taxa lists and habitat maps covering the entire city area, suitable for biodiversity management needs, are rarely included in urban planning documents. The findings have underscored the need for detailed habitat mapping to improve urban environmental management, biodiversity conservation, and public health promotion.
