As part of the German Biodiversity Assessment (‘Faktencheck Artenvielfalt’), a nationwide review of published studies that recorded species occurrences in urban areas in Germany was conducted. Among other things, the study found that urban areas can host a large proportion of all plant, animal, and fungal species found in Germany, thus contributing to the nationwide conservation of biodiversity. However, compared to other habitat types outside of cities, the number of studies analysing the status and trends of urban biodiversity is relatively small. Relatedly, the study analysed the status of urban biodiversity monitoring by surveying members of the German ‘Municipalities for Biodiversity’ alliance (Kommbio). Based on those findings, the study suggests key attributes of an effective national monitoring system to support urban biodiversity conservation and enhancement.
