As part of the DBCLS BioHackathon 2025, we organized a WikiBlitz to improve biodiversity knowledge by integrating iNaturalist, GBIF, Wikidata, and Wikipedia. Participants identified local flora and fauna, filling gaps in multilingual Wikipedia articles. This report summarizes the methodology, results, and insights, illustrating the usefulness of combining citizen science with digital platforms to enrich ecological data and promote biodiversity awareness.
