The City Nature Challenge is an international effort to find and document plants and wildlife in cities across the globe. Join this bioblitz-style competition where cities compete to see which makes the most nature observations, finds the most species and engages the most people.
To participate, download the iNaturalist app (https://www.inaturalist.org). Then, join the City Nature Challenge programs hosted by Great Parks and Cincinnati Parks!
