City Nature Challenge 2021

Get ready for this year’s #CityNatureChallenge!

Great Parks has teamed up with Cincinnati Parks and a dozen other regional environmental organizations for the international City Nature Challenge! From Friday, April 30 through Monday, May 3, the event encourages the public to help discover, identify and catalog plants and animals in the region. Locally, the City Nature Challenge is an exciting opportunity to learn more about biodiversity in our community. It is also a chance for us to collaborate with other cities across the world in citizen science. In fact, the 2021 event has expanded to more than 400 cities across six continents!

The City Nature Challenge utilizes the free iNaturalist platform to record environmental data. From April 30 through May 3, participants can log in here and download photos of plants and animals they see anywhere in nature. From May 4 through May 9, all the information gathered will be identified and saved to a database. The data collected will be released May 10 and help create community programming, assist in controlling invasive species and help prioritize natural areas in need of further preservation.

Great Parks will be offering free, naturalist-guided opportunities to encourage participation. Click here to learn more about these programs and the City Nature Challenge. (Note: Protocols from the Centers for Disease Control and Ohio Department of Health, as well as physical distancing and sanitation recommendations, will be followed.)
