Let's go central Ohio! Join your fellow citizen scientists and nature enthusiasts for a weekend-long BioBlitz.

The City Nature Challenge (CNC) is an international citizen science effort to discover and document plants and wildlife in cities across the globe. The observation period of CNC 2021 will take place April 30 - May 3.

It’s easy to get involved using the iNaturalist app (free on the app store). Just take a picture of a plant or an animal and upload it to the app. 

Join the project named 'City Nature Challenge 2021: Central Ohio' and all of your observations will count toward the team's collections. The city with the most observations will be announced as the winner.  

Explore around your city, your own backyard or neighborhood parks. There's nature all around you!
