It's almost time for the global #CityNatureChallenge, and we need you to help Chicagoland shine!
Our wonderful partners have created more than 20 adventures and need your help to observe the nature around you.
Whether it's a nighttime fungi hike, a party for the planet, or prairie restoration, there's something for everyone. All observations support a global dataset that helps researchers better understand species distribution and urban biodiversity. You just need a phone or camera and your enthusiasm!
