Chicagoland Partners, Host a City Nature Challenge and Identify Wild Species in Our Region
We’re looking for organizations from nonprofits to nature centers and more! Join the global party and host a City Nature Challenge: Chicagoland Region event anytime from Friday, April 24 to Monday, April 27, 2026. It can be as simple or as complex as you want. Already planning stewardship or volunteer activities in the spring? Want a reason to host a hike, bird walk, or other adventure for kids or adults? Host your event, encourage people to look for wildlife, and upload sightings to the City Nature Challenge Chicagoland Region iNaturalist page.
Learn about the global City Nature Challenge where cities around the world collaborate to share observations of nature. This year's focus is quality additions of wild species to iNaturalist.

Your Data Matters
Knowing what species are in our city and where they are helps us study and protect them, but the only way to do that is by all of us–scientists, land managers, and the community–working together to find and document the nature in our area.
