Discover iNaturalist and the City Nature Challenge


iNaturalist is a wonderful website where people share images of wildlife and plants. Boulder County has its own project page, and we also participate in an annual bioblitz through iNaturalist that helps document as many plants and wildlife that we can find in one weekend!

Discover some good tips about how to participate in iNaturalist in this virtual training and then jump in to join the City Nature Challenge April 30-May 3!

Registration required. Zoom link will be sent to those registered the day before.


Registration is required through Discover Boulder County, Parks & Open Space’s volunteer and event registration system. If you’re new to the system, you’ll need to create an account. But it’s easy and we only use your contact information to communicate about events you register for. We will never sell or give your information to a third party.
