How does it work?

The City Nature Challenge began as a nature-observation competition between the San Francisco Bay Area and Los Angeles County in 2016. Since then, the competition has expanded to over 200 cities worldwide. Participants use the iNaturalist app to photograph, catalog, identify, and organize observations of wildlife in their area. From April 24th-27th, 2020, any iNaturalist post within the Sacramento Region will count towards our totals.  Check out our calendar and map for events occurring in your area!
