Who We Are
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 400 cities worldwide, with the greater Sacramento region joining in 2019! The Center for Community and Citizen Science at the University of California, Davis, as well as California Naturalist and Wild Davis, facilitates our region’s participation. Participants use the iNaturalist app to photograph, catalogue, identify, and organize observations of local wildlife.
