The 2022 City Nature Challenge is almost here!

The Greater St. Louis Region* is gearing up to compete in the 5th annual City Nature Challenge and we need your participation! The City Nature Challenge (CNC) is a four-day bioblitz-style competition between 350+ cities across the globe to gather observations of nature. Organized by the California Academy of Sciences and the Natural History Museum of Los Angeles, the CNC offers a platform for people to engage in community science by finding and documenting local wildlife. Cities will compete to collect the most observations of nature, document the most species, and engage the most people during the four-day event. Use this Nearby Nature Map to find a participating City Nature Challenge Site near you! Be sure to follow each site's safety policies and procedures. If you can't get out to one of our region's unique nature sites, you can still participate in your backyard! Let's do this, St. Louis!
