City Nature Challenge


Take a bow, citizen scientists of St. Louis and the world! Out of 159 cities and regions who competed in the 2019 City Nature Challenge in April, the St. Louis Metro region ranked 13th in number of participants, 22nd in number of observations, and 23rd in number of species. The top 15% in all categories! If you zero in on the Midwest U.S., the St. Louis region was #1 in all categories. Most importantly, we beat Chicago. Just sayin’.
