St. Louis City Nature Challenge

April 30 - May 3


The City Nature Challenge is a fun competition that offers a terrific opportunity to connect with nearby nature. In addition to being fun, a reason to get outside, and a wonderful educational opportunity, the City of St. Louis uses the City Nature Challenge as a way to help build the City’s Urban Biodiversity Inventory through citizen science observations. Information – such as photos taken on your smartphone – that is entered on iNaturalist can be used as an indication of where species are living at a given point in time. The iNaturalist observations collected before, during and after the City Nature Challenge will still be valuable pieces of the St. Louis region’s biodiversity data. See below for links to the iNaturalist Projects.
