City Nature Challenge

The City Nature Challenge (CNC) is a 4-day bioblitz where cities around the world compete to see who can record the most wildlife.
Cities are ranked by the total number of observations, the number of species as well as the number of people making observations. Besides being a fun challenge, this is also a great way to engage in citizen science and help document the biodiversity of our urban areas.
The event takes place using the iNaturalist website and app. Any observation photo, geotagged from anywhere in the 7-county area (Philadelphia, Delaware, Montgomery and Bucks counties in Pennsylvania, and Camden, Gloucester and Burlington counties in New Jersey) and time-stamped during the four days of the event, will count towards Philadelphia’s tally.
Visit the CNC Philly home page for detailed instructions on how to participate.
The City Nature Challenge can be fun for nature-lovers of all ages. Get inspired and get outdoors with these fun family activities brought to you by the Academy's Kids Club.
This event takes place using the iNaturalist app in the following locations: Philadelphia, Delaware, Montgomery and Bucks counties in Pennsylvania, and Camden, Gloucester and Burlington counties in New Jersey.
