Fall Bioblitz

Join Philadelphia and its surrounding counties as we document our fall biodiversity. We’ve done the City Nature Challenge in the spring, but now it’s time to see what we have around us in the fall.

From September 25th (Friday) to September 28th (Monday), we’ll be documenting the plants, animals, and fungi in Philadelphia, Delaware, Montgomery, and Bucks counties in PA and Camden, Gloucester and Burlington counties in NJ. Can we beat our spring totals from the CNC in the fall? What new species are we going to find? Come participate in some community science and help us find out.

Simply download the iNaturalist app on your Android or iOS device and start making observations between September 25th and 28th for them to count towards the bioblitz. You can make observations in your own house or backyard, on your walks around the neighborhood, or anywhere you enjoy the outdoors.

Participating is exactly similar to the City Nature Challenge, except that it is in September. For more detailed instructions, check out our How To Participate page. You can also find more info on using iNaturalist in our Resources page.
