City Nature Challenge

Friday, April 28, 2023 (All day)

Between April 28 and May 1, 2023, Philadelphia and its adjacent counties will be competing against other cities in the world to see who can find the most species in their regions. If you are interested in contributing and helping Philly win, download the iNaturalist app (or visit the website) and start documenting the wildlife in your area. You can also visit the Philly City Nature Challenge (CNC) project page to see the latest observations as they come in.

The City of Philadelphia alone has recorded more than 325 species of birds. Numerous butterflies including monarchs live and breed in the city. There are snakes, frogs, dragonflies, foxes, bats, and much more to experience in our area. The City Nature Challenge gives us a way to explore and document the biodiversity in the cities and suburbs we call home. This, in turn, is useful for science and conservation.

For information on the City Nature Challenge, tips on participating and to see the other cities competing in 2023 check out City Nature Challenge.
