City Nature Challenge!

  • The Discovery Center 3401 Reservoir Drive Philadelphia, PA, 19121 United States (map)

Take part in this year’s City Nature Challenge with us! Cities around the world will be competing to see who can make the most observations of nature, find the most species, and engage the most people in the 2019 City Nature Challenge. It’s as simple as finding wildlife, taking a picture of it and noting its location, and then sharing them online at iNaturalist! Learn more at
