Embrace the healing power of nature! The City Nature Challenge is back in Pittsburgh for 2024. Using the free iNaturalist app, let’s work together virtually with cities around the world to safely document biodiversity in whatever way we can, even at home or in our neighborhoods.
Kicking off April 26, the challenge runs to the end of the day April 29. Participation is easy! All you need is a camera and the free iNaturalist app (a camera phone or tablet if you have one).
Identification of the photographed species will be crowd-sourced through the online community April 30 – May 5.
Educators: Share the City Nature Challenge with your students. Everything you need to get started is right here in this toolkit, and it can be easily adapted for distance learning.
