Embrace the healing power of nature! The City Nature Challenge is back in Pittsburgh for 2021. This year, in light of the COVID-19 pandemic, we have modified the challenge to help keep organizers and participants safe. 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 30, the challenge runs to the end of the day May 3. 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 May 4 – May 9. 

We urge all participants to follow current public health guidelines provided by local governments. Refer to our COVID-19 update page for the latest information.

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.
