The City Nature Challenge is a friendly competition among 160+ cities worldwide to see who can observe the most species and involve the most citizen scientists. You can join the project as a citizen scientist from April 24th to 27th using the iNaturalist app.
Participating in the City Nature Challenge is fun—and it’s a great reason to step outdoors for some time with nature. Your observations of plant and animal life will help scientists collect valuable data on the biodiversity of our planet. AND you’ll help the Washington DC area win!
