In the past, the City Nature Challenge has been a friendly competition among 160+ cities worldwide to see who can observe the most species and involve the most citizen scientists. In light of the COVID-19 pandemic, some modifications have been made to help keep the organizers and participants safe. Firstly, this year’s CNC is no longer a competition. Instead, the organizers want to embrace the healing power of nature and encourage the collaborative aspect of the CNC. This will allow people to safely document biodiversity in whatever way they can, even from the safety of their own homes if necessary. All participants are urged to carefully follow public health guidelines provided by their local governments, as they are changing in real-time. Individual safety and public health are the utmost priority. Please refer to the COVID-19 FAQ page for more information.
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!
