City Nature Challenge 2020

What is It?

Macaulay Honors College is thrilled to be the official New York City host of the City Nature Challenge for the 4th consecutive year. We seek a commited corporate partner to join us in supporting science education, sustainability, and environmental awareness.

Throughout the weekend of April 24-27, New Yorkers will come together to photograph examples of urban wildlife at City Nature Challenge family friendly events throughout the five boroughs, hosted by Macaulay Honors College and our corportate partner.

After observation days have ended, the iNaturalist community will help properly identify and catalog the species in a marathon tech session. Final results will be announced by iNaturalist (and on this page).


Why is Citizen Science Important?

Citizen science demonstrates that science is for everyone and can be done by anyone. Participating in scientific efforts helps to improve science literacy for all. City Nature Challenge contributes to our understanding of urban wildlife in New York City and the planet as a whole.


Volunteer Opportunities

For as little as 3 hours (and a brief training) students can receive community service credit for volunteering. There will be convenient locations throughout the city. MORE
