Join the Nationwide City Nature Challenge Organized by California Academy of Sciences

March 16, 2017

The California Academy of Sciences is organizing a nationwide City Nature Challenge around Citizen Science Day in April. Last year, it logged about 10,000 iNaturalist observations (more info at: in LA and San Francisco. The California Academy of Sciences expanded to 16 cities this year, one being New York City. The goal of the City Nature challenge is to log as many iNaturalist observations as possible between 4/14 and 4/18. Final totals will be announced on Earth Day.

Interested in participating? There are several ways you can get involved.

1. Make some iNaturalist observations between April 14 and 18. You don’t need to join the CNC:NYC project, any observation you make in the five boroughs during this time will be automatically collected in the project, but if you want to get updates, you can join at:

2. Help spread the word! Let people know that the CNC is happening via Facebook, Twitter, Instagram, a blog post, etc. Tell your students/friends/family to join the effort and help us show those other cities how awesome it is.

3. Host an event! This can be as simple as an info table or as big as a BioBlitz. We don’t have the capacity to add another BioBlitz (we do one in the fall), but if you wanted to do some programming around this event, that would be great! We’re trying to get some info tables set up in locations around the city during the CNC to let the public know what’s going on and to help people join the effort. If you’re interested in this, let me know. We can assign a Macaulay student to you and together you can spend a nice day outside getting people to observe nature.
