The annual City Nature Challenge is a four day public science event celebrated around the globe and this year will be NYC’s 6th year participating. From April 29, 2022 to May 2, 2022, we are encouraging all New Yorkers - residents, visitors, commuters, students, teachers, pedestrians, park lovers, parents, children, EVERYONE - to help us make as many iNaturalist observations as we can to document the city's biodiversity. Join our 370 cities and thousands of people as we get outside and work together to celebrate urban biodiversity. This collaborative event has grown into one of the largest citizen science events of the year. Globally in 2021, we had over 52,000 people in 419 cities all making over 1 million iNaturalist observations and being thoughtful about nature at the same time. In NYC, we’ll be working together to try to beat our previous year’s totals and we’ll also have some friendly competitions (a Battle of the Boroughs and a Greenspace Race) to see make as many observations and find as many species as we can! The City Nature Challenge is globally organized by the California Academy of Sciences and the Natural History Museum of Los Angeles County.
