Now in its eighth year, the City Nature Challenge is a global event that calls on current and aspiring nature and science fans, people of all ages and education backgrounds, and community scientists to observe and submit pictures of wild plants, animals and fungi using the free mobile app iNaturalist. CNC kicked off April 28 at 12:01 a.m. in each time zone, and runs through May 1 at 11:59 p.m. You still have time to participate.
Identification of photographed species will be crowdsourced through the online community May 2 — May 7 and results will be announced on May 8. This year’s event will have expanded to more than 450 cities across six continents.
