Which city around the world has the most nature? The City Nature Challenge 2019, happening April 26-29, will help us find out!
This annual event is hosted by the California Academy of Sciences. After sweeping the first international City Nature Challenge in 2018, can the San Francisco Bay Area hold onto our title for another year??? In 2018, 68 cities motivated more than 17,000 people to upload 431,000 observations of nature to iNaturalist in the four days of the City Nature Challenge (see 2018 results here). In 2019, more than 150 cities on six continents are taking part, asking residents of and visitors to these urban areas to explore nature all around them and document the species they find!
