City Nature Challenge: San Diego
San Diego County places in top three for all categories!
You rock, San Diego! The City Nature Challenge ended Monday, April 30, and the results are now in. San Diego County placed in the top three for all categories—and we are one of only two cities to do so (San Francisco is the other one). We were #3 for both observations and species count and #2 for number of people who participated. This is a great result considering it’s our first year. We could not have done it without all of you as well as our partners who helped support the event, host programs and hikes, and spread the word. Thank you!
The City Nature Challenge is a worldwide competition to see which city can make the most observations of their local plants and animals over a 4-day period. It began Friday, April 27 at 12 AM PT and ended Monday, April 30 at 11:59 PM PT. The global event was organized by Natural History Museum of Los Angeles and California Academy of Sciences, and The Nat spearheaded our local effort. Thanks to everyone who participated, including our partners who hosted events and programs throughout the County (see list below). View a livefeed of results here.
Unlisted City Nature Challenge 2018: Which City Can Find the Most Nature?
Welcome to the 2018 City Nature Challenge!
Over 60 cities will be competing to see who can make the most observations of nature, find the most species, and engage the most people in the worldwide 2018 City Nature Challenge.
People were able to participate by uploading photos and observations of wildlife in their neighborhood--or wherever they were in the county that weekend. More of a social butterfly? If so, folks were welcome to participate in one of the many City Nature Challenge programs taking place around the county.
