City Nature Challenge: San Diego
Help San Diego win the 2018 City Nature Challenge
City Nature Challenge, which takes place from April 27-30, 2018, is a worldwide competition to see which city can make the most observations of their local plants and animals over a 4-day period. And San Diego is one of only 35 biodiversity hotspots in the world, so we should have this in the bag!
The global event is organized by Natural History Museum of Los Angeles and California Academy of Sciences, and The Nat is spearheading our local effort. The goal is to document as many species as possible via your smartphone. The event begins Friday, April 27 at 12 AM PT and ends Monday, April 30 at 11:59 PM PT.
You can participate on your own by uploading your photos and obervations of wildlife in your own neighborhood--or wherever you might be in the county that weekend. Are you a social butterfly? If so, we welcome you to participate in one of the many City Nature Challenge programs taking place around the county:
