From April 27 to 30, over 60 cities around the world are competing to see who can document the most diversity in the natural world using the app iNaturalist. Join us at Lake Lagunitas for guided excursions, iNaturalist “how-to’s” and independent identification sessions. Visit http://www.marinwater.org/193/Citizen-Science and follow the steps to join the City Nature Challenge Bay Area group before you start exploring.
