Become a scientist for the day at City Nature Challenge at Slide Ranch!

The California Academy of Sciences and the Natural History Museum of Los Angeles County have issued a challenge: who can document the most biodiversity in one week, the San Francisco Bay Area or Los Angeles County? Our vote is for the Bay Area! YOU can help Slide Ranch answer this call to action from the California Academy of Sciences.

Come to Slide Ranch on Saturday April 16 from 2:30-5pm to participate in the City Nature Challenge SF vs LA and celebrate National Citizen Science Day. We will train you to use the iNaturalist app and together will enjoy a special afternoon of Citizen Science using the app to make plant and animal observations around the ranch to study Bay Area biodiversity.

To Participate:

  • download the iNaturalist app ahead of time on your mobile device
  • email to RSVP - participation is free!
  • meet at Slide Ranch at 2:30pm on Saturday, April 16th, with your fully charged mobile device, with the iNaturalist app pre-downloaded, ready to explore and document! All experience levels welcome, and kids younger than 14 should be accompanied by an adult. Slide Ranch staff will begin with an orientation, set out in teams to explore, and then regroup to share the coolest observations. Bring water, snacks, clothes and shoes appropriate for hiking, and sun protection.
