Lake Merritt Bioblitz – City Nature Challenge 2023

Sunday, April 30 @ 10:00 am - 2:00 pm

Lake Merritt in the heart of Oakland is the jewel of the city and teeming with life. The perfect place to participate in this year’s City Nature Challenge! Join a collaboration of Oakland’s nature and education oriented groups on April 30th to explore and document biodiversity in the city!

The City Nature Challenge has the goal of documenting as much biodiversity in an area as possible. During this event come learn about the thousands of organisms that call this place home and help document them as part of the City Nature Challenge. Local naturalists will be on hand to help you find and identify organisms. Bring your smart phone pre-loaded with the iNaturalist app, food for lunch, and any tools that you think will help you find organisms. There will be stations around the lake focusing on different habitats, organisms and some short guided walks with experts.

You can drop in at any point of the BioBlitz and find a marked area leader to learn from.
To join the the Lake Merritt BioBlitz 2023 project on iNaturalist go HERE and sign up. Don’t forget to turn on the final “yes I want to join” toggle at the end of signup. Help will be provided at kick-off and at tables at lake stations throughout the event.
