Earth Month BioBlitz at the EEC

Join us to learn about the Refuge and contribute to community science by participating in a BioBlitz!

We will lead a leisurely walk in the Butterfly Garden and on the New Chicago Marsh boardwalk at the Alviso Unit of the Don Edwards SF Bay National Wildlife Refuge to look for plants, insects, birds, and much more. This program is suitable for all ages, and the trails are accessible. Those of all experience levels with iNaturalist are welcome to participate. You're also welcome to participate on your own at other parts of the Refuge!
