GGNRA Endangered Species Big Year Endangered Species Day Celebration

The GGNRA Endangered Species Big Year is a race against time to see and save each of the park's endangered species. On May 18 from 11:30am until 1:30pm, we'll be celebrating national Endangered Species Day at Rodeo Lagoon, located near Ft. Chronkite in the Marin Headlands. This free, fun, and fantastic event will have presentations from the GGNRA's natural resources staff, some free snacks, and then we'll wander Rodeo Lagoon in search of the Tidewater Goby, a small nest-building fish that calls the GGNRA home. We may even have underwater video cameras to aid your search!
