Join Golden Gate Audubon, the EcoCenter at Heron's Head, the Port of San Francisco, and the California Academy of Sciences in bioblitzing this hidden gem along the bay in southeast San Francisco! Nature—with the help of hardworking Golden Gate Audubon volunteers—is reclaiming a hidden wetland consisting of nearly five acres of isolated industrial land near Pier 94 on San Francisco’s southern waterfront. Located in the shadow of container ships and heavy equipment, the restored salt marsh and adjacent upland provides valuable habitat for birds, butterflies, and small mammals.

A bioblitz is an intensive, short study of biodiversity in a specific location. We’ll look for birds, mammals, fish, reptiles, butterflies, insects, spiders, trees, flowers, mushrooms, anything!

People of all ages and skill levels are welcome! You bring your curiosity, a smart phone with the iNaturalist app downloaded (or digital camera), and tons of enthusiasm. We’ll rally some experts and folks who know the area. Together we’ll make some science!

The fun starts at 9 am on Saturday, April 1. We'll explore the area and document everything we can find for a couple hours, then we'll all come back together at the EcoCenter at Heron's Head to upload our observations, see what everyone else found, and get help with IDs.

Be sure to register to receive details and information before the bioblitz :
