Heermann’s Gull pair bonding at Roberts Lake, by Byron Chin

Note new transit-friendly location! S.F. State University Downtown Campus, 835 Market Street (Westfield Shopping Center, at Powell Street BART station), 6th floor.

Heermann’s Gulls were thought to breed exclusively on small islands in the Gulf of California and off the Mexican coast, where their numbers are declining due to warming seas and overfishing. But in 1999, a few nested on a man-made island on Roberts Lake in Seaside, California—the only known nesting colony of Heermann’s Gulls in the United States. Learn about the natural history of Heermann’s Gulls, the Seaside colony’s growth to 100 individuals, its environmental challenges, and efforts by Monterey Audubon and others to help the colony by monitoring and deployment of a floating nesting island.

Byron and Joanna Chin have been avid birders for over a decade, with a particular love for gulls and other seabirds. They’ve spent the last two years studying the Heermann’s Gull colony in Seaside and have worked closely with Monterey Audubon to conserve them. When not involved in bird-related pursuits, Byron is a patent litigator and Joanna is a pediatrician.…

The San Francisco Estuary Invasive Spartina Project is led by the CA State Coastal Conservancy and the US Fish and Wildlife Service, in partnership with more than 150 landowners and resource agencies in all nine counties of the SF Bay Area.  The overarching goal is to eradicate invasive Spartina in order to enhance ecosystem functions and overall ecosystem health for the benefit of many other native tidal salt marsh dependent fish, migratory birds, wildlife. The project is a critical phase of a major landscape-scale tidal wetlands restoration effort in San Francisco Bay, a collaborative effort by the Coastal Conservancy, San Francisco Bay National Wildlife Refuge Complex, California Department of Fish and Wildlife, San Francisco Bay Joint Venture, East Bay Regional Park District, and dozens of other partners to restore tidal wetlands over the past several decades. Monitoring and treating invasive Spartina is a key step in protecting native coastal wetland habitat for CA Ridgway’s Rail, salt marsh harvest mice, shorebirds and waterfowl, and many other native species in the bay.  The Project has conducted treatment of four species of invasive Spartina since 2005,  and has achieved a 95% reduction in invasive Spartina over the 70,000 acres of tidal wetland and mudflat habitats in the Estuary.  This is accomplished by mapping and treating invasive Spartina across 11 regions bay-wide, propagating and planting 450,000 native plants, and constructing restoration enhancements including 61 high tide refuge islands to date. This presentation will cover the planning and approach to eradicating Spartina while protecting CA Ridgway’s Rail and other native species. Marilyn Latta is a Project Manager at the California State Coastal Conservancy, managing the SF Estuary Invasive Spartina Project, SF Bay Living Shorelines Project, SF Bay Creosote Removal Projects, and additional regional projects and collaborative planning efforts in San Francisco Bay and statewide. She studied Marine Biology/Zoology at Humboldt State University, and prior to joining the Conservancy she worked for a variety of non-profit organizations to educate and involve the public in the protection and restoration of ocean and estuarine resources.  Marilyn manages the large network of local, state, and federal partners engaged in invasive Spartina treatment in San Francisco Bay.  …
