Learn about how creek flows affect restoring tidal marshes from Michael MacWilliams of FlowWest, who has modeled hydrodynamics where the Calabazas and San Tomas Aquino creeks meet the salt ponds in northern San Jose as part of Valley Water’s project to connect those creeks with Pond A4.

Learn about San Francisco Bay breeding waterbirds from USGS, which has looked at South Bay avocets, stilts and terns to understand how their abundance has changed since the inception more than 20 years ago of the Restoration Project, as well as the effect on birds of predators and of constructing nesting islands. (The talk may be rescheduled if needed based on agency staffing.)

In order to speed the growth of restoring tidal marsh at the Eden Landing Ponds near Hayward, the U.S. Army Corps of Engineers in late 2023 piled sediments off the Eden Landing shore for waves and tides to bring to the marsh.

Learn about the design and results of this Eden Landing Strategic Placement Project from Julie Beagle of the Army Corps and Jessie Lacy and Karen Thorne of USGS. (The talk may be rescheduled if needed based on agency staffing.)

Lunch and Learn Science: Benefits for Project Monitoring and Decision-making: the Wetlands Regional Monitoring Program and the South Bay Salt Pond Restoration Project – Christina Toms, WRMP & Donna Ball, Restoration Project

Learn how wetland managers across the Bay Area are collaborating to conduct monitoring at a regional scale to save on costs and gain greater understanding of the factors affecting wetland restoration success. Christina Toms of the Regional Water Quality Control Board on June 10, 2025, joined Restoration Project Lead Scientist Donna Ball for a joint presentation on this Bay-wide collaboration, called the Wetland Regional Monitoring Program (WRMP).

Weeding Party at Alviso Marina

Volunteers at work.
Volunteers at work.

You are invited to join Santa Clara County Parks Natural Resource Management team, in partnership with San Francisco Bay Bird Observatory, in their efforts to restore the coastal habitat of Alviso Marina County Park.

Volunteers will assist in the removal of invasive plants and the spreading of mulch in preparation for the planting of native plants.

Youth and families are encouraged to participate. 

Please bring sturdy gloves, closed toe shoes (boots if possible), and your can-do attitudes!

Birdy Hour with Lynne Trulio: Beautiful California Biodiversity - Understanding and Protecting It

Event flyer

We share the Earth with millions of other species.  But, our planet is experiencing a biodiversity crisis in which a significant portion of these species are in danger of extinction in coming decades.  While the Earth has undergone mass extinctions in the past—such as when a meteor strike doomed the dinosaurs—the current mass extinction event is caused by humans.  This loss of species is a tragedy for the Earth’s ecology and non-human inhabitants, but will also have significant impacts on human societies.
