​For over four decades, SFBBO's Colonial Waterbird Program has sent trained volunteers into the field each spring and summer to watch over the Bay Area's nesting herons, egrets, cormorants, terns, and gulls. Our annual monitoring report has long been a cornerstone of that effort, combining all the data gathered by our hard-working volunteers on how these majestic birds are faring across the region. In 2020, we undertook a major overhaul of our monitoring protocols to streamline the monitoring protocol. That broke all our old analysis code, and the report went kaput. But that was well worth it for the on-the-ground tradeoff: new volunteers could be onboarded more easily, and more people than ever could participate in avian science! ​And did it ever grow substantially. In 2024, Audubon Canyon Ranch ended their long-running sister monitoring program in the North Bay, and we were able to step in and take the 44 colonies in Marin, Sonoma, Napa, and northern Contra Costa counties under our wing (pardon the pun). That scientific rescue effort required another two years of building relationships, training volunteers, and figuring out logistics before we were ready to publish again. But I’m thrilled to say: the report is back!

‘Twas the day before New Year’s and all through the house, biologists were typing and rereading paragraphs aloud…
 
It’s a cruel fact that projects are often due on the last day of the month, meaning that if it was a year-long project, it’s due on the last day of the year. Therefore, before you head out to your New Year’s Eve festivities, you must first cobble together whatever brainpower survived the onslaught of holiday cookies and poor sleep decisions during the week between Christmas and New Year’s and submit! that! final! report! While generally not anyone’s preferred New Year’s Eve activity, if you’re lucky, the project you’re finishing is interesting and worthwhile. The kind of project that makes you reflect on what you accomplished during the year, appreciate how much you learned, who you worked with, and how your efforts illuminated a new corner of the world you hadn’t considered before.

 As part of our ongoing work to connect people with the Bay’s natural landscapes, we’re sharing a series that explores the story of San Francisco Bay’s tidal marshes — their history, science, and the community efforts that keep them thriving.

San Francisco Bay’s tidal marshes do more than shape the shoreline. They filter water, buffer nearby communities from storms, and store carbon that would otherwise contribute to a warming climate. These wetlands are also home to wildlife found nowhere else, including species specially adapted to life in the tides.

​The Bay’s tidal marshes are humming with song and motion — and we’re working to help keep them that way. At Eden Landing Ecological Reserve, SFBBO’s restoration teams and partners are rebuilding habitat that endangered species depend on, including the Ridgway’s Rail, Salt Marsh Harvest Mouse, and Western Snowy Plover.

The marsh’s recovery is unfolding through a combination of science and stewardship, as recent projects show.

​At Pond A17, our team has been studying how different soil treatments and seeding techniques support native marsh vegetation.

Our story with the marsh began at Pond A6. In 2010, we helped restore 330 acres of a former salt-production pond to tidal action, reopening the area to the natural ebb and flow of the Bay. We scattered native seeds across the newly restored marsh in an aerial seeding effort that helped jump-start plant growth and stabilize the soil. It worked: today, Pond A6 teems with life, from song sparrows trilling in the reeds to herons and rails hunting along the channels.

Once salt flats — now a living marsh.

For decades, the South Bay Salt Pond Restoration Project has been transforming former industrial salt ponds across the Bay into thriving tidal wetlands. These restorations turn salty, barren landscapes into dynamic ecosystems alive with water, vegetation, and the calls of nesting shorebirds.

Tidal marshes are the beating heart of San Francisco Bay — a Ramsar Wetland of International Importance that supports over a thousand animal species and protects our communities from floods and rising seas.
