Transformative Green Infrastructure

At the summit, the BAAQMD’s David Ralson described three examples of redoing infrastructure to break down barriers separating human ecology and the natural environment.  Three such initiatives are underway in the area around San Leandro Bay, the locale of RBD’s Estuary Commons project. “The I-880 corridor from High Street to 98th Avenue contains the worst-off disadvantaged communities in the Bay Area in terms of health outcomes,” he said. “They are also subject to sea-level rise and groundwater inundation.” Former wetlands are now filled with gray infrastructure. Hidden urban creeks, like San Leandro/Lisjan Creek, offer a pathway to reconnection: “People will say, ‘We don’t know about this creek; we don’t have access.’ But their grandparents may have fished or played in...

Reconnecting Mill Creek to its Watershed

For thousands of years, Coho salmon and steelhead returned to spawn in the cold waters of Mill Creek, part of the San Vicente watershed in the mountains above Santa Cruz. This ended when a mining and logging company dammed the creek in the early 20th century. Now, an ambitious conservation initiative has succeeded in removing the dam, bringing people together across local land trusts, Native American groups, regional agencies, and researchers from multiple universities. Valentin Lopez, chairman of the Amah Mutsun Tribal Band, spoke about the dam removal in his session of the Estuary Summit. Mill Creek Dam removal. Photo: Ian Bornarth, courtesy Sempervirens Fund.

Team Tackles Homelessness

“Homelessness is an experience, not an identity,” said Romie Nottage at the Summit’s afternoon session. Her organization seeks to “provide a path to recover from homelessness” rather than treating homelessness as an end-state of being. The “teams” of Downtown Streets Team are unhoused volunteers that work beautification shifts (cleaning streets and alleyways, for example) for a basic needs stipend (food or transportation assistance) and access to case management. Since 2005, when the program began, team members have on average spent about 6 months before finding housing and stable employment. By working towards community beautification and building a roadmap to stable, housed living, Downtown Streets Team is “changing the way the unhoused are perceived in the public eye,” says Nottage. <<...

Invasive Species Breakdown

The invasion of the Delta continues, with new plants and animals threatening to upend ecosystems alongside established non-native species like largemouth bass and spartina. Preventative measures, early detection, and rapid response to novel threats are all key in protecting the Delta from further disruption. But the concepts of community involvement and reconciliation ecology also encourage land managers to consider non-natives with nuance. This means accounting for the cultural and ecological values of invasive species and, in some cases, learning to accept their presence on the landscape while still prioritizing natives. These were among the takeaways of the Estuary Summit’s lunchtime breakout discussion of invasive species in the Delta (one of seven breakout sessions, on topics ranging from water quality to...

Estuary Summit Pivots from Science to People

“Make the unseen more visible in your work,” urged Amanda Bohl, opening speaker for the largely cameras-off audience of 600 virtually assembled for the 2021 State of the San Francisco Estuary Summit this October. The Delta Stewardship Council staffer’s remarks at the 15th biennial conference, usually a two-day, science-and -policy-heavy networking event but this year an eight-hour Zoom summit, referred to how many things we all work on or people we work with everyday remain invisible. Some of these often unseen yet important things brought up over the course of the day: the indigenous lands upon which so many efforts to restore the Estuary or “manage” its resources take place; the people in local communities left out of government decision-making...

Good Policy, More Tests for Living Shores

While more sea walls may soon be necessary to adapt to rising seas, softer, greener, nature-based shorelines will also be important buffers for our cities and waterfronts. Wetlands, oyster reefs, eelgrass beds, and other natural features of shores and shallows figure largely in a number of ambitious, multi-partner restoration projects over the last decade. To date, more than 10 such projects have been or are being restored around the Bay, encompassing more than 200 acres of shoreline and nearshore areas. “We need larger living shoreline projects and we need them fast," said biologist Katharyn Boyer...

Speakers discuss forward-looking science in a rapidly changing environment, and the neuroscience of persuading people to care about climate change.

Climate Change Planning Mark Gold made the ultimate comment in his opening plenary at the State of the Estuary Conference: “The age of incrementalism, and not moving forward in a bold way, is not getting it done in terms of climate change.” Gold, deputy secretary for ocean and coastal policy for the California Natural Resources Agency, outlined the state’s newly revised strategic plan for a bluer economy, coastal resilience, and rapid response to fisheries emergencies. Following his talk, Geeta Persad of the Union of Concerned Scientists reviewed various challenges facing California. “Climate change is going to fundamentally transform where and when California gets its water,” she said. Later, the Delta Stewardship Council’s Yumiko Henneberry asked a panel of scientists what...

Flows and Ecosystem Function Dominate Delta Plan Amendment

With the Delta lagging behind the Bay on four of the State of the Estuary Report’s five indicators, the last long-range plan for restoring its ecological health abandoned, and the threats from climate change becoming ever more alarming, the need for a new regulatory vision for the region may never have been greater. A pending amendment to the Delta Plan, shared by Ron Melcer at the State of the Estuary Conference as part of a policy update session, is meant to provide that vision and the strategies to achieve it. The amendment — to Chapter Four of the Delta Plan, which focuses on the Delta ecosystem — was developed in response to the state’s pivot away from the 2013 Bay-Delta...

Big Picture Review of Regional Science and Governance

Offshore, kelp forests were dwindling. Outside, hillsides were burning. Inside the Scottish Rite Center in Oakland, scientists and policy people were sharing the latest findings concerning the vital shallows in between: the San Francisco Estuary. The patient pursuit of knowledge, essential to smart action in a changing world, had chalked up a fruitful two years. Of the action itself, there was rather less sign. Felicia Marcus might speak to that better than anyone. As chair of the State Water Resources Control Board, she had coaxed along a nine-year process, mandated by law, to raise minimum flows in the major rivers that sustain the Estuary. The Board took the first of several wrenchingly hard decisions 12 months ago. Result: the process...

Speakers talk about emerging water quality issues such as stormwater management, contaminants in effluent, wastewater in Suisun Marsh, and nutrients discharged into the Bay.

Green Diet for Roads City of San Pablo project manager Amanda Booth went deep into the nitty gritty on green stormwater infrastructure at a State of the Estuary Conference session. “Talk to the utility agencies before you even start,” she said. “Read PG&E’s Greenbook guidelines. Know your city’s franchise agreements with gas, electrical, sewer, and water companies, figure out who pays to relocate facilities, for example, if that becomes necessary.” Changing the flow lines of runoff at the street, parcel and regional scale is what stormwater management via green infrastructure is all about. “Regional projects that treat regional drainage are the hardest to site,” said EOA Inc’s Chris Sommer during the session. “To build large stormwater retention projects at a...

Striving for Equitable Outcomes

By Audrey Mei Yi Brown Five people of color, four of whom who were women, took center stage in a full amphitheater for a 2019 State of the Estuary conference panel discussing how to achieve more equitable outcomes in both human and estuary health. Mishal Durrani, an undergraduate researcher at UC Berkeley, observed from the audience. “As a woman of color from an underrepresented community, it was powerful to see a panel with so many women of color represented.” As multi-racial as it was multidisciplinary, the diversity on the stage was striking. From community frontlines to the university to the EPA, each panelist brought expertise in equity work from a different field. Despite the diversity in their fields, it quickly...

Speakers suggest communities could benefit from more green space, local knowledge, and engagement with homeless.

Green Matrix Erica Spotswood, an applied ecologist at the San Francisco Estuary Institute, has spent years studying biodiversity and its importance to ecosystems. “We have lost sight of something that is very simple but is not obvious to us now, which is that we need the same things biodiversity needs,” she said at the conference. She and other SFEI scientists are making the case for increasing biodiversity in cities, and have published a toolkit for how to do so in a recent publication, “Making Nature’s City.” At the same conference, C.N.E. Corbin, a Ph.D. candidate in environmental science at UC Berkeley, said that many cities were built to reflect the idea that cities and nature should not mix. “Historically and...

Speakers discuss issues facing Estuary wildlife and their wetland habitats, as well as drones and other new tools that will help future management.

Fish and Wildlife Check-up State of the Estuary Conference presentations featuring decades of data on fish, ducks, seabirds, and cetaceans revealed both hopeful and alarming trends. “The loss of federal funding for the midwinter waterfowl survey, usually conducted using small aircraft, has researchers looking at drone-based alternatives,” said waterfowl biologist Susan De La Cruz of the US Geological Survey. The overall community condition of the Estuary’s fish (abundance, distribution, diversity, proportion of native to non-native species) has declined, reported the National Resources Defense Council’s Christina Swanson, citing the 2019 State of the Estuary Update, Bay Study and other surveys. The breeding success of California least terns and Brandt’s cormorants reflects the status of the forage fish they feed on, according...

View From the Precipice

By John Hart Scientific studies of the Bay and Delta tend to look intensely at small bits of the system. A countervailing theme at this State of the Estuary conference was the need to see wider, to “zoom out” — and most of all to help the public see the broad view, too.

Smart Plover Predators

The South Bay’s salt pannes, bleak unvegetated flats left behind by commercial salt works, seem inhospitable to life. To western snowy plovers, though, they look like home. Still, the plovers are in trouble themselves. Considered a California species of special concern, the Bay-wide snowy plover breeding population sits at about 250. As Karine Tokatlian explained in her State of the Estuary Conference presentation in October 2017, efforts to boost their breeding success in the remaining salt pannes have encountered unexpected challenges. Predator management resources for the Eden Landing plover colony are limited, according to Tokatlian. Fencing nests work better against mammals, but the plover’s primary predator is the common raven. Relocated predators find their way back. Research on these birds’...
