Joe Eaton writes about endangered and invasive species, climate and ecosystem science, environmental history, and water issues for ESTUARY. He is also "a semi-obsessive birder" whose pursuit of rarities has taken him to many of California's shores, wetlands, and sewage plants.
By Joe Eaton Environmental issues were important to Michael Montgomery as a young man. Montgomery’s career path led to 33 years with the United States Environmental Protection Agency, where he gained a wealth of experience in navigating complex regulatory landscapes to protect water resources, and ultimately to the San Francisco Bay Regional Water Quality Control Board, where he is now executive officer. “The Bay Area has a strong tradition of coming up with collaborative solutions,” he says. That’s how he...Read More
The California Department of Fish and Wildlife (CDFW) recently updated its distribution map for the state’s river otters, reflecting sightings by citizen-scientist “otter-spotters.” River Otter Ecology Project director Megan Isadore says the map fills in major gaps in the North Bay and East Bay, increasing otters’ documented range by 4,100 square miles. “It’s interesting to find how well they’re doing in very populated cities,” she says. Absent from the Bay Area for decades, river otters were observed near Tomales in...Read More
By Joe Eaton Researchers like Point Blue Conservation Science ecologist Tom Gardali have equipped Swainson’s thrushes, weighing just over an ounce, with tiny, one-gram GPS tags. If recovered, the tag shows the thrush’s exact winter destination, information vital to border-crossing conservation efforts. “You only get a few readings,” says Gardali, “and you still need to get the tag back. But GPS goes to a spot on the map. This is Holy Grail stuff.” Sierra/Cascade thrushes were presumed to migrate to...Read More
By Joe Eaton Delta smelt had a bad year in 2017. Although scientists are still analyzing the data, the message seems to be that strong freshwater flows alone are not sufficient to allow the population to increase. The resulting sense of urgency has led fish biologists to consider how cultured smelt, raised in hatcheries, could be used to supplement the wild population. “We’ve considered the cultured smelt as a lifeboat,” says California Department of Water Resources biologist Ted Sommer. “Now...Read More
Fain, Planning Director for the Bay Conservation and Development Commission (BCDC) since October, was part of a three-person office in the Waterfront and Open Space Division of New York’s Department of City Planning. “We were doing a small study on adaptation options,” she recalls. “In the middle of that, Sandy hit. Suddenly all eyes were on us.” Fain brings that background to a setting unlike New York in many ways. Instead of five boroughs, for example, she’s dealing with a...Read More
By Joe Eaton Microplastics are present in the San Francisco Bay, and at higher concentrations than Chesapeake Bay or the Great Lakes, according to a San Francisco Estuary Institute study led by Rebecca Sutton. There’s “a lot of uncertainty about potential impacts to people and wildlife,” she says.“[Miicroplastics are] a variable contaminant and challenging to interpret.” What we know is sufficient cause for concern: apart from their physical impacts, plastics can absorb other pollutants and some plastic ingredients are known...Read More
Although grebes are primarily fish-eaters (they swallow their own feathers to cushion the sharp bones), this species also consumes significant numbers of crayfish, sometimes detaching the pincers before swallowing the good part. Native to southern swamps and bayous, the red swamp crayfish has been introduced in the Sacramento Valley and San Francisco Delta. According to the US Geological Survey, the species is established at Coyote Hills Regional Park and elsewhere around the Bay. The crayfish preys on the larval stages of...Read More
For the last three years, an environmental storm has been brewing in the North Bay city of Vallejo. Some elements of the story are familiar: grassroots activists pitted against a multinational corporate developer, environmental justice versus the lure of new jobs. Add historical preservation, iconic wildlife, political shenanigans, and the unexpected involvement of the California Attorney General’s office, and the mix becomes more complex. An Irish cement company and its local partners want to build a processing plant and a...Read More
The nonprofit, headed by Stockton tomato packer Dino Cortopassi, is suing TNC and the California Department of Water Resources, which holds a conservation easement on Staten Island, alleging farming practices that cause soil subsidence and threaten levee integrity, and misuse of revenue from farm operations. The 9200-acre farm, acquired by TNC in 2001, is a major destination for migratory greater and lesser sandhill cranes (the latter a California endangered species) as well as Aleutian cackling geese and other birds. As...Read More
Development agreements were already in place for three parcels of land around Dutch Slough when John Cain first took a hike in this West Delta area in the spring of 1999. “It was clear as day to me that removing the levee would be a great way to restore freshwater wetlands at the mouth of Marsh Creek,” says Cain, who now works for American Rivers. Almost two decades later, earthmoving equipment is now preparing 1,178 acres for conversion to marsh...Read More
On multiple fronts, with multiple forces and weapons, California’s battle against invasive aquatic organisms continues. Notoriously, San Francisco Bay is the world’s most invaded estuary. The state’s lakes, rivers, and other freshwater wetlands have their own problematic exotics. Keeping them out, and preventing their spread once established, requires coordination among agencies and levels of government. At best, meshing jurisdictional gears can be a challenge. Legislation pending in Congress could make treating ships’ ballast water to remove invasives yet another source...Read More
It was the culmination of a long struggle for the Jackson-based Foothill Conservancy and other river advocates. Four years ago, a Mokelumne bill was approved by the state Senate but killed by a parliamentary maneuver that blocked a vote in the Assembly. Despite significant support in Calaveras and Amador counties, the bill was opposed by local water agencies concerned about the potential impact on their water rights. In 2015 Assemblyman Frank Bigelow (R-O’Neals) successfully proposed a state study of the...Read More
“Stormwater has traditionally been considered a nuisance or danger in terms of flooding and water quality,” says the Pacific Institute’s Morgan Shimabuku, lead author of Stormwater Capture in California: Innovative Policies and Funding Opportunities, “But we’re starting to see it as more of a resource with potential for water supply.” Shimabuku notes that stormwater capture is also “a great strategy for adapting to climate change, alleviating the impact of high-intensity rainstorms and reducing dependence on other water sources in times...Read More
Situated between trendy Dogpatch and struggling Bayview-Hunter’s Point, the Islais basin is, according to Bry Sarté of Sherwood Design Engineers, “the biggest watershed in San Francisco and home to the city’s most disadvantaged community.” These days, Islais creek is mostly invisible, culverted and paved over between Glen Canyon upstream and its outfall near Third Street. Tasked with restructuring and reimagining the basin as a part of the Resilient by Design Challenge, Sarté and team BIG + ONE + Sherwood began...Read More
“Bay Restoration is a race against time,” says San Francisco Restoration Authority Chair Dave Pine. “That’s why it’s so important to bring the regulatory agencies together to fast-track the permitting process.” The Restoration Authority, overseeing projects funded by Measure AA, took a step forward this June by approving funding for a Regulatory Integration Team. BCDC and six other organizations, including the US Army Corps of Engineer, the US EPA, federal and state wildlife agencies, and the state Water Board, joined...Read More
Former U.C. Davis post-doc Kristen Dybala and her colleagues recently reported in Ecological Restoration on a project that monitored populations of breeding species, mostly songbirds, at the Reserve and 13 other sites along lower Putah Creek from 1999 through 2012. Some sites had seen active restoration efforts to benefit native fish; others had not. Overall, birds seemed to respond to the modified flow regime, with positive trends for 27 species and greater community diversity. Seven riparian-dependent species showed increases in...Read More
For two cold clear days in February, scientists, engineers, and other specialists from all three North American coasts gathered at the Oakland Airport Hilton, in what a local speaker called “the least interesting part of Oakland,” for the second national Living Shorelines Technology Transfer Workshop. The event, co-sponsored by Restore America’s Estuaries, the California Coastal Conservancy, and Save the Bay, featured talks and interactive sessions on this emerging approach to coastal protection that went well beyond technology. Referred to by...Read More
In January, the Bay Conservation and Development Commission and the San Francisco Bay Regional Water Quality Control Board appealed December decisions by a Solano Superior Court Judge concerning Point Buckler and its owner John Sweeney. The decisions voided $3.6 million in fines and cleanup and restoration requirements that the two agencies had imposed on Sweeney for dumping and excavation in Suisun Bay, and draining tidal wetland, without authorization. “If this decision sets precedent, we’re in real trouble,” says Erica Maharg...Read More
The project, along with four others in the Bay Area and Southern California, is featured in a new report, Case Studies of Natural Shoreline Infrastructure in Coastal California. Much of the state’s dunescape was built over or hauled away before its value as habitat for unique species and a buffer against climate change was recognized. San Francisco’s dunes are long gone, and with them the endemic Xerces blue butterfly. Humboldt’s 32-mile stretch still shelters endangered plants like the Menzies’ wallflower...Read More
In January the Bay Conservation and Development Commission and the San Francisco Bay Regional Water Quality Control Board appealed decisions by a Solano County Superior Court Judge voiding $3.6 million in fines and cleanup and restoration requirements that the agencies imposed on the island’s owner for dumping excavation spoil in Suisun Bay and draining tidal wetland without authorization. The agencies held that due to the failure of previous owners to maintain levees, the interior of the island had become tidal...Read More
Nothing could be stranger than sitting in the dark with thousands of suits and heels, watching a parade of promises to decarbonize from companies and countries large and small, reeling from the beauties of big screen rainforests and indigenous necklaces, and getting all choked up.
It was day two of the September 2018 Global Climate Action Summit in San Francisco when I felt it.
At first I wondered if I was simply starstruck. Most of us labor away trying to fix one small corner of the planet or another without seeing the likes of Harrison Ford, Al Gore, Michael Bloomberg, Van Jones, Jerry Brown – or the ministers or mayors of dozens of cities and countries – in person, on stage and at times angry enough to spit. And between these luminaries a steady stream of CEOs, corporate sustainability officers, and pension fund managers promising percentages of renewables and profits in their portfolios dedicated to the climate cause by 2020-2050.
I tried to give every speaker my full attention: the young man of Vuntut Gwichin heritage from the edge of the Yukon’s Arctic National Wildlife Refuge who pleaded with us not to enter his sacred lands with our drills and dependencies; all the women – swathed in bright patterns and head-scarfs – who kept punching their hearts. “My uncle in Uganda would take 129 years to emit the same amount of carbon as an American would in one year,” said Oxfam’s Winnie Byanyima.
“Our janitors are shutting off the lights you leave on,” said Aida Cardenas, speaking about the frontline workers she trains, mostly immigrants, who are excited to be part of climate change solutions in their new country.
The men on the stage, strutting about in feathers and pinstripes, spoke of hopes and dreams, money and power. “The notion that you can either do good or do well is a myth we have to collectively bust,” said New Jersey Governor Phil Murphy whose state is investing heavily in offshore wind farms.
“Climate change isn’t just about risks, it’s about opportunities,” said Blackrock sustainable investment manager Brian Deese.
But it wasn’t all these fine speeches that started the butterflies. Halfway through the second day of testimonials, it was a slight white-haired woman wrapped in an azure pashmina that pricked my tears. One minute she was on the silver screen with Alec Baldwin and the next she taking a seat on stage. She talked about trees. How trees can solve 30% of our carbon reduction problem. How we have to stop whacking them back in the Amazon and start planting them everywhere else. I couldn’t help thinking of Dr. Suess and his truffala trees. Jane Goodall, over 80, is as fierce as my Lorax. Or my daughter’s Avatar.
Analyzing my take home feeling from the event I realized it wasn’t the usual fear – killer storms, tidal waves, no food for my kids to eat on a half-baked planet – nor a newfound sense of hope – I’ve always thought nature will get along just fine without us. What I felt was relief. People were actually doing something. Doing a lot. And there was so much more we could do.
As we all pumped fists in the dark, as the presentations went on and on and on because so many people and businesses and countries wanted to STEP UP, I realized how swayed I had let myself be by the doomsday news mill.
“We must be like the river, “ said a boy from Bangladesh named Risalat Khan, who had noticed our Sierra watersheds from the plane. “We must cut through the mountain of obstacles. Let’s be the river!”
Or as Harrison Ford less poetically put it: “Let’s turn off our phones and roll up our sleeves and kick this monster’s ass.”
4th California Climate Change Assessment Blues
by Isaac Pearlman
Since California’s last state-led climate change assessment in 2012, the Golden State has experienced a litany of natural disasters. This includes four years of severe drought from 2012 to 2016, an almost non-existent Sierra Nevada snowpack in 2014-2015 costing $2.1 billion in economic losses, widespread Bay Area flooding from winter 2017 storms, and extremely large and damaging wildfires culminating with this year’s Mendocino Complex fire achieving the dubious distinction of the largest in state history. California’s most recent climate assessment, released August 27th, predicts that for the state and the Bay Area, we can expect even more in the future.
The California state government first began assessing climate impacts formally in 2006, due to an executive order by Governor Schwarzenegger. California’s latest iteration and its fourth overall, includes a dizzying array of 44 technical reports; three topical studies on climate justice, tribal and indigenous communities, and the coast and ocean; as well as nine region-specific analyses.
The results are alarming for our state’s future: an estimated four to five feet of sea level rise and loss of one to two-thirds of Southern California beaches by 2100, a 50 percent increase in wildfires over 25,000 acres, stronger and longer heat waves, and infrastructure like airports, wastewater treatment plants, rail and roadways increasingly likely to suffer flooding.
For the first time, California’s latest assessment dives into climate consequences on a regional level. Academics representing nine California regions spearheaded research and summarized the best available science on the variable heat, rain, flooding and extreme event consequences for their areas. For example, the highest local rate of sea level rise in the state is at the rapidly subsiding Humboldt Bay. In San Diego county, the most biodiverse in all of California, preserving its many fragile and endangered species is an urgent priority. Francesca Hopkins from UC Riverside found that the highest rate of childhood asthma in the state isn’t an urban smog-filled city but in the Imperial Valley, where toxic dust from Salton Sea disaster chokes communities – and will only become worse as higher temperatures and less water due to climate change dry and brittle the area.
According to the Bay Area Regional Report, since 1950 the Bay Area has already increased in temperature by 1.7 degrees Fahrenheit and local sea level is eight inches higher than it was one hundred years ago. Future climate will render the Bay Area less suitable for our evergreen redwood and fir forests, and more favorable for tolerant chaparral shrub land. The region’s seven million people and $750 billion economy (almost one-third of California’s total) is predicted to be increasingly beset by more “boom and bust” irregular wet and very dry years, punctuated by increasingly intense and damaging storms.
Unsurprisingly, according to the report the Bay Area’s intensifying housing and equity problems have a multiplier affect with climate change. As Bay Area housing spreads further north, south, and inland the result is higher transportation and energy needs for those with the fewest resources available to afford them; and acute disparity in climate vulnerability across Bay Area communities and populations.
“All Californians will likely endure more illness and be at greater risk of early death because of climate change,” bluntly states the statewide summary brochure for California’s climate assessment. “[However] vulnerable populations that already experience the greatest adverse health impacts will be disproportionately affected.”
“We’re much better at being reactive to a disaster than planning ahead,” said UC Berkeley professor and contributing author David Ackerly at a California Adaptation Forum panel in Sacramento on August 27th. “And it is vulnerable communities that suffer from those disasters. How much human suffering has to happen before it triggers the next round of activity?”
The assessment’s data is publicly available online at “Cal-adapt,” where Californians can explore projected impacts for their neighborhoods, towns, and regions.
The results are alarming for our state’s future: an estimated four to five feet of sea level rise and loss of one to two-thirds of Southern California beaches by 2100, a 50 percent increase in wildfires over 25,000 acres, stronger and longer heat waves, and infrastructure like airports, wastewater treatment plants, rail and roadways increasingly likely to suffer flooding.
