Rising seas and frequent storms are battering California’s piers, threatening the iconic landmarks


More storms, rising seas and huge waves are taking their toll on California’s iconic piers that have dotted the Pacific coast since the Gold Rush, posing the biggest threat yet to the beach landmarks that have become a quintessential part of the landscape.

At least a half dozen public piers are closed after being damaged repeatedly by storms over the past two years. Repair costs have climbed into the millions of dollars.

Among those shuttered is the pier in Capitola built in 1857 that predates the northern California town and is a popular spot to watch passing whales and dolphins. Another damaged by storms in San Diego, the Ocean Beach pier, offers a bird’s eye view of surfers carving waves below.

More damage is possible this year with El Nino, which is expected to bring additional storms to California caused by the temporary warming of parts of the Pacific that changes weather worldwide. Back-to-back atmospheric rivers began drenching California on Friday.

City engineers are looking at redesigning piers to withstand bigger surf with a rise in sea levels. Others face relocation or removal.

“We are very much in a changed environment,” said Mike Beck, director of the Center for Coastal Climate Resilience at the University of California, Santa Cruz. “And we’re not going to be able to rebuild back in the same places and in the same ways that we did before. We’re going to have to think more clearly about how we design and where we put these.”

Most piers have undergone major repairs after enduring everything from to fires to erosion. But officials say they are now being damaged at an unprecedented rate.

Waves rising to heights topping 20-feet (6-meters) in late December pummeled the 855-foot-long (260.6-meter) Capitola Wharf in Santa Cruz County, only months after repairs following storms in January 2023 that collapsed a large section. The Capitola Wharf is a pier by nautical standards since it runs perpendicular to the shore, versus a traditional wharf running parallel.

San Diego’s Ocean Beach pier, a nearly 2,000-foot (609.6-meter) concrete structure built in 1966, has been repeatedly battered since 2019. The pier was still undergoing repairs after beatings from high surf that closed it twice last year when a monster swell in January wiped away a piling.

The city is exploring replacing the structure after spending more than $1.7 million in fixes over the past five years. It has secured $8.4 million in state funds for a new one. Among the three proposed designs is one with interconnected pathways, giving it a different look.

California’s state park service demolished the 93-year-old pier at Seaside State Beach near Aptos in Santa Cruz County after a January 2023 storm surge smashed it in half.

Communities are grappling with whether they can afford to keep their piers, which will need taller and stronger pilings that could make their historic look more industrial, Beck said.

But those are tough conversations for many who consider the piers almost sacred.

“It’s sometimes a little bit of a funny thing here in California, the way that we love our piers,” he said.

For generations, the structures have provided families, fishers, tourists and others a peaceful place to experience the ocean without getting wet.

In Ventura, west of Los Angeles, the Visitors & Convention Bureau waxes poetic about the pier built in 1872 that it calls the city’s centerpiece.

“Walk Ventura’s beaches and, in the distance, it wavers like a child’s matchstick project,” the bureau states on its website. “Sit on the sand at its base (on a calm day) and it whispers a lovely song any ocean (and pier) lover knows.”

California’s oldest piers served steamships and were lifelines for settlements to get lumber, bricks and cement with much of the coast decades from being reached by a railroad. Piers were later built for tourism like the Santa Monica pier, which has an amusement park with the world’s first solar-powered Ferris Wheel.

In December, Ventura’s pier already was undergoing repairs from the January 2023 storms when the monster swell that damaged San Diego’s pier around New Year’s eve also wiped away or damaged 19 pilings supporting Ventura’s pier.

Rising sea levels from global warming is causing the waves to be bigger off California’s coast, according to research. The coast is also seeing some of the highest tides of the season.

“We’re really seeing the confluence of all these factors coming together. And that’s going to keep happening,” Beck said. “And here in an El Nino year as well, we also see increases in sea levels, even over and above the kinds of increases that we predict long term with sea level rise.”

During a visit to Capitola last year to assess California’s widespread storm damage, President Joe Biden said global warming is challenging rebuilding efforts.

Capitola’s Public Works Director Jessica Kahn said climate change was taken into account for its $8 million pier project slated for completion this fall.

“The city went over many iterations and different designs and different tactics to make the wharf more resilient and finally settled on widening the wharf,” she said, adding that the narrow part of the trestle will go from three to six pilings.

The new pilings also will have the ability to be raised as sea levels go up.

Kahn said she has no doubt it is worth investing millions to preserve a relic of the past whose sole purpose today is for pleasure, given the number of memories soaked into the wooden wharf.

“When we had our damage here this past January of 2023, you would not believe the amount of phone calls we got. We got obviously from people nearby, but from people who come here annually, people who are out of the country,” she said.

Over the years, Inge Jechart has spent time on the pier gazing down at schools of anchovies being chased by seals as birds circle overhead.

As it undergoes repairs, she now stands on a bluff to watch the crews.

“I think they’re going to do a great job. Yes, we’re having stronger storms, and the weather is changing. But I think we can do it so that it’ll last longer,” she said. “And I think it’s absolutely worth it. It brings a community together. People love walking out there.”

Tiny tracker following monarch butterflies during California migration

Tiny tracker following monarch butterflies during California migration


SAN FRANCISCO (KGO) — When this monarch butterfly hits the sky it won’t be traveling alone. In fact, an energetic team of researchers will be following along with a revolutionary technology that’s already unlocking secrets that could help the entire species survive.

“I’ve described this technology as a spaceship compared to the wheel, like using a using a spaceship compared to the invention of the wheel. It’s teaching us so, so much more,” says Ray Moranz, Ph.D., a pollinator conservation specialist with the Xerces Society.

Moranz is part of a team that’s been placing tiny tracking devices on migrating monarchs. The collaboration is known as Project Monarch Science. It leverages solar powered radio tags that are so light they don’t affect the butterfly’s ability to fly. And they’re allowing researchers to track the Monarch’s movements in precise detail. With some 400 tags in place, the group already been able to get a nearly real time picture of monarch migrations east of the Rockies, with some populations experiencing dramatic twists and turns before making to wintering grounds in Mexico.

“They’re trying to go southward to Mexico. They can’t fight the winds. Instead, some of them were letting themselves be carried 50 miles north, 100 miles north, 200 miles the wrong way, which we are all extremely alarmed by and for good reason. Some of these monarchs, their migration was delayed by two or three weeks.

According to estimates, migrating monarch populations have dropped by roughly 80% or more across the country. And the situation with coastal species here in California is especially dire. Blake Barbaree is a senior scientist with Point Blue Conservation Science. He and his colleagues are tracking Northern California populations now clustered around Santa Cruz.

“This year, there’s it’s one of the lowest, populations recorded in the winter. And the core zones have been in Santa Cruz County and up in Marin County. So we’ve undertaken an effort to understand how the monarchs are really using these different groves around Santa Cruz by tagging some in the state parks around town,” Barbaree explains.

He says being able to track individual monarchs could help identify microhabitats in the area that help them survive, ranging from backyard pollinator gardens to protected open space to forest groves.

“So we’re really getting a great insight to how reliant they are on these big trees, but also the surrounding area and people’s even backyards. And then along the way around the coast, how they’re transitioning among some of these groves. And we’re looking for some of the triggers for those movements. Right. Why are they doing this and what’s what’s driving them to do that? So those questions are still a little bit further out as we get to analyze some more some more of the data,” he believes.

And that data is getting even more precise. The tags, developed by Cellular Tracking Technologies, can be monitored from dedicated listening stations. But the company is also able to crowdsource signals detected by cellphone networks on phones with Bluetooth connectivity and location access activated. And they’ve also helped develop an app that allows volunteers, citizen scientists, and the general public to track and report Monarch locations themselves using their smartphones.

CEO Michael Lanzone says the initial response has been overwhelming.

“We were super surprised to see 3,000 people download the monarch app. It’s like, you know, but people really love monarchs. There’s something that people just relate to,” says Lanzone who like many staffers at Cellular Tracking Technologies, has a background in wildlife ecology.

A number of groups are pushing to have the monarchs designated nationally as a threatened species. If that ultimately happens, researchers believe the tracking data could help put better protections in place.

“They’re highly vulnerable to, you know, some of the different things that that that we as humans do around using pesticides and also potentially cutting, you know, cutting down trees for various reasons. Sometimes they’re for safety and sometimes it’s, you know, for development. But so having an understanding of how we can do those things more sensibly and protect the places that they need the most,” says Point Blue’s Barbaree.

And it’s happening with the help of researchers, citizen scientists, and a technology weighing no more than a few grains of rice.

The smartphone app is called Project Monarch Science. You can download it for free and begin tracking.

Poisonings from ‘death cap’ mushrooms in California prompt warning against foraging

Poisonings from ‘death cap’ mushrooms in California prompt warning against foraging


After a string of poisonings from “death cap” mushrooms — one of them fatal — California health officials are urging residents not to eat any foraged mushrooms unless they are trained experts.

Doctors in the San Francisco Bay Area have blamed the wild mushroom, also called Amanita phalloides, for 23 poisoning cases reported to the California Poison Control System since Nov. 18, according to Dr. Craig Smollin, medical director for the system’s San Francisco division.

“All of these patients were involved with independently foraging the mushrooms from the wild,” Smollin, who is a professor of emergency medicine at the University of California, San Francisco, said at a news conference Tuesday. “They all developed symptoms within the first 24 hours, including nausea, vomiting, diarrhea and abdominal pain.”

Smollin said some of the patients were parts of cohorts that had consumed the same batch of foraged mushrooms. The largest group was about seven people, he said.

All of the patients were hospitalized, at least briefly. One died. Five remain in hospital care. One has received a liver transplant, and another is on a donation list awaiting a transplant, Smollin said. The patients are 1½ to 56 years old.

Mushroom collectors said death cap mushrooms are more prevalent in parts of California this season than in years past, which could be driving the increase in poisonings.

“Any mushroom has years that it’s prolific and years that it is not. … It’s having a very good season,” said Mike McCurdy, president of the Mycological Society of San Francisco. He added that the death cap was one of the top two species he identified during an organized group hunt for fungi last week, called a foray.

In a news release, Dr. Erica Pan, California’s state public health officer, warned that “because the death cap can easily be mistaken for edible safe mushrooms, we advise the public not to forage for wild mushrooms at all during this high-risk season.”

Dr. Cyrus Rangan, a pediatrician and medical toxicologist with the California Poison Control System, said the “blanket warning” is needed because most people do not have the expertise to identify which mushrooms are safe to eat.

Still, he said, “it’s rare to see a case series like this.”

The California Poison Control System said in a news release that some of the affected patients speak Spanish and might be relying on foraging practices honed outside the United States. Death cap mushrooms look similar to other species in the Amanita genus that are commonly eaten in Central American countries, according to Heather Hallen-Adams, the toxicology chair of the North American Mycological Association. Because death caps are not often found in that region, foragers might not realize the potential risk of lookalikes in California, she said.

Anne Pringle, a professor of mycology at the University of Wisconsin-Madison, said there is a litany of poisoning cases in which people misidentify something because their experience is not relevant to a new region: “That’s a story that comes up over and over again.”

Over the past 10 years, mushroom foraging has boomed in the Bay Area and other parts of the country. At the same time, information resources about mushroom toxicity — reliable and otherwise — have proliferated, as well, including on social media, phone apps and artificial intelligence platforms. Experts said those sources should be viewed with skepticism.

Longtime mushroom hunters maintain that the practice can be done safely. McCurdy, who has collected and identified mushrooms since the 1970s, said he bristled at the broad discouragement of foraging.

“No, that’s ridiculous. … After an incident like this, their first instinct is to say don’t forage,” he said. “Experienced mushroom collectors won’t pay any attention to that.”

But McCurdy suggested that people seek expertise from local mycological societies, which are common in California, and think critically about the sources of information their lives may be relying on.

Pringle and McCurdy both said they have seen phone apps and social media forums misidentify mushrooms.

“I have seen AI-generated guidebooks that are dangerous,” Pringle said.

The death cap is an invasive species that originated in Europe and came to California in the 1930s, most likely with imported nursery trees. The mushroom is usually a few inches tall with white gills, a pale yellow or green cap and often a ring around the base of its stalk.

The species is found across the West Coast and the Eastern Seaboard, as well as in Florida and Texas, according to Hallen-Adams, who is also an associate professor of food science at the University of Nebraska-Lincoln.

In California, it typically grows near oak trees, though occasionally pines, too. The mushroom’s body is typically connected to tree roots and grows in a symbiotic relationship with them.

The toxin in death cap mushrooms, called amatoxin, can damage the kidneys, liver and gastrointestinal tract if it is ingested. It disrupts the transcription of genetic code and the production of proteins, which can lead to cell death.

Hallen-Adams said the U.S. Poison Centers average about 52 calls involving amatoxin each year, but “a lot of things don’t get called into poison centers — take that with a grain of salt.”

Amatoxin poisoning is not the most common type from mushrooms, but it is the most dangerous, she added: “90% of lethal poisonings worldwide are going to be amatoxin.”

It takes remarkably little to sicken a person.

“One cubic centimeter of a mushroom ingested could be a fatal dose,” Hallen-Adams said.

Symptoms of amatoxin poisoning often develop within several hours, then improve before they worsen. There is no standard set of medical interventions that doctors rely on.

“It’s a very difficult mushroom to test for,” Rangan said, and “also very difficult to treat.”

One drug that doctors have leaned on to treat some of the California patients — called silibinin — is still experimental and difficult to obtain.

“All of our silibinin comes from Europe,” Hallen-Adams said.

Death cap mushrooms have continued to grow abundantly since their introduction, and Pringle’s research has shown that the species can reproduce bisexually and unisexually — with a mate or by itself, alone — which gives it an evolutionary advantage.

“If Eve can make more of herself, she doesn’t need Adam,” Pringle said. “One of the things I’m really interested in is how you might stop the invasion, how you might cure a habitat of its death caps. And I have no solutions to offer you at the moment.”
