California’s concerning embrace of a new forest biomass industry

News Feed
Wednesday, March 20, 2024

Gloria Alonso Cruz had only just started working on environmental justice issues at a community organization in Stockton, California when she learned about a proposal to sell wood pellets from the town’s port to overseas energy markets.  Golden State Natural Resources plans to construct two wood pellet plants in Lassen and Tuolumne counties, about 250 miles north of Stockton, with the goal of exporting a million tons a year. While forest-based biomass may sound innocuous, every part of the pellet production chain bears an environmental justice or pollution risk, says Rita Vaughan Frost, forest advocate at Natural Resources Defense Council.  First, trees are logged and stacked on trucks to be driven to processing facilities. There, the wood is turned into small pellets, similar to rabbit food. Then, diesel trucks transport the material hundreds of miles to a shipping facility and export terminal, like the Port of Stockton—where storage poses a fire risk. The pellets are later shipped to markets in Europe and Asia, where they’re burned to create electricity, generating carbon emissions.  Golden State Natural Resource’s proposal would allow it to harvest trees from forests within 100 miles of the two processing plants. This radius includes sixteen national forests in a region known for its critical biodiversity. A 20-year master stewardship agreement established with the U.S. Forest Service will allow the company to harvest from public lands through 2045, when the state is slated to achieve carbon neutrality.  Many might be surprised to learn that burning wood pellets causes more pollution per unit of electricity than coal does, says Dr. Shaye Wolf, the climate science director at the Center for Biological Diversity. “It’s worsening the climate emergency at a time when we’ve got to be rapidly cutting those carbon emissions,” Wolf says.  In Stockton, the threat of logging exports compounds environmental injustices that already exist. State laws don’t prevent companies from building polluting facilities in already-overburdened areas, nor is there any statute or legal framework that forces corporations to consider federal goals of transitioning toward renewable energy sources.   This means there are no federal or state guardrails to protect against the fact that “developers are not accounting for cumulative impacts, [or] the fact that these natural resources are finite,” Cruz says. In fact, Stockton already has a lot of pollution: It ranks in the 90th percentile statewide, according to CalEnviroScreen, an environmental hazard mapping tool. Compared with other cities across California, Stockton’s has some of the highest overall exposure to toxins like ozone, particulate matter, and groundwater threats.  Cruz says that is intentional, noting the communities of color and farmworkers who live and work in the state’s Central Valley have always shouldered the public health consequences that industries leave in their wake. In fact, California funneled public funds to the biomass industry in the 1980s and 1990s to support the construction of factories in low-income communities. Now, the wood pellet biomass industry and Golden State Natural Resources are poised to make the situation worse. In 2015, the state approved a new law that requires polluting corporations, like the wood pellet industry, to pay for environmental justice projects in disadvantaged cities like Stockon, but advocates like Cruz argue that corporations shouldn’t be allowed to pollute in the first place. Across the state, at least four active biomass plants are in census tracts that face the worst pollution burden.  Looking at how the biomass industry currently operates in the Southeastern United States heightens residents’ worries. Companies there have a track record of preying on overburdened, under-resourced communities, says Vaughan Frost. In the South, pellet mills are 50% more likely to be placed in communities of color that fall below the state poverty line. Although the industry likes to talk about providing jobs, in one North Carolina community, the poverty rate actually increased after a wood pellet production plant began operations.  Wherever pellet mills take root, pollution soon follows. A powerful odor, akin to plastic burning in a campfire, often emanates from these processing facilities. Heather Hillaker, an attorney with the Southern Environmental Law Center, says that processing the wood creates volatile organic compounds, which mix with other pollutants to create ground level ozone and smog. Processing facilities also release toxins like formaldehyde, methanol, and acrolein, substances that can cause cancer even in small doses.  Hillaker warns that federal standards established by the Clean Air Act don’t take into consideration the multiple forms of pollution that overburdened communities face, she says.  “I’ve not really seen the pellet industry directly address, in any kind of meaningful way, the environmental justice impacts of their operations in the South,” Hillaker says. She explains they often argue “We are complying with our permits and therefore we’re not causing any harm.” But she says, “That’s not an accurate representation of what’s actually happening in these local communities.”  Vaughan Frost is concerned that Golden State Natural Resources will similarly undermine the health and wellbeing of California communities.  Vaughan Frost believes the industry is “exploiting the state’s traumatic experience of catastrophic wildfires to sell their plan.” The company claims that cutting down forests will provide less fuel for wildfires—a claim that the state of California has historically parroted. Many scientists disagree. One recent study found that in fire-prone western states, emissions related to broad-scale thinning biomass harvest were five times greater than those related to wildfire. California also has a history of lumping in wood pellet biomass as a “renewable” energy source, which critics say obfuscates the compounding climate threats of the industry. She says these claims—that logging can prevent wildfires and create renewable energy— are a distraction from legitimate wildfire prevention strategies, like home hardening and vegetation management.  Advocates worry that once the forest is gone, recovery will be difficult. The wood pellet industry will soon be making incursions throughout the Sierra Nevadas, a much-loved mountain range that regularly draws outdoor tourists. Though the industry pledges to replant what they log, as climate change intensifies, there’s no guarantee monoculture saplings will be able to provide the same ecosystem services that the logged forest once did.  With abundant wind and solar energy available, Vaughan Frost says, “We do not need to sacrifice California forests and communities for this.” NRDC (Natural Resources Defense Council) is an international nonprofit environmental organization with more than 3 million members and online activists.

The 'World's Loneliest Plant' Could Soon Find a Mate With a Little Help From A.I.

The only known wild Wood's cycad was discovered in 1895, and it has since been cloned into many male trees. Now, researchers are scouring a forest in South Africa for an elusive female specimen

Project leader Laura Cinti visited the Wood's cycad at Royal Botanic Gardens, Kew, in London. C-LAB The world’s loneliest plant could soon be a little less lonely—and possibly even find a mate—with the help of scientists using artificial intelligence (A.I.). Their new effort could help identify an elusive female specimen of the Wood’s cycad (Encephalartos woodii), a rare and unusual member of a plant family that predates the dinosaurs. The only known Wood’s cycad plants in existence are male, and these can be cloned to produce additional male specimens. But to reproduce naturally—and to keep the threatened species from going extinct—the Wood’s cycad needs separate male and female plants. Discovering a female Wood’s cycad, however, is like finding a needle in a haystack. So, researchers are turning to A.I. for help. They’re using an image-recognition tool to sift through thousands of images captured by drones in 2022 and 2024. The unmanned aerial vehicles flew over a 195-acre swath—about the size of 148 football fields—of the Ngoye Forest in South Africa, snapping pictures in five wavelengths as they went. Researchers trained the tool, a computer vision model called YOLOv8, to pick out Wood’s cycads from other trees in the canopy. So far, they haven’t had any luck finding a female, but they’re planning to continue refining the image-recognition model. “I was very inspired by the story of the E. woodii, it mirrors a classic tale of unrequited love,” says project leader Laura Cinti, an artist and biologist at the University of Southampton and the co-founder of C-LAB, a research-based art collective, in a statement. “I’m hopeful there is a female out there somewhere, after all there must have been at one time. It would be amazing to bring this plant so close to extinction back through natural reproduction.” Romantic as it may sound, finding a Wood’s cycad in the wild will undoubtedly be challenging. That’s because only a single specimen has ever been seen in nature. In 1895, South African botanist John Medley Wood came upon a solitary male Wood’s cycad in Ngoye Forest. The plant was named in his honor. Wood looked for other examples of the plant, but he never found any. Botanists removed offshoots and stems from the lone cycad in the forest, then propagated them back at their botanic gardens, creating a population of male plants. One specimen arrived at Royal Botanic Gardens, Kew, in London in 1899 and has lived there alone ever since—for 125 years. The cloning efforts can “keep going, but it’s like ­Waiting for Godot,” Cinti tells the London Times’ Tom Whipple, referring to Samuel Beckett’s 1952 play. “They remain in this permanent vegetative state. A male without a female, this is a potent story.” In 1916, government forestry officials removed the lone male Wood’s cycad from the wild and transferred it to an enclosure in Pretoria, South Africa, for safekeeping, as Cinti writes in the Conversation. But it died a few years later, per the project website. The Wood’s cycad is considered extinct in the wild, and clones of the lonely male are often kept under lock and key to protect them from poachers. The exact number of clones is unknown, but Royal Botanic Gardens, Kew, estimates around 110 exist, while the South African National Biodiversity Institute writes there could be as many as 500. Cycads, as a group, have been around a long time. The first ones developed around 300 million years ago, roughly 70 million years before the emergence of dinosaurs. At that time, these plants were abundant and thriving. But today, they’re some of the most threatened species on Earth. Cycads look similar to palms, thanks to their thick trunks and large, umbrella-shaped crowns of leaves. But they’re part of an entirely separate group that includes ginkgos and conifers. All individual cycads are either male or female, but they are indistinguishable until they mature—a process that can take 10 to 20 years. They reproduce via their cones: Male cones—which are longer and narrower—produce pollen, which weevils then carry to the rounder, wider female cones that contain seeds. Once the seeds are fertilized, they can be spread by birds, bats, insects and other seed carriers, as NPR’s Robert Krulwich reported in 2011. Paleontologists believe that hungry dinosaurs may have also helped cycads proliferate. “The creatures might have dropped embryonic cycads in new places, complete with some fresh fertilizer to aid their growth,” as Riley Black wrote for Smithsonian magazine in 2022. If researchers ever locate a female Wood’s cycad, they will likely remove it from the wild so they can closely monitor and manage its reproduction, per Live Science’s Richard Pallardy. But, for now, they’re still searching. The 195 acres they’ve photographed so far represent just a fraction of the total 10,000-acre Ngoye Forest. So while the search hasn’t turned up any Wood’s cycads yet, they’re hopeful a female is still out there, just waiting to be found. In addition, botanists are trying to keep the species alive by crossing a Wood’s cycad with a close relative, the natal giant cycad (Encephalartos natalensis), per Royal Botanic Gardens, Kew. If the project is successful, it would produce a female “very closely resembling” a Wood’s cycad, per the gardens. Another project, also led by Cinti, is exploring whether chemical or physiological manipulation could change the sex of the Wood’s cycad. “There have been reports of sex change in other cycad species due to sudden environmental changes such as temperature, so we are hopeful we can induce sex change in the E. woodii too,” she says in the statement.

Balancing economic development with natural resources protection

From scallop fishing in New Bedford to deforestation in the tropics, “our goal is to get some empirical traction on the problem,” says PhD student Aaron Berman.

It’s one of the paradoxes of economic development: Many countries currently offer large subsidies to their industrial fishing fleets, even though the harms of overfishing are well-known. Governments might be willing to end this practice, if they saw that its costs outweighed its benefits. But each country, acting individually, faces an incentive to keep subsidies in place.This trap evokes the classic “tragedy of the commons” that economists have studied for generations. But despite the familiarity of the problem in theory, they don’t yet have a lot of hard evidence to offer policymakers about solutions, especially on a global scale. PhD student Aaron Berman is working on a set of projects that may change that.“Our goal is to get some empirical traction on the problem,” he says.Berman and his collaborators are combining a variety of datasets — not only economic data but also projections from ecological models — to identify how these subsidies are impacting fish stocks. They also hope to determine whether countries might benefit instead from sustainability measures to help rebuild fisheries, say through new trade arrangements or other international policy agreements.As a fourth-year doctoral candidate in MIT’s Department of Economics, Berman has a variety of other research projects underway as well, all connected by the central question of how to balance economic development with the pressure it puts on the environment and natural resources. While his study of fishing subsidies is global in scope, other projects are distinctly local: He is studying air pollution generated by road infrastructure in Pakistan, groundwater irrigation in Texas, the scallop fishing industry in New England, and industrial carbon-reduction measures in Turkey. For all of these projects, Berman and his collaborators are bringing data and models from many fields of science to bear on economic questions, from seafloor images taken by NOAA to atmospheric models of pollution dispersion.“One thing I find really exciting and joyful about the work I’m doing in environmental economics is that all of these projects involve some kind of crossover into the natural sciences,” he says.Several of Berman’s projects are so ambitious that he hopes to continue working on them even after completing his PhD. He acknowledges that keeping so many irons in the fire is a lot of work, but says he finds motivation in the knowledge that his research could shape policy and benefit society in a concrete way.“Something that MIT has really instilled in me is the value of going into the field and learning about how the research you’re doing connects to real-world issues,” he says. “You want your findings as a researcher to ultimately be useful to someone.”Testing the watersThe son of two public school teachers, Berman grew up in Maryland and then attended Yale University, where he majored in global affairs as an undergraduate, then stayed to get his master’s in public health, concentrating on global health in both programs.A pivotal moment came while taking an undergraduate class in development economics. “That class helped me realize the same questions I cared a lot about from a public health standpoint were also being studied by economists using very rigorous methods,” Berman says. “Economics has a lot to say about very pressing societal issues.”After reading the work of MIT economists and Nobel laureates Esther Duflo and Abhijit Banerjee in that same class, he decided to pivot and “test the waters of economics a little bit more seriously.” The professor teaching that class also played an important role, by encouraging Berman to pursue a predoctoral research position as a first step toward a graduate degree in economics.Following that advice, Berman landed at the Harvard Kennedy School’s Evidence for Policy Design, a research initiative seeking to foster economic development by improving the policy design process. His time with this organization included five months in Jakarta, Indonesia, where he collaborated with professors Rema Hanna and Ben Olken — of Harvard and MIT, respectively — on a portfolio of projects focused on analyzing social protection and poverty alleviation.The work, which included working closely with government partners, “required me to think creatively about how to talk about economics research to several different types of audiences,” he says. “This also gave me experience thinking about the intersection between what is academically interesting and what is a policy priority.”The experience also gave him the skills and confidence to apply to the economics PhD program at MIT.(Re)discovering teachingAs an economist, Berman is now channeling his interests in global affairs to exploring the relationship between economic development and protecting the natural environment. (He’s aided by an affinity for languages — he speaks five, with varying degrees of proficiency, in addition to English: Mandarin, Cantonese, Spanish, Portuguese, and Indonesian.) His interest in natural resource governance was piqued while co-authoring a paper on the economic drivers of climate-altering tropical deforestation.The review article, written alongside Olken and two professors from the London School of Economics, explored questions such as “What does the current state of the evidence tell us about what causes deforestation in the tropics, and what further evidence is needed?” and “What are the economic barriers to implementing policies to prevent deforestation?” — the kinds of questions he seeks to answer broadly in his ongoing dissertation work.“I gained an appreciation for the importance and complexity of natural resource governance, both in developing and developed countries,” he says. “It really was a launching point for a lot of the things that I'm doing now.”These days, when not doing research, Berman can be found playing on MIT’s club tennis team or working as a teaching assistant, which he particularly enjoys. He’s ever mindful of the Yale professor whose encouragement shaped his own path, and he hopes that he can pay that forward in his own teaching roles.“The fact that he saw I had the ability to make this transition and encouraged me to take a leap of faith is really meaningful to me. I would like to be able to do that for others,” Berman says.His interest in teaching also connects him further with his family: His father is a middle school science teacher and mother is a paraeducator for students with special needs. He says they’ve encouraged him throughout his academic journey, even though they initially didn’t know much about what a PhD in economics entailed. Berman jokes that the most common question people ask economists is what stocks they should invest in, and his family was no exception.“But they’ve always been very excited to hear about the kinds of things I’m working on and very supportive,” he says. “It’s been a really amazing learning experience thus far,” Berman says about his doctoral program. “One of the coolest parts of economics research is to have a sense that you’re tangibly doing something that’s going to have an impact in the world.”

Saving Oregon’s kelp forests: do’s and don’ts for Oregonians who want to help

While there’s no simple solution to restore kelp forests, Oregonians who would like to help should know a few rules.

A bull kelp’s air-filled bladder floats up to the surface off the Oregon coast, its fronds or blades providing a perfect hiding place for tiny baby fish. Oregon Department of Fish and Wildlife Marine Reserves ProgramWhile there’s no simple solution to restore kelp forests, Oregonians who would like to help should consider the following:Don’t go out diving or snorkeling alone because Oregon’s coastal waters are very cold and conditions are harsh. Seasoned SCUBA divers who want to participate in kelp forest restoration, including urchin removal, can contact the Oregon Kelp Alliance. The group works with Reef Check, a California-based nonprofit, to train citizen science divers in underwater restoration and survey techniques.Don’t collect sunflower sea stars – it is illegal. Instead, report sightings on seastarwasting.org if the stars are diseased, or report healthy star sightings on iNaturalist or contact one of Oregon’s sea star researchers directly.Don’t remove or smash purple sea urchins. A state-issued scientific take permit is required to remove purple urchins at kelp restoration sites and those permits are not available to the general public.It’s OK to collect a handful of purple urchins for personal use, including to make sea urchin sushi, uni butter or uni sauce. Harvesting up to 10 urchins per day requires a recreational shellfish permit. Urchins for personal use cannot be removed from designated marine reserves, marine gardens and other conservation areas.Harvesting kelp for personal consumption that’s washed up on the beach is allowed year-round, while harvesting live seaweed is allowed only March through June, except in marine reserves and other protected habitats, where it’s not allowed. No license is required but collection is limited to one gallon per day and up to three gallons per calendar year.— Gosia Wozniacka covers environmental justice, climate change, the clean energy transition and other environmental issues.

Oregon’s underwater forests are vanishing. Can they be saved?

As marine heat waves wreak havoc on Oregon’s ocean ecosystems, the collapse of kelp forests could prove catastrophic to marine life, fisheries and tribes.

On a chilly May morning at a sandy beach 15 miles southwest of Coos Bay, marine ecologist Sara Hamilton poured hot water from a thermos into her thick wetsuit, neoprene dive boots and gloves. Snorkeling mask and fins in hand, she made her way toward the jutting headland of Cape Arago State Park, across slippery rocks draped in seaweed, mussels and barnacles and crevices teeming with green sea anemones.Hamilton eased herself into the ocean, a frigid 49 degrees that day, followed by several colleagues who braced themselves on surf-drenched rocks. But the waves crashed too high, sending the team into shallower waters before they floated and dove down.A lush, towering kelp forest had sprung up under the waves in this cove in each of the past three summers, providing refuge to juvenile rockfish and salmon, shrimp, whales and countless other creatures. But it was unclear if it would regrow this year or become the latest casualty of an upended marine ecosystem that could herald the future impact of global warming on Oregon’s coast.For millennia, underwater forests of seaweed or large brown algae stretched from the seafloor to the ocean’s surface, forming canopies, much like trees, and providing food, shelter and hunting grounds to countless animals. Bull kelp, the predominant species found along the southern third of Oregon shores, is one of the world’s fastest growers – rising at a rate of up to 10 inches per day and reaching heights of up to about 100 feet, establishing itself as the sequoia of the seas. Kelp has helped protect the coastline from storms and supported local fisheries, tribal fishing and cultural practices.But over the past decade, according to new data, Oregon lost more than two-thirds of that kelp canopy.Kelp’s troubles on the West Coast started in 2013 when a mysterious illness began to decimate sunflower sea stars, the sole predators of purple sea urchins in Oregon. In turn, the purple urchins — small, spiky orbs that are native to the coast but previously dwelled in the crevices of tide pools, passively feeding on pieces of drifting kelp — had a bonanza population spurt.Purple urchins cover the sea floor at Cape Arago State Park on May 24, 2024. The urchins, whose population growth was exacerbated by a marine heat wave, have eaten most of Oregon’s kelp forests.  Gosia Wozniacka / The OregonianWarmer water didn’t cause the stars’ disease, but scientists say the starfish died faster because of it. They have concluded that the Blob, an extreme heat wave in the Pacific Ocean that in 2014 raised temperatures between 4 and 10 degrees above average and lasted for more than 700 days, exacerbated both the star die-off and the urchin explosion. Without sunflower sea stars – considered the largest and fastest of the starfish species, able to grow up to 24 arms and easily outrun prey – hordes of purples took over underwater forests. They overgrazed the kelp, forming “urchin barrens,” lifeless zones covered with hungry purple urchins and not much else.The problem was not unique to the Pacific Ocean; purple urchins overran kelp forests across the globe, from Tasmania to Norway. On the West Coast, a collapse was first identified in northern California in 2019 when a study chronicled the abrupt decline of kelp there by more than 90% in 2014. Similar warning signs emerged in southern Oregon: the wads of snake-like tangles that had once washed up on beaches were becoming scarce and the dense floating mats of kelp along the shores had nearly vanished – and with them, the fish and animals that had once lived and hunted there.Despite the red flags, action to probe the extent of kelp’s loss and to stave it off has been slow. Oregon’s craggy, exposed shoreline and murky waters meant few divers had been taking stock of underwater conditions. And because the state doesn’t allow commercial harvesting of kelp, wildlife officials had neither the mandate nor the funding to regularly survey or monitor the situation.In the void, a nonprofit launched in 2019 in the small coastal town of Port Orford, about 60 miles north of the California border, bringing together local fishermen, researchers, tribal members, university students, recreational and commercial divers. The Oregon Kelp Alliance had a singular focus: to sound the alarm and take immediate action to protect Oregon’s underwater jungles.Tom Calvanese, the founder and director of the Oregon Kelp Alliance, helps lower a boat into the ocean at the Port Orford port in southern Oregon. Calvanese has been at the forefront of kelp restoration efforts in Oregon.  Gosia Wozniacka / The OregonianPreviously, “the ocean felt alive, smelled alive and looked alive. The kelp was doing its job as a foundation species, supporting this vibrant ecosystem. The water was clearer. There were a lot of fish, marine mammals, birds and whales, right there, all around you,” said the group’s founder, Tom Calvanese, a fisheries scientist and former commercial urchin diver.“Fast forward to now,” he added, “the ocean without kelp doesn’t feel vibrant anymore, it doesn’t have much activity, much life.”Over the past five years, the Kelp Alliance has gained momentum, expanding up and down the coast. It’s secured more than $4 million in federal, state and private funding to conduct, in partnership with the state, a coast-wide survey of kelp and launch several scientific research and restoration projects aimed at saving kelp habitat, controlling purple urchins and bringing back sunflower sea stars. Later this summer, the group will publish a kelp status report and a comprehensive restoration plan that aims to rehabilitate Oregon’s underwater forests, although similar efforts in California so far have yielded only modest success.The soon-to-be-released report, shared early with The Oregonian/OregonLive, quantifies for the first time the amount of damage the state’s kelp forests sustained between 2010 and 2022.In all, more than two-thirds of Oregon’s kelp canopy disappeared from the southern shores. That’s nearly 900 acres, or the equivalent of 680 football fields.Floating kelp canopy observed in ODFW aerial surveys in 2010 and 2022 at three major kelp-bearing regions on the Oregon coast. Orford Reef (top, off Cape Blanco) historically held the largest kelp bed in the state by far, and has seen the most dramatic kelp decline. Meanwhile, Redfish Rocks (middle, near Port Orford) and Rogue Reef (bottom, off Gold Beach) both saw localized kelp losses that were largely balanced by a shifting kelp distribution.Oregon Department of Fish and WildlifeThe repercussions of those massive losses are just starting to emerge. The state’s commercial red sea urchin harvest is down by half from a decade ago. The recreational red abalone fishery permanently closed in December. And recreational nearshore fishing has dwindled on the southern coast.Researchers with the Kelp Alliance have estimated, based on a global assessment of kelp ecosystem values, that the 900 acres of lost kelp canopy is costing Oregon $23 million to $53 million every year. This includes the value of shrinking local fisheries as well as the ocean’s lessened ability to absorb carbon dioxide from the atmosphere. Underwater kelp forests are key to combating climate change – they can sequester up to 20 times more carbon per acre than land forests.How rising temperatures will impact kelp moving forward is unclear, although it typically does better in cooler waters that provide more nutrients. The state’s coastal surface waters warmed an average of half a degree per decade from the mid-20th century to the 2000s, according to the most recent state-funded analysis published in 2010. But the alliance’s report concludes that, unlike in other parts of the world, long-term ocean warming is likely not a cause of kelp’s decline in Oregon even as short-term heat waves played a significant role.While kelp is susceptible to heat – it experiences decreased growth and reproductive success when temperatures regularly reach 61 degrees and can die or fail to reproduce when the water warms past about 64 degrees – those thresholds have been rarely reached along Oregon’s southern shores. In fact, researchers noted that surface water temperatures at two locations, off Port Orford and at Charleston, near Coos Bay, have declined very slightly over the past 30 years.Complicating matters, a few areas, including Cape Arago State Park near Coos Bay, saw gains in kelp cover for reasons researchers don’t yet understand.Hamilton, the marine ecologist, has monitored kelp at Cape Arago for the past three years with a drone and by diving or snorkeling there about a dozen times. Every year, the underwater forest has regrown, making it one of Oregon’s bright spot outliers, with a 25% increase in canopy cover.She’s cautiously optimistic that, despite an abundance of purple urchins already on scene, it will come back this summer.Snorkeling through cloudy water at the cove this spring, the research team spotted signs of hope, anchored to the seabed.Hamilton broke the surface and yelled: “Baby kelp!”But she remains worried about the future.“There’s a theory known as tipping points. If you push a system closer and closer to a point where all of a sudden the urchins take over, they can quickly switch the kelp forest to an urchin barren,” Hamilton said after the snorkeling excursion. “We have these sites that still seem relatively healthy. We don’t know if they’re close to tipping. We don’t know if they can sustain those populations of urchins long-term. It fuels our sense of urgency and anxiety.”FEELING KELP’S LOSSThe disappearance of kelp – amid the rise and dominance of purple urchins – is being felt all along Oregon’s southern shores.This spring in Port Orford, Calvanese, the Kelp Alliance founder, and his friend Dave Lacey, a boat captain, steered a small boat out of the tiny port toward a rocky headland known as The Heads. They circled just below at Nellies Cove, a sheltered bay.Tom Calvanese, the Kelp Alliance director, and his friend Dave Lacey, a boat captain, steer a boat on May 25, 2024, out of Port Orford in southern Oregon toward Nellies Cove. The picturesque cove has become a wasteland of purple urchins.  Gosia Wozniacka / The OregonianThe cove is ground zero for Oregon’s kelp restoration efforts. It’s where Calvanese, Lacey and others first began to notice signs of dramatic change.The two men, both transplants from the East Coast, recalled paddling or kayaking together just past the breakwater with their fishing poles to where a dense mat of kelp encircled the shores. Lacey, the head of a local tour company, would bring groups of recreational fishing enthusiasts. They would park their kayaks right on the edge of the kelp forest and fish over it.“We never got skunked here. We always caught fish, always,” Calvanese said.Then, about six years ago, the kelp canopy disappeared – and with it, the fish at Nellies Cove.“It got so bad, we stopped doing kayak fishing tours,” Lacey said. “We used to pull in about $10,000 every summer. Now that’s totally gone. We just gave up on it. I didn’t want to take people’s money and not catch any fish.”Calvanese, who manages Oregon State University’s field station at Port Orford, also began fielding calls from commercial urchin divers alarmed by kelp declines on nearby reefs. They took him by surprise. He had worked for an urchin diving crew while finishing his graduate degree and had seen first-hand the thick forests stretching for hundreds of acres under the waves.He realized the stakes were high. Port Orford, population 1,149, is dependent on fishing. With kelp forests dwindling, both the commercial nearshore fishery – rockfish, cabezon and greenling – and the red urchin fishery could be threatened, not to mention recreational fishing and tourism.Calvanese wanted to see the underwater changes for himself, so he dove in Nellies Cove. What he found shocked him and brought tears to his eyes, he said. The entire sea bottom was covered in purple urchins actively foraging for food. Where a thriving kelp forest had once grown, bountiful with juvenile and adult fish, he now couldn’t spot a single kelp.The fish, too, were mostly gone.A few hundred yards from that spot in Nellies Cove, commercial urchin diver Tom Butterbaugh anchored his boat, the F/V Good News, surveying the area this spring for red urchins to harvest.Urchin diving in Oregon is a dangerous job, and Butterbaugh has been searching for them under water for 24 years. Unlike the small and skinny purple urchins that have no commercial value, red urchins are harvested throughout the world for their roe — also called uni — which is considered a delicacy, especially in Japan.The business was once lucrative. Now, it’s less so. Most of the red urchins in Oregon are either gone or their roe isn’t well developed because they have to compete for food with the masses of purple urchins.Butterbaugh remembers good kelp years and bad kelp years, but it’s never been as bad as it is now, he said.He estimates he has lost over 90% of red urchin picking territory in recent years, most of it at nearby Orford Reef – the hardest-hit area for kelp decline – where he had typically harvested for six months annually.“The feeling of loss, the frustration, the helplessness when we can’t get the urchins is constantly there,” he said. “‘Where are we going to go? We already went there.’ Our [harvest] counts are getting lower and lower. Maybe this will be the year that the kelp comes back. We thought it was going to come back last year. And look at Depoe Bay, the kelp is amazing, but the urchins are skinny anyway.”The only reason he’s still in business is because the domestic market for red urchins has grown. A decade ago, he picked urchins for 50 to 80 cents per pound. Now, depending on the season and whether there’s competition from divers in Mexico or Chile, the price is up at $2 to $4.“It’s been thin ice for urchin divers,” Butterbaugh said. “The only thing keeping us afloat are the higher prices. If we lost market value, we’d go out of business.”From left, black rockfish, red urchins, sunflower sea star and red abalone.  Photos courtesy Oregon Department of Fish and Wildlife Marine Reserves ProgramConcern is also growing over the future of the commercial groundfish industry in Port Orford. Kelp forests act as nurseries for juvenile rockfish and other groundfish – providing shelter, food and a place to grow – so the drastic decline of kelp beds is bound to have an impact, said Port of Port Orford Commission president Aaron Ashdown. Although local fishermen have yet to see changes in fish availability, he said, that’s likely because rockfish are some of the longest-living fish.“We might not see the negative effects of this kelp die-off until a decade or two goes by because of how long it takes for these fish to grow up,” Ashdown said. “But by then, we could see the collapse of certain species.”For the Coquille Indian Tribe, too, the decline of underwater forests has been wrenching, spelling the disappearance of tribal foods and practices, said Shelley Estes, an enrolled member of the tribe, which has inhabited Oregon’s southwestern coast for thousands of years.“Our elders said the kelp was our ‘canoe superhighway,’” said Estes, who is on the tribe’s resiliency climate task force. “Our people ran canoes up and down the coastline. That’s where we felt safe. Kelp protected us. It absorbed the shocks of the waves coming onto the shore.”One of the early victims of the disappearing kelp is red abalone, a large ocean snail that grazes on kelp and is a traditional source of nourishment and spiritual protection for the tribe. Abalone shells are also used in smudging – cleansing rituals that use burning herbs to clear out negative energies – and to make tribal regalia.Without kelp, the abalone, whose populations were already in decline prior to kelp’s collapse, have starved. The tribe can no longer harvest them and must purchase their shells on Amazon.“As a tribal member, I’m alarmed,” Estes said.PATH TO RESTORATIONRestoring kelp along Oregon’s southern shoreline may require an assortment of strategies, including, crucially, removing most of the purple urchin – somehow.A healthy bull kelp forest swayed underwater in August 2021 at Redfish Rocks, one of Oregon’s five marine reserves just south of Port Orford. The tree-like algae float up to the surface buoyed by air-filled bladders, their fronds or blades forming a thick canopy.  Brandon Cole / Special to The OregonianThe Kelp Alliance initially focused on hand removing and composting purple urchins or smashing them with hammers on the seabed – under a permit from the state – at sites including Nellies Cove, Macklyn Cove in Brookings and Haystack Rock in Pacific City. But those efforts, as in California, have had limited impact thus far, due in part to limited funding that paid for only short-term removal actions.One challenge is that purple urchins can persist in a hungry zombie state for well over a year, easily outlasting the annual cycle of bull kelp and lying in wait to devour baby algae before it has a chance to regrow. As a result, scientists say, it’s extremely difficult to flip barrens back into kelp ecosystems – it requires continually removing most if not all urchins in an area. Short of that, studies and surveys have shown that urchin removal can be effective when it happens at larger, semi-discrete sites or focuses on barrens surrounded by healthy kelp.Restoring kelp forests coast-wide by removing urchins by hand is clearly not feasible.Case in point: At Orford Reef – where Butterbaugh traditionally dove for red urchins – state biologists in 2019 documented 350 million purple urchins sitting on the seabed, a 10,000% increase over a five year period. The reef, once the state’s largest underwater kelp forest, spanning about 1,655 acres or just under half the size of the city of Astoria, saw a 95% decline in kelp, the largest in Oregon, according to the new data.“We realized we could not smash our way out of this crisis,” said Calvanese, the Kelp Alliance’s founder.The group is now launching a new $2.5 million restoration initiative that ties targeted urchin removal with kelp revegetation. Divers in Oregon will remove urchins at six sites along the coast and then “seed” kelp via spore bags and other cultivation methods. The sites include not only urchin barrens such as Nellies Cove but also areas that have abundant kelp canopy yet are overrun with urchins, such as Cape Arago.Separately, the group is mounting a kelp mariculture project in the waters around Port Orford. It will grow bull kelp on vertical mooring lines off the ocean bottom and out of reach of hungry urchins. The kelp will be used to make animal feed or fertilizer – a boost to the local economy – and spores will be saved for the kelp revegetation at restoration sites. The group is also working with local seaweed farms to collect purple urchins to fatten them up in land-based tanks with the hope to make them commercially viable.Ultimately, said Calvanese, restoration can stave off the complete disappearance of kelp along the West Coast by protecting a network of small sites that can maintain kelp’s genetic diversity and eventually repopulate urchin barrens.“If we can restore and maintain these oases where we continue to produce kelp spores then we have a chance to regrow from there,” he said. “We can also protect the remaining kelp we still have and not just watch it shrivel up.”MORE: Does kelp restoration work?But to make kelp’s comeback viable at scale, Calvanese and others are betting big on returning the sunflower sea stars – purple urchins’ only predator in the state – to the ocean.Scott Groth, a marine scientist with the Oregon Department of Fish and Wildlife, holds a sunflower sea star off the Oregon coast near Port Orford. The photo was taken before a mysterious wasting disease wiped out the population of the sea stars in Oregon beginning in 2013.  Scott Groth / Oregon Department of Fish and WildlifeMarine ecologists Aaron Galloway and Sarah Gravem, with the University of Oregon and Oregon State University, have been able to show that the sunflower sea stars could potentially regulate purple sea urchin populations and, as a result, restore and maintain healthy kelp forests.Their study published last year indicates that sunflower sea stars don’t discriminate between fully grown healthy urchins and starved, nutritionally poor urchins similar to those that dwell in urchin barrens. In fact, during experiments the sea stars ate more skinny, hungry urchins than healthy ones, likely because it takes a shorter amount of time to digest them, Galloway said.Modeling also showed that, at the densities of sea stars before the wasting disease, there were enough stars to stop urchins from turning kelp forests into barrens.With those results in mind, the scientists, who are both members of the Kelp Alliance, are working toward a captive breeding program in Oregon, with the end-goal being reintroduction to the wild. That reality is now a step closer as Oregon has seen an increase in the sightings of sunflower sea stars, meaning researchers can start collecting them for local experiments and breeding. Earlier this year, Galloway secured approval for a permit to collect 20 in Oregon waters to launch the endeavors. He’s working closely with a lab in Washington that was the first to successfully breed the animals.Eventually, Galloway said, he hopes to breed and release thousands of sunflower sea stars into Oregon waters and see how they behave in urchin barrens. It’s unclear whether this will work, he admits. Though several research centers and aquariums around the U.S. are now racing to breed the stars, which the federal government last year proposed to list as threatened under the Endangered Species Act, no one has attempted such a release thus far.“It’s a dream for us,” he said. “If we put a bunch of them at a reef or declining kelp forest, will it cause a recovery? Will the stars eat the urchins or will they just leave and go somewhere else?”In September 2023, a drone captured a thick bull kelp canopy growing just off of Cape Foulweather’s Otter Crest State Scenic Viewpoint. The cape, just south of Depoe Bay, was one of the few areas on Oregon’s coast that saw an increase in kelp last year.  Sara Hamilton / Oregon Kelp Alliance.Because that’s a long-term endeavor, Gravem said, the state needs to urgently step up to regularly monitor, manage and restore kelp forests, similar to how it manages land-based forests, grasslands and estuaries.“For a long time, we’ve been hesitant to intervene in the ocean. It’s so big and we thought that it would rebound if we just left it alone,” Gravem said. “But it’s becoming increasingly clear that it’s not rebounding on its own. If anything, it’s getting worse because of climate change. So we need to … start helping it along.”— Gosia Wozniacka covers environmental justice, climate change, the clean energy transition and other environmental issues.

The Environmental Prosecutor’s Office and the Prosecutor’s Office for Probity, Transparency, and Anticorruption reported that five people have been arrested in connection with an illegal logging investigation in the Gandoca Manzanillo Wildlife Refuge, located in the Talamanca canton. The Public Prosecutor’s Office stated that the events under investigation took place on a farm owned by Playa Manzanillo, S.A., in Talamanca, where irregularities were apparently found in the issuance of logging permits. “It is believed that they sought to change the land use in the forest and wetland areas, presumably to develop urban infrastructure,” explained the Prosecutor’s Office. Meanwhile, the five individuals remain in custody pending a hearing for precautionary measures. “After the arrests, the Public Prosecutor’s Office gathered statements from the accused and presented them to the Criminal Court of Finance and Public Function,” stated the Prosecutor’s Office on Wednesday morning. The investigation centers on case number 24-00003-0611-PE and involves alleged crimes including prevarication, influence against the Public Treasury, change of land use, ideological falsehood, and use of false documents. Residents of Puerto Viejo and Manzanillo have reported constant sightings of trucks loaded with lumber. Videos published by the organization “Bloque Verde” depict these trucks, alongside markings indicating trees slated for cutting. These organizations denouce environmental destruction that could be irreversible. A few months ago, Congressman Ariel Robles had requested an investigation into officials who authorized tree logging in the forested area of Manzanillo. “It is surprising that logging was authorized and facilitated by the Costa Rican State itself with such limited oversight from the State, institutions, the Ministry of Environment, and the Municipality of Talamanca. This is truly shameful. Therefore, we urge the Attorney General’s Office to conduct thorough investigations,” he emphasized. Franz Tattenbach, Minister of Environment, confirmed that permission had been granted for tree logging in the area. The Minister has been called to appear before the Legislative Assembly to address this matter.
