If you’re inclined to be seasick or reluctant to get out on the ocean, another great way to see whales is to get onto a coastal clifftop somewhere. The higher you are, the better.

As that heat builds up, it’s having devastating consequences.\u003c/p>\n\u003cp>“When I heard the numbers of birds being killed in California and Oregon and Washington and many areas of Alaska, as that unfolded, it was biblical to me,” said John Piatt, a biologist with the U.S. Geological Survey who was the lead author of the new paper on the bird deaths and has been studying common murres for 40 years.\u003c/p>\n\u003cp>“This bird doesn’t fail unless there aren’t enough high density patches of food to serve their high demand needs. And that’s rare,” Piatt said.\u003c/p>\n\u003cp>\u003cstrong>The Death Toll Grows\u003c/strong>\u003c/p>\n\u003cp>So what happened?\u003c/p>\n\u003cp>As reports came in from up and down the Pacific coast, Piatt was perplexed. Common murres are known for their ability to adapt. “Murres are the ultimate predator—they’re extremely well adapted, they can dive to 200 meters, and they live on the Continental Shelf,” he said. “Anywhere along there is their domain. And they’re the fastest flying sea bird.”\u003c/p>\n\u003cp>Yet murres were washing in with the tides—sometimes 10 birds at a time, sometimes 100.\u003c/p>\n\u003cp>After Irons’ discovery on New Year’s Day, everything changed, said Julia Parrish, a biologist at the University of Washington who leads the Coastal Observation and Seabird Survey Team and was a co-author of the study. Federal agencies started to get involved and were able to fly along the coastline and send more people to conduct surveys.\u003cimg loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-1955899 alignleft\" src=\"https://ww2.kqed.org/app/uploads/sites/35/2020/01/Common-Murre-Populations.png\" alt=\"\" width=\"529\" height=\"770\" srcset=\"https://cdn.kqed.org/wp-content/uploads/sites/35/2020/01/Common-Murre-Populations.png 529w, https://cdn.kqed.org/wp-content/uploads/sites/35/2020/01/Common-Murre-Populations-160x233.png 160w\" sizes=\"(max-width: 529px) 100vw, 529px\">\u003c/p>\n\u003cp>Surveys in the Gulf of Alaska conducted by the Interior Department turned up more than 20,000 dead murres, and the public reported 21,435 more to the department.\u003c/p>\n\u003cp>The scientists reached out to bird and rehabilitation centers from southern California to Alaska and found that, out of 66 that responded, 37 reported receiving injured or dead murres—a total of 3,365 birds. The body count ticked higher.\u003c/p>\n\u003cp>\u003cstrong>The Investigation\u003c/strong>\u003c/p>\n\u003cp>The first thing the scientists needed to know was whether these deaths indicated a danger for human health. Were the birds carrying a disease? A toxin?\u003c/p>\n\u003cp>Carcasses were shipped to the U.S. Geological Survey’s National Wildlife Health Center in Madison, Wisconsin. “They did all sorts of analyses for viral and bacterial diseases, toxins in the tissues,” Parrish said. “We’re trying to eliminate smoking guns. But all of those things—not found. No parasites, nothing we can hang our hat on. But there was lots of emaciation.”\u003c/p>\n\u003cp>Like many of his peers, Piatt was aware that these deaths were happening at the same time that the ocean was experiencing a record high heat wave, exacerbated by a ridge of high pressure on the West Coast that scientists were calling “the Blob.” But still, he wondered, “What could account for a decline in the food supply from California to the Bering Sea all at the same time?”\u003c/p>\n\u003cp>To get the answer, the scientists started ruling things out.\u003c/p>\n\u003cp>The first question: Could the fish that the murres eat have moved elsewhere in response to the warmer water? It’s well understood that fish respond in specific ways when the ocean temperature changes, sometimes moving north, south or deeper down. “But the thing is, murres can go anywhere in a matter of hours,” Piatt said.\u003c/p>\n\u003cp>The researchers also looked into whether overfishing could be the answer, but that didn’t hold water, either.\u003c/p>\n\u003cp>Next, they investigated whether the fish were surviving from egg to larvae. Some juvenile stock were failing, sure, but not enough to explain the large number of starving birds.\u003c/p>\n\u003cp>[ad floatright]\u003c/p>\n\u003cp>As Piatt kept looking into it, he said he got pushback from some in the field who wanted to know how, in the absence of a clear explanation, he could still believe it was a single event that caused the birds to starve to death. But Piatt said, “There has never been such a thing. You really think that it’s a coincidence that they’re dying down there and dying up here?

He started looking from the bottom up: What were the food sources that the fish were eating? He found that as the water had warmed, phytoplankton and zooplankton, the smallest ocean organisms that provide the base of the food web, had changed.\u003c/div>\n\u003cdiv class=\"media media-element-container media-image_centered_medium\">\n\u003cp>“The older, fatter, nutritionally richer zooplankton were replaced by southerly or offshore species that weren’t as big and nutritionally rich,” Piatt said. “This was observed in the Gulf of Alaska and off California and in various studies.”\u003c/p>\n\u003cp>At the same time, Piatt dove into studies that found that when water gets hotter, fish like cod, flounder, pollock and hake respond by increasing their metabolism. “If you turn up the temperature by a couple degrees, they have to double their food intake,” Piatt said. “It’s a huge deal.”\u003c/p>\n\u003cp>It turns out that those fish feed on the same prey as the murres.\u003c/p>\n\u003cp>And the murres have an Achilles heel: They have to eat more than half their body mass every day. Based on their normal diet in Alaska, that’s typically 60-120 fatty forage fish every day—double that, if only leaner prey is available. By comparison, cod of similar size to a murre would only need to eat about 0.4-1.5 percent of their body mass per day—just 1 to 3 fatty fish.\u003c/p>\n\u003cp>The double-whammy caused by warming waters—less nutritionally rich food sources and more competition for the food available—is what Piatt and his co-authors hypothesize led to the common murres deaths.\u003c/p>\n\u003cp>If murres can’t fully meet their food demand every day, their body condition begins to decline quickly. “If they can’t find \u003cem>any\u003c/em> food for 3-5 days, they will die of starvation,” the authors write in the new study.\u003c/p>\n\u003cp>\u003cstrong>What Caused the Marine Heat Wave\u003c/strong>\u003c/p>\n\u003cp>The extreme heat in the ocean from 2014-2016 was a result of several factors. Piatt describes it like a step ladder:\u003c/p>\n\u003cul>\n\u003cli>At the base is the ocean getting warmer due to global warming. Global warming contributed about 25 percent of the warming in the heat wave.\u003c/li>\n\u003cli>Next, the Pacific Decadal Oscillation, a recurring pattern of ocean-atmosphere climate variability that leads to periods of warming in the mid-latitude Pacific—that contributed about 35 percent of the heat.\u003c/li>\n\u003cli>As part of that, there was a strong El Niño from 2015-2016, which led to warming from California’s coast up to Alaska’s.\u003c/li>\n\u003c/ul>\n\u003cp>“If you remove all those signals you’ll see about a quarter of the heat is still unaccounted for, said Piatt. “That’s the Blob.” The Blob developed when a ridge of high pressure formed over the land on the northwestern coast of North America and blocked airflow from the Pacific to the interior, trapping heat over the ocean.\u003c/p>\n\u003cp>“It was the biggest marine heat wave so far on record,” said Thomas Frölicher, a climate scientist at the University of Bern in Switzerland who was not involved in the new study. “Usually, we are used to heat waves over land. They are much smaller in size, and they do not last as long. In the ocean, this heat wave lasted two or three years.”\u003c/p>\n\u003cp>In the past 35 years, marine heat waves have doubled in frequency, Frölicher said. And as global temperatures continue to rise, they will become even more commonplace.\u003c/p>\n\u003cp>“If we follow a high-greenhouse-gas-emissions scenario, these heat waves will become \u003ca href=\"https://www.nature.com/articles/s41586-018-0383-9\" target=\"_blank\" rel=\"noopener noreferrer\">50 times more frequent\u003c/a> than preindustrial times” by 2100, Frölicher said. A low-emissions scenario, consistent with the \u003ca href=\"https://insideclimatenews.org/tags/paris-climate-agreement\" target=\"_blank\" rel=\"noopener noreferrer\">Paris climate agreement\u003c/a>, would still see 20 times more heat waves, he said.\u003c/p>\n\u003cp>“What that means is that in some regions, they will become permanent heat waves,” he said. The mass deaths of common murres suggests what that may look like. “This gives us some insight into the future.”\u003c/p>\n\u003c/div>\n\n",

As that heat builds up, it’s having devastating consequences.\u003c/p>\n\u003cp>“When I heard the numbers of birds being killed in California and Oregon and Washington and many areas of Alaska, as that unfolded, it was biblical to me,” said John Piatt, a biologist with the U.S. Geological Survey who was the lead author of the new paper on the bird deaths and has been studying common murres for 40 years.\u003c/p>\n\u003cp>“This bird doesn’t fail unless there aren’t enough high density patches of food to serve their high demand needs.

Common murres are known for their ability to adapt. “Murres are the ultimate predator—they’re extremely well adapted, they can dive to 200 meters, and they live on the Continental Shelf,” he said. “Anywhere along there is their domain. And they’re the fastest flying sea bird.”\u003c/p>\n\u003cp>Yet murres were washing in with the tides—sometimes 10 birds at a time, sometimes 100.\u003c/p>\n\u003cp>After Irons’ discovery on New Year’s Day, everything changed, said Julia Parrish, a biologist at the University of Washington who leads the Coastal Observation and Seabird Survey Team and was a co-author of the study. Federal agencies started to get involved and were able to fly along the coastline and send more people to conduct surveys.\u003cimg loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-1955899 alignleft\" src=\"https://ww2.kqed.org/app/uploads/sites/35/2020/01/Common-Murre-Populations.png\" alt=\"\" width=\"529\" height=\"770\" srcset=\"https://cdn.kqed.org/wp-content/uploads/sites/35/2020/01/Common-Murre-Populations.png 529w, https://cdn.kqed.org/wp-content/uploads/sites/35/2020/01/Common-Murre-Populations-160x233.png 160w\" sizes=\"(max-width: 529px) 100vw, 529px\">\u003c/p>\n\u003cp>Surveys in the Gulf of Alaska conducted by the Interior Department turned up more than 20,000 dead murres, and the public reported 21,435 more to the department.\u003c/p>\n\u003cp>The scientists reached out to bird and rehabilitation centers from southern California to Alaska and found that, out of 66 that responded, 37 reported receiving injured or dead murres—a total of 3,365 birds. The body count ticked higher.\u003c/p>\n\u003cp>\u003cstrong>The Investigation\u003c/strong>\u003c/p>\n\u003cp>The first thing the scientists needed to know was whether these deaths indicated a danger for human health. Were the birds carrying a disease? A toxin?\u003c/p>\n\u003cp>Carcasses were shipped to the U.S. Geological Survey’s National Wildlife Health Center in Madison, Wisconsin. “They did all sorts of analyses for viral and bacterial diseases, toxins in the tissues,” Parrish said. “We’re trying to eliminate smoking guns. But all of those things—not found. No parasites, nothing we can hang our hat on. But there was lots of emaciation.”\u003c/p>\n\u003cp>Like many of his peers, Piatt was aware that these deaths were happening at the same time that the ocean was experiencing a record high heat wave, exacerbated by a ridge of high pressure on the West Coast that scientists were calling “the Blob.” But still, he wondered, “What could account for a decline in the food supply from California to the Bering Sea all at the same time?”\u003c/p>\n\u003cp>To get the answer, the scientists started ruling things out.\u003c/p>\n\u003cp>The first question: Could the fish that the murres eat have moved elsewhere in response to the warmer water? It’s well understood that fish respond in specific ways when the ocean temperature changes, sometimes moving north, south or deeper down. “But the thing is, murres can go anywhere in a matter of hours,” Piatt said.\u003c/p>\n\u003cp>The researchers also looked into whether overfishing could be the answer, but that didn’t hold water, either.\u003c/p>\n\u003cp>Next, they investigated whether the fish were surviving from egg to larvae. Some juvenile stock were failing, sure, but not enough to explain the large number of starving birds.\u003c/p>\n\u003cp>\u003c/p>\u003c/div>",

"content": "\u003cp>Some wolf puppies are unexpectedly willing to play fetch, according to scientists who saw young wolves retrieve a ball thrown by a stranger and bring it back at that person’s urging.\u003c/p>\n\u003cp>This behavior wouldn’t be surprising in a dog. But wolves are thought to be less responsive to human cues because they haven’t gone through thousands of years of domestication.\u003cspan style=\"font-weight: 400\"> [pullquote citation='Christina Hansen Wheat, Stockholm University']‘When I saw the first puppy fetch — I still get goosebumps when I talk about this — it was such a surprise.’[/pullquote]\u003c/span>\u003c/p>\n\u003cp>Exactly how dogs emerged from a now-extinct population of ancient wolves is a mystery. Wolves are large, dangerous carnivores, and yet they were the first animals that humans tamed. More than 15,000 years ago, when humans were still hunter-gatherers, this large predator somehow \u003ca href=\"https://www.npr.org/2013/11/14/244988049/old-dogs-new-data-canines-may-have-been-domesticated-in-europe\">began\u003c/a> cozying up to people, eventually becoming their “best friend.”\u003c/p>\n\u003cp>To try to get clues about how that happened, scientists such as \u003ca href=\"https://www.su.se/english/profiles/chha9511-1.192949\">Christina Hansen Wheat\u003c/a> of Stockholm University in Sweden have been studying the differences between dogs and modern wolves. As part of her work, she raised litters of wolf puppies, feeding them and acclimating them to her presence but not playing with them or training them.\u003c/p>\n\u003cp>At the age of 8 weeks, the wolf pups were put through a series of standard behavior tests that were administered by a person the wolves had never met.\u003c/p>\n\u003cp>[ad fullwidth]\u003c/p>\n\u003cp>This set of tests is normally used by dog breeders, says Hansen Wheat, to assess how their puppies act in social situations. “The fetching test just happened to be part of this test battery. It wasn’t something we were targeting at all,” she says.\u003c/p>\n\u003cp>The person conducting the test threw a tennis ball and urged the wolf puppy to bring it back. Two litters of puppies utterly failed to do this, surprising the scientists not at all.\u003c/p>\n\u003cp>“There’s some hypotheses out there that the ability to understand human social cues is a unique dog trait, a trait that arose after domestication had been initiated,” Hansen Wheat explains, so fetching on command is not a behavior expected in wolves.\u003c/p>\n\u003cp>But then a third litter went through the tests. And as she watched through a window, one of the wolf puppies went for the ball and returned it to the tester, according to a \u003ca href=\"https://www.cell.com/iscience/fulltext/S2589-0042(19)30557-7\">report\u003c/a> in the journal \u003cem>iScience\u003c/em>.\u003c/p>\n\u003cp>“When I saw the first puppy fetch — I still get goosebumps when I talk about this — it was such a surprise,” Hansen Wheat says. “It wasn’t just one puppy, it was actually three of them.

They used parrots that had previously been trained to understand that specific tokens, in the form of small metal rings, could be traded for a food treat through an exchange window.\u003c/p>\n\u003cp>[ad fullwidth]\u003c/p>\n\u003cp>In their experiment, this exchange window was covered up and closed on one bird’s cage, making it impossible for that bird to trade. The bird had a pile of tokens in its cage but no way to use them. Meanwhile, its neighbor in an adjacent cage had an open exchange window — but no tokens for food.\u003c/p>\n\u003cp>After sizing up the situation, the token-rich bird would help out its pal by passing tokens through an opening between the two bird enclosures. And the bird shared even though it didn’t partake in the walnut payoff.\u003c/p>\n\u003cp>“The African greys gave the token beak-to-beak with their partner,” Brucks says. “It was not just one token. Many of them transferred all 10 tokens, one after the other, always watching how their partner got the food for it, whereas they themselves did not get anything.”\u003c/p>\n\u003cp>Later, scientists reversed birds’ roles to see if the recipient of this generosity would pay back those favors. And the birds did.\u003c/p>\n\u003cp>“In the very first trial, they could not have known that the roles would be reversed afterward,” says Brucks, who notes that the parrots seemed to have an intrinsic desire to help out their partner. The eight birds tested all knew each other and lived in the same social group.\u003c/p>\n\u003cp>It seems that the birds weren’t just being playful with the tokens, but really understood when and why the token was needed. That’s because the birds would rarely pass a token over if the neighbor bird’s exchange window was closed up.\u003c/p>\n\u003cp>This study is a starting point to explore what exactly is going on in the birds’ minds, Brucks says.\u003c/p>\n\u003cp>A similar study in \u003ca href=\"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4484978/\">ravens\u003c/a> did not find this effect. And when Brucks tested blue-headed macaws, they weren’t helpful either. The macaws tried to bring the tokens as close as possible to the experimenter but did not transfer the token to the partner, Brucks says.\u003c/p>\n\u003cp>“We are really interested in this topic, and it’s an important topic. The problem is it’s very, very hard to design an experiment to truly demonstrate what is truly going on with these animals,” says \u003ca href=\"https://projects.iq.harvard.edu/animals/people/irene-m-pepperberg\">Irene Pepperberg\u003c/a>, a Harvard researcher whose work with a famous African grey parrot named Alex helped reveal the sophisticated cognitive abilities of these birds.\u003c/p>\n\u003cp>Pepperberg has also done \u003ca href=\"https://www.academia.edu/25811313/A_study_of_sharing_and_reciprocity_in_grey_parrots_Psittacus_erithacus_\">experiments\u003c/a> to test African greys’ willingness to help, using a different setup, and found that one parrot appeared to have some understanding of sharing — but it didn’t seem like the parrots were spontaneously super-altruistic.\u003c/p>\n\u003cp>Still, \u003ca href=\"https://news.uchicago.edu/profile/peggy-mason\">Peggy Mason\u003c/a> of the University of Chicago believes that this new study in parrots is striking.\u003c/p>\n\u003cp>\u003c/p>\n\u003cp>“When they gave the token, the other bird was getting the food and they were not,” Mason says. “I think they had the sense that this was a useful token, and that this token would turn into food for the other bird. It’s very shocking. It’s surprisingly giving, just because the only thing the bird doing it gets is that warm glow of helping.”\u003c/p>\n\u003cdiv class=\"fullattribution\">Copyright 2020 NPR.

The bird had a pile of tokens in its cage but no way to use them. Meanwhile, its neighbor in an adjacent cage had an open exchange window — but no tokens for food.\u003c/p>\n\u003cp>After sizing up the situation, the token-rich bird would help out its pal by passing tokens through an opening between the two bird enclosures. And the bird shared even though it didn’t partake in the walnut payoff.\u003c/p>\n\u003cp>“The African greys gave the token beak-to-beak with their partner,” Brucks says. “It was not just one token. Many of them transferred all 10 tokens, one after the other, always watching how their partner got the food for it, whereas they themselves did not get anything.”\u003c/p>\n\u003cp>Later, scientists reversed birds’ roles to see if the recipient of this generosity would pay back those favors. And the birds did.\u003c/p>\n\u003cp>“In the very first trial, they could not have known that the roles would be reversed afterward,” says Brucks, who notes that the parrots seemed to have an intrinsic desire to help out their partner. The eight birds tested all knew each other and lived in the same social group.\u003c/p>\n\u003cp>It seems that the birds weren’t just being playful with the tokens, but really understood when and why the token was needed. That’s because the birds would rarely pass a token over if the neighbor bird’s exchange window was closed up.\u003c/p>\n\u003cp>This study is a starting point to explore what exactly is going on in the birds’ minds, Brucks says.\u003c/p>\n\u003cp>A similar study in \u003ca href=\"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4484978/\">ravens\u003c/a> did not find this effect. And when Brucks tested blue-headed macaws, they weren’t helpful either. The macaws tried to bring the tokens as close as possible to the experimenter but did not transfer the token to the partner, Brucks says.\u003c/p>\n\u003cp>“We are really interested in this topic, and it’s an important topic. The problem is it’s very, very hard to design an experiment to truly demonstrate what is truly going on with these animals,” says \u003ca href=\"https://projects.iq.harvard.edu/animals/people/irene-m-pepperberg\">Irene Pepperberg\u003c/a>, a Harvard researcher whose work with a famous African grey parrot named Alex helped reveal the sophisticated cognitive abilities of these birds.\u003c/p>\n\u003cp>Pepperberg has also done \u003ca href=\"https://www.academia.edu/25811313/A_study_of_sharing_and_reciprocity_in_grey_parrots_Psittacus_erithacus_\">experiments\u003c/a> to test African greys’ willingness to help, using a different setup, and found that one parrot appeared to have some understanding of sharing — but it didn’t seem like the parrots were spontaneously super-altruistic.\u003c/p>\n\u003cp>Still, \u003ca href=\"https://news.uchicago.edu/profile/peggy-mason\">Peggy Mason\u003c/a> of the University of Chicago believes that this new study in parrots is striking.\u003c/p>\n\u003cp>\u003c/p>\n\u003cp>“When they gave the token, the other bird was getting the food and they were not,” Mason says. “I think they had the sense that this was a useful token, and that this token would turn into food for the other bird. It’s very shocking. It’s surprisingly giving, just because the only thing the bird doing it gets is that warm glow of helping.”\u003c/p>\n\u003cdiv class=\"fullattribution\">Copyright 2020 NPR.

The air is so clear you can see for miles, east to the distant peaks of the Sierra Nevada and west to the gentle slopes of the Coast Ranges. But Carson Jeffres and Jacob Katz are less interested in the view above them than the one at their feet. Standing knee-deep in a flooded field at Knaggs Ranch, a rice farm near Sacramento, they peer into a floating cage made of PVC pipe and mesh and prepare to check on its unusual inhabitants.\u003c/p>\n\u003cp>Jeffres opens the top of the cage and dips in a small net. When he pulls it out, a pair of plump fish, each the size of a pinky finger, wriggle inside. These are young Chinook salmon—a species imperiled in California. He holds up his catch for Katz to admire.\u003c/p>\n\u003cp>The two men are fish ecologists—Jeffres at the University of California, Davis, and Katz at the conservation-based non-profit California Trout—and they are testing a wild idea. To help save the Chinook, they are using rice fields as winter nurseries for young salmon migrating from their natal streams to the ocean.\u003c/p>\n\u003cp>Over the last century, water agencies have built levees along most of the state’s rivers to control floods and supply water to communities and farmers alike. But these levees also bar young Chinook from the floodplains that historically provided safe, food-rich places to grow on their journey to the Pacific. Today, more than half a million acres of these former floodplains in California’s immense interior valley are occupied by rice farms. Repurposing them as surrogate floodplains during the months they would otherwise lie fallow could be key to restoring endangered populations of wild-spawning Chinook.\u003c/p>\n\u003cp>[ad fullwidth]\u003c/p>\n\u003cp>“We can’t restore those floodplains,” says Rene Henery, California science director for the conservation non-profit Trout Unlimited, “but we can recover the functionality that the fish evolved with.”\u003c/p>\n\u003cp>California’s Central Valley is a flat expanse, flanked on either side by mountain ranges, that extends 400 miles down the middle of the state. Salmon once flourished in the streams and rivers that course through it. “One or two million came back every year,” says Peter Moyle, a fish ecologist at UC Davis. “They were up to 60 pounds and close to a meter long.”\u003c/p>\n\u003cp>For millennia, adult Chinook in California returned to spawn in the upper reaches of waterways that flow down from mountains surrounding the valley. Then, when the winter rainy season caused their natal streams to swell, the next generation of young fish would all swim downstream toward the sea, taking advantage of the many floodplains along the way.\u003c/p>\n\u003cp>The final stretch of their long journey would begin when the fish hit the Sacramento-San Joaquin River Delta, where the water slows, twisting and turning around the Delta’s many islands. Migrating young salmon have to navigate these braided waterways before making their way across the San Francisco Bay and through the Golden Gate Strait, the iconic narrow opening spanned by the Golden Gate Bridge that leads to the ocean.\u003c/p>\n\u003cfigure id=\"attachment_1951349\" class=\"wp-caption alignnone\" style=\"max-width: 640px\">\u003cimg loading=\"lazy\" decoding=\"async\" class=\"wp-image-1951349 size-complete_open_graph\" src=\"https://ww2.kqed.org/app/uploads/sites/35/2019/12/20190326_A_0785_full-1200x800.jpg\" alt=\"\" width=\"640\" height=\"427\">\u003cfigcaption class=\"wp-caption-text\">Jacob Katz examining the siphon after collecting a water sample to measure zooplankton in the floodplain near the Sacramento River. \u003ccite>(Jak Wonderly/bioGraphic)\u003c/cite>\u003c/figcaption>\u003c/figure>\n\u003cp>\u003cstrong>Habitat Loss\u003c/strong>\u003c/p>\n\u003cp>Today, few Central Valley salmon spawn in the wild. The region’s waterways have been completely remade into a system that includes 20 major dams and more than 1,600 miles of riverbank levees. While this engineered set-up tames flooding and supplies drinking and irrigation water, these benefits to people come at a cost to salmon. Dams block entry to the mountain streams where the fish once spawned, and levees block access to the valley-floor floodplains where young salmon once found plentiful food and shelter.\u003c/p>\n\u003cp>Across their range, Central Valley Chinook are all classified as a single species, but for management purposes the fish are divided into four runs according to the season when adults return from the Pacific Ocean to spawn. Two of those runs are listed under the federal Endangered Species Act, while the other two are considered federal populations of concern.\u003c/p>\n\u003cp>Engineered rivers are almost completely to blame. “Just as we’ve lost almost all the floodplain habitat, we’ve also lost pretty much all of the spawning habitat,” says Brian Ellrott, the Central Valley salmon recovery coordinator at the National Oceanic and Atmospheric Administration (NOAA), which leads the efforts to restore populations of these fish.\u003c/p>\n\u003cp>“They’re just straggling along right now,” Jeffres says. “They’re propped up by hatcheries.” State hatcheries release more than 32 million young salmon annually, and these fish dominate all four runs of Central Valley Chinook.\u003c/p>\n\u003cp>The best way to restore Chinook salmon, fish biologists say, is to give them back some of what they’ve lost. To provide more spawning grounds, NOAA plans to start transporting migrating adults past Central Valley dams―from the downstream side to the upstream reaches―as is done by wildlife agencies in the states of Washington and Oregon.\u003c/p>\n\u003cp>Restoration of degraded spawning grounds below dams will also be critical to their recovery. While most salmon return to their natal waters to spawn, a few stray in search of new homes. This penchant for exploration allows them to revisit waterways where they had previously been extinct for decades. Recent restoration efforts are starting to pay off: After an absence of 70 years, Chinook now return by the hundreds to spawn in Putah Creek, a tributary of the Sacramento River. Likewise, for the first time in more than half a century, a couple dozen Chinook have found their way back to historical spawning grounds in the San Joaquin River, which flows from the Sierra Nevada to the Delta.[pullquote align='right' citation='Jacob Katz, fish ecologist']‘Fish abundance equals water security. It doesn’t have to be fish versus farms―it can be fish and farms.’[/pullquote]\u003c/p>\n\u003cp>Restoring floodplain nurseries is a harder problem to solve, since this habitat has been more dramatically altered and requires changes on a much larger scale. Repurposing rice fields in the off-season may be a big part of the answer, and NOAA is supportive of the effort. “We’re pushing to make that happen,” Ellrott says. “Salmon are really resilient―I’m optimistic that if we give them the right nudge, we can restore them in the valley.”\u003c/p>\n\u003cp>Restorationists have good reason to think that prime nursery grounds are vital to the long-term survival of the region’s salmon. The most robust population of spring-run Chinook originates in Butte Creek, which runs along a wildlife refuge that contains some of the valley’s few remaining floodplains. The Butte Creek salmon population is wild-spawning and self-sustaining. “It’s the one successful population of spring-run salmon,” Jeffres says. Young salmon here are more likely to make it out to sea, and the adults more likely to return and spawn.\u003c/p>\n\u003cp>A probable reason for Butte Creek’s success is that it gives Chinook a place to grow and thrive. The creek’s young fish are larger than those elsewhere in the valley, and being bigger presumably boosts survival. “It makes the salmon more resilient,” Katz says, just like packing lunch before a long trip.\u003c/p>\n\u003cfigure id=\"attachment_1951231\" class=\"wp-caption aligncenter\" style=\"max-width: 540px\">\u003cimg loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-1951231\" src=\"https://ww2.kqed.org/app/uploads/sites/35/2019/12/RS40320__20190311_dji_0341_full-sfi.jpg\" alt=\"\" width=\"540\" height=\"360\" srcset=\"https://cdn.kqed.org/wp-content/uploads/sites/35/2019/12/RS40320__20190311_dji_0341_full-sfi.jpg 540w, https://cdn.kqed.org/wp-content/uploads/sites/35/2019/12/RS40320__20190311_dji_0341_full-sfi-160x107.jpg 160w\" sizes=\"(max-width: 540px) 100vw, 540px\">\u003cfigcaption class=\"wp-caption-text\">Restored wetlands from the air.

The first evidence came from scientists looking at the fate of young salmon in the Yolo Bypass. Built to contain a floodplain of the Sacramento River, the Bypass is an enormous flood control structure—about 40 miles long and two miles wide—that shunts water from the Sacramento River around the City of Sacramento. It’s bounded on either side by colossal, earthen levees that are more than 20 feet high and wide enough to drive on. When the river runs high, it overtops a weir at the north end of the levees. Water spills down inside the bypass, flooding it, then rejoins the river at the south end of the levees.\u003c/p>\n\u003c/div>\n\u003c/div>\n\u003c/div>\n\u003c/div>\n\u003c/div>\n\u003cdiv class=\"et_pb_section et_pb_section_14 text_section et_section_regular\">\n\u003cdiv class=\"et_pb_row et_pb_row_15 text_row et_pb_equal_columns\">\n\u003cdiv class=\"et_pb_column et_pb_column_1_2 et_pb_column_25 vertical-align-in-column text_column et_pb_css_mix_blend_mode_passthrough\">\n\u003cdiv class=\"et_pb_module et_pb_text et_pb_text_13 et_pb_text_align_left et_pb_bg_layout_light\">\n\u003cdiv class=\"et_pb_text_inner\">\n\u003cp>The Yolo Bypass only fills during the winter, and, when it does, some of the young salmon migrating downstream come along for the ride. During particularly wet winters, the bypass is so full it looks like an inland sea. “The floodplains are still there,” Katz says. “They’re just used differently, as bypasses.” A 1998 study concluded that salmon swept into the bypass grew faster than those that remained in the river.\u003c/p>\n\u003cp>Jeffres got similar results when he looked at fish in the Cosumnes, one of the state’s rare, free-flowing rivers that still has remnants of natural floodplains. In 2004, he found that young salmon in a floodplain grew faster than those in the Cosumnes River itself.\u003c/p>\n\u003cp>In 2009, the California Department of Water Resources decided to give salmon about 20,000 acres of floodplain habitat―one-third of the total acreage―in the Yolo Bypass. Most of the land there is privately owned and farmed for rice during the summer growing season. That decision caught the attention of rice farmer John Brennan, who wanted to keep fields in production in the Yolo Bypass.\u003c/p>\n\u003cp>Water is in short supply during the hot, dry Central Valley summers, especially during the state’s periodic severe droughts. Historically, the fight over this constrained resource has pitted growers against environmental laws that require allocating water for endangered fish like Chinook. Rather than playing this zero-sum game, Brennan has been looking for ways to integrate conservation with agriculture. “If you’re in the rice business, you’re in the water business―and if you’re in the water business, you’re in the fish business,” he says.\u003c/p>\n\u003cp>Katz puts it this way: “Fish abundance equals water security. It doesn’t have to be fish versus farms―it can be fish \u003cem>and\u003c/em> farms.”\u003c/p>\n\u003cdiv class=\"et_pb_section et_pb_section_18 text_section et_section_regular\">\n\u003cdiv class=\"et_pb_row et_pb_row_20 text_row et_pb_equal_columns\">\n\u003cdiv class=\"et_pb_column et_pb_column_1_2 et_pb_column_33 vertical-align-in-column text_column et_pb_css_mix_blend_mode_passthrough\">\n\u003cdiv class=\"et_pb_module et_pb_text et_pb_text_15 et_pb_text_align_left et_pb_bg_layout_light\">\n\u003cdiv class=\"et_pb_text_inner\">\n\u003cp>In 2010, Brennan joined forces with two environmentalists to see if rice fields in the bypass could be used as salmon nurseries during the winter, when the fields are dormant and fish are migrating downstream. After scouting the Yolo Bypass for available properties, Brennan and his partners settled on the rice fields of Knaggs Ranch as a chance to put their plan into practice. They bought the ranch and assembled a research team, starting with Jacob Katz since his father is one of Brennan’s partners. Katz invited Jeffres to join him, and the pair has collaborated ever since.\u003c/p>\n\u003cp>In the winter of 2012, the researchers flooded a five-acre corner of the ranch and released 10,000 young hatchery salmon in the fallow field. “When we first started, lots of farmers laughed and said it was the stupidest thing they’d ever heard,’” Jeffres says. He and Katz had their doubts, too. “It didn’t look like fish habitat,” Jeffres says, pointing across the ranch to their original test site. Flat brown fields stretch in all directions, and tidy mud berms divide the land into a patchwork of close-packed rice paddies. “We thought it might be the dumbest thing we’d ever done.”\u003c/p>\n\u003c/div>\n\u003c/div>\n\u003c/div>\n\u003c/div>\n\u003c/div>\n\u003cdiv class=\"et_pb_section et_pb_section_19 article_text_section et_section_regular\">\n\u003cdiv class=\"et_pb_row et_pb_row_21 text_row et_pb_equal_columns\">\n\u003cdiv class=\"et_pb_column et_pb_column_1_2 et_pb_column_35 text_column et_pb_css_mix_blend_mode_passthrough\">\n\u003cdiv class=\"et_pb_module et_pb_text et_pb_text_16 et_pb_text_align_left et_pb_bg_layout_light\">\n\u003cdiv class=\"et_pb_text_inner\">\n\u003cp>They worried they’d end up with a field full of dead fish. They weren’t concerned about residual pesticides, which are applied months earlier and break down relatively quickly in the environment, but they fretted about a host of other potential pitfalls. They thought the stagnant, shallow water in the field might get too warm for fish or make them easy prey for hungry birds. And they didn’t know whether the decomposition of rice stubble, which is left on the fields after the fall harvest, would deplete oxygen levels in the water.\u003c/p>\n\u003cp>At first the researchers couldn’t tell whether anything was happening. “Out in the fields in mid-winter it looks like a mud puddle. We couldn’t see the fish,” Katz says. “Then we ran a net through the water and caught fish with little potbellies. It was amazing.”\u003c/p>\n\u003cp>Their rice-field test subjects did far more than survive. They thrived, growing five-fold―from 1 gram to more than 5―in just six weeks. “They grew at the highest rates recorded in the Central Valley,” Jeffres says.\u003c/p>\n\u003cp>Ultimately, the scientists envision that the young salmon, instead of being introduced into rice fields by humans, will leave their natal waters and migrate downstream and into the bypass on their own. To make that journey possible even if the weir hasn’t overflowed, the California Department of Water Resources wants to add gates that can be opened to let salmon swim in and out of the rice fields on their way to the ocean.\u003c/p>\n\u003cp>While there are still some barriers left to remove, the possibility of wild-spawning, self-sustaining Chinook runs raised on rice farms is no longer just a pipe dream. In the years since they launched their pilot project, Jeffres and Katz have expanded their effort to encompass 20 acres and 50,000 fish, proving that it can work on a real-world scale. They have also found that, on average, salmon reared in these rice-field nurseries weigh 12 times more than those that grow up in the Sacramento River. The reason for this, Jeffres says, is that there’s so much more for them to eat.\u003c/p>\n\u003cfigure id=\"attachment_1951234\" class=\"wp-caption aligncenter\" style=\"max-width: 540px\">\u003cimg loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-1951234\" src=\"https://ww2.kqed.org/app/uploads/sites/35/2019/12/RS40324__20190419_A_1200_full-2-sfi.jpg\" alt=\"\" width=\"540\" height=\"360\" srcset=\"https://cdn.kqed.org/wp-content/uploads/sites/35/2019/12/RS40324__20190419_A_1200_full-2-sfi.jpg 540w, https://cdn.kqed.org/wp-content/uploads/sites/35/2019/12/RS40324__20190419_A_1200_full-2-sfi-160x107.jpg 160w\" sizes=\"(max-width: 540px) 100vw, 540px\">\u003cfigcaption class=\"wp-caption-text\">Hundreds of chinook salmon fry in a tank at the UC Davis Marine Laboratory. \u003ccite>(Jak Wonderly/bioGraphic)\u003c/cite>\u003c/figcaption>\u003c/figure>\n\u003cp>\u003cstrong>Back at Knaggs Ranch\u003c/strong>\u003c/p>\n\u003cp>Jeffres wants to know just how much more food the rice fields contain.

Holy moly!” Katz exclaims. “I am totally astonished.”\u003c/p>\n\u003cp>Jeffres is equally jazzed. “That’s insane!”\u003c/p>\n\u003cp>Inside the plastic bag, tiny freshwater crustaceans―or “bugs,” as the researchers call them―dart back and forth in constant motion. The water is so thick with them that it looks like a whirling cloud of pink.\u003c/p>\n\u003cp>These small crustaceans are the perfect food for young fish, and this haul is the best Katz and Jeffres have ever seen. Most of the bugs they netted belong to the genus \u003cem>Daphnia\u003c/em>, often dubbed water fleas for the way they swim in short hops. They’re here in such abundance because they thrive in shallow, algae-rich waters, from puddles to flooded fields to floodplains. “It’s magic when water slows down and spreads across a floodplain,” Katz says. “It’s liquid protein.”\u003c/p>\n\u003cp>Pickings are far slimmer in rivers. Katz holds up another bag, this one netted about an hour earlier from the Sacramento River. Just a few crustaceans scoot around inside it. “There’s basically nothing here,” he says. “By building levees, we’ve created rivers that are essentially food deserts.”\u003c/p>\n\u003cp>The Sacramento River has several flood control bypasses, and Katz estimates that, altogether, they contain up to 150,000 acres of rice fields that could be used as bug-rich salmon nurseries. Another 500,000 acres of rice farms lie along the Sacramento River but outside bypasses―and he thinks they may be able to help salmon, too.\u003c/p>\n\u003cp>One of these is River Garden Farms, which lies a short stretch upriver from Knaggs Ranch and is managed by Roger Cornwell. Like Brennan, Cornwell wondered if his fields could benefit salmon, despite the fact that the land is not in a bypass. “I met Jacob Katz and started talking to him about what we could do,” he says. Katz proposed another wild idea, one that could solve the food-desert problem: bug farming.\u003c/p>\n\u003cp>They wanted to know, Jeffres says, “If we can’t bring the fish to the floodplain, can we bring the floodplain to the fish?”\u003c/p>\n\u003cp>River Garden Farms is separated from the Sacramento River by a levee, atop which sits the Rough and Ready Pumping Plant, which was installed in 1915 to irrigate fields. The plant houses five glossy, black, massive pumps—each about six feet tall—which fill the pump house with a low roar. This past winter, the team took advantage of the setup and flooded a fallow rice field to raise bugs, then pumped the food-rich water into the Sacramento River to feed young fish as they swam through.\u003c/p>\n\u003cp>To test whether the bugs would reach their intended recipients, the researchers placed cages of young salmon at intervals along a mile or so of the river. The Rough and Ready pumps delivered bugs starting in late February, and Jacob Montgomery and Jennifer Kronk of California Trout took weekly measurements of the caged fish. By late March, when we visit, all the bugs have been pumped off the field. The field crew pulls on their waders and heads out to the river to see if the experiment worked.\u003c/p>\n\u003cp>They start at a site upstream of the pumping plant, where the caged fish didn’t get any field-raised bugs. Montgomery and Kronk wrestle a cage to the river’s muddy bank. Montgomery hefts the cage above the water, revealing young salmon that flash silver as they flip back and forth in distress. The team works fast so as to get the fish back to the river as soon as possible. Montgomery places each fish in a tray with a ruler, splashing it with water to keep it calm and still, and calls out the length for Kronk to record. Then he passes it to her for weighing. When the measuring is done, he estimates that the upstream fish averaged about 55 millimeters long and weighed around 2 grams.\u003c/p>\n\u003cp>Moving downstream to the next site, Kronk scoops up a fish collected right by the pump outfall. This site got the most bugs delivered from the rice field―if the experiment works, they’ll see it here.\u003c/p>\n\u003cp>“Oh, he’s fat,” Kronk says.\u003c/p>\n\u003cp>She lays it in the measuring tray. It’s 65 millimeters and 2.5 grams, considerably bigger than the upstream average. The next fish is even fatter, at 66 mm and just over 3 g, and the one after that is fatter still, at 71 mm and 4 g.\u003c/p>\n\u003cp>“Wow, look at these guys. They’re doing great,” Montgomery says.\u003c/p>\n\u003cp>Although supplying bugs to fish in a free-flowing river doesn’t guarantee delivery, a system that monitors migrating salmon is already in place―so the researchers will know when to expect the fish and can serve them food from the fields at just the right time. “We can pump bugs into the river when fish are passing by,” Katz says. By spring, the salmon will have completed their journey, and the rice fields will be drained and ready for planting.\u003c/p>\n\u003cfigure id=\"attachment_1951235\" class=\"wp-caption aligncenter\" style=\"max-width: 540px\">\u003cimg loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-1951235\" src=\"https://ww2.kqed.org/app/uploads/sites/35/2019/12/RS40325__20190424_2341_full-sfi.jpg\" alt=\"\" width=\"540\" height=\"360\" srcset=\"https://cdn.kqed.org/wp-content/uploads/sites/35/2019/12/RS40325__20190424_2341_full-sfi.jpg 540w, https://cdn.kqed.org/wp-content/uploads/sites/35/2019/12/RS40325__20190424_2341_full-sfi-160x107.jpg 160w\" sizes=\"(max-width: 540px) 100vw, 540px\">\u003cfigcaption class=\"wp-caption-text\">Rachelle Tallman, UC Davis Graduate student, creating an incision in a salmon fry after inserting a tracking tag. \u003ccite>(Jak Wonderly/bioGraphic)\u003c/cite>\u003c/figcaption>\u003c/figure>\n\u003cp>Fish biologists have long assumed that the larger young salmon are when they navigate the Delta, the faster they can swim and the better their chances of survival. “It’s a really dangerous place,” Trout Unlimited’s Rene Henery says. “There are lots of introduced predatory fish.” To date, however, there is no direct evidence that size is important to survival.\u003c/p>\n\u003cp>“In the fish world, we say bigger fish are more likely to make it to the ocean. But no one has actually looked at survival,” says Rachelle Tallman, a graduate student in fish ecology at UC Davis. Tallman is now heading up a project to do just that.\u003c/p>\n\u003cp>The project is part of an effort by the California Rice Commission to incentivize farmers to manage their rice fields in a way that benefits local wildlife. Paul Buttner, who manages environmental affairs for the commission, currently pays farmers to flood their fields for water birds migrating along the Pacific Flyway. He hopes to launch a similar program for salmon that would compensate farmers for creating floodplain nurseries for young, migrating fish. But first he needs solid proof that it works.\u003c/p>\n\u003cp>“How many salmon from fields survive and go out the Golden Gate?” Buttner asks. “More than those that grow up in the river?”\u003c/p>\n\u003cp>While the Rough and Ready plant was pumping bugs into the Sacramento River, Tallman was setting up a different experiment to assess how size affects a salmon’s success. She reared two sets of young salmon: some in a laboratory tank and others in rice fields in the Yolo Bypass. Now, on a warm April day near the edge of the bypass, she’s pulling fish from the rice fields and equipping them with acoustic tags so she can compare survival rates as they swim out to, and beyond, the Golden Gate.\u003c/p>\n\u003cp>Tallman stands at a fish-surgery station sheltered by a white tent. As she slips a young salmon into a bucket of anesthetic, she alerts her team that a surgery is in progress. “Dope!” she calls out. A minute later the fish has stopped wriggling and Tallman springs into action. In rapid succession, she weighs it, measures it, and places it on a foam block. Cool water streams across the fish, which lies motionless apart from flapping gills.\u003c/p>\n\u003cp>Surgical scissors in hand, Tallman cuts a small opening in its belly and pushes a centimeter-long tag inside. She closes the wound with a single stitch and knots both ends. “Fish out of surgery,” she calls. A crew member collects the salmon and puts it in a recovery bucket. The whole operation, including anesthesia, takes just two minutes. Then Tallman picks up another fish and starts the process anew. “Dope!” she says.\u003c/p>\n\u003cp>Back at the lab, another crew tags tank-reared fish. Collectively, the team tags more than 750 salmon.\u003c/p>\n\u003cp>A day after the surgeries, Tallman releases her tagged salmon into the wild, sending some into the Sacramento River and some into the Yolo Bypass, which drains into the Sacramento. About 200 underwater acoustic receivers will track their progress.\u003c/p>\n\u003cp>By early May, the first tagged fish have navigated the perils of the Delta. Now, they must traverse the San Francisco Bay—a huge body of water that covers more than 500 square miles. But this part of their journey is less risky. Once they’ve gotten this far, most young salmon readily find their way across the Bay and swim through its narrow opening beneath the Golden Gate Bridge, out into the Pacific Ocean. It will likely be December before Tallman can crunch all the data and tell Buttner whether—and how much—the rice field nurseries boost survival rates for the salmon. While the final verdict is still out, Buttner says they’re all hoping for a nice Christmas present.\u003c/p>\n\u003cp>The fish in Tallman’s study that do make it to the Pacific and survive in the open ocean will eventually attempt to return as adults to spawn in the Central Valley’s extensive but highly altered river system. It’s a journey the scientists hope will become at least slightly less challenging in the years to come. “We’re not going to get back what we once had,” Jeffres says. “But we can mimic it.” He and Katz envision waterways that are managed for flood control and farming but also for Chinook survival, ones with rice-field nurseries and bug farms to help restore self-sustaining salmon populations.\u003c/p>\n\u003cp>“It’s about welcoming the wild back into human landscapes in a way that makes sense,” Katz says. “We’re reimagining the system to work with nature.”\u003c/p>\n\u003c/div>\n\u003c/div>\n\u003c/div>\n\u003c/div>\n\u003c/div>\n\u003c/div>\n\u003c/div>\n\u003c/div>\n\u003c/div>\n\u003c/div>\n\n",

The air is so clear you can see for miles, east to the distant peaks of the Sierra Nevada and west to the gentle slopes of the Coast Ranges. But Carson Jeffres and Jacob Katz are less interested in the view above them than the one at their feet. Standing knee-deep in a flooded field at Knaggs Ranch, a rice farm near Sacramento, they peer into a floating cage made of PVC pipe and mesh and prepare to check on its unusual inhabitants.\u003c/p>\n\u003cp>Jeffres opens the top of the cage and dips in a small net. When he pulls it out, a pair of plump fish, each the size of a pinky finger, wriggle inside. These are young Chinook salmon—a species imperiled in California. He holds up his catch for Katz to admire.\u003c/p>\n\u003cp>The two men are fish ecologists—Jeffres at the University of California, Davis, and Katz at the conservation-based non-profit California Trout—and they are testing a wild idea. To help save the Chinook, they are using rice fields as winter nurseries for young salmon migrating from their natal streams to the ocean.\u003c/p>\n\u003cp>Over the last century, water agencies have built levees along most of the state’s rivers to control floods and supply water to communities and farmers alike. But these levees also bar young Chinook from the floodplains that historically provided safe, food-rich places to grow on their journey to the Pacific. Today, more than half a million acres of these former floodplains in California’s immense interior valley are occupied by rice farms. Repurposing them as surrogate floodplains during the months they would otherwise lie fallow could be key to restoring endangered populations of wild-spawning Chinook.\u003c/p>\n\u003cp>\u003c/p>\u003c/div>",

Salmon once flourished in the streams and rivers that course through it. “One or two million came back every year,” says Peter Moyle, a fish ecologist at UC Davis. “They were up to 60 pounds and close to a meter long.”\u003c/p>\n\u003cp>For millennia, adult Chinook in California returned to spawn in the upper reaches of waterways that flow down from mountains surrounding the valley. Then, when the winter rainy season caused their natal streams to swell, the next generation of young fish would all swim downstream toward the sea, taking advantage of the many floodplains along the way.\u003c/p>\n\u003cp>The final stretch of their long journey would begin when the fish hit the Sacramento-San Joaquin River Delta, where the water slows, twisting and turning around the Delta’s many islands. Migrating young salmon have to navigate these braided waterways before making their way across the San Francisco Bay and through the Golden Gate Strait, the iconic narrow opening spanned by the Golden Gate Bridge that leads to the ocean.\u003c/p>\n\u003cfigure id=\"attachment_1951349\" class=\"wp-caption alignnone\" style=\"max-width: 640px\">\u003cimg loading=\"lazy\" decoding=\"async\" class=\"wp-image-1951349 size-complete_open_graph\" src=\"https://ww2.kqed.org/app/uploads/sites/35/2019/12/20190326_A_0785_full-1200x800.jpg\" alt=\"\" width=\"640\" height=\"427\">\u003cfigcaption class=\"wp-caption-text\">Jacob Katz examining the siphon after collecting a water sample to measure zooplankton in the floodplain near the Sacramento River. \u003ccite>(Jak Wonderly/bioGraphic)\u003c/cite>\u003c/figcaption>\u003c/figure>\n\u003cp>\u003cstrong>Habitat Loss\u003c/strong>\u003c/p>\n\u003cp>Today, few Central Valley salmon spawn in the wild. The region’s waterways have been completely remade into a system that includes 20 major dams and more than 1,600 miles of riverbank levees. While this engineered set-up tames flooding and supplies drinking and irrigation water, these benefits to people come at a cost to salmon. Dams block entry to the mountain streams where the fish once spawned, and levees block access to the valley-floor floodplains where young salmon once found plentiful food and shelter.\u003c/p>\n\u003cp>Across their range, Central Valley Chinook are all classified as a single species, but for management purposes the fish are divided into four runs according to the season when adults return from the Pacific Ocean to spawn. Two of those runs are listed under the federal Endangered Species Act, while the other two are considered federal populations of concern.\u003c/p>\n\u003cp>Engineered rivers are almost completely to blame. “Just as we’ve lost almost all the floodplain habitat, we’ve also lost pretty much all of the spawning habitat,” says Brian Ellrott, the Central Valley salmon recovery coordinator at the National Oceanic and Atmospheric Administration (NOAA), which leads the efforts to restore populations of these fish.\u003c/p>\n\u003cp>“They’re just straggling along right now,” Jeffres says. “They’re propped up by hatcheries.” State hatcheries release more than 32 million young salmon annually, and these fish dominate all four runs of Central Valley Chinook.\u003c/p>\n\u003cp>The best way to restore Chinook salmon, fish biologists say, is to give them back some of what they’ve lost. To provide more spawning grounds, NOAA plans to start transporting migrating adults past Central Valley dams―from the downstream side to the upstream reaches―as is done by wildlife agencies in the states of Washington and Oregon.\u003c/p>\n\u003cp>Restoration of degraded spawning grounds below dams will also be critical to their recovery. While most salmon return to their natal waters to spawn, a few stray in search of new homes. This penchant for exploration allows them to revisit waterways where they had previously been extinct for decades. Recent restoration efforts are starting to pay off: After an absence of 70 years, Chinook now return by the hundreds to spawn in Putah Creek, a tributary of the Sacramento River. Likewise, for the first time in more than half a century, a couple dozen Chinook have found their way back to historical spawning grounds in the San Joaquin River, which flows from the Sierra Nevada to the Delta.\u003c/p>\u003c/div>",

Repurposing rice fields in the off-season may be a big part of the answer, and NOAA is supportive of the effort. “We’re pushing to make that happen,” Ellrott says. “Salmon are really resilient―I’m optimistic that if we give them the right nudge, we can restore them in the valley.”\u003c/p>\n\u003cp>Restorationists have good reason to think that prime nursery grounds are vital to the long-term survival of the region’s salmon. The most robust population of spring-run Chinook originates in Butte Creek, which runs along a wildlife refuge that contains some of the valley’s few remaining floodplains. The Butte Creek salmon population is wild-spawning and self-sustaining. “It’s the one successful population of spring-run salmon,” Jeffres says. Young salmon here are more likely to make it out to sea, and the adults more likely to return and spawn.\u003c/p>\n\u003cp>A probable reason for Butte Creek’s success is that it gives Chinook a place to grow and thrive. The creek’s young fish are larger than those elsewhere in the valley, and being bigger presumably boosts survival. “It makes the salmon more resilient,” Katz says, just like packing lunch before a long trip.\u003c/p>\n\u003cfigure id=\"attachment_1951231\" class=\"wp-caption aligncenter\" style=\"max-width: 540px\">\u003cimg loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-1951231\" src=\"https://ww2.kqed.org/app/uploads/sites/35/2019/12/RS40320__20190311_dji_0341_full-sfi.jpg\" alt=\"\" width=\"540\" height=\"360\" srcset=\"https://cdn.kqed.org/wp-content/uploads/sites/35/2019/12/RS40320__20190311_dji_0341_full-sfi.jpg 540w, https://cdn.kqed.org/wp-content/uploads/sites/35/2019/12/RS40320__20190311_dji_0341_full-sfi-160x107.jpg 160w\" sizes=\"(max-width: 540px) 100vw, 540px\">\u003cfigcaption class=\"wp-caption-text\">Restored wetlands from the air.

The first evidence came from scientists looking at the fate of young salmon in the Yolo Bypass. Built to contain a floodplain of the Sacramento River, the Bypass is an enormous flood control structure—about 40 miles long and two miles wide—that shunts water from the Sacramento River around the City of Sacramento. It’s bounded on either side by colossal, earthen levees that are more than 20 feet high and wide enough to drive on. When the river runs high, it overtops a weir at the north end of the levees. Water spills down inside the bypass, flooding it, then rejoins the river at the south end of the levees.\u003c/p>\n\u003c/div>\n\u003c/div>\n\u003c/div>\n\u003c/div>\n\u003c/div>\n\u003cdiv class=\"et_pb_section et_pb_section_14 text_section et_section_regular\">\n\u003cdiv class=\"et_pb_row et_pb_row_15 text_row et_pb_equal_columns\">\n\u003cdiv class=\"et_pb_column et_pb_column_1_2 et_pb_column_25 vertical-align-in-column text_column et_pb_css_mix_blend_mode_passthrough\">\n\u003cdiv class=\"et_pb_module et_pb_text et_pb_text_13 et_pb_text_align_left et_pb_bg_layout_light\">\n\u003cdiv class=\"et_pb_text_inner\">\n\u003cp>The Yolo Bypass only fills during the winter, and, when it does, some of the young salmon migrating downstream come along for the ride. During particularly wet winters, the bypass is so full it looks like an inland sea. “The floodplains are still there,” Katz says. “They’re just used differently, as bypasses.” A 1998 study concluded that salmon swept into the bypass grew faster than those that remained in the river.\u003c/p>\n\u003cp>Jeffres got similar results when he looked at fish in the Cosumnes, one of the state’s rare, free-flowing rivers that still has remnants of natural floodplains. In 2004, he found that young salmon in a floodplain grew faster than those in the Cosumnes River itself.\u003c/p>\n\u003cp>In 2009, the California Department of Water Resources decided to give salmon about 20,000 acres of floodplain habitat―one-third of the total acreage―in the Yolo Bypass. Most of the land there is privately owned and farmed for rice during the summer growing season. That decision caught the attention of rice farmer John Brennan, who wanted to keep fields in production in the Yolo Bypass.\u003c/p>\n\u003cp>Water is in short supply during the hot, dry Central Valley summers, especially during the state’s periodic severe droughts. Historically, the fight over this constrained resource has pitted growers against environmental laws that require allocating water for endangered fish like Chinook. Rather than playing this zero-sum game, Brennan has been looking for ways to integrate conservation with agriculture. “If you’re in the rice business, you’re in the water business―and if you’re in the water business, you’re in the fish business,” he says.\u003c/p>\n\u003cp>Katz puts it this way: “Fish abundance equals water security. It doesn’t have to be fish versus farms―it can be fish \u003cem>and\u003c/em> farms.”\u003c/p>\n\u003cdiv class=\"et_pb_section et_pb_section_18 text_section et_section_regular\">\n\u003cdiv class=\"et_pb_row et_pb_row_20 text_row et_pb_equal_columns\">\n\u003cdiv class=\"et_pb_column et_pb_column_1_2 et_pb_column_33 vertical-align-in-column text_column et_pb_css_mix_blend_mode_passthrough\">\n\u003cdiv class=\"et_pb_module et_pb_text et_pb_text_15 et_pb_text_align_left et_pb_bg_layout_light\">\n\u003cdiv class=\"et_pb_text_inner\">\n\u003cp>In 2010, Brennan joined forces with two environmentalists to see if rice fields in the bypass could be used as salmon nurseries during the winter, when the fields are dormant and fish are migrating downstream. After scouting the Yolo Bypass for available properties, Brennan and his partners settled on the rice fields of Knaggs Ranch as a chance to put their plan into practice. They bought the ranch and assembled a research team, starting with Jacob Katz since his father is one of Brennan’s partners. Katz invited Jeffres to join him, and the pair has collaborated ever since.\u003c/p>\n\u003cp>In the winter of 2012, the researchers flooded a five-acre corner of the ranch and released 10,000 young hatchery salmon in the fallow field. “When we first started, lots of farmers laughed and said it was the stupidest thing they’d ever heard,’” Jeffres says. He and Katz had their doubts, too. “It didn’t look like fish habitat,” Jeffres says, pointing across the ranch to their original test site. Flat brown fields stretch in all directions, and tidy mud berms divide the land into a patchwork of close-packed rice paddies. “We thought it might be the dumbest thing we’d ever done.”\u003c/p>\n\u003c/div>\n\u003c/div>\n\u003c/div>\n\u003c/div>\n\u003c/div>\n\u003cdiv class=\"et_pb_section et_pb_section_19 article_text_section et_section_regular\">\n\u003cdiv class=\"et_pb_row et_pb_row_21 text_row et_pb_equal_columns\">\n\u003cdiv class=\"et_pb_column et_pb_column_1_2 et_pb_column_35 text_column et_pb_css_mix_blend_mode_passthrough\">\n\u003cdiv class=\"et_pb_module et_pb_text et_pb_text_16 et_pb_text_align_left et_pb_bg_layout_light\">\n\u003cdiv class=\"et_pb_text_inner\">\n\u003cp>They worried they’d end up with a field full of dead fish. They weren’t concerned about residual pesticides, which are applied months earlier and break down relatively quickly in the environment, but they fretted about a host of other potential pitfalls. They thought the stagnant, shallow water in the field might get too warm for fish or make them easy prey for hungry birds. And they didn’t know whether the decomposition of rice stubble, which is left on the fields after the fall harvest, would deplete oxygen levels in the water.\u003c/p>\n\u003cp>At first the researchers couldn’t tell whether anything was happening. “Out in the fields in mid-winter it looks like a mud puddle. We couldn’t see the fish,” Katz says. “Then we ran a net through the water and caught fish with little potbellies. It was amazing.”\u003c/p>\n\u003cp>Their rice-field test subjects did far more than survive. They thrived, growing five-fold―from 1 gram to more than 5―in just six weeks. “They grew at the highest rates recorded in the Central Valley,” Jeffres says.\u003c/p>\n\u003cp>Ultimately, the scientists envision that the young salmon, instead of being introduced into rice fields by humans, will leave their natal waters and migrate downstream and into the bypass on their own. To make that journey possible even if the weir hasn’t overflowed, the California Department of Water Resources wants to add gates that can be opened to let salmon swim in and out of the rice fields on their way to the ocean.\u003c/p>\n\u003cp>While there are still some barriers left to remove, the possibility of wild-spawning, self-sustaining Chinook runs raised on rice farms is no longer just a pipe dream. In the years since they launched their pilot project, Jeffres and Katz have expanded their effort to encompass 20 acres and 50,000 fish, proving that it can work on a real-world scale. They have also found that, on average, salmon reared in these rice-field nurseries weigh 12 times more than those that grow up in the Sacramento River. The reason for this, Jeffres says, is that there’s so much more for them to eat.\u003c/p>\n\u003cfigure id=\"attachment_1951234\" class=\"wp-caption aligncenter\" style=\"max-width: 540px\">\u003cimg loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-1951234\" src=\"https://ww2.kqed.org/app/uploads/sites/35/2019/12/RS40324__20190419_A_1200_full-2-sfi.jpg\" alt=\"\" width=\"540\" height=\"360\" srcset=\"https://cdn.kqed.org/wp-content/uploads/sites/35/2019/12/RS40324__20190419_A_1200_full-2-sfi.jpg 540w, https://cdn.kqed.org/wp-content/uploads/sites/35/2019/12/RS40324__20190419_A_1200_full-2-sfi-160x107.jpg 160w\" sizes=\"(max-width: 540px) 100vw, 540px\">\u003cfigcaption class=\"wp-caption-text\">Hundreds of chinook salmon fry in a tank at the UC Davis Marine Laboratory. \u003ccite>(Jak Wonderly/bioGraphic)\u003c/cite>\u003c/figcaption>\u003c/figure>\n\u003cp>\u003cstrong>Back at Knaggs Ranch\u003c/strong>\u003c/p>\n\u003cp>Jeffres wants to know just how much more food the rice fields contain. He casts a long, white net across the shallow water of a rice field then draws it back carefully, keeping clear of the mud. Katz tips the contents into a plastic bag and lifts it high so they can both see.\u003c/p>\n\u003cp>“Holy shit! Holy shit! Holy moly!” Katz exclaims. “I am totally astonished.”\u003c/p>\n\u003cp>Jeffres is equally jazzed. “That’s insane!”\u003c/p>\n\u003cp>Inside the plastic bag, tiny freshwater crustaceans―or “bugs,” as the researchers call them―dart back and forth in constant motion. The water is so thick with them that it looks like a whirling cloud of pink.\u003c/p>\n\u003cp>These small crustaceans are the perfect food for young fish, and this haul is the best Katz and Jeffres have ever seen. Most of the bugs they netted belong to the genus \u003cem>Daphnia\u003c/em>, often dubbed water fleas for the way they swim in short hops. They’re here in such abundance because they thrive in shallow, algae-rich waters, from puddles to flooded fields to floodplains. “It’s magic when water slows down and spreads across a floodplain,” Katz says. “It’s liquid protein.”\u003c/p>\n\u003cp>Pickings are far slimmer in rivers. Katz holds up another bag, this one netted about an hour earlier from the Sacramento River. Just a few crustaceans scoot around inside it. “There’s basically nothing here,” he says. “By building levees, we’ve created rivers that are essentially food deserts.”\u003c/p>\n\u003cp>The Sacramento River has several flood control bypasses, and Katz estimates that, altogether, they contain up to 150,000 acres of rice fields that could be used as bug-rich salmon nurseries. Another 500,000 acres of rice farms lie along the Sacramento River but outside bypasses―and he thinks they may be able to help salmon, too.\u003c/p>\n\u003cp>One of these is River Garden Farms, which lies a short stretch upriver from Knaggs Ranch and is managed by Roger Cornwell. Like Brennan, Cornwell wondered if his fields could benefit salmon, despite the fact that the land is not in a bypass. “I met Jacob Katz and started talking to him about what we could do,” he says. Katz proposed another wild idea, one that could solve the food-desert problem: bug farming.\u003c/p>\n\u003cp>They wanted to know, Jeffres says, “If we can’t bring the fish to the floodplain, can we bring the floodplain to the fish?”\u003c/p>\n\u003cp>River Garden Farms is separated from the Sacramento River by a levee, atop which sits the Rough and Ready Pumping Plant, which was installed in 1915 to irrigate fields. The plant houses five glossy, black, massive pumps—each about six feet tall—which fill the pump house with a low roar. This past winter, the team took advantage of the setup and flooded a fallow rice field to raise bugs, then pumped the food-rich water into the Sacramento River to feed young fish as they swam through.\u003c/p>\n\u003cp>To test whether the bugs would reach their intended recipients, the researchers placed cages of young salmon at intervals along a mile or so of the river. The Rough and Ready pumps delivered bugs starting in late February, and Jacob Montgomery and Jennifer Kronk of California Trout took weekly measurements of the caged fish. By late March, when we visit, all the bugs have been pumped off the field. The field crew pulls on their waders and heads out to the river to see if the experiment worked.\u003c/p>\n\u003cp>They start at a site upstream of the pumping plant, where the caged fish didn’t get any field-raised bugs. Montgomery and Kronk wrestle a cage to the river’s muddy bank. Montgomery hefts the cage above the water, revealing young salmon that flash silver as they flip back and forth in distress. The team works fast so as to get the fish back to the river as soon as possible. Montgomery places each fish in a tray with a ruler, splashing it with water to keep it calm and still, and calls out the length for Kronk to record. Then he passes it to her for weighing. When the measuring is done, he estimates that the upstream fish averaged about 55 millimeters long and weighed around 2 grams.\u003c/p>\n\u003cp>Moving downstream to the next site, Kronk scoops up a fish collected right by the pump outfall. This site got the most bugs delivered from the rice field―if the experiment works, they’ll see it here.\u003c/p>\n\u003cp>“Oh, he’s fat,” Kronk says.\u003c/p>\n\u003cp>She lays it in the measuring tray. It’s 65 millimeters and 2.5 grams, considerably bigger than the upstream average. The next fish is even fatter, at 66 mm and just over 3 g, and the one after that is fatter still, at 71 mm and 4 g.\u003c/p>\n\u003cp>“Wow, look at these guys. They’re doing great,” Montgomery says.\u003c/p>\n\u003cp>Although supplying bugs to fish in a free-flowing river doesn’t guarantee delivery, a system that monitors migrating salmon is already in place―so the researchers will know when to expect the fish and can serve them food from the fields at just the right time. “We can pump bugs into the river when fish are passing by,” Katz says. By spring, the salmon will have completed their journey, and the rice fields will be drained and ready for planting.\u003c/p>\n\u003cfigure id=\"attachment_1951235\" class=\"wp-caption aligncenter\" style=\"max-width: 540px\">\u003cimg loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-1951235\" src=\"https://ww2.kqed.org/app/uploads/sites/35/2019/12/RS40325__20190424_2341_full-sfi.jpg\" alt=\"\" width=\"540\" height=\"360\" srcset=\"https://cdn.kqed.org/wp-content/uploads/sites/35/2019/12/RS40325__20190424_2341_full-sfi.jpg 540w, https://cdn.kqed.org/wp-content/uploads/sites/35/2019/12/RS40325__20190424_2341_full-sfi-160x107.jpg 160w\" sizes=\"(max-width: 540px) 100vw, 540px\">\u003cfigcaption class=\"wp-caption-text\">Rachelle Tallman, UC Davis Graduate student, creating an incision in a salmon fry after inserting a tracking tag. \u003ccite>(Jak Wonderly/bioGraphic)\u003c/cite>\u003c/figcaption>\u003c/figure>\n\u003cp>Fish biologists have long assumed that the larger young salmon are when they navigate the Delta, the faster they can swim and the better their chances of survival. “It’s a really dangerous place,” Trout Unlimited’s Rene Henery says. “There are lots of introduced predatory fish.” To date, however, there is no direct evidence that size is important to survival.\u003c/p>\n\u003cp>“In the fish world, we say bigger fish are more likely to make it to the ocean. But no one has actually looked at survival,” says Rachelle Tallman, a graduate student in fish ecology at UC Davis. Tallman is now heading up a project to do just that.\u003c/p>\n\u003cp>The project is part of an effort by the California Rice Commission to incentivize farmers to manage their rice fields in a way that benefits local wildlife. Paul Buttner, who manages environmental affairs for the commission, currently pays farmers to flood their fields for water birds migrating along the Pacific Flyway. He hopes to launch a similar program for salmon that would compensate farmers for creating floodplain nurseries for young, migrating fish. But first he needs solid proof that it works.\u003c/p>\n\u003cp>“How many salmon from fields survive and go out the Golden Gate?” Buttner asks. “More than those that grow up in the river?”\u003c/p>\n\u003cp>While the Rough and Ready plant was pumping bugs into the Sacramento River, Tallman was setting up a different experiment to assess how size affects a salmon’s success. She reared two sets of young salmon: some in a laboratory tank and others in rice fields in the Yolo Bypass. Now, on a warm April day near the edge of the bypass, she’s pulling fish from the rice fields and equipping them with acoustic tags so she can compare survival rates as they swim out to, and beyond, the Golden Gate.\u003c/p>\n\u003cp>Tallman stands at a fish-surgery station sheltered by a white tent. As she slips a young salmon into a bucket of anesthetic, she alerts her team that a surgery is in progress. “Dope!” she calls out. A minute later the fish has stopped wriggling and Tallman springs into action. In rapid succession, she weighs it, measures it, and places it on a foam block. Cool water streams across the fish, which lies motionless apart from flapping gills.\u003c/p>\n\u003cp>Surgical scissors in hand, Tallman cuts a small opening in its belly and pushes a centimeter-long tag inside. She closes the wound with a single stitch and knots both ends. “Fish out of surgery,” she calls. A crew member collects the salmon and puts it in a recovery bucket. The whole operation, including anesthesia, takes just two minutes. Then Tallman picks up another fish and starts the process anew. “Dope!” she says.\u003c/p>\n\u003cp>Back at the lab, another crew tags tank-reared fish. Collectively, the team tags more than 750 salmon.\u003c/p>\n\u003cp>A day after the surgeries, Tallman releases her tagged salmon into the wild, sending some into the Sacramento River and some into the Yolo Bypass, which drains into the Sacramento. About 200 underwater acoustic receivers will track their progress.\u003c/p>\n\u003cp>By early May, the first tagged fish have navigated the perils of the Delta. Now, they must traverse the San Francisco Bay—a huge body of water that covers more than 500 square miles. But this part of their journey is less risky. Once they’ve gotten this far, most young salmon readily find their way across the Bay and swim through its narrow opening beneath the Golden Gate Bridge, out into the Pacific Ocean. It will likely be December before Tallman can crunch all the data and tell Buttner whether—and how much—the rice field nurseries boost survival rates for the salmon. While the final verdict is still out, Buttner says they’re all hoping for a nice Christmas present.\u003c/p>\n\u003cp>The fish in Tallman’s study that do make it to the Pacific and survive in the open ocean will eventually attempt to return as adults to spawn in the Central Valley’s extensive but highly altered river system. It’s a journey the scientists hope will become at least slightly less challenging in the years to come. “We’re not going to get back what we once had,” Jeffres says. “But we can mimic it.” He and Katz envision waterways that are managed for flood control and farming but also for Chinook survival, ones with rice-field nurseries and bug farms to help restore self-sustaining salmon populations.\u003c/p>\n\u003cp>“It’s about welcoming the wild back into human landscapes in a way that makes sense,” Katz says. “We’re reimagining the system to work with nature.”\u003c/p>\n\u003c/div>\n\u003c/div>\n\u003c/div>\n\u003c/div>\n\u003c/div>\n\u003c/div>\n\u003c/div>\n\u003c/div>\n\u003c/div>\n\u003c/div>\n\n\u003c/div>\u003c/p>",

Maybe you’ve noticed what looks like spider webs woven between weeds along the trail, or poking out from under rocks or draped across logs.\u003c/p>\n\u003cp>But take a closer look – those webs might actually not be spider webs. A lot of them are silken habitats, known as galleries, created by insects called webspinners. While they’re usually underground or sequestered in burrows in fall and winter – you’re more likely to see the insects in early spring or summer – their silk is visible year-round in many parks and open spaces. They’re typically in areas that aren’t too wet or shady, nibbling on lichen, dead leaves and moss underneath their silken canopies.\u003c/p>\n\u003cfigure id=\"attachment_1949394\" class=\"wp-caption alignright\" style=\"max-width: 640px\">\u003cimg loading=\"lazy\" decoding=\"async\" class=\"wp-image-1949394 size-full\" src=\"https://ww2.kqed.org/app/uploads/sites/35/2019/10/Josh_Films_Silk_on_Log_With_Janice_Edgerly_Rooks-2.jpg\" alt=\"Santa Clara University professor of biology Janice Edgerly-Rooks and Deep Look producer Jenny Oh watch director of photography Josh Cassidy film webspinner silk at Guadalupe Oak Grove Park, San Jose, CA.\" width=\"640\" height=\"427\" srcset=\"https://cdn.kqed.org/wp-content/uploads/sites/35/2019/10/Josh_Films_Silk_on_Log_With_Janice_Edgerly_Rooks-2.jpg 640w, https://cdn.kqed.org/wp-content/uploads/sites/35/2019/10/Josh_Films_Silk_on_Log_With_Janice_Edgerly_Rooks-2-160x107.jpg 160w\" sizes=\"auto, (max-width: 640px) 100vw, 640px\">\u003cfigcaption class=\"wp-caption-text\">Santa Clara University professor of biology Janice Edgerly-Rooks and Deep Look producer Jenny Oh watch KQED director of photography Josh Cassidy film webspinner silk at Guadalupe Oak Grove Park in San Jose, California. \u003ccite>(Courtesy of Edward Rooks)\u003c/cite>\u003c/figcaption>\u003c/figure>\n\u003cp>“There are places where I go hiking where I just know their habitat looks perfect.

Maybe you’ve noticed what looks like spider webs woven between weeds along the trail, or poking out from under rocks or draped across logs.\u003c/p>\n\u003cp>But take a closer look – those webs might actually not be spider webs. A lot of them are silken habitats, known as galleries, created by insects called webspinners. While they’re usually underground or sequestered in burrows in fall and winter – you’re more likely to see the insects in early spring or summer – their silk is visible year-round in many parks and open spaces. They’re typically in areas that aren’t too wet or shady, nibbling on lichen, dead leaves and moss underneath their silken canopies.\u003c/p>\n\u003cfigure id=\"attachment_1949394\" class=\"wp-caption alignright\" style=\"max-width: 640px\">\u003cimg loading=\"lazy\" decoding=\"async\" class=\"wp-image-1949394 size-full\" src=\"https://ww2.kqed.org/app/uploads/sites/35/2019/10/Josh_Films_Silk_on_Log_With_Janice_Edgerly_Rooks-2.jpg\" alt=\"Santa Clara University professor of biology Janice Edgerly-Rooks and Deep Look producer Jenny Oh watch director of photography Josh Cassidy film webspinner silk at Guadalupe Oak Grove Park, San Jose, CA.\" width=\"640\" height=\"427\" srcset=\"https://cdn.kqed.org/wp-content/uploads/sites/35/2019/10/Josh_Films_Silk_on_Log_With_Janice_Edgerly_Rooks-2.jpg 640w, https://cdn.kqed.org/wp-content/uploads/sites/35/2019/10/Josh_Films_Silk_on_Log_With_Janice_Edgerly_Rooks-2-160x107.jpg 160w\" sizes=\"auto, (max-width: 640px) 100vw, 640px\">\u003cfigcaption class=\"wp-caption-text\">Santa Clara University professor of biology Janice Edgerly-Rooks and Deep Look producer Jenny Oh watch KQED director of photography Josh Cassidy film webspinner silk at Guadalupe Oak Grove Park in San Jose, California. \u003ccite>(Courtesy of Edward Rooks)\u003c/cite>\u003c/figcaption>\u003c/figure>\n\u003cp>“There are places where I go hiking where I just know their habitat looks perfect.

It’s these beautiful little bluish-tinted tubes.”\u003c/p>\n\u003cp>Webspinners, related to walking sticks and praying mantises, produce the finest silk in the animal kingdom. But unlike spiders, which produce silk from spinnerets on the tip of their abdomens, or caterpillars that produce it with salivary glands, webspinners have special silk ejectors on their front feet.\u003c/p>\n\u003cp>\u003c/p>\u003c/div>",

We’ve been watching it with this incredible microscope we have at the lab. We watch the water droplets dry, and it took more than twice as long for a tiny, tiny drop of water to disappear completely. Twice as long as if you put the tiny drop just on the counter.”\u003c/p>\n\u003cp>And while we typically think of silk as a beautiful, luxurious fabric, for the webspinners, it’s their homemade armor that protects them from predators. Since they’re soft-bodied with no other means of defense, they disappear into their habitat while ants and other predators just walk on top, unaware of their prey safely hidden below.\u003c/p>\n\u003cfigure id=\"attachment_1949391\" class=\"wp-caption alignleft\" style=\"max-width: 590px\">\u003cimg loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-1949391\" src=\"https://ww2.kqed.org/science/wp-content/uploads/sites/35/2019/10/rose.gif\" alt=\"Water drops on a silk compared to on a rose petal.\" width=\"590\" height=\"331\">\u003cfigcaption class=\"wp-caption-text\">Water drops on silk compared to on a rose petal. \u003ccite>(Courtesy of Janice Edgerly-Rooks / Josh Cassidy/KQED)\u003c/cite>\u003c/figcaption>\u003c/figure>\n\u003cp>They can also run away, but they have to run backward.\u003c/p>\n\u003cp>“It’s so funny to watch them walk. They’re totally compromised by having silk come out of their front feet,” said Edgerly-Rooks. “So when they walk forward, they walk on tiptoes just to make sure they don’t engage their silk ejectors. And they do not run forwards.”\u003c/p>\n\u003cp>In addition to her teaching duties, Edgerly-Rooks continues to study and raise webspinners she has collected around the world. She’s even \u003ca href=\"https://youtu.be/veehbMKjMgw\">composed music\u003c/a> inspired by these creatures’ movements.\u003c/p>\n\u003cp>And she advises that if you see them in the wild, be careful.\u003c/p>\n\u003cp>\u003c/p>\n\u003cp>“They are very fragile insects, so it’s not wise to try to pick them up,” she said. “You can maybe gather some of the silk tubes carefully with them inside the silk. If you put them in a small container, you can get them to run around for you, although some also play dead and are really good at ‘disappearing’ even when we know they are right in front of us.”\u003c/p>\n\n\u003c/div>\u003c/p>",
