From National Audubon Society:

Rapidly Declining Songbird Won’t See Federal Protections Anytime Soon

The U.S. Fish and Wildlife Service has delayed its decision on the Saltmarsh Sparrow’s endangered status to 2023. Scientists say that might be too late.

By Purbita Saha
Associate Editor, Audubon Magazine
May 24, 2019

Greg Shriver and Chris Elphick have spent the last decade agonizing over the Saltmarsh Sparrow’s extinction. Both ecologists began studying the scrappy, sherbert-faced bird in the mid-2000s to better understand how its nesting habits revolve around the shoreline grasses and ebbing tides of the Atlantic. Both soon realized that their uniquely adapted subject wouldn’t survive the next century, due to intensifying flooding, predation, and development along its East Coast range.

Elphick and Shriver’s analyses showed a yearly 9 percent decline in the sparrow’s population—enough, they believed, to warrant consideration for federal protections. So, in 2017, they took all the evidence they’d amassed with the Saltmarsh Habitat and Avian Research Program and made their case with the U.S. Fish and Wildlife Service (USFWS). The agency agreed to kick off the decision-making process in 2019; but last month it suddenly switched course and said it would put off reviewing the sparrow for an endangered species listing until 2023, according to scientists present at the announcement.

“The 2023 time will allow us to incorporate additional information about management efforts that are at an early stage,” confirms Meagan Racey, public affairs specialist for USFWS, Northeast Region. She adds that the agency may reconsider the revised schedule if circumstances around the species become more urgent.

The data USFWS is looking for will come from the Atlantic Coast Joint Venture, an independent network of federal and state wildlife departments, nonprofits like Audubon, and researchers like Shriver and Elphick focused on protecting marine marshes and their birds. The initiative, which launched back in 2016, is funded by the agency but holds no clout when it comes to endangered species listings, says Aimee Weldon, its coordinator.

This summer the venture will release an action plan that outlines ways to help Saltmarsh Sparrows cope with sea level rise on the most affected parts of the coast. USFWS says it will wrap the venture’s suggestions, which include building tide gates, digging connector creeks to drain floodwaters, and shaping restoration around shifts in the bird’s habitat, along with a pending business plan, into its own work to establish a Saltmarsh Sparrow program. Whether that vision will actually be funded and executed before 2023 still remains a question. “We have had a lot of discussions,” Elphick says. “But in terms of actually spending money to do anything, we haven’t witnessed much.”

Experts like Shriver and Elphick contend that the extended timeline makes the sparrow’s situation more precarious, pointing out that the species is already classified as endangered by the IUCN Red List (a nominal label only). “There won’t be any new information by 2023,” says Shriver, who recently co-authored a paper on how nest predators are wiping out New Jersey's largest Saltmarsh Sparrow population. “We will have just lost more birds.” He thinks the agency is trying to punt the verdict to an administration that will be less hostile to expanding the endangered species list.

The four-year window also has other limitations. For one, Elphick says, it doesn’t give USFWS enough time to weigh outcomes from field testing and pilot projects. “Cutting down trees to see if marshes will migrate inland, raising entire nesting sites—you don’t collect immediate results,” he explains. “Maybe we can wait another decade for that insight, but Saltmarsh Sparrows could be extinct in a decade and a half.”

With so many uncertainties in the pending proposals and plans, the Endangered Species Act, in many scientists’ opinion, is still the clearest answer for the bird’s myriad problems. “While I have confidence in the Atlantic Coast Joint Venture, the Saltmarsh Sparrow needs a broader, concerted conservation effort,” says Walker Golder, Audubon’s Atlantic Flyway program director. He notes that a listing will lead to more wherewithal and attention for restoration; without it, conservationists don't have the power to respond quickly to threats such as sea level rise, predation, and habitat loss.

Like in New York City, for example. In 2015 birders discovered that one of the few Saltmarsh Sparrow nesting spots in the area had been flattened by a contractor hired by the parks department. The landscape never was replanted, and the breeding population never returned. “An endangered-species status would protect these kinds of saltmarshes,” Alison Kocek, an ornithologist who was banding the inhabitants at the site, said at the time. “If we lose another one, we don’t know what will happen.”

Weldon agrees that every last stronghold is valuable. “We need to work very fast. Even if we don’t have the time, we’re going to try and throw everything we can at [the Saltmarsh Sparrow’s decline],” she says. Elphick and his colleagues are mobilizing, too, in spite of the USFWS setback: They’re running a species-wide survey in 2021 to learn just how many individuals are left between Florida and Maine.

And if the sparrow is past redemption—what then? “If we aren’t successful in saving the species, our efforts will still be important for other tidal marsh birds,” Weldon says. But knowing there's a law that could prevent that outcome just waiting in the wings will continue to frustrate researchers over these next four years. ...Read more

From Earther.gizmodo.com:

An Estimated 414 Million Pieces of Plastic Have Piled Up on Australia's Best Beaches
Brian Kahn
May 20, 2019

Human trash continues to pile up on every corner of the Earth at an alarming rate. And new research published on Thursday in Scientific Reports chronicles yet another frontier in our increasing plastic pollution crisis.

Researchers looked at the Coco (Keeling) Islands, two small islands to the west of Australia with some of the best beaches in the country, and found those pristine locales are smothered in plastic. The researchers estimate that their soft yellow sand is now littered with an astounding 414 million piece of plastic, all of it washed up from far away lands. And with no way to clean up that much debris, the findings show single use lifestyles are rapidly wiping out nature.

Jennifer Lavers, a plastic researcher at the University of Tasmania who led the study, had previously done work on extremely remote atolls. But she told Earther she wanted to look at a place a little closer to home so people could truly understand how big the scope of the plastic problem is. When an opportunity to visit the Coco (Keeling) Islands with activist organization Sea Shepherd arose, she took it as a chance to do some research there.

To get their plastic estimate, Lavers and her team took samples along 15 transects on the beaches from the water’s edge to the start of vegetation. They dug up 10 centimeters (4 inches) of sand at various points along those transects and cataloged how much plastic debris they found. The surveys turned up 23,227 pieces of plastic.

On its own, that’s a lot of plastic. But the researchers then extrapolated out for the islands as a whole and found that the two tiny islands islands are home to an estimated 414 million pieces of plastic. Of that, 383 million pieces sit below the surface, forming a new kind of bedrock.

“In my 15 years working as a marine scientist and traveling to some of the remotest corners of this planet, I sometimes feel like nothing surprises me anymore,” Lavers said. “Certainly, I’ve grown to expect plastic, and lots of it, everywhere I go. But the quantity of plastic on the otherwise remarkable and pristine Cocos (Keeling) Islands is truly devastating. The human footprint is everywhere, and it runs deeper than most of us imagine.”

Lavers said when writing the paper, “we put out a call to other scientists and friends for other remote, sparsely inhabited places with high accumulation of plastic debris.” They found similar stories playing out on islands around the world. While there are plenty of clearly identifiable pieces of junk and single-use items on Cocos (Keeling) Islands and other remote locations, much of the plastic consists of bits and pieces that have been broken down by arduous trips across the ocean. Because plastic can take centuries to degrade, these pieces won’t go away but will instead just get smaller and smaller.

That breakdown means that the tiny bits of plastic can end up nearly anywhere, from tropical islands to the Arctic. It evens up blowing in the air around us and the water we drink.

Cleaning up these bits and pieces is hard to do without disrupting the environment. That doesn’t mean we shouldn’t try to do it, but it points to the urgent need to turn away from plastic and disposable lifestyles. There are some signs the tide is turning against plastic like the European Union’s single-use ban, but as the paper notes, half of all plastic the world has produced has been made in the past 13 years alone. So there’s still a long way to go.

Plastic wasn't born to be recycled.

Ever since 1909, when chemist Leo Baekeland developed Bakelite — the first real synthetic, mass-produced plastic — scientists have relied on an entirely unnatural process for making the stuff.

Before then, scientists were trying to make a durable, light material using rubber latex from plants or shellac from beetle secretions. Even celluloid was made mostly from plant cellulose.

But while crude oil remains a key component, plastic just has too many other prickly chemical properties to go easily back to the earth from whence it came. Blame it on additives — dyes, fillers and flame retardants.

All this may account for our woeful inability to control it today.

But scientists at Berkeley Labs have developed a new strain of plastic that they say has all the vaunted properties of modern polymers — but also happens to be 100 percent recyclable.

In a study published in April in Nature Chemistry, the team describes a new type of plastic that can be broken down at the molecular level. As a result, that plastic can be fully recovered and made into new items as pristine as the original.

"Most plastics were never made to be recycled," lead author Peter Christensen from Berkeley Lab's Molecular Foundry noted in a statement. "But we have discovered a new way to assemble plastics that takes recycling into consideration from a molecular perspective."

If you had a recycling bin full of items made from that new plastic, all of it would end up in someone else's recycling bin and then someone else's bin forever and ever.

Of course, the key would be to make sure it ends up in that bin. Rather than, say, the Indian Ocean. At the very least, the Berkeley team suggests, the new plastic could dramatically ease the burden on landfills and even make the all-too complicated business of recycling a lot smoother.

Why current plastics are so hard to recycle

A big reason why recycling often falls short, the researchers note, is due to the additives. The recycling process is often gummed up by chemicals that stick to monomers — the small compounds that fuse to become polymers. As such, it's hard to scrub those polymers clean at the recycling plant. Ultimately, plastics with differing chemical compositions are all lumped together at the plant, making it impossible to predict what the recycled product will look like.

And, as the team notes in the release, durability of that recycled product suffers. Plastic doesn't get a lot of rides on the recycling train before it becomes essentially useless.

Enter the new plastic — a material the Berkeley team dubs polydiketoenamine, or PDK. Unlike the traditional stuff, an acid bath is all that's needed to scrub its monomers clean from all those clingy additives. From there, those basic monomers form the building blocks of the next plastic product — whether it's a water bottle or a kid's lunch pail. Because the plastic is broken down into its most basic components, and built up again, there is no loss in quality or durability.

Recycling could actually become the perfect circle it was envisioned to be.

"This is an exciting time to start thinking about how to design both materials and recycling facilities to enable circular plastics," one of the study authors, Brett Helms, notes in the release.

Could there really be a great future in plastics — again?

The trick will be to get PDK out of a Berkeley lab and into circulation, a daunting but increasingly urgent proposition considering the toll traditional plastic is taking on our planet.

But the researchers say this plastic won't be released into the wild just yet. They're working on adding natural materials to PDK, hoping to make it not only strong and durable but greener.

Full circle indeed. ...Read more

3rd Annual Horseshoe Crab Festival at Jamaica Bay
With American Littoral Society, Gateway National Recreation Area
Join us for a day of celebrating the annual arrival of horseshoe crabs to our local shores. During the full and new moons of May and June, these prehistoric animals, which date back approximately 400 million years, come ashore to mate. The females lay billions of eggs at the high tide line each season. At the same time, thousands of migrating shorebirds arrive in the northeast bays to feed on the eggs, regaining the body weight they lost during their long journey north. At the festival you’ll see and hold live horseshoe crabs and learn about their important ecological and medicinal values. For more information on the festival, contact the American Littoral Society at 718-474-0896 or email Don Riepe at donriepe@gmail.com.
The program is free, but suggested donations of $20 for adults and $10 for children to NYC Audubon are suggested to offset the festival cost. No registration required.

When the Internet Lets Us Love Nature a Little Too Much
April Glaser
April 04, 2019

Our enthusiasm for sharing birds, plants, and superblooms has unintended consequences. But we can use the same tools that made the problem to fix it.

Birders like to make lists. The other day, just walking by the lake in Oakland, California, I saw an Anna’s hummingbird, a couple different types of finches, grebes, sparrows, a kingfisher, a great blue heron, and an egret. Soon, I plan to upload that list to eBird, the online bird-watching community based out of Cornell University, which is the largest citizen science open data archive in the world. None of these species are particularly threatened, so I feel good about sharing my list. But had I been in a region where birds are struggling for their lives and I spotted a threatened species, like the violet-necked lory of Indonesia, the Dulit frogmouth of Borneo, or the golden-winged laughing thrush of Vietnam, I would think twice before posting those findings to an app with nearly half a million other eBirders who have clocked some 590 million bird observations since the project started in 2002.

The whole point of eBird is to share birding data, so that other birders can enjoy the same delights. But a couple years ago, in October 2017, the project under went one of the largest overhauls to its code to date: The database started hiding birds entered into its system that were endangered and threatened. “Basically, the whole database had been built to share bird data and show it publicly on maps,” Marshall Iliff, a project leader at eBird, told me in an interview. “We put basically 10 years of development and PR behind asking users to show us exactly where they found the birds, so it’d be most useful for science. And suddenly we were in this situation where we realized we have to hide certain birds.”

When it comes to enjoying nature in real life, most people’s intention in sharing their experiences online is to celebrate it. But these increasingly ubiquitous acts are also opening the door to abuse. Apps and databases made for identifying and mapping native plants and birds have had to rebuild their infrastructure in recent years to obfuscate endangered species.
It’s the only way to protect them from poachers who are savvy enough to take advantage of the citizen science open data projects and nature forums where enthusiasts share photos and locations of plants and animals with fellow nature lovers.

Though Iliff says he hasn’t heard specific reports of eBird data being used by poachers, with open data it’s pretty hard to know what people who access the information do with it. “We do know that there were anecdotal reports of people in Indonesian markets saying that some of the bird trappers were familiar with eBird and pull it up on their phone to say, ‘This is where the bird lives,’ ” Iliff sighed, adding that the poachers were also reportedly savvy about downloading birdsongs from other websites, like xeno-canto.org, a bird sound database that likewise takes precautions to protect sensitive species. The market incentivizes the poachers—the beak of the helmeted hornbill in Indonesia, for example, with its red rubbery neck, remarkably expressive eyes, and prized casque that resembles ivory, can sell for thousands of dollars. Now, after the changes, birdwatchers can log data for the helmeted hornbill, but it’s not sharable.

Thanks to the well-meaning efforts of citizen scientists and open data projects, what in a previous generation may have taken poachers years to map can now be downloaded in minutes.

Closing select parts of a fundamentally open platform wasn’t easy. Over the course of about eight months, eBird built in features that allowed a person who entered the data of a protected species to see it, as well as eBird’s data review team, but no one else. EBird flags birds that are on its Sensitive Species List, which are at risk of being captured, targeted, and killed, or are at risk of detrimental disturbance in specific locations. There are hundreds of birds listed as sensitive. When a threatened species is logged, it’ll show that the bird is within a 20-kilometer area but won’t allow users to drill down to the specific location of the sighting. And if you share your bird list with a friend, only you’ll be able to see the endangered species you recorded—they won’t show up on the shared list. The same goes with photos of threatened birds and other tools that eBird has built to share bird spotting data.

It’s not only birds that need privacy online. In 2015, a Spanish husband and wife team were arrested after a park ranger found them with a pickup truck just outside the remote Knersvlakte Nature Reserve near the central west coast of South Africa. When a ranger asked to look in the couple’s backpacks, she found 49 of the miniature succulents that grow between the quartz that blankets the arid flatland. The couple, it turns out, was anonymously operating a website, africansucculents.eu, where they sold poached plants, according to a report from Yale Environment 360. The Knersvlakte is one of the richest succulent diversity zones in the world, with 1,500 species of plants, including more than 150 that are threatened with extinction.

Back at the succulent thieves’ guest room, authorities discovered more than 2,200 succulents worth around $100,000. Beyond the thousands of plants, hundreds of which were threatened species, the couple’s room was also packed with pages of research. There were reportedly pictures and detailed maps printed from social media and the online citizen science database iSpot, as well as pages from the digital museum project JSTOR Global Plants. Thanks to the well-meaning efforts of citizen scientists and open data projects, what in a previous generation may have taken poachers years to map can now be downloaded in minutes.

In recent years, other wildlife data projects that opened with the primary intention of sharing as much data on the natural world as possible have started to batten down, too. INaturalist, a citizen science portal that records sightings of all kinds of wildlife, from plants to birds to insects and fish, started hiding endangered taxa in 2011, though Ken-ichi Ueda, one of the founders and directors of iNaturalist, told me it was a problem they considered since starting in 2008. Today, iNaturalist logs about 135,000 observations a month, of which about 4,600 obscure the location data because the wildlife is marked as threatened. The push to hide plants and animals that are at risk, Ueda says, was driven by the launch of a project on iNaturalist called the Global Amphibian BioBlitz that encourages sharing citizen data of amphibians around the world by gamifying the observations and highlighting users who log the most. So far, more than 11,000 identifiers have logged in nearly 300,000 observations. Before the project launched, Ueda told me that many of the groups iNaturalist was partnering with in the world of amphibian conservation, including the International Union for Conservation of Nature, were concerned that the project wasn’t hiding location data and asked that the database be built in a way to obscure the coordinates of threatened wildlife before they collaborated.

Hiding data puts open data projects in an obvious bind. “A great deal of what I have learned about the natural history of California comes from information others have shared in public on the internet, and one of my purposes in developing iNaturalist was to facilitate the same kind of sharing so others could learn as I have,” Ueda commented on a Facebook post I made asking about how citizen science projects grapple with threatened species on the California Native Plant Society group. “Hiding the locations of threatened species is ultimately about hiding information, not sharing it, so I think it’s important for everyone to understand there’s a tradeoff: the more you hide, the less you share, and the less useful the information becomes.”

Databases for nature obsessives aren’t the only way our online habits threaten wildlife. Virality on social media can be deadly as well. The wildflowers of Southern California are so stunning this year they’re causing what Lake Elsinore officials are calling “a public safety crisis.” Hundreds of thousands of people have descended on the small Southern California city to photograph the rare cascade of poppies that paints the hillsides with delicate apricot flowers. The mania is sparked by enviable Instagram posts of people frolicking in the bloom, likely crushing flowers underfoot as they venture, against the advisement of the park rangers, off trail to get that perfect shot drenched in California sunshine. A couple even flew a helicopter into a field of poppies recently at the Antelope Valley Poppy Reserve to take a hike—likely killing hundreds of the beautiful buds visitors exactly like them would wish to see upon landing. “We have brought in all available staff, as many outside traffic controllers that we could, more shuttles, and our small City cannot sustain crowds of this magnitude,” read a recent post on the Facebook page of Lake Elsinore City Hall. The mayor of Lake Elsinore dubbed the uncontrollable throngs of flower tourists a “Poppy Apocalypse” and last month the city even had to shut down two interstate ramps to keep tourists away, announcing the closures on Instagram with the hashtags #Poppyshutdown, #IsItOver, and #PoppyNightmare.

There’s something just a little too 2019 about the internet finding a way to ruin wildflowers. But all of this is an inevitable consequence of how online our lives have become. The internet is perhaps best at making the world seem so much smaller than it really is. The popularization of natural wonders, like California’s superbloom, fueled by sun dappled photos on Facebook and Instagram, attracting thousands of onlookers and social media influencers who step on the flowers, scratches at a larger question how we can revel in nature without inadvertently ruining it. When we share an image online of a place or a bird or a flower that we love, we are sharing our experience with it. But even as we aim to spread beauty, we must also reckon with the truth about the human-induced fragility of our ever-deteriorating natural world. And that might sometimes mean not sharing everything.

Northern California is currently in the midst of a succulent poaching crisis of its own. The crown jewels the thieves are after are the Dudleya farinosa, a thick-leafed roseate flushed with pink tips and a bizarre flowering yellow stalk that towers from its center. When mature, the plants can fetch as much $100 where they’re currently in vogue in South Korea, where people display them as a windowsill decoration. That’s why they’re being plundered by poachers who often fly in, load up on cardboard boxes, snag a hotel room, and spend their days digging up succulents off oceanside cliffs. Stephen McCabe, a dudleya expert and emeritus director of research for the UC–Santa Cruz Arboretum, told me that thousands are being pulled from the ground a month. Many are decades old—some are as old as a 100.
