Yesterday our attention was riveted by heroic efforts in the Highlands to re-wild, and today it is back to the sadder topic of un-wilding. Thanks to Rachel Nuwer for this article on a topic long of interest in these pages:
JAKARTA — In the market for a new pet? Maybe something a bit exotic? For many consumers, reptiles and amphibians are just the thing: geckos, monitors, pythons, tree frogs, boas, turtles and many more species are available in seemingly endless varieties, many brilliantly colored, some exceedingly rare.
Exotic reptiles and amphibians began surging in popularity in the early 1990s, not only in the United States but also in Europe and Japan. From 2004 to 2014, the European Union imported nearly 21 million of these animals; an estimated 4.7 million households in the United States owned at least one reptile in 2016.
But popularity has spawned an enormous illegal trade, conservationists say. Many reptiles sold as pets are said to have been bred in captivity, and sales of those animals are legal. In fact, many — perhaps most, depending on the species — were illegally captured in the wild. Continue reading →

Thanks to Kevin McKenna and the Guardian for this profile of an entrepreneurial conservation project that is quite in the spirit of our work over the last two decades. We salute Paul Lister and his team for this wonder:
The ‘custodian’ of the Alladale estate wants to turn it into a fenced-off wildlife reserve

The echoes of Scotland’s predator prince faded into silence three centuries ago. The wolf was once lord of these Sutherland slopes and the forest floors beneath and now a voice in the wilderness is calling him home.
Paul Lister acquired the Alladale estate, 50 miles north of Inverness, in 2003 and immediately set about creating a wilderness reserve according to his perception of what these wild and beautiful places ought to look like. He can’t imagine them without the packs of wolves that once roamed free here.
But his views are considered eccentric by ramblers and conservationists, who view them as a rich man’s caprice, centring their objections on his plans to fence off the vast reserve. Continue reading →
I get asked this often and I’m not always sure how to explain it to people without pictures at hand or infinite patience for follow-up questions. So, in this blog post, with the benefit of time to pick the right words and theoretically infinite space to write them out, I figured I would try to provide an adequate answer.
View from the field, a week or so ago
This, I feel, is the question at the crux of the what-do-you-do-every-day question. Why do you have to go to Kenya to do your work? Right, the bird you study is only found there, but why do you have to be out on the savanna everyday – can’t you just bring the birds back to the lab or study them in a zoo?
Of course, you can (nowadays, only with the right permits) and that is precisely what early zoologists did, collecting specimens – alive or dead – from around the world and bringing them back to examine them under microscopes or in aviaries in a rainy British country garden. While this may be convenient, it inevitably renders your conclusions about a bird’s diet or the adaptive nature of its plumage coloration suspect, because they are arrived at out of context. Without the bird having been examined in the environment it’s found in, with different factors that might affect its behavior and morphology in play, it is impossible to understand why it acts the way it does and why it is the way it is. Hence, fieldwork: observing and sampling critters in the wild. Continue reading →
We never think of evolution as particularly predictable. Surprising, yes. Awesome, yes. Predictable? Well, we love science for that reason, but still do not associate evolution with predictability. Thanks to Ed Yong, who enjoys making provocative statements that draw his reader in, for making evolution surprising in a new way:
On each Hawaiian island, stick spiders have evolved into the same basic forms—gold, white, and dark. It’s a stunning example of how predictable evolution can be.
Examples of white, dark, and gold species of stick spiders on various Hawaiian island. The top-left species is the most ancestral of them all. (Rosemary Gillespie et al.)
Most people go to Hawaii for the golden beaches, the turquoise seas, or the stunning weather. Rosemary Gillespie went for the spiders.
Situated around 2,400 miles from the nearest continent, the Hawaiian Islands are about as remote as it’s possible for islands to be. In the last 5 million years, they’ve been repeatedly colonized by far-traveling animals, which then diversified into dozens of new species. Honeycreeper birds, fruit flies, carnivorous caterpillars … all of these creatures reached Hawaii, and evolved into wondrous arrays of unique forms. Continue reading →
NASHVILLE — The snow was three inches deep, a blizzard by Nashville standards, when I got a text from a parent supervising the neighborhood sledding: “It’s a robin migration out in your front yard. Do you put food out there for them?”
I went to the window to look. There are nine bird feeders around my house, but I’ve never seen a robin at a single one of them. In winter, robins do gather in great flocks here in Middle Tennessee, and our yard is always popular with them because we have a birdbath with a heating element that keeps it from freezing. Even in winter, birds need to bathe — a seemingly counterintuitive behavior that keeps their feathers in shape for maximum insulation. Continue reading →
Protecting More Wilderness Map shows the scope of Tompkins Conservation park projects in Chile and Argentina. Eight Chilean parks, shown in boldface, comprise the latest expansion of wilderness areas, an area roughly twice the size of Massachusetts. Source: Tompkins Conservation. By The New York Times
We need a new story about the Earth that isn’t just a litany of alarming statistics about crashing wildlife populations, polluted air and water, and climate chaos. We need a story that reminds us that the continuing degradation of landscapes and the seas is not necessarily a one-way street toward irreversible destruction.
On Monday we began to write such a story with the government of Chile. Under the wide skies of the new Patagonia National Park, President Michelle Bachelet and I formalized the largest-ever expansion of a national park system prompted by a donation of private land. Continue reading →
CONGERS, N.Y. — Of all the coyotes that roam Dr. Davies Farm, looking for prey on this apple-picking orchard less than an hour from New York City, manager James Higgins says one of the pack stands out: Bigger and with more gray fur than its mates, this wolflike canine is a reason, Mr. Higgins says, there are fewer deer nibbling at Dr. Davies’s stock.
“We love having him here,” Mr. Higgins said as he drove around the property on an ad hoc coyote safari. There were no sightings, but Mr. Higgins ventured a profile of the creature: aloof, calm, uninterested in people.
“Anytime he sees any kind of human activity, he bolts,” Mr. Higgins said. “As long as he stays in his space and we stay in ours, everyone works in harmony.” Continue reading →
Efforts to protect biodiversity are now focusing less on preserving pristine areas and more on finding room for wildlife on the margins of human development. As urban areas keep expanding, it is increasingly the only way to allow species to survive.

One morning not long ago, in the southern Indian state of Karnataka, I traveled with a Wildlife Conservation Society biologist on a switchback route up and over the high ridge of the Western Ghats. Our itinerary loosely followed the corridor connecting Bhadra Tiger Reserve with Kudremakh National Park 30 miles to the south. Continue reading →
Since 2014, Washington’s Elwha River has flowed freely through what once was Lake Mills and the Glines Canyon Dam. But the site still leaves a barren scar in Olympic National Park. Now, a human- and bird-led effort is turning it green again.Photo:Elaine Thompson/AP
Conservation is sometimes in the hands of animals, as this story in the current Audubon magazine illustrates:
After the largest dam removal in U.S. history, scientists, Native Americans, and wild animals are working together to restore the heart of the Elwha.

It’s a scorching August day in the Elwha Valley, and it only feels bleaker as we peer into the 200-foot void of Glines Canyon Dam. A sputtering trail of water marks the concrete lip where, for nearly a century, two hulking braces trapped logs, rocks, and sediments as they washed down from the mountains of northern Washington, forming a reservoir that was six times deeper than a competition-diving pool. At its height, the dam churned out 13.3 megawatts of hydroelectricity, enough to power 14,000 homes and a local paper mill. But it also seriously altered the Elwha River’s ecology, along with that of surrounding Olympic National Park. Endangered chinook salmon were cut off from their spawning sites; fish-eating birds and otters suffered; and estuaries became more brackish and shallow. Finally, in 1992, the U.S. government issued the order to destroy Glines Canyon Dam and the nearby Elwha Dam. Yet it wasn’t until two decades later when the water was completely freed.

The rare oriental blue clearwing, that disguises itself as a bee, was spotted in the Malaysian rainforest
A moth that disguises itself as a bee and was previously only identified by a single damaged specimen collected in 1887 has been rediscovered in the Malaysian rainforest by a lepidopterist from Poland.
The oriental blue clearwing (Heterosphecia tawonoides) was seen “mud-puddling” – collecting salts and minerals from damp areas with its tongue-like proboscis – on the banks of a river in Malaysia’s lowland rainforest, one of the most wildlife-rich – and threatened – regions on Earth.

Dominick Solazzo likes to say the healthy dunes at Midway Beach and South Seaside Park on the Jersey Shore have a “secret ingredient.” Of course, it’s a secret that gives itself away pretty readily when the wind blows.
“It’s Christmas trees,” Solazzo says with a smile. Discarded (natural) Christmas trees donated by the city of Secaucus, New Jersey and given a second life – so to speak – as sand dunes. And, yes, according to him and a few of his neighbors, you can smell the sharp, familiar scent of fir through late winter and part of the spring.
But why Christmas trees? In a word: structure.
“They’re like re-bar in concrete,” explains Solazzo. “They help hold the sand and the dune in place, and give it structure. And good structure matters for dunes. It matters a lot.” Continue reading →
Previous efforts to restore former coal mine sites in Appalachia have left behind vast swaths of unproductive land. Now, a group of nonprofits and scientists are working to restore native trees to the region — even if it means starting the reclamation process from scratch.

Salviamo L’Orso is committed to conserving the critically endangered Marsican brown bear (pictured here in its central Apennines habitat), and has already won many grants for its grassroots projects. Bruno D’Amicis / Rewilding Europe
A Salviamo l’Orso project titled “Let’s take action for the Bear” was approved for funding by members of EOCA in early November, together with four other proposals from around the world.
With only 50 to 60 individuals remaining, all living in a relatively small area of the Central Apennines, the endemic Marsican brown bear (Ursus arctos marsicanus) is today critically endangered. The Salviamo l’Orso project, which comprises four conservation activities, will enhance the habitat of these magnificent animals and hopefully help them to expand their home range. Continue reading →
Yesterday’s post, linking to an article from the same source, combines with this one to confirm that some venerable members of the “mainstream media” see an audience (us, for example) for green-leaning reporting. Then we found this, about a remarkable Norwegian silence-hunter who has gone to the ends of the earth; and now finds himself in the East Village of New York City. Instead of featuring that story, this one below is must-read on the topic of quietude:
In the wilderness of Washington State’s Hoh Rain Forest, a poet searches for the rare peace that true silence can offer.
THE OLYMPIC NATIONAL PARK stretches down coastal Washington and east toward Seattle on a thumb of land known as the Olympic Peninsula, some 60 miles long by 90 miles wide. Around a three-hour ride by car from Seattle, it feels much farther, as if you have passed into an otherworldly realm. Within it are volcanic beaches scattered with the remains of massive Sitka spruces, evergreen-crowded mountains, broad, flat valleys and the Hoh Rain Forest, through which 12 miles of hiking trails and the glacier-formed Hoh River run. The Park, in total nearly a million acres, is home to what may be the most complex ecosystem in the United States, teeming with big-leaf maples, lichens, alders, liverworts, Monkey flowers, licorice ferns, club mosses, herbs, grasses and shrubs of remarkable abundance. Today, thanks to federal protections, it is home to some of the largest remaining stands of old-growth forest in the continental U.S. Continue reading →
IN ROCKS AND SOIL, air, ponds and oceans, life is dominated by creatures that humans cannot see. Microbes thrive everywhere, from gardens and kitchens to the harshest environments on the planet: under polar ice, in hydrothermal vents at the bottom of the sea, in hot springs that spew acid. A single gram of soil teems with billions of them, and their genetic diversity is equally impressive, dwarfing that of all the plants and animals on Earth. Life at the Edge of Sight: A Photographic Exploration of the Microbial World (forthcoming from The Belknap Press of Harvard University Press), brings the planet-shaping diversity of these single-celled, microscopic organisms into view through stunning images. Co-authors Roberto Kolter, professor of microbiology and immunology, and Scott Chimileski, a research fellow in microbiology and immunology at Harvard Medical School, share their passion for the subject in part by magnifying what cannot be seen unaided, in part by revealing large-scale microbial impacts on the landscape. Kolter has long been a leader in microbial science at Harvard, while Chimileski brings to his scholarship a talent for landscape, macro, and technical photography…
Read the whole article here, and if you happen to be in Cambridge (MA, USA) this exhibition might be of interest:
The minuscule ecosystem within a single drop of water is home to an astonishing diversity of organisms busily living out their lives and interconnected by myriad complex relationships. The photographic exhibit World in a Drop is an aesthetic journey into this microbial world, as revealed through cutting-edge imaging technologies. With expertly executed photography, videography, and poetic narration, Scott Chimileski and Roberto Kolter capture the intrinsic beauty of a mysterious world that is seldom recognized.
Whether or not you have been to Martha’s Vineyard, if you have been through our pages at all you will understand how this excerpt from the above book captures our attention and why we are interesting in tracking it down for a closer look:
The Vineyard landscape is distinct in many ways — most notably in land values, pace of development toward full build-out, the assemblages of plants and animals, and past success in land protection — but it typifies many qualities of Massachusetts and the greater New England region, including their conservation challenges. They share the history of agricultural and woodlot land use, the ongoing growth of their forests, the tension among farmed, open, and wooded lands, the relentless sprawl of development, the fragmentation of the land by many small, private landownerships, and the looming threats from climate change, sea level rise, insect outbreaks, and other stresses. Nevertheless, the Vineyard has put itself into a particularly strong position to address the looming challenges due to its expansive breadth of conserved lands, its forward-looking and Island-wide planning efforts and knowledge base about the landscape, and the capacity for ongoing land protection and stewardship.

From villain to hero, the jaguar (Panthera onca) stands at the cusp of a radical overhaul in its public image. As the largest cat in the Americas, the species commands a dominant role in the food chain of its native Pantanal – a vast swathe of tropical wetland that encompasses parts of Brazil, Paraguay and Bolivia. Once hunted for its fur, the jaguar’s appetite for the abundant prey in the Pantanal has led it into deadly conflict with ranchers in recent decades, casting it as the stalking menace of livestock and livelihood in a region where much of the land is reserved for cattle rearing. However, in a hopeful development for conservationists, researchers have revealed in a new study published in Global Ecology and Conservation that jaguars are worth 60 times more to tourism than the cost the big cats inflict on ranchers.
“The study represents a regional reality in the Pantanal,” said Fernando Tortato, research fellow at Panthera, the global wild cat conservation group that helped lead the study. “Where the jaguar brings in far more revenue than the potential damage it can cause.”
Jaguars once abounded from the southwestern U.S. to Argentina, but their numbers have fallen due to hunting and habitat loss. In the Amazon rainforest, deforestation is an ongoing threat, even while the dense foliage often precludes human encounters with jaguars. In the absence of benign tourism opportunities there is demand for jaguar teeth, paws and claws as souvenirs.
But jaguar’s predilection for lush and low-lying forest makes the Pantanal a stronghold for the species. The wetland’s web-like tributaries also open the wild cat’s home to human exploration, allowing tourists to share in their company.
In the Pantanal, the biggest threat to their survival is conflict with ranchers. Continue reading →
Economic value from trees is as old as mankind. Timber for homes and ships and all variety of implements. Nutritional value also: olives and their oil; figs; nuts. In the last year while in the forests of northwest Belize we were on the lookout for something new, something we had not yet known, something that would reveal new value within the forest; we had no clue what it might be. We were looking for the intersection between economic, nutritional and ecological value.
And finally a few months ago we came upon a nut that was new to us, and the trees it grows upon are particularly valuable from an ecosystem perspective. And an ethnobotanical perspective. So we are on the lookout for tree stories, especially those that overlap with themes we tend to in these pages–ecological, cultural and edible. We have linked to articles by Gabriel Popkin a couple of times previously, so we are not surprised by this editorial fitting our schema so well:
For several years, I’ve led tree walks in Washington, D.C. I start by asking participants who they are and why they want to spend precious hours looking at trees. My students are nearly all highly educated, successful people who work impressive jobs, speak multiple languages and effortlessly command sophisticated computers and phones. Yet most know barely the first thing about the trees around them. They want to change that. Continue reading →
In the 1980s, an ecologist named Thomas Lovejoy conducted an unusual experiment in Brazil’s Amazon rain forest. As loggers moved in with chain saws to clear trees for cattle pasture north of Manaus, he asked them to leave untouched several small “islands” of forest to see how the animals within them fared.
Two and a half years ago, the photographer Balarama Heller began venturing into the Florida Everglades at night, shining his flashlight and pushing through underbrush, in the hope of photographing an invasive predator that has disrupted the local ecology: the Burmese python. Continue reading →
