I acknowledge my enthusiasm for the idea that there is something going on between trees. I always want to hear more about it. Those who know me well joke that I am anti-woo-woo; but this one topic betrays a soft spot for the as-yet not fully explained. So I am thankful to Daniel Immerwahr for reminding me of the boundaries of what we know (so far):

Mother trees and socialist forests: is the ‘wood-wide web’ a fantasy?

In the past 10 years the idea that trees communicate with and look after each other has gained widespread currency. But have these claims outstripped the evidence?

There are a lot of humans. Teeming is perhaps an unkind word, but when 8 billion people cram themselves on to a planet that, three centuries before, held less than a tenth of that number, it seems apt. Eight billion hot-breathed individuals, downloading apps and piling into buses and shoving their plasticky waste into bins – it is a stupefying and occasionally sickening thought. Continue reading →

Tree house lodging is not new, but beyond beauty is impact. In that regard the accommodations with the most important view right now might be here:

The Highest Tree House in the Amazon

In 2023, conservationists and carpenters converged on Peru to build luxury accommodations in the rain-forest canopy.

Every day, empty logging trucks rumble into Puerto Lucerna, a small outpost on Peru’s Las Piedras River, which snakes through the lush Amazon rain forest. There, workers load them up with pyramids of freshly cut logs—cedar, quinilla, and, most important, ironwoods, which are prized for their hardness and rich color. Continue reading →

Of all the methods for addressing climate change, new incentives for protecting forests are among those we have most confidence in. Thanks to this article by Jo Chandler in Yale e360, if your introspection after reading this previous article had you down on carbon credits, there may be a way to restore your confidence:

Solomon Islands Tribes Sell Carbon Credits, Not Their Trees

In a South Pacific nation ravaged by logging, several tribes joined together to sell “high integrity” carbon credits on international markets. The project not only preserves their highly biodiverse rainforest, but it funnels life-changing income to Indigenous landowners.

The only sign of human habitation was below: a dirt circle surrounded by fanlike lean-tos made of wooden poles and palm fronds. It was a maloca, a traditional compound of the Yanomami, an Indigenous group that inhabits a remote territory in the rain forest of northern Brazil. Continue reading →

Forest Adaptation Via Scientific Methodology

Scientists in northern Minnesota are exploring how to adapt forests for climate change, transitioning them to a warmer future by planting new mixes of southern seedlings. In this “transition test” in the Cutfoot Experimental Forest, forest ecologists thinned trees and planted seedlings of eight species, grown from seeds collected up to hundreds of miles to the south.

Moving trees north to save the forests

As the world warms, trees in forests such as those in Minnesota will no longer be adapted to their local climates. That’s where assisted migration comes in.

On a brisk September morning, Brian Palik’s footfalls land quietly on a path in flickering light, beneath a red pine canopy in Minnesota’s iconic Northwoods. A mature red pine, also called Norway pine, is a tall, straight overstory tree that thrives in cold winters and cool summers. It’s the official Minnesota state tree and a valued target of its timber industry.

But red pine’s days of dominance here could fade. In coming decades, climate change will make red pine and other Northwoods trees increasingly vulnerable to destructive combinations of longer, warmer summers and less extremely cold winters, as well as droughts, windstorms, wildfires and insect infestations. Climate change is altering ecological conditions in cold regions faster than trees can adapt or migrate. Continue reading →

Thanks to Cara Buckley for another in her long line of tree stories:

Coming Soon to Manhattan, a Brand-New Tiny Forest

Pocket-size forests filled with native plants have been embraced worldwide for their environmental benefits. Now one is planned for New York City.

A trend that’s gaining momentum around the world is set to finally arrive in Manhattan. It’s a tiny forest, to be planted on the southern end of Roosevelt Island, in the East River, this spring. According to its creators, it would be the first of its kind in the city and would consist of 1,000 native plants, trees and shrubs, covering just 2,700 square feet. Continue reading →

Planting trees, we have noted, is smart policy.  Some campaigns may have stretched beyond scientific evidence, but science has given us plenty to go on:

Very cool: trees stalling effects of global heating in eastern US, study finds

Vast reforestation a major reason for ‘warming hole’ across parts of US where temperatures have flatlined or cooled

Trees provide innumerable benefits to the world, from food to shelter to oxygen, but researchers have now found their dramatic rebound in the eastern US has delivered a further, stunning feat – the curtailing of the soaring temperatures caused by the climate crisis.

While the US, like the rest of the world, has heated up since industrial times due to the burning of fossil fuels, scientists have long been puzzled by a so-called “warming hole” over parts of the US south-east where temperatures have flatlined, or even cooled, despite the unmistakable broader warming trend.

Dickson D. Despommier Discussing The New City Concept

/ Organikos / Leave a comment

The vertical farming part of this concept is one we have linked to many times. The appeal is not difficult to grasp even if sometimes the concept is stretched. This is different and worth hearing him out:

Dickson Despommier Wants Our Cities to Be Like Forests

A leading proponent of vertical farming discusses how urban areas should adapt to a perilous environmental future.

Illustration by Daniele Castellano

In 2000, Dickson D. Despommier, then a professor of public health and microbiology at Columbia University, was teaching a class on medical ecology in which he asked his students, “What will the world be like in 2050?,” and a follow-up, “What would you like the world to be like in 2050?” As Despommier told The New Yorker’s Ian Frazier in 2017, his students “decided that by 2050 the planet will be really crowded, with eight or nine billion people, and they wanted New York City to be able to feed its population entirely on crops grown within its own geographic limit.” Continue reading →

Female Rangers ‘Don’t Go All Alpha Like the Men’ to Protect a Forest

Rather than take a confrontational approach with trespassers looking to farm or log in a tropical rainforest in Indonesia, teams of women rangers try dialogue first.

Asmia, one of 15 rangers whose job is to protect nearby forests from squatters who want to clear trees for timber or to farm the fertile soil.

Riding her motorbike while balancing a backpack, a wok and a sharp cleaver, Asmia expertly maneuvered her way up a dangerous cliffside: a three-mile trip along a precipitous dirt path, barely 40 inches wide, to reach the mouth of the forest.

Asmia is one of the 15 members of a team of rangers — 10 of whom are women — whose job is to protect their village forest in Aceh Province in Indonesia from the squatters who want to clear the trees for timber or to farm the fertile soil.

Two teams of rangers, each consisting of five women and two men, take turns each month on five-day forest patrols.

“Here, we once fought with a squatter, asking him to stop the encroachment,” Asmia said, pointing as she walked beneath the thick canopy of trees that shadow her rounds. “He insisted on clearing the land, as he wanted to grow coffee. He was persistent. But we talked him out of it.” Continue reading →

Fungi & Fireproofing

/ Organikos / Leave a comment

Mycologist Zach Hedstrom sprays a spore-infused liquid to inoculate debris from forest thinning.

Inside Boulder Mushroom’s laboratory, a refrigerator houses an array of agar plates containing diverse mycelium cultures.

We have paid attention to mycological wonders for long enough that surprises are rare; but they happen. Stephen Robert Miller’s reporting, with photography by Jimena Peck were published in the Washington Post and came to our attention by way of the Food & Environment Reporting Network, which is where you can read the entire article:

How mushrooms can prevent megafires

Thinning forests to prevent fires produces a lot of sticks and other debris, which also pose a fire risk. In Colorado and elsewhere, scientists are using fungi to turn those trimmings into soil.

Overgrown stands of lodgepole pine are a risk for megafires. Thinning the stands simulates the effects of a natural fire but also generates a large amount of biomass, called “slash,” which can also fuel forest fires.

If you’ve gone walking in the woods out West lately, you might have encountered a pile of sticks. Or perhaps hundreds of them, heaped as high as your head and strewn about the forest like Viking funeral pyres awaiting a flame.

These slash piles are an increasingly common sight in the American West, as land managers work to thin out unnaturally dense sections of forests — the result of a commitment to fire suppression that has inadvertently increased the risk of devastating megafires. Continue reading →

Beechnut & Beaver Hope

Nearing the end of the northern summer, one for too many of the wrong kind of record books, some notion of hope is more than welcome. This edition of his newsletter offers some:

Beavering Away

In the guise of my annual report on our nifty online community I’m going to show you my vacation pictures! Lucky you!

It’s possible I’m just feeling guilty because I took a couple of days off in this Summer To End All Summers. But Sunday and Monday, while Hillary was introducing southern Californians below the age of 85 to the concept of ‘tropical storm,’ I went on a wander with an old friend through the middle of the Wilcox Lake Wild Forest in New York’s Adirondack Mountains, a splendidly remote chunk of land that I’ve lived on the edge of, off and on, for much of my life, and which I never tire of exploring.

The photograph heading the story is alarming enough, but the illustrations (especially the “scroll down” graphic) accompanying the written explanations are extremely compelling. Thanks to Benji Jones for the story and to Alvin Chang for the graphics in this Vox article:

The alarming decline of Earth’s forests, in 4 charts

Deforestation raged ahead again in 2022, even after scores of countries pledged to protect their forests.

Over the last decade, dozens of companies and nearly all large countries have vowed to stop demolishing forests, a practice that destroys entire communities of wildlife and pollutes the air with enormous amounts of carbon dioxide.

A big climate conference in Glasgow, in the fall of 2021, produced the most significant pledge to date: 145 countries, including Brazil, China, and Indonesia, committed to “halt and reverse” forest loss within the decade. Never before, it seems, has the world been this dedicated to stopping deforestation. Continue reading →

More On Merlin Sheldrake, Fungi & Related Matters

Merlin Sheldrake, author of the best-selling book “Entangled Life.” Alexander Coggin for The New York Times

We are grateful to any publication that gives this topic its due attention, in this case the New York Times and a particular thanks to Jennifer Kahn for such a thoughtfully written profile:

A vast fungal web braids together life on Earth. Merlin Sheldrake wants to help us see it.

One evening last winter, Merlin Sheldrake, the mycologist and author of the best-selling book “Entangled Life,” was headlining an event in London’s Soho. The night was billed as a “salon,” and the crowd, which included the novelist Edward St. Aubyn, was elegant and arty, with lots of leggy women in black tights and men in perfectly draped camel’s-hair coats. “Entangled Life” is a scientific study of all things fungal that reads like a fairy tale, and since the book’s publication in 2020, Sheldrake has become a coveted speaker.

A pied bleu (Lepista personata), also known as the field blewit. Alexander Coggin for The New York Times

At talks like these, Sheldrake is sometimes asked to answer a question he poses in the first chapter of his book: What is it like to be a fungus? The answer, at least according to Sheldrake, is at once alien and wondrous. “If you had no head, no heart, no center of operations,” he began. “If you could taste with your whole body. If you could take a fragment of your toe or your hair and it would grow into a new you — and hundreds of these new yous could fuse together into some impossibly large togetherness. And when you wanted to get around, you would produce spores, this little condensed part of you that could travel in the air.” There were nods. In the audience, the woman next to me gave a long, affirming hum. Continue reading →

Trees Are Always Welcome In Our Pages

Jill Lepore gives us a 30-minute read on a topic we have linked to more times than any topic other than birds:

What We Owe Our Trees

Forests fed us, housed us, and made our way of life possible. But they can’t save us if we can’t save them.

The woods I know best, love best, are made of Northern hardwoods, sugar maple and white ash, timber-tall; black and yellow birch, tiger-skinned; seedlings and saplings of blighted beech and striped maple creeping up, knock-kneed, from a forest floor of princess pine and Christmas fern, shag-rugged. White-tailed deer dart through softwood stands of pine and hemlock, bucks and does, the last leaping fawn, leaving tracks that look like tiny human lungs, trails that people can only ever see in the snow, even though, long after snowmelt, dogs can smell them, tracking, snuffling, shuddering with the thrill of the hunt and noshing on deer scat for dog treats.

The Forest Gives Much

Freshly harvested logs from the Menominee Forest in Keshena, Wis., marked with color to indicate each log’s grade.

Sustainable forestry is a long-running topic in these pages over the years. The previous times we have linked to Cara Buckley stories we have been enriched by the humanity in environmental stories, so here we combine her unique talent to the topic of forestry:

The Giving Forest

The Menominee tribe has sustainably logged its forest in Wisconsin for 160 years. But that careful balance faces a crisis: too many trees and too few loggers.

A tree marked for cutting. The Menominee harvest only trees that are sick and dying or those that have fallen naturally

MENOMINEE COUNTY, Wis. — Amid the sprawling farmlands of northeast Wisconsin, the Menominee forest feels like an elixir, and a marvel. Its trees press in, towering and close, softening the air, a dense emerald wilderness that’s home to wolves, bears, otters, warblers and hawks, and that shows little hint of human hands.

Yet over the last 160 years, much of this forest has been chopped down and regrown nearly three times. The Menominee Tribe of Wisconsin, its stewards, have pulled nearly two hundred million cubic feet of timber from this land since 1854 — white pine cut into museum displays and hard maple made into basketball courts for the Olympics.
