Bison restoration stories we have linked to are mostly in North America. But the Carpathian mountains have demonstrated Romania’s outsized efforts at rewilding. Now the largest such effort in Europe, according to Rewilding Europe, is this:

The goal of the Tarcu Mountains bison initiative is to help build a herd of at least 500 bison living in freedom by 2025 in the Southern Carpathians. This is an area spanning some 1.4 million hectares of wild mountains and valleys in the southern part of the Carpathian mountain chain.

How a Small Herd of Romanian Bison Is Locking Away Thousands of Tons of Carbon

Gone from Romania for 200 years, European bison were reintroduced to the Țarcu Mountains, at the southern end of the Carpathian range, in 2014. Now numbering 170, the bison are reshaping the mountain landscape in ways that are helping clean up emissions. Continue reading →

Marsh Matters

/ Organikos / Leave a comment

Coastal marshlands exist in a precarious state: they need enough sediment to stay above water but not so much they get buried. In San Francisco Bay, the US Army Corps of Engineers and others are working to develop a less destructive way of giving marshes the mud they need. Photo by Aerial Archives/Alamy Stock Photo

For the record, marshes matter, so our thanks to Erica Gies, writing for Hakai:

Making a Marsh out of a Mud Pile

In San Francisco Bay, scientists are looking for a better way to rebuild flagging marshland.

The water in California’s San Francisco Bay could rise more than two meters by the year 2100. For the region’s tidal marshes and their inhabitants, such as the endangered Ridgway’s rail and the salt marsh harvest mouse, it’s a potential death sentence. Continue reading →

Assisted Evolution

If conservation failure is an option, then assisted evolution is a necessary consideration. Emily Anthes walks us through the idea:

When traditional conservation fails, science is using “assisted evolution” to give vulnerable wildlife a chance.

Scientists are trying to save lowland Leadbeater’s possums, tree-dwelling marsupials known as forest fairies, by crossbreeding them with possums from a separate highland population, a strategy known as genetic rescue.

For tens of millions of years, Australia has been a playground for evolution, and the land Down Under lays claim to some of the most remarkable creatures on Earth.

It is the birthplace of songbirds, the land of egg-laying mammals and the world capital of pouch-bearing marsupials, a group that encompasses far more than just koalas and kangaroos. (Behold the bilby and the bettong!) Nearly half of the continent’s birds and roughly 90 percent of its mammals, reptiles and frogs are found nowhere else on the planet.

Australia has also become a case study in what happens when people push biodiversity to the brink. Continue reading →

Illegal Miners Face The Fire

In a clearing in the Brazilian Amazon, I stood with a group of armed men, discussing a viral TikTok video.

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

/ Organikos / Leave a comment

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 →

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 →

A Century’s Evidence On The Benefits Of Planting Trees

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.

Golf is known to be problematic. But then again, what is not problematic? And we appreciate seeing cases where golf gives way to nature. Our thanks to Cara Buckley for bringing this story to our attention in the New York Times. We applaud the imagination of those responsible:

After Shutting Down, These Golf Courses Went Wild

Most defunct golf courses get paved over, but a number are getting transformed into ecological life rafts for wildlife, plants — and people.

There was scraggly grass in one sand trap and wooden blocks and a toy castle in another, evidence of children at play. People were walking their dogs on the fairway, which was looking rather ragged and unkempt. This was only to be expected. Continue reading →

Along with anything else to get 2024 off to a good start, an article by Andrew Wingfield and Michael P. Gilmore that we missed from last year. The topic is one that we have only briefly touched on a couple times. The wider world of honey and the bees responsible for it are topics we hope to share more of this year.

To begin, let this bring some joy:

A Sweet and Potent Harvest

For the Maijuna of the Peruvian Amazon, harvesting honey from stingless bees is bringing prosperity and empowerment. Local beekeeping might also help preserve a vast ancestral forest.When Tarkis Ríos Ushiñahua collects honey from one of her beehives, she wears no protective clothing and uses just one tool, a large plastic syringe. 1 As she lifts the lid from the wooden box housing the hive, the bees swarm. They buzz around her face, land on her back, and settle in strands of her straight black hair, but they do no harm — these bees are stingless.

If you have never seen ecosystem destruction firsthand, count yourself lucky. I witnessed, during visits over several years, as 1,000 acres of primary forest ecosystem was destroyed to make way for a rubber plantation. It was horrifying. And I am further horrified to read how what I witnessed was only a small part of a much bigger rubber-induced destruction (thanks as always to Fred Pearce):

How Mounting Demand for Rubber Is Driving Tropical Forest Loss

The growing market for rubber is a major, but largely overlooked, cause of tropical deforestation, new analysis shows. Most of the rubber goes to produce tires, more than 2 billion a year, and experts warn the transition to electric vehicles could accelerate rubber use.

The elephants are gone. The trees are logged out. The Beng Per Wildlife Sanctuary in central Cambodia is largely destroyed, after being handed over by the government to a politically well-connected local plantation company to grow rubber. 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 →

Nearly 12 years to the day since the first spectacular article we read on invasive species, we still watch for these stories. When it is invasive-hunting season, we take notice when new initiatives are announced:

Her Livelihood? Hunting Pythons in the Dead of Night.

Amy Siewe teaches people how to find and euthanize invasive Burmese pythons, which have been so successful at adapting to Florida that they appear here to stay.

An unexpected chill can fall over the Florida Everglades late at night. Stars speckle the sky. Frogs croak and croak, their mating calls echoing in the air.

It is all peace and wonder until you remember why you are out at this hour, on the flatbed of a pickup truck outfitted with spotlights, trying to find invasive creatures lurking in the shadows.

A python hunt might evoke images of hunters trudging through swamps and wresting reptiles out of the mud. In reality, it involves cruising the lonely roads that traverse the Everglades in S.U.V.s, hoping for a glimpse of a giant snake. It is strange work, straining on the eyes, brutal on the sleep schedule. Continue reading →
