We knew from a recent post about the importance of small tracts of tree cover, based on reporting in the USA. Here is more from Europe, and about the botanist inspiring an acceleration of planting:

Fast-growing mini-forests spring up in Europe to aid climate

Miyawaki forests are denser and said to be more biodiverse than other kinds of woods

Tiny, dense forests are springing up around Europe as part of a movement aimed at restoring biodiversity and fighting the climate crisis.

Often sited in schoolyards or alongside roads, the forests can be as small as a tennis court. They are based on the work of the Japanese botanist Akira Miyawaki, who has planted more than 1,000 such forests in Japan, Malaysia and elsewhere. Continue reading →

Gabriel Popkin takes a “who knew?” topic and brightens up the day:

How Small Family Forests Can Help Meet the Climate Challenge

As efforts grow to store more CO2 emissions in forests, one sector has been overlooked — small, family-owned woodlands, which comprise 38 percent of U.S. forests. Now, a major conservation initiative is aiming to help these owners manage their lands for maximum carbon storage.

Tim Leiby had wrapped up a fun but fruitless early-morning turkey hunt and was enjoying an old John Wayne flick when I arrived at Willow Lodge near Blain, Pennsylvania. A few flurries drifted down on this unseasonably cold May morning. After a quick scan of antlers mounted on virtually every wall of the cozy hunting lodge, we headed out for a socially distanced stroll through what Leiby calls “our little piece of heaven.”

This 95-acre woods in south-central Pennsylvania’s ridge-and-valley country is a hunting and hiking refuge co-owned by eight families. Continue reading →

Tamara and Steve Davey cannot help but grin at the suggestion they are “miniature rewilders”. Standing proudly in the weak sunlight on the fringes of Dartmoor national park, the full-time grandmother and taxi company owner delight in their eight-acre woodland.

Robins, tits and siskins chortle in the trees. Nightjars are welcome visitors in the summer. Seven bat species have been recorded in their small plot. There’s a badger’s sett somewhere in the hillside scrub. And the couple feel at peace.

A seasonal distraction, more than welcome, and we thank Cool Green Science for featuring Ken Keffer’s primer on North American tree-tapping:

Tree Tapping Isn’t Just for Maples

March is tree tapping season across the upper Midwest, New England, and southern Canada. As the cardinals start to sing again in the northwoods, the long-dormant timbers are also responding to the first signs of early spring.

Sap is stored in the roots over winter, but as temperatures begin to rise, it starts flowing through the xylem layer of the tree.

For a number of species, the sap flow becomes a sweet treat and a renewable resource for those working the sugarbush.

Tapping Throughout History

The exact origins of making maple syrup are a bit of a mystery. It is clear that a number of indigenous tribes in northeastern North America were utilizing this natural resource, and the process predates European settlers. Continue reading →

Thanks to Ian Morse for the most surprising twist on the mythological possibilities of the philosopher’s stone:

Down on the Farm That Harvests Metal From Plants

Hyper-accumulating plants thrive in metallic soil that kills other vegetation, and botanists are testing the potential of phytomining.

Some of Earth’s plants have fallen in love with metal. With roots that act practically like magnets, these organisms — about 700 are known — flourish in metal-rich soils that make hundreds of thousands of other plant species flee or die.

Slicing open one of these trees or running the leaves of its bush cousin through a peanut press produces a sap that oozes a neon blue-green. This “juice” is actually one-quarter nickel, far more concentrated than the ore feeding the world’s nickel smelters. Continue reading →

The Trees That May Survive Humanity

Alex Ross mainly writes about music, but when he sets his sights on other important topics his musicality illuminates in a powerful way:

The Past and the Future of the Earth’s Oldest Trees

Bristlecone pines have survived various catastrophes over the millennia, and they may survive humanity.

About forty-five hundred years ago, not long after the completion of the Great Pyramid at Giza, a seed of Pinus longaeva, the Great Basin bristlecone pine, landed on a steep slope in what are now known as the White Mountains, in eastern California. The seed may have travelled there on a gust of wind, its flight aided by a winglike attachment to the nut. Or it could have been planted by a bird known as the Clark’s nutcracker, which likes to hide pine seeds in caches; nutcrackers have phenomenal spatial memory and can recall thousands of such caches. This seed, however, lay undisturbed. On a moist day in fall, or in the wake of melting snows in spring, a seedling appeared above ground—a stubby one-inch stem with a tuft of bright-green shoots.

Most seedlings die within a year; the mortality rate is more than ninety-nine per cent. The survivors are sometimes seen growing in the shadow of a fallen tree. Continue reading →

These are times that test our patience. Obvious, right? So is the subject of this essay. And yet, it bears saying, and repeating, precisely because of the times we find ourselves in. So thanks to Mr. Heacox for saying so and to Yale e360 for publishing it:

Let It Be: Why We Must Save Alaska’s Pristine Tongass Forest

At 17 million acres, Alaska’s Tongass is the largest U.S. national forest and the world’s largest remaining temperate rainforest. Now, the Trump administration wants to resume large-scale logging in the Tongass, one of several initiatives threatening some of Alaska’s wildest lands.

When the railroad tycoon Edward H. Harriman fell ill from stress and too much work, his doctors recommended that he take a sea cruise. Unable to do anything in a small way, Harriman filled a ship with America’s foremost scientists, artists, and writers, and sailed the coast of Alaska for two months in the summer of 1899.

The expedition, which also included the renowned preservationists John Muir and George Bird Grinnell, found two Alaskas wherever they went, one for the taking, one for the saving. Each at odds with the other. Foremost among the places for saving was the great coastal rainforest of the Southeast Alaska panhandle, a wondrous world of mountains, ice fields, tidewater glaciers, rock-ribbed fjords, coastal brown bears, bald eagles, and 11,000 miles of shoreline.

Eight years later, in 1907, President Theodore Roosevelt took a bold step in that direction by creating the 17-million-acre Tongass National Forest, the largest national forest in the United States. Today, the Tongass contains two national monuments and 19 designated wilderness areas. It also has countless undammed rivers and streams, and some of the world’s last great runs of wild Pacific salmon. Continue reading →

Proforestation & The Value Of Mature Forests

Thanks to Yale e360 for this interview that helps us understand the dynamics and differences between mature forests and newly planted forests in terms of carbon sequestration:

Why Keeping Mature Forests Intact Is Key to the Climate Fight

Preserving mature forests can play a vital role in removing CO2 from the atmosphere, says policy scientist William Moomaw. In an e360 interview, he talks about the importance of existing forests and why the push to cut them for fuel to generate electricity is misguided.

William Moomaw has had a distinguished career as a physical chemist and environmental scientist, helping found the Center for International Environment and Resource Policy at Tufts University’s Fletcher School and serving as lead author on five reports of the Intergovernmental Panel on Climate Change (IPCC). In recent years, Moomaw has turned his attention to working on natural solutions to climate change and has become a leading proponent of what he calls “proforestation” — leaving older and middle-aged forests intact because of their superior carbon-sequestration abilities.

While Moomaw lauds intensifying efforts to plant billions of young trees, he says that preserving existing mature forests will have an even more profound effect on slowing global warming in the coming decades, since immature trees sequester far less CO2 than older ones. In an interview with Yale Environment 360, Moomaw explains the benefits of proforestation, discusses the policy changes that would lead to the preservation of existing forests, and sharply criticizes the recent trend of converting forests in the Southeastern U.S. to wood pellets that can be burned to produce electricity in Europe and elsewhere.

“The most effective thing that we can do is to allow trees that are already planted, that are already growing, to continue growing to reach their full ecological potential, to store carbon, and develop a forest that has its full complement of environmental services,” said Moomaw. “Cutting trees to burn them is not a way to get there.”

Yale Environment 360: How do you define proforestation?

William Moomaw: So I began looking at some of the data and some of the papers that had come out recently, and I found that if we managed our forests and grasslands in a different way they could be sequestering twice as much carbon dioxide from the atmosphere as they currently do.

Organikos, 100% Forward To 1,000,000

/ Crist Inman / Leave a comment

6555On July 5th I first read the news about what planting a trillion trees might do for the fight against climate change. One week later this magazine cover drove the point further home for me with the Woody Guthrie reference. Organikos already had ideas and imagery for the commitment of 100% of its profits to conservation, and by the time I saw this cover I knew our focus would be on planting trees. Coming back to this magazine cover now, I am struck by the power of the number referenced in the scientific study.

One trillion.

1,000,000,000,000.

How long would it take Organikos to plant one million of those trees?

Camera traps have proven valuable in the work we have been doing in Belize, India and elsewhere in the wilderness areas of the developing world. But equally important are the photos captured in areas closer to urban settlements. Thanks to The Nature Conservancy’s publication of these photos with the article below:

As a Nature Conservancy forester in Pennsylvania, Mike Eckley spends a lot of time assessing the health of woodlands. That means he spends as much time thinking about white-tailed deer as he does trees.

Many conservation biologists consider over-abundant deer to be an even bigger threat to eastern forests than climate change. Deer can fundamentally change the forest ecosystem, threatening everything from rare wildflowers to migratory songbirds. These deer also can cause deadly vehicle collisions, increase risk of Lyme disease, and cause significant agricultural and property damage.

Eckley educates hunting clubs and landowners on deer management issues, and recently co-edited a book on the topic.

20SCI-EARTHWORM1-jumbo.jpg

The world’s boreal forests have been largely earthworm-free since the last Ice Age. But as invaders arrive and burrow into the leaf litter, they free up carbon and may accelerate climate change. Cristina Gonzalez Sevilleja

In my daily scan for information related to the environment, I invariably learn something that surprises me. Like the fact that the earthworm, which provide valuable ecosystem services, can also represent danger on a global scale:

‘Earthworm Dilemma’ Has Climate Scientists Racing to Keep Up

Worms are wriggling into Earth’s northernmost forests, creating major unknowns for climate-change models.

Cindy Shaw, a carbon-research scientist with the Canadian Forest Service, studies the boreal forest — the world’s most northerly forest, which circles the top of the globe like a ring of hair around a balding head.

A few years ago, while conducting a study in northern Alberta to see how the forest floor was recovering after oil and gas activity, she saw something she had never seen there before: earthworms.

“I was amazed,” she said. “At the very first plot, there was a lot of evidence of earthworm activity.”

Native earthworms disappeared from most of northern North America 10,000 years ago, during the ice age. Now invasive earthworm species from southern Europe — survivors of that frozen epoch, and introduced to this continent by European settlers centuries ago — are making their way through northern forests, their spread hastened by roads, timber and petroleum activity, tire treads, boats, anglers and even gardeners.

TUCSON — From the early 1700s until the 1960s, the fast moving river of wind known as the North Atlantic Jet Stream, which drives weather extremes over Europe, was pretty steady on its course.

Then it became less predictable. But instrument data alone can’t tell the jet stream’s movements for comparison over the centuries, given that scientists began keeping records of weather events via instruments only in the late 19th century. Continue reading →

A Game of Arboreal Chess Against Climate Change

/ Organikos / Leave a comment

Illustrations by Andrew Khosravani

Those familiar with this site know that climate change denial would find difficult footing; no leap of faith is required to take it as scientific fact. We appreciate the following examples of learning from recent history of forest collapse and planning for environmental changes accordingly.

Can Humans Help Trees Outrun Climate Change?

SCITUATE, R. I. — Foresters began noticing the patches of dying pines and denuded oaks, and grew concerned. Warmer winters and drier summers had sent invasive insects and diseases marching northward, killing the trees.

If the dieback continued, some woodlands could become shrub land.

Most trees can migrate only as fast as their seeds disperse — and if current warming trends hold, the climate this century will change 10 times faster than many tree species can move, according to one estimate. Rhode Island is already seeing more heat and drought, shifting precipitation and the intensification of plagues such as the red pine scale, a nearly invisible insect carried by wind that can kill a tree in just a few years.

The dark synergy of extreme weather and emboldened pests could imperil vast stretches of woodland.

So foresters in Rhode Island and elsewhere have launched ambitious experiments to test how people can help forests adapt, something that might take decades to occur naturally. One controversial idea, known as assisted migration, involves deliberately moving trees northward. But trees can live centuries, and environments are changing so fast in some places that species planted today may be ill-suited to conditions in 50 years, let alone 100. No one knows the best way to make forests more resilient to climatic upheaval.

These great uncertainties can prompt “analysis paralysis,” said Maria Janowiak, deputy director of the Forest Service’s Northern Institute of Applied Climate Science, or N.I.A.C.S. But, she added, “We can’t keep waiting until we know everything.” Continue reading →

Fred Pearce provides puzzling yet somehow understandable examinations of environmental challenges, that make it impossible to look away with a clear conscience. Since reading this (note the photo above and in that story) I have been paying more attention to chocolate and its origins. I appreciate Mr. Pearce’s deep dive into the dark reality documented in this story:

The Real Price of a Chocolate Bar: West Africa’s Rainforests

Ivory Coast has lost more than 80 percent of its forests in the last 50 years, mainly to cocoa production. The government has a plan to turn over management of former forest to international chocolate manufacturers: Is it a conservation strategy or a land grab?

How can you save the last rainforests from rampant deforestation in one of Africa’s most biodiverse countries? A crackdown on those responsible — in this case, chocolate growers and traders? In the Ivory Coast, the government thinks differently. It is unveiling a plan instead to remove protection from most of its remaining forests and hand them over to the world’s chocolate traders. Is this madness, a brutal land grab, or the only way out?

A park ranger stands over illegally harvested cocoa, found during a routine patrol of the Cavally Classified Forest in Ivory Coast. MIGHTY EARTH

In the past half-century, few countries have lost rainforests as fast as the Ivory Coast. More than 80 percent of its forests are gone, most following an illegal invasion by as many as a million landless people into national parks and other supposedly protected forests. The Marahoue National Park alone has 30,000 illegal inhabitants. The invaders are growing cocoa to supply the global chocolate business.

The Ivory Coast, a West African country the size of New Mexico, produces more than a third of the world’s cocoa. The crop contributes around a tenth of the nation’s GDP. But around 40 percent of the country’s cocoa crop — more than a tenth of the world’s chocolate bars — is grown illegally in the country’s national parks and 230 supposedly protected government-owned forests, known as forêts classée, says Etelle Higonnet of Mighty Earth, a United States-based environmental group active in cataloging the footprint of key global commodities.

Most cocoa is grown in monocultures of what is known as the full-sun system, requiring the removal of all surrounding trees. Meeting the world’s insatiable demand for the beans that make chocolate has resulted in many protected areas being “completely converted to farms,” according to Eloi Anderson Bitty of the University Felix Houphouet-Boigny in Abidjan.

In India’s Fast-Growing Cities, a Grassroots Effort to Save the Trees

In India’s burgeoning urban areas, residents are rallying against the widespread destruction of trees to make way for development. The recent protests highlight a global issue: densely populated megacities in the developing world, which are most in need of tree cover, often have the least.

The funeral cortege was small. Six people shouldered the bier and others followed, clad in the traditional Indian white. As the group filed past the state assembly building, the armed guards did not give it a second glance. In a few minutes, however, the security forces caught on. The procession winding its way through Mumbai’s government district was not a real funeral: It was a protest. The shrouded body held aloft was not a human — it was the trunk of a tree, one of many, including grand old banyans, cut down for the construction of a $3.3 billion subway line.

Mumbai’s old trees have borne the brunt of new development in the booming city, including road widening, transport projects, and housing construction. The new subway alone is destroying or damaging 5,000 trees, from hundreds of old street trees in the dense parts of the historic island city to more than 2,000 trees in a mini-forest in suburban Aarey Colony, where a rail car shed is to be built. A less visible loss lies in defunct industrial areas, where large plots with old trees and ponds are being redeveloped into residential and commercial towers. “Developers are supposed to replace the trees but no one really checks,” says Stalin D., head of local environmental group, Vanashakti.

If you have been following the news recently, you may have noticed a report that indicates the urgency from climate change is greater than scientists previously thought. Everyone who cares has been digesting the science and we appreciate every effort to clarify what the science is saying. Fred Pearce, writing for Yale e360, has this:

Conflicting Data: How Fast Is the World Losing its Forests?

The latest UN report on climate says reducing deforestation is crucial to slowing global warming. But researchers must first reconcile two contradictory sets of statistics on tree loss in order to determine whether promises made by nations to protect and restore forests are on target.

The world is losing trees faster than ever. An area the size of Italy disappeared last year. Or did it? New research suggests three-quarters of those lost forests may already be regrowing. That hardly means we are out of the woods. Fighting climate change and protecting biodiversity still needs a global campaign to reforest the planet. But it does suggest that, given the chance, nature will do much of the work. Continue reading →

Our practice was born in Costa Rica, so we sometimes may appear partisan when it comes to celebrating the sciences related to biodiversity. Costa Rica has impressive credentials in that realm, especially relative to its size as a country. But we are very clear on the fact that it would take dozens of Costa Rica-sized biodiversity hotspots to match the scale of the Amazon region, and it is no surprise that studies like those of these scholars are carried out with Amazonian data:

The Amazon as engine of diverse life

“Most evolutionary research focuses on how new species form. But we want to understand how whole ecosystems evolve,” said Alexandre Antonelli.
 Rose Lincoln/Harvard Staff Photographer

A recent study says that many of the plants and animals that call Latin America home may have had their roots in the Amazon region.

The study, co-authored by Harvard Visiting Scholar Alexandre Antonelli and an international team of researchers, says that a dynamic process of colonization and speciation led to the formation of the American tropics, which is the most species-rich region on the planet. The study is described in a paper published in the Proceedings of the National Academy of Sciences.

“We were astonished to detect so much movement across such different environments and over such large distances,” said Antonelli, the study’s lead author. “Up until now, these natural dispersal events were assumed to be quite rare. Our results show how crucial these events have been in the formation of tropical America’s unique and outstandingly rich biodiversity.” Continue reading →
