Life as We Made It: How 50,000 Years of Human Innovation Refined--And Redefined--Nature
by Beth Shapiro
Published 15 Dec 2021

With each generation, the proportion of American chestnut DNA in each tree’s genome increased. Today, after three generations, these trees are 85 percent American chestnut and 15 percent Chinese chestnut. However, they also have reduced resistance to the fungal blight compared to trees with more Chinese chestnut DNA, which suggests that resistance is achieved by a suite of genes working in concert rather than just a single gene. While imperfect, these trees are helping American chestnuts make a comeback. Today, TACF supports forty restoration stands of hybrid trees across the former native range of the American chestnut. The American Chestnut Foundation’s hybrid trees are good but not great replicas of purebred American chestnuts.

Unfortunately, even these isolated stands are now threatened. The largest surviving stand—a nearly 100-year-old cluster of American chestnut trees near West Salem, Wisconsin—began showing signs of fungal infection in 1987. The American chestnut is, in a filling-its-ecological-niche sense, extinct. But the zombie shoots and expat trees provide what every de-extinction scientist desperately wants: living cells. Efforts to fill the vacant niche of the American chestnuts in eastern forests began in the 1920s. When imported fungus-resistant Chinese chestnuts failed to thrive in the American habitat, plant breeders tried to hybridize Chinese trees with surviving American trees—a standard approach in plant biotechnology.

Unfortunately, while the resulting hybrids did inherit resistance to the fungal disease, they fared poorly, presumably because such a large portion of their genomes had evolved elsewhere. In 1983, The American Chestnut Foundation was established, kicking off a decades-long quest to find a cure to chestnut blight. TACF was founded as a collaboration of conservation-minded laypeople and scientists, many from the State University of New York’s College of Environmental Science and Forestry. Their first project was to improve hybrid trees by increasing the amount of American chestnut DNA in their genomes. TACF scientists embarked on a thirty-plus-year backcrossing program in which they bred resistant hybrids with pure American chestnuts. With each generation, the proportion of American chestnut DNA in each tree’s genome increased.

Whole Earth Discipline: An Ecopragmatist Manifesto
by Stewart Brand
Published 15 Mar 2009

In Susan Freinkel’s lovely book on the subject, American Chestnut: The Life, Death, and Rebirth of a Perfect Tree (2007), the rebirth refers to efforts to genetically engineer a blight-resistant American chestnut. Two researchers made a derivative of a frog gene they thought would do the trick, but everyone told them they mustn’t put a frog gene in a plant that people eat. A forest biotech company named ArborGen approached the American Chestnut Foundation, offering to support research on a GE chestnut. They were turned away, of course. But research is going ahead anyway; I bet that an American chestnut 2.0 will be thriving by the 2020s and that Greens will welcome it by the end of that decade.

Mini Farming: Self-Sufficiency on 1/4 Acre
by Brett L. Markham
Published 14 Apr 2010

Chestnut blight was introduced into the United States before 1900 through the importation of various Asian chestnut species that carry the causative fungus but are resistant to it themselves. The American chestnut, native to Eastern North America, has no resistance to this fungus; within a generation this majestic tree, soaring up to 100 feet and measuring up to 10 feet across, was reduced to little more than a shrub that struggles a few years before succumbing to the threat. To put the impact of chestnut blight into perspective, it is estimated that in 1900, 25% of all the trees in the Appalachians were American chestnuts. There are four ways of dealing with chestnut blight: prompt removal of infected branches, treatment of cankers in existing trees for five years with injections of a hypovirulent strain of the fungus, planting resistant Asian chestnut varieties, and planting American varieties that have incorporated disease-resistant genes through repetitive backcrossing and selection to maximize native DNA content while retaining resistance genes.47 Mini-farmers interested in growing and preserving American chestnuts should seek guidance (and seeds!)

Farmers interested in resistant Asian stocks can find suitable varieties at local nurseries. Pecan scab, evidenced by sunken black spots on leaves, twigs, and nuts, is more of a problem in the southern than northern states.

Table 17 gives the ultimate distance that the trees should be from each other when fully grown. Table 17: Nut Tree Planting Distance Type of Nut Tree Distance between Trees Black walnut, hickory, pecan, and hican 50 feet in all direc tions English and Persian walnut 35 feet in all direc tions Chestnut (Chinese, most American chestnuts succumbed to the chestnut blight) 40 feet in all direc tions Filberts 15 feet in all direc tions Keep in mind that nut trees produce nuts long before reaching full size and that nut wood is some of the most expensive, so selling it could net a nice bundle. If you wish to do so, plant the nut trees about 10 feet apart and then selectively harvest them for wood as their branches come close to touching.

A Walk in the Woods: Rediscovering America on the Appalachian Trail
by Bill Bryson
Published 8 Sep 2010

The problem arises when a tree encounters an attacker for which evolution has left it unprepared, and seldom has a tree been more helpless against an invader than the American chestnut against Endothia parasitica. It enters a chestnut effortlessly, devours the cambium cells, and positions itself for attack on the next tree before the tree has the faintest idea, chemically speaking, what hit it. It spreads by means of spores, which are produced in the hundreds of millions in each canker. A single woodpecker can transfer a billion spores on one flight between trees. At the height of the American chestnut blight, every woodland breeze would lose spores in uncountable trillions to drift in a pretty, lethal haze on to neighboring hillsides.

Two-hundred-year-old pecan trees were commonly chopped down just to make it easier to harvest the nuts on their topmost branches. With each passing year the character of the woods changed perceptibly. But until quite recent times—painfully recent times—one thing remained in abundance that preserved the primeval super-Eden feel of the original forest: the massively graceful American chestnut. There has never been a tree like it. Rising a hundred feet from the forest floor, its soaring boughs spread out in a canopy of incomparable lushness, an acre of leaves per tree, a million or so in all. Though only half the height of the tallest eastern pines, the chestnut had a weight and mass and symmetry that put it in another league.

At the height of the American chestnut blight, every woodland breeze would lose spores in uncountable trillions to drift in a pretty, lethal haze on to neighboring hillsides. The mortality rate was 100 percent. In just over thirty-five years the American chestnut became a memory. The Appalachians alone lost four billion trees, a quarter of its cover, in a generation. A great tragedy, of course. But how lucky, when you think about it, that these diseases are at least species specific. Instead of a chestnut blight or Dutch elm disease or dogwood anthracnose, what if there was just a tree blight—something indiscriminate and unstoppable that swept through whole forests? In fact, there is. It’s called acid rain. But let’s stop there.

The Sixth Extinction: An Unnatural History
by Elizabeth Kolbert
Published 11 Feb 2014

When an entirely new pathogen shows up, it’s like bringing a gun to a knife fight. Never having encountered the fungus (or virus or bacterium) before, the new host has no defenses against it. Such “novel interactions,” as they’re called, can be spectacularly deadly. In the eighteen hundreds, the American chestnut was the dominant deciduous tree in eastern forests; in places like Connecticut, it made up close to half the standing timber. (The tree, which can resprout from the roots, did fine even when heavily logged; “not only was baby’s crib likely made of chestnut,” a plant pathologist named George Hepting once wrote, “but chances were, so was the old man’s coffin.”)

The End of Doom: Environmental Renewal in the Twenty-First Century
by Ronald Bailey
Published 20 Jul 2015

Biotechnology could also restore the majestic American chestnut to its home in the forests of the eastern United States. In the early twentieth century, chestnut blight fungus introduced from overseas devastated American chestnuts—the then-dominant trees in eastern forests stretching from Maine to Mississippi. Researchers at the State University of New York College of Environmental Science and Forestry (SUNY), working with the American Chestnut Research and Restoration Project, used genetic engineering techniques to introduce a gene from wheat that confers strong blight resistance into American chestnut trees. They recently ceremonially planted some of the new blight-resistant chestnuts at the New York Botanical Garden in the Bronx, where the blight was first identified.

Under a White Sky: The Nature of the Future
by Elizabeth Kolbert
Published 15 Mar 2021

Brand has co-founded a group, Revive & Restore, whose stated mission is to “enhance biodiversity through new techniques of genetic rescue.” Among the more fantastic projects the group has backed is an effort to resurrect the passenger pigeon. The idea is to reverse history by rejiggering the genes of the bird’s closest living relative, the band-tailed pigeon. Much closer to realization is an effort to bring back the American chestnut tree. The tree, once common in the eastern United States, was all but wiped out by chestnut blight. (The blight, a fungal pathogen introduced in the early twentieth century, killed off nearly every chestnut in North America—an estimated four billion trees.) Researchers at the SUNY College of Environmental Science and Forestry, in Syracuse, New York, have created a genetically modified chestnut that’s immune to blight.

As Tizard points out, we’re constantly moving genes around the world, usually in the form of entire genomes. This is how chestnut blight arrived in North America in the first place; it was carried in on Asian chestnut trees, imported from Japan. If we can correct for our earlier tragic mistake by shifting just one more gene around, don’t we owe it to the American chestnut to do so? The ability to “rewrite the very molecules of life” places us, it could be argued, under an obligation. Of course, the argument against such intervention is also compelling. The reasoning behind “genetic rescue” is the sort responsible for many a world-altering screwup. (See, for example, Asian carp and cane toads.)

Nomad Century: How Climate Migration Will Reshape Our World
by Gaia Vince
Published 22 Aug 2022

Grass verges lining roads and in cities could be diversified and left unmown – again, in the UK, the cumulative verge area is equivalent in size to the county of Dorset. Given the scale and extent of biodiversity loss, interventions are now essential in many cases to enable species to cope with human changes to the environment. We have genetic tools to help species adapt to Anthropocene conditions, although it’s a time-consuming and expensive process. American chestnut trees in the US have been genetically altered to protect the species from blight; black-footed ferrets are being cloned to bring the species back from the brink; and coral colonies are being genetically engineered to withstand hotter seas. In some cases, species in danger will need to be helped to migrate through active translocation; in others, special protective zones and policies will be needed – in Rwanda, for instance, tourists pay a premium to visit gorillas and this money pays for community development projects as well as wildlife protection.

Animals bred in captivity can be vaccinated before release, but as proposed by Ryan Phelan and colleagues at the nonprofit Revive & Restore, CRISPR editing offers a means to transfer plague resistance from the domestic ferret to its black-footed cousin.19 Meanwhile, similar strategies are needed to save some other iconic American plants and wildlife. The American chestnut tree population has been ravaged by chestnut blight, a disease spread by a Japanese fungus that was first observed in the Bronx Zoo. William Powell’s team has engineered a hybrid genetically modified tree that contains a wheat gene that neutralizes the acid produced by the fungus. Powell is petitioning the US government to produce a transgenic forest species,20 despite opposition from environmentalists who worry about GM trees.

Land: How the Hunger for Ownership Shaped the Modern World
by Simon Winchester
Published 19 Jan 2021

My own land nowadays has stands of eastern hemlock and pignut hickory, tulip poplar and white pine, beech and birch, conifers and ash, cherry and witch hazel and two kinds of maple, one with sap to be boiled for sugaring, the other tiger-striped and used today in the making of furniture. Apple trees can be found once in a while, though none on my property, so far as I know. No doubt all these trees would have been there in Henry Hudson’s time, and some for long before. There used to be American chestnut trees—a blight has ravaged them in recent years—and it was customary to plant them as corner markers to define the edges of a plot of land. Chestnut was once the dominant wood for building barns and houses, but not since the trees were forced into near extinction. The soil is too thin to support massive species—no great oaks or elms, no trees tall enough and straight enough for repairing or replacing the masts of big sailing ships—so often a motive for a ship’s master arriving in a foreign land after long sea crossing.

Grand Transitions: How the Modern World Was Made

Cane toads, large South American poisonous amphibians introduced to Queensland in 1935 in order to control cane beetles, have been expanding their range by up to 60 km/year and by 2009 they crossed the border of Western Australia and Northern Territory, more than 2,000 km from the site of their original release (DPW 2014). Chestnut blight fungus (Cryphonectria parasitica), introduced at the beginning of the 20th century, destroyed the American chestnut, a large and dominant tree of Eastern American forests (Freinkel 2007). Asian ascomycete fungus (Ophiostoma) arrived in the eastern United States first in 1928 via Europe, and it has destroyed most of American elms (Ulmus americana) as far west as Saskatchewan (Hubbes 1999). And the third Asian invader is woolly adelgid, a small sap-sucking insect (Adelges tsugae) now destroying North American hemlocks, Tsuga canadensis and Tsuga caroliniana (Nuckolls et al. 2009).

Woolly: The True Story of the Quest to Revive History's Most Iconic Extinct Creature
by Ben Mezrich
Published 3 Jul 2017

Many wild populations of animals and plants are profoundly threatened by exotic diseases—chytrid fungus in frogs, sylvatic plague in black-footed ferrets, Rapid Ohi’a Death in the keystone ohi’a trees of Hawaii, avian malaria in the forest birds of Hawaii. Can disease resistance be engineered into the genomes of those species? It has been done successfully for the legendary American chestnut tree, once driven to functional extinction by the blight that killed 4 billion trees in the early twentieth century. Scientists at SUNY in New York made the trees blight-proof by introducing a fungus-resistant gene from wheat, and the improved tree is now going through the approval process with government regulators.

1491

Sometime in the first millennium A.D., the Indians who had burned undergrowth to facilitate grazing began systematically replanting large belts of woodland, transforming them into orchards for fruit and mast (the general name for hickory nuts, beechnuts, acorns, butternuts, hazelnuts, pecans, walnuts, and chestnuts). Chestnut was especially popular—not the imported European chestnut roasted on Manhattan street corners in the fall, but the smaller, soft-shelled, deeply sweet native American chestnut, now almost extinguished by chestnut blight. In colonial times, as many as one out of every four trees in between southeastern Canada and Georgia was a chestnut—partly the result, it would seem, of Indian burning and planting. Hickory was another favorite. Rambling through the Southeast in the 1770s, the naturalist William Bartram observed Creek families storing a hundred bushels of hickory nuts at a time.

For many groups in the Southeast, milk from mast was the only kind of milk available. Lack of evidence for deaths or hunger: Milner 1992. Palisade: Iseminger 1990. In a novel interpretation, Pauketat argues that the Cahokians’ attempt to shut themselves behind a palisade actually could have been “an offensive tactic” that let Cahokia’s rulers “project a larger-than-normal armed force by freeing up people who otherwise would have guarded the capital” (Pauketat 1998:71).

Green Metropolis: Why Living Smaller, Living Closer, and Driving Less Are Thekeys to Sustainability
by David Owen
Published 16 Sep 2009

A couple of months after she learned to walk, we moved to a small town in the northwest corner of Connecticut, about ninety miles north of midtown Manhattan. Our house was built in the late 1700s. During a rainstorm one night soon after we moved in, I stuck my head into the attic and ran a flashlight over the underside of the roof. The decking boards had been made, two hundred years before, from the broad trunks of old-growth American chestnut trees, a species that was wiped out by an imported blight in the first half of the twentieth century, and some of them were almost as broad as sheets of plywood. The rafters, which were hand-hewn, were joined not by iron nails but by wooden pegs. Carved near the ends of some of the rafters were large Roman numerals, which had been placed there as assembly aids by the anonymous eighteenth-century builder.

The Hot Zone

One day, she had finally said to Jerry, “You can sit in the driveway in those red leather seats all you want, but I’m not getting in there with you.” So they sold the Cadillac and bought a Honda Accord. The Jaaxes’ house was the largest Victorian house in town, a pile of turreted brick with a slate roof and tall windows and a cupola and wooden paneling made of golden American chestnut. It stood on a street corner near the ambulance station. The sirens woke them up at night. They had bought the house cheap. It had sat on the market a long time, and a story had been going around town that the previous owner had hanged himself in the basement. After the Jaaxes bought it, the dead man’s widow showed up at the door one day.

The World Without Us

Published 5 Aug 2008

As plants die, decay, and lay down more soil cover, the industrial toxins will be buried deeper, and each succeeding crop of native seedlings will do better. And although many of New York’s heirloom trees are endangered if not actually dying, few if any are already extinct. Even the deeply mourned American chestnut, devastated everywhere after a fungal blight entered New York around 1900 in a shipment of Asian nursery plants, still hangs on in the New York Botanical Garden’s old forest—literally by its roots. It sprouts, sends up skinny shoots two feet high, gets knocked back by blight, and does it again.

Alistair Cooke's America
by Alistair Cooke
Published 1 Oct 2008

And traveling past the rickety cabins of the black man’s back country, and through his scabrous city slums, there often seemed to be only one American theme song: ‘Sometimes I’m up, Sometimes I’m down, And sometimes I’m almost to the ground.’ More often than I care to admit, one of the oldest of American chestnuts seemed newly roasted. It is that line of the Italian immigrant asked to say what forty years of American life had taught him: ‘There is no free lunch.’ By now it is a facetious truism, but it is also a profound truth forgotten by the Founding Fathers in the ecstasy of promising everybody life, liberty, and the pursuit of happiness – and it is forgotten again today when committees of Congress imply that transferring $40,000,000 of tax money from the defense budget to revenue sharing will fix everything.

The Next Great Migration: The Beauty and Terror of Life on the Move
by Sonia Shah

As the creatures he once studied became the subject of extermination campaigns, his assessment of the threat posed by animals on the move took on a new tenor. Everywhere he looked, he saw wild creatures migrating into new places, and precipitating disaster. In the United States, he noted, the arrival of Asian chestnut trees24 had introduced a parasitic fungus called Endothia parasitica, causing “chestnut blight,” which nearly wiped out eastern American chestnut trees. In Europe, a landowner in Czechoslovakia had introduced five North American muskrats. They grew into a population of millions, rampaging through croplands and burrowing into the banks of rivers and streams. In the midwestern United States, the construction of canals introduced the blood-sucking sea lamprey into the Great Lakes.

The Rise and Fall of the Third Chimpanzee
by Jared Diamond
Published 2 Jan 1991

Europe too has acquired introduced species, of which the misnamed Norway rat is an example (it originated in Asia, not Norway). When species are introduced from one region to another, they often proceed to exterminate some of the new species they encounter, by eating them or causing diseases. The victims evolved in the absence of the introduced Pests and never developed defences against them. American chestnut trees have already been virtually exterminated in this way by chestnut b"ght, an Asian fungus to which Asian chestnut trees are resistant. milarly, goats and rats have exterminated many plants and birds on oceanic islands. Have we already spread all possible pests all around the world? Obviously not; there are many islands still free of goats and Norway rats, and many insects and diseases to try to keep out of many countries by quarantines.

The Gun

Shortly after World War II, the army contracted with private researchers, detached from its customs and bureaucracy, who made pointed recommendations for new training and equipment. The group, called the Operations Research Office, combed classified data and literature in offices at Johns Hopkins University and secretly reached conclusions that challenged two preeminent American chestnuts: the value of the long-range rifle and the belief in the shooting skills of marksmen. Available data showed that whatever the abilities of soldiers on rifle ranges, under the stress and visibility conditions of actual war, the preponderance of combat shooting was more pedestrian than legend suggested.

There are by now literally hundreds of cases in which alien species have caused one-time or annually recurring damages of hundreds of millions of dollars or even billions of dollars. Modern examples include Australia's rabbits and foxes, agricultural weeds like Spotted Knapweed and Leafy Spurge (Chapter 1), pests and pathogens of trees and crops and livestock (like the blights that wiped out American chestnut trees and devasted American elms), the water hyacinth that chokes waterways, the zebra mussels that choke power plants, and the lampreys that devastated the former commercial fisheries of the North American Great Lakes (Plates 30, 31). Ancient examples include the introduced rats that contributed to the extinction of Easter Island's palm tree by gnawing its nuts, and that ate the eggs and chicks of nesting birds on Easter, Henderson, and all other Pacific islands previously without rats. 10.

Growth: From Microorganisms to Megacities

The cyclone of 1938 downed about 70% of all timber in Harvard Forest in central Massachusetts (Spurr 1956). Regrowth has largely healed those losses (Weishampel et al. 2007), but one of the region’s dominant trees is now on the verge of extinction. Before 2030, the eastern hemlock (Tsuga canadensis) might join the American chestnut as yet another species that has succumbed to a pest, in this case to the woolly adelgid (Adelges tsugae), a small aphid-like insect from East Asia that has been killing hemlock trees since the 1960s with no known defense against its depredations (Foster 2014). Reforestation has been particularly impressive in Europe.
