Leveretts prepared acceptance by this community of tree-lovers, numerous of them beginners, wasnt necessarily reflected in the expert forestry neighborhood, which can feel like a tangle of competing interests, from forest managers to ecology PhDs. In the early 1990s, he wrote a series of short articles for the quarterly journal Wild Earth to assist spread his ideas about old development among the grassroots environmentalist neighborhood (it was Wild Earth co-founder John Davis who initially dubbed Leverett the old-growth evangelist). In 1993, Leverett co-founded the Ancient Eastern Forest conference series, which brought forest professionals together with ecologists from some of the most prominent scholastic departments in the nation.
Discovering old-growth trees remarkable capacity to sequester carbon, Leverett developed an approach for approximating a trees height within five inches.

As Leverett recalls it, one of his most significant insights came on a summer season day in 1990 or 1991. Leverett had seen enough big sugar maples in his life to know that this was absolutely not the case.

We are standing over the fallen remains of that very exact same sugar maple on a drizzly fall day some 30 years later.– the top wasnt over the base … I was off by about 30 feet.”.

” A lot of people were skeptical: Even forest ecologists at universities had simply given up on the idea that there was any old development in Massachusetts,” states Lee Frelich, director of the University of Minnesota Center for Forest Ecology and a long time good friend of Leveretts. “They just didnt know how to recognize certain kinds of old growth– nobody in New England might see it.”.
A rarity in western Massachusetts and elsewhere: 2 root systems support trunks that merge into one.
In all our discussions, Leverett is reticent about the degree of his impact. What he appears most thinking about is how the forest impacts individual people. “Theres a spiritual quality to being out here: You walk quietly through these woods, and theres a spirit that comes out. My first wife said, You understand, Bob, youre expected to bring individuals to the forest, youre expected to open the door for them. Theyll learn thereafter.”.
To get in a forest with Bob Leverett is to send to a convivial narration of the natural world, defined as much by its tangents as its destinations– by its opportunities for seeing. At 80, Leverett stays active, powered by an apparently endless enthusiasm for sharing his experience of the woods with newbies like me. Born and raised in mountain towns in the Southern Appalachians, in a house straddling the state line between Georgia and Tennessee, Leverett served for 12 years as an Air Force engineer, with stints in the Dakotas, Taiwan and the Pentagon, but he hasnt lost any of his pleasant Appalachian twang. And though hes lived the bulk of his life in New England, where he worked as an engineering head of a management consulting firm and software designer up until he retired in 2007, he comes across like something between an old Southern senator and an itinerant preacher, prepared to filibuster or sermonize at a minutes notification. Inevitably, the topic of these sermons is the importance of old-growth forest, not only for its serene impact on the human soul or for its biodiversity, however for its vital role in mitigating environment change.

Forests.
If the objective is to minimize global warming, climate scientists often stress the value of afforestation, or planting new forests, and reforestation, or regrowing forests. However there is a 3rd approach to handling existing forests: proforestation, a term created by climate scientist William Moomaw to describe the conservation of older existing forests. (Moomaw was a lead author of five significant reports of the Intergovernmental Panel on Climate Change, which was awarded the Nobel Peace Prize in 2007.) All of these strategies have a function to play. What Leverett has actually helped reveal in the last few years is how much more valuable proforestation is than we first believed. He has provided hard information that older trees build up even more carbon later on in their life process than lots of had recognized: In studying specific Eastern white pines over the age of 150, Bob had the ability to determine that they collect 75 percent of their overall carbon after 50 years of age– a pretty crucial finding when every year counts in our struggle to alleviate the impacts of climate modification. Merely planting new forests wont do it..
And this is when Leverett and Sobon recognized something critical: Measuring for height, no one, obviously– not lumberjacks, not foresters, not ecologists– had been permitting for the plain truth that trees grow crooked. Back then, Leverett explains, the standard method to field-measure a tree was quite basic, and had been used for decades: “You extend a tape out, level with your eye, to the trunk of the tree, then take an angle to the leading and an angle to the bottom. Leverett would find over the subsequent years that this same method had led to widespread mismeasurement of many tree types.

One of those calls was from Tad Zebryk, a Harvard researcher who asked Leverett if he could tag along to look at some of these trees. Leverett invited Zebryk for a hike near the New York-Massachusetts border, not far from the town of Sheffield, Massachusetts. “I was pretty comfortable that it was old growth– its around a waterfall, rather inaccessible to what would have been initial lumbering operations,” Leverett recalls.

Ecology.
The turning point in Leveretts nascent ministration was when he went public with his observations in the Spring 1988 edition of the publication the Woodland Steward, with an article about discovering old-growth forest in Massachusetts Deerfield River Gorges. The reaction among forest ecologists was unforeseen, a minimum of to Leverett. “By Jove, my telephone started ringing off the hook. Individuals I d never ever thought of learning more about called and stated, Are you really discovering old growth in the Berkshires?”.

Leveretts evangelism has actually had a concrete effect on the preservation of old development in his adopted home state of Massachusetts. As a popular figure in a loose coalition of groups– the Massachusetts Forest Trust, the Native Tree Society, the Forest Stewards Guild, Friends of Mohawk Trail State Forest– devoted to the identification and preservation of old-growth forest, Leveretts work has actually triggered the commonwealth to add 1,200 acres of old development to its forest reserves. At the heart of Leveretts quest lies an easy message that continues to appeal to the scientist and spiritualist alike: We have a responsibility to safeguard old-growth forest, for both its beauty and its significance to the world.
Ever the engineer, Leverett had actually also begun taking meticulous measurements of the height and circumference of old trees, and simply a couple of years after the Woodland Steward post, he pertained to another stunning awareness: The height of American tree species, for generations, had actually been commonly mismeasured by loggers and academics alike. This deep attention to information– Bobs remarkable capacity for observing basic facts about the forest that others had neglected– would fundamentally change our understanding of old forests, including their capacity for mitigating the results of environment change.
One benefit of old-growth forests is the variety of organisms they support, whether animal, microorganism– or fungus.
Considering that then, Leverett has led countless individuals on trips of old-growth forest under the aegis of groups like the Massachusetts Audubon Society, the Sierra Club and the Hitchcock Center for the Environment, and released scores of short articles and essays, from philosophical meditations on the spiritual significance of old-growth forest, to more academic work. Leverett is also set to lead a workshop on tree measurement this May at Harvard Forest– the universitys forest ecology station in main Massachusetts– for scientists, forest supervisors and biologists. Leverett actually wrote the book on how to determine a tree: American Forests Champion Trees Measuring Guidelines Handbook, co-authored with Don Bertolette, a veteran of the U.S. Forest Service.

As a prominent figure in a loose union of groups– the Massachusetts Forest Trust, the Native Tree Society, the Forest Stewards Guild, Friends of Mohawk Trail State Forest– committed to the identification and conservation of old-growth forest, Leveretts work has actually prompted the commonwealth to add 1,200 acres of old development to its forest reserves. Leverett named the private pines for Native leaders whom he has actually come to know over the years, largely through his first wife, Jani A. Leverett, who was Cherokee-Choctaw, and who died in 2003.

Evotourism.
Back in Mohawk Trail State Forest, after paying our aspects to the rotting remains of the mismeasured sugar maple, we tack gingerly downward through a boulder field, from fairy tale old development into a transitional forest– called an ecotone– of black cherry, big-tooth aspen, red maple and white ash. We discover ourselves unexpectedly in a broad meadow under a low sky, as a light rain begins to fall. Moving through a waist-high varietal of meadow yard called huge bluestem, we observe a couple approaching along a trail in brilliant puffy jackets. If we are familiar with the area, we hear their calls of greeting– there are really few individuals in the park today– and the lady asks. “Intimately, I would say,” says Leverett, with common good humor..
At the heart of Leveretts mission lies an easy message.

” Other people are more eloquent in the method they describe the effect of the woodland on the human spirit,” he says. “I just feel it.”.
Environment Change.
Terrific swaths of New England forest were cleared of old growth by the turn of the 20th century. This is Rowe, Massachusetts, around 1900.
This is a familiar scene for Leverett: Over the years, he has actually presented countless people to old-growth forest. Ecologists and home builders, activists and backpackers, painters and poets– no matter who hes with, Leverett informs me, he desires to comprehend their point of view, needs to know what theyre seeing in the woods. Its as if hes building up a fuller, ever-expanding map of our cumulative relationship to the natural world.
When he discovered spots of forest that looked like the Appalachian woods of his youth, Leverett initially acknowledged old development in the Northeast.

Leverett says yes, and her eyes fill with tears.
Over the decades, Leveretts work has actually made him a legend amongst “big-tree hunters,” those self-identified seekers who invest their weekends in search of the highest, earliest trees east of the Mississippi. Big-tree hunters are more like British trainspotters than gun-toting outdoorsmen: They thoroughly determine and record information– the height of a hemlock, the breadth of an elm– for inclusion in the open database kept by the Native Tree Society, co-founded by Leverett.
Starting in the early 1980s, Leverett started to notice something on his weekend hikes in the New England forests: Every so frequently, in hard-to-reach areas– the steep sides of mountains, along the edges of deep gorges– he would come across a concealed spot of forest that evoked the primeval woods of his childhood, the ancient hemlocks and towering white pines of the Great Smoky Mountains. The idea that these New England websites were ancient remnant forest flew in the face of orthodox thinking.
You call Leverett when you have a lead on the most significant or the earliest tree.
Leverett is great with a yarn, and he has informed this story– his origin story– numerous times.

Susan and her partner Kamal have actually been camping here the last couple of nights. The couple, from Boston, have currently paid their respects to other parts of the woods but have not had the ability to find the Trees of Peace. Leverett leads us throughout the field and back into the forest.

Leverett has led us to the center of the Trees of Peace. Susan and Kamal wander amongst the high pines, each stopping briefly to place a hand upon a trunk in quiet respect. The storm thats been threatening all the time never really comes. Leverett leads us up and out, back along the main trail towards the park entrance. Email addresses and invites are extended, and the couple express their gratitude. It feels like making strategies in a church car park after an especially moving Sunday service.
As Frelich says, “It ends up that truly, truly old trees can keep placing on a lot of carbon at much older ages than we thought possible. Bob was really crucial in developing that, particularly for types like white pine and hemlock and sugar maple in New England.”.
For most of the 20th century, it referred settled wisdom that the ancient forests of New England had long ago been up to the ax and saw. How, after all, could such old trees have endured the settlers endless need for fuel to burn, fields to farm and lumber to build with? Certainly, ramping up at the end of the 17th century, the colonial frontier survived on its logging operations extending from Maine to the Carolinas. The settlers and loggers missed a couple of spots over 300 years, which is why were at Ice Glen on this hot, damp August day..
I satisfy Bob Leverett in a small gravel car park at the end of a peaceful residential roadway in Stockbridge, Massachusetts. We are at the Ice Glen trailhead, half a mile from a Mobil station, and Leverett, along with his partner, Monica Jakuc Leverett, is going to show me among New Englands rare pockets of old-growth forest..
Throughout the years, and frequently in cooperation with ecologist Robert Van Pelt from the University of Washington, Leverett would establish and promote a better, more accurate way to approximate the height a tree, which is called the sine approach and is precise to within five inches. Leveretts innovations have not been simply about height: Hes likewise established precise ways to approximate trunk, limb and crown volume. The resulting larger quotes of just how much space old trees occupy have added to his discoveries about their heightened carbon-capture abilities. A recent research study Leverett co-authored with Moomaw and Susan Masino, a teacher of used science at Trinity College in Connecticut, discovered that individual Eastern white pines capture more carbon between 100 and 150 years of age than they carry out in their first 50 years. That study and others challenge the longstanding presumption that more youthful, faster-growing forests sequester more carbon than “mature” forests. The research study reinforces the importance of proforestation as the simplest and most efficient way to reduce environment modification through forests. Indeed, according to a 2017 study, if we simply left the worlds existing forests alone, by 2100 they d have caught sufficient carbon to balance out years worth of global fossil-fuel emissions– as much as 120 billion metric heaps.
Strolling through woods like these is an encounter with deep time.
As we make our method up the path, the old-growth evangelist, as Leverett is typically called, explains that though specific trees in New England have notoriously left the ax– the nearly 400-year-old Endicott pear tree in Danvers, Massachusetts, enters your mind– when ecologists talk about old growth, theyre talking not about single specimens but about systems, about uninterrupted ecological cycles with time. These are forests sustained by myriad sets of biological processes: complex, interconnected systems of continuous renewal. While there is no universally accepted definition of old development, the term came into use in the 1970s to explain multispecies forests that had actually been left alone for at least 150 years.
And thats exactly what were seeing at Ice Glen, so-named for the deposits of ice that lived in its deep, rocky crevasses well into the summer months. Hemlocks centuries old loom over knotted and thick-trunked sugar maples as sunshine thickens into shadow through a cascade of microclimates. White pines reach skyward previous doomed ash trees and bent-limbed black birch; striped maples diffuse a chlorophyll green across the forest floor through leaves the size of lily pads, while yellow birch coils its roots around lichen-covered rock; long-ago fallen, moss-heavy nurse logs go back to earth just to re-emerge as rhododendron and hemlock. In other places, maidenhair, blue cohosh and sassafras are plentiful, auguries of a nutrient-heavy, fertile forest floor. Walking through woods like these, the sort of hemlock-northern wood forests that once grew in the Appalachians from Maine to North Carolina, is an encounter with deep time..
She asks if he knows where the Trees of Peace are– a grove of the highest Eastern white pines in New England, so named, by Leverett, in honor of the Haudenosaunee belief that the white pine is a symbol of peace. Leverett called the private pines for Native leaders whom he has actually familiarized throughout the years, mostly through his very first better half, Jani A. Leverett, who was Cherokee-Choctaw, and who died in 2003. The tallest amongst them is the Jake Swamp pine, which, at 175 feet, is also the tallest tree in New England.
Given that then, Leverett has actually led thousands of individuals on tours of old-growth forest under the aegis of groups like the Massachusetts Audubon Society, the Sierra Club and the Hitchcock Center for the Environment, and published scores of posts and essays, from philosophical meditations on the spiritual significance of old-growth forest, to more scholastic work. Leverett is likewise set to lead a workshop on tree measurement this May at Harvard Forest– the universitys forest ecology outpost in central Massachusetts– for scientists, forest managers and naturalists. Leverett actually wrote the book on how to determine a tree: American Forests Champion Trees Measuring Guidelines Handbook, co-authored with Don Bertolette, a veteran of the U.S. Forest Service.
Leverett and others have discovered that a good place to discover old development is in a ravine or in the middle of other steep surface, where logging is difficult.
