Old Trees and the People Who Know Them

On a cool and breezy summer afternoon, a team of seasoned ecologists and I made our way across a steep talus slope in a remote section of Vermont’s Groton State Forest: a 25-acre stand of ancient hardwoods known as Lords Hill. Tucked into the hills of the town of Marshfield, this forest is a rare remnant of an older age—one of the few places in the state where towering sugar maple, yellow birch, white ash, hemlock, and basswood have been left to grow, die, decay, and regenerate largely undisturbed for centuries.

We were there to revisit a long-term monitoring plot established decades ago and to measure the diameter of trees tagged as early as 1977. With me were ecologist and naturalist Charlie Cogbill, our leader, NEWT board member Brett Engstrom, NEWT’s Wildlands Ecology Director Shelby Perry, and Rose Paul, former director of Science and Freshwater Programs for The Nature Conservancy. We slowly and systematically worked our way across 50-by-20 meter grids, calling out data while Charlie stood at each grid’s center, clipboard in hand, scribbling notes, and confirming each measurement with familiarity and enthusiasm.

“Yellow birch. Tag number 451. Diameter 72 centimeters!” I called out across the talus slope, my voice bouncing off of moss-covered granite boulders.

Charlie, perched atop one such boulder, flips through his notes. “Yellow birch… 451… YES!” he exclaimed triumphantly. “That one put on four centimeters since 2002,” he added, grinning.

 

The Eastern Coyote: An Adaptable, Misunderstood Addition to the Northeast’s Ecology

Among the myriad species documented by wildlife cameras across Northeast Wilderness Trust’s (NEWT) wilderness preserves, coyotes are perhaps the most ubiquitous. Whether in cedar swamps, atop spruce ridges, or roaming old fields, these adaptable creatures can be found in nearly every habitat throughout New England. Yet it may come as a surprise to many that coyotes are relative newcomers to our landscape.

A Relative Newcomer

Coyotes did not appear in the Northeast until the 1940s. Beginning with European colonization, the conversion of large swathes of the eastern United States from forest to fields allowed this Great Plains species to move eastward. Along the way, coyotes interbred with remnant wolf populations in the Upper Midwest and Canada. The resulting hybrid, known as the eastern coyote, had become a larger, more robust, and wolf-like version of its western predecessor by the time it reached New England.

According to Vermont Fish and Wildlife, eastern coyotes are not considered invasive but rather naturalized—they have integrated into the native ecosystem and now partially fill the niche once occupied by wolves and cougars, which were extirpated from the Northeast by the late 1800s. The elimination of wolves, in particular, permitted coyotes to thrive, as wolves often establish territorial dominance and suppress coyote populations in regions where they coexist.

Research into coyote genetics has blurred the distinction between these former competitors. A 2014 study published in Molecular Ecology analyzed the DNA of 437 eastern coyotes and revealed a blend of several species: coyote, wolf, and domestic dog. According to the data, the eastern coyote’s genome was, on average, 64 percent coyote (Canis latrans), 13 percent gray wolf (Canis lupus), 13 percent eastern wolf (Canis lycaon), and 10 percent dog (Canis familiaris). This means that approximately 25 percent of their DNA is wolf, though individual variability can be significant. For example, a hunter in Cooperstown, New York killed a “coyote” in 2021 that was later found to be 98 percent wolf based on genetic analysis.

Coyote Ecology

The increasing abundance of coyotes on eastern landscapes has fueled misconceptions about their ecology. One frequent claim is that coyotes must be hunted to control their populations and prevent excessive deer predation. In reality, coyotes are compensatory breeders—they adjust their reproduction based on population pressures. When more coyotes are killed, the survivors tend to produce larger litters, meaning that hunting can actually increase their overall numbers. As for their effects on deer populations, coyotes are mid-level or “meso-” predators and opportunistic hunters. They primarily target small- to medium-sized prey like chipmunks, rabbits, and snowshoe hare, and while they may occasionally prey on deer or livestock, they usually only take old or sick individuals rather than healthy adults.

Coyotes’ adaptability extends into their social behaviors. The coyotes in the above video communicate and play as they move through the snowy woods of NEWT’s Moriah Wilderness Preserve in New York. Like their opportunistic diet and flexible reproductive strategies, coyotes are also adaptable in their social structures. They can range from solitary individuals to mated pairs, family groups, or even packs. This flexibility allows them to adjust to environmental conditions and survival needs. For instance, in areas where food is scarce—or where the only abundant prey species are large mammals like deer—forming a pack can provide a significant advantage.

Coyotes in the Northeast are the subject of fierce debate. But beyond the misconceptions is a species that exemplifies resilience and adaptability in a constantly changing landscape. By understanding and respecting these remarkable creatures as filling a critical ecological role, we can gain a deeper appreciation of them and the wild places they call home—a reminder that Nature’s inventiveness often comes in unexpected forms.

Warblers of the Shrublands

In my job as Northeast Wilderness Trust’s (NEWT) New York land steward, I come across a spectacular variety of bird species on NEWT preserves and easements. Beyond entertaining the birder in me, this dimension of my role also allows me to observe how land-use changes affect bird species composition. Most of the time, this involves seeing how interior forest birds respond to formerly logged lands rewilding via NEWT’s passive management approach. But sometimes, I’m treated to the surprises of different ecosystems—and the special delight that comes with the sighting of an unexpected species.

I had one such experience recently on a monitoring trip to a 60-acre conservation easement in the Split Rock Wildway in the Adirondack Park. This easement, despite its modest size, packs a big ecological punch. Upon leaving my vehicle, I experienced a landscape I know well. Water rushed over a waterfall while Eastern hemlocks towered above. Further on, an enormous rock face covered in moss and ferns emerged from behind the trees. This was familiar territory for me and for NEWT: an older forest, tranquil and wild.

But as I journeyed on, the landscape became less familiar. By the time I had reached the furthest point from my vehicle, the old forest had transitioned to young successional forest and shrubland. A deer path was the only clear way through this area; dense woody vegetation dominated the scene, with a few younger trees reaching taller than the shrubs.

As I walked through the maze of foliage, I froze in place when from a nearby shrub floated the song of a bird I had never seen before: a Blue-winged Warbler (Vermivora cyanoptera).

These songbirds are shrubland specialists. Their range has expanded northward since European colonization, when settlers cleared much of the Northeast’s forests for farmland. As many of those farms were abandoned, shrublands grew up in their place, creating vast new swaths of suitable habitat for the species.

These human-induced changes to the landscape were great news for Blue-winged Warblers, but not so much for another closely related songbird, the Golden-winged Warbler (Vermivora chrysoptera). Golden-winged Warblers are also a species of shrubby habitats, but they tend to nest in wetlands and then finish out the breeding season in the older forests like the one in which I started my day. The two species are nearly genetically identical, but the Blue-winged Warbler’s northward expansion has led to a dramatic decline in Golden-winged Warbler numbers. The latter often loses out when the two species compete for habitat and resources.

Upon further investigation, I spotted the songster, and found myself even more floored. The bird I spied looked like a Golden-winged Warbler, but was singing like a Blue-winged! The star of my shrubland show was what is known as a Brewster’s Warbler (Vermivora chrysoptera x cyanoptera), a hybrid resulting from interbreeding between Golden- and Blue-winged Warblers.

This was not a species I expected to see that day—or any other day, given that I generally work in the kind of towering forests I described earlier, and that both species specialize in early successional habitat. But it was a great reminder of the importance of a diversity of ecosystem types across the landscape. This shrubland will continue its reversion to forest over the coming years, but the adjacent, state-owned field to the easement’s north will continue to provide the shrubby habitat both species require—and the Golden-winged Warblers will have old forest right next door for their post-breeding needs.

This is a terrific example of the landscape vision of the Wildlands, Woodlands, Farmlands and Communities collective, of which NEWT is a member: a Northeast of diverse land uses and habitats, where wildlands sit side by side with timberlands and farms in a vibrant tapestry of ecosystems and dazzling biodiversity.

Studying the Rewilding Long-Game: Ecology Research on NEWT Forest Plots

What happens when a forest is given the freedom to rewild after a long history of logging? This might seem like a question that science and ecological research have already answered; that each step of the rewilding process has been mapped out with great precision, telling us exactly what happens in the absence of active management.

After all, we know very well what happens under active management. Many land managers work hard to produce the outcomes they want, constantly tweaking variables to shift species composition, adjust light levels, or thin out tight tree stands. This management leads to fairly predictable results—why shouldn’t the opposite, passive rewilding, entail the same predictability?

Northeast Wilderness Trust hosts third Learning Circle Book Group

The novel integrates recent learning about trees and old-growth forests and highlights NEWT’s belief that We are One of Many.

The Learning Circle book group will meet via Zoom on three Wednesdays, January 29, February 19, and March 12, from 7:30 pm to 8:30 pm EDT. Three sessions will allow participants to get to know each other and to divide the reading and discussion into three parts. The January 29 session will cover the first 150 pages of The Overstory.

If you are interested in participating, please register below by December 31, 2024. Details on the sessions and Zoom link will be emailed to registered participants in early January 2025. You may participate even if you can only attend two of the three sessions. David Hindin, a NEWT supporter who facilitated the first two Learning Circle book groups, will again be our facilitator.

We look forward to meeting you!

Rare Plants Thrive on the Rewilding Shores of Muddy Pond

The Plymouth Rose Gentian (Sabatia kennedyana) shines like a pink sun when it blooms. This rare species occurs on shorelines and in wetlands from southern Rhode Island to the north shore of Massachusetts. The Gentian’s limited range and sensitivity to changes in water level and quality, as well as the destruction of wetlands along the Atlantic Coast, threaten the species: in Rhode Island it is endangered, and in Massachusetts it is classified as uncommon and of special conservation concern.

Northeast Wilderness Trust Honored at Adirondack Council’s “Forever Wild Day”

In view of the mountains that inspired Northeast Wilderness Trust’s (NEWT) founders to create the organization more than 20 years ago, Board members and staff gathered at Heaven Hill Farm in Lake Placid, NY on Saturday, July 13 to receive the Adirondack Council’s “Conservationist of the Year” award. President and CEO Jon Leibowitz accepted the award on behalf of the Wilderness Trust’s Board and explained the special place the Adirondack Park holds in NEWT’s history and mission.

“The Wilderness Trust’s founders’ chief inspiration just over two decades ago was right here; it was the Adirondack Park and the principle that underpins it: trust in wild, untrammeled nature. This ecocentric worldview drives every decision we make, animating every dimension of our work.”

Leibowitz went on to note that, fittingly, the Park was the site of the Wilderness Trust’s first conservation project: Split Rock Wildway, a series of protected parcels stitching together a vital wildlife corridor between Lake Champlain and the Adirondack Mountains. Today, the Wilderness Trust safeguards more than 10,000 acres in the area, including at properties like the Grasse RiverMoriah, and Eagle Mountain Wilderness Preserves, and via conservation easements as part of the Wildlands Partnership program.
