Scientists are using cutting-edge research in their efforts to restore Southwest Washington’s Ellsworth Creek Preserve, in hopes of easing the impacts of climate change.
Standing between nearly uniform rows of hemlock trees, scientist Tiara Moore clutched a tiny vial of evidence.
Filled with dirt and no bigger than her pinkie finger, the vial contained traces of hundreds, perhaps even thousands of creatures that had oozed by, crawled past or fluttered into this tiny corner of the Ellsworth Creek Preserve.
The microscopic flecks of DNA — from insects, amoebas and mushrooms — could help tell the story of a forest trying to regrow to its former might.
These forest forensics, part of a fast-growing field called environmental DNA, will tell researchers what’s living here, which, in turn, tells forest managers if what they’re doing is working here.
The soil where Moore dug for DNA was once rooted with old-growth trees common across the coastal Northwest, before decades of clear-cutting stripped them from the land.
Restoring landscapes like these helps take up and store more carbon, part of the solution to reduce the impacts of climate change.
The Nature Conservancy, a nonprofit which owns about 8,000 acres at Ellsworth, hopes Moore’s work can help in pursuit of a longtime Northwest quest: to restore its old-growth forests — rich with biodiversity — and fast.
“These are some of the most carbon-rich systems on Earth,” said David Rolph, director of land conservation for the organization in Washington. “Could we rebuild?”
The conservancy’s theory — backed by years of Northwest forest science — was that thinning and mimicking nature would create a more complex, vibrant forest with a diversity of species, more light for trees and less competition among them for nutrients.
“Any modeling you do will show you get bigger trees faster with thinning,” Rolph said. “You can manipulate and accelerate that complexity.”
The larger the tree, the more carbon can be absorbed and stored, making old-growth forests a boon to mitigating climate change.

The university clearcut a 16-acre grove of old-growth trees, drawing scrutiny at exactly the wrong time.
The seedling that sprouted in 1599 in Oregon State University’s McDonald-Dunn research forest was cut down by the public college, along with other trees more than 250 years old. The decision netted $425,000 for the university’s College of Forestry. School officials say the revenue will fund teaching, research and outreach, but it happened at a time when the university’s forestry school has accelerated other timber cuts and dipped into its reserves to fund $19 million in cost overruns on a major construction project.
The forestry school’s interim dean, Anthony Davis, has since acknowledged his mistake in approving the 16-acre cut known as the No Vacancy harvest. He has temporarily halted all logging of trees older than 160 years on the university’s 15,000 acres of research forests.
“Harvesting this stand did not align with the college’s values,” Davis wrote in a July 12 letter to the school community, first reported by the Corvallis Gazette-Times. “Moving forward, we have learned from this matter.”
The felling of the old growth trees raises questions about Oregon State’s land stewardship at precisely the wrong time. Top state leaders are weighing whether to hand over management of the 82,500-acre Elliott State Forest to the university’s college of forestry, a transfer that would quintuple Oregon State’s forest holdings.
Records reviewed by The Oregonian/OregonLive cast doubt on the university’s justification for cutting what it knew were trees as old as 260 years. Records also show the university recently allowed a separate clearcut seven times bigger than permitted under its own management plans.
Taken together, the cuts threaten the credibility of a school that has deep ties to the timber industry but says it can be trusted to do more than maximize timber production in the Elliott.

The bald cypress is on Black River property purchased by the Nature Conservancy.
Stahle led a group of media members and other interested parties on a paddling trip to the ancient cypress stand Thursday morning.
Stahle along with colleagues from the university’s Ancient Bald Cypress Consortium and other conservation groups, first discovered the trees in 2017, Science Daily reported.
Science Daily reported that the ancient trees are part of an intact ecosystem spanning most of the 65-mile length of the Black River.
The trees are scientifically valuable for reconstructing ancient climate conditions. The oldest trees extend the climate record in the southeast United States by 900 years. They show evidence of droughts and flooding during colonial and precolonial times that exceed any measured in modern times, experts say.
Less than 1% of original bald cypress forests survived the heavy logging of the past.

Of the almost 750 million acres of forest in the U.S., only about 3.5 million acres (or 6-percent), are considered old growth.
COOKSBURG PA — Old growth forests in North America are very rare. It’s estimated that of the almost 750 million acres of forest in the U.S., only about 3.5 million acres are considered old growth forests, and scientists have been debating for years on how to define them.
Cook Forest Environmental Education Specialist Dale Luthringer explains, “I think the best definition that I’ve seen so far is you’re trying to get a certain number of trees in the forest that pre-date the lumber history for that area.”
Cook Forest in Northwest P.A. was founded in 1927, and Luthringer says it’s considered one of the finest stands of old growth White Pine and Hemlock in the United States.
“By far, the ancient White Pine and the Hemlock is really what sets Cook Forest apart,” he says. “In terms of tall White Pine, we’ve got three White Pine that are in the hundred and seventy foot class. Our tallest Hemlock is just shy of a hundred and fifty feet, it’s about a hundred and forty eight feet tall.”
But this forest is not special only for the immense height of it’s trees. These towering sentries are truly ancient.
“Our oldest Hemlocks and Pines are around three hundred and fifty years old,” says Luthringer. “We have White Oak and Chestnut Oak that are approaching that, that we’ve got actual ring data, three thirty plus. The oldest known tree in the woods is actually a Cucumber Tree […] it’s on the ground now, but it’s the oldest known Cucumber Tree to science. That tree was about four hundred and forty years old.”
When the park was founded it was an effort to protect this unique environment from the ravages of the timber industry. Now almost a century later, park management must defend the Hemlocks from a new destructive force.
The invasive insect Hemlock Wooly Adelgid was discovered in Cook Forest in 2013. The tiny insect can kill trees within four to 10 years of infestation, and is ravaging forests across North America. Fortunately for the Cook Forest Hemlocks, the park was prepared for the invaders, and have been successful in protecting the cherished trees.

“Fifty inches in diameter,” Doug Wood said as he read the number off the tape measure. “That means this poplar tree is probably at least 200 years old, maybe 250. That puts it into the old-growth category.”
Old growth? Wait a minute. For years, West Virginians have been told that the state’s only remaining old-growth forest tracts are in Cathedral State Park and the Monongahela National Forest’s Gaudineer Knob Scenic Area. Wood believes there are more old-growth stands scattered throughout the state, perhaps many more.
“Based on criteria established by the U.S. Forest Service, there are plenty of places in West Virginia that qualify as secondary old-growth forest, where the forest has grown back up after being logged,” he said. “Several areas of secondary old growth have already been identified, and I’m convinced that more will be found.”
The poplar tree Wood measured stood in Kanawha State Forest, just a few minutes’ drive from the hustle and bustle of downtown Charleston – hardly a place one would expect to find old-growth forest. Wood said a sizable portion of the forest’s northern end contains many such trees.
“So far, we’ve found tracts on several pieces of public land that have old-growth characteristics,” he continued. “Here in Kanawha State Forest, but also in Watoga, Cedar Creek, Twin Falls, Cacapon, North Bend, Holly River and Beech Fork state parks.”
Wood, a retired Department of Environmental Protection water-quality official, is helping spearhead an effort to identify old-growth tracts, particularly on public lands. He scours the woods looking for big trees and the signs of old-growth habitat that surround them. When he finds a likely tract, he notifies the Old Growth Network of its presence.
“The Old Growth Network is a non-profit group interested in helping designate old-growth areas,” Wood explained. “They like the effort to be driven by the local citizenry, so they have county coordinators to help get citizens interested in identifying old-growth tracts.”
Wood said the recent effort by Gov. Jim Justice and his administration to open state parks to timbering has helped give rise to the grass-roots effort to protect any old-growth areas that might exist within those parks.
A Heldreich’s pine discovered in southern Italy has been thriving in a remote part of a national park for 1,230 years.

A new University of Vermont study finds that harvesting trees in a way that mimics old growth forests not only restores critical habitat for animals and plants, but also stores a surprising amount of carbon…
The “old growth” engineering technique succeeded in creating diverse habitats. But the kicker, Keeton says, is that it has also allowed the forest to store a significant amount of carbon, much more than several other conventional tree selection harvesting techniques. That’s key to fighting climate change.
Now, forests that are left alone — with no trees harvested — store the most carbon. But Keeton’s study is finding that it is possible to manage the forest to maximize carbon capture, and still keep it a working forest.
“This greater amount of carbon storage as compared to the conventional treatments was actually a combination of having left more trees behind in the first place, and growth rates that were actually 10 percent higher in this treatment as compared to the conventional harvest,” Keeton says. “And that was really surprising.”
Keeton says after 10 years, the old growth forest management plot stored nearly as much carbon as the unlogged control forest. It came within 16 percent of carbon storage in the unharvested plots.
