Chestnut researchers rally to fight the blight for good
Chestnut trees disappeared from 200 million acres of forest from northeast Mississippi to southern Maine 100 years ago. The social and ecological significance of such an event, which led to the loss of at least 1 billion trees, can be hard to understand today.
The massive die-off of the American chestnut left a big hole in the ecological fabric of Southern Appalachia and beyond. The tree dominated the forests in size and in the ecological and human services it provided.
While no tree could fully substitute an American chestnut in providing food for wildlife, naturally increasing acorn production from oaks served as a major food source bridge for wild turkey, bobwhite, white-tailed deer and squirrels. The oaks helped fill in the so-called “chestnut gap.”
Try as they might, the oaks never produced the same bountiful harvest.
Now with the work of the 3BUR (Breeding, Biotechnology and Biocontrol United for Restoration) the fight to protect the American chestnut and restore it to the throne of the forest is again in motion.

Got sprawl? It’s past time to help young farmers access land
I’m not a farmer, I’m a hiker. I live in a shady mountain gap and can’t grow a fully ripe tomato in the summer — not to mention that the half-acre parcel of land that I call home includes a significant portion of river bed. But as a 20-year resident of rural Blount County, a gateway to Great Smoky Mountains National Park, I’ve watched the steady disappearance of farms over time, and I have wondered what can be done.
This is why I rose at 4 a.m. for a trip to Nashville, planning to arrive before my alarm would normally sound. It will be my first time lobbying the state legislature and my first time meeting in person with the organizers of the Southeast Tennessee chapter of the National Young Farmers Coalition — known as “Young Farmers” — who I’ve been Zooming with for the better part of the year. We are all headed to Ag Day on the Hill to advocate for young and beginning farmers and the preservation of farmland for future generations.

The State of Bats: Grim news for our winged mammals
The big brown bat feeds on beetles, flies, moths, and true bugs, which it catches and eats while in flight. It is widespread across the Southern Appalachians and forages for food by flying slow, straight courses over water, forest canopies, wooded clearings, and around city lights. J. Scott Altenbach via Georgia Department of Natural Resources
North America’s first State of the Bats report gives a sobering outlook for the winged mammals. According to the North American Bat Conservation Alliance report:
- More than half of the 154 known bat species on the continent could face severe population declines over the next 15 years.
- During that time, up to 82 percent of bat species will be negatively affected by climate change, especially extreme drought and temperatures.
- The scope and severity of threats — including habitat loss, wind turbines and the deadly bat disease white-nose syndrome — are increasing.
The news isn’t all bad. The report outlines ways to help and emphasizes the wide-ranging benefits of bats, from improving crop yields to eating insect pests. It also highlights the promise of focused, collaborative conservation efforts.
Case in point, the lesser long-nosed bat was once endangered in Mexico and the U.S. But thanks to international efforts, it is now delisted and recovered in both countries.
The North American Bat Conservation Alliance is another example. The coalition involving the U.S., Mexico and Canada created the 2023 State of the Bats report with Bat Conservation International and others.
“Bats face many challenges and the conservation landscape is increasingly complex,” said Dr. Jeremy Coleman, alliance co-chair and white-nose syndrome coordinator for the U.S. Fish and Wildlife Service. “While there is more to do, the level of international collaboration we have achieved for bat conservation in North America is a bright spot and a cause for optimism going forward.”

In the existential battle between Smokies swine and salamanders, the hogs have the upper hand
Written by Ben PoundsEfforts to eradicate wild hogs, which have a damaging effect on salamanders and other communities in the Great Smokies, have been ongoing with mixed success for decades. National Archives
Researchers quantify the effects of feral hogs on Smokies salamander populations
GATLINBURG — A recent study investigating the relationship between Great Smoky Mountains National Park’s beloved salamanders and its hated hogs concluded that the rooting of feral pigs decreases the abundance and diversity of Smokies salamanders.
Alexander Funk of Eastern Kentucky University said the effects of feral hogs on salamanders from the family plethodontidae were mixed and varied depending on the season.
Generally, across seasons and especially in the summer, the hogs’ foraging seemed to hurt salamander abundance and diversity. Funk is a student under Eastern Kentucky University’s Director for the Division of Natural Areas Stephen Richter but had help from Benjamin Fitzpatrick of the University of Tennessee at Knoxville. The study involved Funk going out late at night on Balsam Mountain in the spring, summer and fall of 2022.

Foundational ecology moves from before times to nowadays in the Smokies
GATLINBURG — In the Middle Ages, salamanders were thought to come from fire. A log set on the hearth would send them scurrying out of the rotten wood, startling those who had gathered around for warmth. We now know that salamanders, of course, come from water — even the European fire salamander with its flame-like yellow markings.
Over the last 20 years of getting my boots soggy in Great Smoky Mountains National Park, I know these creatures to thrive in the clean, shallow streams and trickles of this temperate rainforest, where annual precipitation is higher than anywhere in the U.S. save for the Pacific Northwest.
One way to become acquainted with the park is through the water that veins through the hills and is transmuted into vapor that floats on the air in misty silence. After a rain, you can slake your thirst from the pools formed in the creases of broad rhododendron leaves. Sit by a shallow, fishless stream for long enough and you might spot the quick movement of a salamander tail, maybe a flash of orange or brown, or notice a tiny black amphibian face peeking out from behind a smooth stone in the creek.

How the 2016 Great Smoky Mountains National Park wildfire affected salamanders and other life, six years on
GATLINBURG — The disastrous Chimney Tops 2 wildfire of 2016 occurred some six years ago, but researchers are still looking at its ecological effects.
The Discover Life in America 2023 Colloquium brought together researchers this month from different fields and universities to present findings on research in Great Smoky Mountains National Park.
Researchers presented on many topics, ranging from trout to the history of the Mingus family in the park.
One such presentation, the first of the day, from William Peterman, associate professor in wildlife ecology and management at Ohio State University, focused on the effects wildfires had on salamander populations, which he described as negative.
Other presenters touched on the wildfire’s effects as well, including its effects on vegetation and its beneficial effects on the diversity of bird species.
“Smoky Mountains is the self-proclaimed salamander capital of the world,” Peterman said. He focused his study on the plethodontid family of salamanders, which breathe through their skin.
“Kind of think of them as a walking lung,” he said.
Tennessee Citizens for Wilderness Planning Executive Director Sandra Goss is nearing retirement after decades of tending to the environmental issues facing East Tennessee and the Cumberland Plateau.At cusp of retirement, Sandra Goss reflects on what she and others have saved
This is the latest installment of an occasional series, Hellbent, profiling citizens who work to preserve and improve the Southern Appalachian environment.
OAK RIDGE — I can see the view of Lilly Bluff Overlook at Obed Wild and Scenic River in my mind. The trees are bare save some evergreens. The stream I love to splash around in during warmer times is flowing between the slopes.
I can see the cliff face in the distance. It would be a great place to interview Tennessee Citizens for Wilderness Planning (TCWP) Executive Director Sandra Goss; after all she and her organization helped preserve the area. It’s also near the places she grew up. She cited the experiences as inspiring her conservation ethic.
Earlier this winter, the Christmas tree in Oak Ridge’s Jackson Square was on its side due to icy gusts and I’ve called off meeting with Goss in person at Panera to avoid torturing her or me with the elements. We could hike, but not stand around.
I’ve seen her at TCWP Christmas parties in Oak Ridge and on hikes though, so just like Lilly Bluff, I can imagine her silver-white hair, smile and glasses as I speak to her by phone. I hear her accent, more Southern Appalachian than the Yankee-ish Oak Ridge accent I speak, nodding to her origin in Crossville.
Goss is retiring Aug. 31, and she’s looking back on her work and forward to the break.
Migrating sandhill cranes descend on Southeast

Beyond festivals, sandhill cranes pass through Southeast in increasing numbers
BIRCHWOOD — Every year in mid-January, a few thousand people gather here for The Sandhill Crane Festival because the cranes have returned. The community center at Birchwood is filled with vendors selling wildlife art or promoting conservation. The nearby Cherokee Removal Memorial at Blythe Ferry offers a chance to celebrate Cherokee culture and learn the story of indigenous people who were taken from their homes and sent on a long journey to Oklahoma.
Meanwhile, there are opportunities to see and appreciate these amazing birds through February in East Tennessee and beyond.
At least 20,000 cranes gather or pass through Hiwassee Wildlife Refuge, having come from their nesting grounds in southern Canada and the upper Midwest to winter here in the American South. Many spend the winter there, but some will continue southward to Okefenokee Swamp in Georgia and the Gulf Coast.
The crucial Amazon rainforest is nearing a point of no return
NYT: Decades of extraction have left the South American rainforest at a “tipping point.”
The Amazon has long served as a vast carbon sink, even as vegetation pumped oxygen into the atmosphere to the point it was called the “lungs of the Earth.”
But vast deforestation, despite calls to save the Amazon that originated decades ago, portends profound changes in the ecology of the huge, increasingly fragmented forest that lies mainly within Brazil.
“Just in the past half-century, 17 percent of the Amazon — an area larger than Texas — has been converted to croplands or cattle pasture. Less forest means less recycled rain, less vapor to cool the air, less of a canopy to shield against sunlight,” according to a report from Alex Cuadros.
“In one study, a team led by the researcher Paulo Brando intentionally set a series of fires in swaths of forest abutted by an inactive soy plantation. After a second burn, coincidentally during a drought year, one plot lost nearly a third of its canopy cover, and African grasses — imported species commonly used in cattle pasture — moved in.”

JEFFERSON CITY — Can you see the Sleeping Lady?
We are standing on the back porch of the historic Isaac McBee House, built in 1850, and I follow Jack Kramer’s gaze across the back lawn, over McBee Island flanked by the cold March waters of the Holston River, and to the mountains in the distance.
“She’s easier to see this time of year,” he says, because those distant hills are unobscured by the foliage of trees still nakedly waiting for spring. Indeed, I can see her — she lies with her head to the west and her toes stretched out to the east, the hills forming the rise and fall of her body.

Real or fake Christmas trees? Like most things in life, the answer is a function of time.
Nature Conservancy: Keep it real
Nothing beats the fresh aroma of a live Christmas tree, if you are into that kind of thing, but both real and fake trees carry their own load of sustainability pros and cons.
Live trees offer holiday beauty and scent and are a traditional addition to households. But they are harvested from a vast monoculture and require multiple levels of carbon-burning transport.
Artificial trees offer convenience, and can be reused for a decade. But they are largely made of plastic, manufactured in places with unsavory human rights records, and require global transit.
This article breaks it down pretty well. Maybe it’s just best to not have a Christmas tree?
UT prof: Dung beetle mothers protect their offspring from a warming world by digging deeper
Written by Kimberly S. SheldonResearch from Kimberly Sheldon at the University of Tennessee suggests insect behavior is adjusting for climate change
If the TV series “Dirty Jobs” covered animals as well as humans, it would probably start with dung beetles. These hardworking critters are among the insect world’s most important recyclers. They eat and bury manure from many other species, recycling nutrients and improving soil as they go.
Dung beetles are found on every continent except Antarctica, in forests, grasslands, prairies and deserts. And now, like many other species, they are coping with the effects of climate change.
I am an ecologist who has spent nearly 20 years studying dung beetles. My research spans tropical and temperate ecosystems, and focuses on how these beneficial animals respond to temperature changes.
