GATLINBURG, Tenn. — With wrinkly skin that comes in various shades of brown, eastern hellbenders aren’t easy to spot. These giant salamanders, which average 20 inches in length, spend most of their lives nearly invisible under rocks on the bottom of cool, fast-flowing streams. In a two-year research project starting this summer, Great Smoky Mountains National Park will use a combination of technology and traditional survey techniques to solve the mystery surrounding the hellbender’s distribution in the Smokies.

“One of the major conservation questions is: Are hellbenders reproducing in our streams?” said Jonathan Cox, wetlands biology technician for the park. “And it’s really hard to find that out because their lifespan is so long that you can have a hellbender detected in a stream for multiple decades, but it may be the same individual.”

Hellbenders can live for 30 years or more, so figuring out whether the adults alive today are reproducing successfully is imperative to securing the species’ future. Hellbender populations have declined significantly over recent decades, leading the US Fish and Wildlife Service to propose that the salamander be listed as an endangered species. A public comment period on the listing proposal is open through February 11.

The species is listed as endangered in the state of Tennessee; zoo heads up years-long conservation effort

This Nashville Zoo blog post is reprinted with permission. 

NASHVILLE — Nashville Zoo’s ectotherm team, in partnership with Tennessee Wildlife Resources Agency and Tennessee State University, traveled to a waterway in Middle Tennessee to successfully release a total of 27 eastern hellbender salamanders back into the wild. These hellbenders had been raised since 2018 at the Zoo as part of a headstart program. Since the start of this conservation initiative, the Zoo has released more than 100 hellbenders into local Tennessee streams to help bolster the population of this state-endangered species.

The hellbenders released this year had been raised since 2018 at the Zoo as part of a headstart program, after being collected as eggs from streams in Middle Tennessee. Each animal was fitted with a radio transmitter earlier this year, allowing a team of graduate students to track and monitor the hellbenders throughout the summer. This is the fourth group of hellbenders to be released back into the wild since the summer of 2021.

A raft trip on the Ocoee helped save faraway Clear Creek

DUCKTOWN — We threw our backs into paddling as the raft dipped and crested.

We were on the Ocoee River in southeastern Tennessee, but Clear Creek, 118 miles away in Morgan County, was the reason for the occasion.

I joined the group, some of whom were staying in nearby cabins overnight, for rafting and a cookout.

It was part of a TennGreen push to buy and preserve 180 acres of land along Clear Creek. It will then sell 23 of those acres, which includes a house. It will donate the rest to the Obed Wild and Scenic River, an adjoining federal conservation area.

Cool water deluged us, rapid after rapid. In one case we spun with momentum. We high-fived with our paddles when we hit clear spots after a successful run.

That evening, we unwound with hot dogs, burgers both vegetarian and meat, potato salad and s’mores among other treats at the Cabins at Copperhill.

TennGreen Deputy director Christie Henderson said buying the Clear Creek land would allow for a connected wilderness area in which plants and animals could have a safe corridor. It also would preserve the view of the night sky from potential light from new houses.

Knox News: Winter a key time in salamander reproductive calendar

The woods, fields, rivers, creeks and wetlands of Southern Appalachia aren’t as barren as one would think in the midst of winter.

News Sentinel science reporter Vincent Gabrielle gives a solid rundown of why some of our amphibious denizens, including hellbenders, put themselves out there when so many other Appalachian critters retreat to burrows, dens and nests when the snow begins to blow.

“There are more salamander species that call the Southern Appalachians home than any other place on Earth. There are 30 salamander species present in Great Smoky Mountains National Park. Out of the 550 known salamander species on the planet, 77 live here in our backyards. Their bright colors make them the living jewels of Appalachia,” Gabrielle reports.

MTSU researchers document hellbender’s accelerating decline in Middle Tennessee

(Author’s note: I was aware of the hellbender before interviewing Brian Miller, but did not know the giant salamanders were present on the Highland Rim of Tennessee. Subsequent reading and interviews with other researchers, including Dr. Bill Sutton at Tennessee State University, Nashville, confirm Miller’s statements that hellbenders are vanishing from large portions of Tennessee, and Missouri. The healthy populations in portions of the Great Smoky Mountains and Cherokee National Forest may be an exception to a general trend toward extirpation and, ultimately, extinction).

Brian Miller has been researching hellbenders for decades. He serves on the faculty of Middle Tennessee State University where he teaches in the biology department and mentors younger researchers, many of whom publish their research.

He has even developed a digital “Guide to the Reptiles and Amphibians of Middle Tennessee.” The guide began more than 30 years ago as a dichotomous key for students in his vertebrate zoology class and now includes hundreds of photographs and exceeds 400 pages.

Dr. Miller researches the hellbenders of the Highland Rim, the upland that surrounds Nashville and the Great Basin. Populations of hellbenders in streams of this region are perhaps Tennessee’s most endangered.

QUESTION: I noticed that you specialize in herpetofauna. Most of the research listed on your faculty page is focused on amphibians, but with some papers on snakes. Can you comment about your research?

ANSWER: You are correct that amphibians are my primary research interest, particularly salamanders. However, I also have strong interests in reptiles, and my students and I have conducted research on various species of snakes and turtles.

When did you become interested in hellbenders?

Hellbenders have been of interest to me since I first encountered them while enrolled in a course on herpetology at the University of Missouri in 1977. I was fortunate that the professor of that course, Dean Metter, was involved with research on hellbenders and I began to assist with his research in 1978, in collaboration with Robert Wilkinson at Southwest Missouri State University in Springfield, Missouri.

Chris Petersen was working on his master’s degree with Dr. Wilkinson at that time and he matriculated to the University of Missouri a couple of years later to start on his Ph.D, which was also with hellbenders. Chris and I spent time in the field gathering data for his Ph.D. project until I moved to Washington State to work on my Ph.D.

I was hired into the biology department at Middle Tennessee State University in 1989 and began working with hellbenders in this state in 1990. At that time, I was able to locate populations in several rivers in Middle Tennessee, including a large population in the Collins River. I decided to concentrate my efforts on this population and one in the Buffalo River.

Of note, the population I worked with in the Collins River was dominated by large adults, whereas the population in the Buffalo River consisted of many age classes, including young individuals.

The Collins River situation was like what I was familiar with in Missouri and Arkansas populations. Unfortunately, by the early 2000s the population I was working with in the Collins River was gone; however, populations remain in the Buffalo River. My research with hellbenders during the past decade has been concentrated in streams in the Western Highland Rim.

Do you work with both subspecies, the Ozark, and the Eastern hellbender?

I worked with both subspecies while a student at the University of Missouri when assisting with projects in the Metter lab, but since I moved to Tennessee, I have worked only with Tennessee populations.

What do you perceive as the greatest threats to hellbender populations?

I am not certain why most populations of hellbenders are in decline rangewide, but suspect that habitat alteration, including sedimentation, and disease are involved in many if not all areas where declines are occurring. Lack of recruitment of young is a common theme of populations that decline.

New hellbender exhibit at Chattanooga Zoo will serve as a hub for cooperative research

Thanks to grants from two generous organizations, some oft-elusive hellbenders have a new home at the Chattanooga Zoo. The Hiwassee Education and Research Facility is nearly complete, and it features hellbender exhibits and a classroom. The exhibit includes juvenile hellbenders hatched from eggs collected from the Duck River in central Tennessee in 2015.  

The zoo is also fabricating a stream environment exhibit that will house nine larger sub-adult hellbenders, each about 10 years old and 14.5 inches long. Visitors can observe hellbenders feeding in the completed exhibit, but it will be open only during limited hours. After the project’s completion, the zoo plans to partner with researchers who hope to learn more about hellbenders. 

“The Chattanooga Zoo is thrilled at the introduction of its new Hiwassee Hellbender Research Facility,” zoo officials said in a statement to Hellbender Press. 

“We believe that this new facility will open rare opportunities for guests to be educated on this otherwise elusive native species, and that the project would lead to important strides made in hellbender research. 

“From all of this, our hope is for more conservation efforts made in our local waterways, also known as the eastern hellbender’s home.”

New River Gorge National Park preserves paddling and climbing paradise

When you think of national parks within a day’s drive of East Tennessee, what comes to mind? Great Smoky Mountains National Park, of course. Or perhaps Mammoth Cave in Kentucky, or Virginia’s Shenandoah. You have a new option.        

New River Gorge National Park and Preserve, created by Congress Dec. 27, 2020, by way of a pandemic relief bill, is America’s 63rd and newest national park. Located in southern West Virginia, the 72,186-acre park and preserve protects land along both sides of a 53-mile stretch of the New River, which is famous for its world-class whitewater. It’s walls rise up to 1,400 feet, attracting rock climbers from across the country.

The New River Gorge, known locally as “The New,” currently welcomes about 1.4 million visitors a year. It’s within a day’s drive of 40 percent of the U.S. population, and is expecting an initial 20 percent increase in visitation this year because it is now a national park with national attention.

Local merchants and business owners are already touting the economic benefits, including new jobs in in-store retail and dining, two industries decimated by the Covid-19 pandemic.

“We’re super excited about it,” Cathedral Cafe manager Cassidy Bays said. She said the cafe, just minutes from the park, plans to increase staff and extend hours. “We’re even building an outdoor patio to increase dining space,” Bays said.

And this is not your grandfather’s West Virginia: Locavores can find locally sourced food and lean into a vegan juice bar. Several community-supported agriculture (CSA) and co-op farms are a main source of the cafe menu. “We actually cater to locavores. We are a farm-to-table restaurant” Bays said.

Help and hope for hellbenders ... and humans

Hellbenders get help in face of new challenges, increasing threats

Snot otter. Mud devil. Lasagna lizard. Allegheny alligator. For a creature with so many colorful nicknames, the hellbender is unfamiliar to many people, including millions of visitors to Great Smoky Mountains National Park.

Julianne Geleynse wants to change that. The resource education ranger is tasked with teaching the public about the natural wonders the park protects within its borders in hopes of mitigating damage to natural resources caused by the millions of visitors, young and old, who enter the park each year.

With a visitor-to-ranger ratio of around 170,000 to 1, communicating with visitors is an ongoing challenge that requires unique solutions. Feeding wildlife and littering are perennial problems, but sometimes new issues emerge. Such was the case in 2017 — and again in 2020.

Heedless craze wreaked havoc

In 2017, researchers in the park were alarmed to find that hellbender numbers in traditionally healthy populations had dropped. An entire generation of subadult hellbenders seemed to be missing. The most glaring sign of the problem was the presence of dead hellbenders where visitors had moved and stacked rocks in park streams. Moving rocks to create pools, dams and artfully stacked cairns may seem harmless enough when one person partakes. But when hundreds of visitors concentrate in a few miles of stream every day for months on end, the destructive impact is significant. Viral photos of especially impressive cairns can spread on social media and inspire an army of imitators.

Why does moving rocks harm hellbenders? These giant salamanders spend most of their lives wedged beneath stones on the stream bottom. They live, hunt and breed beneath these rocks. In late summer, when temperatures still swelter and visitors indulge in their last dips of the season in park waterways, hellbenders are especially vulnerable as they begin to deposit fragile strings of eggs beneath select slabs. Simply lifting such a rock nest can cause the eggs to be swept downstream and the entire brood lost. As the researchers observed in 2017, moving and stacking stones can even directly crush the bodies of adult hellbenders.
