Survey work will span Southern Appalachian forests devastated by historic 2024 hurricane, floods

BLACKSBURG — Virginia Tech and its Department of Fish and Wildlife Conservation, in partnership with the U.S. Department of Agriculture’s Forest Service Southern Research Station, received an $8.8 million grant to address environmental impacts from Hurricane Helene in the Southern Appalachians.

The initiative will be carried out through the Center for Aquatic Technology Transfer, a Forest Service office in Blacksburg that focuses on aquatic ecosystem science and management in national forests.

Virginia Tech will lead the human resources component, hiring and training technicians and crew leaders to conduct fieldwork. With the ability to call on current graduate students as well as connections to alumni with experience conducting analysis in a forest environment, the university can rapidly contract 20 employees to form teams and begin critical data collection in early 2026.

The benefit to the university comes in the experience students receive in providing this vital field research.

Introduced species are changing how seeds move on islands, global study shows

Max Esterhuizen is the Virginia Tech College of Natural Resources and Environment director of communications and marketing.

BLACKSBURG — When birds, bats, and reptiles eat fruit, they help keep forests healthy by carrying seeds away from parent trees. On islands around the world the balance of which animals eat fruit and whether those animals disperse or destroy seeds has shifted dramatically.

A new study published Oct. 7 in the Proceedings of the National Academy of Sciences found that species introductions, more than extinctions, are reshaping this ecological process across 120 islands worldwide. The changes matter because seed dispersal drives forest regeneration, plant diversity, and long-term ecosystem health.

Virginia Tech ecologist Haldre Rogers, associate professor in the College of Natural Resources and Environment and the Department of Fish and Wildlife Conservation, was part of the international research team. Rogers contributed data from the Mariana Islands, a region where invasive brown tree snakes have wiped out most native forest birds. On Guam, the loss of birds and fruit bats has nearly erased natural seed dispersal, creating one of the most extreme examples anywhere.

According to the study, large-bodied flying animals that once dispersed seeds are being lost, while many of the newcomers are mammals that eat fruit but destroy the seeds.

Deer baiting, endangered fish on tap for Fish and Wildlife Commission

TWRA logo

CHATTANOOGA — The Tennessee Fish and Wildlife Commission will hold its final meeting of 2025 at the Tennessee Aquarium (Lupton Room) on Dec. 4-5. Committee meetings begin at 1 p.m. Dec. 4, with full commission proceedings continuing at 9 a.m. Dec. 5. Both meetings will be streamed on Youtube.

The commission will have three rule-making hearings, which were previewed by Tennessee Wildlife Resources Agency staff at the TFWC’s October meeting in Nashville. To view the October TFWC meeting, click here. They pertain to the deer-baiting privilege license (only on private or leased lands), the North Cumberland OHV permit, and changes to the endangered or threatened species list.

One species, the teardrop darter, is under consideration to be added to the state Threatened and Endangered Species list. It is only found in Tennessee and Kentucky, where it occurs in the Barren and Green river systems. Two species, the Clinch dace and Sequatchie darter, are proposed to be removed from the list because they are not recognized by the American Fisheries Society.

Leading up to the rule-making hearing, Wildlife and Forestry Division Assistant Chief Mark McBride and wildlife veterinarian Dr. Dan Grove will present background information on the Deer Baiting Privilege License during Thursday's committee meetings. Expected impacts of baiting on deer, deer harvests, impacts on other species, and CWD will be among the topics discussed.

Hatchie Bottom property will join more than 30,000 acres of protected lands along river corridor

Lee Wilmot is a public information officer for the Tennessee Wildlife Resources Commission.

NASHVILLE  — The Tennessee Wildlife Resources Agency in partnership with The Nature Conservancy of Tennessee (TNC) and The Conservation Fund (TCF), announced the acquisition of the Hatchie Bottom property, a 7,457-acre expanse of ecologically rich bottomland hardwood forest along the Hatchie River.

The acquisition represents a major milestone in Tennessee’s Conservation Legacy initiative and fulfills a longstanding priority in the Tennessee State Wildlife Action Plan to protect and preserve critical wildlife habitat. The property will be managed as a new wildlife management area (WMA), and will also provide new opportunities for hunting, fishing, wildlife watching, and outdoor recreation.

“The Hatchie Bottom acquisition is a powerful example of what we can achieve when conservation partners come together with a shared vision for Tennessee’s natural heritage,” said Gov. Bill Lee. “This acquisition reflects our commitment to safeguarding the state’s most treasured landscapes while expanding opportunities for Tennesseans to connect with the outdoors. It’s an investment in our environment, our communities, and the generations to come in the Volunteer State.”

Long-term restoration efforts lead comeback of species, missing since 1970s

CHATTANOOGA — The Tennessee Aquarium’s longest-running conservation program is celebrating major developments that have biologists and wildlife managers brimming with excitement.

Massive, ancient and long-lived, the lake sturgeon has been extirpated (locally extinct) in Tennessee since the 1970s. The effort to re-establish this state-imperiled species began in 1998 with the formation of the Southeast Lake Sturgeon Working Group, a collaborative partnership between non-profits like the Aquarium as well as universities and state and federal agencies.

Since the start of reintroductions in 2000, working group members have raised and released more than 430,000 lake sturgeon into the Tennessee and Cumberland river watersheds.

The cumulative effect of that work is already changing the lake sturgeon’s fortunes. This year, the species’ conservation status in Tennessee decreased from endangered to threatened, an adjustment that reflects the long-term impact of the restoration program, says Dr. Anna George, the Aquarium’s vice president of conservation science and education.

Baby Tan Riffleshell tagged and ready to be released in the Big South ForkEndangered baby tan riffleshells are shown tagged before release in Big South Fork. Biologists are successfully reintroducing the mussel tp the area, according to research data. National Park Service

Endangered species seems to be on upswing due to reintroduction; points to water purity

ONEIDA  An endangered freshwater mussel species in the Big South Fork National River and Recreation Area is showing signs of natural population increases for the first time. The tan riffleshell (Epioblasma walkeri) is an endangered mussel found in only a few locations within the Big South Fork of the Cumberland and the upper Clinch rivers. The National Park Service has been collaborating with the Kentucky Department of Fish & Wildlife Resources to monitor the status of this rare species.

Staff from both agencies have been working together recently to recover the Big South Fork populations of this species by supplementing their numbers. Male and female tan riffleshell mussels were collected from Big South Fork and used to produce thousands of baby mussels. These small mussels have been added to limited locations where the species is known to exist at Big South Fork over the last few years.

Oak Ridge recreation center stores power in ice

OakRidgeSeal

OAK RIDGE — The city is investing in a new cooling system for the Oak Ridge Recreation Center at 1403 Oak Ridge Turnpike.

The recreation center includes a game room with pool tables and arcade games, as well a gym and an indoor pool. In a news release, city government described the new cooling technology as innovative and “designed to improve operational efficiency, lower electricity costs, and reduce carbon dioxide emissions for the facility while supporting the growth of a local clean-tech company.”

That company is Shift Thermal and its system stores energy in the form of ice, made during off-peak hours when power is cheapest and cleanest.

“During the hottest parts of the day, when electricity demand and costs are at their highest, the stored ice supplements the building’s air conditioning, which then improves performance and reduces the strain on the power grid,” Shift Thermal CTO Mitchell Ishmael said in the news release.

The company uses an immiscible working fluid to circulate through the system, eliminating traditional ice-storage heat exchangers. This design simplifies installation, increases efficiency, and lowers costs for large-scale cooling systems, the news release stated.

TWRA to sample deer for CWD at check-ins

NASHVILLE — The Tennessee Wildlife Resources Agency (TWRA) will be operating chronic wasting disease (CWD) sampling stations across the state on the opening day of the 2025 muzzleloader season, Saturday, Nov. 8, to monitor the presence of CWD in white-tailed deer populations. Hunters play a crucial role in this monitoring effort by bringing harvested deer to designated sampling locations.

CWD, a contagious and fatal neurological disease affecting deer, has been detected in 18 counties, all in West Tennessee except one positive county in Middle Tennessee (Lewis County). A complete list of counties where CWD has been detected and specific test locations is available at tnwildlife.org. By participating in CWD sampling, hunters can assist TWRA in early detection and prevent the disease from spreading.

Local and state partners will continue funding park during shutdown; some critical work will be suspended

Jim Matheny is Friends of Great Smoky Mountains National Park communications director.

GATLINBURG — Amid the ongoing federal government shutdown, the nonprofit Friends of the Smokies will continue to provide funding to ensure Great Smoky Mountains National Park remains open with basic visitor services and limited staffing from through Jan. 4, 2026.
 
The latest agreement allows the popular Cades Cove Loop Road to remain open to the public along with all visitor centers and picnic areas that are normally open this time of year.
 
Friends of the Smokies joined a partnership of state and local entities that funded the reopening and full staffing of the national park from Oct. 4 through Nov. 2. During that time, all furloughed park employees returned to work, received paychecks, and continued their efforts to serve visitors and protect the park during the busiest tourism month of the year. Great Smoky Mountains National Park attracts an average of more than 1.6 million visitors each October.
 
As the national park transitions to a relatively slower visitation season, the latest agreement from Nov. 3, 2025, through Jan. 4, 2026, will reduce the funded staff positions to those directly related to basic visitor services. Many park employees will still be furloughed. 
 
The official agreement to keep the park open is specifically between Sevier County Government and the National Park Service. Under the arrangement, Sevier County pays the federal government directly and the other partners pay their share to Sevier County. The funding effort has been supported by Sevier County, the cities of Gatlinburg, Sevierville, Pigeon Forge, Blount County, the State of Tennessee's Department of Tourism, the Eastern Band of Cherokee Indians, and Friends of the Smokies.
