“During the summer and fall of 2024, a prolonged drought emerged as a preeminent threat to the Laurel dace, a freshwater minnow native to Tennessee. During this pivotal time, the Laurel Dace Rescue Team provided for the ongoing conservation and survival of the endangered fish by developing a water level monitoring protocol and planning for individuals to be collected and brought into captivity to maintain representation from the last two wild populations. In a short period, the team collaborated to rescue, transport, and house more than 200 fish while maintaining separation of individuals from each population. The Aquarium led the ‘Race for the Laurel Dace’ fundraising campaign, which helped significantly raise public awareness of the species’ plight and secure funding to help ensure the availability of the specialized emergency care needed for the rescued individuals. The Service’s diligent work to sample, collect, transport, and care for individual laurel dace were invaluable to this effort.”

KNOXVILLE — Tennessee has a natural abundance of water resources and biodiverse ecosystems. Unfortunately, 60% of Tennessee’s waterways are not meeting federal standards.
Stream habitat has been consistently declining in the last several decades. Restoring and conserving high value riparian areas will be an essential part of combating the negative impacts of urban development.
Barriers to resources prevent communities from effectively tackling these projects on their own, severely limiting cohesive statewide efforts for water quality improvement.
Maddy Johnson will introduce practical methods of restoring a riparian area in various settings at no to low cost.
Green Drinks Knoxville is a social and professional organization that convenes open-minded folks to encourage education and conversation about the environment, green technologies, sustainable lifestyles, and more. Our events are free and open to the public. We welcome all and support racial diversity, gender equality and LGBTQ inclusivity.

Historically, Earth’s climate changes have generally happened over thousands to millions of years. Today, global temperatures are increasing by about 0.36 degrees Fahrenheit (0.2 degrees Celsius) per decade.
Imagine a car speeding up. Over time, human activities such as burning fossil fuels, have increased the amount of greenhouse gases in the atmosphere. These gases trap heat from the Sun. This is like pressing the gas pedal. The faster the driver adds gas, the faster the car goes.
The 21st century has seen a dramatic acceleration in the rate of climate change, with global temperatures rising more than three times faster than in the previous century.
The faster pace and higher temperatures are changing habitat ranges for plants and animals. In some regions, the pace of change is also throwing off the delicate timing of pollination, putting plants and pollinators such as bees at risk.
Most plant and animal species can tolerate or at least recover from short-term changes in climate, such as a heat wave. When the changes last longer, however, organisms may need to migrate into new areas to adapt for survival.

FRANKLIN, N.C. — The Little Tennessee River is home to 100 fish species alone — some found nowhere else in the world. The river and its adjacent greenway are also a beloved recreational resource for Macon County residents and tourists alike. But over the past few weeks, the banks of the river have been under assault by U.S. Army Corps of Engineers contractors, removing hundreds of trees, many of which were still alive. Take action now to prevent further damage to the river!
While large-scale debris removal continues to be a high priority in many parts of Western North Carolina in the aftermath of Hurricane Helene, the Little Tennessee River did not experience those same impacts; it saw only normal flooding. Apart from a few localized areas, like the Cullasaja River across from Walmart, there is no need for disaster recovery-type debris removal in Macon County waterways. And yet, contractors started near Tryphosa Road in Otto and have been working their way down the river, removing trees and debris from the river channel and banks in areas where no flooding impacts occurred.

NASHVILLE — A bill slashing regulations for an estimated 80 percent of Tennessee’s non-federally protected wetlands headed to Gov. Bill Lee’s desk this week after receiving approval from the General Assembly.
The bill’s West Tennessee Republican sponsors — Rep. Kevin Vaughan and Sen. Brent Taylor — said the legislation removes onerous and seemingly subjective mitigation requirements for landowners and developers.
Environmental advocates and scientists said the legislation paves the way for the destruction of Tennessee’s natural resources.
The bill passed 71-21 with one abstention in the House, and 25-6 in the Senate.
Since the 1970s, wetland regulations in Tennessee have required developers and landowners to seek permission from the state before draining or altering wetlands. The swampy areas can host diverse species, soak up rain water and filter it as it seeps into groundwater tables, recharging aquifers. Alterations to wetlands required developers to pay for mitigation — efforts to preserve or restore other wetlands nearby.
Paul Stoddard, a principal at environmental consulting firm EnSafe, unlocks the gate to the West Tennessee Wetlands Mitigation Bank in Shelby County. EnSafe planted more than 50,000 trees to restore portions of this 250-acre wetland, creating credits for developers to purchase to offset destruction of wetlands elsewhere.

LEWISBURG — Fourth-generation Middle Tennessee cattle farmer Cole Liggett lined up with scientists and environmental advocates in March to urge Tennessee lawmakers not to gut the state’s historically strong protections for wetlands.
Wetlands protection has been good business for Liggett. In addition to raising cattle, he’s a manager at Headwaters Reserve, a firm that developers pay to preserve and restore wetlands and streams so they can destroy them elsewhere, called mitigation banking. If lawmakers follow through on a plan to deregulate an estimated 80 percent of the state’s isolated wetlands, that will upend the industry in Tennessee and drive up prices for developers still required to pay for mitigation, Liggett testified.
Liggett works in a growing industry that operates more than 2,500 mitigation banks nationwide, earning an estimated $3.5 billion in revenue in 2019, according to a 2023 study funded by the Ecological Restoration Business Association.
The industry is built on demand spurred by the 1972 U.S. Clean Water Act, which requires developers to offset their damage to wetlands by building or restoring wetlands nearby.
But recent federal actions to shrink the scope of that law are pushing states to choose how strictly they will regulate wetlands. The consequences of those decisions not only threaten further degradation of land, water and wildlife, but also the fortunes of an industry that has made a big business out of conservation.

JEFFERSON CITY — The Tennessee Valley Authority has announced plans to replace the current aeration system at Cherokee Dam with new turbine technology by 2026. These upgrades, designed to improve water quality downstream, may have unintended consequences for aquatic wildlife in Cherokee Reservoir — particularly striped bass. The Tennessee Wildlife Resources Agency (TWRA) is currently evaluating these potential impacts.
The existing oxygenation lines in Cherokee Reservoir were originally installed to meet TVA’s requirement for minimum dissolved oxygen levels in water discharged below the dam. However, an unexpected benefit of this system has been the creation of a cool, oxygen-rich refuge in the reservoir during summer months — a critical survival zone for large striped bass. These fish rely on cooler, well-oxygenated water to make it through Tennessee’s hot summers, and Cherokee Reservoir provides limited natural options.

NASHVILLE — A representative from the legal firm that fought for deregulation of American wetlands at the U.S. Supreme Court spoke Wednesday in support of a Tennessee bill that would roll back protections for up to 80 percent of the state’s isolated wetlands.
Tennessee lawmakers are considering a bill that would significantly reduce requirements for development on wetlands, swampy lands that support diverse ecosystems, soak up floodwaters and recharge groundwater.
A state House subcommittee voted 7-2 to advance the bill to the full House Agriculture and Natural Resources Committee, where it will be heard on April 1.
The state’s current regulations predate the federal Clean Water Act, which imposed the first federal protections for wetlands in the 1970s, requiring developers to compensate for destroying wetlands by preserving or restoring them elsewhere.
But the erosion of federal regulations in the last two years has given states more power to decide how they will define and protect wetlands.

CHATTANOOGA — After being saved from near-certain extinction last summer and overwintering in the expert care of biologists at the Tennessee Aquarium, more than 230 critically endangered laurel dace are finally back where they belong.
Last July, a prolonged regional drought caused many Southeast Tennessee streams to dwindle and, in some cases, dry up entirely. Atop Walden Ridge north of Chattanooga, water flow ceased at Bumbee Creek and Youngs Creek, the last sites known to support populations of Chrosomus saylori, the laurel dace.
When conditions in these rapidly disappearing waterways reached a tipping point, the Aquarium led a series of emergency rescue operations to save as many of these red-bellied, highlighter-yellow-finned minnows as possible. In coordination with the Tennessee Wildlife Resources Agency and with assistance from the U.S. Fish and Wildlife Service and the University of Georgia, about 300 laurel dace — the majority left on the planet — were relocated into the safety of human care at the Tennessee Aquarium in Chattanooga and Wolf Creek National Fish Hatchery in Jamestown, Kentucky.
According to the most recent report from the USDA’s U.S. Drought Monitor, much of Southeast Tennessee is still experiencing moderate drought conditions. However, a slightly wetter-than-average February made it safe to return these rescued minnows to the wild.

GATLINBURG — 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.

Every month scientific journals publish hundreds of new papers about endangered species and wildlife conservation. It’s a firehose of information in a world that feels increasingly in flames.
We asked researchers to send us their best or favorite papers of the past year. We received submissions that offer hope, guidance, analysis, and insight into emerging threats.
Aerin Jacob, director of science and research at Nature Conservancy of Canada, sent a coauthored paper from Conservation Biology about mountains — a habitat type that deserves more attention. “People often think that mountain ecosystems are so rugged and inaccessible that they don’t need habitat protection, but that’s not true,” she wrote. “We studied six major mountain regions around the world and found that on average half of them are as modified as the rest of the world; two-thirds of them don’t (yet) meet the 30×30 global protection target; and existing protected areas don’t include the vast majority of mountain ecosystem types. Mountains are super-important for biodiversity, ecosystem function, and the benefits people get from nature. We ignore them at our peril.”

Epic flooding from Tropical Storm Helene destroyed the CSX railroad bed along the length of the Nolichucky River Gorge near Erwin. TDEC and the U.S. Army Corps of Engineers this month ordered the transportation company to stop dredging materials from the river to repair its railroad line. Jonathan Mitchell for Hellbender Press
This story was originally published by Tennessee Lookout.
ERWIN — The U.S. Army Corps of Engineers and Tennessee environmental regulators ordered CSX Transportation to stop dredging the Nolichucky River Gorge for rocks and sediment being used to shore up a rail line washed away by Tropical Storm Helene.
In separate letters issued to the Fortune 500 company this month, the Corps and the Tennessee Department of Environment and Conservation (TDEC) warned, the company’s dredging was unauthorized — and noted CSX had continued dredging activities even after being put on notice last month by both agencies.
The company is prohibited from performing “any excavation or dredging of material from the Nolichucky River or its tributaries in both Tennessee and North Carolina, the Dec. 2 letter from the Corps said. CSX must “immediately cease and desist” its dredging, TDEC’s Dec. 6 letter said.
Dredging poses serious risks to the river’s aquatic life and increases the potential of downstream flooding in the future for communities that rely on the Nolichucky for outdoor recreation and the tourist dollars it brings in, a lawsuit filed by lawyers with the Southern Environmental Law Center said last month.
