If the joy of seeing butterflies seems increasingly rare these days, it isn’t your imagination.
From 2000 to 2020, the number of butterflies fell by 22% across the continental United States. That’s 1 in 5 butterflies lost. The findings are from an analysis just published in the journal Science by the U.S. Geological Survey’s Powell Center Status of Butterflies of the United States Working Group, which I am involved in.
We found declines in just about every region of the continental U.S. and across almost all butterfly species.
Overall, nearly one-third of the 342 butterfly species we were able to study declined by more than half. Twenty-two species fell by more than 90 percent. Only nine actually increased in numbers.
Some species’ numbers are dropping faster than others. The West Coast lady, a fairly widespread species across the western U.S., dropped by 80 percent in 20 years. Given everything we know about its biology, it should be doing fine — it has a wide range and feeds on a variety of plants. Yet its numbers are absolutely tanking across its range.
Each February, for four days, the world comes together for the love of birds. Over these four days people everywhere are invited to spend time in their favorite places watching and counting as many birds as they can find and reporting them to us. These observations help scientists better understand global bird populations before one of their annual migrations.
Step 1: Decide where you will watch birds.
Step 2: Watch birds for 15 minutes or more, at least once over the four days, February 14–17, 2025.
Step 3: Identify all the birds you see or hear within your planned time/location and use the best tool for sharing your bird sightings:
If you already use Merlin or eBird, all entries over the 4 days count towards GBBC. Keep doing what you are doing! No need to register or sign-up separately for GBBC.
Note that the Great Backyard Bird Count and Project Feeder Watch are two different projects. Their observations are recorded separately. However, if you are enrolled in Project Feeder Watch and your observation days overlap with the GBBC period, you can choose to designate your feeder also as a stationary GBBC count location and submit your feeder observations to both projects. The principal purpose of GBBC, though, is to identify all birds one can see and hear. Because relatively few species of birds are attracted by feeders, it is important to obtain counts from locations beyond your feeder and beyond your own backyard to gain a better understanding of bird biodiversity.

JONESVILLE, Va. — In Lee County, Virginia Cooperative Extension Agent Amy Byington is working to stop a tiny invader posing a big problem.
Hybrid fire ants, which are well-established across East Tennessee and parts of Kentucky and North Carolina, are now infiltrating far Southwest Virginia.
“It’s just one more nuisance,” said Byington, who leads efforts in her county to report and treat the growing issue. “I get calls every week from landowners who are discovering new ant mounds on their property.”
Byington partners with the Virginia Department of Agriculture and Consumer Services (VDACS) to locate and treat the mounds with insecticide bait.
“One of my producers recently reached out and reported they had found six fire ant mounds on their farm,” she said. “The VDACS inspector later ended up counting 58. It’s a management issue and a human issue.”
As of 2024, Lee County is the only county in Virginia with a presence of hybrid fire ants, although this is expected to change in coming years as ants gradually expand their territory north and east.

KNOXVILLE — The National Champion Tree Program (NCTP) will take nominations for new Champion Trees on its website starting Feb. 28. The list of eligible tree species for the 2025-2026 register includes more than 1,200 species of trees native and naturalized to the U.S., a steep increase from the 900 species eligible for the 2024 register. It is available online in the Register of Champion Trees. Nominations for potential Champions will stay open through August 2025.
“Each year, people find ‘new’ Champions all over the country,” said Jaq Payne, NCTP director. “It could be the tree in your backyard, the tree in front of your church or the tree in one of your local parks or state forests.” For the first time in the program’s 84-year history, an additional list of “culturally important non-native” eligible species will be included to represent common, widely recognized urban species previously not found on the register.
Champion Trees are identified based on a point system including the trunk circumference, height and average crown spread. After members of the public nominate trees, the NCTP will work with state coordinators to verify the submissions and their measurements. Verified trees will be added to the program’s data management system. National Champion Trees are crowned once every two years and must be re-verified every 10 years.

GEORGETOWN — What started as a simple search for a peaceful retreat turned into an extraordinary ecological discovery.
When Mr. Owen purchased his land near Georgetown, he was looking for a place to hunt, hike and escape city life. Little did he know he’d become the guardian of one of Tennessee’s rare prairie gems.
The property’s true identity emerged when the Foothills Land Conservancy’s director of natural resources (the author of this piece) spotted something remarkable during her first visit — prairie dock, a telltale sign of native grassland heritage. This wasn’t just any piece of land; it was a lost prairie awakening from decades of forest cover, less than a half mile from the historic Gunstocker Glade along Highway 58.
The timing was perfect. A 2022 clearcut had inadvertently liberated this sleeping prairie, allowing it to breathe and bloom for the first time in generations. By its second year, the land burst into life, revealing an astonishing diversity that had laid dormant for years.
Here’s an aerial view of the Owen property in Meigs County northeast of Chattanooga on the eastern Cumberland Plateau escarpment. Native prairie plants emerged from the site of a clearcut, yielding a surprisingly vital piece of prairie. Shelby Lyn Sanders

BIRCHWOOD — The Sandhill Crane Festival is underway through Sunday in Birchwood, Tennessee. This is the 34th year of the festival. Come celebrate the return of this migrant bird. Breathe in the fresh air. Hear its call. See its dance.
With up to 20,000 sandhill cranes returning to the area each year, you’re bound to be caught up in the spectacular display of the sandhill cranes, eagles, waterfowl and more on the Hiwassee Wildlife Refuge. Volunteers will be on hand with spotting scopes, but you’re welcome to bring your own binoculars. Dress for the weather, rain or shine. A potent cold front enters the area Sunday.
Free buses shuttle attendees from the Birchwood School on Highway 60 to each of the locations. No parking is permitted at the refuge unless attendee is in possession of a handicap placard.
The American Eagle Foundation will once again be at the Birchwood School for two live performances each day, along with Nashville recording artist, Second Nature. Vendors will be set up in the gym and home-cooked meals prepared in the kitchen, including Ms. Linda’s homemade breakfast biscuits and vegetable soup.
Sukakpak Mountain lies in the Brooks Range of Alaska. Mountain environments were the subject of a conservation paper that found more protections are needed for the many differing types of montaine environments. “Mountains are super-important for biodiversity, ecosystem function, and the benefits people get from nature. We ignore them at our peril,” said a Society for Conservation Biology researcher. Bob Wick/Bureau of Land Management

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.”

Tennessee coneflower is seen in Couchville cedar glade, a prime example of cedar glade habitat that is a target of preservationists — such as the land acquired recently in Rutherford County by TennGreen Land Conservancy. The Couchville property is managed by the Tennessee Department of Environment and Conservation. It is similar in nature to the TennGreen property in Rutherford County, and is part of a nexus of such glades around the Cumberland Plateau. According to TDEC: “Couchville supports one of the largest known and best quality populations of the Tennessee coneflower (Echinacea tennesseensis), which was delisted as a federally endangered species in September 2011. Couchville also provides one of the finest examples of a glade-barrens complex and protects many rare plant species. The glades are distributed where limestone outcropping and shallow soils limit growth of perennial plants and support annual species like leavenworthia, sporobolus, and sedum. The barrens species, that also includes Tennessee coneflower, occur where soils increase and grasses like little bluestem and side oats grama become dominant. The glades and barrens interface forming a complex.” Tennessee Department of Environment and Conservation
MURFREESBORO — To close out 2024, TennGreen Land Conservancy and Allen Patton protected 50 acres of globally unique cedar glade habitat in Middle Tennessee’s Rutherford County with a conservation easement.
Called Rockdale Cedar Glades and Woodlands, Patton’s land abuts TennGreen’s Lamar Cedar Glades & Woodlands Conservation Easement, increasing this connected corridor of protected land to an expansive 256 acres. Limestone cedar glades and barrens, which are incredibly diverse but under threat from development and pollution, are found on the protected properties. This additional 50-acre easement is also within the Spring Creek HUC 12 Watershed and the Stones River Upper HUC 12 Watershed, marking it as critical habitat.
(Hellbender Press has previously reported on the special nature and importance of cedar barrens, including one located in Oak Ridge, just on the cusp of the Cumberland Plateau, which is better known for its cedar glades).

GATLINBURG — Since its origin in 1900, the Christmas Bird Count has become a holiday fixture for ever-expanding numbers of birders across the globe, giving a valuable gift to generations of wildlife scientists — a massive trove of data on bird populations in the Western Hemisphere.
This annual avian census, set to commence for the 125th time, began in an era when many bird species were facing steep declines, especially waterfowl prized for their feathers. The Christmas Bird Count was the National Audubon Society’s answer to the traditional Christmas Side Hunt, a team competition that encouraged participants to kill as many furred and feathered creatures as possible in a single outing.
“The Christmas Bird Count really got started as an alternative to those kinds of hunting efforts,” said Curtis Smalling, executive director of Audubon North Carolina. “This year is the 125th annual Christmas Bird Count, and that makes it the longest-running community science project in North America.”
Anyone can participate in the CBC, regardless of their birding skill level, by joining one of the thousands of circles, each 15 miles in diameter, that comprise the event. The organizer of each circle chooses a day between December 14 and January 5 to conduct their count. On the appointed day, all participants in the circle have 24 hours in which to tally as many birds as they can. In addition to listing the individual species spotted, they also count the number of individual birds seen and participant hours logged.
The Great Smoky Mountains region includes circles in Gatlinburg, Cades Cove, Knoxville, Franklin, Highlands, Waynesville, Hot Springs and Asheville.

OAK RIDGE — A visualization tool that tracks changes to the nation’s forests in near-real time is helping resource managers pinpoint areas with the most damage from Hurricane Helene in the Southeast.
The ForWarn visualization tool was co-developed by Oak Ridge National Laboratory with the U.S. Forest Service. The tool captures and analyzes satellite imagery to track impacts such as storms, wildfire and pests on forests across the nation.
When staff with the Forest Service’s Eastern Forest Environmental Threat Assessment Center in Asheville, North Carolina, were unable to work in the immediate aftermath of Helene due to utility outages, the ORNL-hosted ForWarn system continued monitoring the storm’s impact and providing reports. ForWarn indicated areas of severe disturbance to the forest canopy that were later confirmed by aerial photography.
“ForWarn helps quickly identify areas that may need remediation such as timber harvesting or prescribed burns as piles of felled trees dry out and potentially pose wildfire hazards,” said ORNL’s Jitendra Kumar.
KNOXVILLE — Tennessee’s 2024-25 statewide gun hunting season for deer opens Saturday, Nov. 23. The season traditionally opens each year on the Saturday prior to Thanksgiving. During gun season, sportsmen may also use muzzleloaders or archery equipment.
The statewide bag limit for antlered bucks is two. No more than one antlered deer may be taken per day, not to exceed two for the season. In Units 1, 2 and 3 there is an antlerless bag limit of three per day, and a limit of two antlerless for this season in Units 4, 5 and 6. The bag limit may only be exceeded as part of the Earn-A-Buck program or as replacement buck in a CWD positive county.
During season setting, new hunting units were implemented for this season. Hunters should refer to the 2024-25 Tennessee Fishing, Hunting and Trapping Guide for specific information about their hunting unit and complete license requirements.
Anyone born on or after Jan. 1, 1969, is required to carry proof of satisfactory completion of a hunter education class or be in possession of the Apprentice Hunter Education Permit (along with other required licenses) while hunting any species in Tennessee. Hunter education can be completed online for free along with in person options offered by TWRA.
The statewide deer hunting season will continue through Jan. 5, 2025. The second Young Sportsman Hunt is Jan. 11-12.
