Salamanders are under siege in a changing world

Salamanders are extraordinary creatures. Some of these astonishing amphibians boast vibrant colors and patterns while two-thirds of all species are lungless and able to breathe through their skin. All salamanders have the remarkable ability to regrow limbs, tails, and even parts of their heart and brain, a rare ability in the animal kingdom. 

More salamander species live in the Appalachians than anywhere else in the world. Fifty-four species of salamander call Virginia home.

Unfortunately, the impacts of climate change, habitat loss and pollution pose a real danger to these sensitive creatures. Increased temperatures, changing humidity levels, wildfires and droughts wreak havoc on salamanders, which are impacted by even small changes in habitat conditions and are often specialized to small native ranges. 

Southern Environmental Law Center’s work addressing climate change, fighting for clean water, and conservation efforts help protect all kinds of salamanders in the South. To celebrate the Endangered Species Act’s 50th anniversary, they are highlighting some of the endangered and threatened salamanders of our region.

Drought conditions threaten some of the nation’s most-endangered fish species

CHATTANOOGA — The endless parade of sunny, cloudless days in Chattanooga for the last two months may seem like the stuff of dreams to anyone planning an outdoor activity. However, this fall has turned into a blue-sky nightmare for aquatic species living in smaller creeks and streams.

“Some of those headwater pools are going to dry up, and we’ll lose large numbers of populations,” said Dr. Bernie Kuhajda, an aquatic conservation biologist at the Tennessee Aquarium Conservation Institute. “It just doesn’t look good for our headwater fish communities out there. They’re really getting stressed.”

Less than half an inch (0.42 inches) of rain fell in Chattanooga during a 72-day span between Aug. 30 and Nov. 9, according to meteorological data recorded at Lovell Field. That’s just 0.16 inches more than fell in Death Valley, California, during the same period, according to the National Oceanic and Atmospheric Administration (NOAA).

As of the latest weekly report by the government’s U.S. Drought Monitor, most of Hamilton County is now considered to be experiencing a D4 or “exceptional” drought, the Monitor’s most severe drought category.

Bad news for endangered fish species like the Barrens Topminnow and Laurel Dace.

Ela Dam on the Oconaluftee River in Cherokee. The dam is slated for removal to benefit aquatic species and the Eastern Band of the Cherokee Indians.  Erin McCombs

Ela Dam Removal Coalition moving forward after $4 million grant from U.S. Fish and Wildlife to commence river restoration project

CHEROKEE — American Rivers is working with a team on a massive effort to remove the Ela dam and restore the land and Oconaluftee River to its natural condition. Partnering with the Eastern Band of Cherokee Indians (EBCI), American Rivers is part of a coalition of federal, state, public, private, and non-profit organizations that has formed to remove the Ela dam.

Truly a village effort, the Ela Dam Coalition includes the EBCI, American Rivers, Mainspring Conservation Trust, the North Carolina Wildlife Resources Commission, the U.S. Fish and Wildlife Service, the Southern Environmental Law Center, the Environmental Protection Agency, American Whitewater, Swain County, the Army Corps of Engineers, and Northbrook Carolina Hydro II.

“Healthy rivers are essential to all life, and removing a dam is the fastest way to restore a river’s health. We appreciate this initial investment by U.S. Fish and Wildlife Service in  the restoration of the Oconaluftee River. We look forward to working with them to leverage this investment to fully realize this project to revitalize fish and wildlife habitat and restore vital cultural connections. We are grateful to the Eastern Band of Cherokee Indians for their leadership, and for the partnership of Mainspring Conservation Trust,” said Tom Kiernan, American Rivers President and CEO.  

Blocking the Oconaluftee River’s natural flow impacts the aquatic habitats of many native fish, mussels, birds, and other wildlife which require it for sheltering, feeding, reproducing, and thriving in their natural environment. The removal of Ela dam will result in a cultural reconnection of the Oconaluftee River to the Cherokee people and the Qualla Boundary. 

The Oconaluftee River is home to 11 sensitive and rare aquatic species, some of which are only found in a few streams and rivers in western North Carolina, including the federally endangered Appalachian elktoe freshwater mussel, the Sicklefin Redhorse (NC Threatened), and Eastern Hellbender (NC Special Concern). Once complete, 549 miles of the Oconaluftee River watershed will be restored and expand habitat for these species. 

Rhea County — Watts Bar Reservoir created in 1942, has remained a consistent bass fishery according to data collected over the past decades. Reservoir biologists are hopeful that a recent catch is reflective of Florida largemouth bass stocking efforts started in 2015. 

Randy Miller of Spring City caught an 11.22-pound largemouth bass on the reservoir and graciously shared the photo with reservoir biologist Mike Jolley. Jolley, an employee with over three decades of professional experience, grew up on the lake and has intimate knowledge of its waters. Jolley shared, “We routinely evaluate our fisheries in reservoirs, including Watts Bar, to assess overall health of population dynamics. Some anglers have questioned the status of the bass fishery in this lake. I’m happy to share that Watts Bar has remained a consistent fishery based on long-term, routine data collection.”
