Spring City set to celebrate a rare denizen of Walden Ridge almost decimated by drought

SPRING CITY — Nokian Tyres will serve as presenting sponsor of Laurel Dace Day, a community celebration of an endangered fish, set for Saturday, May 17, in Spring City.  

The inaugural event led by the Tennessee Aquarium raises awareness of the laurel dace, a critically endangered fish found only in the Walden Ridge area 20 miles from Nokian Tyres’ North American factory in Dayton. 

Laurel Dace Day features a 5K race and half-mile family fun run, followed by a festival at the Spring City Nature Park with live music, a farmers’ market, local vendors and conservation education. The event is free to attend, other than registration fees for participation in the races. 

Community members can learn more about the event and register for races at TNAqua.org

Drought prompts emergency rescue of one of America’s most endangered aquatic species

CHATTANOOGA — Few things trigger louder or more distressing alarm bells among freshwater biologists than watching a waterway dry up during a severe, prolonged drought. That’s especially true when the disappearing stream is home to one of America’s most imperiled fish.

In late July, reports of dramatically withered streams atop Walden Ridge north of Chattanooga spurred an emergency rescue operation to prevent the extinction of the federally endangered laurel dace, which scientists consider to be among the 10 most at-risk fish in North America.

This effort was carried out by representatives from the Tennessee Aquarium, the U.S. Fish and Wildlife Service, and the University of Georgia’s River Basin Center in coordination with the Tennessee Wildlife Resources Agency. In all, 105 adult laurel dace were removed from dangerously dry streams and successfully relocated to the Tennessee Aquarium Conservation Institute (TNACI) near downtown Chattanooga.

All but one of the collected fish survived the relocation and are now thriving in temporary human care, where they will remain until conditions in their few native streams are sufficiently improved for them to be returned safely.

This laurel dace (Chrosomus saylori) was among dozens other collected from a stream on Walden Ridge north of Chattanooga to save the fish from drought. In the last 12 years, this minnow’s range has drastically dwindled to just two streams, and scientists consider it one of North America’s 10 most imperiled fish species.

A crimper is attached to the back of a tractor on a farm in the Sequatchie River Valley. A relatively recent agricultural technique, crimping has been shown to reduce farmers’ input costs and improve soil quality. Recently, USDA approved funneling $10 million into a six-county region of Southeast Tennessee. This money will fuel conservation-minded improvements for landowners, including lowering the cost to rent equipment like crimpers and subsidize the planting of cover crops to improve soil health and reduce sedimentation in nearby streams.  Tennessee Aquarium

Targeted collaborative conservation will help local agricultural operations improve soil and water quality and protect aquatic life

CHATTANOOGA — Tennessee is as much a patchwork quilt of farms as it is an intricately woven lacework of streams and rivers. Soon, farmers and the aquatic life living alongside them will reap the benefits of $10 million in federal funds to support water-friendly agricultural improvements in the rolling uplands of the state’s southeastern corner.

The U.S. Department of Agriculture (USDA) approved the allocation of more than $197 million to support Regional Conservation Partnership Programs (RCPP) throughout the nation. These initiatives promote coordination between USDA’s Natural Resources Conservation Service (NRCS) and partnering organizations that are already engaged in conservation efforts.
