Lake sturgeon recovery links rivers and experts in Tennessee and Wisconsin

CHATTANOOGA — Just across from the iconic peaks of the Tennessee Aquarium on the shore of the Tennessee River, a group of scientists with the Tennessee Aquarium Conservation Institute gathered on an early May morning to restore a primordial fish to the state’s primary waterway.

One by one, they carefully navigated down a boat ramp at Coolidge Park before gently releasing juvenile lake sturgeon, each just under a foot in length, into the river’s shallows.

These 50 sturgeon were the final youngsters to be reintroduced from a class of hundreds of sturgeon fry that arrived at the Conservation Institute’s freshwater field station last summer. Their introduction to the Tennessee River represented the latest milestone of a decades-long conservation effort to restore this state-endangered fish.

Despite reclaiming their one-time home in the waters of the Volunteer State, these newfound Tennesseans began life some 850 miles north of Chattanooga.

The Duck landed third on American Rivers’ list of most endangered rivers in the U.S.

This story was originally published by Tennessee Lookout.

COLUMBIA — The Duck River, which winds through seven Middle Tennessee counties for more than 260 miles before reaching the Tennessee River, is among the most endangered rivers in the United States, according to a new report by the advocacy group American Rivers.

Threatened by population growth, development and climate change “urgent action is needed to safeguard this vital ecosystem,” the report released Tuesday said.

The Duck River serves as the source of drinking water for nearly 250,000 Tennesseans. Industry and agriculture depend on it, too. Often considered one of Tennessee’s most pristine waterways, it draws more than 150,000 people each year for boating, fishing and other recreation. Last year, in an effort to protect the river from a controversial plan to establish a landfill near its banks, state lawmakers designated a portion of the river in Maury County an official state scenic waterway.

City Nature Challenge logo 

KNOXVILLE — People across 13 counties in East Tennessee are urged to record animals, plants and fungi they observe for four days in late April.

City Nature Challenge 2024 is international, but the Knoxville-area challenge includes anyone in Anderson, Blount, Campbell, Claiborne, Grainger, Jefferson, Knox, Loudon, Morgan, Roane, Scott, Sevier and Union counties. It will run April 26 through April 29 via the iNaturalist app, which is available on Google play or the App Store. While the focus is largely centered on urban areas, participants don’t have to live within a city or town to record their observations.

Participants can upload photos from a digital camera to the iNaturalist website even if they lack a smartphone. Zoo Knoxville, Tennessee Butterfly Monitoring Challenge, the city of Knoxville, Ijams Nature Center, Sierra Club, South Doyle Middle School and Discover Life in America are partnering to support the project. No experience is needed to participate. Results will be announced on May 6.

california condor NPSIn September, six California condors repeatedly ventured north from their Pinnacles National Park homeland to Mount Diablo in the San Francisco Bay area, becoming the first condors seen in that area in over a century. Biologists speculate the sorties may indicate new nesting territories. Seen here is a condor deemed California condor 87 by biologists tracking the rare bird population.  Michael Quinn/National Park Service

Rare and threatened animals used innate skills and courage to recover lost territory, expand their ranges, or simply survive against the odds. Humans helped.

This article was originally published by The RevelatorTim Lydon writes from Alaska on public-lands and conservation issues. He has worked on public lands for much of the past three decades, both as a guide and for land-management agencies, and is a founding member of the Prince William Sound Stewardship Foundation.

It’s tradition to honor the past year’s human achievements. From peacemakers and scientists to athletes and artists, we celebrate those who inspire us. But what about the wildlife who surround us who make up the biodiversity that sustains us? Each year standout members of those populations also set records and push boundaries, many with lasting results.

Consider P-22, also known as the “Hollywood cat.” In 2012 this young mountain lion surprised biologists and captured hearts by establishing a decade-long residency in the Griffith Park area of Los Angeles. Stealthily threading through backyards and freeways, he demonstrated the value of landscape connectivity, even in urban areas. And though he died in 2022, he inspired a massive fundraising campaign that helped build the largest wildlife bridge in the United States, to be completed in 2025 over California’s 10-lane Highway 101. In this way he changed the world.

RESCHEDULED: Mudchasers wanted: Sign up to track pollution and sediment pumps

Chris Irwin

KNOXVILLE — Join Chris Irwin and others to learn how to help track the origin of sediments and other pollutants in area waterways.

The meeting was postponed by snow and is now set for 7 p.m. Jan. 24 at Barleys, 200 East Jackson Ave., Knoxville.

“Spring is coming and with it rain and mud into the creeks and streams around Knoxville. We think a handful of people working together can stop a lot of mud going into the Tennessee River.

“This meeting is to show maps, a free app for gps pics, and a process to follow mud to its source so we can rat out the developers and others being sloppy with the health of our streams. We have the technology.”

Learn how the Arctic still thrives in the face of existential climate threats in new IMAX film

Doug Strickland is a writer for the Tennessee Aquarium.

CHATTANOOGA — At first glance, the Arctic seems an impossibly inhospitable place, a frigid wasteland of extremes in which nothing can survive.

Only one-quarter of this vast polar region at the top of the world is made up of land. The rest is comprised of a glacially cold ocean capped by vast stretches of ice. 

Despite its harsh conditions, life has found a way to endure — and even thrive — in the Arctic. Audiences will meet just a few of the Arctic’s charismatic residents on Jan. 11, 2024 when the Tennessee Aquarium IMAX 3D Theater debuts a new giant-screen film, Arctic 3D: Our Frozen Planet

Come join staff from Knoxville nonprofit Conservation Fisheries Inc. to learn about CFI's mission to prevent the extinction of rare fish species, and to work for their long-term recovery. We will be discussing some of our successes in fish recovery efforts over the past 37 years, including species found in Great Smoky Mountains National Park.”

MORRISTOWNCarl Williams, a Tennessee Wildlife Resources Agency fisheries technician and self-taught crayfish biologist retired after dedicating more than four decades to wildlife and fisheries conservation and management. 

Williams began working with TWRA in August 1979 through the Young Adult Conservation Corp (YACC), which was a federally funded program. Initially hired for a one-year assignment, he worked with lands management wildlife biologists on various projects, including white-tailed deer and wild turkey restoration. 

The subsequent year marked a shift as he joined TWRA’s Fisheries Division, conducting creel surveys on Cherokee and Douglas reservoirs. In August 1981, he transitioned to the Buffalo Springs Trout Hatchery spending the next seven years propagating and rearing rainbow, brown, brook, lake and Ohrid trout, and distributing them throughout many streams, rivers and reservoirs in East Tennessee.

By providing both mitigation and adaption, dam removal can lower greenhouse gas emissions and restore carbon sinks.

This article was originally published in The Revelator. Gary Wockner is an environmental activist, scientist and writer in Colorado.

As the climate crisis escalates, a huge amount of attention and money is being focused on climate solutions.

These can be divided into two categories: solutions that pursue “mitigation,” which lowers greenhouse gas emissions, and those that pursue methods to adapt to climate impacts to increase human and ecological resiliency.

Dams, of course, create enormous environmental harms, many of which have already been described in scientific literature. Equally well documented is the fact that removing dams can restore seriously damaged ecosystems. But missing from almost every climate-solution story and study is how dam removal can be key for both mitigation and adaptation.

Here are 10 reasons how dam removal fights climate change.
