WALLAND — The University of Tennessee Institute of Agriculture will host a demonstration of its new robotic milking technology at the UT AgResearch and Education Center’s Little River Unit in Blount County. The new system, developed by the Lely Corporation in the Netherlands, allows for the cows to be automatically milked at their own will in a stress-free environment. The demonstration is set for 10 a.m. May 2 and will include remarks from prominent university and community leaders.

The cows are trained to walk up to the robotic system, where each animal will be recognized by a sensor on its collar. The system then knows how much feed to give the cow while she’s being milked, based on historical data. The cow is free to eat, drink and rest while being milked, and in an area where there’s less cattle traffic. About 120 dairy cows can be milked and individual records kept through two robotic systems in a relatively short amount of time.

“The mission of UT AgResearch is to conduct leading-edge projects to serve the evolving needs of the agriculture and forestry industry in Tennessee and beyond,” said Hongwei Xin, dean of UT AgResearch.

“The introduction of milking robots into our existing traditional dairy production system at the Little River dairy facility allows our researchers to find answers to questions ranging from interactions between the animals and robots, impact on the animal’s production performance, and labor savings and profitability. The robotic milking system is part of the UT Precision Livestock Farming (PLF) initiative that aims to improve production efficiency and food supply chain robustness through enhanced animal welfare. UTIA is poised to be the leader in PLF in the region, the nation and the world.”

Got sprawl? It’s past time to help young farmers access land

I’m not a farmer, I’m a hiker. I live in a shady mountain gap and can’t grow a fully ripe tomato in the summer — not to mention that the half-acre parcel of land that I call home includes a significant portion of river bed. But as a 20-year resident of rural Blount County, a gateway to Great Smoky Mountains National Park, I’ve watched the steady disappearance of farms over time, and I have wondered what can be done. 

This is why I rose at 4 a.m. for a trip to Nashville, planning to arrive before my alarm would normally sound. It will be my first time lobbying the state legislature and my first time meeting in person with the organizers of the Southeast Tennessee chapter of the National Young Farmers Coalition — known as “Young Farmers” — who I’ve been Zooming with for the better part of the year. We are all headed to Ag Day on the Hill to advocate for young and beginning farmers and the  preservation of farmland for future generations. 

The big brown bat feeds on beetles, flies, moths, and true bugs, which it catches and eats while in flight. It is widespread across the Southern Appalachians and forages for food by flying slow, straight courses over water, forest canopies, wooded clearings, and around city lights.  J.

North America’s first State of the Bats report gives a sobering outlook for the winged mammals. According to the North American Bat Conservation Alliance report:

• More than half of the 154 known bat species on the continent could face severe population declines over the next 15 years.
• During that time, up to 82 percent of bat species will be negatively affected by climate change, especially extreme drought and temperatures.
• The scope and severity of threats — including habitat loss, wind turbines and the deadly bat disease white-nose syndrome — are increasing.

The news isn’t all bad. The report outlines ways to help and emphasizes the wide-ranging benefits of bats, from improving crop yields to eating insect pests. It also highlights the promise of focused, collaborative conservation efforts.

Case in point, the lesser long-nosed bat was once endangered in Mexico and the U.S. But thanks to international efforts, it is now delisted and recovered in both countries.

The North American Bat Conservation Alliance is another example. The coalition involving the U.S., Mexico and Canada created the 2023 State of the Bats report with Bat Conservation International and others.

“Bats face many challenges and the conservation landscape is increasingly complex,” said Dr. Jeremy Coleman, alliance co-chair and white-nose syndrome coordinator for the U.S. Fish and Wildlife Service. “While there is more to do, the level of international collaboration we have achieved for bat conservation in North America is a bright spot and a cause for optimism going forward.”

This photo of the Southern Appalachians was taken from 30,000 feet. “Notice how the clouds are parallel with the ridges below them. Wind near the surface blowing up the western slopes forms waves in the atmosphere. At the crest of the wave, over the ridge tops, the air has cooled sufficiently to condense into clouds. As this air descends toward the wave trough, it becomes slightly warmer and drier, inhibiting condensation.”  Seth Adams via NASA

Earth Day activities have cooled in Knoxville over the decades. The planet has not.

KNOXVILLE — It’s been 52 years since the modern environmental movement was born on what is now known around the world as Earth Day.

Now reckoned to be the world’s largest secular observance, Earth Day is the climax of Earth Week (April 16 to 22), which brings together an estimated billion people around the globe working to change human behavior and push for pro-environment economic and legislative action. This year’s theme is “Invest in the planet.”

Events marking Earth Day in Knoxville tend to vary in size and tone from year-to-year, with 2023 providing environmentally minded residents with a number of ways to celebrate Mother Earth. 

Perhaps the most memorable of those years was the very first one, when one of the most important voices in the burgeoning environmental movement spoke on the University of Tennessee campus.

Jane Jacobs, who is now recognized as “the godmother of the New Urbanism movement,” gave a lecture to a crowd of nearly 200 people on the topic of “Man and His Environment” at the Alumni Memorial Hall, according to Jack Neely, who heads the Knoxville History Project.

‘It’s very good for the soul.’ Bo Baxter and Conservation Fisheries focus underwater to save our Southern fishes.

This is the latest installment of an occasional series, Hellbent, profiling citizens and organizations who work to preserve and improve the Southern Appalachian environment.

KNOXVILLE — For more than 35 years, an obscure nonprofit headquartered here has grown into one of the most quietly successful champions of ecology and environmental restoration in the Eastern United States.

Conservation Fisheries, which occupies a 5,000-square foot facility near the Pellissippi State University campus on Division Street, has spent nearly four decades restoring native fish populations to numerous waterways damaged years ago by misguided governmental policies. 

In fact, the mid-20th century saw wildlife officials frequently exterminating key aquatic species to make way for game fish like trout.

“It was bad science, but it was the best they had at the time,” said Conservation Fisheries Executive Director Bo Baxter. “A lot of the central concepts of ecology, like food webs and communities, were not developed back then.”
