Despite their enormous ecological values, new research reveals we don’t understand how most arachnid species are faring right now — or do much to protect them.

Spiders need our help, and we may need to overcome our biases and fears to make that happen.

“The feeling that people have towards spiders is not unique,” says Marco Isaia, an arachnologist and associate professor at the University of Turin in Italy. “Nightmares, anxieties and fears are very frequent reactions in ‘normal’ people,” he concedes.

Cerulean Art

Ephemeral birds of lasting beauty dependent on Tennessee forest

Think azure. A male cerulean warbler is sky blue. And to see one, you have to climb to the tops of certain Appalachian ridges and look toward the wild blue. To see one is to see a bit of heaven in an eight-gram bird.

East Tennessee’s Royal Blue Unit is not named in honor of the cerulean warbler but it’s appropriate to think so. The land parcel is part of the North Cumberland Wildlife Management Area and is one of the few places — very few places — the sky-blue passerines still nest in North America. It is estimated that 80 percent of the remaining population nests in the Appalachians. 

The cerulean is the fastest declining migratory songbird in North America, said ornithologist David Aborn, an assistant professor of biology, geology and environmental science at UT Chattanooga. The Breeding Bird Survey estimates that cerulean warbler population declined by 70 percent between 1966 and 2008.

“The species is not in danger of imminent extinction, but is rare enough to warrant concern, and its future is not assured,” the U.S. Fish and Wildlife Service reported in 2020.

Currently a management goal of “no net loss” is in place. “Management programs can be instituted at the present time that do not require major changes in land-use practices, but do consider silviculture appropriate to producing habitat for the species,” the report concluded.

The American Bird Conservancy and ProAves Colombia purchased 500 acres of rural land identified as wintering sites for the migratory bird. The Cerulean Warbler Reserve is the first in Latin America set aside for a migrant bird. It’s a start. But the beautiful bird faces many challenges here and abroad.

Park service postpones 175-acre controlled burn

Citing low humidity and dry conditions, park officials postponed the planned burn until at least Tuesday along the park boundary in Wears Valley in the Metcalf Bottoms area. Another burn is planned near Sparks Lane in Cades Cove later in the week, depending on weather conditions.

The original story is below:

Park managers plan a controlled burn along the park boundary in Wears Cove starting Monday. Don’t freak if you see heavy smoke in the area. March is an opportune time to conduct controlled burns for hazardous debris removal and habitat improvement in the interface between rural habitation and protected natural areas.

Fire prevention practices have become more widespread in Great Smoky Mountains National Park since a devastating and deadly November 2016 wildfire that spread into populated areas of Gatlinburg and Sevier County.

Here’s the straight skinny from the park service, per a release:

“Great Smoky Mountains National Park and the Appalachian-Piedmont-Coastal Zone fire management staff plan to conduct a 175-acre prescribed burn along the park boundary in Wears Valley to the Metcalf Bottoms Picnic Area.  The burn will take place between Monday, March 8 through Thursday, March 11, depending on weather. Prescribed burn operations are expected to take two days.  

A National Park Service (NPS) crew of wildland fire specialists will conduct the prescribed burn to reduce the amount of flammable brush along the park’s boundary with residential homes. This unit was burned successfully in 2009 and is part of a multi-year plan to reduce flammable materials along the park boundary with residential areas.  

“A long-term goal of this project is to maintain fire and drought tolerant trees like oak and pine on upper slopes and ridges in the park,” said Fire Ecologist Rob Klein. “Open woodlands of oak and pine provide habitat for a diverse set of plants and animals, and the health of these sites benefits from frequent, low-intensity burning.”

This picture of a cicada, sitting on a hand, shows that its length from the head to the tips of its transparent wings, stretched back in their resting position, is about the width of two fingers
 

After 17-year wait, millions of cicadas are coming

“Do not go gentle into that good night, Old age should burn and rave at the close of day; Rage, rage against the dying of the light." — Dylan Thomas

Imagine living 99.99 percent of your life underground largely unseen and then emerging above the earth for one last grand gesture of panache and reproduction and death.

This year it’s time for the 17-year cicada Brood X to pop up. The last time they appeared in Knox County was 2004. Periodical cicadas are related to the more frequently seen and heard Dog Day cicadas or harvestflies that appear every July.

Periodical cicadas remain subterranean for years. Here in the Tennessee Valley, we actually have two populations that overlap. Brood X, known as “the big brood” that will be seen and heard this summer, emerges every 17 years. Brood XIX climbs from the ground every 13 years, and is not scheduled to reappear in the valley until 2024.

Annual cicadas look like large green flies. Periodical cicadas are more colorful: bluish with red eyes and gold wings. Both groups are in the insect order Hemiptera and spend their larval stage underground tapping into tree roots for nourishment.

At this moment, this year’s brood is inching its way upward. The cicadas lie in wait below the surface until the right conditions — day length and temperature — signal it’s time to move out. If you happen to be in an area where the cicadas are, you’ll see hundreds, maybe thousands, all over the place. It’s truly one of nature’s most spectacular occurrences.

They usually begin to climb from the ground at dusk in early May and quickly scurry to a nearby tall object that they climb and shed their last larval skin. After their wings dry, the new adults leave behind the husk of their former life and fly away. For the next few weeks, the males buzz to attract the females. After they mate, the females lay eggs in tender branches. All the adults die in a few weeks; when the eggs hatch the tiny larva crawl to the ground to disappear for another 17 years.

New River Gorge National Park preserves paddling and climbing paradise

When you think of national parks within a day’s drive of East Tennessee, what comes to mind? Great Smoky Mountains National Park, of course. Or perhaps Mammoth Cave in Kentucky, or Virginia’s Shenandoah. You have a new option.        

New River Gorge National Park and Preserve, created by Congress Dec. 27, 2020, by way of a pandemic relief bill, is America’s 63rd and newest national park. Located in southern West Virginia, the 72,186-acre park and preserve protects land along both sides of a 53-mile stretch of the New River, which is famous for its world-class whitewater. It’s walls rise up to 1,400 feet, attracting rock climbers from across the country.

The New River Gorge, known locally as “The New,” currently welcomes about 1.4 million visitors a year. It’s within a day’s drive of 40 percent of the U.S. population, and is expecting an initial 20 percent increase in visitation this year because it is now a national park with national attention.

Local merchants and business owners are already touting the economic benefits, including new jobs in in-store retail and dining, two industries decimated by the Covid-19 pandemic.

“We’re super excited about it,” Cathedral Cafe manager Cassidy Bays said. She said the cafe, just minutes from the park, plans to increase staff and extend hours. “We’re even building an outdoor patio to increase dining space,” Bays said.

And this is not your grandfather’s West Virginia: Locavores can find locally sourced food and lean into a vegan juice bar. Several community-supported agriculture (CSA) and co-op farms are a main source of the cafe menu. “We actually cater to locavores. We are a farm-to-table restaurant” Bays said.

Counting birds and taking names at Seven Islands

Dozens join annual avian survey at Seven Islands State Birding Park

KODAK, TN — State park interpretive ranger Clare Dattilo led the group slowly but surely across the muddy winter landscape of Seven Islands State Birding Park, taking note of birdsong and investigating undulating flashes of quick color against the backdrop of green cedars and nude tree branches and grasses flattened by the weight of a recent snow.

Even in the dead of winter, woods and fields are filled with life.

The birding park hosted both trained ornithologists and casual birdwatchers to scope out species to include in the annual Audubon Society Christmas bird count. Dattilo was tallying her numbers with a couple of journalists and a long-time friend from college.

Bluff Mountain loomed to the east. The crest of the Smokies, in commanding view on clear days, was shrouded in freezing fog. Ring-billed seagulls flew high overhead while a couple of Carolina wrens chirped in the underbrush.

Bursts of bluebirds and cardinals yielded glimpses of color. Flycatchers and downy woodpeckers concentrated on their rhythmic work amidst the barren winter branches of the huge oaks, hickories and maples that spread across the ridges of the park and into its small hollows. White-tailed deer browsed silently, undeterred and seemingly and correctly unbothered by the birdwatchers.

Still no glimpses of the ghost bird

‘Lord God Bird’ of lore, a sad reminder of what we have lost

We stood agape. Before us, on a white countertop as big as a ping pong table, lay 17 dead ivory-billed woodpeckers. They were museum specimens neatly arranged in two groups: nine males and eight females, all lined up like ears of corn in separate wooden trays. Each had a paper label attached to a leg with handwritten notation of when and where it had been collected; most seemed to date from the late 1800s. Being in the presence of so many rendered us reverently speechless.

Crazy monkey love or amorous owls?

Written by

February kicks off the season of love for region’s barred owls

The frosty woods may be relatively quiet today, but soon the hilltops and hollers will echo with deep, resonant voices.

Barred owls (Strix varia) are our second-largest resident owl here in the Southeast, second only to the great horned owl (Bubo virginianus).  With their fluffier plumage, doe-eyed countenance and round profiles lacking ear tufts, barred owls don’t have quite the fierce appearance of their more formidable neighbors. They’re also generally easier to observe. Often active in the daytime and fond of low perches, barred owls occasionally make themselves visible to lucky woodland wanderers. More often, though, they are heard rather than seen. Their breeding season may extend into summer, but courtship generally fires up in February and peaks in March. This is my favorite time to seek them out on the woodland slopes, usually near water, that they call home.

Barred owls are not easy to find per se, but they definitely make themselves more conspicuous when looking for love. Their best-known call is an eight-beat hoot often verbalized as “Who cooks for you? Who cooks for y’all?” with the final “y’all” drawn out in a dramatically descending, tremulous wail. They sometimes give the wail alone or as crescendo following a series of ascending hoots.

To hear any of these sounds echoing through a twilight woods can fill one with awe, but they give another vocal performance that is generally only heard when an amorous pair of owls meets up. This call, for lack of a better term, is often referred to simply as the “monkey call.”

A caterwauling cacophony of simian sounds explodes from a dense grove of hemlocks. Have chimpanzees escaped from the local zoo? Nope, just a couple of night birds seeking romance. People who hear these calls without knowing the caller are often understandably perturbed. More than once I’ve been awakened suddenly in my tent when such a liaison takes place in a tree over my campsite, and I can say it’s a bit unsettling, even knowing the avian source.

So when you’re walking in the woods over the next few weeks, keep an eye and an ear out for these lovebirds as they’re at their most vocal. And if you hear what sounds like a troop of monkeys hailing the setting sun, just remember that, more likely than not, you’re just hearing the music of owls in love.

Part I of this three-part series examines how the development of civilizations and rapid population growth gave rise to forest tree domestication. Parts II and III will discuss the role that the University of Tennessee’s Tree Improvement Program has played in forest sustainability by contributing to the productivity and health of Tennessee’s present and future forests.

Wood and lumber figured prominently in ancient civilizations, ranging from everyday use for warmth, cooking, and shelter to specialty uses like veneers for furniture and construction with scented woods. 

No matter what continent or hemisphere, as human civilizations evolved from collections of nomad hunter-gatherers to the steel, brick, glass, and mortar cities of today, the impact on forested land proportionally increased. As villages became towns and, eventually, cities, forests were harvested in an ever-increasing radius around the population centers. Wild animals and plants were also harvested in the same manner, drastically altering ecosystems and causing massive erosion.

Nations that quickly exhausted the best trees in their limited forested lands, like ancient Egypt and Greece, met wood demands for construction or specialty products by importing wood from other nations. The then-rich forests of Lebanon and Cyprus were harvested to export timber to countries suffering from a timber famine.
