The Blue Ridge Newsletter for The Nature Foundation at Wintergreen | Vol. 22 Issue 1 | Winter/Spring 2015 From the Director: The History of the Wintergreen Community Whenever one teams up with Don Faulkner, Frank Louthan, L.F. Payne, George Nicklas, Pete Farley and the rest of Wintergreen’s innovative visionaries, the stories of Wintergreen’s beginnings come alive against a backdrop of what often seemed insurmountable obstacles. In a time of great economic instability in the early 1970s with oil embargos, runaway inflation, record high interest rates and financial institution flight, one is amazed at the ingenuity, passion and entrepreneurial agony that lead to the point of “no turning back”. While the historical facts speak for themselves, it is the personal stories that draw us in and we realize we are the benefactors of those struggles some 40 odd years later. It is these stories that intrigued author Mary Buford Hitz’s to take on Wintergreen’s history as a challenge she could easily rise to. Currently, at the end of chapter seven, it seems fitting that she, another passionate, ingenious personality, has come forward to put the story to print. What makes the “fit” more personal is that through Mary Buford Hitz’s Richmond roots she knew most of the key players that made Wintergreen happen. Many individuals have contributed to the success of this project and interviews continue to show up from early property owners as well as employees from those time periods. An impressive set of archives has been formed; written interviews are still welcome. You may submit them to The Nature Foundation by calling 434-325-8169 or by sending an e-mail to [email protected]. The publication date is November 1, 2015. This year’s Winter Lecture Series will be devoted to this exciting event. Meet the founders and hear the stories for yourself! See our calendar for January 17th and February 13th, 2015.

I spent it living and working at the Nature Foundation as an Environmental Educator. Through the WILD programs I was able to educate participants about the Blue Ridge Mountains. I now educate my 4th grade students on everything from ecosystems to lines of latitude. After leaving the Nature Foundation, I jumped into my last year of college at Southeast Missouri State University. In May I graduated with a degree in Elementary Education and an emphasis in Science. My passion for education continues inside my 4th grade classroom where I teach science and social studies. I work at a small school in a small town in Missouri. Everyday my students and I learn and grow together. I am happy to be where I am today. I owe thanks to the Nature Foundation for the experiences that helped me become the educator I am today.

After several years of trial and error, failure and success, the native plant program will be offering native azaleas for sale in the spring of 2015. Early azalea or rose azalea (Rhododendron prinophyllum (Small) Millais) is a 6-12 ft. tall and wide, multistemmed shrub, with airy, ascending branching. It has funnel-shaped, light pink or purplish flowers with protruding stamens in large clusters, appearing before or with the leaves. This azalea is extremely hardy with tolerance to high pH. You have probably seen it or a very similar species, the pinkster azalea blooming in the spring in the woods at Wintergreen or in front of the Trillium House, where there are a few. Our efforts for getting these azaleas to market provide insight into the challenges inherent in propagating native plants by a volunteer group such as ours. Most basic among these is understanding the particular requirements for successfully propagating each species, whether from seed or stem cuttings. We have tried propagating two species of azalea, early (or rose), and flame (Rhododendron calendulaceum (Michx.) Torr.) azalea, using three methods of propagation. Stem (woody) cuttings have been unsuccessful. Taking root cuttings was limitedly successful, but is not a preferred alternative as it can be injurious to the parent plant. Seed propagation has turned out to be the best technique for us. Early attempts were unsuccessful, probably because we collected seed too early. However, since 2012 (early azalea) and 2013 (flame azalea) we have enjoyed a high rate of germination with both species. Succeeding in germinating seeds or rooting stem cuttings meets the first challenge for our group. However, growing them all to maturity has required research mixed with trial and error and a lot of time and effort. In the case of the azaleas, a hummus and acid loving species, we have added bark mulch to potting soils and maintained the pots on one of 3 Continued on next page our greenhouse growing tables outfitted with timed watering cycles. Happily, we now have over 100 early azalea plants in small pots inside the greenhouse waiting to be transplanted into larger pots for eventual sale, and more than 50 outside the greenhouse where they will overwinter in three-gallon pots and be ready for transplanting into a wide variety of landscapes next spring. We hope the flame azaleas will follow close behind. The azaleas are a great addition to our inventory. Marketing these wonderful plants presents another challenge for our group, as does marketing most plants we propagate to a public that is not always aware of their beauty and usefulness. Increased mention in the media about the importance of native plants in sustaining important bird and insect populations has helped, as has the Native Plant webpage on www.twnf.org. Each species we grow is pictured there and a description of the plant’s attributes, appearance and garden uses is included. Check the website for more information about azaleas. While we do not claim to be landscape designers, we have developed expertise and an extensive knowledge-base about our native plants which we are happy to share. The native azaleas, for example, are most often found naturally in wooded, north-facing slopes and wooded ravines and along streams. Their flowers are attractive to butterflies and hummingbirds and they serve well in a landscape plan as an understory tree or shrub on the edge of the woods surrounded by various herbaceous plants and ferns. Yet another challenge for our group is maintaining an ever expanding inventory. First, successive transplanting to accommodate and encourage growth takes hours and hours of work. Then, we have to make space for the additional larger pots. The space required just for our fifty or more three-gallon azalea pots covers several square feet. Adding those to the other 15 or so species in threefive gallon pots has required us to expand our nursery space to accommodate shrubs and small trees. To meet this challenge, in 2014 we expanded the useable portions of our greenhouse and its grounds. Volunteers worked hard mulching areas, creating paths, setting up watering systems and generally improving the appearance around the greenhouse. The resulting space easily accommodates our maturing and expanding selection of shrubs and small trees. Inside the greenhouse, we have expanded our space to house more herbaceous plants, grasses and ferns, as well as newly taken cuttings and young plants. 2015 promises to be a year with a large and varied inventory. In addition to the early azaleas, we will have for the first time young sourwood trees (a large ornamental tree with showy white sprays of flowers in the summer and brilliant red leaves in fall). Standards such as ninebark, spirea, and mountain laurel will continue to be available. We are working hard to replenish our supply of the herbaceous plants, some of which we sold out of this year, and will have ample supplies available for spring 2015. We thank our loyal volunteers and patrons for making the program a success and look forward to seeing you in the spring. 4 This is Not Supposed to Happen by Josh Palumbo The emerald ash borer (EAB), an exotic insect invader introduced to Virginia in 2004, was said to be dependent on just one tree species, ash (Fraxinus spp), for its survival. For some states such as Ohio and Pennsylvania, ash is a dominant tree of the landscape. Ash is not a major component of the Virginia forest so this insect has not created quite the frenzy in our area compared to our northeast neighbors. Oh, how things change in the blink of an eye. This past August, EAB was found hosting in our beloved fringetree (Chionanthus virginics), a relative of ash. A Wright State biology professor, acting on a hunch, began inspecting fringetree plantings around his town and came upon the classic D-shaped exit holes EAB Adult characteristic of this borer. After taking the larvae back to the lab for study it was determined, based on the larvae morphology, to be emerald ash borer. Wait, this is not supposed to happen. The national EAB information website clearly states, “It only attacks ash trees”. I can only assume the EAB has not been reading its own press clippings. Every scientific publication concerning EAB is clear to ensure that it is host specific. This leaves us with two clear possibilities as to why EAB was found using fringetree in its lifecycle. The first is that it has a much wider host range than originally thought. The second is that it has adapted to use different hosts than ash. Both possibilities open up the forests of Virginia to a great deal of uncertainty. Will EAB continue to find new host species compatible to its lifecycle? Will these species be pivotal parts of our ecology? How does this impact the Wintergreen property owner? Truthfully, emerald ash borer hosting in fringetree, in addition to ash trees, has a minor effect on the forest ecology when compared to “game changers” such as chestnut blight. It affects us more on a landscape level. Fringetree is a great landscape offering that our Plant Propagation Team is beginning to grow for its wonderful landscape qualities such a stature and gorgeous white spring flowers. If EAB shows a propensity to fringetree across its current range, fringetree may be cut out of propagation plans and nursery sales indefinitely. Despite this adaptation, there is hope present in our ecosystem. Gypsy moth was once defoliating hundreds of thousands of acres of Virginia forest per year. Now due to the presence of a control mechanism, Entomophaga maimaiga, gypsy moth is but a whisper compared to its once wild fury. My hope is that as emerald ash borer adapts to our ecosystem a control mechanism is out there waiting to suppress this storm spreading through Virginia. 5 Tall Tails and Wild Cats of Virginia by Peggy Hash Within many parts of the Blue Ridge, conversation over the presence or absence of a particular species—mainly the “panther” or “mountain lion”—can turn into surprisingly passionate, albeit confusing, debate. Our part of rural Appalachia is likely one such area. The Virginia Department of Game and Inland Fisheries lists Nelson County, along with Shenandoah National Park, Bedford County, and Amherst County, as a point of origin for most of Virginia’s reported, but unconfirmed sightings of America’s biggest cat. What exactly is this animal? What is its proper name? The animal is Felis concolor, meaning “cat of one color” but what the animal lacks in coloration, it makes up for in names! It is called mountain lion, cougar, puma, panther, “painter” and catamount. Which words are used and understood depends on the individual. Any one of these words can conjure up a menagerie of fuzzy mental images, depicting multiple variations on the feline theme—a creature with elliptical pupils, pointy ears, pointier teeth, and retractable claws… with or without a long tail, colors or stripes. Because these animals are so rarely spotted even where they are known to be present, very few people can lay a definite claim to seeing one in the wild. Thus, these hazy mental pictures tend to be fusions of several members of the cat family, assembled by the imagination’s influence on memories garnered from television and computer screens, magazines, books and conversation. No wonder these conversations can be confusing. Let’s take a look at the real wildcats of North America (and one of South America and Central America) so we can better present the evidence (and lack thereof) regarding their presence in Virginia. We’ll start at the center of the controversy, with Felis concolor. It is sandy overall, with a pale belly, blacktipped tail and a sooty-looking muzzle. Its tail is very long. Kittens have spots, but adults are plain overall. Weighing between 100 to 200 pounds, with a three to six foot body and a tail extending another two feet or more, it is the largest cat in the country. For the first half of our country’s history, it lived here in Virginia. Livestock owners, by all confirmed accounts, eradicated it in this state before the 20th century was underway. The last confirmed wild mountain lion documented in this state was likely indeed the last. It was killed in Washington County in 1882. Since then, the only word of truly wild mountain lions in Virginia is verified by just that—word, with none being official. Nonetheless, the Virginia Department of Game and Inland Fisheries lists 121 unconfirmed reports since 1970 and names Nelson County as a hotspot. That makes one wonder…what did those 121 people see? When imagination, misinformation, and memory collide, they create what forensic psychologists call “recall bias”, which is simply an error in how experiences are remembered. Richard Wise, forensic psychologist at the University of North Dakota explains, “When an eyewitness recalls a crime, he or she must reconstruct his or her memory of the crime. …To fill in gaps in memory, the eyewitness relies upon his or her expectation, attitudes, prejudices, bias, and prior knowledge.” Harley Shaw, former mountain lion biologist for Arizona’s Department of Fish and Wildlife explains it this way, “After years of chasing UFOs (unidentified furry objects) I now discount out of hand any sightings of lions, even from professional biologists. The human mind is a strange and wonderful thing, and it’s totally unreliable.” Though no American wildcat has 6 Continued on next page ever been spotted committing grand-theft auto (or piloting a spaceship) an unexpected wildlife sighting can make your heart beat fast. Combine an instant’s experience with the effects of time, distance, darkness, brightness and paging through a stack of field guides three days later and you can see how even informed minds can be subject to recall bias. Multiply that bias when misinformation comes into play, which may explain why up to one in four people who report big cats to the Virginia Department of Game and Inland Fisheries describe large black cats, often referred to as “panthers”. Panthers do live in North America, however, and on the east coast for that matter! The Florida Panther is a subspecies of Felis concolor. It is critically endangered and less than 100 survive in that state. But none of these so-called “panthers” are black. They look like western mountain lions, as pictured above. Regardless, the word “panther” prompts the mental image of a black cat and may apply itself to any dark creature…or one seen in bad lighting. The closest real black panthers, by the way, exist in South and Central America and are better known as jaguars, or, scientifically, Panthera onca. The dark fur is simply a genetic variation and one litter may contain kittens with spots and black kittens. The two other wild cats that come into question are much harder to distinguish from each other than from the mountain lion. These are Lynx rufus and Lynx canadensis, or simply the North American bobcat and Canadian lynx. They’re so alike they can interbreed but the bobcat is more widespread in the United States and is the only confirmed wildcat in Virginia. The bobcat and Canadian lynx are about the same size and weight, 2 to 3.5 feet long and only 10-25 pounds. Both have blacktufted ears, although the bobcat’s are shorter. A This bobcat was photographed at Wintergreen via one bobcat’s back legs are only slightly longer than its front legs, a difference that is more extreme in of our trail cameras! the Canadian lynx. Bobcats also have a slightly longer (but still short!) tail than the Canadian lynx. If you’ve managed to obtain a good enough look to discern these differences on either cat, chances are you won’t be confusing it for the long-tailed mountain lion that weighs up to 200 pounds! Misidentifications of bears, coyotes, German shepherds and even house cats are common as well. Although, seeing a mountain lion in Virginia isn’t impossible. Michael Fies, of the Virginia Department of Game and Inland Fisheries, found an escaped captive under his porch about twenty years ago, in Augusta County. A second mountain lion, which had escaped from the same private owner, infiltrated a turkey farm the next day. Legally or otherwise, people do keep mountain lions and other creatures throughout the country so escaped captives present the most likely scenario for an actual sighting. This Canadian Lynx was photographed in the Rocky Mountains. See how long its back legs are? Whether the mountain lion will return to its historical range remains to be seen, but should you be there to take the photo, please submit it to The Nature Foundation at Wintergreen first! 7 Woolly Bear Winters and Other Weather Myths by Peggy Hash For over 2,000 years, humans have tried just about everything in an attempt to predict the weather. Ancient Babylonian cloud-watchers, Chinese astrologers, Ptolemy, Aristotle, his Middle-Eastern counterpart Al-Kindi, the Renaissance men and current experts have applied observation, hypothesis, alchemy, magic and technology to this pursuit. Yet, ancient alchemists and modern meteorologists agree on one point—predicting the weather is not an exact science! Current advancements would have astonished the old world: balloons that enter the stratosphere, chance of rain narrowed down to a percent on a clear day, satellites next to the stars once aligned with gods and of course— Twitter! Yet even now, lining up the sunny/rainy/partly cloudy icons on your forecast platform of choice can feel less like planning a hike or a road trip and more like playing the lottery. No wonder some folks consult nature, a source older than civilization, which seems to know what it is doing most of the time. This approach may create folklore, which can carry a “grain-of truth” or be better taken with a “grain of salt”. Thus, folklore persists if not for scientific merit, then for entertainment value. Or a blend of both! The Woolly Bear Caterpillar: Mostly Fun “Woolly bear caterpillars forecast winter weather.” The 13 rows of fur on the woolly bear caterpillar’s back represent 13 weeks of winter, with the black rows predicting cold periods and the brown rows corresponding to milder weeks. Likewise, extra furry caterpillars preview blizzards while straggly worms indicate less reason to invest in snow tires. Furthermore, a north-heading woolly worm is said to suggest a milder winter than a southheading one. This predictor is more fun than fact, but it is one of the few Old Farmer’s Almanac sayings that garnered some research, although that too may have been for sport. In 1948, Curator of Insects at the Museum of Natural History in New York City, Dr. C. H. Curran recruited his wife, a reporter from The New York Herald Tribune and a number of other friends to look into this idea. They dubbed themselves “The Original Society of the Friends of the Woolly Bear” and gathered as many caterpillars as they could in one day for the next eight years then compared their markings to real weather data. Curran’s brownish woolly bears correlate to milder winters during that period, but even Curran was skeptical of his small sample sizes. However, a woolly bear-to-weather link may still have some relevance. Though some species are naturally darker woolly bears do tend to turn brown as they age, providing a clue as to how early they broke from hibernation. This, of course, would indicate the severity of the previous year’s winter. Tailspin: Grain of Truth This one takes the form of a limerick: Tail’s pointing west, Weather’s at its best Tail’s point east, Weather’s at its least The rhyme refers to horses and cattle, claiming that the orientation of the animal’s tail indicates the quality of oncoming weather. The idea may not be quite as ludicrous as it sounds at first, since these grazers prefer not to 8 Continued on next page stand with the wind in their faces, and easterly winds are more likely to bring storms. Storms: 50% Chance of Truth These sayings are more of a reach, but they’re hard to argue with since the animals may demonstrate these behaviors at any time. - - - - - Pigs carry sticks before a storm Dogs eat grass before a storm Cows follow bulls to pasture (instead of vice-versa) before a storm Crows, well, crow before a storm Roosters call before a storm Note: The Yellow-billed Cuckoo lives up to its nickname “Rain Crow”. Although not a crow, this normally secretive bird will call in response to loud noises, including thunder. Lighting Never Strikes the Same Place Twice?: Don’t Count On It! Ironically, the most oft-repeated myths can have the least basis in fact. Lightening can definitely strike the same place twice and some locations and structures are especially prone. The Empire State Building, for example, is struck about 25 times per year! Froggy Weather: False “Frogs singing in the evening indicate fair weather for the next day.” To be “fair”, this one might ring true for frogs. As amphibians who breathe partially through their skin, frogs are more active in wet, humid weather…which humans don’t generally find as favorable! Of Lions and Lambs: True “March comes in like a lion and out like a lamb” is the unofficial slogan of March. Of obvious significance is the fact that March starts out cold and fierce (like a lion), then shifts to milder temperatures (like a lamb) later in the month. Also, in the northern hemisphere, the constellation Leo is more visible in early March. Leo represents the lion, who was slain by Hercules in Greek mythology. Later in the month the constellation of Aries is easier to see. In Greek mythology, Aries was a ram whose fleece was sought by another hero, Jason of the Argonauts. So, “weather” (again, pun intended) these predictions are foreshadowing or just for fun, test them out or invent your own! But either way, pack a raincoat, in case you find yourself relating to the following poem: Ode To the Weatherman “And in the dying embers These are my main regrets: When I’m right no one remembers; When I’m wrong no one forgets.” - Anonymous 9 KID’S NOOK Our Resident Feathered Friends With winter upon us, most birds have migrated to Central and South America while most amphibians, reptiles, and mammals are deep asleep in their burrows. But winter wildlife watching is still underway! In fact, now that bears are spending most of their time in semi-hibernation, December 1st through April 1st is the time to hang birdfeeders (which, unfortunately, may accidentally become “bear-feeders” during the rest of the year). So now is the time to get to know your feathered feeder favorites, from the warmth of your house or on a nature walk. Whether you stay in or bundle up for an outside adventure, be on the lookout for these year-round residents! American Goldfinch Maybe you recognized these beauties in the summer by their black caps and bright lemon yellow color. Their colors fade in the winter but they still have an appetite for sunflower seeds and thistle. Red-bellied Woodpecker Somebody should probably think of a better name for the Redbellied Woodpecker. Even up-close, you can barely see the red on their bellies. Females don’t have as much red on their heads, but these birds still provide a welcome splash of color on winter days! Downy Woodpecker These are the smallest woodpeckers, and the ones you’re most likely to see…but pay close attention to its beak. If it seems a lot longer than this one’s, it’s probably a Hairy Woodpecker! 10 Continued on next page KID’S NOOK Carolina Chickadee Admire these birds in practically all kinds of weather! Whether it’s rainy, snowy, or freezing they’ll forage for food all day long. Northern Cardinal Don’t forget Virginia’s state bird! Males stay bright red all year; this cardinal is female. Though she is not as brightly colored, female cardinals are among the few female birds that sing. Dark-eyed Junco These birds gather by the dozens to feed off the ground. Some have red eyes. When they fly, watch for the quick flashes of white you’ll see on the sides of their tail. Also, look at your field guide and out your window for Mourning Doves, Blue Jays, Purple Finches, House Finches, Pileated Woodpeckers, Yellow-bellied Sapsuckers, Northern Flickers, and more! 11
