Monarchs are one of Vermont’s most recognizable butterflies. Their distinctly patterned orange and black wings are both well known and loved; making them the state butterfly of Vermont, as well as six other states [1]. There are many commonly known facts about monarchs and their fondness for milkweed, but there are also many misconceptions.

One commonly mistaken belief is that monarch butterflies eat solely milkweed. Rather, it is the caterpillars that rely on the milkweed vegetation for food. The butterflies lay their pinhead-sized eggs underneath milkweed leaves as the foliage is the one and only plant that monarch caterpillars will eat. Meanwhile, the adult butterflies are often seen sipping on nectar from a variety of flowers.

Many people also think that if there is milkweed around, then monarchs should then be thriving. Young caterpillars actually have a relatively low survival rate when eating the milkweed, only about 3-11%. About 30% of larval losses are due to the mandibles of the caterpillar getting stuck in the sticky latex glue. Monarch researcher Stephen Malcolm wrote that a caterpillars first bite into the milkweed is “the most dangerous thing the ever do in their life”. However, some caterpillars have developed strategies to protect themselves from the latex. Some will chew through the midvein of the leaf to cut off latex flow to the area they are eating [2]. Every time you see a monarch caterpillar metamorphose, it has beaten the odds of survival.

Another misconception about milkweed is that it is only good for monarchs. In reality, there are actually dozens of other species that feed exclusively on milkweed as well, including many different types of the milkweed beetle, the cycnia moth, and the milkweed tussock moth [2]. There are also many pollinators such as bees and butterflies that use the nectar from milkweed as a food source, this in turn attracts other predators to the plant, which then attracts scavengers, making milkweed a valuable plant that contributes to diverse ecosystems.

It is often assumed that mowing milkweed is harmful to monarchs. However, it is actually the opposite. The chemicals given off by milkweed’s toxic latex glue allow the adult butterflies to help locate the plant and then lay eggs on it. Caterpillars absorb the toxins and become poisonous themselves. When a milkweed plant is cut down, it grows back with an even higher concentration of latex glue, so naturally butterflies tend to prefer milkweed that has been regrown. Here in Burlington, a field off of the bike path, just north of North Beach, is known as monarch meadow. The field is currently being mowed and managed to encourage milkweed regrowth and help provide a breeding area for migrating monarchs.

Stop by the field during the late summer and you might be lucky enough to catch a glimpse of the migrating monarchs!

Newt Tales

Photo by Griffin Dahl, around a dried up vernal pool in Raven Ridge Natural Area.

While hiking below a vast dolostone face within the Raven Ridge Natural Area on the border of Hinesburg, Monkton, and Charlotte, a bright orange figure caught my eye waddling along a patch of leaf litter. The area was most likely a dried up vernal pool, a seasonal breeding pool for amphibians, covered thoroughly with wet leaves, fallen snags and mossy cobble. Captivated by its silent presence and clumsy strides, I was in awe of the fact that I had never notice this gentle forest dweller in the past. This adolescent salamander was an Eastern Newt, a complex amphibian migrating between Vermont’s waterways and the moist crevices of a typical Northern Hardwood Forest.

Breeding

The breeding process for an Eastern Newt begins during early spring, as the egg filled female searches for a mate near potential breeding ponds. The females are attracted to a male’s spots and appealing pheromones that waft through the water as they wiggle their broad tails. Males then drop sperm packets in the water, awaiting the female to pick up these packets with their cloaca, a cavity located at the end of amphibians digestive tract, in order to fertilize her eggs successfully [1]. Finally, a female will lay her eggs one at a time and scatter  them upon aquatic plants, leaving them to survive independently for around a month or two before hatching [2].  

Incubation/ Larval Stage:

These 200 to 400 jelly covered eggs now go through a 2 to 6 week incubation stage before hatching, followed by their larval stage lasting another 2 to 6 months. During this stage larvae are brownish-green and develop gills, growing to about a half inch in length. These larvae feed on small aquatic insects and crustaceans until they leave their birth ponds into the summer, lose their gills and start their first terrestrial stage of life [1].

Eft/ Juvenile Stage:

At last, the larvae develop into their juvenile, terrestrial stage where they are known as Red Efts. Efts use their bright orangish-red coloration to warn predators of their poisonous skin secretions. But don’t fear, handling these creatures is perfectly safe. Red Efts grow up to 5 inches in length and reach sexual maturity around 3 years old [4]. These juvenile efts feed on small invertebrates like snails, springtails and soil mites. Eastern Newts can survive in the eft stage for up to eight years before maturing into their adult stage so long as their habitat is sufficiently moist for survival [3].

Mature Stage:

As efts reach their mature adult stage, their skin darkens reaching a brownish-yellow or green coloration, their tails flatten, and their underbelly brightens to a yellow color with black spots. They now return to aquatic environments, searching for temporary and seasonal habitats anywhere from small lakes to marshes, though mature newts prefer abandoned beaver ponds [4]. Here they feed on immature aquatic insects, larvae and other amphibians breeding in nearby vernal pools, continuing the life cycle of the Eastern Newt for further generations to come [2]. The Eastern Newt is a delicate and often overlooked species found throughout the eastern United States, so remember next time you’re walking in the woods, especially in the rain, keep your eyes peeled for orange flashes under logs and rocks… it might just make your day.

What’s In a Name When It Comes to Moths?

toothed somberwing

National Moth Week has come and gone, but it’s still a great time to get outside and look for moths. Why bother with moths, you ask? Well, they come in a dizzying variety of colors, shapes and sizes, and occupy just about every terrestrial habitat in North America. They have fascinating life cycles and strategies for survival, lurking literally behind every leaf and branch. Many of them come to electric lights at night, so you can sit back, relax, and wait for them to come to you (a plus for fieldwork). But there’s another reason to study moths, something that rarely gets mentioned in the literature – their amazing names.

Where else on a summer night can you encounter the Cynical Quaker, the Unarmed Wainscot, Drexel’s Datana. the Georgian Prominent or the Toothed Somberwing (photo of this last moth above)? Aren’t you intrigued by the existence of the Confused Haploa, the Girlfriend Underwing, the Honest Pero, and the Friendly Probole? What’s the story behind the Shattered Hydriomena, the Retarded Dagger, or The Laughter? How can you sleep at night when the Black-Blotched Schizura might be resting on your porch? What about the Goat Sallow, the Abrupt Brother or the Grateful Midget?

There are moths with more prosaic names, of course. The Reed Canary Grass Borer, for instance, leaves precious little to the imagination. Others, like the Spiny Oakworm Moth or the Yellow-Necked Caterpillar Moth, are named for their juvenile appearance, and bear little resemblance to their former selves. Many species are named for the plant their caterpillars feed on, or some youthful quirk of habit, like the Pecanleaf Casebearer and the Basswood Leafroller. Other species go by multiple aliases, depending on their age: Woollybear Caterpillars grow up to be Isabella Tiger Moths, and Hickory Horn Devils mature into the elegant and reformed Regal Moths.

Other names invite questions. Is the Dubious Tiger Moth any less trustworthy than its fellows? What happened to the Once-Married Underwing? Why is it not the Divorced Underwing instead? (That’s different, of course, from the Widow Underwing, which is an entirely different species.) Is the Nameless Pinion actually nameless? What is the Grieving Woodling’s problem, and is the Disparaged Arches moth really that bad?

Clearly, lepidopterists have a lot fun (and more than a few beers) when it comes to moth names. It’s time for the rest of us to catch up on the action. Fortunately, it’s never been easier to learn about moths. Flick on a light switch in the evening and see who shows up. Take pictures with a camera or smartphone and post them online to websites like BugGuide or iNaturalist for identification suggestions and tips. You’ll be amazed by how much is out there once you start looking.

If you live anywhere between Maine, Minnesota, Iowa and Virginia, you can flip through the excellent Peterson Field Guide to Moths of Northeastern North America by David Beadle and Seabrooke Leckie, which has color photographs of 1,500 of the most charismatic species you’re likely to encounter. Unlike old-school entomology displays, where dead moths are pinned with their wings spread, the Peterson Guide features live moths in their characteristic poses, just as you see them in the field. The endpapers have silhouettes of the family groups, so with a little practice, you’ll be distinguishing your Tiger Moths from your Tussock Moths and your Prominents from your Geometers, just like the pros. Similar volumes for the rest of the continent are expected to follow.

Sure, most people are excited when a charismatic megamoth like a Luna Moth shows up in their lives. The bright colors of the Showy Emerald or the Pandorus Sphinx will make even the most jaded naturalist’s night. But I’m always happy to see a Dusky Groundling or the Cloaked Pug, however drab and grey their markings. The Beggar and The Neighbor (not to mention the The Slowpoke) will always have a place in my heart. Even a Simple Wave is a cause for celebration. My field notes sound like I’m auditioning for comedy night at the local club – and that’s before The Bad-Wing shows up. And I can promise you this: as a student of moth names, I will never, ever be bored.

Vermont’s State Musician

HermitThrush-PFEIFFER

 

“Is that a bird?” asks one of my fellow Field Naturalist Interns, as we stand on an outcropping at Raven Ridge Natural Area on the border of Hinesburg, Monkton, and Charlotte, Vermont. When I told him that the song he was hearing was that of the Hermit Thrush he said that he had “never heard a bird sound so much like music”. I had never really considered the musical elements of birding before this comment and then felt compelled to look into the compositional stylings of the Hermit Thrush.

This medium-sized member of the genus Catharus (which also happens to be the state bird of Vermont) sings a song that is perhaps that most magical string of notes I have ever heard. Being somewhat of a musician and much more of a birder, I love listening to the song of the Hermit Thrush with its melodic, tumbling trills, like a flute harmonizing with itself. According to a number of auditory studies, the notes of the song of the Hermit Thrush are related to each other by pitch ratios that differ by simple integers of harmonic notes [1]. This discovery highlights the fact that the song is more similar to music produced by humans than to the songs of other birds that have also been studied in this way. It is also noted that certain harmonies produced by the Hermit Thrush are in line with those made by human music [2]. On top of all this musical jargon, it has also been discovered that this bird could be capable of producing other notes in its song, meaning that the species chose to sing in such an ethereal harmony.

You don’t need to have a musical background to appreciate the sounds of nature, the birds singing, the creaking of young trees as they sway in the wind, the croaking of a distant frog, or a stream gurgling and dripping down a mountainside. Among all of these sounds, however, nothing resembles music quite as closely as the song of the Hermit Thrush.

The Hidden Gems of Lake Michigan

This summer, transport yourself to the eastern shore of Lake Michigan, near the town of Petoskey, and perform a geological magic trick. Take a chunk of limestone on the beach – bland, grey and completely featureless – and dip it into the lake. Stare into the translucent depths at your chosen stone and watch distinctive hexagonal patterns emerge on the surface. But a funny thing happens when you pull the stone out of the water and let it dry in the sun – the markings abruptly vanish! What’s going on here?

As you might have suspected by now, this is no ordinary piece of limestone. Instead, you’ve stumbled across a Petoskey stone, beloved by geologists and beachcombers alike. Like all magic tricks, however, there is indeed a simple explanation for the vanishing act, impressive as it appears on first viewing. In this case, our mysterious rock’s origins in the distant past owe just as much to the animal as the mineral.

Four hundred million years ago in the Devonian era, Lake Michigan did not exist, but there was no shortage of water in the area. A wide, shallow tropical sea covered the area, home to a diverse array of bizarre-looking marine life: horseshoe crab-like trilobites, spiraling ammonites, brachipods and other shellfish, the first jawed fishes, sprawling crinoids and crustaceans. (When T.S. Eliot has J. Alfred Prufrock mutter, “I should have been a pair of ragged claws / Scuttling across the floors of silent seas,” he was probably thinking of the Devonian.)  It was also a golden age for coral, including one family – now extinct – known as rugosans, or “wrinkled,” on account of their distinctive appearance.

While many of these rugosan corals were solitary polyps, other species opted for a more communal approach. They massed together, forming vast reefs similar to the ones we see in our own era off Hawaii or Australia.  One of these colonial coral species, Hexagonaria pericarinata, was particularly abundant around the future home of Petoskey, Michigan. As the scientific name suggests, these corals were highly symmetrical, with each animal forming distinctive six-sided walls as it tried to occupy the maximum possible space against its many neighbors. (Unlike the rigid chambers you see in honeycombs, you’ll often find five, four, or even three-sided corals who just couldn’t grow up fast enough to compete with their more aggressive counterparts, or asymmetrical hexagons formed by polyps that got “squashed”.)

When individual polyps died, others grew on top of them and the cycle repeated. Eventually, whole reef conglomerates were buried by ocean sediments in the shifting seas. Time and pressure transformed the coral and sediment matrix into calcium-rich limestone, the coral polyps preserved as flattened outlines of their former, three-dimensional selves in the rock. Each polyp’s alimentary canal became a dark speck that forms the “eye” of each hexagon; the lines that radiate outward from the center mark where tentacles were located.

Fast forward to twelve thousand years ago in the Pleistocene. The tropical ocean vanished long ago, replaced by bare stone and a wall of glaciers three miles high. As the glaciers advanced and retreated, they scoured the bedrock, kicking up chunks of the limestone reefs and gouging out the depression that would fill with meltwater and become Lake Michigan. Rounded and sculpted by water, the fossilized coral fragments were moved by centuries of robust freeze-thaw cycles southward in the lake, occasionally washing up on beaches tens or even hundreds of miles away from their original site.

Dubbed “Petoskey stones” because of their abundance on the beaches and bedrock of Petoskey, Michigan, these stone corals are ubiquitous in gift shops throughout the state. You can find their likeness on a number of “Petoskey tchochkes” including magnets, bumper stickers and t-shirts, so residents and tourists alike can proclaim their love. As a sign of their distinctive popularity, Petoskey stones have been the official state stone of Michigan since 1965. They remain a source of local pride and a prize find during any lakeside stroll. Most stones you find on the beach are tiny, but huge storms can wash five, ten, or even twenty pound specimens out of the lake overnight.

Why are they easier to spot in water? The contrast between the slightly lighter crystals of fossilized coral body (calcite) and the surrounding stone is greatest when wet, making them easiest to detect underwater or well within the splash zone of the lake. (Further away from the lake shore, less discriminating rockhounds opt for spittle or other body fluids as a way to test their finds.) Some stones will naturally keep their appearance without water or any further treatment, but most of the stones available for sale have been professionally polished to ensure that the distinctive hexagons remain visible even when dry.

You can replicate the same look on stones you find on the shore with some fine-grit sandpaper, elbow grease, and a little toothpaste and velvet cloth for polish. Limestone is soft and easily eroded, so a little bit of effort goes a long way – a conventional rock tumbler is overkill, converting beautiful stones into a dusty pile of sediment. But maybe you’ll keep any stones you encounter in their natural state, tucked away in your pocket, ready to perform a magic trick of your own.

A Passionate Pollinator

Summer blockbusters at the multiplex are big and bold, but equally dramatic spectacles are happening outside as plants send up blooms to attract insect pollinators. While sunflowers and zinnias command quite a following, and anise hyssop and bee balm have their charms, the best show in town right now in central North Carolina is at the maypop—also known as the purple passionflower—hands down.

Colorful and vivid, with a curtain of tye-dyed strips surrounding a pillar of five anthers perched below three ovaries, any of the five hundred plus species of passionflower would fit right into a bouquet designed by Dr. Seuss. Some see the flowers as strangely clock-like; others view it as living metaphor full of religious symbolism. Despite its exotic appearance, however, the delights of passionflowers aren’t limited to the tropics. Five species can be found growing throughout the southeastern United States, and the maypop (Passiflora incarnata) is one of the hardiest of the lot, ranging as far north as Pennsylvania in the wild.

Unlike many native perennials, which need specialized environments in order to thrive, the maypop is not fussy about its living space. It’s aggressive and vigorous, flourishing in full sun and disturbed areas, even in years with little rainfall. It clamors up over other plants in a race to get ahead, twining tendrils and pulling no punches, to the point where it’s occasionally listed as an agricultural weed. It can grow as much as fifteen feet in a season before dying back to the ground with the frost. This drive to survive at all costs, coupled with its showy purple and white blooms and edible fruit, has made it a beloved staple of Southern gardens. And with it come the pollinators.

Eastern carpenter bees (Xylocopa virginica) look and act much like their bumblebee cousins, with a few twists: bigger, buzzier, and boasting black and shiny abdomens. Aside from the occasional misstep of burrowing into wooden structures, they rarely bother humans. Like all bees, they are important pollinators for flowers—except when they “cheat” by nipping flowers at the base to get a quick hit of nectar.

The maypop, however, has an ingenious mechanism to foil cheaters. Instead of having a curled base for nectar storage, all of the good stuff is located at center of the flower’s disk. In order to reach it, however, the bee has to brush against at least one of the five stamens—conveniently located just the right height for a carpenter bee—which smear pollen all over the bee’s head. Once the bee is finished at the first flower, it will have to rub up against the receptive stigmas of the next flower in order to drink more nectar, thus ensuring successful pollination. I’ve never seen any of them stop at just one flower! Occasionally, a tiny wasp or a Japanese beetle might slip in to steal some nectar, but the vast majority of insects I see on maypop flowers are carpenter bees, obliviously pollinating away while they gorge on nectar.

And thus arises the other wonder of the maypop—namely, its fruit, which closely resembles its commercially grown tropical cousins in size and taste. You may think you’ve never tasted a passion fruit, but guess again—its distinctive flavor adds a kick to the popular fruit drink Hawaiian Punch. The egg-sized fruits—technically berries—fall to the ground when ripe, and can be eaten out of hand. They can also be used in jams and jellies, although I’ve never met anyone who’s managed to make it that far with them.

Dinner and a show—who could ask for anything more on a hot summer day?

Southern Comfort

The grande dame of its family, the southern magnolia dominates the landscape. There is simply no overlooking its stately elegance, especially when it is in full bloom. Bearing flowers as wide as your face—worthy of the epithet grandiflora, “big-flowered,” indeed—a southern magnolia is no mere tree. A southern magnolia is an experience.

Let’s start with the blooms. Following a design ancient by evolutionary standards, they are similar in structure to the first flowers that appeared in the Jurassic era millions of years ago, a testament to success. Large simple petals, pearly in color and texture, fold over a bizarre-looking yellow cone-like structure at the center. Yellow stamens fall like matchsticks from the base of each cone—actually compendium of simple pistils—and collect in the folds of the petals. Once the flowers have been fertilized, the petals fall back in a brown and crinkled heap as fleshy red fruits dangle on tiny white threads from the now-green and black cone. Until that happens, though, the scent is heavenly—alternately described as lemon, citronella, or jasmine—as an enticement to its beetle pollinators.

Meanwhile, the rest of the tree is equally impressive. The leaves are stiff and papery, green and waxy above and fuzzy brown velvet beneath. Typically boasting a single trunk, each tree stretches into a classic pyramid, broad at the base and narrowing to a single point at its apex. Given enough time and space to reach mature size, each magnolia tree becomes its own island, its lower branches hovering just above the ground, the evergreen leaves above form a dense canopy under which nothing else can grow. Blocking out the sounds and view of the world outside, each tree becomes a miniature oasis. A grove of mature trees forms a graceful archipelago—truly a sight to behold. Even in winter, the southern magnolia bears the occasional snowfall or ice storm with grace.

With the possible exception of live oaks, no trees are more evocative of the archetypal South than the southern magnolias. Yet they are true natives only to a swathe of the southern Carolinas, Georgia, Alabama, Mississippi, and Florida. Known colloquially as “bull bay,” they join their cousin Magnolia virginica, the sweetbay, and the unrelated redbay and loblolly-bay to grace the swamps and pocosins with their presence. Left to their own devices, they would never have made it further into the uplands. Fortunately for gardeners everywhere, the southern magnolia thrives outside of its natural range, even when pushed to its limits. One such specimen can be found in Burlington, in the courtyard of Marsh Life Science building on the University of Vermont campus, where sheltered walls and a south-facing aspect create a microclimate warm enough for this southern tree to survive harsh New England winters.

Moreover, the southern magnolia is versatile in the human-dominated landscape: I have also seen it growing as a street tree in Monterey, California and lining parking lots and new developments in Cary, North Carolina. However, most of the trees used in the modern horticultural trade are dwarf cultivars that will never reach the width and stature the species is capable of. Although my heart is gladdened to see them, I cannot help feeling wistful, as if something important has also been lost.

Climbing those older, giant trees was an essential staple of my childhood. The wide, thick limbs were easy to scramble up with the ease of a squirrel, offering real height and perspective. For a time, I was removed from the cares of the world and fully immersed in the world offered by the trees. Attending college along the Chesapeake Bay in Maryland, the southern magnolias grove tucked away in a sheltered courtyard soothed my soul during times of anxiety and change. The arbiter of student discipline, the Assistant Dean, had an office directly facing those trees, so I never found the courage to climb them. Still, I valued those trees for the reminder that I was not too far, ecologically speaking, from home.

It’s May now, and the southern magnolias are blooming again in the gardens of my hometown in North Carolina. When I breathe in the scent of its blossoms, I am in my childhood again, that long golden summer where anything is possible and no height is unattainable.

The Noble Sporophyte

Moss sporophytes emerging from a clump of moss. By Bob Blaylock. Image licensed under creative commons by Wikipedia.

Moss sporophytes are tiny, slender structures that pop out of moss in droves. Their beauty, diversity, fun-factor, and cute little caps continually amaze me. Like a big buzz cut, they tickle my hand as I graze them. If I am lucky, they are ripe and release their spores in a small flurry, sending a miniature cloud of dust eight inches forwards. The spores melt away into the air, quickly invisible to the naked eye. Usually, I brush the clump again and again, and the sporophytes repeat the trick until the caps are emptied of their spore dust. Eventually, some of the spores will germinate to grow new moss plants.

Over the five years that I earned my living teaching outdoor programs, I taught several hundred people about sporophytes. I would have the group help me find a promising patch of moss, and with reverent enthusiasm, I would show my students the petite sporophytes. Then, I would share the three reasons that sporophytes had captured my heart to become one of my favorite things in the forest.

First of all, I didn’t know that they existed until I was in my 20s, and once I knew to look for them, I saw them almost everywhere there was moss. This was an astounding discovery, and one of the most poignant, eye-opening experiences of my college years. I had been oblivious to the ubiquitous and entertaining sporophytes all around me, and it was amazing to have my eyes opened just by learning to look for them.

Next, I would demonstrate the gorgeous diversity of the sporophytes. The stalks are often iridescent, and many of them exhibit a gradient of hues. For example, some range from gold to deep, metallic purple.The spores are also often brightly colored, sometimes in surprising ways. I have dissected sporophytes that revealed bright orange, white, or dayglow green spores. And the stalks are always fine and flexible, which means that they “boing” in a tactilely-satisfying way.

Finally, I would show the participants, adult or child, how fun sporophytes are by running my hand through the tuft. If I judged the clump well, and was lucky, a cloud of spores would gently whiff from the cluster of stalks. Everyone would take turns helping the spores fly free. Invariably, some excited participants would spend the rest of the program looking for other clusters of ripe moss sporophytes.

Moss sporophytes illustrate some of the most important reasons that humans need the natural world. They invoke wonder, are beautiful and fun, boggle minds with their diversity and scale, and inspire curiosity. For those who have never really noticed them, they encourage humility by reminding us how little we see and understand each day, even when it’s right in front of us. Moss sporophytes provide an opportunity for people to interact with nature in a hands-on way, and in doing so, people help the little plants send their spores into the wind. The experience is tactile, guilt-free, and doesn’t require any special equipment.

As the spring rains feed the forests, fields, and yards around you, keep an eye on your local moss patches. The mossy marvel of a ripe sporophyte might be waiting at your feet.

Secrets of The Vault

Sean and I are in The Vault. We’ve been here for a while—hours now. It’s less grandiose than it sounds, really just a back room in the Charlotte Town Hall, but it gives me the same feeling I get from the New York Public Library or a fancy art museum. Tread lightly, the walls are saying. Look closely. We have secrets for you.

What’s amazing is that the secrets of The Vault are not really secret at all. Every document in the room is in the public record, even the original map of the Town of Charlotte, hand-drawn in 1763. The massive red books of land records, the card catalogues of births and deaths—these pages of history are not preserved behind glass; we are perfectly free to look at them. I can reach out a hand, every now and then, to gently trace this two-hundred-and-fifty-year-old calligraphy.

We’re here to research the UVM Natural Area at Pease Mountain, a prominent hill directly west of the Charlotte Town Hall and just north of Mount Philo along the Champlain thrust fault. This semester, our cohort is performing a Landscape Inventory and Assessment of the area. We’ve spent several weekends strolling along the mountain’s broken quartzite ledges, and we’re starting to get a sense of the property’s natural resources. The soil is thin but rich, patterned here and there with the frostbitten remains of last year’s hepatica leaves. The trees are not the usual beech-birch-maple assortment we expected, but a variety of species used to warmer, drier climates: peeling trunks of shagbark hickory, gnarled red oaks, bitternut hickories with their sulfur-yellow buds. We’ve noticed hints of other mysteries: a road cut here, an old stone foundation there. UVM acquired the property in 1949; Sean and I want to know who has owned Pease Mountain–and what it’s been used for–as far back as the town’s records go.

20160329_105958

First subdivision of the town of Charlotte.

We start by looking in the Index, a twenty-pound tome containing a list of every land transaction undertaken in Charlotte until the book ran out of pages around 1960. Thankfully the Index is alphabetized and we quickly find the record we need: “Jeanette S. Pease Phelps and George J. Holden to University of Vermont and State Agricultural College.”

I’m immediately absorbed in the web of archaic legalese that follows: “Now, know ye, That pursuant to the license and authority aforesaid, and not otherwise…We do by these Presents, grant, bargain, sell, convey and confirm unto the said University of Vermont…the following described land…Being Pease Mountain, so-called, in the town of Charlotte.” The deed was written barely more than half a century ago, but it reads like something from the middle ages. The solemn tone is compelling. I can picture the occasion, the buyers and sellers grouped around a table, poised to sign below the words, “In witness whereof, we hereunto set our hands and seals…”

We follow the trail further and further back, tracing property descriptions bounded by increasingly vague terms: “…to the N.E. corner of said lot to a maple stump with a cedar stake in said stump. Thence southerly on the west line of said owned by Everett Rich to a cedar stake & stones in the S.E. corner. Thence westerly on the north line…” The record books get thinner as we travel back in time, the pages more brittle, the writing fainter. Eventually we find ourselves scrutinizing a gridded map: the second subdivision of the town.

Accompanying the map with its numbered parcels, we find a list of the original owners of those parcels. Lot number 1, which at the time encompassed most of Pease Mountain, is ascribed to “Glebe for the Church.” We puzzle over this. Who was Glebe? We haven’t heard any mention of him in more recent deeds. Was he a minister?

Glebe for the Church. It sounds like a momentous designation. We finally think to Google the strange phrase, and we discover the ancient tradition of glebe land. It’s not a person after all, but a kind of conservation easement. When Vermont’s first towns were established, certain plots of land were set aside to remain undeveloped. These lands were leased to farmers or timber harvesters in exchange for a rental fee, which paid for municipal costs or, in this case, the upkeep of the parish. For hundreds of years, Pease Mountain was preserved by this tradition.

As we leave the Town Hall, Sean and I glance up at Pease. Our journey through the handwritten history of Charlotte has given us a deeper sense of this place. As we’ve walked there with our cohort we’ve mapped natural communities and forest stands, discovered vernal pools and views over the lake. But walking and looking can only take us so far back. Beyond the oaks and hickories, the purple cliffs, the porcupine and bobcat dens, there is another Pease Mountain story. It’s no longer legible in the landscape. But luckily for us, it’s all written down in the record books.
