Ephemeral Magic

Southern gardens are known for their big charismatic flowers: sugar-pink rhododendrons, peppermint domed mountain laurels, wedding cake layers of American dogwood, giant lemon-scented magnolias. These flowers are exciting, but don’t forget to look down at what’s growing closer to ground level.

When I was a kid in the Ozarks, I learned that the first signs of spring weren’t to be found up in the branches of the forest or out in the sunny meadows. Spring came first to the forest floor.

Bloodroot (Sanguinaria canadensis) was the earliest to appear. Its tiny daisy-like flowers, with yellow centers and white rays, only lasted for a day or two. Next, we’d get a wave of violets – both the common purple (Viola odora) and downy yellow (Viola pubescens). A week or two later, the woodland phlox (Phlox divaricata) would bring drumettes of powder blue to hilltops – we’d gather the flowers in fistfuls and shove them into mason jars, filling the house with sweet scent. While the phlox was bright on the hilltops, sessile trillium (Trillium sessile) would carpet the ground in lower areas, mottled foliage topped with flecks of burgundy flower. Once spring had really arrived, the shooting stars (Dodecatheon meadia) and puttyroot orchid (Aplectrum hyemale) would send up flowers in the flickering shade of a new season’s foliage. Every week, something fresh fluttered into bloom – to be overcome the next week by a new glory.

When I visited the Reserve last spring, I kept moving slowly – camera snapping, barely inching my way along – because I was fascinated by the wonderful tapestry of ephemerals covering the ground. Old favorites from my childhood, like Solomon’s Seal (Polygonatum biflorum) and herb robert (Geranium maculatum) achieved fairy-tale sizes in the soft weather and abundant rain of the mountaintop. Mayapples (Podophyllum peltatum) lifted happy umbrellas above the forest floor. I’d never seen some of these plants thriving at lower elevations – rosy wake-robin (Trillium catesbaei) and lady’s slippers – both the pink (Cypripedium acaule) and yellow (Cypripedium parviflorum).

The garden team at the Reserve is doing a phenomenal job of fostering existing woodland plant populations while also enhancing them with strategic new plantings. One genius strategy that Kelly’s using is to plant intermingled drifts of differently-colored selections of the same species (such as woodland phlox, Phlox stolonifera) to create beautiful color variations within mass plantings. I’m excited to see how these ephemeral plant communities continue to evolve.

woodlands, forests, gardening

Even if you don’t have the existing root and seed bank of the Reserve, you can make a dynamic woodland garden of your own. Find an area with with light shade – beneath the canopy of deep-rooted trees or in bright building shadow is great. Keep the soil stabilized with a groundcover that leafs out late – ferns or sedges are great options. Then, choose a handful of different woodland ephemeral species and try them throughout your chosen location. I’d just plant a few to begin with – maybe a dozen of each – and spread them across the site to see how they do. After 2-3 years, you’ll see how they’re settling in. Make some mass plantings of the ones that do well. In just a few years, you too will be doing a spring shuffle as you gaze down at your ever-changing carpet of woodland delights.

Much of this season at the Reserve has been spent inside enhancing our digital plant database in preparation for it to be shared with the public, as well as making plans for the coming growing season. On warmer days, we have been able to get outside for some much-needed landscape maintenance including cleanup after winter storm Diego swept through. Several top-heavy rhododendrons were uprooted and toppled over from harsh winds and the added weight of ice and snow during the storm. We have replanted, staked and covered them with horse manure for extra protection while they become reestablished. We also top-dressed beds, shrubs and small trees that had been recently planted. The Wildflower Labyrinth is one exception with regards to manure because excess nitrogen will cause these plants to become leggy and fall over.

In preparation for the completion of our new Nursery Complex trail, we transplanted several cinnamon ferns from the path to nearby locations a few feet away. Our water mitigation efforts continue as we have added oak and maple logs—LWDs (large woody debris)—to woodland areas along topographic lines where elevation changes. This is the first stage of a multi-step process to create bio-swales that will help prevent erosion. Later we will revisit those logs to partially bury them in the soil, and then dig out an adjacent area uphill and refill it with small woody debris like wood chips. This will hold the water in the basin and allow it to slowly seep into the ground rather than quickly run off. The woody debris will also gradually break down into a rich organic matter and provide added nutrients to the surrounding plants and soil.

Inside, we have been laying the groundwork for additions to the gardens. Seed stratification is a naturally occurring process of long periods of cold temperatures breaking seed dormancy and beginning germination. Natural forces throughout the seasons deteriorate the seed’s external coating, allowing water and light to reach the embryo. Horticulturalists mimic those natural forces indoors for propagation. We place the seeds in moist mediums like sand, peat moss or a paper towel in airtight containers inside the seed storage refrigerator for 1 – 12 months depending on the requirements of each species. Some seeds require double dormancy; one cold period is not enough for these slowly germinating species. After the first few months in the refrigerator, they need to warm up for a couple more months and then go through a second cold cycle. The seeds are then ready to be planted in warm soil after the last frost date in spring. It is possible to follow nature’s process more directly and sow seeds outside either in-ground or in containers during the fall, but be aware that they are not as protected from being eaten by animals or killed by a late freeze.

At the Reserve, we start the process in our seed chamber with a system that can be easily set up at home for horticultural enthusiasts using a baker’s rack, UV lights and heat mats. Right now, we are stratifying milkweed, hibiscus, lobelia, Turk’s cap lily, magnolia and strawberry bush among others. We are also germinating native azalea seeds (pinkshell and Gregory Bald hybrids), red spruce as well as other native plants for our annual Plant Sale in the fall. This early start will provide a longer growing season than naturally occurs at our high elevation.

For those of you eager to stay connected with your garden throughout the year, we offer some timely tips for chilly days:

  • It has been said that some of the best gardens are built in the winter by a fire. We suggest you spend some time simply walking through and around your garden during this bare-bones season to observe at the deeper level, and then warm up inside while you sow your plans for the coming growing season.
  • Make note of what worked and what didn’t during the last season so that you can have a more fruitful garden in the coming year.
  • Meet with an arborist to learn more about how to best care for your trees and consider winter pruning of crossing branches, damaged limbs or canopy release.
  • It’s a great time for grading projects should you want to transform the lay of the land for improved water flow (away from your foundation), erosion control or simply for an enhanced design.
  • Winter is also a fine time to remove invasive species, especially English ivy. No mosquitos will bother you and the robust workout you get from tugging at those tough roots will keep you warm.
  • Finally, when you’ve had all you can take of the cold, it’s nice to warm up back inside and peruse catalogues for seeds, bulbs, tubers and anything else you plan to add this spring.

Southern Highlands Reserve’s Volunteers of the Year

Posted Posted in SHR-News

Southern Highlands Reserve is pleased to announce the 2018 Volunteers of the Year! Volunteers are vital to our success as a growing non-profit organization and we’re pleased to honor these individuals for their exceptional commitment and support of our mission. The Volunteer of the Year Award recognizes an outstanding volunteer for his or her valuable and selfless dedication and contribution to enhancing efficiency within the organization as well as spreading awareness throughout the community.

This year, we had a tie! Two shining members of SHR’s extended team stood out equally. We are pleased to recognize Molly Tartt of Brevard, NC and Paul Cooper of Lake Toxaway, NC as the 2018 Volunteers of the Year.

As a member of the Waighstill Avery Daughters of the American Revolution (DAR), Molly Tartt worked with her group to find a long-forgotten red spruce forest originally planted by the DAR in the 1940’s near Devil’s Courthouse off the Blue Ridge Parkway. Deeply inspired by this history, she became a strong supporter of our red spruce restoration work. Molly works in our Nursery Complex repotting young red spruce and is an avid supporter of us within the community.

Paul Cooper is a long-time volunteer at the Reserve. A resident of Lake Toxaway Community and a nature enthusiast, Paul holds a special affinity for the Reserve. Each year, he logs more hours than any other volunteer. His love of story-telling and the Reserve make him a natural fit as our Visitors’ Days docent!

We are so grateful to all volunteers who helped us make 2018 a successful year.

Contact us to learn about becoming a Southern Highlands Reserve volunteer in 2019.

Sprucing Up the Forest for Fairy Diddles

Posted Posted in SHR-News

Commission biologists lead habitat restoration projects to benefit the Endangered Carolina Northern flying squirrel

“It won’t bite. It just needs a launch point,” I say. The flying squirrel scurries up the front of the kid’s sweatshirt to his shoulder, pauses to gather itself, then launches into the air. In its panic, it lands short of the nearest tree trunk but scrambles the last few feet, bolting behind it, then dashes up the trunk. From a branch it peers down, its big black eyes blinking at us.

The rest of the students, giggling a few seconds ago, are now hushed with mouths agape, staring back at it. Someone steps closer with a camera and the flying squirrel jumps, floating off in a slow glide down the mountainside. Demonstrating remarkable maneuverability, it banks a hard left to sail past a tree branch and out of sight. The whole course of its glide, which lasts seconds, is accompanied by a chorus of “whoa!” and “that was awesome” and awed laughter.

It is like that every time. There’s something magical about a flying squirrel. No wonder its folk name is “Fairy Diddle.” I prefer to call them “flyers.”

I turn back to the class of aspiring wildlife biologists who attend Haywood Community College. They are helping me check squirrel boxes in the Great Balsams, just up the road from their campus in Clyde. I had just finished measuring and tagging this flying squirrel and put it back in its nest box. I can’t make a scurrying sciurid stay put though. This one busted out and dropped to the forest floor right smack in the middle of 20 students, cueing a teachable moment.

“Flying squirrels aren’t capable of powered flight,” I say. “They glide by pushing off with powerful hindquarters, extending their fore and hind legs, and spreading out their patagium.” I demonstrate the patagium (or “wing” membrane) with my arms wide. “To do this, they need a tree for launching.” I turn

to the student who served as a human launch beam. His expression lies halfway between amused and embarrassed. “Or something tall that serves the same function. An Endangered species just used you as a launch tree. Consider yourself lucky.”

Actually, each student was fortunate that day. Sometimes we check boxes without finding any squirrels. Just 10 percent of the roughly 350 boxes checked each winter are occupied. This is no ordi­nary flying squirrel. It’s the Carolina Northern flying squirrel, a critter you are only likely to see if you’re really looking for it.

Flyer 101

North Carolina is home to two species of flying squirrels. Both species of these gliding tree squirrels are nocturnal cavity-dwellers. The smaller, grayish-brown Southern flying squirrel is found through­out North Carolina at mid to low elevations, where it subsists on nuts and seeds. The rarer Carolina Northern flying squirrel dons a cinnamon-brown coat and is found only on 13 massifs in North Car­olina, Tennessee and Virginia’s highest mountains.

In 1985, the U.S. Fish and Wildlife Service listed the Carolina Northern flying squirrel as Endangered, due to its limited and discontinuous range making it vulnerable to habitat destruction, fragmentation or alteration. Biologists noted par­ticular concerns about past and future clearing of forests, introduced insect pests such as the Balsam woolly adelgid, recreation and other development, pollution (heavy metals, pesticides and acid rain) and the potential for global warming further limit­ing its range.

Despite their similar appearance and ability to glide, North Carolina’s two flying squirrels differ in key aspects of their ecology. The Carolina Northern flying squirrel lives in North Carolina’s so called boreal forest zone, selecting cool, moist, north-facing slopes. Its haunts are the dark spruce, fir and birch forests above 4,500 feet elevation. There, it consumes truffles, buds, fruits, lichens and anything from bird eggs to nestlings to crayfish.

Our acoustic surveys and radio-telemetry track­ing data have made it clear that Northern flying squirrels prefer mature conifers. In fact, according to research by Dr. Cordie Diggins and Dr. Mark Ford of Virginia Tech, Carolina Northern flying squirrels have smaller home ranges in high-quality habitat of taller conifers, foraging nightly in the spruce and fir. Why so? The answer may have something to do with the truffles they eat.

As if its gliding ability was not captivating enough, this flying squirrel’s role in forest dynamics is also fascinating. At night, they parachute down from the trees to dig for truffles, the fruiting bodies of mycorrhizal fungi associated with the roots of spruce trees. The mycorrhizae form a fibrous net around the roots of the tree, helping the tree capture water and nutrients. The fungus in turn obtains sugar from the tree.

To a flying squirrel, the tasty, nutritious part of the truffle is the tough outer skin. However, they inadvertently ingest some of the spores at the center of a truffle. The undigested spores are dispersed across the forest floor in the flying squirrel’s droppings. Other small mammals, such as red-backed voles, do much of the same. However, the flying squirrel’s unique gliding locomotion enables it to cover larger areas, dispersing spores broadly. Thus, Dr. Peter Weigl, the preeminent authority on the Carolina Northern flying squirrel, noted that it effectively perpetuates its own habitat. But in some parts of their range, where past land use has drastically altered the forest, the flying squirrels can’t do it alone. They need our help.

Changing Times and Trees

On a chilly mountain morning in June, my crew is parked at Black Balsam, donning winter coats and hats. Joining us is volunteer Julie Wade, a wildlife student at Haywood. I fit Julie with an external frame backpack to which I have strapped three ammo cans housing devices that will record the vocalizations of flying squirrels. We’re collecting baseline data on flying squirrels in an area slated for habitat restoration. In a few months, we’ll be planting nearly 1,000 red spruce seedlings with the help of Julie and her classmates.

First, we want to see if Northern flying squirrels persist here. I have my doubts because the habitat is degraded. Between 1905 and 1920, spruce was logged from every corner of Haywood County’s high mountains reachable by railroad. The extraction did not employ the sustainable practices used today. In several areas, including the forest we’re about to survey, the slash caught fire. Raging fires in 1925 and 1942 incinerated soil and led to erosion during storms and freeze-thaw cycles. Thus, the loss of habitat that led to the Carolina Northern being listed as Endangered happened over a discrete window of a mere few decades. Mind you, no one even knew about the Carolina Northern flying squirrel back then. It wasn’t discovered in North Carolina until 1953.

Across this moonscape of eroded soils, a forest began to recover, only it was not the same forest as before. The spruce-fir forest is not a fire-adapted community. The normal forest dynamics here occur at the scale of individual tree fall gaps. In this newly cleared, soil-depleted setting, acres of blackberry and pioneer hardwoods like fire cherry replaced the spruce and fir that had once grown alongside yellow birch and sugar maple. The forest we now survey features a canopy of 70-year-old yellow birch, with mid-story birch, sugar maple and buckeye. Spruce occurs in small clumps, with some individuals reaching the canopy, but the majority in the mid-story shaded by hardwoods.

That spruce and Carolina Northern flying squirrels persist here seems unlikely. But they have, thanks to flexibility in their life histories. For example, the Northern flying squirrel is not restricted to conifer forests or a diet of truffles; they will use Northern hardwood stands in the absence of conifers and eat a varied diet. Likewise, while red spruce grows faster in the sun, it is not restricted to open areas. Spruce is remarkably shade tolerant. Individuals sometimes sit in the shade of hardwoods for 50 to 100 years ready to grow into the next tree fall gap. And so both remain, but over a much shrunken range and in a heavily altered forest.

But their plasticity has its limits. One threat the Northern flying squirrel faces is upslope encroach­ment by the Southern flying squirrel. Unlike the Northern flying squirrel, which can subsist on the nutritious oils of Usnea lichens when the snow piles up, the Southern flying squirrel’s small body size demands a constant, cacheable supply of nuts and seeds to survive winter’s cold. The lack of such a source of hard mast in the spruce zone seems to limit Southerns from becoming established there as a year-round resident. Warmer winters may increase contact between the two species, as the Southern flying squirrel ventures upslope, bringing with it the parasitic intestinal worm Strongyloides robus­tus. The Southern flying squirrel fares well when infested by this parasite, but the Northern flying squirrel does not.

Planting for the Future

A healthy, robust Northern flying squirrel popula­tion needs high-quality, well-connected forest habitat. Restoration of this forest community is the mission of the Southern Appalachian Spruce Resto­ration Initiative (SASRI), which formed in 2012 and is a partnership among agency biologists, non-gov­ernmental organizations, university researchers and nonprofits. SASRI partners guide restoration objectives and propagation, planting and monitoring efforts. One of SASRI’s objectives is to restore conifers to hardwood-dominated stands, creating a mixed forest. Another goal is to restore connectivity between patches of high-quality habitat to enable dispersal of the squirrels.

In some areas, large swaths of blackberries sepa­rating forest patches exceed the flyer’s glide distance (and tall students are unlikely to be standing at the ready as squirrel launch pads). Squirrel-sponsored spore spreading may achieve these objectives, but at a snail’s pace and only in those areas having a spruce seed source. Biologists and foresters can speed up the process by planting spruce seedlings where they are scarce and releasing existing seedlings to sunlight to accelerate growth. Release is accomplished by selectively cutting hardwood trees shading vigorous spruce trees in the understory.

First though, we need seedlings—preferably locally-sourced seedlings. The nearest are in West Virginia, so we grow our own. Each autumn, I find myself crouched beneath towering spruce trees, picking fresh red cones off the forest floor and drop­ping them into brown paper bags. Fingers sticky with sap, I leave the cool mountain top to deliver my cone haul to The Southern Highlands Reserve, a native plant arboretum and research facility on Toxaway Mountain in Transylvania County. Their small staff have grown spruce for 10 years and are experts at extracting seed from cones, cataloging the germinating plants and growing such vigorous seedlings that they prefer to call them small trees.

Since 2013, spruce has veritably taken over the Reserve’s nursery space. The four restoration efforts implemented thus far clear out the nursery in a matter of hours as partners load trucks and trailers with trees bound for the woods. The experience leaves Southern Highlands Reserve Director Kelly Holdbrooks reeling with a mix of excitement for contributing to conservation and sadness to see the trees go. Her sadness is short-lived as she turns around to start the next batch of seedlings that will be needed.

In September, we’re back at the Black Balsam parking lot having just cleared out the Reserve’s seedling stock. The restoration site is 1 mile from the parking lot. Volunteers from hiking clubs and trail maintenance crews spend two days hauling seedlings down the trail. Haywood instructor Shan­non Rabby distributes hard hats and shovels to his forestry students. Everybody leaves the parking lot with a sack of red spruce seedlings. The seedlings are freshly watered, weighing that much more.

The students bring enthusiasm to the planting days, despite having never seen a Carolina Northern flying squirrel. They plant the trees quickly (hoping to exceed the number planted by Warren Wilson College’s forestry crew which will plant later that week) but they plant with care. Throughout, they pepper me with questions and ideas about release work and monitoring. Their forestry education comes to life with each seedling they bury in the ground. A few muse that they want to see these trees in 30 years. And of course, they all want to see a Carolina Northern flying squirrel. So, I invite them back to help me check squirrel boxes in the winter. I can’t promise we’ll catch any Northern flying squirrels, but if we do, maybe someone will be lucky enough to serve as a launch pad.

What is SASRI and Why Do We Care?

Posted Posted in SHR-News

The Southern Appalachian Spruce Restoration Initiative (SASRI) 2018 annual meeting took place on Thursday, November 8 at the Bent Creek Experimental Forest outside of Asheville, North Carolina.

This partnership of people from diverse interests was formed in 2013 for the common goal of restoring spruce-fir ecosystems across high elevation landscapes of the Southern Blue Ridge. Referred to as “Islands in the Sky”, these pocket ecosystems at one time covered vast expanses of mountain landscape, but are now only found sparsely in western North Carolina, eastern Tennessee and southwest Virginia.

After the Everglades in South Florida, spruce-fir forests are the second most endangered ecosystem in the United States. Over the last century, they have been greatly reduced across the southern Appalachians largely due to logging. Adding insult to injury, severe slash fires 100 years ago were followed by rains washing away the seed and soil profile necessary for species regeneration. Growth is slow at high elevations making the regeneration that much more of a challenge. Most red spruce present today were planted in the 1940s as a restoration effort after those fires, with current restoration efforts still attempting to replace what was lost then. Today the spruce-fir forests face increased pressure from acid rain, rising temperatures, poor management and drought.

Red spruce was chosen as the best species for restoration because it is the conifer least in decline. Another significant motivating factor for choosing red spruce was to help the Carolina northern flying squirrel, a federally endangered species. This squirrel feeds on mycorrhizal fungi, or truffles, that grow at the roots of red spruce. Also, southern Carolina flying squirrels carry a harmful gut parasite that they pass along to northern Carolina flying squirrels where their territories overlap. The oil from red spruce staminate cones that the squirrels feed on suppresses that parasite, protecting their overall health. Not only home to the northern Carolina flying squirrels, these forests also support the federally endangered spruce-fir moss spider as well as other species of conservation concern such as the norther saw-whet owl, black-capped chickadee and several salamander species.

SASRI, comprised of private, state, federal and non-governmental organizations, recognizes the importance of this ecosystem for its ecological, aesthetic, recreational, economic and cultural values. Some of the other organizations involved include the US Fish and Wildlife Service, US Forest Service, The Nature Conservancy, NC Wildlife Resources Commission, Blue Ridge Discovery Center, Grandfather Mountain Foundation, NC Forest Service and Appalachian Mountain Joint Venture. As a founding organization and continuing Steering Committee and Planting and Propagation Committee members, we spent the day with our partners and interested parties discussing updates and findings from the past year. SHR Executive Director Kelly Holdbrooks and Director of Horticulture Eric Kimbrel gave a presentation on the status of our red spruce propagation and discussed some of the coming projects to propagate for new public land sites.

In the spirit of the Reserve’s mission to protect and conserve native plants and their ecosystems, we are dedicated to helping reverse the decline and reinvigorate the vitality of spruce-fir forests in the Southern Appalachian Mountains. Due to our high-elevation location, our Nursery Complex is uniquely poised to grow red spruce seedlings successfully. Currently, there is no other facility in the southeastern US growing red spruce for restoration, which makes the Reserve’s ability to continue these propagation efforts for this partnership very important.

Southern Highlands Reserve Helps Rescue Native Plants at High Hampton Resort

Posted Posted in SHR-News

Southern Highlands Reserve recently had the opportunity to assist in a local native plant rescue at the historic High Hampton Resort in Cashiers, NC. A redesign of its golf course by award-winning course designer Tom Fazio involved expansion into previously wooded and undeveloped areas. As such, a wide variety of native plants and wildflowers needed to be cleared.

In June, while hiking through the areas for future golf greens and admiring the flora, homeowners Sally Price and Beth Preston, along with High Hampton Vice President Owen Schultz, began discussing the possibility of saving many of these plants prior to construction. Price, who holds a native plant studies certificate from Birmingham Botanical Gardens, and Preston quickly volunteered to lead the effort so that residents would be able to collect plants and relocate them to their private properties—a benefit not only to the homeowners, but also to the overall ecosystem at the Resort. Able to increase their individual plant populations and potentially gain new species, these good stewards of the community also helped preserve the system’s existing state of balance.

They contacted local native plant experts, including SHR Executive Director Kelly Holdbrooks and Director of Horticulture Eric Kimbrel, along with Adam Bigelow of the Jackson-Macon Conservation Alliance, Jeff Zahner of Chattooga Gardens in Cashiers and Preston Montague of The Native Plant Podcast. With various backgrounds related to native plants of the region, this group came together to help identify species valuable for relocation and educate homeowners on best practices for plant transport and replanting to ensure long-term survival. In return, High Hampton Resort generously allowed SHR to harvest and transplant a total of 100 new plants— including trilliums, jack-in-the-pulpits, yellow lady slippers, orchids, shining club moss, fawn’s breath, wild ginger, partridgeberry and featherbells—to the Reserve.

Global deforestation and loss of habitat is ever increasing from human activities such as large-scale agriculture, logging, mining and infrastructure construction. A record was set in 2016 with 29.7 million hectares (73.4 million acres) of global tree cover loss [1]. We are grateful to the High Hampton Resort members who had the awareness to conserve and preserve within their own community when the opportunity arose.

Gardener’s Corner

Posted Posted in SHR-News

Autumn, marked by cooler weather and shortening days as Earth’s axis begins to tilt away from the sun, transitions us from summer’s lush abundance to winter’s quiet dormancy, and refers in its origins to the passing of the year. Once commonly referred to as harvest, western cultures have lost that broader association with the land since becoming predominantly urban.

At the Reserve we are, of course, still very tied to nature and its rhythms, and are working on timely tasks dictated by the Earth’s rotation and the seasons it creates. Harvest, autumn or (the preferred term in the United States) fall, has us collecting those fallen leaves to shred for leaf mulch in beds and bare spots. While hardwood mulch is preferable for trails, we use leaf mulch elsewhere because it is naturally occurring, native to the location, produces a lower carbon footprint and helps build mycorrhizal fungi which symbiotically partners with plants to provide a secondary root system and sustainable nutrition [1].

Of course, weeding continues, but now is an especially important time to remove aggressive weeds before they produce seeds. Some of the problematic plants that you may want to keep an eye out for in your garden are Pennsylvania smartweed, garlic mustard, stilt grass, chickweed, henbit and dead nettle. Concurrently, we are also collecting and storing the seeds of the plants we prefer—non-invasive natives—which we will propagate later this year or next. Recently, we have been planting perennials, red spruce and plants rescued from nearby High Hampton Resort . In our turf areas, we have been aerating and over-seeding as regular annual maintenance for overall turf health and enhancement. We also had our soils tested recently to identify needs for optimal turf health in the next growing season, carefully adhering to our organic protocol.

Our water mitigation efforts continue along with the rain, and we have focused on erosion prevention. After working with Sitework Studios and Robinson Associates Consulting Engineers last spring to research and develop best practices for water mitigation, we have begun implementing recommended landscape treatments. First, we mapped the sites, and then began ground truthing the water as it traveled across the Reserve. We are monitoring both sheet and channel flow of rain water during storms to evaluate varying storm intensities and the effects on our landscape. The modifications include adding hydra humps with rock outlets, adding turf and rock swales, and altering existing swales to better direct the water. We are also constructing step pools and rock check damns within the swales to control water velocity. Finally, we are experimenting with large woody debris (LWD) in a subwatershed to slow sheet-flow across the landscape and prevent valuable soil and nutrient loss.

mountain pond, wnc, gardens, gardening tips

If you have not yet tended to any of these tasks relevant for your home and garden, there is still time. In preparation for the coming winter, we have some seasonal suggestions:

  • Top dress trees, shrubs and perennials with a layer of composted or aged cow or horse manure. Doing this during the winter months enables the nutrients to stay in place longer and make their way down into the soil to the roots.
  • Prune deciduous trees and shrubs. You can better see the branching structure in the winter. Additionally, dormancy prevents tissue regeneration until spring, meaning the plant will not suffer from energy loss or sap flow.
  • Sow wildflower and other native plant seeds. This provides the cold period necessary for some seeds to germinate in the spring.
  • Plant spring flowering bulbs that will generate roots and come up in the spring.
  • Dig up dahlia roots after a frost or two and place them on top of mulch. Once the roots dry out, store them in peat moss inside cardboard boxes in a cool, dark location. They will be ready to replant in the spring after the last frost.
  • Transplant trees, shrubs and perennials to preferred locations. Transplanting while dormant keeps plants from going into shock.
  • Collect leaves from turf areas and move to wooded areas for compost. This is preferable to burning, which adds pollutants to the air and increases respiratory health issues.
  • Prevent snow from accumulating on evergreen trees and shrubs to avoid bending and breaking of branches.
  • Winterize any irrigation pipes that may be in danger of freezing.

German Forestry Society Visits Red Spruce Restoration Site

Posted Posted in SHR-News

Southern Highlands Reserve was honored to join the United States Forest Service (USFS) on Friday, October 5, to welcome 17 members of the German Forestry Society (GFS), led by Hans C. Rohr, to Flat Laurel in the Pisgah National Forest. The group included a wilderness researcher, high-ranking government forestry officials, and an advisor to German Prime Minister Angela Merkel on matters of the environment. This unprecedented visit stems from the origin of the USFS.

In 1888, George Washington Vanderbilt visited Asheville for relief from malaria-like symptoms. Captivated by the scenic beauty of the landscape, he purchased property and built the mansion later named Biltmore. Eventually owning more than 125,000 acres of forest, including virgin stands, Vanderbilt hired Fredrick Law Olmsted to design the estate grounds. Olmsted brought along Gifford Pinchot, one of the only two foresters in the U.S. at the time, who came to be known as the father of American forestry. Pisgah Forest was the first regularly managed forest with the goal of earning income from timber planted in areas left bare from fire, grazing and previous logging.

Pinchot recommended his successor, Dr. Carl A. Schenck, a German forester who opened the Biltmore School of Forestry in 1898. Congress later designated the school “The Cradle of Forestry” in America’s Forest Discovery Center, thereby establishing the first forestry school in the nation [1]. Over the past few decades, John C. Palmer, a now-retired Haywood Community College forestry professor, has been visiting Germany to learn more about Dr. Schenck. He established a relationship with Schenck’s descendants, as well as between the Society of American Foresters (SAF) and the GFS. A 2014 visit by the SAF to Germany led to this reciprocal visit by the GFS to see the birthplace of American forestry and learn about current USFS practices in the southern Appalachians and coastal plain.

Pisgah District Ranger Dave Casey led the talk, beginning with an overview of the district, stating that U.S. forests are prized as resources for recreation, and that over half of the district is not managed commercially while wilderness areas are not managed at all. Casey was joined by Rachel Dickson of the Pisgah Zone Silviculture Program, and the two explained that as public servants, the USFS has responded to the wishes of the public to make timber production less of a priority. Also, compared to those in the West, national forests in the eastern U.S. do not contribute a large volume to timber production. As such, current USFS efforts include restoration, driven by ecological motives to improve forest diversity and health.

Over the last century, spruce-fir forests have been greatly reduced across the southern Appalachians due to logging. Balds visible today are the result of severe fires 100 years ago followed by rains which washed away the seed and soil profile necessary for species regeneration, coupled with slow growth at the high elevation. Red spruce present today were planted in the 1940s as a restoration effort after those slash fires, with current restoration efforts still attempting to restore what was lost.

Red spruce was considered the best restoration candidate because it is the conifer species least in decline. Another motivating factor for choosing red spruce was to help the Carolina northern flying squirrel, a federally endangered species. This squirrel feeds on mycorrhizal fungi, or truffles, that grow at the roots of red spruce. Additionally, southern Carolina flying squirrels carry a harmful gut parasite that they pass along to northern Carolina flying squirrels at the boundary overlap. When eaten, the oil from red spruce needles suppresses that harmful gut parasite, protecting the health of the squirrels.

The Flat Laurel site was selected for a visit on the GFS tour to discuss red spruce restoration, illustrated by the 2017 planting of 900 red spruce under yellow birch across five acres. This year, USFS will girdle the overstory to gradually release the young red spruce trees from competition. This process involves strict parameters and will exclude deciduous trees under seven inches in caliper, yellow birch with exfoliating bark used by northern Carolina flying squirrels to build dreys (nests), and trees with cavities that can be used by the squirrels as dreys. In collaboration with the North Carolina Wildlife Resources Commission (NCWRC), the planting location was based on proximity to larger NCWRC lands, thereby producing stepping stones to more habitat.

As a founding member of the Southern Appalachian Spruce Restoration Initiative (SASRI), formed to restore red spruce and the vitality of spruce-fir forests in the Southern Appalachian Mountains, SHR Executive Director Kelly Holdbrooks discussed our support as propagator and provider of the young trees. Holdbrooks spoke to the group about our strategy for red spruce propagation to produce the highest possible success rates once planted in the wild. We’ve learned that planting fewer trees between three and four years of age is more successful than planting a larger quantity of plugs (younger trees). This way, the trees are tall and strong enough to survive abundant leaf-fall from deciduous hardwoods. Additionally, since no one is coming back to water after planting, it is important for these larger root balls to hold as much moisture as possible. Not only are these trees larger, they are also free from being rootbound because we grow them in specially designed Rootmaker pots.

Thanks to these propagation strategies, trees that survive the first year in the wild will most likely live a full lifespan of 350 years or more, barring natural disaster. One year after planting the 900 Flat Laurel trees, we estimate a mortality rate of less than 10%—an extremely successful conservation project. Dave Casey stated the USFS, “initially started restoration efforts by transplanting naturally regenerated seedlings which is unsustainable and drastically reduced their capacity to restore red spruce at a meaningful scale. Thanks to SHR—interwoven into our restoration efforts from planning, outreach, education and implementation—we are now making a meaningful impact together on red spruce restoration.”

How You Can Help Grow a Greener World

Posted Posted in SHR-News

Biodiversity refers to the diversity, or variety, of living organisms on the planet within a given ecosystem, as well as the variety of ecosystem types. This diversity is indispensable to the dynamic processes that keep ecosystems healthy. The wider the range of species, the more resilient an ecosystem is in the face of stress and disease. At the top of the food chain, humans depend on all beneath us, down to the insects necessary for crop pollination and even microorganisms with which we enjoy symbiotic relationships [1]. Ultimately, each species is of value because of the role that it plays within the greater whole. When a particular species is removed from the equation, its function is no longer performed, ultimately leading to benefits or detriments for other directly related species.A prime example is the introduction of Buddleia davidii, commonly known as butterfly bush, as it is often planted to attract butterflies. Though butterflies lay eggs on the shrub, it provides no nutrition for the hatched caterpillars which are then left to die. Native to Japan but naturalized in the United States with no animal species to keep it in check, this dense shrub spreads rapidly, prohibiting the growth of nutritious native species (e.g. milkweeds, violets, and asters).

A recent study estimated the extinction rate has increased a hundredfold over the last century, and humans seem to be responsible [1]. As we grow in number (the world population is expected to reach more than 10 billion by 2060) we use more resources, leaving fewer for other species. Over-hunting, poaching, pollution, fragmentation and loss of habitat, over-exploitation of biological resources, an increase in invasive species and climate change have all contributed to the rise of the extinction rate.

This sharp decline in biodiversity is affecting every region of the world, threatening the ability of people to find adequate food and clean drinking water, according to a United Nations report. “Earth is losing species at an unsustainable rate—more than 1,000 times the natural speed of evolution. We are losing not only certain species, but the populations of many species are declining [2].” The scale of impact is such that many scientists advocate defining this as a new geological epoch called the Anthropocene, named from anthropo for “man” because human-kind is causing these mass extinctions [3].

That said, how can each of us play a part in supporting biodiversity for the benefit not only of those other species, but also ourselves? Opportunities exist for involvement on many levels and the choice is, of course, up to each of us. However, it all starts with awareness. Once we become informed, we can then choose how best to become involved, depending on our individual circumstances and resources.

Of the many notable issues, one that stands out to us right now is the “Botany Bill” (HR1054 and S3240), introduced to the House of Representatives in February 2017. The bill is intended to promote botanical research and education to support the land management responsibilities of the Department of the Interior [4]. This includes research funding to develop effective approaches for habitat restoration and directly relates to our red spruce restoration work which is crucial to the survival of the federally endangered Carolina northern flying squirrel. If you would like to learn more about what you can do to promote this bill, visit see The Botany Bill’s How to Help page [5].

Many resources are available for you to become informed about critical environmental issues and legislation. You may already have your favorites, but if not, these websites can help you get started: and The Nature Conservancy. If you are just beginning the journey to become a part of the process, don’t get overwhelmed, but instead focus on what calls to you most. One of the things you can do in your daily life is reduce your carbon footprint—even small steps add up and changes in habit pay off exponentially over time. Much of what we have been told about being “green” is simply a marketing strategy, but a truly sustainable lifestyle comes from being intentional in small ways, daily. For example, keep a reusable, BPA-free water bottle with you instead of drinking disposable bottled water. Another important action you can take is speaking up; let your legislators and other key decision makers know what is important to you. Finally, our favorite way to make a difference is by planting native plants, which provide sustenance for native animals, thereby advancing the natural cycles of our ecosystem.

Gardener’s Corner with Director of Horticulture Eric Kimbrel

With its warm weather and long days, summer beckons us outside and into its fruits of full bloom. We have been adding to the abundance by planting perennials for more even color throughout the garden.

Another object of plenty has been rainfall. Few days have been without any, and many days have been filled with hard, soaking rains. One side effect is leaf gall (Exobasidium vaccinii) [1]—a fungal disease common to native Rhododendron species and Leucothoe, exacerbated by rain. We have spent much of the summer removing this pest before it spreads further. We have also been spraying Rhododendron buds with ecologically friendly horticultural oil to control leafhoppers which transmit bud blast—another fungal pathogen that kills the buds [2]. We continue to monitor our hemlocks for adult woolly adelgids, the non-native insects that are decimating the hemlock forests due to the lack of natural predator. We use dormant oil in this case as well to treat the pest, but we don’t stop there. Healthy trees are less susceptible to infestation, so we check the soil to see what may be at the root, so to speak, of the cause. And summer is always the season for pulling and spraying weeds.

In effort to help reduce our carbon footprint, we have been spreading wood chip mulch back into the woodlands and onto our trails. The natural process of decomposition does not occur when we remove deadwood and fallen branches from the landscape, so any additional that we can add back is a benefit.

With regards to the Core Park design, ground truthing for a new short trail from Rattlesnake Trail to the Nursery Complex is complete, and construction is soon to be underway. We are renovating the Sunken Garden by adding Perma Till to increase drainage within the walls, as well as adding more coneflowers. Phase two of the Vaseyi Trail boardwalk is soon to begin to help protect the delicate ecosystem through which it passes. Finally, ground truthing is in progress in preparation for water mitigation work that will take place over the fall and winter. We are flagging high priority areas needing to be addressed based on recent analysis from Sitework Studios and Robinson Engineering.

We recently hosted a tour for this year’s Cullowhee Native Plant Conference, and also attended conference workshops for continued education on all things native. One note of interest is that $43 billion per year is spent on the necessary control of invasive non-native species—more than is spent in disaster relief. Lecturer and author Claudia West spoke on the importance of using a small number of species within a single garden design for a distinct concept, thereby producing a stronger emotional response. Also, in this post-wild age, nature creates syngameons—groups of like species able to exchange genes indirectly and produce hybrids—as survival a technique.

Summer is also the season of seeds which we have been collecting for propagation—Trillium, Heuchera and others. Many of these will go back into the Reserve, while others will be available at the 2018 Native Plant Sale! It is scheduled for August 24 from 9 am to 3 pm. This is your opportunity to bring home some of the native plants featured in our gardens. We hope to see you there, and touring the gardens at summer’s end!
