  • The Rhythm of the Land

    by Nicolette L. Cagle, July 22, 2026, Sennett’s Hole, Durham, NC The air is thick with the reverberations of cricket frogs that clatter, katydids that creak, and birds that burr. Between the pulsing choruses and punctuated calls, the river chatters, babbling over boulders and burbling through descending levels of metamorphic rock. A gentle wind pushes…

  • What Happens to a Nut on the Forest Floor?

    by Nicolette L. Cagle, June 1, 2026 What happens to a hickory nut or walnut after it falls to the forest floor? At first, it can seem like a simple thing, a stored future released from the canopy and left beneath the tree that made it. Imagine a hickory nut resting inside its husk, a…

  • Silver Birch: A Tree of Disturbance and Renewal

    by Nicolette L. Cagle, Ph.D., April 13, 2026 In the last several posts, I’ve explored the dry woodlands and steppe-edge habitats of Central Europe, where trees grow in bright light and on poor soils impacted by disturbance. After turning to Scots Pine, I arrive at another characteristic species of these transitional places: Silver Birch (Betula…

  • Scots Pine: The Workhorse of Dry European Soils

    by Nicolette L. Cagle, Ph.D., April 13, 2026 In the last post, I explored the dry woodlands and steppe-edge habitats of Central Europe, where thin soils, lots of light, and anthropogenic disturbance create a different world from the cool mountain forests, broadleaf lowlands, and floodplains that came before. Here, I turn to one of the…

  • Rock, Loess, and Light: Dry Woodlands and Steppe-Edge Habitats of Central Europe

    by Nicolette L. Cagle, Ph.D., April 13, 2026 In the last several posts, I’ve been moving through the major forested worlds of Central Europe, from mountain forests of Spruce, Fir, Beech, and Larch, to the Broadleaf Forests of the lowlands and foothills, and most recently to the shifting floodplain forests of the Danube, Morava, and…

  • Pannonian Ash: A Tree of Hardwood Gallery Forests and Lowland Rivers

    by Nicolette L. Cagle, Ph.D., April 13, 2026 In the last several posts, I’ve been exploring the floodplain forests of Central Europe through some of their characteristic trees, including Black Alder and Black Poplar, both species closely tied to shifting sediments and mercurial river banks. Pannonian Ash belongs to the floodplain as well, but it…

  • Black Poplar: The Fast-Growing Pioneer of Central Europe’s Floodplains

    by Nicolette L. Cagle, Ph.D., April 13, 2026 In recent posts, I have been exploring the dynamic floodplain forests found along the iconic Danube, Morava, and Tisza Rivers, including the resilient, rooted, and red-hued Black Alder. But Black Alder is not alone in its ability to live with instability. It is joined by Black Poplar,…

  • Black Alder: The Rooted, Red Tree of Central Europe’s Floodplain Forests

    by Nicolette L. Cagle, Ph.D., April 12, 2026 In the last post, I introduced another forested ecosystem in the Central European tree series: the dynamic floodplain forests found along the iconic Danube, Morava, and Tisza Rivers. These systems are home to survivors, plants that stand firm in shifting sands and along muddy banks, including the…

  • European Hornbeam: Knitting the Broadleaf Forest Across Moisture Regimes and Canopy Layers

    by Nicolette L. Cagle, Ph.D., April 4, 2026 In the last two posts, I introduced two species that anchor the mesic and upland Broadleaf Forests of Central Europe: Pedunculate Oak and Sessile Oak. Here, I turn to a species that helps knit those forest stands together across moisture regimes and canopy layers: European Hornbeam. If…

  • Fruiting Fungi & Woody Plants in the Piedmont

    When we explore the Piedmont woods, our attention sometimes shifts away from the showy flowers, stately trees, and singing birds to the diminutive mushrooms around us. Many of these mushrooms have key and important associations with the woody plants that so often structure our definitions of ecosystems.  Fungi & Oaks. In the Piedmont, there are…

  • Fringetree

    This week’s plant feature is the fringetree (Chionanthus virginicus), also known as old man’s beard because of the way its pretty, white petals droop when it blooms in April.

  • Origins of the Word “Haw”

    Today, the term “haw” refers specifically to the red pome (i.e., the indehiscent fruit containing multiple seeds) of the hawthorn (Crataegus species). However, the common name “hawthorn” is derived from the Old English word “haga,” meaning hedge. The common names of possumhaw (Ilex decidua), blackhaw (Viburnum rafinesquianum), rusty blackhaw (Viburnum rufidulum), and possumhaw viburnum (Viburnum…

  • American Beech

    “[The] Beech is identifiable by the gleam of its wondrously smooth bark, not furrowed even by extreme old age. Here it will be free of branches for full half its height, the sturdy boughs then gracefully down-sweeping. The gray bole has a further beauty in the way it flutes out at the base into strong…

  • GREAT EXPECTATIONS: February in the Piedmont

    BirdsIn 1936, writer and naturalist Donald Culross Peattie opined that “February is a good month in which to make friends with the birds of a great city.” In North Carolina, he may be right: winter still holds steady in February, and the bird community changes more slowly than it will later in spring. Some of…

  • GREAT EXPECTATIONS: January in the Piedmont

    BirdsIn the depth of winter, as you walk through quiet woods, you may come across a lone thrush standing at attention, its delicately speckled throat exposed. The Hermit Thrush is a gifted songster, but its voice is mostly muted here; it saves its ethereal song for spring, when it returns to its breeding grounds in…

  • Crowders Mountain State Park (Kings Mountain, North Carolina)

    The forest floor was littered with fallen leaves—some big and brown like the finely lobed leaves of chestnut oaks, others bright red like the cheery leaves of red maples. We hiked up and up, past car-sized boulders encrusted with bright green lichens. As the slope steepened, the ridge-top forest thinned and tightened: Virginia pines grew…
