Longleaf Pine is an iconic tree of the southeastern coastal plains, much as the Redwood and Sequoia trees dominate their respective regions of the West. It is hard to get a sense of the Longleaf Pine’s historical ecologic and economic importance as one passes through the fields, pine plantations, and forests of the southeast today, as it is eerily absent from most of its former habitat. Longleaf once covered 90 million acres with a range stretching from southeastern Virginia to south Florida and west to Eastern Texas. Longleaf Pine forests are estimated to cover only 2% of the land they formerly grew in, a sobering loss that many ecologists rank among one of the largest ecosystem declines worldwide.

Where did it all go? The first European people brought their livestock and set them free in the forests to forage. Hogs are especially hard on pines, eating the roots and leaves, but also disturbing the ground with their rooting, upending tender saplings in their wake. After the larger threats of habitat fragmentation and fire suppression, feral hogs still remain a detriment to the health of the remaining longleaf forests.

The trees were tapped and cut to produce pitch, tar, and turpentine for caulking ships and waterproofing canvas sails.  The southeastern Longleaf Pine forests were responsible for producing 70% of the world’s supply of naval stores (pitch, tar, and turpentine) in the early twentieth century. Finally, the large expanse of old growth Longleaf Pine was cut for its lumber around the same time. Its forests were replanted with faster growing species of pines for the pulp industry, and their habitat largely replaced with fields for cows, roads, cities, agriculture, etc. For more on longleaf history.

Longleaf Pine is quite an adaptable tree, growing in wetlands and dry sandy soil alike. Its scientific name is Pinus palustris:  palustris, derives from Latin, signifying marshy or swampy. Many people erroneously believe that Longleaf Pine only grows in the dry sandhills; it is often confined to these poorer soils because the land with richer or moister soil has been appropriated for agriculture or development. Longleaf Pine is considered a keystone species with hundreds of species of animals and plants dependant on its health, such as the gopher tortoise and red-cockaded woodpecker. Longleaf plant communities are especially diverse, with an understory of plants especially adapted to frequent fires and nutrient-poor, dry soil. The plant diversity in the understory of Longleaf Pine savannahs is staggering; when biologists count plant species per square meter, the Longleaf Pine ecosystems are among some of the most diverse in North America-- 95 plant species per 100 square meters.

Many Longleaf Pine communities historically experienced frequent fires, typically every two to five years, and in some instances annual fires were commonplace. In areas where frequent fires burn up the fallen wood and flammables the fires are less intense and tend to remain ground fires, rather than catastrophic raging fire rising to the canopy (as found in forests that use fire suppression). In addition to the common lightening storm-generated fires of spring and summer, Native people actively set fires to clear agricultural areas, increase browsing for game, and keep tick and chigger populations down. Fire suppression is one of the biggest challenges to the fire-adapted communities of the southeast. Many plants need fire to release seeds or to germinate, and many fire-adapted plants are quickly replaced with faster growing plants when fire is suppressed. People have been putting out forest fires to protect human communities and activities, and only in the past few decades has there been increased public awareness of the role of fire in healthy southeastern forests.

Longleaf Pine forests are not just fire adapted, they actually need fires to flourish and persist. If fire is suppressed, other faster growing species of pine will begin to dominate. Over time evergreen hardwood trees begin to creep in as well, shading out the understory and ultimately preventing longleaf seedlings from reaching the canopy. Fire clears out the understory and allows the Longleaf Pine seeds to fall unimpeded to the forest floor, with the sunlight and open ground necessary for germination. Longleaf Pines release their seeds in the fall, when the danger of fire is the lowest. After they germinate it is a race against time to grow large enough to survive a ground fire. While other pines invest energy in quick upward growth, longleaf has a more complex, slower strategy, evolved over millennia in response to the frequent fires of the southeast. Young longleaf saplings hug the ground in a tight cluster of needles, foregoing aerial growth for the development of a deep taproot, which often reaches 8 feet deep in less than a year. This low pattern of growth is called the grass stage, as the young sapling does indeed resemble a clump of wiregrass in the first part of its life. The grass stage typically lasts two to five years (up to 12 years); during this time the tree is garnering resources in its long taproot and accessing groundwater, which is a rare resource in the land of porous sandy soil.

If a fire blows through when a tree is in the grass stage, its tight needles are able to protect the growing terminal bud from permanent damage; even if the needles are scorched, the bud is able to produce a new generation of fresh green growth. After the tree has grown a sufficient taproot, it sprouts quickly in one season, above the danger of a low ground fire. It then begins to invest energy in the thick insulating bark typical of pines, which will continue to protect it from fire’s harm for hundreds of years.

This important tree, with its unique ecology, has become a priority for many land management agencies and private landowners. Prescribed burning (planned intentional fire) is fanning the health of these ancient forests. The presence of federally endangered animals, such as the red-cockaded woodpecker, is also giving the forests some protection. Its largest threat is the burgeoning human population of the southeast with its industries of pulp, cows, agriculture, etc. As the public gains a greater understanding of the natural history of the longleaf forests, we can hope to see its resurgence through increased planting and prescribed burning. It is a joy to lie under the dappled shade of longleaf pine on a soft bed of fallen bronze needles, gazing up at the swaying green canopy interspersed with bright blue sky, and lulled by the swishing sound of the wind playing in the treetops. It is my dream that these forests keep getting bigger, with the trees living to a ripe old age, dying from causes that have nothing to do with humans.

If you are interested in learning more about this fascinating tree, I recommend the book Looking for Longleaf by Lawrence Earley. Following is a poetic excerpt from the book: “The land of the longleaf pine is a land of great beauty but also of great violence, born from an encroaching sea and shaped by rivers, storm, and fire. It carries the evidence of immensities of time spent beneath ocean waters; the shells of sea creatures lie thick in the soil. Past seas shaped this land’s terrain, rivers its very pitch and roll. It’s a green land, year also a land of flame and ash. It was this region of sand and sea, wind and fire that longleaf flourished as no other pine could do, perfectly adapted to the conditions, swaggering over the Coastal Plain from southeastern Virginia to eastern Texas.”

    This is my first time coming across this but I’m finding out so much about these beautiful trees. Can anyone help me find out they were used medicinally? Thank you in advance! By the way.. this is my first blog experience here. 🙂

  2. I grew up in eastern NC and I just took the funky, interesting long-leaf pine for granted. Now I mourn how so many have been lost. However, ironically our military bases are decent long-leaf pine preserves, and more and more landowners are planting long-leaf pines. It’s heartening to see.

  3. Thank you very much for this lovely and informative post.I reside amongst the long leafed pines and do not even have curtains in windows, as their needles touch the glass and each day a new bird comes to visit.Today there were two bluebirds which was a rarity.The controlled burns have begun and further inland the logging trucks carve deep ruts in and out of the woods.I so love this majestic yet gentle tree.Their forest floor provides elegant needles for our baskets.

    Good work once again, Juliet. I’ve been fortunate to spend much of my life where natural environments still exist (the Arctic, Interior Alaska, the Olympic Peninsula) and some time there they have been radically altered. The difference on al levels is dramatic.

    Fascinating history! I grew up in Louisiana near Kisatchie National Forest which has a significant longleaf pine stand. Thank you for reminding me of home. I could almost smell the trees as I read.
    Great to see you at the Herb Fest!

  6. Juliet — thank you for writing this beautiful blog post! I am a big fan of yours and a friend of Mary Morgaine’s… Of course, I am deeply grateful for what you both bring to this world 😉

    My partner Phillip and I were JUST talking about whether the East/Southeast was ‘tended to’ by the Natives using fire. We recently read a great article called 1491 (will dig up the author)…and I recently read a review of a book on this topic focused on California (Tending the Wild: Native American Knowledge and the Management of California’s Natural Resources by Anderson). While driving through NE Georgia we started contemplating whether this ecosystem, too, was fire managed.

    Reading about the long-leaf pine has cleared my understanding up a bit. I am still curious about the plant communities around this tree, though! I will have to read the book you suggested.

    I was raised in Mississippi, by the way. Almost all land is either developed, logged or growing quick-growing pines for pulp. Because the pulp industry has slacked off quite a bit with the downturn in the economy many people are sitting on ’empty’ investments. Sadly, land — when it creates a determinable and controlled product of scale — is the way most people go. Folks don’t realize that a diverse and healthy ecosystem is the most valuable.

    The town I was raised in — Louisville, MS — was home to the last great giant pine. It’s name was “Old Boss” and you can find an image of it through a google search. It was revered and not cut. However, when it was struck my lightening and died…they special-ordered a saw to cut it down.

    Many people in Louisville have allergies that are pine related. My mother is also allergic to pine. To me, there are energetic ramifications of the mono-cropping of a tree and treating it like a commodity.

    Again, I appreciate this blog entry and am happy to continue my journey in understanding the more balanced true nature of the SE habitat (and how to live with it in balance).
