Prince William Forest Park is the largest contiguous piedmont forest type in the National Park Service.  The park sits in a transitional zone between northern and southern climates, and eastern and western physiographic provinces. On your journey through the park's 15,000 acres you will find several rare communities, including a seepage swamp, remote stands of eastern hemlock, and several populations of rare plants. As surveys are conducted, other rare communities may be located.

From the top of the forest canopy to the bottom of Quantico Creek, forest ecosystems act as entire communities, much like cities do for humans. Different animals and insect use the various 'stories' for the forest high rise for different reasons. Understory trees and vegetation, including dogwood, redbud, ironwood, mountain laurel, American holly, solomon's seal, spotted wintergreen, and sassafras, are found throughout the forest. Ferns, mosses, vines, briers, and numerous wildflowers form the groundcover. Cardinal flower and hercules club are common in the park, although uncommon and protected elsewhere.

White Pine, Pinus strobus
The White Pine is easiest to identify by the five needles in each vesicle. An easy way to remember is white five letters so there are five needles in every white pine bundle. During colonial times white pines were marked with arrows, these were designated as king trees, which were to be used for the royal navy for building sails. Early lumber tree because it can float on water which makes it easy to transport

White Oak, Quercus alba
This is a large growing tree which dominates the forest canopy. This tree like many oaks is a great wildlife species. The acorns are a favorite to many wildlife species even early settlers would boil and eaten or grounded into a flower. White oak is a favorite of early and modern loggers for the constriction of houses. White oak was used in the construction of the cabin camps which are in the park.

Yellow Poplar, Liriodendron tulipifera
Yellow Poplar also goes by the name “Tulip Tree” since its leaves resemble that of a tulip. Yellow Poplars are the tallest growing tree in the eastern United States.  Its size and light weight of the wood combined with the straightness of the trunk makes this tree ideal for wood working. The wood is easy to work with and was used by American Indians for canoes.

           

Red Maple, Acer rubrum
Now one of the most dominate trees in the eastern united states because of the absence of forest fires in today’s forests.  Red maples are easy to identify because of the
characteristic smooth park and the leaves which during the fall turn bright red.  During the winter when the leaves are gone the tree is still easy to spot with its opposite branching (M.A.D) Maple, Ash, and Dogwood are the three species which have opposite branching

Virginia Pine, Pinus virginiana
One of the most common species in Prince William Forest Park. Virginia Pine is easy to identify its flaky bark, and two needles in a bundle is direct give away. It is a pioneer species and is the first tree to enter a sight enriching the soil and making it possible for others to grow. When the Cabin Branch Pyrite mine was found to be contaminated and not allowing anything to grow at the site the National Park Service planted 5,00 Virginia Pines in hopes of bringing the site bake to its original setting

Sassafras, Sassafras albidum
The roots and bark supply oil for perfume soap and sassafras tea, and have been used to flavor root bear. It was believed that the bark also acted as a cure-all for diseases. But resent research has found the roots and bark of the sassafras to have cancerous properties.

American Beech, Fagus grandifolia
The American beech is easy to identify because of the engravings written in them which gives the tree its second name known as the “graffiti tree”. Daniel Boone left his mark in a Beech tree while hunting writing "D. Boone Cilled A bar ON Tree In Year 1760". Throughout Prince William Forest Park you'll see many such writings on trees. Please do not leave your mark on a beech tree. They are beautiful just the way they are and carvings into trees can be a venue for disease and parasites to enter and eventually kill the tree.

The smooth bark of the beech tree can be compared to elephant skin and the leaves, which turn a bright yellow in fall, eventually brown and remain on the tree until spring.

Mountain Laurel, Kalmia latifolia
Mountain laurel is poisonous to several different animals, including horses, goats, cattle, sheep, and deer. The honey which is made from mountain laurel pollen is believed to be poisonous. The wood has been used to make tool handles and tobacco pipes.

American Chestnut, Castanea dentata
Chestnuts were picked and soled commercially to venders in New York. Commercial pickers looked for an easier way to pick these chestnuts and found the Chinese chestnut which is native to Asia which is a small growing tree which allows for easy picking. The first Chinese Chestnut tree was brought to New York City; the Chinese Chestnuts brought a decease known as the Chinese chestnut blight which American chestnuts are not resistant to. This blight has completely obliterated the population of American Chestnuts. Look through the park and you may find a sapling or two which has not yet been attacked.

Low Bush Blueberry, Vaccinium angustifolium
This small shrub is common through out the park. Low Bush Blueberry is fire-tolerant and its numbers often increase in an area following a forest fire. These wild blueberries are edible just like commercially grown.
