Betula alleghaniensis is the provincial tree of Quebec, where it is commonly called merisier, a name which in France is used for the wild cherry.Betula alleghaniensis (yellow birch, also known as golden birch), is a large and important lumber species of birch native to North-eastern North America. The name "yellow birch" reflects the color of the tree's bark. The name Betula lutea was used expansively for this tree but has now been replaced.

It is a medium-sized, typically single stemmed, deciduous tree reaching 60-80 feet (18-24m) tall (exceptionally to 100ft (30m)) with a trunk typically 2-3ft (0.61-0.91m) in diameter. Yellow birch is a relatively long lived birch which typically grows 150 years and may even grow up to 300 in old growth forests.
It mostly reproduces by seed. Mature trees typically start producing seeds at about 40 years but may start as young as 20. The optimum age for seed production is about 70 years. Good seed crops are not produced every year, and tend to be produced in intervals of 1-4 years with the years between good years having little seed production. The seeds germinate best on mossy logs, decaying wood or cracks in boulders since they cannot penetrate the leaf litter layer. Yellow birch saplings will not establish in full shade (under a closed canopy) so they typically need disturbances in a forest in order to establish and grow.
Both yellow, and sweet birch have nearly identical leaf shape and both give and odor of wintergreen when crushed. To differentiate the two species the range, buds, or bark must be examined. The ranges do overlap in Appalachia where they commonly grow together, but black birch does not grow west of Ohio or north into Canada whereas yellow birch does. Black also has black non-peeling bark compared to the lighter, bronze colored, peeling bark of yellow birch. For young trees where bark has not yet developed, yellow birch can also be identified by its has hairy buds and stems; sweet birch has hairless buds.
Two varieties have been recognized
Its native range extends from Newfoundland to Prince Edward Island, Nova Scotia, New Brunswick, southern Quebec and Ontario, and the southeast corner of Manitoba in Canada, west to Minnesota, and south in the Appalachian Mountains to northern Georgia. While its range extends as far south as Georgia, it is most abundant in the northern part of its range and only occurs in high elevations in the southern part of the range. It grows in USDA zones 3-7.
B. alleghaniensis prefers to grow in cooler conditions and is often found on north facing slopes, swamps, stream banks, and rich woods. It does not grow well in dry regions or regions with hot summers. It grows soil pH ranging from 4-8.
The twigs are browsed on by whitetail deer, moose and cottontails Deer eat many saplings and may limit regeneration of the species if the deer population is too great.Ruffed grouse and various songbirds feed on the seeds and buds. Due to the thin bark of the tree yellow bellied sapsuckers feed on this tree by drilling holes in the tree and collecting the sap.Broad-winged hawks show a preference for nesting in yellow birch in New York.
Several species of Lepidoptera including the mourning cloak (Nymphalis antiopa) and dreamy duskywing (Erynnis icelus) feed on B. alleghaniensis as caterpillars.
Yellow birch is often associated with eastern hemlock throughout its range due to their similar preferences in habitat. It mostly grows from 0-500 m in elevation but may grow up to 1000 m. It reaches its maximum importance in the transition zone between low elevation deciduous forests and high elevation spruce and fir forests. Due to the thin bark and lack of ability to resprout, it is easily killed by wildfire.
Sugar maple (Acer saccharum) exerts allelopathic effects on seedlings of yellow birch and decreases their growth ability. The inhibitory chemical is exuded from the roots of the sugar maple and has a very short soil half-life, it no longer has effects on birch after 5 days.
Yellow birch is considered the most important species birch for lumber and important hardwood timber tree; as such the wood of Betula alleghaniensis is extensively used for flooring, furniture, doors, veneer,cabinetry and toothpicks. Most wood sold as birch in North America is from this tree. Its wood is relatively strong, close grained, and heavy. The wood varies in color from reddish brown to creamy white and accepts stain and can be worked to a high polish.
In the past, yellow birch has been used to distilling wood alcohol, acetate of lime and for tar and oils. Oil of wintergreen can be distilled from the bark.
The papery, shredded bark, is very flammable and can be peeled off and used as a fire starter even in wet conditions.
Yellow birch has been used medicinally by Native Americans as a blood purifier and as other uses.
Yellow birch can be tapped for syrup similarly to sugar maple although the sap has less sugar content, it flows in greater quantity than sugar maple. When the sap is boiled down the wintergreen evaporates and leaves a syrup not unlike maple syrup. The sap can also be used as is in birch syrup or may be flavored. Tea can also be made from the twigs and inner bark.
