Fir is subject to windthrow, especially on shallow wet soils. Because of its thin bark, shallow root system, and flammable needles, balsam fir is easily killed by fire. Balsam fir is distributed throughout the Northeast and upper Midwest. For a current distribution map, please consult the Plant Profile page for this speciesFile Size: KB.
Balsam fir is native to the far northern parts of the United States, up into Canada. This evergreen tree has flat, dark green needles with a strong balsam scent. Balsam fir makes a striking figure in the landscape with its narrowly-pyramidal shape, but it does best in cooler northern climates. The Balsam Fir (Abies balsamea) is a small to medium-sized tree widespread in moist woodlands and swamps in boreal forests of the its range it may also be referred to as Balsam, Canadian Balsam, Canada Balsam, Eastern Fir, and Bracted Balsam Fir. It is the provincial tree of New Brunswick.
Balsam Fir Abies balsamea. The balsam fir is a native evergreen well-adapted to the cold climates of the northern United States and Canada. Its symmetrical spire-like crown, shining dark green color, and spicy fragrance have made it a favorite Christmas tree for hundreds of years. The branches are also popular in holiday wreaths and other greenery.

The estimates of total foliage weight on a branch and the proportion of each age of foliage were combined to estimate the weight of foliage for each age on a given branch.

Balsam fir wood is soft, limber, light in weight, low in bending and compressive strength, and low in abil-ity to resist shock. It shrinks only moderately in drying and is easy to season, but is low in nail-holding ability.
Balsam fir has a density of pounds per cubic foot at a moisture content of 15 percent. PRINCIPAL USES. Patterns of shoot numbers, shoot length, needle length, and foliage weight were examined throughout a spruce budworm (Choristoneura fumiferana (Clem.)) outbreak cycle, for young balsam fir (Abies balsamea (L.) Mill.), representing four spacing and defoliation conditions.

Introduction. A tree crown can be regarded as an integrated complex of shoots, linked together to form a hierarchy that varies both in time and space (White, ).Knowledge of the vertical distribution of foliage in a tree crown is particularly important when assessing the amount of light received by the foliage and, thus, the resulting rate of total photosynthesis (Verhagen et al., ).Cited by: Chemical analysis of balsam fir browse during the growing season varied according to color as follows: (percent composition on dry matter basis) foliage color protein fat fiber ash N-free Mg K Extract very yellow yellow light green 1.
Manipulative field studies were carried out to evaluate the foliage age preference–performance relationship for an extreme generalist herbivore, the whitemarked tussock moth (Orygia leucostigma Smith) (Lepidoptera: Lymantriidae), within balsam fir [Abies balsamea (L.)

balsameasit upright on the branches and are 2 to 4 inches long. Like most firs, the bracts are shorter than the scales. Often covered with resinous blisters, the bark of young trees is gray and smooth turning more reddish brown and scaly with age.
46 BALSAM FIR B F Abies balsamea (L.) P. Mill. B alsam fir occurs statewide and is the most abundant tree in the state. It is frequently found in damp woods and on well-drained hillsides, and often occurs in thickets. The tree normally forms a sharp spire to a height of 60–70 feet and grows to 12–20 inches in young.
Balsam fir is a small to medium-size evergreen tree typically 14–20 metres (46–66 ft) tall, occasionally reaching a height of 27 metres (89 ft). The narrow conic crown consists of dense, dark-green : Pinaceae.
Comments: Balsam Fir is a favorite Christmas tree species, and its resin is used to make Canada balsam. Such resin (when purified) has very good optical qualities, and was used as an adhesive in bonding optical elements and lenses up until the s, when it was replaced by synthetic resins.
Average annual mortality of balsam fir was about million cubic feet from to (chart on right). This rate has increased 33% since but fallen since Balsam fir makes up % of total volume statewide but 2% of allFile Size: 1MB.Balsam fir is truly a northern species and is an important part of northern mixed forests or boreal forests.
As I’ve already told you, Abies balsamea is an incredibly important wildlife tree. Deer, moose, rabbits, and many species of birds use balsam fir stands for thermal cover because the dense foliage cuts down on wind and insulates the area.Balsam fir grows from sea level to within 15 to 23 m (50 to 75 ft) below the m (6, ft) summit of Mount Washington in the White Mountains of New Hampshire.
