How do fir trees adapt to their environment?

Another reason these fir trees survive the cold is these needles are rather thick. This means that there is less transpiration than usual leaves. Because of the extreme cold, they have adapted by growing tall and straight instead of having branches that spread out so that they can conserve their energy.

Is white fir shade tolerant?

Growth: Once established, white fir grows best in full sun [178]. Shade-tolerant white fir saplings can, however, endure decades of suppression under a closed canopy or in dense brushfields.

Is white fir the same as Douglas fir?

White firs have small cones that are rather plain looking. These cones are generally in clusters at the tops of the trees. Douglas-firs have little projections that come out of the pine cones and are slightly larger. Botanists say that the cones have a long tridentine bract that protrudes prominently above each scale.

Is white fir fire resistant?

White firs also act as a “fire ladder” because of their resinous foliage and retention of their lower limbs. They become a sort of incendiary device, allowing flames to reach up to the canopy, thinning out large pine stands that might otherwise escape smaller forest fires.

What are the adaptations of coniferous trees?

Adaptations of vegetation. Coniferous trees have thick bark to protect against the cold. They are cone-shaped, with flexible branches which help them to cope with heavy snow fall. Pine cones protect the seeds during the harsh winter.

How fast does white fir?

Growth Rate This tree grows at a slow to medium rate, with height increases of anywhere from less than 12″ to 24″ per year.

What is the most shade tolerant tree?

What is white fir good for?

White fir wood is light in weight and is manufactured primarily into lumber, plywood for construction and industrial use, and wood pulp for paper manufacture. Construction uses include framing, sheathing, concrete forms, roof deck- ing, and siding.

Is White Fir strong?

White Fir ranks with the several important softwoods of similar weight and density in bending strength, compression and stiffness. Volumetric shrinkage of wood is 4.9 percent when dried from a green state to 12-15 percent moisture content, or about midway in the 3.4-6.6 range of all softwoods.

Is white fir strong?

How long do white fir live?

300 years
White fir live over 300 years and naturally occur at an elevation between 900–3,400 m (2,950–11,200 ft). It is popular as an ornamental landscaping tree and as a Christmas tree. The specific epithet concolor means “all one color”.

What kind of sun does a white fir tree need?

Full sun and partial shade are best for this tree, meaning it prefers a minimum of four hours of direct, unfiltered sunlight each day. The white fir grows in acidic, loamy, moist, sandy and well-drained soils. It prefers normal moisture but has moderate drought tolerance.

How are white fir trees adapted to fire?

FIRE ECOLOGY OR ADAPTATIONS: Fire regimes: White fir occurs in a variety of forest and habitat types that evolved with a variety of fire regimes. Thin-barked and resin blistered, with drooping lower branches, young white fir is highly susceptible to fire, and mature trees are only moderately fire tolerant.

What kind of root structure does a fir tree have?

Fir trees are equipped with special root structures, called adventitious roots, which grow directly from their trunks to help keep them anchored on steep mountain slopes and resist strong pressure from blowing winds. Fir trees also have thick bark that is nearly twice as thick as the bark of many other trees.

What’s the life span of a Douglas fir tree?

Basic Facts about the Douglas-fir Tree The lifespan of a Douglas-Fir Tree is anywhere from 500 to 1,000 years. The Douglas-Fir is also known as the Douglas Spruce or the Oregon Pine tree. Many animals in the temperate rainforest feed off of the needles of the tree.
