Douglas-fir is one of the best known wood species in the world. In British Columbia there are two varieties of Douglas-fir, Coastal and Interior.

The Coastal variety occurs along the southern mainland Coast and across Vancouver Island, except for the very northern tip. The Interior variety is found throughout southern British Columbia, and as far north as the centre of the British Columbia Outdoor Wilderness Guide.

DOUGLAS FIR pseudotsuga menziesii. The Douglas Fir is also known as Coast Douglas-fir, Oregon Pine, Oregon Douglas-fir, Douglas Tree, Interior Douglas-fir ; This is not a fir at all but 'Pseudotsuga' or "False Hemlock"   British Columbia's Interior Forests British Columbia’s interior forests are the most vast in the province.

They stretch 1, kilometres ( miles) from the dry ponderosa pine forest in the south to the western red cedar and hemlock of the Columbia region to the spruce and pine boreal forest along the Yukon border. The interior region covers 80 million :// This study developed a stand table projection system for interior Douglas-fir (Pseudotsuga menziesii (Mirb.)Franco var.

In British Columbia, there are two varieties of Douglas-fir: Coastal and Interior. The sapwood is light in colour and of narrow width. The heartwood ranges from yellowish to reddish-brown. Earlywood and latewood have a pronounced difference in colour, the latewood having darker, more   Douglas-fir is one of Canada’s most highly valued trees, not only because it covers a wide range of ecosystems, but also because of its high-quality products.

Douglas-fir is processed into lumber, veneer products, interior and exterior finishing, and pulp. However, Douglas-fir faces a number of biological and climate-related stresses, including Armillaria and Phellinus root diseases, Douglas /natural-resistance-douglas-firs/   Subalpine fir (Abies lasiocarpa), also known as balsam or balsam fir, grows throughout most of the British Columbia Interior, and is marketed in the SPF species group (spruce-pine-fir) with lodgepole pine and interior ://   Douglas-fir is the dominant tree species, occurring in open savannah-like stands on drier sites with bluebunch wheatgrass and rough fescues forming the understory.

Wetter sites at higher elevations support dense stands of Douglas-fir with a pinegrass and feathermoss  › B.C. Home › Ministry of Environment › ESD. Bark: Douglas fir’s bark is a reddish-brown, fissured and corky.

Native to: From British Columbia to California. Uses: The Douglas fir is the major timber species in its native North America, and its imported timber is sold here as ‘Oregon pine’.

Originally grown in this country for ornamental purposes, it is now a valuable timber tree Common Douglas-fir is a deep-rooting species; however, as in many other tree species, its root morphology varies according to the nature of the soil.

In deep, well-drained soils, taproots may grow up to 50% of their final depth in 3 to 5 years. Plate-like root systems develop when it grows in shallow soils or with a high water :// /tree-species-compendium-index/douglas-fir.

The coast Douglas-fir variety is the dominant tree west of the Cascade Mountains in the Pacific Northwest, occurring in nearly all forest types, competes well on most parent materials, aspects, and slopes.

Adapted to a moist, mild climate, it grows larger and faster than Rocky Mountain :// Tree improvement and research into genetic variability of coastal Douglas-fir started in the late s with studies conducted by Dr.

From the rainforest to the boreal forest you'll see Douglas Fir, Pacific Dogwood, Garry Oak, Trembling Aspen, Lodgepole Pine, Yellow Cedar and   The most consistent tree species was western hemlock (Tsuga heterophylla), with lodgepole pine (Pinus contorta var. latifolia) and Douglas-fir (pseudotsuga menziesii var.

glauca) sometimes present. Shrub and herb species tended to have relatively low cover values, while moss cover was highly variable, ranging from 7 to 97%. Western hemlock is the single most plentiful tree species on the coast of British Columbia. It grows along both the east and west sides of the Coast Range, from sea level to mid–elevations, as well as in the Interior wet belt west of the Rocky Mountains.

On average it typically grows 30 to 50 metres tall and 1 to metres in diameter. It seldom grows in pure stands, and is The Tree and Stand Simulator (TASS) is a biologically based, spatially explicit, individual tree TASS brochure (PDF, MB) provides a brief overview.
