The wood has a slight rosy cast; the sapwood generally a light straw color and the heartwood a deep russet brown. Main Uses. Its appearance is prized for joinery, panelling, cabinets, flooring, windows and cladding.

Motivations for intensive management of Douglas-fir in the nonindustrial private sector. Economic considerations for forest land management: one economist's view of U.S.
public ownership. Cost-benefit analysis of growing coast Douglas-fir in British Columbia. Douglas-fir accounts for 27 % of the growing stock and the Douglas-fir forest type is 28% of the acreage for all forest types (Van Hooser and Green ).
The ecological range of interior Douglas-fir is impressive. It occurs in a wide variety of environments except those that are too hot and dry and those at or near high elevation.
Pseudotsuga menziesii is an evergreen conifer species in the pine family, is native to western North America and is known as Douglas fir, Douglas-fir, Oregon pine, and Columbian pine.
There are three varieties: coast Douglas-fir (P. menziesii var. menziesii), Rocky Mountain Douglas-fir (P. menziesii var. glauca) and Mexican Douglas fir (P. menziesii var. lindleyana).Family: Pinaceae. WOOD PRODUCTS VALUE: Coast Douglas-fir is one of the worlds best timber producers and yields more timber than any other tree in North America [5,19].The wood is used for dimensional lumber, timbers, pilings, and plywood .Creosote-soaked pilings and decking are used in marine structures .The wood is also made into railroad ties, mine timbers, house logs, posts and.
The Douglas Fir has characteristics of many species of trees as is pointed out in The Sibley Guide to Trees, including spruces, firs and hemlocks. In fact the name Pseudotsuga means false hemlock.
It’s named after one of the most famous explorers of this region, David Douglas, whom in addition to the Douglas Fir, has his name attached to. to a high degree of Douglas fir, most stands being over 80 per cent, and 'many per cent, of this species. This is due to the abilitv of Douglas fir to establish itself by natural means more successfully than any of its associates in open areas following fire or logging.

A second suggested difference between the stand initia-tions of currently old versus young stands concerns the ini-tial spacing of Douglas-fir.
Establishment Adaptation: Douglas-fir needs excellent drainage. In the higher elevations of the West that receive snow and in the lower foothills that have moderately cold winters and hot summers, Douglas-fir requires moderate summer watering, generally times per month depending upon the absorption rate and water retention capacity of the soil.
Douglas fir growing west of the Cascade Crest to the Pacific Ocean in the states of Washington, Oregon, and northern California is known as coastal Douglas fir; identified by DF in the grade stamp. East of the Cascade Crest in the northern “Inland Empire” region, Western Larch (Larix occidentalis) grows intermixed with Douglas Size: 1MB.

Poor plantation establishment has been attributed to poor stock quality and severe grass and shrub competition for soil moisture. Innovative brushing methods are needed for the establishment of Douglas-fir on these dry sites. The data used in this study were collected from a dominant industrial Douglas fir stand in the Pacific Northwest (Washington State).
The site was selected based on logistics (location, and crew willingness to be studied) and the number of log-types being cut. Net stocked area of the stand was ha, with an average stocking of stems/ha. Douglas fir trees, Pseudotsuga menziesii, vary greatly in their self-fertility, but little is known about the relationship of self-fertility to outcrossing success.
Douglas-Fir Forests Disturbances occur over a range of spatial scales, from coarse (thousands of acres) to fine (less than 1 tree height in width). Coarse- and fine-scale distur-bances have affected the establishment, development, and at times destruction of unmanaged Douglas-fir forests.
