Accurate estimation of forest biomass to enable the mapping of forest C stocks over large areas is of considerable interest nowadays. Airborne laser scanning (ALS) systems bring a new perspective to forest inventories and subsequent biomass estimation. The objective of this research was to combine growth models used to update old inventory data to a reference year, low-density ALS data, and k. Douglas fir, genus of about six species of evergreen trees of the conifer family Pinaceae, native to western North America and eastern Asia. They are important timber trees and produce strong wood. Several are grown as ornamentals and are common Christmas trees in North America.

Timber Sale Query The Department of Natural Resources' (DNR's) Timber Sale Web Search Application helps prospective purchasers identify state timber sales that meet their needs. The timeframe for the tool is the current month plus the next two months. This query tool allows the user to look at timber sale specifics such as: the DNR Region in which the sale or sales are. As a logger and harvester of standing timber, there are several factors to consider when determining the standing timber prices you will pay. You first need to determine the costs of harvesting your logs. If you have been logging for a year or more, all you need to do is look over your books .

Timber Products: Douglas Fir Products graded for Structural and Appearance applications. If you are looking for the best in structural timber, the first choice is Douglas Fir. It has an excellent strength to weight ratio and the highest rating of any western softwood for extreme fiber stress in bending.
Botanical name: Pseudotsuga menziesii. Other common names: Douglas-fir, Oregon. Strength: Douglas-fir is an excellent framing timber. Durability: Douglas-fir heartwood is rated as Class 3 durability and can be used for above-ground purposes, but the sapwood is timber cannot be pressure treated with copper, chromium and arsenic (CCA), but can be boron treated to.
This is a tree from the Pacific Northwest where the climate demands a heavier, harder and stronger timber than an interior grown tree. There is a reason to request coastal lumber.
The heartwood is a light reddish brown, maturing to a rich orange-red. This is fast becoming the architects’ darling. The approx. density is 33 lbs/ Range: $ - $ Douglas Fir has a high bending strength, shear strength and stiffness. It is a hard species and is suitable for use where wear is a factor.
The heartwood is moderately decay resistant. This softwood lumber dries well with good dimensional stability. Douglas-Fir is technically not a true Fir (Abies genus), but is in its own genus: Pseudotsuga.
The tree itself grows to be very large, and yields a large amount of usable lumber and veneer for plywood. It is an incredibly valuable commercial timber, widely used in construction and building purposes. Douglas-fir (Pseudotsuga menziesii) is one of the world’s best-known and most widely used wood species.
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.
Rough Sawn Douglas Fir Timbers. All douglas fir orders must be placed ahead of time, In stock orders take 3 - 10 days to produce All of our timbers are stocked as or resawn from graded and stamped #1 Structural, and are all FOHC (Free of Heart Centers).
We have a sawmill on site so we can cut to any specifications. *denotes custom size, not. Douglas-fir; Fir; Larch; Coast Redwood; Hemlock; Sugi; Kauri; Softwood trees account for nearly 80% of the world’s production of timber.
Most softwood trees have needles and/or do not have broad leaves. Softwood trees tend to grow much faster than hardwood trees, which makes them a very plentiful source of timber.
Intelligent craftsmanship is our passion. All materials created on site have a home, meaning % utilization. Our softwood veneer helps produce our award-winning hardwood plywood, while chips and sawdust make up our quality particle leftovers.
The sapwood is generally narrow usually less than 50mm wide and lighter in colour than the heartwood which is light reddish-brown in colour. The abrupt change and contrast in colour between early-wood and late-wood bands, produce a prominent growth ring figure.
The timber has an orangey-pink hue, maturing to a deeper orange over time, giving it a distinctive feel and flavour. Douglas fir performs best in straight frames.
Due to a lower moisture content Douglas fir seasons more quickly than hardwood, so can take surface finishes to bring out its natural character. For ages, the finest builders, carpenters and craftsman alike have relied on Douglas Fir for its superior strength, exceptional work-ability and overall attractive appearance.
Our Kiln Dried Timbers are dried and handled with the same care and attention to quality as all our specialty products. Third, the value of timber depends heavily on how much timber is sold in one timber sale and what kind of harvesting is done.
Often, the larger the sale, the higher the price per unit of wood that can be offered. It can be more costly per unit of wood removed to cut only a few, selected trees, rather than cut most or all trees in the stand.

Douglas Fir Regarded as one of the strongest and most durable soft wood materials, Douglas Fir has always been the preferred choice of builders, engineers and architects.
Popular for its light rosy color, excellent strength-to-weight ratio and for being dimensionally stable, it's able to provide superior nail-holding capabilities.
Douglas Fir is one of the most widely used species for framing due to its strength, dimensional stability and its availability. The most common framing grade is #2 and the most common uses are for rafters, joists, studs and posts.
