Is Douglas fir fast growing?
Tall, Taller, Tallest A cultivated tree never achieves the same height or grandeur. In your yard, a Douglas fir will only grow 40 to 60 feet tall. Experts at Cal Poly estimate the growth rate of Douglas fir at 24 inches a year, but this also depends on its growing conditions.
How big is the biggest Douglas fir?
327 feet
After more than a century of logging around it, the world’s tallest known Douglas fir still stands 327 feet in a remote part of east-central Coos County. The Doerner Fir was measured with great accuracy by a team of two climbers from Ascending the Giants of Portland, who climbed to the top of the tree in 2008.
How tall is the Coast Douglas Fir?
250 feet tall
Coast Douglas fir (Pseudotsuga menziesii var. menziesii) – which grows in wet, coastal and inland areas from California up into Canada. This variety can grow up to 250 feet tall and reach 5-6 feet in diameter.
Is Douglas fir harder than oak?
Oak scores higher on other qualities related to strength as well, including modulus of rupture, elastic modulus and crushing strength. It’s not inaccurate to say that oak is stronger than Douglas-fir as well as being harder. Oak is also denser, and it shrinks less.
How old is the oldest Douglas fir?
The oldest Douglas fir has been growing at least since A.D. 1320, said Ed Wright, now a postdoctoral research associate with the UA Laboratory of Tree-Ring Research, who discovered the old trees four years ago.
How long do Douglas fir trees last?
The largest coast Douglas firs commonly live to be at least 500 years and sometimes exceed 1,000 years. Rocky Mountain Douglas firs have a shorter lifespan, usually living no more than 400 years. The population of these trees is stable.
Is Douglas fir the strongest wood?
Douglas Fir is the strongest and thus most durable softwood you can rely upon.
How deep do Douglas fir roots go?
The root system depth in Douglas fir is determined pri- marily by the soil structure and texture. On perme- able soils with favourable moisture conditions, the roots may reach down to 60–100 cm but they may penetrate even deeper (Hermann 2005).
