Pseudotsuga menziesii (Douglas-fir), Pinaceae 

Thank you! I appreciate the feedback.

Nice. Need to try make a flute some time

Thank you for your comment. My pronunciation may have been influenced by my travels. I agree that Douglas-fir would make a wonderful Native American style flute. I had a friend from the Confederated Tribes of Warm Springs who carved a couple of beautiful flutes that I love playing, although he primarily used western redcedar which has a warm tone. I would love to carve my own flutes.

@@MHCCDendrology You can do it, Pualani! Get out there and carve some flutes! I'm sure that your Native friend will help you and teach you how to do it.

The spacing for this species depends on site conditions and land management objectives. In this part of Oregon, Douglas-fir are often planted on a 10' x 10' spacing or 435 TPA (trees per acre), or 11'x11' or 12'x12' spacing. Then usually at around 12-16 years of age, you might opt to precommercial thin (PCT). However, spacing depends very much on the objectives including ecology, forest health, wildlife value, aesthetics, economics, etc. Douglas-fir typically will grow to 5-7 feet in diameter but can grow up to about 15' in diameter. If you are considering planting them in your yard, keep in mind that they can grow up to 250 ft tall.

Douglas-fir is generally considered shade intolerant. Young trees are moderately tolerant of shade, but mature trees love sunlight.
