These observations together suggest that Douglas-fir
clippings provided by Red Squirrels are very likely to serve as a winter food source for Mule Deer in some areas.
The company also tested rooted cutting technologies in Douglas-fir
and loblolly pine and reached the same conclusion.
Composition, function, and structure of old-growth Douglas-fir
is not considered a primary host for P.
and the southern yellow pines are resinous softwoods that exhibit abrupt transition from earlywood growth to latewood growth within a given growth ring and large density differences between earlywood to latewood regions.
For the 2015 study, Douglas-fir
and southern pine crossarms were selected from mill run stock and graded at two different wholesale manufacturers, one in Louisiana and the other in South Carolina.
(Pseudotsuga menziesii), ponderosa pine (Pinus ponderosa), and northern red oak (Quercus rubra) lumber was cut into clear samples measuring 25 by 75 by 127 mm long.
AMERICAN FORESTS is partnering with the Nez Perce Tribe to plant 137,000 ponderosa pine and Douglas-fir
seedlings over 450 acres.
The main interior structure was made using Oregon sourced, Douglas-fir
glued laminated (glulam) beams which serve as ribs and louvers.
It's also home to eight huge national champs: Western redcedar, 931 pts.; Sitka spruce, 883 pts.; Coast Douglas-fir
, 809 pts.; Alaska-cedar, 588 pts.; Western hemlock, 3 co-champs, 549, 528, 523 pts.; Pacific silver fir, 487 pts.
