Duck Lakes Basin, my first stop, was near the eastern margin of that mountainous heap, four ranges removed from the damp ocean airmass, but also perched at the apex of a topographic "V" that funnels northerly weather straight in to nurture those sneaky subalpine firs
Zhang and Cai (2011) estimated moisture gradients during high-temperature drying of subalpine fir
(Abies lasiocarpa) through microscopic analysis.
The combination of these variables with either slope or thermal aspect accounted for the distribution of willow, subalpine fir
, mountain mahogany, and antelope bitterbrush in proximity to forest cover.
Using high-elevation forests in Yellowstone National Park as the proxy HRV for Wyoming high-elevation national forests composed of lodgepole pine, subalpine fir
, and Engelmann spruce, the percent of area burned on the landscape was outside the HRV for the Bighorn National Forest, a forest with moderate levels of timber harvest.
and mountain hemlock, for example, can attain ages of about 300 and 900 years, respectively.
At the base of a subalpine fir
, backed by two rocks and shielded in the front by a screen of small yews, two kittens intertwine as if fighting in slow motion.
Douglas-fir, western larch, and subalpine fir
have also increased substantially over the years, from 1 percent or less in 1976 to about 5 percent each in 1998.
However, subalpine fir
and small ([less than]10 cm dbh) Engelmann spruce largely escape the effects of spruce beetle outbreak, thereby dramatically changing the composition of the infested stand (Schmid and Hinds 1974, Baker and Veblen 1990, Holsten et al.
respectively) and we could detect the introgression with interior subalpine fir
in addition, there is within the sale area an unestimated volume of subalpine fir
sawtimber, douglas-fir sawtimber, engelmann spruce - other sawtimber, lodgepole pine sawtimber, and ponderosa pine sawtimber that the bidder may agree to remove at a fixed rate.
Additionally, Englemann spruce and subalpine fir
, growing at high altitude, are unpredictably tall, but can we convert these colorful, though inexact, adjectives and adverbs to tough-love numbers?
The Bingham fires are burning in patchy, subalpine fir
and lodgepole pine, with plenty of dead and fallen trees and accumulations of flammable debris on the ground.
In Vancouver, one western spruce board without field-cut treatment, two subalpine fir
(Abies lasiocarpa) boards, one with field-cut treatment and one without, one balsam fir field-cut treated board, and one ponderosa pine (Pinus ponderosa) board without field-cut treatment were rated 7.
Owl sites were found to be more likely to occur closer to streams and to be rare in the Subalpine Fir
(Abies lasiocarpa) vegetation type.

(Abies lasiocarpa), and seral lodgepole pine stands.
