HABITAT TYPES AND PLANT COMMUNITIES : 
Pacific silver fir commonly occurs in late seral or climax mixed-conifer
stands [52].  Throughout its range the most commonly associated conifer
is western hemlock (Tsuga heterophylla).  Pacific silver fir also
reportedly grows in extensive pure stands in parts of the southern
Washington Cascade Range [14].  Below are publications in which Pacific
silver fir is listed as a dominant or codominant species:

Preliminary plant associations of the southern Oregon Cascade Province [9]
Preliminary classification of forest communities in the central portion
  of the western Cascades in Oregon [16]

Plant association of Mount Hood and Willamette National Forests of Oregon [35]
Forest communities of northern California [55]
Plant associations for the western hemlock zone [64]
