DISTRIBUTION AND OCCURRENCE
SPECIES: Abies magnifica | California Red Fir 



GENERAL DISTRIBUTION : 
California red fir occurs in the Sierra Nevada from Kern County,
California, north to the southern Cascade Range of Oregon and in the
Coast Ranges from Lake County, California, north to the Klamath Ranges
[43,46,49,54].  California red fir is also found in extreme western
Nevada [46].

Shasta red fir occurs in the southern Sierra Nevada and in the Klamath
Ranges, Siskiyou Mountains and the Cascade Range of northern California
and southern Oregon [1,25,28].

HABITAT TYPES AND PLANT COMMUNITIES : 
California red fir occurs in pure, dense forests between the lower
montane white fir (Abies concolor) or mixed-conifer forests and the
upper montane or subalpine lodgepole pine (Pinus contorta var. murryana)
and mountain hemlock (Tsuga mertensiana) forests [5,6,7,54,68].  In the
upper montane coniferous forests, California red fir is an overstory
dominant on mesic sites [5,6].  Canopies can be open or closed, and
understory vegetation is variable but generally sparse [54,55].

California red fir or Shasta red fir is listed as overstory dominants in
the following published classifications:

Preliminary plant associations of the southern Oregon Cascade Mountain
  Province [2]
