At the time of the survey, habitat types had not been described for the area outside of 

 northern Idaho. The data are summarized by climax tree species: 



Douglas-fir, 

 Grand fir. 

 Western redcedar. 

 Western hemlock, . 

 Mountain hemlock, 

 Subalpine fir. 



Pseudotsuga menziesii var. glauea (Beissn.) Franco 



Abies grandis (Dougl.) Lindl. 



Thuja plicata Donn. 



Tsuga heterophylla (Raf.) Sarg. 



Tsuga mertensiana (Bong.) Carr. 



Abies lasiocarpa (Hook.) Nutt. 



The study area was divided into four geographic areas: 



Geographic area 



1- -Northern Idaho and 



western Montana 



2 - -Central Montana and 



eastern Idaho 



3- -Southwestern Montana 



and central Idaho 



4- -Utah 



National Forests sampled 

 Clearwater, Coeur d'Alene, Colville, Flathead, Kaniksu 

 Kootenai, Lolo, Nezperce, and St. Joe. 

 Caribou, Gallatin, and Lewis and Clark 



Beaverhead, Bitterroot, Boise, Challis, Deerlodge, Payette, 

 Salmon, and Sawtooth 



Ashley, Cache, Dixie, Fishlake, Manti-LaSal, and Wasatch 



Stocking sometimes varies for habitats with the same climax species when they are 

 located in different geographic areas. For instance, on subalpine fir habitats in 

 areas 1 and 3 (table 1), plantation stocking is nearly double that on subalpine fir 

 habitats in areas 2 and 4. Stocking also varied for grand fir habitats; area 1 had 

 twice the stocking of planted trees as area 3. Much of this diversity might have been 

 explained by different habitat types if a classification system had been available 

 that used understory vegetation criteria to further subdivide the range in environmental 

 conditions for all areas.
