Forest habitat type is an important characteristic in evaluating management needs 

 and productivity of the forest. The mature lodgepole pine stands included in this study 

 are primarily in the alpine fir habitat types. Several other individual habitat types 

 are also represented, but because there were relatively few samples in each, data were 

 combined by major habitat series. The habitat types and areas are as follows:

Alpine fir/(series) 



(Menziesia and Clintonia phases)
