Data indicates that the largest 

 discrepancies between the current 

 covertype distribution and historic 

 data are that there is currently 

 less lodgepole pine and more mixed- 

 conifer covertypes. Currently, the 



largest discrepancies between 

 appropriate covertype and current 

 covertype appear to be that there 

 are more mixed-conifer and subalpine 

 fir (24 percent) covertype and less 

 western larch/Douglas-fir covertypes 

 (22 percent) . Increases in the 

 subalpine fir and mixed-conifer 

 covertypes may be a consequence of 

 an increase in shade-tolerant 

 species from fire suppression and 

 past harvesting that selectively 

 removed some of the shade -intolerant 

 species. Current covertype 

 distribution is displayed in TABLE 

 C-1 - CURRENT COVERTYPE DISTRIBUTION 

 WITHIN PROPOSED HARVEST UNITS.

AGE -CLASS DISTRIBUTION 



FIGURE C-2-COMPARISON OF CURRENT 

 AGE-CLASS DISTRIBUTIION IN THE 

 ANALYSIS AREA AND AGE -CLASS 

 DISTRIBUTION FROM HISTORIC UPPER 

 FLATHEAD VALLEY DATA provides a 

 comparison of the current age-class 

 distribution in the analysis area 

 and from Historic Upper Flathead 

 Valley data. 



State ownership in the analysis area 

 has approximately 25 percent less 

 area in the seedling/sapling age 

 class (0 to 39 years) and 11 percent 

 more area in the old-stand age class 

 than Historic Data over the larger 

 climatic section. TABLE C-2 - 

 CURRENT AGE-CLASS DISTRIBUTION IN 

 THE PROPOSED HARVEST UNITS is 

 displayed below.
