Silvicultural Treatment Opportunities 



Often a stand of timber has two or more treatment opportunities avail- 

 able, so the acreage of that stand is applied to each of those opportunities. 

 Commercial timberland acreage by treatment class, shown in Table 43, gives 

 the total number of acres categorized as having a particular treatment oppor- 

 tunity. There are six treatment classes that indicate that no immediate 

 treatment opportunities are available. Those classes are: harvest - low risk; 

 two-storied stand (overstory, harvest - low risk; understory, manageable); 

 no treatment due to productive condition; no treatment - inoperable; no 

 treatment - deferred until merchantable; and unknown - poor crowns, good 

 growth. 



The most common treatment class on sampled land in Beaverhead County 

 was harvest - high risk, followed closely by harvest - low risk, and no 

 treatment due to productive condition. If the treatment classes that indicate 

 that immediate treatment opportunities are available are ignored, about 55 

 percent of the sampled commercial timberland in Beaverhead County had 

 treatment opportunities available. 



In Broadwater County, the most common treatment classes were precom- 

 mercial thinning, regeneration of understocked areas, and overstory removal. 

 About 85 percent of the sampled commercial timberland had treatment oppor- 

 tunities. 



Harvest - high risk was the most common treatment class in Deer Lodge 

 County, followed by harvest-low risk and no treatment due to productive 

 condition. There were treatment opportunities available on 57 percent of the 

 sampled commercial timberland. 



In Granite County, harvest - high risk and overstory removal were tied 

 for the leading treatment class. Precommercial thinning and harvest - low 

 risk were the next most common. Treatment opportunities were available on 

 72 percent of the sampled timberland. 



The most common treatment classes in Jefferson County were precommer- 

 cial thinning, regeneration of understocked areas, overstory removal, and 

 sanitation. There were treatment opportunities on 80 percent of the sampled 

 timberland.
