Lodgepole pine - Stands in which lodgepole pine constitutes 50 

 percent or more of the total net cubic volume. The minimum vol- 

 ume for a sawtimber stand is generally 3 thousand board feet per 

 acre . 



Western redcedar - Stands in which western redcedar constitutes 

 50 percent or more of the total net cubic volume. The minimum 

 volume for a sawtimber stand is generally 4 thousand board feet 

 per acre or 8 cedar ooles per acre. 



Cedar-grand fir - Stands in which western redcedar and grand fir, 

 either separately or combined, constitute 50 percent or more of 

 the total net cubic volume. The minimum volume for a sawtimber 

 stand is generally 4 thousand board feet per acre or 8 cedar poles 

 per acre. 



Cottonwood - Stands in which northern black Cottonwood constitutes 

 50 percent or more of the total net cubic volume. The minimum 

 volume for a sawtimber stand is generally 4 thousand board feet 

 per acre. 



Commercial stands are also grouped into 3 classes according to size 

 of trees predominating. These are: 



Sawtimber stands - Stands in which a plurality of the total net 

 cubic volume is in trees of sawtimber size and that generally 

 average 3 or 4 thousand board feet of sawtimber volume per acre, 

 excluding cedar poles. White pine, ponderosa pine, lodgepole 

 pine, western redcedar, and cottonwood trees 11.0 inches in diam- 

 eter and larger at breast height are classed as sawtimber. For 

 the other species, trees 13.0 inches and larger are classed as 

 sawtimber . 



Pole stands - Stands in which a plurality of the total net cubic 

 volume is in trees from 5.0 inches in diameter to sawtimber size. 



Seedling-sapling stands - Stands in which a plurality of the 

 total net cubic volume is in trees less than 5.0 inches in diam- 

 eter . 



Nonstocked Commercial Forest Land 



Nonstocked cutover - Unimproved, logged areas which at the date of 

 mapping generally averaged less than 3 or 4 thousand board feet 

 per acre, and less than 10 percent stocked with poles and/or seed- 

 lings and saplings.
