Sawlimber of Rather Poor Qiialily 



Softwoods make up 40 percent of the total saw- 

 timber volume in the State, but vary from 59 percent 

 in the northeastern division to 3 percent in the south- 

 eastern and 5 percent in the western divisions (table 9). 

 Most of the sawtimber volume is in trees of relatively 

 small diameter (table 10). When used for lumber 

 such trees yield mainly common grades.

\\ ith respect to hardwoods, more of the volume is 

 in the larger trees. However, Minnesota is on the 

 western fringe of the natural range of the maple- 

 beech-birch type, and tree development is poor. Its 

 oak forests, especially those of the savannah type along 

 the prairie edge, support trees that are short, crooked, 

 and limby (fig. 16). Its best quality hardwoods are 

 on lowlands and coves adjacent to the Mississippi 

 River and its tributaries. 



Recent studies indicate that for the entire State, 67 

 percent of the merchantable hardwood sawtimber vol- 

 ume is in No. 3 or tie-and-timbcr log grade, mainly 

 suitable for manufacture into box and crate material, 

 pallets, dunnage, timbers, and rough lumber. Log 

 grades No. 1 and No. 2, fit for sawing into standard 

 lumber and other more specialized uses, make uji the 

 remaining 33 percent of the volume.
