Available Supplies A'ot Fully Utilized 



THE QUANTITY of wood harvested in 1953 

 amounted to only about half the material 

 theoretically available for cutting (fig. 44, table 31). 

 The theoretical allowable cut, of course, includes all 

 operable stands ready for harvesting regardless of 

 location, species composition, or log grade. The 

 cut in 1953 also amounted to only one-third of the 

 net annual growth of sawtimber and 40 percent of 

 the growth of growing stock.

Some Hardwoods Overabundant 



Outstanding examples of incomplete utilization 

 are in aspen, paper birch, ash, and elm (table 32). 

 In some localities in the north, even maple and bass- 

 wood show an excess supply. Generally, however, 

 the good grades of hardwood sawtimber — especially of 

 yellow birch, basswood, oak, collonwood, and 

 walnut — are used more fully than is desirable. In 

 these species the need for additional cutting is either 

 in remote localities or in trees with a large proportion 

 of low-grade logs. 



All of the principal pulp species show some margin 

 of surplus over actual 1953 cut for the State (table 33). 



Significantly, the surplus pine and spruce is confined 

 to the relatively inaccessible Superior District.
