2 Based on the total commercial forest area in the owner- 

 ship. 



3 The operating area of an individual ownership is the 

 combined area of the forest types, within the ownership, 

 in which some cutting was done since January 1, 1947. 



The operating area of any size class or type of ownership 

 is the sum of the operating areas on individual ownerships 

 in that size class or type of ownership. Excludes operating 

 area on some large private ownerships on which access was 

 denied. 



^ Less than 0.5 percent. 



proportion of recenth* cut land in the upper 

 productivity class. On ownerships of 100 acres 

 or less, which include one-third of all private com- 

 mercial forest land in the Nation, only 38 percent 

 of recently cut lands fell in the upper productivity 

 class. All small ownerships combined (less than 

 5,000 acres) comprise 74 percent of all private 

 forest land and over half of all private and public 

 combined. In this group, only 40 percent of 



recently cut lands qualify for the upper produc- 

 tivitjr class (fig. 80). 



The situation is much .more favorable on the 

 larger private ownerships. For those of the 

 medium size class (5,000-50,000 acres), 64 percent 

 of the recently cut lands qualified in the upper 

 productivity' class. For large ownerships (50,000 

 acres and larger), 78 percent of recently cut lands 

 were found to be in this upper productivity class.
