' The determination of size class of private ownership was based on the total 

 commercial forest land area in the ownership. The operating area of an in- 

 dividual ownership is the combined area of the forest types, within the owner- 

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



area of any size class or type of o%vnership is the sum of the operating areas on 

 individual ownerships in that size class or type of ownership. Productivity 

 is expressed as a percentage of operating area found to be in a high, medium 

 or low productivity class.
