' 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 areaof the forest types, within theowner- 

 ship, 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. Productivity 

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

 or low productivity class.
