註釋

S2If we are to meet the increasing demand for lumber through more intensive forest management and increased utilization, we must find ways to economically process the low-grade segment of our sawtimber resource. We now have little or no information about the conversion value of sub-factory class sawlogs. The study reported here is the first step in determining the value of the sub-factory class of red oak sawlogs. If we assume similar red oak yields for any particular area of operation, the results reported should enable a sawmill operator to determine the marginal log for his particular operation if he knows his costs for converting these logs into factory-grade lumber.
