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.

S2The primary purpose of this paper is not only to report the results of a comparative analysis as to how well the Q.I. method predicts log product values when compared to commercial sawmill log output values, but also to develop a methodology which will facilitate the comparison and provide the adjustments needed by the sawmill operator. The commercial sawlog values as derived in an independent study of seven sawmills in southeastern Ohio and eastern Kentucky were compared with Q.I. values developed for an analysis of log and tree valuation. (Whittaker and McCauley 1966). Six different species were compared: red oak, black oak, scarlet oak, white oak, chestnut oak, and yellow-poplar.S3.
