A study of logging utilization in Montana during 2002 provided logging and product utilization data for sawlog and veneer log harvests in Montana. Results of the study indicate a shift toward greater utilization of smaller diameter material, as 78 percent of the harvested volume in Montana during 2002 came from trees less than 17 inches diameter at breast height. The portion of inventory volume utilized is also increasing, as indicated by decreasing removals factors for growing stock (1.081 cubic feet removed from inventory per cubic foot delivered to the mill) and sawtimber trees (0.961 cubic feet removed per cubic foot delivered to the mill). The study also provided factors for converting volumes to and from Scribner and International 1/4-inch rule log scales, as well as to and from cubic foot volumes.

An estimated 466 million ft 3 of forest residue material (nonmerchantable, 3 inches diameter and larger) is generated annually in the Northern Rocky Mountains (Montana, Idaho, Wyoming). Extensive studies of residues in the major forest types show a considerable portion is suited for various products. The lodgepole pine type has the greatest potential for increased residue utilization. In most other forest types, form and condition of residues limit potential use to fiber or fuel. In all forest types, volume, condition, and product potential vary widely from stand to stand.
