Trees that are large enough and of high enough quality to produce logs that can be sawed into lumber. To estimate volume in sawtimber trees using Table 1, trees should have at least a 10-inch DBH and a minimum diameter inside the bark at the top of the log that is the larger of either 8 inches or 50 percent of tree DBH.
Standing trees of an appropriate size (for example, 13 inches DBH and above) and species to be used to produce lumber. Logs cut from sawtimber trees are called sawlogs. Also see “Chip- n-saw,” “Diameter breast high,” “Merchantable timber,” “Pulpwood,' and “Veneer log.'
