In some embodiments, the disclosure includes method for optimizing lumber derived from a log. The method may include the steps of debarking the log and cutting the log to provide a plurality of boards. The plurality of boards are then scanned to determine knot properties and/or warp stability for each of the plurality of boards and a lumber upgrade process is selected based on the knot properties and/or warp stability. Finally, one or more of the plurality of boards are planed after being subjected to the lumber upgrade process.
