Grading is complex. An experienced forester can give an accurate appraisal. A board foot is 144 cubic inches of useable wood that can be cut out of a log . Sawlogs are divided into four sides for grading purposes, starting with the one containing the most defects. The second worst side determines the grade.
Prices can vary widely with markets and location.
Chipwood is used for paper and panel products and brings a lower price than sawtimber. Chipwood comes mostly from loblolly pine and low quality hardwoods. Chipwood is measured in cords or tons .
