Popis:	Equations that predict the dimension lumber grade yield from yellow-poplar trees (Liriodendron tulipfera L.) and sawlogs that are manufactured into 2 x 4's using the Saw-Dry-Rip system are presented. These equations require the measurement of dbh and merchantable height measured to an 8-in. top diameter. To predict the dimension lumber yield from yellow-poplar logs, a grading system that incorporates limiting defects with the clear-face concept used in southern pine log grading is utilized to stratify the logs. Once the logs have been graded, scaling diameter is used to predict the dimension lumber yield.
