A total of logs from two species, red oak (Quercus rubra) and yellow poplar (Liriodendron tulip(/era), were measured in five typical hardwood sawmills across West Virginia to evaluate log sawing practices and lumber recovery. Log characteristics such as length, diameter, sweep, taper, and ellipticality were measured in sawmills, while log.
