Abstract
Largest crown width (LCW) equations for stand-grown trees were developed for 14 tree species found in western Oregon. The equations are used in the growth-and-yield model ORGANON and in the stand-visualization program VIZ4ST. They were constructed such that LCW equals the maximum crown width
of open-grown trees when the crown ratio is equal to one. Tree measurements needed for the equations are diameter at breast
height (in.), total tree height (ft), and crown length (ft)
