Utilization of the Eastern Hardwood Resource by the Hardwood Sawmilling Industry [PDF]

open access: yesNorthern Journal of Applied Forestry, 2001
Abstract The eastern hardwood resource contains numerous species that differ in grain, color, texture, and workability. Because the value of hardwoods is derived from appearance, these variations in physical attributes can cause the price for identical grades of hardwood lumber to vary by as much as 600% between species.
