The wood products industry for many years had the luxury of having a low cost, seemingly endless supply of raw material. Because of this there was little incentive to make better use of the forest through higher yields or use of low grade logs. Emphasis was aimed at maximizing productivity and minimizing production costs without much regard to how well the raw material was utilized.
