Though humans have a long history of building with wood, it was only recently that we brought standardization to trees, regardless of their species or significance.
Sawmills appraise the value of a standing tree by the number of eight, twelve, or sixteen-foot segments it can produce. While a 90-year-old Eastern white pine would sell for $1200 due to its great potential to be converted into dimensional lumber, a curvy cherry of the same age may be deemed valueless and only suitable for pulps.
