Calculate the merchantable volume of a log using the International 1/4, Doyle or Scribner Log Rules.
Calculate the green weight of this log using the green combined weight of wood and bark in lbs/cf value for the species you are calculating for. If you know the green weight value of wood and bark use your value. If you don't know this value see if the species you are calculating for is listed in the list below.
The values in the list below are taken from:

(Patrick D. Miles, W. Brad Smith)
Keep in mind that the values provided in the list are average values for green weight of bark and wood at certain moisture content. The actual weight value could be higher or lower depending on moisture content of the log.
