  * For existing inventories - If you have a previously developed timber inventory and if you have access to the individual tree data collected during the inventory, these data could be entered in the biomass calculator to obtain biomass estimates for your property. The forester who conducted your inventory may have a copy of your raw field data.

• * Roadside costs are derived from a biomass harvesting study conducted by Purdue University and a logging contractor.
• * Revenue estimates are based on a low and high timber quality value for a lump-sum sale of standing trees.
