In Maine, statewide biomass estimates have increased from 752 million dry tons in 1982 to 980 million dry tons in a 2003 estimate. These estimates are produced using Forest Inventory & Analysis (FIA) data collected during Maine’s periodic and now annualized inventory design. The Maine Forest Service began tracking and reporting on wood flows of biomass in 1986. For the last 20 years (1986–2005) the total annual harvesting of all products has ranged between 6 and 7 million cords, extracted from a standing inventory that is currently estimated to be 277 million cords. The objectives of this current study were (1) to document historic estimates of forest biomass; (2) to outline the current estimation process; and (3) to estimate availability of various forest- and tree-based biomass components at a variety of scales. This analysis uses a variety of data including previously published reports, current Maine Forest Service wood processor reports, and the latest USDA Forest Service Forest Inventory and Analysis (FIA) data.
