AcknowledgementsThis Update required help from a group of dedicated individuals. Henry Spelter (FPL) updated the product demand relations; Ken Skog (FPL) updated the fuelwood projections, Peter Ince (FPL) provided the various fiber demands for the pulp sector; Robert Phelps (WO) helped with projections of the macroeconomic variables and determinants of end use activity; Bill Luppold (NE) revised hardwood lumber production and trade data; Tom Farrenkopf (PNW), Joanne Faulkner (SO), John Kelly (SO), Ray Sheffield (SE), and Sharon Woudenberg (IN) provided PIA inventory data for updating the ATLAS input decks. Jonna Kincaid (University of Washington) and Eric Jensen (University of Montana) provided outstanding programming assistance. Finally, Judy Mikowski (PNW) helped assemble input files, complied various output summaries, and provided valuable assistance in preparing this draft.

Timber products output and timber harvests in Alaska: an addendum

“…The RPA timber assessments (Haynes et al 2007) provide the background for the many assumptions needed in the demand model. The size of the U.S. market 15 This is done using a set of conversion factors that equate wood in its different product forms to actual wood fiber content.…”

“…Major sources of information have always been the RPA timber assessment updates (Haynes et al 2007) that provide information on U.S. consumption, Once the model is updated for use, the challenge is the preparation of the demand scenarios. These are developed based on our collective views and interpretation of what might happen given the current situation and trends.…”

“…Within the typology of forest sector models, the Brooks and Haynes model is a variant of the gap model format in that it explicitly considers only physical quantities and does not directly consider prices and costs. This model is a commonly accepted form of a forest sector model and was used in the RPA assessments through 1980 (Adams and Haynes 2007, Haynes 1993. It satisfies economic principles in that production equals consumption (with adjustments for trade).…”

“…This approach is consistent with planning methods used in business and government communities where the intent is to help organizations cope with unexpected future events (Schwartz 1991(Schwartz , 2003. Here we have assumed that there will be an increase in global demand for forest products (Haynes et al 2007, UNECE 2006. This demand will be for both traditional solid and fiber products.…”

“…Colloquially, these are called the RPA timber assessments. The highlights of the most recent RPA timber assessment (Haynes et al 2007) are summarized in the appendix. The first RPA timber assessment, published in 1982, introduced more rigorous economic modeling methods than previous analyses of the timber situations conducted by the Forest Service.…”
