Characterization of the Pulpwood Procurement Environment of Northwest Louisiana With a Geographic Information System.

An analysis of the pulpwood procurement environment was made to describe and model forest land area, ownership patterns, timber production, forest inventory, and the transportation network of 13 parishes in the northwest region . of Louisiana. Pulpwood delivered to a pulpmill accounts for approximately 50 percent of pulp production costs. The cost of delivered pulpwood is a function of the mode of transportation, distance from the mill, competition for stumpage, and quality of the transportation network. A data base is developed from wood usage requirements, pulpmill and wood concentrat ion yard locations, location of forested areas and their relative volumes. Areas of potential sources of pulpwood stumpage were developed via procurement zones around each of the wood procurement centers in this region. Three major problems addressed in this study were 1) the effects of zone overlap and wood supply percentage at various delivery points, 2) locations of competitively void areas that would support future wood yards, and 3) relocations of wood concentration yards. Output of the analysis was in the form of maps and descriptive statistics from the GIS database. Various scenarios were modeled by manipulating relocations of woodyards from areas of high competition to areas of lesser competition.
