This dataset is based on information collected by mill data managers in Forest Inventory and Analysis (FIA) Units as well as collaborators in the Texas Forest Service, the Forest Products Laboratory (FPL), and the Focused Science Delivery Program of the Pacific Northwest Research Station (details below). The data describe wood-demanding mills of the continental United States. Data is restricted to primary wood processors-those that purchase logs or chips. Secondary processors of wood, such as paper mills that buy market pulp or rely entirely on recycled fiber are excluded.
