The spatial changes in Timber Mart-South reporting may be viewed as a greater challenge than its temporal inconsistencies. From 1976-1991 most states had three reporting regions. In the Atlantic coast states, these three regions generally corresponded to the coastal plain (region 3), Piedmont (region 2), and mountains (region 1). Along the Gulf of Mexico different schemes for division were used. Regardless, in 1992 Timber Mart-South reconfigured each state into two regions, a spatial configuration that continues to today. The exceptions to this three-to-two change were Texas, which began with two regions and thus underwent no change, and Florida, which began with three regions but which lost its southern-most region. Kentucky was a third exception but was not included in this study.
