We describe here selected technical aspects of a large-scale sustainability analysis of wood supply in Georgia with particular focus on: i) available data; ii) species group definition; iii) yield tables. The study is conducted at the School of Forest Resources, University of Georgia, as a new cooperative effort financed by the Traditional Industry Program 3 and the D.W. Warnell School of Forest Resources, University of Georgia. We identify here the directions, resources and problems in such a large scale of modeling. At the current state the analysis is based on basic inventory summaries founded on the databases provided by the USDA Forest Service Forest Inventory Analysis unit. We explain our main assumptions based on available literature, and unpublished research on intensive plantation management.
