Abstract
Growth and yield data from across 13 southern States, collected from 1967 to 2004 from fully-stocked even-aged southern hardwood forests on a variety of site types, was used to calculate site index curves. These derived curves provide an efficient means to evaluate the productivity-age relation which varies across many sites. These curves were derived for mixed-species and represent a substantial improvement over previously available curves of this nature. These site index curves will be used as a "productivity driver" in the development of growth and yield models for these forest types.
