The Schnute growth function was used in this study to model site index for unmanaged or low-intensity managed loblolly pine (Pinus taeda, L.) and slash pine (Pinus elliottii, Engelm.) plantations in east Texas. The algebraic difference approach was used to derive an anamorphic base-age invariant site function that was fi t as a fi xed base-age anamorphic site function (base age = 25 years). The dataset was comprised of 1,135 and 502 serially correlated height-age observations of loblolly and slash pine, respectively, which were collected over a 20-year-period as a part of the East Texas Pine Plantation Research Project (ETPPRP). …
