Loblolly pine site index curves constructed from age-height data

Abstract

Site index curves for natural stands and plantation stands of loblolly pine in the Southeast were constructed from temporary age height data by an anamorphic technique and two polymorphic techniques. These different systems of site index curves were evaluated using sectioned tree data. Evaluation results showed the anamorphic site index curves were best for the plantation stands, and the polymorphic curves constructed using a data stratification method were best for the natural stands.
