Modeling thinning in east Texas loblolly and slash pine plantationsThis article is part of a larger document. View the larger document here.
A new thinning model was proposed for loblolly pine (Pinus taeda L.) and slash pine (P. elliottii Engelm.) plantations in east Texas. The new model follows the index of suppression methodology introduced by Pienaar (1979). It was implemented in a new whole stand growth model for loblolly and slash pine plantations in east Texas (Coble 2009). The new thinning model performed similarly to existing Pienaar-type models for east Texas and the Southeastern United States across a range of site quality. The predicted basal area development consistently approached the unthinned counterpart, which is consistent with results from other studies. The new thinning model should be fully tested when empirical data become available. In the meantime, it can be used to model thinned loblolly and slash pine plantations in east Texas ranging in age from 5 to 40 years.
