The Percentage Of Trees Bearing Cones As A Predictor For Annual Longleaf Pine Cone Production, Thomas Patterson
The Percentage Of Trees Bearing Cones As A Predictor For Annual Longleaf Pine Cone Production, Thomas Patterson
Faculty Publications
The U.S. Forest Service has monitored longleaf pine cone production at sites throughout the southeastern United States for over 60 years. Data from the multi-decadal surveys have supported our understanding of the variability of stand-level cone production as it relates to environmental and ecological processes, and more broadly, how longleaf pine operates as a masting species. Cones from longleaf pine are counted each spring using visual surveys that follow a standard protocol. Rapid mast assessments have been proposed in the literature as an alternative to traditional methods, yet these approaches have not been examined for longleaf pine. In this study, …
Modeling Thinning In East Texas Loblolly And Slash Pine Plantations, Dean W. Coble
Modeling Thinning In East Texas Loblolly And Slash Pine Plantations, Dean W. Coble
Faculty Publications
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 …
