The amount of forestland in east Texas has been estimated at 11.8 million acres, with approximately 2.5 million acres classified as pine plantations. The majority of these plantations are owned by forest industry (71 percent), while non-industrial private forest landowners represent the next largest shareholder (23 percent). Pine plantations are typically managed to produce timber, so information is needed to make informed management decisions. Growth is one piece of information that managers often rely upon in their decision-making process. The purpose of this paper is to update the whole-stand growth and yield model for unmanaged loblolly and slash pine plantations in east Texas (Allen et al. 2010, Coble 2009) with additional remeasured plot data from the East Texas Pine Plantation Research Project. Additionally, the definition of dominant height was changed from the average height of the tallest 10 trees on the plot to the average height of the dominant and co-dominant trees on the plot.
