Project Report No. 60, Observed Per-Acre Volume Growth Trends, 28 Individual Observations, Unthinned Loblolly Pine Plantations East Texas

Individual plot data from the East Texas Pine Plantation Research Project were available for analysis in this study. Each plot consists of two subplots. Each subplot is considered an observation. The analysis was limited to individual observations ages 24 years and older. All observations are unthinned. For each observation, cubic feet total stem wood and bark per acre was calculated. Based on these values, MAI (mean annual increment) was calculated. The values (plus observed trees per acre) are depicted in graphs on the next 28 pages
