Observations fr9m the East Texas Pine Plantation Research Project were available for analysis in this study. We limdted the observations to site index classes 60. 70 and 80 feet. And age classes were set at three-year intervals.
Por each combination of site index and age class. an average observed basal area in square feet per acre was calculated.
Based on these values, HAl (mean annual increment) and CAl (current annual increment) were calculated.
The values are depicted in graphs on the next six pages.
