Informal Project Reports

Each published set of equations was developed from analyses of East Texas Pine Plantation Research Project (ETPPRP) data collected from the array of ETPPRP permanent research plots located throughout East Texas.

Project Report No. 56, Observed Growth Trends, Basal Area Per Acre In Square Feet, Loblolly And Slash Pine Plantations East Texas, J. David Lenhart, Jennifer Allen, Young-Jin Lee

Informal Project Reports

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.

Project Report No. 58, Observed Growth Trends, Average Total Height . . . Ten Tallest Trees, Loblolly And Slash Pine Plantations East Texas, J. David Lenhart, Jennifer Allen, Young-Jin Lee

Informal Project Reports

Observations from 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.

For each combination of site index and age class, an average observed total height of the ten tallest trees was calculated.

Based on these values, MAl (mean annual increment) and CAI (current annual increment) were calculated.

The values are depicted in graphs on the next six pages.

Project Report No. 54, Assessment Of Early Estimation Of Site Index, Loblolly Pine Plantations East Texas, J. David Lenhart, Jennifer Allen

Informal Project Reports

Observations from the Bast Texas Pine Plantation Research Project were available for analysis in this study.

In particular, observations are available that track the development of loblolly pine plantation parameters, such as age and height during 14, 15 and 16 year periods of time.

Fortunately. many of the tracks begin with initial measurements in plantations that were less than 5 years old.

These particular data were analyzed in this study. The results are depicted on the next 6 pages.
