Informal Project Reports

Site index prediction equations for loblolly ( Pinus taeda L.) and slash ( Pinus elliottii Engelm. ) pine plantations in East Texas.

Project Report No. 46, Loblolly Pine Plantations In East Texas Two Harvest Schedules No Thinning & Final Harvest At 25 Years Thin At 10 Years & Final Harvest At 25 Years Sawlog/Veneer Wood Flow Comparison, A Simulation, J. David Lenhart, Jennifer Allen

Informal Project Reports

DOES A THINNING AT 10 YEARS WITH FINAL HARVEST AT 25 YEARS INCREASE SAWLOG/VENEER 1000 FLOW? DOES A THINNING AT 10 YEARS WITH FINAL HARVEST AT 25 YEARS INCREASE NET PRESENT VALUE?

Project Report No. 49, Loblolly Pine Plantations In East Texas Two Harvest Schedules No Thinning, Final Harvest At 30 Years Thin At 20 Years, Final Harvest At 30 Years Sawlog/Veneer Wood Flow Comparison, A Simulation, J. David Lenhart, Jennifer Allen

Informal Project Reports

A two-page spreadsheet was designed to represent the simulation model. In the spreadsheet, the user can easily conduct simulation runs. Runs that ascertain the effect of different combinations of biological and economical factors. Sensitivity of wood flow and net present value to plantation management attributes. A forester can use the spreadsheet to investigate specific combinations of factors. This spreadsheet is a versatile analytical tool for comparing management scenarios.

Project Report No. 45, Loblolly Pine Plantations In East Texas Thinned And Unthinned - Total Wood Flow Comparison A Simulation, J. David Lenhart, Curtis Vanderschaaf

Informal Project Reports

In East Texas loblolly pine plantations, is the total wood flow from a thinning and a final harvest greater than total wood flow from just a final harvest? That is, does including one thinning in the rotation have an advantage over no thinning in the production of wood during the rotation?

Project Report No. 42, High/Low Counties, Curtis Vanderschaaf, J. David Lenhart

Informal Project Reports

Which East Texas counties tend to have the highest and lowest values of certain pine plantation attributes?

Loblolly and Slash pine plantation attributes considered are:
• Ability of area to grow pine plantations •
• Percent of pines with crooked stems •
• Pecent of pines with stem fusiform rust •
• Visual quality •

Project Report No. 43, Site Index Equations For Loblolly And Slash Pine Plantations In East Texas, Update: 1996, Don Campbell, Steve Croft, Mark Dougharty, Doug Foster, John Hawkins, William Howard, Young Jin Lee, Jason Love, Derek Mckean, Kendall Watts, Kurtis White

Informal Project Reports

In this update, after combining the data from the two subplots comprising each ETPPRP plot, the number of age-height pairs available for this analysis is 1,520 loblolly and 658 slash. the It is anticipated that the equations in this :996 update may productivity of East Texas loblolly and slash pine plantations quantify in a more accurate and reliable manner than the four previous sets 0: equations.

Project Report No. 41, Perils Facing Etpprp Plots, 1982-1995, J. David Lenhart

Informal Project Reports

A total at 256 permanent growth and yield research plots were installed by the college of Forestry at Stephen P. Austin State University in pine plantations throughout Bast Texas during 1982-84. of the total number, 178 were installed in loblolly (Pinus t.ede L.), and 78 were placed in slash (P!nu. elliotti! Bngelm.) pine plantationa. The purpose of the plots is to provide data for the East Texas Pine Plantation Research Project (ETPPRP).

Project Report No. 40, Influence Of Plantation Variables On Crown Height, Young-Jin Lee, J. David Lenhart

Informal Project Reports

A plantation management question ... Is it possible to estimate the distance from the ground to the first live branch of a planted pine tree? The Bast Texas Pine Plantation Research Project (ETPPRP) in a recent investigation addressed this question, and the answer was yes. An analysis of the ETPPRP data set produced equations to estimate crown height (the distance from the ground to the first live branch).
