Fifth-Year Pine Growth Response To Woody Release Treatments In Young Loblolly Plantations, Andrew W. Ezell, Jimmie L. Yeiser, L. R. Nelson
Fifth-Year Pine Growth Response To Woody Release Treatments In Young Loblolly Plantations, Andrew W. Ezell, Jimmie L. Yeiser, L. R. Nelson

Across the South, many forest land managers may opt to use mechanical site preparation, especially when soil treatments are deemed appropriate. While these mechanical treatments may be highly effective at addressing a particular soil problem or debris issue, they are typically less effective at control of competing vegetation. In these scenarios where pines are planted, a woody release treatment using herbicides is usually applied at the end of either the first or second growing season. The purpose of these applications is to provide long-term control of the woody competitors with typically short-term control of any herbaceous species on the site.
Effects Of Treatments Using Mat-28 For Pine Site Preparation, Andrew W. Ezell, Jimmie L. Yeiser, Pat Minogue
Effects Of Treatments Using Mat-28 For Pine Site Preparation, Andrew W. Ezell, Jimmie L. Yeiser, Pat Minogue
Faculty Publications
Site preparation for pine plantation establishment continues to be the principal use of herbicides in the South. Due to the timing of the work and the cost involved, these applications are critical in both biological and economic terms. In an effort to improve performance in both considerations, a study was undertaken to evaluate a number of herbicide compounds in site preparation applications. A total of 12 treatments were applied with three replications on three sites in a randomized complete block design. Applications were completed in mid-July using a total spray volume of 15 gpa. Treatments included MAT-28 applied alone at …
Project Report No. 66, Metric Volume And Biomass Prediction Equations For Loblolly And Slash Pine Trees Planted In Unmanaged Pine Plantations In East Texas, Dean W. Coble, Young-Jin Lee, J. David Lenhart
Project Report No. 66, Metric Volume And Biomass Prediction Equations For Loblolly And Slash Pine Trees Planted In Unmanaged Pine Plantations In East Texas, Dean W. Coble, Young-Jin Lee, J. David Lenhart
Informal Project Reports
Metric equations are presented to predict the volume of wood and/or biomass contained in individual loblolly (Pinus taeda, L.) and slash (Pinus elliottii, Englem.) pine trees growing in unmanaged pine plantations in east Texas. Taper equations are also presented for both species that describe tree form in metric units.
Nantucket Pine Tip Moth Control And Loblolly Pine Growth In Intensive Pine Culture: Two-Year Results, David Kulhavy, Jimmie L. Yeiser, L. Allen Smith
Nantucket Pine Tip Moth Control And Loblolly Pine Growth In Intensive Pine Culture: Two-Year Results, David Kulhavy, Jimmie L. Yeiser, L. Allen Smith
Faculty Publications
The Nantucket pine tip moth, Rhyacionia frustrana (Comstock) (NPTM), is an important pine regeneration insect in the Eastern and Southern United States (Berisford 1987). Larval feeding in meristematic tissue of young pines causes significant damage, particularly in areas where forest regeneration favors its proliferation (Yates and others 1981). Southeastern industrial forestry currently emphasizes establishment of large, homogeneous pine plantations to maximize production of wood and fiber. This forest management practice also creates optimal conditions for phytophagous insects, whose sole or primary hosts are pine trees. Increased damage by NPTM following vegetation control treatments may include improved suitability of pine tissue …
Management Of Droughty Site: Typic Quartzipsamments, Ecological Considerations, David Kulhavy, W. G. Ross, L. Allen Smith, R. R. Cahal
Management Of Droughty Site: Typic Quartzipsamments, Ecological Considerations, David Kulhavy, W. G. Ross, L. Allen Smith, R. R. Cahal
Faculty Publications
Pine plantations on Typic Quartzipsamments in East Texas are difficult to establish. Forest management options following clearcutting are limited. A 12 year regeneration study of the growth and survival of loblolly, Pinus faeda, L. shortleaf, P. echinata Mill., slash, f. elliofii Engelm and longleaf pines P. pa/u&is Mill. was conducted to determine optimum tree species and treatments for reforestation. With successful regeneration also comes insects and pathogens. Impacts of the Nantucket pine tip moth, Rhyacionia frusfrana, (Comstock) and the Texas leaf-cutting ant, Affa texana, (Buckley) will be discussed in the context of droughty site management.
Project Report No. 41, Perils Facing Etpprp Plots, 1982-1995, J. David Lenhart
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).

Research Report No. 24, Hyperstand 1.0: A Hypercard Computer Program For Estimating Yield Of East Texas Pine Plantations, Eric L. Taylor, A. Gordon Holley
Informal Project Reports
A computer program for estimating per ~e yield for lob lolly and slash pine plantations in East Texas is presented. The program, HYPERSTAND 1.0, is written in HYPERCA.RD and 1s designed to run on MACINTOSH computers. In order to run, HYPERSTAND requires the application program HYPERCA.RD l .2.
