Research Report No. 28, Tree Content And Taper Functions For Planted Loblolly And Slash Pine Trees In East Texas, Update: June 1993, Revised: September 1993, Jaffirin Lapongan, A. Beth Vaughn, J. David Lenhart

Informal Project Reports

In 1987, tree content and tree taper functions for individual live standing planted loblolly and slash pine trees in East Texas were published 1. These equations were developed based on stem analyses of felled trees located adjacent to East Texas Pine Plantation Research Project (ETPPRP) permanent plots throughout East Texas. The 1987 report was based on 65 loblolly and 34 slash pine trees sampled during 1986. For both species, dbh (0) values ranged from about 2-12 inches and total height (H) values varied from about 10-60 feet.

Research Report No. 27, Site Index Equations For Loblolly And Slash Pine Plantations In East Texas, Update: 1993, A. Beth Vaughn, Jaffirin Lapongan, J. David Lenhart

Informal Project Reports

In 1986, equations to estimate site index in loblolly and slash pine plantations in East Texas were published. These equations were developed using data collected from East Texas Pine Plantation Research Project (ETPPRP) permanent plots distributed throughout East Texas. The site index prediction equations were designed to estimate tree height 25 years from planting, ie., index age = 25 years.

In the 1986 study, only data recorded during the first measurement cycle of the ETPPRP (1982- 1984) were available for analysis. Pairs of observed plantation age and a'verage !otal height of the ten tallest trees values were accessible from 150 …

Evaluating Susceptibility Of Red-Cockaded Woodpecker Cavity Trees To Southern Pine Beetle In Texas, William G. Ross, David Kulhavy, Richard N. Conner

Faculty Publications

Characteristics of loblolly (Pinus fuedu L.) and shortleaf (Pinus echinutu Mill.) pine trees favored by the endangered red-cockaded woodpecker, Picuides borealis (Vieillot) for nesting and roosting cavities over much of eastern Texas, tend to make these trees highly vulnerable to mortality from bark beetle attack. Resin flow and xylem moisture potential, often used as indicators of pine susceptibility to bark beetle mortality, were measured in several red-cockaded woodpecker cavity tree clusters in the Angelina and Davy Crockett National Forests. No differences in xylem moisture potential were found, while resin flow varied by site, tree species, and cavity tree type. With …

Soil Properties Relating To Height Growth Of Loblolly Pine On Four Major Soil Series In East Texas, R. Larry Willett, M. Victor Bilan

Faculty Publications

Stem analysis was used to obtain age and height data for loblolly pine (Pinus taeda L.) stands growing on Bowie, Fuquay, Sacul, and TroupxlsTnortheastern Texas. The soil profiles were described and bulk soil samples were taken in each sample stand. Selected physical and chemical soil properties were measured for each soil horizon. Stepwise regression analysis was used to correlate average stand height at ages 5, 10, 20, and 30 years with soil properties. Strong associations were found between stand height and properties which relate to available soil moisture holding capacity, soil permeability, and soil aeration. For Bowie, Fww , and …

Research Report No. 23, Environmental Factors Influencing Diameter Development Within East Texas Loblolly Pine Plantations, Pilis Malim

Informal Project Reports

An assessment of the role of various environmental fa::tors on the development of four measures of diameter--minimum, arithmetic mean, quadratic mean and maximum- -was conducted for lob lolly pine ( Pinus taeda L.) plantations in East Texas. Of 12 environmental f~tors analyzed, only slope percent, two measures of non- planted vegetation Md surface soil pH significantly influenced diameter development.

Site/Stand Factors Influencing Nantucket Pine Tip Moth In Loblolly Pine Plantations, David Kulhavy, W. G. Ross, James R. Meeker, W. David Tracey

Faculty Publications

Tip moth infestation and loblolly pine growth were examined on sandy, loamy and clayey sites in 2-3 year old plantations. Infestations were greatest on loamy sites. Following fertilizer and herbicide applications, tip moth infestations were lowest on fertilized plots following application of phosphorus.

Research Report No. 16, Stand Structure And Yield Of Loblolly Pine Plantations In East Texas, Update: 1987, J. David Lenhart

Informal Project Reports

An updated diameter distribution yield prediction system is presented for loblolly pine ( Pinus taeda L. ) plantations on non- old-fields in East Texas. The new revised system was developed using data from initial measurement ( 1982-84) and f irst remeasurement ( 1985-87) of the East Texas Pine Plan tat ion Research Project permanent plots.

Management And Pest Management Considerations On Droughty Soils: Four Year Results, David Kulhavy, Kenneth G. Watterson, James Kroll, James R. Meeker

Faculty Publications

Four year survival of pines on droughty (Typic Quartzips~mments) soils was best for longleaf pine and Terr-Sorb -treated loblolly pine. Pest considerations include town ants and Nantucket pine tip moths on loblolly pine. Untreated loblolly pine had reduced leader and total height growth anH increased tip moth infestations, compared to Terra-Sorb and clay-slurry treated loblolly pine. Soil texture averaged less than eight percent silt and clay combined in the treatment areas.

Three species of pines (loblolly, slash and longleaf) were planted with four treatments (loblolly and slash = bareroot, clay dip slurry and TerrasorH ; longleaf = containerized) to test survival on droughty, typic quartzipsamments soils. At the end of the first season, survival~s significantly better for the containerized longleaf and Terrasoro treated loblolly pine (81 and 85%) followed by untreaRed loblolly pine (51%), clay-treated loblolly (50%), then Terrasorb treated slash (48%), untreated slash (41%) and clay-treated slash (36%).

Factors Determining Natural Reproduction Of Longleaf Pine On Cut-Over Lands In Lasalle Parish, Louisiana, Herman H. Chapman

Yale School of the Environment Bulletin Series

The original ' pine forests, of the southern states covered from 125 to 130 million acres of land, about two-thirds of which was Longleaf pine. Four-fifths of this area had been cut over by 1920, leaving about 230 million acres, one-half of which is Longleaf pine. Of the cut-over lands, 31 million acres have not restocked. The Longleaf pine has thus been the principal tree crop on about 85 million acres of land, of which 11% million acres remained' in 1920, giving a cut-over area of nearly 73 million acres, or 114,062 square miles. This area is nearly half the …
