Simulated Mine Land Reclamation Impact On Biomass Partitioning And Nutrient Contents In Loblolly Pine, Osarumen Egharevba

Electronic Theses and Dissertations

Forest productivity on reclaimed mine land is hindered by soil compaction. Different techniques have been used to alleviate the effect of compaction to various degrees of success. The Forestry Reclamation Approach (FRA) was developed in the Appalachians and has been used to improve forest productivity on reclaimed mines in this region. The FRA provides a step by step method designed to reduce compaction, control erosion, provide land stabilization and accelerate forest succession. This method had not been evaluated in the Gulf Coastal Plain, where the pan scraper reclamation method is commonly used. However, using pan scrapers increases mine soil compaction …

Modeling Early Responses Of Loblolly Pine Growth To Thinning In The Western Gulf Coastal Plain Region, Yuhi Weng, J. Grogan, Dean W. Coble

Faculty Publications

Growth response to thinning has long been a research topic of interest in forest science. This study presents the first 3–4 years of response of loblolly pine (Pinus taeda L.) growth to thinning at different intensities. Data were collected from the East Texas Pine Research Project’s region-wide loblolly pine thinning study, which covers a wide variety of stand conditions. Four treatments, light, moderate, and heavy thinning, respectively having 370, 555, and 740 residual trees per hectare after thinning, and an unthinned control, were included. Individual tree diameter at breast height (dbh) and total height were recorded annually for the …

Split-Season Herbaceous Weed Control For Full-Season Seedling Performance, Jimmie L. Yeiser, Andrew W. Ezell

Faculty Publications

Results from four loblolly pine (Pinus taeda L.) sites, one in each of MS and TX in 2001 and again in 2002, are presented. Twelve herbicide treatments and an untreated check were tested. Herbicide treatments were applied early (mid- March), late (mid-May), both timings, or not at all to achieve, early- late-, full-season, or no weed control. When averaged across all four sites and compared to the early treatment, bare ground was less from April through July and April through November on late treated and untreated plots, respectively. Full-season weed control provided numerically more bare ground than other treatments. When …

Growth Response From Herbicide, Prescribed Fire And Fertilizer Treatments In Midrotational Loblolly Pine: First-Year Results, Mary Michelle Barnett, Sandra Rideout, Brian P. Oswald, Kenneth W. Farrish, Hans Michael Williams

Faculty Publications

This study was initiated to determine growth response resulting from the application of prescribed fire and herbicide, with and without fertilizatio.n. In. southeast Texas, herbicide, prescribed fire and fertilizer treatments were applied in m1d:rotat1onal loblolly pine plantations 1.5 years after thinning. Five replications were established at. each of two study sites located on similar soils, aspects and slopes. Half of each replication. was randomly selected and fertilized. Eight treatment plots were established 1n e~ch replication with one of each of the four treatments of control, herbicide, fire, and herb1c1de/flre randomly applied to fertilized plots and one of each of the …

Four-Year Growth Results From 16 Year Old Intensively Managed Low Density Loblolly Pine Plantations, A. Gordon Holley, Leslie A. Dale, Gary D. Kronrad

Faculty Publications

In 1994 eighty four permanent research plots were established in two twelve year-old loblolly pine (Pinus taeda) plantations in East Texas. Plots differed in relation to: soil-site type, density of trees per acre, fertilization treatments, and competing vegetation control. Three levels of thinning treatments reduced the basal areas to 36,60, and 84 square feet of basal area (approximately 100,200, and 300 stems, respectively) per acre. All residual trees were pruned to a height of 25 feet. Plots were re-measured in 1995, 1996, and 1998. Significant differences in diameter and height growth rates were detected in 1996 and 1998. Average diameter …

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).

Project Report No. 38, Average Observed Fusiform Rust Transition Paths, O. Schabenberger, T. G. Greroire, J. David Lenhart

Informal Project Reports

fusiform rust ( Cronatrium quercuum [Berk. ] Miyabe ex Shirai f . sp . tusiforme L. ) is a devastating disease in loblolly ( Pinus taeda L. ) and slash ( Pinus elliottii Englem. ) pine plantations throughout the southern United States . Pine stems infected with fusiform rust are subject to hazards such as wind breakage, and if a pine stem with a gall on it does survive to harvest, utilization of the infected stem piece may be down-graded from possible lumber to probable pulpwood or maybe completely discarded .

Research Report No. 32, Trends Of Non-Straight Tree Stems In Loblolly And Slash Pine Plantations In East Texas, 1985-1994, H. Alexis Ross, J. David Lenhart

Informal Project Reports

Trees from East Texas loblolly ( Pinus taeda L. ) and slash ( Pinus effiottii Engelm. ) pine plantations are one of the sources of raw material for conversion into products such as paper, veneer and lumber by East Texas forest product mills. The utilization of the planted trees may depend on various biological and economical factors. Factors such as tree size, tree condition, stumpage prices and interest rates can play a role in the merchandizing process.

One of the factors, tree condition, may be affected by tree crown position in canopy, incidence of disease, single stem and straightness of …

Informal Project Reports

Of the approximately 11.2 million acres of forest in East Texas, about 2.5 million acres have been planted with loblolly pine trees ( Pinus taeda L. ) and 500,000 acres with slash pine trees ( Pinus elliottii Engelm. ). These plantations are owned by public, industrial and non-industrial private entities with industrial ownership dominating. Even though most pine plantations in East Texas are relatively young (20 years or less), plantation information is needed for management decision-making.

Research Report No. 30, A Guide For Timing Initial Tree Harvests In East Texas Loblolly And Slash Pine Plantations, J. David Lenhart, H. Alexis Ross

Informal Project Reports

In East Texas, there are approximately 3 million acres of loblolly ( Pinus taeda L. ) and slash ( Pinus elliottii Engelm. ) pine plantations. Most of these plantations, which represent about 25% of the forested area of East Texas, have been planted since 1970.

As these planted trees age, East Texas foresters may be considering initial timber harvesting decisions for unthinned plantations. Often the timing of the harvests can be determined by considering combinations of economic and non-economic values, utilization standards and timber growth' factors. However, in some situations, it may be appropriate to ascertain the proper timing by …

Informal Project Reports

In 1986, equations to estimate site index in loblolly and slash pine plantations in East Texas were published (Lenhart et al. 1986). Subsequently, updated site index prediction equations were published in 1993 (Vaughn et al. 1993). Both sets of 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.

Data for the 1986 and 1993 site index prediction equations were from measurements of the ETPPRP permanent plots during 19182-1984 …

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.
