Effects Of Fertilization And Herbicides On Growth Of Young Loblolly Pine And Infestations Of Nantucket Pine Tip Moth (Lepidoptera: Tortricidae), David L. Kulhavy
Faculty Publications
A 2-year-old pine plantation was selected to receive treatments of fertilizers and herbicides to evaluate effects on Nantucket pine tip moth infestations and the tree growthparameters of height, diameter and volume increment. Nitrogen and phosphorus fertilizers, and hexazinone and sulfometuron methyl herbicides were used in creating six treatments: (i) control; (ii) phosphorus; (iii) nitrogen and phosphorus; (iv) phosphorus and herbicide; (v) nitrogen, phosphorus and herbicide; and (vi) herbicide. Treatments were applied in 1987 and 1988. In 1987, trees treated with nitrogen, phosphorus and herbicide had significantly greater height, diameter and volume growth than trees not receiving fertilizer treatments, but did …

Economic Analysis Of Pruning And Low-Density Management Compared To Traditional Management Of Loblolly Pine Plantations In East Texas, Ching Hsun Huang, Gary D. Kronrad
Faculty Publications
Economic analyses were conducted to compare traditional loblolly pine (Pinus taeda L.) timber management to low-density management combined with pruning in East Texas. Soil expectation values were used to determine the financially optimal thinning and final harvesting schedules (including rotation length, and the timing, frequency and intensity of thinning). Two stumpage price assumptions were made: market price and premium price for pruned, clear sawlogs. Five site indices (50 to 90) and six real alternative rates of return (ARR) (2.5 to 15.0%) were employed. Results indicate that if the market price of sawtimber is $450/mbf, traditional management is more profitable for …
How Are Investment Returns Affected By Competition Control And Southern Oak Seedling Survival?, D. L. Grebner, A. W. Ezall, D. A. Gaddis, Steven H. Bullard
How Are Investment Returns Affected By Competition Control And Southern Oak Seedling Survival?, D. L. Grebner, A. W. Ezall, D. A. Gaddis, Steven H. Bullard
Faculty Publications
Increasing numbers of landowners are establishing hardwood plantations to satisfy their management objectives. Despite a dearth of research on competition control and its effects on initial hardwood plantation survival and investment returns, this study examines alternative competition control regimes for southern oak establishment. The analysis includes estimates of land expectation value for comparing alternatives. Our results suggest that greater returns can be achieved for southern oaks during both good and bad rainfall years, using methods that maximize survival through competition control.

Comparison Between Regenerators And Non-Regenerators In Mississippi: A Discriminant Analysis, Kathryn G. Arano, Ian A. Munn, John E. Gunter, Steven H. Bullard, Max L. Doolittle
Faculty Publications
Nonindustrial private forestland (NIPF) landowners in Mississippi who recently harvested timber were surveyed to examine their regeneration behavior. Differences between regenerators and nonregenerators were investigated by looking at the different factors affecting reforestation decisions. A discriminant analysis was used to identify factors that were useful in differentiating between regenerators and nonregenerators. Ownership size; sociodemographic characteristics such as income, education, place of residence, and age; awareness of existing government incentive/assistance programs; and participation in educational programs were significant variables in differentiating between regenerators and nonregenerators. Landowners who own larger timberlands had a higher propensity to engage in regeneration activities after harvests. …
Factors Affecting Mississippi’S Nipf Landowners’ Reforestation Decisions, Kathryn G. Arano, John E. Gunter, Steven H. Bullard, Larry Doolittle, Ian A. Munn
Factors Affecting Mississippi’S Nipf Landowners’ Reforestation Decisions, Kathryn G. Arano, John E. Gunter, Steven H. Bullard, Larry Doolittle, Ian A. Munn
Faculty Publications
Non-industrial private forest (NIPF) landowners have played an increasingly important role in the nation's timber economy. Nearly 70% of the forestland in the South is owned by NIPF landowners (Powell et al., 1994). In Mississippi alone, these landowners control approximately 66% of the state's forestland base (Hartsell and London, 1995). Therefore, NIPF landowners are expected to provide a large portion of the state's supply of timber. However, whether they do so depends largely on how their timberlands are managed. Forest management decisions of NIPF landowners can impact future timber supply due to the magnitude of their collective ownership.

Perceived Benefits Of Mississippi’S Forestry Best Management Practices, Amanda L. Husak, Stephen C. Grado, Steven H. Bullard, Chuck Jepsen
Faculty Publications
The primary goal of many nonindustrial private forest (NIPF) landowners, forestry consultants, and timber industry professionals is to increase revenues from their forestland. Most often, increased revenues are a result of harvesting timber stands from the site. However, the chances of increased revenues can be greatly reduced if the stands are improperly managed or voluntary Best Management Practices (BMPs) guidelines are not followed.

Reforestation Of Harvested Timberlands In Mississippi: Behavior And Attitudes Of Non-Industrial, Private Forest Landowners, J. E. Gunter, Steven H. Bullard, M. L. Doolittle, K. G. Arano
Faculty Publications
Southern forests play an increasingly important role in the timber economy as per capita demand for wood continues to expand. Moreover, harvest restrictions in the Pacific Northwest in the early 1990s shifted a large portion of United States demand for softwoods to the South. In Mississippi, most of the forestland is owned by non-industrial private forest (NIPF) landowners. Approximately 314,000 NIPF landowners control 66 percent of the state’s forestland base (Hartsell and London 1995). The sizable acreage of timberland held by NIPF landowners nationally and in-state underscores the importance of their role in the timber economy and weighs heavily in …

Adjusting Discount Rates For Income Taxes And Inflation: A Three-Step Proces, Steven H. Bullard, John E. Gunter
Faculty Publications
Income taxes and inflation must be correctly accounted for in forest valuation and investment analysis. In a specific analysis, the discount rate and all costs and revenues should be either before or after taxes, and they should include or exclude inflation consistently. We summarize eight formulas for adjusting discount rates for income taxes and inflation in a simple three-step process. A one-page figure is presented that can be used as a stand-alone tool for correctly adjusting discount rates. South. J. Appl. For. 24(4):193-195.
