Long-Term Overstory Vegetation Responses To Prescribed Fire Management For Longleaf Pine At Big Thicket National Preserve, Deanna M. Boensch

Electronic Theses and Dissertations

At the western edge of the longleaf pine (Pinus palustris) range, federal land managers have burned the forests of Big Thicket National Preserve to bring back the structure and diversity of the longleaf pine forest. In the early 1990’s, a four year study was conducted by Rice University, and the National Park Service continued monitoring the study’s fire ecology research plots. After two decades of data collection, ordination was applied to species abundance data to examine changes in vegetation communities from a variety of prescribed fire treatments and controls. The vegetation data was separated by size class to include overstory, …

An Investigation Of Hydrogeologic, Stratigraphic, And Structural Controls On Acer Grandidentatum Communities In A Karst Landscape, Owl Mountain Province, Fort Hood Military Installation, Texas, Melinda S. Faulkner

Electronic Theses and Dissertations

The Owl Mountain Province is located within the Fort Hood Military Installation, an approximately 880 km2 installation established in the 1940s in Bell and Coryell counties, Texas, which has undergone extensive land use changes associated with military training, maintaining much of the vegetation in early succession. This study investigates thelithologic, stratigraphic, and structural controls on the hydrologic, hydrogeologic, and geomorphologic evolution of the Owl Mountain Province as expressed by mesic vegetation communities, including Pleistocene relicts Acer grandidentatum, within karst terrains. These systems exhibit complexly overprinted speleogenetic evolutions within a dynamic groundwater regime resulting from regional climate shifts throughout the …

Bullish On Forestry Careers, Steven H. Bullard, Thomas J. Straka

Faculty Publications

During the next decade, baby boomer-aged foresters, those born from 1946 to 1964, will be retiring in large numbers. This retirement trend is true for all sectors of forestry employment, from state and federal agencies to private firms and industries.

Forestry employers in both public and private sectors are clamoring for more graduates, as well as for more diverse graduates, from forestry degree programs. With looming retirements and industry growth, employers can project the number of positions opening, and they are aware that U.S. forestry schools are not producing sufficient graduates to fill the positions.

Project Report No. 69, Observed Growth And Yield Of Loblolly And Slash Pine Plantations In East Texas, Dean W. Coble, Katherine Pendergast

Informal Project Reports

Forestland in East Texas is an estimated 12.1 million acres, with approximately 2.9 million acres (24%) classified as pine plantations on private land. Because pine plantations are typically managed for timber production, information regarding tree growth is needed to make informed management decisions. An understanding of how growth factors such as tree volume, diameter, height and basal area are affected by site index, trees per acre and age in East Texas enables plantation managers to make the management decisions necessary to maximize timber production.

Stream Water Quality And Quantity Effects From Select Timber Harvesting Of A Streamside Management Zone, Luke Sanders, Matthew W. Mcbroom

Faculty Publications

A naturally regenerated, even aged, mixed pine/hardwood, streamside management zone (SMZ) was selectively harvested in May 2006. The 27.8 ha SMZ buffered an intermittent headwater stream draining a 98 ha watershed. The harvest complied with Texas, USA best management practices (BMPs) by maintaining a minimum SMZ width of 15 m on either side of the channel, retaining a minimum basal area (BA) greater than 11.47 m² ha^-1, and minimizing forest floor and stream channel disturbance. No changes in soil bulk density were measured with only a slight increase in bare soil. No changes in water quality or …

Sub-Pixel Classification Of Forest Cover Types In East Texas, Joey Westbrook, I-Kuai Hung, Daniel Unger, Yanli Zhang

Faculty Publications

Sub-pixel classification is the extraction of information about the proportion of individual materials of interest within a pixel. Landcover classification at the sub-pixel scale provides more discrimination than traditional per-pixel multispectral classifiers for pixels where the material of interest is mixed with other materials. It allows for the un-mixing of pixels to show the proportion of each material of interest. The materials of interest for this study are pine, hardwood, mixed forest and non-forest. The goal of this project was to perform a sub-pixel classification, which allows a pixel to have multiple labels, and compare the result to a traditional …

The Mapping Of Composite Pollen From Point Sampled Data And Cartographic Generalization, Peter P. Siska, I-Kuai Hung, Vaughn M. Bryant Jr.

Faculty Publications

Pollen grains are microgametophytes produced by angiosperm and gymnosperm plants. They are responsible for transporting genetic material and carrying out fertilization. The study of pollen has numerous practical applications such as plant biodiversity, paleoclimatology, archaeology, allergy studies, the study of nectar sources in honey (melissopalynology), searching for sources of petroleum, and more recently, using pollen as a trace evidence component in forensics. Once pollen grains become airborne, their dispersal is controlled by a number of physical factors that determine the deposition distance from their source area. The purpose of this work is to study spatial pattern of composite pollen in …

Faculty Publications

In order to maintain a proper balance between development pressure and water resources protection, and also to improve public participation, efficient tools and techniques for soil and water conservation projects are needed. This paper describes the development and application of a web-based watershed management spatial decision support system, WebWMPI. The WebWMPI uses the Watershed Management Priority Indices (WMPI) approach which is a prioritizing method for watershed management planning and it integrates land use/cover, hydrological data, soils, slope, roads, and other spatial data. The land is divided into three categories: Conservation Priority Index (CPI) land, Restoration Priority Index (RPI) land, and …

Project Report No. 67, A Whole-Stand Growth And Yield Model For Unmanaged Loblolly And Slash Pine Plantations In East Texas, Dean W. Coble, Micky G. Allen Ii, Jimmie L. Yeiser, I-Kuai Hung

Informal Project Reports

The amount of forestland in east Texas has been estimated at 11.8 million acres, with approximately 2.5 million acres classified as pine plantations. The majority of these plantations are owned by forest industry (71 percent), while non-industrial private forest landowners represent the next largest shareholder (23 percent). Pine plantations are typically managed to produce timber, so information is needed to make informed management decisions. Growth is one piece of information that managers often rely upon in their decision-making process.

Diameter Distribution Models: Loblolly Pine Plantations, Dean W. Coble

Data

A parameter recovery procedure for the Weibull distribution function based on four percentile equations was used to develop a new diameter distribution yield prediction model for unmanaged slash pine (Pinus elliottii Engelm.) plantations in east Texas. This new model was similar in structure to the model of Lee and Coble (2006) in their work with east Texas loblolly pine plantations. The new model was compared to the diameter distribution model of Lenhart (1988), which was developed for slash pine plantations in east Texas, as well as to two other models developed using iterative techniques suggested and inspired by Cao (2004). …

Site Index Equations, Dean W. Coble

Whole-Stand Models: Loblolly And Slash Pine Plantations, Dean W. Coble

Data

A new compatible whole-stand growth and yield model to predict total tree cubic-foot volume per acre yield (outside and inside-bark) was developed for unmanaged loblolly pine (Pinus taeda) and slash pine (Pinus elliottii) plantations in east Texas. This model was compared to the non- compatible whole-stand model of Lenhart (1996) and the Lenhart (1996) model refit to current data. For the two species, all three models were evaluated with independent observed data. The model developed in this study out-performed both Lenhart models in prediction of future yield and basal area per acre for all age classes combined and by five-year …
