The Effect Of Carbon Revenues On The Rotation And Profitability Of Loblolly Pine Plantations In East Texas, Ching Hsun Huang, Gary D. Kronrad
The Effect Of Carbon Revenues On The Rotation And Profitability Of Loblolly Pine Plantations In East Texas, Ching Hsun Huang, Gary D. Kronrad
Faculty Publications
This study determined the profitability and financially optimal thinning and final harvest rotation of loblolly pine (Pinus taeda) managed exclusively for timber production or for dual products of timber production and carbon sequestration. The results suggest that 1) depending on landowner’s alternative rate of return, the inclusion of carbon revenues in forest management may shorten or prolong the optimal timber-carbon rotation length, compared to the optimal rotation that maximizes timber value only; 2) the effect of carbon revenues on the optimal rotation length and the percentage gain in soil expectation value is larger on low-productivity sites than on high-productivity sites, …

Loblolly Pine Growth Response To Mid-Rotational Treatments In An Eastern Texas Plantation, Mohammad M. Bataineh, Amanda L. Bataineh, Brian P. Oswald, Kenneth W. Farrish, Hans Michael Williams
Faculty Publications
The effects of mid-rotational treatments (herbicide, prescribed burn, combination of herbicide and burn, and fertilization) on growth of loblolly pine were evaluated. Five replicates were established in a split-plot experimental design with fertilizer treatments as the whole-plot factor and competition control treatments as the sub-plot factor. Growth response was measured (as change in diameter, total height, and volume) at 8 months and again 4 years after treatments were applied. Mid-rotational treatments failed to enhance diameter, height, and volume growth of loblolly pine. However, a small positive response of diameter growth to fertilization was detected. Height growth was not significantly affected …
The Effects Of Sower And Bed Density On Bareroot Loblolly Pine Seedling Morphology And Early Height Growth, Hans M. Williams, Tim Stewart
The Effects Of Sower And Bed Density On Bareroot Loblolly Pine Seedling Morphology And Early Height Growth, Hans M. Williams, Tim Stewart
Faculty Publications
Precision sowing is commonly used at forest tree nurseries in order to improve the growing space uniformity of seedlings in the beds. Temple-Inland Forest Products Corporation recently purchased a vacuum sower and requested a study be conducted comparing their new sower with a drill sower on the morphological characteristics of loblolly pine (Pinus taeda L.) at lifting. The study was conducted in 2000 and repeated in 2001. The seed were sown using the two sower types to achieve four densities of 161, 215, 269, and 323 seedlings/m2. Two half-sibling families were tested in 2000, and one halfsibling family was …
Winter Food Habits And Preferences Of Northern Bobwhites In East Texas, Donald R. Dietz, R. Montague Whiting Jr., Nancy E. Koerth
Winter Food Habits And Preferences Of Northern Bobwhites In East Texas, Donald R. Dietz, R. Montague Whiting Jr., Nancy E. Koerth
Faculty Publications
During late winter, 1994 and 1995, we investigated food habits and preferences of northern bobwhites (Colinus virginianus; hereafter, bobwhites) collected on forested lands in east Texas. Crops for bobwhites were collected from areas under 3 management regimes, namely intensively managed for bobwhites (QMA) (i.e., tree basal area reduced, annually burned, numerous multi-stage food plots, etc.), extensively managed for timber and wildlife (NBS) (i.e., burned every 3-5 years, scattered 2-stage food plots with corn feeders), and unmanaged for wildlife (i.e., burned every 5-7 years). With years pooled, partridge pea (Cassia fasciculata), Hercules club (Zanthoxylum clava-herculis), and pine (Pinus spp.) seeds, and …
Correlation Between Pollen Dispersion And Forest Spatial Distribution Patterns In The Southeastern United States, I-Kuai Hung
Correlation Between Pollen Dispersion And Forest Spatial Distribution Patterns In The Southeastern United States, I-Kuai Hung
Faculty Presentations
The pollen that falls to the surface at any given point is called the pollen rain. For most regions of the world the pollen rain provides a fairly reliable record of the plants that produce and disperse airborne pollen within a radius of about 30 km from the sampled location. To some extent the local pollen rain can also reflect limited information about the insect-pollinated plants living in a region. For some regions of North America, existing studies of the pollen rain and the regional vegetation associated with those data demonstrate a reliable relationship between these two vegetation aspects. For …

A Comparison Of Presettlement Vegetation And Fire Regimes With Current Patterns In Oak Woodlands And Shrublands Of Sw Oregon, Patricia S. Muir Dr., Paul Hosten Dr.
JFSP Research Project Reports
Fuel reduction efforts on BLM lands in southwestern Oregon are motivated by the need to reduce fire hazard and restore and rehabilitate ecosystems. Successful ecosystem restoration depends, in part, on understanding the target: what ecosystem model is considered natural and healthy for a given area? Oak (Quercus garryana) woodlands and shrublands are two of the most characteristic ecosystems in interior valleys of southwest Oregon, and extensive acreages within these systems are treated annually for fuel reduction. However, these are also two of the least understood ecosystems in the region. We know little about their presettlement attributes, responses to disturbance, or …

A Practical Look At The Variable Area Transect, Solomon Z. Dobrowski, Shannon K. Murphy
Forest Management Faculty Publications
The variable area transect (VAT) is a plotless density estimator that has received little attention in the ecological literature despite having potentially robust estimation properties. VAT allows for density estimations without the lengthy search times associated with other plotless density estimators. In spite of this, little has been written about the effect of varying transect widths on its density estimation properties or on the practical implementation of the VAT in field settings. An artificial population sampler was used to examine the effect of transect width on density estimates obtained using the VAT. Three transect widths were chosen corresponding to the …

Five Years Of Change In An Old-Growth Pine-Hardwood Remnant In Ashley County, Arkansas, Don C. Bragg
Five Years Of Change In An Old-Growth Pine-Hardwood Remnant In Ashley County, Arkansas, Don C. Bragg
Journal of the Arkansas Academy of Science
The Levi Wilcoxon Demonstration Forest near Hamburg, Arkansas is an industrially-owned remnant of old-growth pine and hardwoods. Some of the loblolly (Pinus taeda L.)and shortleaf (Pinus echinata Mill.)pine in this stand are over 200 years old, and numerous individuals exceed 90 cm in diameter and 30 m in height. A2000 survey of a portion of this tract found that 27 tree species contributed an average of387.5 live stems/ha and 31.8 m2 /ha of basal area. An inventory of the same plots in2006 yielded noticeable declines in density (now down to 342.5 stems/ha) and basal area (now 28.2 m2 /ha). Much …

We argue that two problems weaken the claims of those who link corruption and the exploitation of natural resources. The first is conceptual. Studies that use national level indicators of corruption fail to note that corruption comes in many forms, at multiple levels, and may or may not affect resource use. Without a clear causal model of the mechanism by which corruption affects resources, one should treat with caution any estimated relationship between corruption and the state of natural resources. The second problem is methodological: Simple models linking corruption measures and natural resource use typically do not account for other …
A Comparison Of Logging And Fire Disturbance On Biophysical Attributes Of The Northern Jarrah Forest, Alexander W. Watson
A Comparison Of Logging And Fire Disturbance On Biophysical Attributes Of The Northern Jarrah Forest, Alexander W. Watson
Theses: Doctorates and Masters
Ecologically sustainable forest management (ESFM) serves dual purposes: 1) to ensure the conservation of biodiversity, and 2) in production forest (forest managed for the production of timber and woodchips), to maintain an economically viable timber industry in perpetuity. A central axiom of ESFM is that any manipulation of a forest ecosystem should emulate the `natural' disturbance patterns of the forest. This is based on the assumption that forest communities have evolved with endogenous disturbance regimes and will be better able to cope if exogenous disturbance (e.g., logging) remains within natural levels and spatial and temporal bounds of intensity. The objective …
