Acorn Foraging As A Means To Explore Human Energetics And Forge Connections To Local Forests, Jeffrey J. Gerwing, Pamela Lockwood, Christopher Uhl

Environmental Science and Management Faculty Publications and Presentations

Jeffrey Gerwing, Pamela Lockwood, and Christopher Uhl describe a rather unusual ecology laboratory/field exercise that utilizes abundant oak habitats of central Pennsylvania. For those readers not blessed with an abundant supply of oaks nearby, perhaps other species could be substituted. The exercise is unusual in two ways. It offers a new undergraduate ecology activity, and it offers opportunities for students to relate other disciplines to their science course.

In "the good old days" of higher education each discipline offered its menu of courses and expected students to make appropriate connections among the courses of their major, minor, and general education. …

Strength Properties Of Juvenile And Mature Wood Of Twelve Families Of Loblolly Pine (Pinus Taeda L.), Elizabeth Lynn Forbes

Electronic Theses and Dissertations

The wood mechanical properties of progeny from twelve open-pollinated parent trees were examined. Six families were from parents which had high wood specific gravity and six were from parents which had low wood specific gravity. Thirty-two-year-old trees, that had been planted at Many, Louisiana, were sampled and juvenile and mature wood test specimens were prepared. Maximum crushing strength, modulus of rupture, modulus of elasticity and wood specific gravity were determined from compression parallel to the grain tests and static bending tests. Maximum crushing strength, modulus of rupture, modulus of elasticity, and specific gravity were found to vary significantly between family …

The Effect Of Using Hemicellulase And Oxidase Successively As Pre-Bleaching Agents For Hardwood Kraft Pulp, Bryan R. Moore

Honors Theses

Environmental concerns have applied pressure on the paper industry to change many erstwhile processes that have traditionally remained unchallenged. One process in particular is pulp bleaching. Elemental chlorine, while effective in bleaching pulp and low in capital cost, is a major environmental threat because of the toxic chlorinated compounds and other dioxins that are generated in mill effluents. With increasing technology and demand, there has been much research devoted to the development of alternate bleaching sequences, whether Elemental Chlorine Free (ECF), which can use Chlorine Dioxide (ClO₂), or Totally Chlorine Free (TC). THe wide acceptance of these bleaching …

Herbicide And Fertilizer Combinations For Newly Planted Loblolly Pine Seedlings On A Flatwoods Site In Southeastern Arkansas: Year Three Results, Jimmie L. Yeiser

Faculty Publications

Herbicide and fertilizer combinations were tested for enhanced loblolly pine (Pinus taeda L.) seedling performance on a chemically prepared, flatwoods site in southeastern AR. Fertilizer treatments were selected combinations of 40,50, and 50 pounds per acre of elemental N, P, or K, respectively. Arsenal+Oust (4 ounces+2 ounces per treated acre) was applied for herbaceous weed control (HWC). One treatment of herbicide or herbicide+ fertilizer was applied per year; the same rate was used for years one (1996) and two (1997). After three growing seasons, the greatest seedling volume resulted from two treatments of HWC+NPK fertilizer. Two treatments of HWC alone …

One-half of all seedlings were fitted with 122-cm tall polyethylene tree shelters, Seedlings were planted 1 year before the initiation of plant water relation measurements. The study was located within the boundary of the Longhorn Army Ammunition Plant, Kamack, TX. The objective of the research was to study the feasibility of artificially regenerating baldcypress along the shores of Caddo Lake. Stomata1 conductance and transpiration …

Preliminary Analysis Of The Management Situation Summary, Wasatch-Cache National Forest, April 1999, United States Department Of Agriculture, Forest Service

Forestry

The National Forest Management Act (NFMA) of 1976 (NFMA P.L. 94-588) required each National Forest to develop National Forest Land and Resource Management Plans (Forest Plans), and to update or "revise" them when conditions have significantly changed or at least every 15 years. The Wasatch-Cache National Forest completed its current Forest Plan in 1985 (USDA Forest Service 1985). To comply with NFMA a revision needs to be completed by the end of 2000. In 1997, Congress prohibited expenditure of funds on formal Forest Plan revision. In 1998 prohibitions were lifted for 14 national forests nationwide. The Wasatch-Cache National Forest was …

Aboveground Production And Nutrient Circulation Along A Flooding Gradient In A South Carolina Coastal Plain Forest, William Conner, Marianne K. Burke, B Graeme Lockaby

Publications

Relative to effects of flooding, little is known about the influence of hydrology-nutrient interactions on aboveground net primary production (NPP) in forested wetlands. The authors found that nutrient circulation and NPP were closely related along a complex physical, chemical, and hydrologic gradient in a bottomland hardwood forest with four distinct communities. Aboveground biomass, NPP, biomass partitioning to stem production, growth efficiency, and soil macronutrient availability were greatest in the flooded zone, possibly because of the stable hydrologic regime. In the wet transition zone, trees were least productive, nutrient use efficiency was highest, and N retranslocation from foliage before abscission was …

The Use Of Tree Shelters In Restoring Forest Species To A Floodplain Delta: 5-Year Results, William Conner, L Wayne Inabinette, Evaden F. Brantley

Publications

Without herbivory control, natural seed sources, and seasonal flood events, recovery of the Pen branch delta in South Carolina to former conditions (prior to thermal discharge) may take many years. To assess the recovery process, seedlings of baldcypress (TuxoLtiurn distichum), water tupelo (Nyssa aquatica), swamp blackgum (Nyssa sylvatica var. biflora), and green ash (Fraxinuspennsylucmicn) were planted in four areas of the delta in 1994. One-half of the seedlings were protected using tree shelters 1.5 m tall. Heights of seedlings were taken after planting and at the end of each growing season from 1994 to 1998. Survival at the end of …

What’S The Monetary Value Of Your Premerchantable Timber?, Steven H. Bullard, Tom Monaghan

Faculty Publications

"Premerchantable" timber is not yet merchantable-in most cases this means the trees are too small to be sold for pulpwood or other commercial products. Sometimes referred to as ''precommercial" or ''immature," timber stands with average tree diameters less than five inches occupy over 50 million acres in the South-an area roughly the size of North and South Carolina combined .

Relationships Of Selected Soil Properties And Community Species Composition In Turkey Hill Wilderness Area In East Texas, Kenneth W. Farrish, Brian P. Oswald

Faculty Publications

-Sixty-nine different stands within 15 different previously managed communities were sampled in what is now the Turkey Hill Wilderness of the Angelina National Forest. Within each stand, 0.04 ha plots were randomly located, and the height, diameter, crown class and species of each tree recorded. Soil samples were collected in two locations within each plot, and the soil type confirmed at plot center. Soil samples were analyzed for selected soil chemical and physical properties. Due to the low occurrence (less than 4 times) of some communities, only six community types were analyzed Analysis of the vegetation and soil data using …

Financial Analysis Of Pruning Combined With Low Density Management Of Southern Yellow Pine In East Texas: An Assessment, Jayson F. Tate, A. Gordon Holley, Leslie A. Dale, Gary D. Kronrad

Faculty Publications

Time study was conducted on pruning of research plots in a IZyear-old loblolly pine (Pinus taeda) plantation thinned to 58 square feet basal area (190 trees) per acre. Pruning times with labor and equipment costs were used to determine per acre and per tree pruning costs. Pruning costs were used to find values necessary to break-even on a pruning investment. Soil expectation value (SEV) calculations were used to compare profitability of management utilizing heavy thinning with pruning to traditional management regimes. Calculations were performed using a current hourly wage of $8.00, stumpage price of $400.00, per thousand board feet (MBF) …

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 …

Management Of Droughty Site: Typic Quartzipsamments, Ecological Considerations, David Kulhavy, W. G. Ross, L. Allen Smith, R. R. Cahal

Faculty Publications

Pine plantations on Typic Quartzipsamments in East Texas are difficult to establish. Forest management options following clearcutting are limited. A 12 year regeneration study of the growth and survival of loblolly, Pinus faeda, L. shortleaf, P. echinata Mill., slash, f. elliofii Engelm and longleaf pines P. pa/u&is Mill. was conducted to determine optimum tree species and treatments for reforestation. With successful regeneration also comes insects and pathogens. Impacts of the Nantucket pine tip moth, Rhyacionia frusfrana, (Comstock) and the Texas leaf-cutting ant, Affa texana, (Buckley) will be discussed in the context of droughty site management.

Changes In Understory Woody Vegetation In Red-Cockaded Woodpecker (Picoides Borealis) Nesting Clusters, W. D. Hacker, W. G. Ross, David Kulhavy

Faculty Publications

Understory woody vegetation in red-cockaded woodpecker nesting clusters located in Pinus taeda (L.) and P. echinara (Mill.) dominated stands were inventoried from December 1986 through January 1987 and later in January 1995 to determine what effects court-ordered management schemes had on the composition, abundance, and diversity of these stands. There was a significant difference (Pin the composition between the first sampling period and the second with species diversity increasing and a change from a
