Public Land Management Values: A Delphi Study Of Austrian And Pacific Northwest United States Recreation Resource Managers, Jessie Meybin
Public Land Management Values: A Delphi Study Of Austrian And Pacific Northwest United States Recreation Resource Managers, Jessie Meybin
Graduate Theses, Dissertations, and Problem Reports
There is a continuing global increase in recreational visitor use of public land. This rise in visitation can be a good thing if a proactive management plan utilizing strong methodology to anticipate impacts to an area and sustain its natural and social resources is in place. Although a wide spectrum of issues is presented to each management, few of the concepts are new to any of the administrators. With increasing duties, newly emerging concerns, and decreasing time, there is little room or patience for error concerning the implementation of any management derivatives or techniques. If the existing research on all …
Manufacture And Properties Of Thermoplastic Starch Biocomposites, Charlie A. Collins Ii
Manufacture And Properties Of Thermoplastic Starch Biocomposites, Charlie A. Collins Ii
Graduate Theses, Dissertations, and Problem Reports
Bio-composites have attracted considerable attention from the industry as potential substitutes for petroleum-derived composites. Starch is a potential candidate because it is biodegradable and is readily available sustainable polymer from agriculture resources. However, it is not easy to process like petroleum-derived polymers because of the lack of defined melting point and is sensitive to high humidity with poor mechanical properties. This study evaluated the processability of starch, lignin and pulp fibers using a BrabenderRTM Torque Rheometer. Type of starch exerted great influence on processability. Gelation characteristics of the four composite mixtures correlated with starch type. Amylose containing composite mixtures (#1 …
Investigating Changes In Productivity Of An Old Growth Juniperus Stand: A Physiological And Isotopic Approach, Scott E. Spal
Investigating Changes In Productivity Of An Old Growth Juniperus Stand: A Physiological And Isotopic Approach, Scott E. Spal
Graduate Theses, Dissertations, and Problem Reports
Forest ecosystems play a central role in the global carbon cycle and are a major part of the terrestrial carbon sink. For more accurate predictions of terrestrial C sequestration models require a mechanistic understanding of how carbon cycling in trees and forests responds to atmospheric CO 2, temperature, and precipitation. With this comes a need for a greater understanding of the physiological mechanisms involved with changes in forest productivity as trees and forests age. This research used an old growth stand of Juniperus virginiana (Eastern red cedar) in the Central Appalachian Mountains of West Virginia to examine how carbon assimilation …
Market Perceptions For Expanded Opportunities Of Central Appalachian Hardwoods, Liberty Olea Moya
Market Perceptions For Expanded Opportunities Of Central Appalachian Hardwoods, Liberty Olea Moya
Graduate Theses, Dissertations, and Problem Reports
This study investigated how to improve the market potentials of Appalachian hardwoods, specifically within West Virginia. Some Appalachian hardwoods could serve as alternative species for producing various value-added wood-based products. Efficient utilization of these species can lead to reduced manufacturing and consumer costs of major hardwood products. The main objectives of the study included: identifying the major products derived from Appalachian hardwoods, evaluating current and future market trends, and identifying the potential for using hickory as a substitute material in wood products. Additionally, factors that influence both local and international community's wood product purchasing decisions (e.g. price, eco-label certifications, image, …
Evaluation Of Tree Growth And Chemical, Physical And Biochemical Soil Properties Of Two Reclaimed Surface Mines In West Virginia, Calene B. Thomas
Evaluation Of Tree Growth And Chemical, Physical And Biochemical Soil Properties Of Two Reclaimed Surface Mines In West Virginia, Calene B. Thomas
Graduate Theses, Dissertations, and Problem Reports
Advancements in technology and coal mining methods have accelerated the disturbance of valuable contiguous deciduous forests in the Appalachian region. In many instances, mountaintop mining has converted large expanses of forested mountaintops to rolling pasture and hay land that have been left abandoned to revert to shrub land dominated by invasive nonnative species. Due to excessive soil compaction and heavy herbaceous cover, natural plant community succession from planted grasslands to hardwood forests is slow. Recently, efforts are being made to re-establish hardwood forests on mined land through careful spoil and amendment selection, and placement and planting of appropriate herbaceous and …
Efficacy Of Varying Rates Of Herbicide And Surfactant For The Control Of Understory Oriental Bittersweet (Celastrus Orbiculatus Thunb.) Plants In An Appalachian Hardwood Forest, Terry L. Burhans Jr.
Efficacy Of Varying Rates Of Herbicide And Surfactant For The Control Of Understory Oriental Bittersweet (Celastrus Orbiculatus Thunb.) Plants In An Appalachian Hardwood Forest, Terry L. Burhans Jr.
Graduate Theses, Dissertations, and Problem Reports
Oriental bittersweet (Celastrus orbiculatus) is an invasive climbing, twining vine that can grow up into the forest canopy effectively inhibiting growth and light exposure on affected trees. A local landowner who had treated bittersweet with various rates of a glyphosate-based herbicide claimed that higher than recommended rates of herbicide were needed to effectively control the invasive plant. This study was established to assess the validity of this claim and to explore the interaction of glyphosate and surfactant effects on the efficacy of bittersweet control. The goal was to determine an ideal treatment of herbicide and surfactant rates for the effective …
Landowner Outreach Education Project Evaluation: Connecting New Family Forest Owners With The Professional Forestry Community, Megan E. Mccuen
Landowner Outreach Education Project Evaluation: Connecting New Family Forest Owners With The Professional Forestry Community, Megan E. Mccuen
Graduate Theses, Dissertations, and Problem Reports
The majority of West Virginia's forested land is owned by private family forest owners. These individually owned woodlands significantly impact the whole landscape. Connecting with this population and linking them with services and organizations that offer support is essential as these individuals and families establish their ideal woodland. Absentee landowners, land transfers, and increasing industry and development bring to the landscape a high risk for parcelization and fragmentation. With knowledge and forest management information, many woodland owners can improve the overall health, sustainability, and productivity of these lands.;One of the challenges in promoting sustainable forestry is finding ways to connect …
Forest Regeneration: Perceptions Of Natural Resource Professionals In West Virginia, Ellen Lee Voss
Forest Regeneration: Perceptions Of Natural Resource Professionals In West Virginia, Ellen Lee Voss
Graduate Theses, Dissertations, and Problem Reports
It has generally been assumed that natural hardwood regeneration in West Virginia after a timber harvest or other disturbance will be abundant and successful. However, changes that are being observed in the seedling and sapling components of forest stands suggest that problems may exist with regeneration of desirable species. Factors affecting regeneration have been the topic of conversation among foresters and other natural resource professionals for years. To address the need for more information about this issue, we conducted a mail survey of natural resource professionals (NRPs) in West Virginia. The objectives of the survey were to determine how they …
