Harvested Log Damage And Value Loss Associated With Two Ground-Based Harvesting Systems In Central Appalachia, Michael R. Vanderberg
Harvested Log Damage And Value Loss Associated With Two Ground-Based Harvesting Systems In Central Appalachia, Michael R. Vanderberg
Graduate Theses, Dissertations, and Problem Reports
Damage is often seen as an important consideration when conducting partial harvests in hardwood stands, as excessive damage to residual trees will significantly reduce the potential value of the residual stand. Damage to harvested logs, especially hardwood saw and veneer logs can be an even more important concern relative to value loss associated with log degrade. The log damage and value loss were examined by harvesting system, felling function, species, and damage type in central Appalachia. Observations were made of all grade logs during the felling, skidding, decking/sorting, and loading functions of the harvesting operations. Saw logs or veneer logs …
Relations Of Nesting Behavior, Nest Predators, And Nesting Success Of Wood Thrushes (Hylocichla Mustelina) To Habitat Characteristics At Multiple Scales, Gary E. Williams Jr.
Relations Of Nesting Behavior, Nest Predators, And Nesting Success Of Wood Thrushes (Hylocichla Mustelina) To Habitat Characteristics At Multiple Scales, Gary E. Williams Jr.
Graduate Theses, Dissertations, and Problem Reports
During 1998--2000, I examined the relationship between the reproductive success of a declining Neotropical migrant songbird, the wood thrush ( Hylocichla mustelina), and surrounding habitat within the highly forested region encompassing the northwestern portion of the Monongahela National Forest, West Virginia, USA. I measured nest fate, food delivery rates, and nest attendance rates of 56 videotaped nests and then related these variables to habitat measured at three concentric scales: nest site (11.3 m radius), territory (100 m), and landscape (1000 m). Predation was the most common source of failure (23 of 26 failed nests), and southern flying squirrels ( Glaucomys …
Organic Carbon And Fertility Of Forest Soils On The Allegheny Plateau Of West Virginia, Anthony Blaine Jenkins
Organic Carbon And Fertility Of Forest Soils On The Allegheny Plateau Of West Virginia, Anthony Blaine Jenkins
Graduate Theses, Dissertations, and Problem Reports
Soil series occurring above 1020 m in elevation in the Monongahela National Forest in West Virginia were sampled and analyzed for soil organic and soil microbial biomass carbon as well as various fertility parameters. Additionally, vegetative biomass estimates were made at the sampling sites. The soil series sampled (established and tentative) are frigid, well and moderately-well drained inceptisols and spodosols, covered by northern hardwood or spuce-dominated forests. The purpose of the work was to document soil organic carbon (SOC), vegetative organic carbon (VOC), and soil microbial biomass carbon (SMBC) of selected horizons, and nutrient stock ranges for these extensive series, …
Effects Of Edge And Coarse Woody Debris On Small Mammal Communities In Riparian And Upland Habitats In Northern West Virginia, Joseph Daniel Osbourne
Effects Of Edge And Coarse Woody Debris On Small Mammal Communities In Riparian And Upland Habitats In Northern West Virginia, Joseph Daniel Osbourne
Graduate Theses, Dissertations, and Problem Reports
The effects on biological communities of human-induced disturbances such as road construction for logging and military activities are a topic of much controversy in modern society. Furthermore, the response of small mammal communities to edge and coarse woody debris (CWD) volume in riparian and upland habitats of the central Appalachian Mountains has received little attention. The objectives of this study were to: (1) Perform a faunal survey of the Camp Dawson Collective Training Area in Preston County, West Virginia with an emphasis on rare and endangered species, (2) Estimate small mammal abundance, diversity, and condition in response to CWD manipulation, …
Design And Implementation Of Web-Based Gis For Forest Fragmentation Analysis, Fei Wang
Design And Implementation Of Web-Based Gis For Forest Fragmentation Analysis, Fei Wang
Graduate Theses, Dissertations, and Problem Reports
The advantages and limitations of current web GIS software for forest fragmentation information and analysis functionality were investigated using Landsat Thematic Mapper data of 1987 to 1999 for a test site in northern West Virginia. ESRI's ArcIMS technology was used to build a Web-based forest fragmentation analysis system to query, represent, and analyze the status of forest fragmentation using landscape metrics. Both ArcIMS HTML and Java fragmentation analysis tools were constructed. The web GIS was evaluated with respect to accessibility, navigation, interactive cartographic functionality, and spatial analysis functionality. The current ArcIMS approach was found to offer only limited support for …
Comparison Of Herpetofaunal Species Composition And Response To Edge On The Camp Dawson Collective Training Area, Preston County, West Virginia, Amy B. Spurgeon
Comparison Of Herpetofaunal Species Composition And Response To Edge On The Camp Dawson Collective Training Area, Preston County, West Virginia, Amy B. Spurgeon
Graduate Theses, Dissertations, and Problem Reports
Herpetofaunal species composition, abundance, and diversity were evaluated on the Camp Dawson Collective Training Area, Preston County, West Virginia, as a requirement of the Sikes Act (16 USC 670a et seq.), Army Regulation 200-3, and Department of Defense Instruction 4715.3. Herpetofauna were sampled using pitfall traps with drift fences and double-ended funnel traps, and also from area searches. Redback salamander (Plethodon cinereus), red-spotted newt (Notophthalmus v. viridescens ), eastern American toad (Bufo a. americanus), and wood frog (Rana sylvatica) were most common in pitfall arrays; mountain dusky salamander (Desmognathus ochrophaeus), Appalachian seal salamander (Desmognathus m. monticola), and redback salamander were …
Nest-Site Resources For Cavity-Nesting Birds In The Southern Allegheny Mountain Forests Of West Virginia, Harry A. Kahler
Nest-Site Resources For Cavity-Nesting Birds In The Southern Allegheny Mountain Forests Of West Virginia, Harry A. Kahler
Graduate Theses, Dissertations, and Problem Reports
Cavity-nesting birds may be negatively impacted by a lack of proper nesting sites. Southern Allegheny Mountain forests of West Virginia are unique due to the juxtaposition and diversity of forest cover types. Management must focus on monitoring wildlife population levels as well as habitat requirements within each cover type. Cavity tree abundance significantly differed among central hardwood (x¯ = 16.4; SE = 5.3), northern hardwood (x¯ =12.7; SE = 6.8), and boreal forest cover types (x¯ = 7.2; SE = 3.6) ( P < 0.0001). Black locust (Robinia pseudoacacia) and American beech (Fagus grandifolia) were most likely to have tree cavities, yet beech may be influenced by increased mortality from recent outbreaks of beech bark disease initiated by the beech scale insect (Cryptacoccus fagisuga). Nesting bird community density, richness, and abundance do not differ among mature forests of the 3 cover types. Cavity-nesting species dependent on available tree holes were found most in the central hardwoods (P = 0.009). Forest managers should consider landscape level effects, as well as forest stand composition, when recommending silvicultural treatments.
Spatial And Predictive Foraging Models For Gray Bats In Northwest Georgia And A Comparison Of Two Acoustical Bat Survey Techniques, Joshua Begg Johnson
Spatial And Predictive Foraging Models For Gray Bats In Northwest Georgia And A Comparison Of Two Acoustical Bat Survey Techniques, Joshua Begg Johnson
Graduate Theses, Dissertations, and Problem Reports
The federally endangered gray bat (Myotis grisescens) is an obligate, year-round, cavedwelling species. Efforts to protect caves occupied by gray bats have proved beneficial to recovery. Specific gray bat foraging area characteristics also are critical to gray bat population recovery and maintenance. In summer 2000 and 2001, I determined gray bat presence/absence with Anabat II acoustic bat detectors in potential foraging areas near 2 bachelor colonies in northwest Georgia. In 2000, I systematically sampled 213 locations near water sources over an 8.3 x 9.4 km sampling grid that was established over a 5,100 km2 study area. Each sampling point was …
Combined Effects Of Water Chemistry, Canopy Cover, And Stream Size On Benthic Macroinvertebrates Along A Central Appalachian Stream Continuum, Jesse Adam Bopp
Combined Effects Of Water Chemistry, Canopy Cover, And Stream Size On Benthic Macroinvertebrates Along A Central Appalachian Stream Continuum, Jesse Adam Bopp
Graduate Theses, Dissertations, and Problem Reports
I sampled benthic macroinvertebrates along a 25.2 km stream continuum in the Central Appalachian Mountains of West Virginia from May---October 2000. Six components of macroinvertebrate community structure and function were measured: density, biomass, richness, community taxa similarity, feeding group composition, and metric composition. I quantified these components to determine if localized variation in alkalinity and canopy cover would modify stream continuum predictions. Localized variation in alkalinity and canopy cover significantly affected macroinvertebrate structure and function and modified stream continuum predictions. Results indicated that alkalinity was the primary determinant of macroinvertebrate structure and function, and that the effects of canopy cover …
Small Mammal Communities On A Reclaimed Mountaintop Mine/Valley Fill Landscape In Southern West Virginia, Howard Douglas Chamblin
Small Mammal Communities On A Reclaimed Mountaintop Mine/Valley Fill Landscape In Southern West Virginia, Howard Douglas Chamblin
Graduate Theses, Dissertations, and Problem Reports
Mountaintop mine/valley fill is a large-scale form of strip mining whose effects on small mammals had not previously been examined. Small mammals were captured by Sherman trap and drift fence array (pitfall and funnel traps) on 3 treatments representing the mined landscape and intact forests representing the unmined condition. Peromyscus ( P. leucopus and maniculatus) dominated Sherman captures and were the most common array capture. Eastern chipmunks (Tamias striatus), woodland jumping mice (Napaeozapius insignus), woodland voles (Microtus pinetorum), northern short-tailed shrews (Blarina brevicauda), and pygmy shrews (Sorex hoyi) were more common in forest treatments; Peromyscus, house mice (Mus musculus), southern …
