The Effects Of Environmental Restoration On Housing Prices In Northern Colorado, Jack Steketee Jan 2020

The Effects Of Environmental Restoration On Housing Prices In Northern Colorado, Jack Steketee

Capstones and Honors Theses

Hedonic valuation is a method of using a market, such as the housing market, to estimate the value of non-market goods. An example of a non-market good we might want to value is environmental quality. Proper valuation of the environment can help make informed policy decisions, as well as help better protect or restore it. We use the hedonic valuation model This research uses data from a housing market in Colorado to estimate the value homeowners place on an environmental restoration project. We hypothesized that overall, we would see an increase in home value after a restoration project was completed …

Integrated Techno-Economic And Life Cycle Analyses Of Biomass Utilization For Value-Added Bioproducts In The Northeastern United States, Yuxi Wang

Graduate Theses, Dissertations, and Problem Reports

A multi-stage spatial analysis was first conducted to select locations for lignocellulosic biomass-based bioproduct facility, using Geographical Information System (GIS) spatial analysis, multi-criteria analysis ranking algorithm, and social-economic assessment. A case study was developed to determine locations for lignocellulosic biorefineries using feedstocks including forest residue biomass and three energy crops for 13 states in the northeastern United States. In the entire study area, 11.1% of the counties are high-suitable, 48.8% are medium-suitable for biorefinery siting locations. A non-parametric analysis of cross-group surveys showed that preferences on biorefinery siting are homogeneous for experts in academia and industry groups, but people in …


Leaf Angle And Leaf Stomata Responses To Experimental Drought In Quercus Velutina And Acer Saccharum, Brittany Nichole Casey Jan 2020

Leaf Angle And Leaf Stomata Responses To Experimental Drought In Quercus Velutina And Acer Saccharum, Brittany Nichole Casey

Graduate Theses, Dissertations, and Problem Reports

The possibility of increased severity and frequency of drought conditions, as a result of global climate variability, greatly complicates our ability to forecast future forest functions such as productivity and carbon sequestration. Assessing how tree species vary in their response to drought can aid in predicting the impact on forest ecosystems as a whole. Throughfall exclusion (TfE) experiments are potentially useful tools to simulate realistic drought conditions within intact forest ecosystems. We employed a TfE experiment during the 2018 growing season within the WV Land Trust’s Elizabeth’s Woods Nature Preserve, near Morgantown, WV, to assess the leaf angle and leaf …


Family Forest Owners Satisfaction With Timber Transactions, Jeffrey M. Lee Jan 2020

Family Forest Owners Satisfaction With Timber Transactions, Jeffrey M. Lee

Graduate Theses, Dissertations, and Problem Reports

Forest industries in the eastern U.S. rely heavily on family forest owners to supply fiber needs for their mills. As of 2017, 79 percent of West Virginia is classified as forestland and of this roughly 86.5 percent is privately owned. With such a heavy reliance on wood from private forest lands, family forest owner satisfaction is extremely important if companies want to continue harvesting or working with these landowners in the future.

Timber transactions are complex. No two timber transactions are exactly the same. They often involve many different parties apart from the landowner. Site conditions, land cover, and landowner …


Relating Recharge Mechanisms To Chemical Changes In An Updip Appalachian Coal Mine Discharge: A Case Study From Lambert Run, West Virginia, Matthew Lewis Bell Jan 2020

Relating Recharge Mechanisms To Chemical Changes In An Updip Appalachian Coal Mine Discharge: A Case Study From Lambert Run, West Virginia, Matthew Lewis Bell

Graduate Theses, Dissertations, and Problem Reports

Impaired drainage from active and abandoned mines degrades the water quality of receiving streams and aquifers. Coal mine drainage (CMD) has been studied for decades in Appalachia, but unknowns and uncertainties are still present, including the influence of mine hydrogeology on the outflow chemistry of above-drainage mines. To evaluate the influence of recharge type on above-drainage mine chemistry, samples were collected every two weeks at a CMD outflow treatment system in Harrison County, West Virginia.

Samples were collected to measure geochemical changes taking place in the mine workings and along the flowpath of the passive treatment system. Samples were divided …


Advancing Quantitative Understanding Of Escherichia Coli Concentrations In A Contemporary Mixed Land-Use Watershed, In West Virginia, Usa, Fritz Petersen Jan 2020

Advancing Quantitative Understanding Of Escherichia Coli Concentrations In A Contemporary Mixed Land-Use Watershed, In West Virginia, Usa, Fritz Petersen

Graduate Theses, Dissertations, and Problem Reports

A scarcity of field-based research investigating the relationships between E. coli (fecal matter) concentration, suspended particulate matter (SPM; including size distribution), physicochemical parameters (water temperature, pH, SPC, DO, chloride) and land use practices and the importance of these relationships, particularly for human health, policy makers, and water resource managers, provided the impetus for this research. A 22-site, nested-scale, experimental watershed study design was implemented to investigate E. coli concentrations and the aforementioned relationships in a contemporary mixed land use watershed in the Appalachian region of the eastern United States. Results from a reduced (n=4 sites) study showed SPM in the …


Microbial Responses To Unconventional Oil And Gas Development May Alter Ecosystem Function In Headwater Streams, Rachel Michaels Jan 2020

Microbial Responses To Unconventional Oil And Gas Development May Alter Ecosystem Function In Headwater Streams, Rachel Michaels

Graduate Theses, Dissertations, and Problem Reports

The demand for natural gas, and the need for efficient extraction, has led to the development of unconventional oil and natural gas (UOG) techniques. Due to the novelty of UOG, the potential impacts to freshwater ecosystems are not fully understood. We used a dual pronged approach to study the effects of UOG development on microbial biodiversity and function via a laboratory microcosm experiment and a survey study of streams with and without UOG development within their watersheds. The laboratory microcosm study simulated stream contamination with produced water, a byproduct of UOG operation, using sediment collected from one high water-quality stream …


Spawning Characteristics Of Yellow Perch During Periods Of Water Level Fluctuations In A Hydropower Reservoir, Kyle J. Matt Jan 2020

Spawning Characteristics Of Yellow Perch During Periods Of Water Level Fluctuations In A Hydropower Reservoir, Kyle J. Matt

Graduate Theses, Dissertations, and Problem Reports

Water level fluctuations alter reservoir ecosystems causing direct and indirect effects on fish populations. The dewatering of eggs, a direct impact of lake level drawdowns, can affect reproductive success of species that spawn in littoral zones, such as Yellow Perch. I examined relationships between water level fluctuations and spawning characteristics of Yellow Perch in a Central Appalachian hydropower reservoir, where water levels were permitted to be drawn down to 4 m and 2.1 m below the full pool elevation in March and April, respectively. Daily presences of egg masses were recorded on artificial spawning structures at two sites for the …


A Spatially Distributed Investigation Of Stream Water Temperature In A Contemporary Mixed-Land-Use Watershed, Jason P. Horne Jan 2020

A Spatially Distributed Investigation Of Stream Water Temperature In A Contemporary Mixed-Land-Use Watershed, Jason P. Horne

Graduate Theses, Dissertations, and Problem Reports

Stream water temperature is an important physical variable that influences many biological and abiotic water quality processes. The land-use/land-cover (LULC) types and corresponding variability in stream water temperature (Tw) processes in contemporary mixed-land-use watersheds necessitate research to advance management and policy decisions. Water temperature was analyzed from 21 gauging sites using a nested-scale experimental watershed study design. Results showed that forested land use was significantly negatively correlated (α = 0.05) with mean and maximum Tw. Agricultural land use was significantly positively correlated (α = 0.05) with maximum Tw except during the spring season. Mixed development and Tw were significantly correlated …


Habitat Stability In Appalachian Headwater Systems And Potential Impacts On Brook Trout Populations, Zac F.W Zacavish Jan 2020

Habitat Stability In Appalachian Headwater Systems And Potential Impacts On Brook Trout Populations, Zac F.W Zacavish

Graduate Theses, Dissertations, and Problem Reports

The impact climate change will have on the habitat for Brook Trout (Salvelinus fontinalis) could directly impact key demographic characteristics. Traditionally, broad-scale studies of climate change effects on the family Salmonidae focus on the thermal shifts predicted over the next century. While some studies shed light onto other variables such as biotic interactions, flow regime, and disturbance, the significance of the climate-trout interaction is not always observed. With the high degree of influence climate cycles can have on habitat and channel morphology, this study aimed to highlight temporal habitat shifts to begin addressing climate-habitat interaction. By studying habitat distribution …


Dendroclimatic Analysis And Site Index Modeling Of Central Appalachian Red Spruce, Eric L. Yetter Jan 2020

Dendroclimatic Analysis And Site Index Modeling Of Central Appalachian Red Spruce, Eric L. Yetter

Graduate Theses, Dissertations, and Problem Reports

Red spruce (Picea rubens) was historically an important and dominant timber species in the central Appalachian mountain range. The tree species is now found in a small fraction of its original home range. Threatened and endangered organisms such as the Cheat Mountain Salamander (Plethodon nettingi) rely on red spruce associated forests for survival. Recent concerns including air pollution and climate change may threaten the health of remaining red spruce populations.

I used dendrochronology data to conduct historic dendroclimatic analyses and construct future growth projections for red spruce throughout the central Appalachians. My research involves the use of tree core data …


Disturbance Related To Unconventional Oil And Gas Development In The Appalachian Basin, Kevin Jordan Harris Jan 2020

Disturbance Related To Unconventional Oil And Gas Development In The Appalachian Basin, Kevin Jordan Harris

Graduate Theses, Dissertations, and Problem Reports

Little research has been done on the land cover change of unconventional oil and gas (UOG) wells across the Appalachian basin. In the last decade, UOG development has increased drastically across the region. Permitted well data from 2007 to 2017 were assembled into a geospatial database and analyzed with current aerial imagery to determine the activity of permitted wells in Ohio, Pennsylvania, and West Virginia. To capture all disturbance related to UOG development, a 25-hectare buffer was placed around each active well as the study extent. A supervised classification approach was used to determine the pre-development and post-development landcover across …
