Forest Diversity And Disturbance: Changing Influences And The Future Of Virginia’S Forests, Christine J. Small, James L. Chamberlain
Forest Diversity And Disturbance: Changing Influences And The Future Of Virginia’S Forests, Christine J. Small, James L. Chamberlain
Virginia Journal of Science
The Virginia landscape supports a remarkable diversity of forests, from maritime dune woodlands, swamp forests, and pine savannas of the Atlantic Coastal Plain, to post-agricultural pine-hardwood forests of the Piedmont, to mixed oak, mesophytic, northern hardwood, and high elevation spruce-fir forests across three mountain provinces in western parts of the state. Virginia’s forests also have been profoundly shaped by disturbance. Chestnut blight, hemlock woolly adelgid, emerald ash borer, and other pests have caused declines or functional extirpation of foundation species. Invasive plants like multiflora rose, Oriental bittersweet, and Japanese stiltgrass threaten both disturbed and intact forests. Oaks and other fire-dependent …
Using Choice Experiment Valuation Methods To Measure Public Preference For A New National Park In Maine, Alexander G. Wilsterman
Using Choice Experiment Valuation Methods To Measure Public Preference For A New National Park In Maine, Alexander G. Wilsterman
Journal of Environmental and Resource Economics at Colby
With global population increasing faster than ever, the need to protect land from development is at an all-time high. This paper seeks the measure the public preference for a new national park located in northern Maine. A national park will both protect the land and inject a much-needed economic stimulus to the surrounding communities. The study uses the choice experiment valuation method to quantify its results. Through this revealed preference we can quantify which characteristics are most important to the public so that these characteristics may be considered if the project is ever approved.
Golf Courses In Maine: Land Type Valuation Versus A Hedonic Pricing Analysis, Gregory Ladd, Jason Buco
Golf Courses In Maine: Land Type Valuation Versus A Hedonic Pricing Analysis, Gregory Ladd, Jason Buco
Journal of Environmental and Resource Economics at Colby
Many studies have been conducted analyzing the economic impact of golf courses on the local communities. These studies examine economic impacts of tournaments, endorsements, and vacation expenses of the major golf courses in the United States. However, there is little research conducted on the environmental impact of Golf courses, specifically in Maine. This paper performs a hedonic pricing analysis using housing prices in proximity to golf courses and compares it to the valuation of various land types in Maine. Housing prices were collected in the towns of Auburn, and North Yarmouth both near and distant from the local golf course. …
Cost Benefit Analysis Of Café Standards Compared To The Alternative Fuel/Carbon Tax, Brian Levinson
Cost Benefit Analysis Of Café Standards Compared To The Alternative Fuel/Carbon Tax, Brian Levinson
Journal of Environmental and Resource Economics at Colby
The Cafe Standards were introduced in 1975 following the Oil Embargo. The goals of this program were simple. To reduce co2 emissions in vehicles by increasing a mandatory average mpg level for car manufacturers in the United States. Recently, in 2012, the Obama Administration set new Cafe Standard requirements for car manufacturers. By 2025, all new cars on the road in the United States must average 54.5 miles per gallon, which would double the current 27 mpg average in place right now. While the intentions of this policy are to reduce co2 emissions while at the same time increasing savings …
The Economics Of The Audubon Society's Sanctuary Program For Golf Courses, Dan Hyszczak
The Economics Of The Audubon Society's Sanctuary Program For Golf Courses, Dan Hyszczak
Journal of Environmental and Resource Economics at Colby
Millions of people play golf every year, and in 2011 Golf Courses gained $22 billion dollars in revenue. This statistic combined with golf’s inherent place in the natural environment lead to questions of value and development for golf course owners. In 1991, The Audubon Society created their Cooperative Sanctuary Program for Golf Courses (ACSP) to promote environmentally sustainable practices for golf courses and to recognize the courses that are the most environmentally in both the United States and around the world.
This paper builds off of prior research that connects golf course beauty with revenue by examining the effects of …
Preferences For Coral Reef And Fishery Management In Okinawa, Japan, Nils Carlson
Preferences For Coral Reef And Fishery Management In Okinawa, Japan, Nils Carlson
Journal of Environmental and Resource Economics at Colby
This study is an example of how a nonmarket valuation method – a choice experiment – can be used to influence and guide ecosystem conservation efforts. Using a choice experiment survey, this study estimates the willingness to pay (WTP) for certain hypothetical attributes of a restored and conserved coral reef in Okinawa, Japan. I find that an increase in the amount of fish available to catch in ten years as well as an increase in the extent and health of the coral reefs and the number of marine biodiversity found in the Okinawan waters after ten-years, both positively affect respondent’s …

Radiocarbon Isotopic Classification Of Deep Tropical Forest Soils, Brooke Butler, Karis J. Mcfarlane, Jennifer Pett-Ridge, Katherine A. Heckman
Radiocarbon Isotopic Classification Of Deep Tropical Forest Soils, Brooke Butler, Karis J. Mcfarlane, Jennifer Pett-Ridge, Katherine A. Heckman
STAR Program Research Presentations
Tropical forest soils have an important role in global carbon (C) stocks. Small changes in the cycling of C could drastically affect atmospheric carbon dioxide (CO2) concentrations and active cycling of carbon in a forest community. Currently, little is understood of how tropical forest soils will respond to the increasing global temperatures. To examine the effects of warming/ drought on losses of older versus younger soil C pools, we implemented radiocarbon (14C) isotopic characterization of various soil plot samples and depths from the Luquillo Experimental Forest, Puerto Rico. 14C was measured using Accelerated Mass Spectrometry (AMS) from catalytically condensed carbon …
Habitat Use By Spruce Grouse In A Fragmented System, Laurel A. Hill
Habitat Use By Spruce Grouse In A Fragmented System, Laurel A. Hill
All NMU Master's Theses
The spruce grouse is a boreal obligate species that has been protected in Michigan since 1915 (Ammann 1963). Despite protection, the status of spruce grouse is uncertain in Michigan and other parts of the Midwest, and there have been few attempts at large-scale surveys or monitoring (Williamson et al. 2008). I studied a population of spruce grouse near the southern edge of their range on the Yellow Dog Plains in Marquette County, Michigan.
I investigated fecal pellet counts as a possible method to assess spruce grouse presence and habitat use. My results validated the use of fecal pellet occurrence as …
Is Chir Pine Displacing Banj Oak In The Central Himalaya? Socioeconomic Implications For Local People And The Conservation Of Oak Forest Biodiversity, Ankush Nautiyal
Is Chir Pine Displacing Banj Oak In The Central Himalaya? Socioeconomic Implications For Local People And The Conservation Of Oak Forest Biodiversity, Ankush Nautiyal
Graduate Theses and Dissertations
Various studies have suggested that chir pine (Pinus roxburghii) is replacing banj oak (Quercus leucotrichophora) in the Central Himalaya. Five sites with three different types of forests (banj oak, chir pine and mixed oak-pine) were sampled to compare the diversity of their vegetation and to assess the impact of this ongoing conversion on biodiversity. Soil samples collected from oak and pine forests were analyzed and compared. In addition, dendrochronology was used to obtain age estimates of chir pine and to understand the growth response of this species to precipitation. Also, samples of ectomycorrhizal fungi were collected in the form of …
Exploration Of Spatial And Temporal Changes In Trophic Status Of Lakes In The Northern Temporal Forest Biome Using Remote Sensing, Aleksey Paltsev
Exploration Of Spatial And Temporal Changes In Trophic Status Of Lakes In The Northern Temporal Forest Biome Using Remote Sensing, Aleksey Paltsev
Electronic Thesis and Dissertation Repository
There is a critical need for detailed surveys of lakes covering large spatial (>100 km2) and temporal scales (decades) to determine if there is an increase in the magnitude and frequency of phytoplankton blooms. Remote sensing was used to: (1) develop a regression model that relates chlorophyll a (chl-a) as a proxy of lake phytoplankton biomass to Landsat TM and ETM+ optical reflectance (r2=0.85, p

Taking Root: An Analysis Of The Best Method For Active Forest Regeneration In The Cloud Forest, Charlotte Startin
Taking Root: An Analysis Of The Best Method For Active Forest Regeneration In The Cloud Forest, Charlotte Startin
Independent Study Project (ISP) Collection
The cloud forest is a biodiversity hotspot and provides many vital ecological and economic services. Unfortunately, deforestation for pastures in the lower montane cloud forest is high. Many pastures become abandoned, leaving highly disturbed open areas of land where natural forest regeneration is poor. Human intervention to encourage ecological restoration is very important to re-establish the proper structure and functioning of the ecosystem. Forest regeneration projects are rare and often unsuccessful, which is why increased knowledge and skills of successful and practical methods for assisted regeneration are needed. The Inti Llacta Reserve in the Pichincha province in Ecuador protects a …

Efficacy Of Dormant Season Herbicide Application On Control Of Japanese Honeysuckle (Lonicera Japonica) For Habitat Restoration In Kentucky, Jason L. Weese
Efficacy Of Dormant Season Herbicide Application On Control Of Japanese Honeysuckle (Lonicera Japonica) For Habitat Restoration In Kentucky, Jason L. Weese
Theses and Dissertations--Forestry and Natural Resources
Kentucky’s disappearing native grassland communities provide habitat for native flora and fauna. A study was conducted to compare the efficacy of herbicides in control of the invasive Japanese honeysuckle (Lonicera japonica) applied at times when most native species are dormant. Six herbicide mixtures (glyphosate, glyphosate + imazapyr, glyphosate + imazapic, imazapyr, triclopyr + difluphenzopyr, and metsulfuron + difluphenzopyr) were applied in three seasons to assess the effect of application timing of each mixture on honeysuckle control. Herbicides were applied with a CO2 pressurized sprayer at three sites in a randomized complete block design. Pretreatment sampling indicated that …
Effects Of Prescribed Fire On Upland Plant Biodiversity And Abundance In Northeast Florida, Peter D. Maholland
Effects Of Prescribed Fire On Upland Plant Biodiversity And Abundance In Northeast Florida, Peter D. Maholland
UNF Graduate Theses and Dissertations
Terrestrial ecosystems in the southeastern United States have evolved with fire as a common disturbance and as a result many natural communities require the presence of fire to persist over time. Human development precludes natural fires from occurring within these communities; however, prescribed fire is considered to be a critical tool in the effort to restore fire-dependent ecosystems after decades of fire exclusion. Direct effects of fire on individual floral and faunal species as well as benefits to biodiversity at the landscape (gamma diversity) level have largely been supported in previous research. However, information on the effects of natural and …
