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

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

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

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

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 …

The Photosynthetic Response Of Northern Red Oak (Quercus Rubra L.) And American Chestnut (Castanea Dentata (Marsh.) Borkh) Under Varying Light Intensity And Weed Competition, Pedro Vitor P. Pereira, Jennifer M. Lesko, Douglass F. Jacobs Dr.

The Summer Undergraduate Research Fellowship (SURF) Symposium

Although widely distributed across Indiana and the United States Midwest, conifer plantations consist largely of non-native species that are of no value to the state’s forest products industry. This project’s goal is to develop science-based protocols and specific silvicultural prescriptions for successfully converting conifer plantations to higher value native hardwoods. Quantifying photosynthesis rate in a plant is an important tool to help us discern the best methods for implementing conifer conversion. Seedlings from two different native species, northern red oak (Quercus rubra L.) and American chestnut (Castanea dentata (Marsh.) Borkh), were distributed among three different silvicultural …

Understory Tree Composition, Diversity And Natural Regeneration Status Of Uluguru Forests In Morogoro- Tanzania, David S. Kacholi

Journal of Humanities and Social Sciences

Most of the studies on tropical forests vegetation have tended to focus on trees with a diameter at breast height (DBH) greater or equal to 10cm, and limited attention has been paid to understory. This study was conducted in Uluguru forests in Morogoro region, Tanzania, with an objective of describing the understory tree composition, diversity and natural regeneration of some threatened species in the seven surveyed forests. Sampling was done in the forests whereby classification of understory was done into three layers: seedling (individuals with height < 1m), small sapling (DBH ≤ 3 cm), and large sapling (3 < DBH < 10 cm) layers. Large saplings were sampled in 20m × 20m plots, while subplots of 5m ×5m and 2m ×2m were placed at the centre of each plot for sampling small saplings and seedlings, respectively. A total of 2119 seedlings, 1798 small saplings, and 2585 large saplings belonging 91, 102, and 104 species, respectively, were recorded. Fabaceae was the most speciosefamily in all the studied compartments, and had higher familial importance value (FIV). The seedling layer had higher tree density than the large and small sapling layers, but the large and small sapling layers were more diverse than the seedling layer (p < 0.05).The species richness in each forest was significantly higher in the understory than overstory layer (p < 0.034); and the pairing was strongly positively correlated (r = 096, p = 0.0003). The Sørensen coefficients of similarities between understory and overstory ranged between 0.53–0.77, and were higher within each forest than among them. All forests revealed to have good regeneration, though it is important to understand that some species unveiled poor or hampered regeneration pattern.In summary, the understory was observed to be speciose than overstory layer; it was dominated by family Fabaceae, and the natural regeneration of the forests were good, however, some species need due attention.

Scaling From Single-Point Sap Velocity Measurements To Stand Transpiration In A Multi-Species Deciduous Forest: Uncertainty Sources, Stand Structure Effect, And Future Scenarios Impacts, Virginia Hernandez-Santana, Adan Hernandez-Hernandez, Matthew A. Vadeboncoeur, Heidi Asbjornsen

All Materials

ABSTRACT

A major challenge in studies estimating stand water use in mixed-species forests is how to effectively scale data from individual trees to the stand. This is the case for forest ecosystems in the northeastern USA where differences in water use among species and across different size classes have not been extensively studied, despite their relevance for a wide range of ecosystem services. Our objectives were to assess the importance of different sources of variability ontranspiration upscaling and explore the potential impacts of future shifts in species composition on forest water budget. We measured sap velocity in five tree species …

Lidar And Machine Learning Estimation Of Hardwood Forest Biomass In Mountainous And Bottomland Environments, Bowei Xue

Graduate Theses and Dissertations

Light detection and ranging (lidar) has been applied in various forest applications, such as to retrieve forest structural information, to build statistical models for identification of tree species, and to monitor forest growth. However, despite significant progress in these areas, the choice of regression approach and parameter tuning remains an ongoing critical question. This study focused on choosing the right spatial generalization level to transform lidar point clouds to 2D images which can be further processed by mature image processing and pattern recognition approaches. It also compared the prediction ability of popular machine learning algorithms applied to aboveground forest biomass …

The Price Of Snow: Albedo Valuation And A Case Study For Forest Management, David A. Lutz, Richard B. Howarth

Dartmouth Scholarship

Several climate frameworks have included the role of carbon storage in natural landscapes as a potential mechanism for climate change mitigation. This has resulted in an incentive to grow and maintain intact long-lived forest ecosystems. However, recent research has suggested that the influence of albedo-related radiative forcing can impart equal and in some cases greater magnitudes of climate mitigation compared to carbon storage in forests where snowfall is common and biomass is slow-growing. While several methodologies exist for relating albedo-associated radiative forcing to carbon storage for the analysis of the tradeoffs of these ecosystem services, they are varied, and they …

Fire, Fuels, And Streams: The Effects And Effectiveness Of Riparian Treatments, Josh Mcdaniel

Joint Fire Science Program Digests

Fire is an important disturbance in riparian systems—consuming vegetation; increasing light; creating snags and debris flows; altering habitat structure; and affecting stream conditions, erosion, and hydrology. For many years, land managers have worked to keep fire out of riparian systems through the use of buffers. A number of projects funded by the Joint Fire Science Program are shedding light on the dynamics of fire in riparian systems. Recent research and field practice have shown that (1) riparian treatments can be beneficial and are not as risky as previously thought; and (2) riparian treatments need the “Goldilocks” prescribed fire—not too hot …

Impact Of Using Different Stocking Rates Of Goats Under Pine Plantation On Plant Species Occurrence And Animal Productivity, Anthony S. Kumi, India Howard, Ronald C. Smith, Nar Gurung, Alphonso Elliott

Professional Agricultural Workers Journal

Abstract

The study assessed the impact of using different stocking rates of goats under pine plantation on plant species occurrence and animal productivity. It was conducted on an 11 year-old loblolly pine plantation site in Epes, Alabama from July to October 2011. Thirty-six Kiko crossbred male goat kids of 4 to 5 months of age were assigned to different stocking rates, namely, low (4 goats/acre), medium (8 goats/acre), and high (12 goats/acre) with three replications each. Forage composition, animal daily gain (ADG) and blood urea nitrogen (BUN) were monitored. Bahia grass (Paspalum notatum) was the most dominant grass …

Effects Of Selective Logging And Roads On Instream Fine Sediments And Macroinvertebrate Assemblages In The Clackamas Basin, Oregon, Paula Elizabeth Hood

Dissertations and Theses

Logging and associated skid trails, haul routes, and roads can have significant impacts on the magnitude and timing of sediments in streams in forested watersheds. Loss of vegetation, soil compaction, use of heavy logging equipment, and alteration of natural hydrologic patterns within the watershed can increase landslide rates, create erosion, and generate fine sediments. Selective logging, also called thinning, is a logging practice that leaves some trees within sale units unharvested. The ecological impacts of thinning on stream ecosystems are not fully understood and need further study. My hypothesis was that macroinvertebrate assemblages would be different in streams in non-reference …

Rapid Response Tools And Datasets For Post-Fire Modeling: Linking Earth Observations And Process-Based Hydrological Models To Support Post-Fire Remediation, Mary Ellen Miller, Michael Billmire, William J. Elliot, K. A. Endsley, P. R. Robichaud

Michigan Tech Research Institute Publications

Preparation is key to utilizing Earth Observations and process-based models to support post-wildfire mitigation. Post-fire flooding and erosion can pose a serious threat to life, property and municipal water supplies. Increased runoff and sediment delivery due to the loss of surface cover and fire-induced changes in soil properties are of great concern. Remediation plans and treatments must be developed and implemented before the first major storms in order to be effective. One of the primary sources of information for making remediation decisions is a soil burn severity map derived from Earth Observation data (typically Landsat) that reflects fire induced changes …

Mapping Ancient Baldcypress Forests For Conservation At Black River, North Carolina, Jordan Nichole Burns

Graduate Theses and Dissertations

A few ancient baldcypress-bottomland hardwood forests survive across the southeastern United States in a mosaic of remnant old-growth stands left untouched by extensive logging during the early 20th century. Uncut stands in the Southeast that survived centuries of disturbance following European settlement tended to be too senescent and non-commercial to justify logging. Remnant ancient baldcypress forests at Black River, North Carolina, appear to contain the oldest living trees in eastern North America and The Nature Conservancy has protected several of these stands. However, the full extent of ancient bottomland forests along Black River is not known and many valuable tracts …
