Effects Of Visitation On Reid State Park In Georgetown, Me, Meagan Hennessey

Atlas of Maine

Maine State Parks are in their 77th year, providing public access to a variety of scenic views, picnicking opportunities, freshwater and saltwater swimming, hiking, camping and a variety of other activities.1 These opportunities allow individuals to experience relatively undeveloped nature and can protect habitat for a variety of wildlife. On the other hand, concentrating large amounts of people in these natural areas can lead to degradation, and should be monitored closely and managed to the greatest ability.

In 2010, Reid State Park, in Georgetown, Maine was the most visited Maine State Park for day use, with 181,149 visitors.2 The Park …

Also represented are overlapping critical habitats for Least Terns and Piping Plovers, the former of which is endangered in the state of Maine. Note that Habitat representations are enlarged for …

Distribution Of Atlantic Forest Fragments In Relation To Probable Water Sources, Dominique Kone, Lydia Ball

Atlas of Maine

The Atlantic Forest of Brazil is highly fragmented and it is estimated that less than 7% of its original area remains (Umetsu et al. 2008). This high rate of fragmentation is primarily due to the conversion of forested areas into agricultural lands. This may hinder the dispersal of many species that inhabit this area because of an increase in edge effects, decrease in reproductive success, and higher limitation of resources. However, the inter-habitat matrix, or heterogeneous mosaic of varying habitats, may allow population dispersal and the creation of meta-populations within species. In particular, amphibians are extremely sensitive to habitat degradation …

Renewable Energy In Waterville: An Analysis Of Energy Load And Possible Biomass Facilities, Peter Smithy, Noah Teachey

Atlas of Maine

The goal of this research was to calculate the energy load of buildings in Waterville and to determine the feasibility of building a 5 Megawatt power plant at one of two sites. This would meet the heating requirements of the city through the piping of excess heat to the buildings. We determined the heating load by multiplying square footage with an estimate of energy load per square foot per year and the paths of the pipes were based on preexisting sewer pipes. Our preliminary analysis found that hypothetical power plant site 1 is more efficient in terms of piping distance …

Spatial Analysis Of Cardiovascular Disease Incidence And Potential Environmental Factors In The California Bay Area, Nick Papanastassiou, Sarah Holmes

Atlas of Maine

This project uses GIS to investigate proposed environmental factors that contribute to heart disease. This is based on several scientific articles (see references) that have hypothesized positive correlations between areas of increased air and noise pollution and dioxin emissions with heart disease incidence. We examined the Bay Area of California, which consists of nine counties. No significant correlation between our proposed factors and current heart disease incidence was found.

Factors Influencing Epa Sites Along The Hudson River, Cassie Raker

Atlas of Maine

The Hudson River is under constant environmental threat from the cities located along its shores. In this project I looked at EPA monitored sites (including sites covered by Superfund) along the Hudson River and their relationships with dam location and urban density. By examining the number of EPA sites in relation to these two environmental factors, we can see if some sites are under substantially more risk than others. My goal in this study was to determine the importance of the relationships between dam density, urban presence, and EPA monitored toxic sites using GIS.

Access To Green Space In Boston, Jillian Howell

Atlas of Maine

The purpose of this project was to use GIS and statistical analyses to explore the relationship between access to green space and race in Boston. Using census data, the city was divided by race and block groups. Block groups were categorized based on whether or not they were adjacent to green space. Findings concluded that races are not equally distributed across adjacent and non adjacent block groups, indicating unequal access to green space.

Modeling Habitat Suitability For Moose (Alces Alaces) In Maine, Lauren Hendricks

Atlas of Maine

The moose is very important to Maine for many reasons, including economic and aesthetic value. It can also be very dangerous to vehicles. To effectively manage moose populations, it is important to know where these animals might be located. Using a GIS and information about moose habitat preferences, I created a model of suitable habitat for moose in Maine. This model, based primarily on land cover, is supported by data on the actual distribution of moose in Maine.

Safety At Colby College: Location Of Emergency Call Boxes Marked By Blue Lights And Vulnerable Locations At Colby College, Emily Ten Eyck

Atlas of Maine

Emergency Call Boxes have been implemented into the security procedures at Colby College. The purpose of this project is to evaluate the visibility of the Emergency Call Boxes that can be located by an accompanying blue light. I found that 44.2% of my study area has visibility of a blue light, 6 buildings of 38 buildings at Colby college have less than 50% visibility in the area around the building, and 16.7% of paths and roads do not have visibility of a blue light.

Potential Sea Level Rise In Downeast Maine, Jillian Blouin

Atlas of Maine

According to the IPCC 2001 Climate Change Working Group, sea-level rise equivalent to all the ice on earth melting would be 69.31 meters. A large change in global temperatures would have dramatic impact on areas including Downeast Maine. This map shows the regions of Downeast Maine that would be flooded if sea levels rose 15, 25, or 35 meters. A 35 meter sea level rise would occur if 50% of polar ice melted.
