Assessing Lakesmart: The Development And Effectiveness Of A Lake Protection Program, Alexa A. E. Junker

Honors Theses

Maine’s nearly 6,000 lakes are a vital resource for the state, generating $6 billion in annual economic activity and sustaining 52,000 jobs. Over the course of the last several decades, this resource has increasingly been threatened by development and related problems, especially nutrient runoff. LakeSmart is a lake protection program designed to stem the flow of nutrient runoff by promoting and rewarding the use lake-friendly landscaping practices.

For this project, I traced the history of LakeSmart from its roots in the Maine Department of Environmental Protection and, through stakeholder interviews and surveys, chronicled its development into the flagship program of …

All’S Whale That Ends Whale: How Correctly Identifying Antarctic-Feeding Grounds Of Oceania Humpbacks Could Save An Endangered Population, Davey Holmes

Pomona Senior Theses

Although major whaling practices have ceased, increasing human involvement and influence in the world’s marine ecosystems continue to adversely effect global whale populations. It is a major concern throughout Antarctic waters, where endangered Oceania Humpback Whales (Megaptera novarangliae) annually feed. This study analyzes the extent to which a proposed marine protected area within the Ross Sea may indirectly harm the last remaining endangered population of Humpbacks. Using current satellite tracks of southern Humpback migrations, this model maps the effects of displaced Toothfish fisheries, and suggests further conservations efforts, based on New Zealand’s Precautionary Approach, to protect these vulnerable whales.

"One Narrow Thread Of Green": The Vision Of May Theilgaard Watts, The Creation Of The Illinois Prairie Path, And A Community's Crusade For Open Space In Chicago's Suburbs, Anne M. Keller

Antioch University Dissertations & Theses

Women's environmental activism prior to the early 1960s in America focused on women's roles as municipal housekeepers or emphasized wilderness conservation. I offer in this dissertation the story of the Illinois Prairie Path, the country's first rails-to-trails conversion to apply for National Recreation Trail status, and the innovative women who fought for nature preservation in a suburban setting rather than in a wilderness area. Led by renowned writer and naturalist, May Theilgaard Watts, these women built support for the public footpath project by fostering an ecological awareness throughout their region. I place them in the tradition of Chicago female reformers …

Recommendations For Conservation Easement Reform, Amy Murphy

Environmental Studies Senior Seminar Projects

Virginia has a well-established easement program which offers landowners a state income tax credit in return for donating land rights such as development and subdivision rights. Currently, there are inefficiencies with easements which could be lessened with reform (Owley 2011, Rissman 2011). This paper proposes that Virginia establish statewide conservation priorities and switches from a flat rate credit for easement donations to a tiered system which provides greater incentives for easements on land with high conservation value (McLaughlin and Pidot 2013). Additionally, this paper proposes that Virginia require adaptive language in easement terms and standardizes monitoring procedures.

Updated Marine Mammal Distribution And Abundance Estimates In British Columbia, Benjamin D. Best, Caroline H. Fox, Rob Williams, Patrick H. Halpin, Paul C. Paquet

Population Distribution and Habitat Collection

Information relating to the distribution and abundance of species is critical for effective conservation and management. For many species, including cetacean species of conservation concern, abundance estimates are lacking, out of date and/or highly uncertain. Systematic, line-transect marine mammal surveys were conducted in British Columbia’s (BC) coastal waters over multiple years and seasons (summer 2004, 2005, 2008, and spring/autumn 2007). In total, 10,057km of transects were surveyed in an 83,547km2 study area. Abundance estimates were calculated using two different methods: Conventional Distance Sampling (CDS) and Density Surface Modelling (DSM). CDS generates a single density estimate for each stratum, whereas DSM …

A Gis Assessment Of Ecoregion Representation In Chile's Existing And Proposed Integrated Network Of Protected Areas, Jessica Schutz

Graduate Student Theses, Dissertations, & Professional Papers

Chile's state designated protected areas are reported to show representation bias and to be unable to meet conservation goals. Private protected areas are considered an important tool to resolve these issues, which has led to support for increasing the role of private protected areas in Chile and creating an integrated public-private protected area network. But the validity of the capacity of private protected areas to fix Chile's state protected area network bias, and the advantage of creating an integrated protected area network, have not been assessed. This study uses the most recent data on Chile's state, private, and international protected …

The Role Of Hybridization And The United States Fish And Wildlife Service Biologists’ Discretion In The Implementation Of The Endangered Species Act, Jennifer F. Lind-Riehl

Dissertations, Master's Theses and Master's Reports - Open

The Endangered Species Act (ESA) requires that the “best available scientific and commercial data” be used to enable the protection of critically imperiled species from extinction and preserve biodiversity. However, the ESA does not provide specific guidance on how to apply this mandate. In addition, the interpretation of scientific data can be uncertain and controversial, particularly regarding species delineation and hybridization issues. US Fish and Wildlife Service (FWS) field biologists must decide what the best science is and how to interpret and apply it in their recommendations. As a result, FWS field biologists often have considerable discretion when it comes …

Indigenous Knowledge And Science Unite To Reveal Spatial And Temporal Dimensions Of Distributional Shift In Wildlife Of Conservation Concern, Christina N. Service, Megan S. Adams, Kyle A. Artelle, Paul C. Paquet, Laura V. Grant, Chris T. Darimont

Population Distribution and Habitat Collection

Range shifts among wildlife can occur rapidly and impose cascading ecological, economic, and cultural consequences. However, occurrence data used to define distributional limits derived from scientific approaches are often outdated for wide ranging and elusive species, especially in remote environments. Accordingly, our aim was to amalgamate indigenous and western scientific evidence of grizzly bear (Ursus arctos horribilis) records and detail a potential range shift on the central coast of British Columbia, Canada. In addition, we test the hypothesis that data from each method yield similar results, as well as illustrate the complementary nature of this coupled approach. Combining information from …

Photo-Identification Methods Reveal Seasonal And Long-Term Site-Fidelity Of Risso’S Dolphins (Grampus Griseus) In Shallow Waters (Cardigan Bay, Wales), Marijke N. De Boer, Josephine Clark, Mardik F. Leopold, Mark P. Simmonds, Peter J.H. Reijnders

Ecology Collection

A photo-identification study on Risso’s dolphins was carried out off Bardsey Island in Wales (July to September, 1997-2007). Their local abundance was estimated using two different analytical techniques: 1) mark-recapture of well-marked dolphins using a “closed-population” model; and 2) a census technique based on the total number of iden-tified individual dolphins sighted over the study period. The mark-recapture estimates of 121 (left sides; 64 - 178, 95% CI; CV 0.24) and 145 dolphins (right sides; 78 - 213, 95% CI; CV 0.24) closely matched the census technique estimates (population size of 90 - 151). It was found that the dolphins …

Conservation Easement Policies Across New England, Virginia A. Keesler

Honors Theses

This thesis examines conservation easement policies across the New England states. Conservation easements are legal agreements through which landowners donate or sell some or all of their properties' development rights to conservation entities, typically government entities or land trusts. I specifically ask: How do conservation easement policies compare across the New England states? How can conservation easement policies be reformed to enhance the use of easements as a conservation tool? Although easements allow conservation entities to conserve more land for less money, the ecological and social implications of the increased use of easements have been debated.

I evaluate data availability, …

Cartografía, Corredores Y Cooperación: La Búsqueda De Soluciones Transfronterizas En Las Fronteras Amazónicas, David S. Salisbury, Diego B. Leal, Andrea B. Chávaz Michaelsen, Bertha Balbín Ordaya, A. William Flores De Melo, Pedro Tipula Tipula, Maria Luiza Pinedo Ochoa

Geography and the Environment Faculty Publications

Implementation of conservation and development in the Amazon borderlands requires effective transboundary coordination. Updated, readily understandable, and transboundary cartography becomes increasingly essential in Southwestern Amazonia as residents and decision makers attempt to mitigate the socio-environmental challenges and impacts in the borderlands. The lack of updated borderland cartography complicates the planning of development, integration, and conservation projects at a variety of different scales. The Transboundary Geographic Group of Southwestern Amazonia (GTASO) has created a network to continuously exchange geographic information, resulting in a June 2013 workshop and the creation of five transboundary thematic maps of the Amazon regions of Ucayali and …

The Elwha River Restoration: Landscape Change, Salmon, And Sense Of Place, Kelseyanne Johnson

All Master's Theses

Removal of the Elwha River dams to restore the ecosystem and salmon fisheries is the largest project of its kind in the history of the United States. Spanning decades and affecting generations, this project has changed and will continue to change the landscape. This research examined the influence of the anticipated return of salmon on 18 key stakeholders' sense of place of the Elwha River. For almost all stakeholders, changes to the Elwha landscape are welcomed as they expect that salmon will restore the ecosystem to its natural state. Narrative data revealed dominant themes in participants' sense of place expressed …

The Fine-Scale Habitat Use Of Risso’S Dolphins Off Bardsey Island, Cardigan Bay (Uk), Marijke N. De Boer, Sonja Eisfeld, Mark P. Simmonds

Ecology Collection

The main objectives of this study were (1) to estimate the population size of Risso’s dolphins off Bardsey Island using mark-recapture techniques (De Boer et al., 2013); and (2) to study habitat-use in relation to fine-scale oceanographic features. This work provides preliminary information on the habitat-use of Risso’s dolphins and will benefit future studies, along with the development of effective conservation measures for this species throughout the region.

Coca And Conservation: Cultivation, Eradication, And Trafficking In The Amazon Borderlands, David S. Salisbury, C. Fagan

Geography and the Environment Faculty Publications

The cultivation and traffic of coca, Erythrolxylum coca, and coca derivatives remain understudied threats to the conservation of the Amazon rainforest. Currently the crop is transforming land use and livelihoods in the ecologically and culturally rich borderlands of Amazonian Peru. The isolated nature of this region characterized by indigenous populations (both settled and uncontacted), conservation units, resource concessions, and a lack of state presence provides fertile ground for the boom and bust cycle of coca production and facilitates the international transport of the product to neighboring Brazil. This paper explores the social and environmental impacts of coca production, eradication, and …

A Species-Based Approach To Transboundary Marine Conservation In The Caribbean Region, Carolyn Doherty

Geography and the Environment Capstone Projects

The basic theory of peace parks is applied to transboundary marine environments in this paper. Emphasizing connections across different scales, the ultimate goal of this paper is to resolve a specific ecological conflict: international conservation of migratory marine species in the Caribbean region. Migratory marine species like the green turtle (Chelonia mydas) create a unique dilemma for conservationists. Migratory species require diverse eco-regions for different stages of essential life processes. In the Caribbean region, these life processes occur regardless of political and economic boundaries, creating a predicament for marine conservation. Linking marine turtle harvest and conservation laws of the nations …

Extractive Reserves, David S. Salisbury

Geography and the Environment Faculty Publications

Extractive reserves are territories dedicated to environmental protection and the sustainable use of nature resources by traditional populations. Reserves follow a traditional land tenure model based on individual family and communal property rights to common areas, such as forest trails used to extract or harvest nontimber forest products. Although the extractive reserve concept originates in the tropical forests of the Brazilian Amazon, reserves have also been created in aquatic, floodplain, and savanna landscapes throughout Brazil. There are now 50 extractive reserves covering more than 10 million hectares, an area larger than Portugal, and more continue to be created. Despite their …

Participatory Planning For A Promised Land: Citizen-Led, Comprehensive Land Use Planning In New York’S Adirondack Park, Ann Hope Ruzow Holland

Antioch University Dissertations & Theses

New York’s Adirondack Park is internationally recognized for its biological diversity. Greater in size than Yellowstone, Everglades, Glacier, and Grand Canyon National Park combined, the Adirondacks are the largest protected area within the Northern Appalachian/Acadian Eco-Region and within the contiguous United States. Ecologists, residents of the Park, and others are concerned about rapid land use change occurring within the borders of the Park. Almost half of the six million acres encompassed by the Park boundary is privately-owned, where 80% of land use decisions fall within the jurisdiction of local governments. The comprehensive planning process of one such local government, the …

Human–Wildlife Conflict And Gender In Protected Area Borderlands: A Case Study Of Costs, Perceptions, And Vulnerabilities From Uttarakhand (Uttaranchal), India, Monica V. Ogra

Environmental Studies Faculty Publications

Human–wildlife conflict (HWC) is a growing problem for communities located at the borders of protected areas. Such conflicts commonly take place as crop-raiding events and as attack by wild animals, among other forms. This paper uses a feminist political ecology approach to examine these two problems in an agricultural village located at the border of Rajaji National Park in Uttarakhand (formerly Uttaranchal), India. Specifically, it investigates the following three questions: What are the “visible” and “hidden” costs of such conflict with wildlife? To what extent are these costs differentially borne by men and women? How do villagers perceive any such …

Moving Beyond Conflict: Private Stewardship And Conservation Partnerships, Lynn Scarlett

Center for Applied Economics

Aldo Leopold, one of the nation’s greatest leaders in the early conservation movement, had a vision of a nation of citizen stewards. He eloquently imagined that each of us in our own backyards and communities would serve as stewards of our environment. Environmental progress, he opined, ultimately resides in the actions taken by each and every one of us.

Africa's Conservation For Development, Norman Miller, Rodger Yeager

Dartmouth Scholarship

Africa's modern dilemma is a "floor of life" issue. Resource loss, environmental degredation, and overpopulation have reduced many people to the lowest subsistence levels in living memory. By all accounts a biologically diverse wonderland, Africa is quite literally the last place on earth for many plant and animal species. Yet the basis of human and nonhuman survival has become threatened in many areas because of soil and water depletion, deforestation, and desertification. Human mistakes are invariably cited as among the basic causes of these tragedies.

Journey In A Forgotten Land - Part 1: Food And Drought In Ethiopian/Kenyan Border Lands, Norman Miller

Dartmouth Scholarship

The herding peoples who live in the border areas of Kenya and Ethiopia share a common complaint. They believe themselves to be a forgotten people, unknown and unwanted in the capitals of Addis Ababa and Nairobi. This is not entirely true, but the remote, inhospitable nature of their land supports the belief that they are indeed untouched by the outside world. The majority of the people on both sides of the border are Boran, or their near cousins the Gabbra. They are traditionally pastoralists who move with their cattle, camels, sheep, and goats over vast areas of this dry land. …
