Models suggest that average temperatures in the central Rocky Mountains will increase by >3°C over the next century, while precipitation may remain within late Holocene boundaries. This study investigates the potential hydrologic effects of such warming when combined with the full range of precipitation variability experienced over the past millennium. Using the upper Yellowstone drainage as a test case, a water balance model is constructed to estimate river discharge from precipitation and temperature inputs (r = 0.85 versus observed).
This 2003 study uses a survey method to gauge visitor preferences for specific physical, social, and managerial attributes of various beach areas along the North Carolina coast. Information obtained from this research is useful to on-site beach managers to obtain an understanding of varying user preferences and how to best meet the needs of their recreational user population.
A national survey of Conservation Reserve Program (CRP) contractees was completed to obtain information about environmental and social effects of the program on participants, farms, and communities. Of interest were observations concerning wildlife, attitudes about long-term management of program lands, and effectiveness of U.S. Department of Agriculture (USDA) assistance in relation to these issues. Surveys were delivered to 2,189 CRP participants with a resultant response rate of 64.5%. Retire
Natural resource management approaches are increasingly criticized for a tendency to neglect power relations and conflicts of interests, and negotiation approaches have been proposed to overcome these shortcomings.
The methods of cost-benefit analysis and predictive modeling were used by the Coral Reef Rehabilitation and Management Project (COREMAP) to determine and quantify the threats causing depletion of coral reefs in Indonesia. The results indicated that immediate actions need to be taken by the government to stop the depletion.
Risk-based planning can be used to assess reservoir operations under climate change, and this case study presents a flexible method for conducting risk assessment and identifying strategies for managing the operations system. The method allows managers to select appropriate risk metrics and periods of time relevant to their needs. This case study examines the method as applied to California's Central Valley Project and State Water Project systems.
The increasing use of off-highway vehicles (OHV) in the northeastern United States suggests the need for more effective recreation management strategies in public forest areas. This study analyzes the differences in attitudes toward intentions to engage in certain behaviors by off-highway vehicles (OVH) through testing relationships between attitude and behavior. The study employed the Theory of Planned Behavior (TPB)(Ajzen 1991) to examine the attitudes and perceptions of OVH operators, and the findings reflect a weak yet positive preference for specific management actions with the overall prefernce for behavior-specific, indirect management actions.
This study explored many existing research projects and grey literature available worldwide analyzing coastal fisheries and the well-being of the communities around them.

Wastewaters from oil and gas development pose largely unknown risks to environmental resources.
This research project grows out of a belief that, in order for citizens to care about the status of forested areas in the United States, people need to value the range of resources trees provide society.
Conducting a survey to identify fishermen's behaviors and practices.
This study uses social network analysis and interviewing to determine the most influential or key individuals within the fishing community of North Carolina. The South Atlantic Fishery Management Council sponsored research done on charter, commercial, and recreational king mackerel fishermen in efforts to improve communication between fishermen and the council.
The vulnerability framework of the Research and Assessment Systems for Sustainability Program explicitly recognizes the coupled human–environment system and accounts for interactions in the coupling affecting the system's responses to hazards and its vulnerability. This paper illustrates the usefulness of the vulnerability framework through three case studies: the tropical southern Yucatán, the arid Yaqui Valley of northwest Mexico, and the pan-Arctic. Together, these examples illustrate the role of external forces in reshaping the systems in question and their vulnerability to environmental hazards, as well as the different capacities of stakeholders, based on their access to social and biophysical capital, to respond to the changes and hazards.
This study uses focus groups and case study research involving stakeholder representatives to revise the four zones and management system within the Folkestone Park and Marine Reserve on the west coast of Barbados.
The Landsat program has been collecting and archiving moderate resolution earth imagery since 1972. The number of Landsat users and uses has increased exponentially since the enactment of a free and open data policy in 2008, which made data available free of charge to all users. Benefits from the information Landsat data provides vary from improving environmental quality to protecting public health and safety and informing decision makers such as consumers and producers, government officials and the public at large. Although some studies have been conducted, little is known about the total benefit provided by open access Landsat imagery. This report contains a set of case studies focused on the uses and benefits of Landsat imagery. The purpose of these is to shed more light on the benefits accrued from Landsat imagery and to gain a better understanding of the program’s value.
This project used survey methods to identify long-term recovery needs of Louisiana communities impacted by Hurricanes Katrina and Rita. It provides an example of how an in person survey can be conducted in a public meeting setting. This project allowed organizers to gather extensive input from Louisiana citizens to inform the recovery planning efforts of local, state, and federal entities.
Hydrocarbon production in the United States using horizontal drilling and hydraulic fracturing has created substantial opportunities to research the potential effects on groundwater from acquiring these unconventional oil and gas reservoirs. However, many data gaps limit the ability to fully assess the degree of impact
This study uses survey research, demographic analysis, and secondary data analysis to determine the effectiveness of management practices and regulations in two reserves in northwestern Sicily. Results of the research revealed that better management practices would be needed for more effective reserves.
This case study takes a closer look at Moose-vehicle collisions in the state of Vermont, where one third of all reported moose-vehicle collisions result in motorist injury or fatality.
This report summarizes the results of the Phase I Community Awareness Review and Development (CARD) project sponsored by the Lake Superior Binational Program. The intent of the project was to survey knowledge and awareness of issues relevant to the Lake Superior Binational Program (especially the Lakewide Management Plan or LaMP) in order to foster improved decision-making within the Lake Superior basin. Most of those surveyed cited economic concerns as most pressing and environmental concerns as least pressing.
Place-based inquiry is a promising vehicle for meaningful participation among stakeholders, and the heritage area of Common Ground Land in Kenora, Ontario, provides an opportunity to examine the relationship between place-based inquiry and meaningful participation. Semistructured interviews and modified focus groups were used for participation mechanisms, and the results have revealed themes related to connections, perspectives, and visions for the Common Ground Land.
This study uses rapid socioeconomic evaluation, content analysis, observation, and secondary data to determine the possibility of establishing a marine conservation district (MCD) south of St. John Island in the U.S. Virgin Islands. This preliminary research gained many recommendations from commercial fishermen and recreational dive organizations concerning the establishment of an MCD.
This case study describes the involvement of Ecotrust, a conservation organization based in Portland, Oregon, in bringing fishermen's expertise into the process of marine protection area (MPA) designation along the California coast.
This case study presents an innovative approach to involving stakeholders in restoration of coastal resources. State resource managers conducted focus groups and broader public meetings to gain insight on the social and economic benefits that should be included in a net benefits analysis of restoring the Deschutes Estuary in downtown Olympia, Washington. The stakeholder input was then delivered to professional economists who conducted the net benefits analysis (NBA). This project demonstrates how social science methods such as focus groups can be used to provide the foundation for socioeconomic analyses of coastal resources.
This study uses survey research and observation conducted by the Olympic Coast National Marine Sanctuary to create educational materials informing stakeholders and shipping companies of the risks to natural and cultural resources from oil spills. These methods were successful in obtaining a 90 to 95 percent compliance rate.
Waterfowl habitat is a biological resource which is neither bought nor sold in the traditional market sense. Nebraska, which is situated near the center of the North American Central Flyway, contains unique wetland habitat. Recognizing this, resource managers working in Nebraska promote regulatory protection of such areas.
The project began in January 2006 and in ongoing. To date, scientists have identified several toxins and chemical properties in the particular algae.

There is an increasingly competitive environment for funding community programs, and this case study looks at how Extension programs are evaluated across four states to establish a set of standards for measuring common elements among programs with regard to impact, participation, and cross-program comparisons.
The researchers assessed black bear harvest trends that involve bait. The study took place from 1992 to 2010 in Alaska and examined increases in the use of this harvesting method in three different spatial areas and in comparison with changes in use of other harvesting methods. The study is used to address the ethics of harvesting black bears using bait, and not incorrectly characterize the issue as addressing black bear conservation or population management.
This study uses ethnography, historical research, and demographic analysis to evaluate the effectiveness of different management practices for marine fisheries in Fiji. The research found many results concerning community-based marine protected area management.
Public engagement is a key role in developing and implementing laws and policies, and managers continually seek ways to increase involvement from stakeholders. This case study examines a Wyoming Game and Fish Department plan for managing its portion of the Yellowstone grizzly bear population, and the perception of the role of each stakeholder by the other stakeholders affected the plan.
Population growth and a changing climate will tax the future reliability of the Colorado River water supply. Using a heuristic model, we assess the annual risk to the Colorado River water supply for years 2008–2057.
Southern California has many rocky intertidal marine reserves; most of these reserves have been in existence for over 30 years. Although removal of organisms is prohibited in such reserve areas, researchers have shown that a lack of signage and enforcement has led to very low levels of compliance. The result is a deterioration of the rocky intertidal zone. To prevent further deterioration of the rocky intertidal ecosystems, enforcement of the regulations prohibiting organism removal would be necessary. Such implementation would have associated costs.
