Evaluating Oyster Aquaculture’S Cost-Effectiveness As A Nitrogen Removal Best Management Practice – A Case Study Of The Delaware Inland Bays, Jefferson F. Flood

Journal of Ocean and Coastal Economics

Disease and overfishing have led to a dramatic decline in wild populations and subsequent harvests of the eastern oyster Crassostrea virginica over the past few decades in Delaware and other states along the Atlantic Coast. However, in addition to their value as food to consumers, oysters, whether wild populations or cultured stocks, can provide ecosystem services such as nutrient removal, which may result in localized water quality improvements. Consequently, recent policies in Delaware have sought to establish and grow an oyster aquaculture industry. However, a key challenge to achieving efficient levels of industry growth and water quality improvements is that …

Estimating Offsets For Avian Displacement Effects Of Anthropogenic Impacts, Jiill A. Shaffer, Charles R. Loesch, Deborah A. Buhl

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Biodiversity offsetting, or compensatory mitigation, is increasingly being used in temperate grassland ecosystems to compensate for unavoidable environmental damage from anthropogenic developments such as transportation infrastructure, urbanization, and energy development. Pursuit of energy independence in the United States will expand domestic energy production. Concurrent with this increased growth is increased disruption to wildlife habitats, including avian displacement from suitable breeding habitat. Recent studies at energy-extraction and energy-generation facilities have provided evidence for behavioral avoidance and thus reduced use of habitat by breeding waterfowl and grassland birds in the vicinity of energy infrastructure. To quantify and compensate for this loss in …

Enhancing Rural Economies Through Agroforestry, Gary Bentrup, Dean Current, Christopher Hartley, Marlen Eve, Tricia Kovacs, Kate Mcfarland, Eric Norland, David Smith, Susan Stein, Richard Straight

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Executive Summary

Accelerating the adoption of agroforestry will require a better understanding of the economic opportunities and financial benefits to society, says a recent assessment of United States agroforestry.1 Providing this understanding is critical for agroforestry to reach its full potential, whereby it enhances rural economies and provides ecological services that people need, such as clean drinking water. To assess emerging opportunities, the United States Department of Agriculture (USDA) convened more than 60 people in March 2018 to learn, network, and, above all, generate ideas for raising the economic profile and viability of agroforestry in the United States.

Resisting Industrial Food Systems On The Web: How Non-Profit Organizations Use Digital Technology For Sustainability Education, Aleksandr Segal

Dissertations, Theses, and Capstone Projects

This thesis examines the link between how community-based organizations use digital tools with the fundamentally resistance-based philosophy that these organizations have at the core of their mission. It aims to uncover how non-profit organizations (NPOs) that work in community development through food and agriculture use digital tools, and how their digital communication strategies relate to issues of resistance to neoliberalism and industrialization in the food and agriculture sectors.

Using a foundation of existing literature on food and agriculture, climate change and waste management, critical theory, and technology in pedagogy, this thesis will contextualize how non-profits resist neoliberal regimes of de-traditionalization …

Scientists, Uncertainty And Nature, An Analysis Of The Development, Implementation And Unintended Consequences Of The Northwest Forest Plan, Gilbert David Miller

Dissertations and Theses

The conflict in the Pacific Northwest between competing visions of how federal forests should be managed resulted in a political stalemate in the early 1990s. The Northwest Forest Plan (NWFP) was initiated to resolve the demands for maintaining ecosystem processes and biological diversity with the social and economic needs for timber harvest. The foundation for the plan rested with the development of ecosystem management. The intent of this research is to explore the events which led up to the adoption of the NWFP, how it was implemented by the US Forest Service and Bureau of Land Management and the subsequent …

Effects Of Land Use On Greenhouse Gas Flux In Playa Wetlands And Associated Watersheds In The High Plains, Usa, Dale W. Daniel, Loren M. Smith, Scott T. Mcmurry, Brian A. Tangen, Charles F. Dahl, Ned H. Euliss Jr., Ted Lagrange

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

In the High Plains, U.S., native prairie conversion to cropland agriculture has resulted in a loss of service delivery capabilities from most depressional wet-lands as a result of sedimentation. Restoring historic hydrological conditions to affected wetlands may rejuvenate some services, however, there may be tradeoffs due to emissions of CH4 and N2O. We evaluated the influence of two predominant conservation programs (Wetlands Reserve Program, WRP and Conservation Reserve Program, CRP) on gas emissions (CO2, CH4, N2O) from 42 playas and uplands in the High Plains of Nebraska. Because playa restoration through the WRP is most prevalent in the Rainwater Basin …

Whooping Crane Use Of Riverine Stopover Sites, David M. Baasch, Patrick D. Farrell, Shay Howlin, Aaron T. Pearse, Jason M. Farnsworth, Chadwin B. Smith

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Migratory birds like endangered whooping cranes (Grus americana) require suitable nocturnal roost sites during twice annual migrations. Whooping cranes primarily roost in shallow surface water wetlands, ponds, and rivers. All these features have been greatly impacted by human activities, which present threats to the continued recovery of the species. A portion of one such river, the central Platte River, has been identified as critical habitat for the survival of the endangered whooping crane. Management intervention is now underway to rehabilitate habitat form and function on the central Platte River to increase use and thereby contribute to the survival of whooping …

Modeling Effects Of Crop Production, Energy Development And Conservation-Grassland Loss On Avian Habitat, Jiill A. Shaffer, Cali L. Roth, David M. Mushet

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Birds are essential components of most ecosystems and provide many services valued by society. However, many populations have undergone striking declines as their habitats have been lost or degraded by human activities. Terrestrial grasslands are vital habitat for birds in the North American Prairie Pothole Region (PPR), but grassland conversion and fragmentation from agriculture and energy-production activities have destroyed or degraded millions of hectares. Conservation grasslands can provide alternate habitat. In the United States, the Conservation Reserve Program (CRP) is the largest program maintaining conservation grasslands on agricultural lands, but conservation grasslands in the PPR have declined by over 1 …

Diurnal Habitat Selection Of Migrating Whooping Crane In The Great Plains, David M. Baasch, Patrick D. Farrell, Aaron T. Pearse, David A. Brandt, Andrew J. Caven, Mary J. Harner, Greg D. Wright, Kristine L. Metzger

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Available stopover habitats with quality foraging opportunities are essential for migrating waterbirds, including Whooping Crane (Grus americana). Several studies have evaluated habitats used by Whooping Crane for roosting throughout its migration corridor; however, habitats associated with foraging and other diurnal activities have received less attention. We used data collected from 42 Whooping Crane individuals that included 2169 diurnal use locations within 395 stopover sites evaluated during spring 2013 to fall 2015 to assess diurnal habitat selection throughout the U.S. portion of the migration corridor. We found that Whooping Crane selected wetland land-cover types (i.e., open water, riverine, and semipermanent wetlands) …

Revisiting The Historic Distribution And Habitats Of The Whooping Crane, Jane E. Austin, Matthew A. Hayes, Jeb A. Barzen

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Understanding the historic range and habitats of an endangered species can assist in conservation and reintroduction efforts for that species. Individuals reintroduced into a species’ historic core range have a higher survival rate compared to individuals introduced near the periphery or outside the historic range (Falk and Olwell, 1992; Griffith et al., 1989). Individuals on the periphery of a species’ range tend to occupy less favorable habitats and have lower and more variable densities than those near the core of their range (Brown, 1984; Brown et al., 1995, 1996). Such conclusions, however, presume that historic habitats have not changed since …

Mortality In Aransas-Wood Buffalo Whooping Cranes: Timing, Location, And Causes, Aaron T. Pearse, David A. Brandt, Barry K. Hartup, Mark T. Bidwell

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

The Aransas-Wood Buffalo Population (AWBP) of Whooping Cranes (Grus americana) has experienced a population growth rate of approximately 4% for multiple decades (Butler et al., 2014a; Miller et al., 1974). Population growth for long-lived species of birds is generally highly sensitive to variation in adult mortality rates (Sæther and Bakke, 2000). A population model for endangered Red-crowned Cranes (Grus japonensis) in Japan conforms to this pattern, where growth rate is most sensitive to adult mortality (Masatomi et al., 2007). Earlier analyses observed that the AWBP growth rate increased in the mid-1950s and that this increase was likely caused by reduced …
