Assessing Spatio-Temporal Patterns Of Forest Decline Across A Diverse Landscape In The Klamath Mountains Using A 28-Year Landsat Time-Series Analysis, Drew S. Bost Jan 2018

Assessing Spatio-Temporal Patterns Of Forest Decline Across A Diverse Landscape In The Klamath Mountains Using A 28-Year Landsat Time-Series Analysis, Drew S. Bost

Cal Poly Humboldt theses and projects

Rates of tree mortality in California and the Pacific Northwest have greatly increased in recent years, driven largely by pest and pathogen outbreaks as well as the effects of hotter, warmer droughts. While there have been a multitude of regional-scale assessments of mortality and forest decline, landscape-level studies are necessary to better identify forests that are most vulnerable to decline and to anticipate future changes. This need is particularly notable in the remote and little-studied mountains of northwest California, which are renowned for their diverse, heterogeneous vegetation types. A recent observation of elevated levels of Shasta red fir (Abies …


The Infrastructure-Extractives-Resource Governance Complex In The Pan-Amazon: Roll Backs And Contestations, Denise Bebbington, Ricardo Verdum, Cesar Gamboa, Anthony J. Bebbington Jan 2018

The Infrastructure-Extractives-Resource Governance Complex In The Pan-Amazon: Roll Backs And Contestations, Denise Bebbington, Ricardo Verdum, Cesar Gamboa, Anthony J. Bebbington

Geography

Large-scale access and energy infrastructure projects, together with expanding investments in natural resource extraction, pose significant challenges to biodiversity conservation, forest cover, and the defence of forest peoples' rights and livelihoods across the wider Amazon region. Following a period in which safeguards and forest dwellers' territorial rights were strengthened under more permissive political opportunity structures, the current period has been characterized by efforts to weaken these protections and to facilitate large-scale private investment in previously protected lands. We describe these investment-based threats to forests and rights, and the nature of regulatory rollbacks in the region. We then discuss some of …


Colonialism And Its Aftermaths In Vieques, Puerto Rico: How U.S. Hegemony Led To Contamination, A Superfund Site, And Local Mistrust, Kaya Mark Jan 2018

Colonialism And Its Aftermaths In Vieques, Puerto Rico: How U.S. Hegemony Led To Contamination, A Superfund Site, And Local Mistrust, Kaya Mark

Scripps Senior Theses

After sixty-two years of U.S. military testing, the small Puerto Rican island of Vieques and its residents continue to fight against ongoing environmental and social effects of U.S. hegemony. Starting with the arrival of the Spanish, then with U.S. occupation and use of Vieques as a military stopover, Viequense residents are used to U.S. governmental presence on their land. Despite the military’s removal from Vieques in 2003, many local residents have a fundamental lack of trust for the U.S. government. Because of this lack of trust and transparency with U.S. governmental actions in the post- World War II period, residents …

School of Natural Resources: Faculty Publications

Drought is a complex phenomenon manifested through interactions between biophysical and social factors. At the Wind River Indian Reservation (WRIR) in west-central Wyoming, water shortages have become increasingly common since the turn of the 21st century. Here we discuss the 2015 water year as an exemplar year, which was characterized by wetter-than-normal conditions across the reservation and, according to the U.S. Drought Monitor, remained drought-free throughout the year. Yet parts of the reservation experienced harmful water shortages, or “microdrought” conditions, during the growing season in 2015. In this assessment of the 2015 water year at the WRIR we: (1) describe …


Compression And Relaxation Of Fishing Effort In Response To Changes In Length Of Fishing Season For Red Snapper (Lutjanus Campechanus) In The Northern Gulf Of Mexico, Sean P. Powers, Kevin Anson Jan 2018

Compression And Relaxation Of Fishing Effort In Response To Changes In Length Of Fishing Season For Red Snapper (Lutjanus Campechanus) In The Northern Gulf Of Mexico, Sean P. Powers, Kevin Anson

University Faculty and Staff Publications

A standard method used by fisheries managers to decrease catch and effort is to shorten the length of a fishery; however, data on recreational angler response to this simple approach are surprisingly lacking. We assessed the effect of variable season length on daily fishing effort, measured by using numbers of boat launches per day, anglers per boat, and anglers per day from video observations, in the recreational sector of the federal fishery for red snapper (Lutjanus campechanus) in coastal Alabama. From 2012 through 2017, season length fluctuated from 3 to 40 d. Daily effort, measured by using mean number of …

Production And Economic Analyses Of Woody Biomass Utilization For Energy, John Edward Vance

Graduate Theses, Dissertations, and Problem Reports (ETD)

A mechanized harvest system combined with whole-tree chipper producing mixed hardwood chips was investigated on two harvesting sites in the central Appalachian region, USA. Production and machine rate data of the operations were collected through time-motion study, with chipping time elements categorized into feeding, chipping, and loading. Chipping cycles averaged 21.5 minutes to produce 23.54 green tons per truckload, providing an hourly rate of 65.82 green tons/PMH (41.1 dry tons) by the whole-tree chipper. Total cycle time including truck delivery averaged 183 minutes, giving an hourly rate of 7.7 green tons/PMH (4.8 dry tons/PMH). The hourly cost of the harvesting …


Agroforestry Standards For Regenerative Agriculture [Review], Craig R. Elevitch, D. Niki Mazaroli, Diane Ragone Jan 2018

Agroforestry Standards For Regenerative Agriculture [Review], Craig R. Elevitch, D. Niki Mazaroli, Diane Ragone

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

Agroforestry is increasingly being recognized as a holistic food production system that can have numerous significant environmental, economic, and social benefits. This growing recognition is paralleled in the USA by the budding interest in regenerative agriculture and motivation to certify regenerative practices. Current efforts to develop a regenerative agriculture certification offer an opportunity to consider agroforestry’s role in furthering regenerative goals. To understand this opportunity, we first examine how agroforestry practices can advance regenerative agriculture’s five core environmental concerns: soil fertility and health, water quality, biodiversity, ecosystem health, and carbon sequestration. Next, we review a subset of certification programs, standards, …

Relationship Between Corporate Social Responsibility, Environmental Management, And Profitability, Dr. Daisy Valentin

Walden Dissertations and Doctoral Studies

The U.S. hospitality industry's profitability has been shifting to environmental management and corporate social responsibility (CSR) practices. Hospitality industries accounted for 5% of the global market in 2015 and are expected to increase by 130% in 2035. Grounded in stakeholder theory, this correlation study examined the relationship between corporate sustainability officer (CSO) CSR, CSO environmental management, and hospitality business profitability. Secondary data were collected from 97 hotel websites of the Minneapolis-St. Paul, Minnesota area from 2014 to 2016. The multiple linear regression combinations of CSR and environmental management (EM) measured significantly related to the profitability index, F(3, 93) = 4.67, …


Strategies To Maintain Adequate Hotel Water Supplies, Deborah R. Popely Jan 2018

Strategies To Maintain Adequate Hotel Water Supplies, Deborah R. Popely

Walden Dissertations and Doctoral Studies

Hotel guests can use 2 to 3 times more water than community residents. Hotels are water-intensive businesses, and water scarcity presents a pressing problem for managers who rely on an uninterrupted supply of water to meet guests' needs and maintain profitability. Using the resource-based view (RBV) as a conceptual framework, the purpose of this qualitative multiple case study was to explore strategies that hotel managers used to successfully maintain adequate water supplies in the Spanish Canary Islands, an historically arid site and a tourism destination. Data were collected from semistructured interviews and hotel water usage reports. Yin's 5-step approach of …


Whose Lands? Which Public?: The Shape Of Public-Lands Law And Trump's National Monument Proclamations, Jedediah Britton-Purdy Jan 2018

Whose Lands? Which Public?: The Shape Of Public-Lands Law And Trump's National Monument Proclamations, Jedediah Britton-Purdy

Faculty Scholarship

President Trump issued a proclamation in December 2017 purporting to remove two million acres in southern Utah from national monument status, radically shrinking the Grand-Staircase Escalante National Monument and splitting the Bears Ears National Monument into two residual protected areas. Whether the President has the power to revise or revoke existing monuments under the Antiquities Act, which creates the national monument system, is a new question of law for a 112-year-old statute that has been used by Presidents from Theodore Roosevelt to Barack Obama to protect roughly fifteen million acres of federal land and hundreds of millions of marine acres. …

A Decade Of Governing The Blackfoot Community Conservation Area (Bcca): Community Involvement And Landscape Connectivity Through Public Private Partnerships, Alexander A. Barton Jan 2018

A Decade Of Governing The Blackfoot Community Conservation Area (Bcca): Community Involvement And Landscape Connectivity Through Public Private Partnerships, Alexander A. Barton

Graduate Student Theses, Dissertations, & Professional Papers

In recent decades, non-governmental organizations have acquired and established community forests and conservation areas in the U.S. However, there have been few empirical studies on their governance. This study focuses on the Blackfoot Community Conservation Area (BCCA) in the Blackfoot watershed of Montana, created in 2005. The BCCA is a 41,000 acre mosaic of private, state, and federal lands, including 5,600 acres known as the “Core” located near Ovando mountain and owned by the Blackfoot Challenge, a local watershed organization and leader in grassroots conservation. This research examined the definitions, activities and lessons learned over the past decade with regard …


40 Years On The International Flathead: An Assessment Of Transboundary River Governance, Jedd Sankar-Gorton Jan 2018

40 Years On The International Flathead: An Assessment Of Transboundary River Governance, Jedd Sankar-Gorton

Graduate Student Theses, Dissertations, & Professional Papers

Global population growth, climate change, and industrialization, are putting extreme pressures on worldwide freshwater supplies (Cosens 2010). Of the global freshwater supplies, transboundary water sources play a crucial role in sustaining populations. Over 40% of humans on Earth rely on a transboundary river or lake for access to water, and 90% of the world’s population lives in countries that share bodies of water with at least one other country (UN 2008). Taken together, the motivations for improving governance of transboundary water systems have never been stronger. To meet the challenges associated with transboundary water governance, researchers working at multiple scales …


Understanding The Food Water Nexus: Characterizing The Impact Of Climatological Anomalies On Agrosystems, Patrick M. Wurster Jr. Jan 2018

Understanding The Food Water Nexus: Characterizing The Impact Of Climatological Anomalies On Agrosystems, Patrick M. Wurster Jr.

Graduate Student Theses, Dissertations, & Professional Papers

Climate variability at global and regional scales is escalating with increased atmospheric carbon and is expected to magnify the intensity and duration of meteorological extremes, especially droughts. From the many environmental stresses that diminish crop production (e.g., soil salinity, frost, soil erosion) drought is one of the most prevalent. This study focuses on the sensitivity of three key crops produced in the northwestern United States to climatological anomalies, while controlling for attribution using anomalies in price. The study differs from similar studies in that we focus on variability in production which captures both yield (tonnes/ha) and cropping area (ha), as …

To Live And Fly In La: Using Bird Strike And Management Program Information To Improve Safety At Airports In The Los Angeles Basin, Todd J. Pitlik, Elizabeth Hermann, Eric Peralta, Brian E. Washburn

United States Department of Agriculture Wildlife Services: Staff Publications

Wildlife-aircraft collisions (wildlife strikes) pose a serious safety risk to aircraft. Wildlife strikes can be evaluated at different levels, include efforts to examine these problems at the national, regional, or state level, or for an individual airport. Similarly, wildlife strikes involving individual wildlife species or guilds can be examined at varying scales. Although wildlife strike analyses at the national, regional, or species/guild level are valuable, airport-specific analyses are essential for the effective implementation and evaluation of integrated wildlife damage management programs as these actions are conducted at the airport level. The species that present hazards to safe aircraft operations varies …


Chesapeake Bay Nutria Eradication Project: 2017 Update, Margaret Pepper, Kevin Sullivan, Robert Colona, Jonathan Mcknight Jan 2018

Chesapeake Bay Nutria Eradication Project: 2017 Update, Margaret Pepper, Kevin Sullivan, Robert Colona, Jonathan Mcknight

United States Department of Agriculture Wildlife Services: Staff Publications

Nutria, a semi-aquatic, South American rodent, was introduced to Maryland during the early 1940s. Originally brought to the area for fur farms, the market never established and animals were released or escaped. Nutria thrived, destroying coastal wetlands which resulted in negative environmental and economic impacts to the Chesapeake Bay region. To preserve and protect valuable wetland resources, the Chesapeake Bay Nutria Eradication Project (CBNEP) was established in 2002 through a partnership between the United States Fish and Wildlife Service, the United States Department of Agriculture’s Wildlife Services, Maryland Department of Natural Resources, and many state agencies and non-governmental organizations. Since …


Anticoagulant Rodenticide Residues In Game Animals In California, Stella C. Mcmillin, Robert H. Poppenga, Shannon C. Chandler, Deana L. Clifford Jan 2018

Anticoagulant Rodenticide Residues In Game Animals In California, Stella C. Mcmillin, Robert H. Poppenga, Shannon C. Chandler, Deana L. Clifford

United States Department of Agriculture Wildlife Services: Staff Publications

Anticoagulant rodenticides (ARs) are used to control rodents around homes, buildings, and in agriculture. They have been found widely in predatory and scavenging wildlife as a result of secondary exposure and less commonly in herbivores and omnivores from primary exposure. While predators and scavengers have been monitored for AR exposure, very little information is available about AR residues in edible muscle tissue of game animals. Game animals may be exposed to ARs through direct consumption of bait, ingestion of contaminated food or vegetation, or consumption of contaminated prey items. Carcasses of three species of game animals (black bear, wild pigs, …
