Effective monitoring of native bee populations requires accurate estimates of population size and relative abundance among habitats. Current bee survey methods, such as netting or pan trapping, may be adequate for a variety of study objectives but are limited by a failure to account for imperfect detection. Biases due to imperfect detection could result in inaccurate abundance estimates or erroneous insights about the response of bees to different environments. To gauge the potential biases of currently employed survey methods, we compared abundance estimates of bumblebees (Bombus spp.) derived from hierarchical distance sampling models (HDS) to bumblebee counts collected from fixed‐area …

Can The Vaquita Be Saved From Extinction?, Gerardo Rodríguez-Quiroz, Wenceslao Valenzuela-Quiñonez, Héctor A. González-Ocampo, Alfredo Ortega-Rubio
Human–Wildlife Interactions
The vaquita (Phocoena sinus) is considered the world’s most endangered marine mammal. It is the smallest member of the porpoise family endemic to the upper part of the Gulf of California. The current population is estimated at less than 30 individuals. The primary reasons for the species decline includes limited habitat and incidental mortalities associated with illegal gillnet fishing activities. Since 2008, the Mexican government has taken environmental and economic actions to protect the vaquita’s focusing in reducing by-catch deaths to zero. In 2015, a federal Agreement decreed by the Secretaría de Agricultura, Ganadería, Desarrollo Rural, Pesca y …

Not Waiting For Washington: Climate Policy Adoption In California And New York, Roger Karapin
Publications and Research
In the absence of strong U.S. national climate change policy, California and New York, among other states, adopted relatively comprehensive and ambitious policies to cut greenhouse gas emissions during the 2000s. They adopted these policies despite political-institutional and other structural barriers similar to those found nationally, which shows that political actors have significant scope for taking effective action even under structural constraints. This article explains the adoption of climate policies in these two leading states by using a windows of opportunity approach, which analyzes how the convergence of problem and political events produces policy windows and hence opportunities for advocacy …

Public lands owned by the Bureau of Land Management are increasingly being used for photovoltaic (PV) system development. Although numerous policies support PV deployment on public lands, those managed by the Bureau of Reclamation have not been considered for PV development. Hydro-electric embankment dams, both publicly and privately owned, may have the potential to be development sites for distributed PV systems. A technical feasibility report was conducted for a case study of a PV installation on Trinity Dam, Trinity County, CA, and found embankment dams could potentially be feasible development sites. A mounting analysis found that a concrete slab reinforced …

Natural Resource Access Rights And Wrongs: Nontimber Forest Products Gathering In Urban Environments, Susan Charnley, Rebecca J. Mclain, Melissa R. Poe
Institute for Sustainable Solutions Publications and Presentations
This article uses research about non-timber forest products (NTFP) gathering in Seattle, Washington, USA to examine how people gain access to natural resources in urban environments. Our analysis focuses on gathering in three spaces: parks, yards, and public rights of way. We present a framework for conceptualizing access, and highlight cognitive mechanisms of access associated with foragers’ internal moral judgments about harvesting. Key findings are: (1) internal moral calculations about whether it is right or wrong to harvest a particular NTFP in a particular place are an important but previously unacknowledged mechanism governing resource access; and (2) these calculations may …

Sustainability and Social Justice
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 …

Public Participation During Reactive, Crisis-Driven Drought Planning Versus Proactive, Preparedness Planning, C. Anna Ulaszewski
Walden Dissertations and Doctoral Studies
Droughts are occurring globally and should be recognized as a global issue and drought planning should use a proactive approach on the part of the world community. However, much drought planning, even in developed and highly developed countries, is reactive and programs are often poorly coordinated sometimes with unforeseen negative consequences for marginalized and disenfranchised populations. Literature pertaining to planning strategy for existing, drought crises is nominal and often contributes to patterns of reactiveness and resulting inequity. To gain a better understanding of crisis-driven planning and the participatory process, this gap was viewed through the lenses of institutional analysis and …

Determining Pathways And Connections Between Access To Water And High School Noncompletion Rates For Communities Along The U.S.–Mexico Border, Margie R. Vela, Sarah E. Lind, Paul H. Gutierrez
Journal of Sustainable Social Impact
Lack of access to potable water through a conveyance system impacts all aspects of modern life. Many colonias, communities in the Southwestern United States along the U.S.–Mexico border, continue to lack access to piped and treated water. This article discusses a model for the pathway from lack of access to water to lack of high school completion, including intermediary conditions impacting wellness, health, and quality of life for community members. A facilitated discussion with five environmental and public health experts who frequently work in the colonias of El Paso County, Texas (border communities that resemble the developing world), established …

Searching The Internet To Estimate Deer Population Trends In The U.S., California, And Connecticut, G. Webb
Faculty Research, Scholarly, and Creative Activity
Information for decision making may be publicly available, but costly to obtain. As an experiment in environmental scanning, the internet was searched on a daily basis over several years to collect information and provide analysis related to decisions on deer management. The process discovered that, contrary to common assumptions, the U.S. deer population has apparently been falling since about the year 2000 based on analysis of available state data that had not been aggregated. In some cases, state population estimates were created using standard procedures on available data. Results indicate that differences in survey methods appear to be relatively constant …

Environmental Injustice And Racial/Ethnic Heterogeneity In Houston, Texas, Michel G. Loustaunau Garcia
Open Access Theses & Dissertations
This Thesis seeks to contribute to distributive environmental justice (EJ) research by analyzing racial/ethnic and intra-ethnic disparities in potential health risks from exposure to hazardous air pollutants (HAPs) in Harris County, the most populous county in Texas. Previous EJ research in this urban area has not examined intra-ethnic heterogeneity in exposure to air pollutants or attempted to compare social disparities in exposure to air pollution caused by vehicular (mobile) and point (stationary) sources. The goal of this study is to determine how the EJ implications of cancer risks from inhalation exposure to HAPs from mobile and stationary sources differ across …

Human–Wildlife Interactions
Abstract – The Shoesole Management Team (Shoesole) and the Stewardship Alliance of Northeastern Elko (SANE) are place-based, landowner-organized, natural and human resource conservation initiatives. The Shoesole was organized in 2002 to take a more holistic approach to grazing management issues on two federal livestock grazing allotments. This effort provided the foundation for SANE, which was organized in 2012 by representatives of eight ranches in northeastern Nevada in response to the potential listing of the greater sage-grouse (Centrocercus urophasianus; sage-grouse). Shoesole and SANE came together voluntarily, as a rancher organized initiative, with a common goal of creating a better …

Since 1995, sage-grouse (Centrocercus spp.) conservation planning in the western United States has largely been based upon local working groups comprised of federal, state and local governments, environmental groups, landowners, interested citizens. In this article, we review the history and process of these local working groups in western Colorado. These groups are generally convened by one or more government agencies, operate on the general principle of consensus, and have little or no administrative or financial support. The local working groups were generally comprised of field biologist, rancher/landowners, members of local environmental groups and occasionally representatives from local governments. The …

Abstract: The Utah Watershed Restoration Initiative (WRI) is a partnership-based program, administered by the Utah Department of Natural Resources, which seeks to improve the functional capacity of high priority watersheds throughout the state. Since its inception in 2006, the WRI partnership has completed nearly 1,500 projects to restore and rehabilitate over 526,091 ha in Utah watersheds. The WRI program is unique to the west, in that it transcends jurisdictional boundaries, and local, state, and federal management authority to focus finite resources on completing high priority conservation projects. We surveyed selected WRI selected participants in 2015 to determine what factors they …

The greater sage-grouse (Centrocercus urophasianus) has been the subject of multiple status reviews under the Endangered Species Act (ESA). Wyoming accounts for approximately 38% of the range-wide population. Since 2000, 2 statewide and 8 local citizen working groups have been established in Wyoming to developed conservation plans and advise state policy. The first statewide plan for the conservation of sage-grouse was formally adopted in 2003. The statewide plan established local sage-grouse working groups charged with developing and facilitating implementation of local conservation plans. Those 8 plans were completed in 2007 and 2008, and updated in 2014. From 2005-2017, …

This capstone is a data-driven investigation into New York City's rat problem. By using publicly available government data to map rat activity in NYC, I identified several socio-economic variables that correlate with rat populations at the community district, borough, and city-scale. I used these findings (mainly that rat problems are linked to lower incomes) as the basis of an investigation, which includes interviews with residents, experts, and city officials. Prof. Bobby Corrigan, urban rodentologist and formerly with the NYC Department of Health criticizes the city's efforts for the first time on the record.

New York City has 520 miles of shoreline--that’s more than Miami and Los Angeles combined. These waterfronts are home to some of the city’s most polluted sites because major part of it is zoned for industrial use. Dozens of industrial plants in this area store toxic chemicals in flood zones: substances that are hazardous to our health, like Benzene, which is used in rocket fuel, toluene, a paint thinner, and lead a neurotoxin. In a flood, these chemicals can easily get caught up in moving waters and pollute entire neighborhoods.
That’s exactly what happened when Hurricane Sandy hit in 2012. …
