Why Do They Do That? Understanding Factors Influencing Visitor Spatial Behavior In Parks And Protected Areas, Abigail M. Sisneros-Kidd

All Graduate Theses and Dissertations

Visitors to parks and protected areas within the United States and worldwide often visit these areas with a particular destination in mind, such as seeing Old Faithful erupt in Yellowstone National Park or standing on the rim of the Grand Canyon in Grand Canyon National Park. These visitor use destinations, and the pathways leading to them, such as trails and roadways, see high levels of use, and as a result, impacts to soil, vegetation, air, water, soundscapes, and night skies that result from this use. The field of recreation ecology studies these impacts to park and protected area resources resulting ...

Assessment Of Floodplain Condition Across Puget Sound: An Emerging Tool For Tracking Investments And Communicating Status, Jennifer Burke, Colin Hume, Ilon Logan, Scott Mckinney Apr 2018

Assessment Of Floodplain Condition Across Puget Sound: An Emerging Tool For Tracking Investments And Communicating Status, Jennifer Burke, Colin Hume, Ilon Logan, Scott Mckinney

Salish Sea Ecosystem Conference

Floodplains are some of the most economically and ecologically vital lands of Puget Sound but also some of the most impaired as well. Investments at the local and regional level aim to improve aquatic and terrestrial habitat, reduce flood risk, and protect economically important lands. However, the condition and status of Puget Sound floodplains is poorly quantified in a consistent manner across the 17 major watersheds, hindering strategic investments and planning. The Puget Sound Partnership and Washington Department of Ecology are developing an assessment of floodplain condition and status for a Sound-wide watershed-scale floodplain monitoring effort using spatial data and ...

Nitrogen Inventory In The Nooksack-Fraser Transboundary Watershed, Jiajia Lin, Jana Compton, Jill Baron, Chris Clark, Donna Schwede, Shabtai Bittman, David Hooper, Barb Carey, Peter Homann, Hanna Winter, Peter Kiffney, Nichole Embertson, Heather Mackay, Robert Black, Gary Bahr

Salish Sea Ecosystem Conference

The Nooksack-Fraser transboundary area (2639 km2) is home to communities with a strong base in farming, fisheries and outdoor recreation. Water quality issues impact parts of this area, where sewage effluent and animal waste are potential sources of both fecal coliform bacteria (FCB) and nitrogen (N) in the environment. Excessive nitrogen loading can lead to eutrophication in coastal areas, and nitrate contamination of groundwater. The Nooksack-Fraser Transboundary Nitrogen (NFT-N) project was developed to determine the sources and fates of N in the watershed using data on energy use, transportation, fertilization, wastewater treatment plants, livestock operations, wildlife and more. This project ...


Noaa Rockfish Recovery Management And Research In The Salish Sea, Washington, James Selleck, Dan Tonnes Apr 2018

Noaa Rockfish Recovery Management And Research In The Salish Sea, Washington, James Selleck, Dan Tonnes

Salish Sea Ecosystem Conference

Rockfish are a long-lived species group that provide an important function for the food web dynamics in the Salish Sea, as both a mid-level trophic predator and important prey source, and they hold cultural significance to the region. Rockfish are comprised of over 25 different species locally, and over 60 species from California to Alaska. Many species experienced declines since the 1980’s, and two species are listed in the Salish Sea under ESA as threatened (yelloweye) or endangered (Bocaccio). Different species occupy a range of habitat types, from deep-water rock piles and hard bottom substrate, to nearshore kelp forests ...


A Framework For Incorporating The Toxicity Of Pesticide Mixtures Into Ecological Risk Assessments, Cathy Laetz, David H. Baldwin, Tony Hawkes, Scott A. Hecht, Nathaniel L. Scholz Apr 2018

A Framework For Incorporating The Toxicity Of Pesticide Mixtures Into Ecological Risk Assessments, Cathy Laetz, David H. Baldwin, Tony Hawkes, Scott A. Hecht, Nathaniel L. Scholz

Salish Sea Ecosystem Conference

Pesticides are widely used throughout the Puget Sound region and are frequently detected as complex mixtures in aquatic habitats. As a result, pesticide mixture toxicity is an important component of risk assessments performed within the Salish Sea region. Here we describe a process for assessing toxicity of three categories of pesticide mixtures; formulated products (one product containing multiple active ingredients), tank mixes (multiple pesticides applied simultaneously), and environmental mixtures (resulting from unrelated pesticide use over the landscape). Mixtures were assumed to be either dose-additive or response-additive, depending on the modes of action of the individual pesticide components. Toxicity estimates utilized ...


Determinants Of Household Water Use In The City Of Kalamazoo, Michigan: The Role Of Climate And Socioeconomic Factors, Danielle Molenaar Apr 2018

Determinants Of Household Water Use In The City Of Kalamazoo, Michigan: The Role Of Climate And Socioeconomic Factors, Danielle Molenaar

Master's Theses

Located in the Great Lakes Watershed, the City of Kalamazoo can be considered “water rich”. Therefore, the area has been absent from water use studies. Water use studies are beneficial in all locations; as they can aid city planners, water resource managers, and utility companies. This study examines how household monthly water use in the City of Kalamazoo is impacted by both climate and socioeconomic variables over the period 2006-2016. Household level data were aggregated into census tracts to obtain monthly tract averages for the eleven-year period. Ordinary least squares regression (OLS) was used to determine which variables impact the ...

Managing Birds And Controlling Aircraft In The Kennedy Airport–Jamaica Bay Wildlife Refuge Complex: The Need For Hard Data And Soft Opinions, John Tanacredi Ph.D., Kevin Brown, R. Michael Erwin, Milo E. Richmond, P A. Buckley, Dave Avrin

Dr. John T. Tanacredi

During the 1980s, the exponential growth of laughing gull (Larus atricilla) colonies, from 15 to about 7600 nests in 1990, in the Jamaica Bay Wildlife Refuge and a correlated increase in the bird-strike rate at nearby John F. Kennedy International Airport (New York City) led to a controversy between wildlife and airport managers over the elimination of the colonies. In this paper, we review data to evaluate if: (1) the colonies have increased the level of risk to the flying public; (2) on-colony population control would reduce the presence of gulls, and subsequently bird strikes, at the airport; and (3 ...

Dr. John T. Tanacredi

Floyd Bennett Field (FBF), 579 ha in extent, is a division of Gateway National Recreation Area. It is the site of a former airfield, constructed by filling salt marshes with dredged materials. Except for the portion known locally as the “North Forty,” all sections of FBF have been cut over to maintain low vegetation. A grassland management plan (GRAMP) for 165 ha was initiated in 1986, to maintain habitats for open-country birds. Over the next few years, encroaching woody vegetation was removed manually and mechanically from the management area. Since then, it has been maintained as a grassland and receives ...

Searching For A Robust Operation Of Lake Mead, Elliot Alexander Jan 2018

Searching For A Robust Operation Of Lake Mead, Elliot Alexander

Civil Engineering Graduate Theses & Dissertations

The Colorado River spans seven US states and Mexico and is an important cultural, economic, and natural resource for 35 - 40 million people. Its complex operating policy is based on the “Law of the River,” which has evolved since the Colorado River Compact in 1922. Operational guidelines were negotiated in 2007 to address shortage reductions and coordinated operations of Lakes Powell and Mead. These interim guidelines – in effect until 2026 - were ultimately agreed on after manually exploring hundreds of alternatives. The Colorado River Basin’s projected water delivery reliability has continued to degrade since 2007, primarily due to a persistent ...

The Spatial Context Of “Winning” In Mpa Network Design: Location Matters, Andrew S. Kough, Claire B. Paris, Mark J. Butler Iv

Biological Sciences Faculty Publications

(First paragraph) Chollett et al. (2017) make the case that a local network of marine protected areas (MPAs) enhances fisheries for Caribbean spiny lobster (Panulirus argus) off the coast of Honduras. However, their simulation focused on one ecoregion where self-recruitment is predicted to be among the highest in the Caribbean (Cowen, Paris, & Srinivasan, 2006). The shallow banks and scattered cays of the Honduran-Nicaraguan Rise, separating the Cayman and Colombian basins, create an obstacle to the powerful southern Caribbean jet (Richardson, 2005), fostering an ideal location for topographically steered eddies and larval retention. Local management,whether based on traditional techniques or ...

Transitioning To A New Era In Western United States Water Governance: Examining Sustainable And Equitable Water Policy In The Colorado River Basin, John Gordom Berggren

Environmental Studies Graduate Theses & Dissertations

Water resources around the world face significant challenges in the 21st century. Ecological degradation, expanding populations and shifting demands, climate change, drought, and numerous other factors increasingly limit the ability of water managers to effectively govern these resources without adversely impacting users and ecosystems in disproportionate ways. Accordingly, water governance principles such as sustainability have emerged as possible guiding mechanisms for addressing these challenges and responding to diverse stakeholder needs. Equity is another principle that is often discussed as a component of sustainability, but it is also an important consideration in its own right. Therefore, this dissertation explores the ...
