Place-based management in the open ocean faces unique challenges in delineating boundaries around temporally and spatially dynamic systems that span broad geographic scales and multiple management jurisdictions, especially in the 'high seas'. Geospatial technologies are critical for the successful design of pelagic conservation areas, because they provide information on the spatially and temporally dynamic oceanographic features responsible for driving species distribution and abundance in the open ocean, the movements of protected species, and the spatial patterns of distribution of potential threats. Nevertheless, there are major challenges to implementing these geospatial approaches in the open ocean. This Theme Section seeks to …

Land Cover Mapping And Change Analysis At The Tensleep Preserve In Wyoming, Tyler Richard Grupa
All Graduate Theses, Dissertations, and Other Capstone Projects
Mapping land cover and land cover change are important, especially for land managers who protect natural lands and generate restoration projects. Accurate land cover assessment of rangelands can be difficult because the spectral difference between plant species may be minimal. The goal of this research is to map the land cover in the Tensleep Preserve and highlight change that has occurred over the past twenty-three years using the Feature Analyst extension. The land cover change map will highlight significant changes and Feature Analyst will accurately identify different land covers using historical aerial photographs and ground truthing data collected in 2013. …
Spatial Analysis Of Distributions And Habitat Conditions Of Fallopia Japonica (Japanese Knotweed) Invasive Species Applying Unmanned Helicopter Remote Sensing, Jiazhen Zhang
Great Lakes Center Masters Theses
Abstract:
Fallopia japonica (Japanese knotweed) is a perennial herbaceous plant that is native to East Asia. It is considered as one of the worst invasive species worldwide because of its serious impact on biological diversity and human activities (Lowe et al., 2001). Once established, Japanese knotweed forms dense stands that shade and crowd out native plant species. The objectives of this research were to verify and confirm the distribution of Japanese knotweed as published online by the New York Department of Environmental Conservation (DEC) – iMap and to identify the geographic areas of spreading and the local habitat conditions. In …
Tracking Of Karst Contamination Using Alternative Monitoring Technologies: Hidden River Cave Kentucky, Caren Raedts, Christopher Smart
Tracking Of Karst Contamination Using Alternative Monitoring Technologies: Hidden River Cave Kentucky, Caren Raedts, Christopher Smart
Sinkhole Conference 2015
Karst groundwater contamination presents great challenges for efficient monitoring because of rapid, discrete transport and the diversity of contaminants. Here a low cost approach is described and applied to Hidden River Cave, Kentucky, where a long history of contamination has been experienced. Local knowledge was acquired through informal interviews and coupled with observations of contaminant residues, faunal distributions and fluorescence spectra in the cave. The resulting patterns were interpreted using Google Earth and Street View to identify specific contaminant sources in the affected sub-catchment of the cave. Despite success in matching contaminant sources with the contamination history and pattern, the …
Using Future Benefits To Set Conservation Priorities For Wetlands, Samuel B. Merrill
Using Future Benefits To Set Conservation Priorities For Wetlands, Samuel B. Merrill
Journal of Ocean and Coastal Economics
In an era of rising sea levels, costal land managers including land trust representatives, municipal planners, and others contributing to decisions about whether to develop or protect coastal parcels do not have viable means of evaluating future values on wetlands that will be created when sea levels rise. This project develops and tests a software modeling approach to help address this issue, in combination with a novel, expert-opinion driven benefit-cost framework. The beta test used three parcels in Scarborough, Maine: Hampton Circle, Maine Audubon, and Pine Point. It used a group of experts to 1) allocate initial values to these …

No time to waste: Crowdsourcing global wastewater treatment data
Worldwide, over 80 percent of wastewater is discharged into water bodies without undergoing treatment, severely impairing human well-being and ecosystem vitality along the way. National performance on wastewater treatment is difficult to quantify and is poorly understood due to a lack of common definitions, poor data collection standards, and limited historical data. To address this, the Yale Environmental Performance Index (EPI), a research group that produces a biennial ranking of country-level environmental performance, developed a first-of-its kind national wastewater treatment indicator.[1]
The indicator assesses wastewater treatment performance for 183 countries, …

Monitoring Invasive Plant Species: Summer Internship At Habitat Wildlife Sanctuary, Belmont, Massachusetts, Holly M. Zanoni
Sustainability and Social Justice
Habitat Wildlife Sanctuary, located in Belmont, Massachusetts is a dynamic suburban sanctuary that effectively upholds Mass Audubon’s three-part mission of advocacy, conservation, and education. Invasive plants threaten ecological integrity; however, proactive measures are taken to mitigate further encroachment. This is accomplished by surveying and taking inventory for presence of invasive species, then prioritizing them, and finally by incorporating high priority species into the immediate management strategy. Four invasive plants were formally analyzed using geographic information science during the 2014 growing season: Garlic mustard, Black swallowwort, Japanese knotweed, and Dame’s Rocket. The resulting density maps detected pattern changes from 2011, 2012, …

Using Kriging, Cokriging, And Gis To Visualize Fe And Mn In Groundwater, Crystal Johnson
Electronic Theses and Dissertations
For aesthetic, economic, and health-related reasons, allowable concentrations of iron (Fe) and manganese (Mn) found present in drinking water are 0.3 mg/L and 0.05 mg/L, respectively. Water samples taken from private drinking wells in the rural communities within Buncombe County, North Carolina contain amounts of these metals in concentrations higher than the suggested limits. This study focused on bedrock geology, elevation, saprolite thickness, and well depth to determine factors affecting Fe and Mn. Using ArcGIS 10.2, spatial trends in Fe and Mn concentrations ranges were visualized, and estimates of the metal concentrations were interpolated to unmonitored areas. Results from this …
Mapping Ancient Baldcypress Forests For Conservation At Black River, North Carolina, Jordan Nichole Burns
Mapping Ancient Baldcypress Forests For Conservation At Black River, North Carolina, Jordan Nichole Burns
Graduate Theses and Dissertations
A few ancient baldcypress-bottomland hardwood forests survive across the southeastern United States in a mosaic of remnant old-growth stands left untouched by extensive logging during the early 20th century. Uncut stands in the Southeast that survived centuries of disturbance following European settlement tended to be too senescent and non-commercial to justify logging. Remnant ancient baldcypress forests at Black River, North Carolina, appear to contain the oldest living trees in eastern North America and The Nature Conservancy has protected several of these stands. However, the full extent of ancient bottomland forests along Black River is not known and many valuable tracts …
Signed Peer Reviews As A Means To Improve Scholarly Publishing, Linwood H. Pendleton
Signed Peer Reviews As A Means To Improve Scholarly Publishing, Linwood H. Pendleton
Journal of Ocean and Coastal Economics
Peer review is a necessary process with a long history of complaints, including over-solicitation of a small number of reviewers, delays, inadequate numbers of reviewers, and a lack of incentives to provide strong reviews or avoid reviews with little helpful information for the author. In the era of Web-based distribution of research, through working paper or project reports, anonymous peer reviews are much less likely. The Journal of Ocean and Coastal Economics will use signed peer reviews and an open communication process among authors, reviewers, and editors. This approach, to be developed over time, should lead to stronger communication of …

Who Is At The Forest Restoration Table? Final Report On The Blue Mountains Forest Stewardship Network, Phase 1, Rebecca J. Mclain, Kirsten Wright, Lee Cerveny
Institute for Sustainable Solutions Publications and Presentations
Forest collaboratives have emerged throughout the western U.S. as a governance model to address complex ecological challenges that occur at the landscape scale across multiple landownerships and jurisdictional boundaries. Collaborative groups typically involve multiple parties with diverse interests working together to address complex management challenges. Collaboratives often provide input on or make recommendations about public lands actions and decisions. The Blues Stewardship Project was developed to better understand the size, composition, participation, and diversity of forest collaboratives and to identify organizations that may not currently be represented at the collaborative ‘table.’
The study focuses on five collaborative groups in the …

Estimation Of Crop Gross Primary Production (Gpp): Ii. Do Scaled Modis Vegetation Indices Improve Performance?, Qingyuan Zhang, Yen-Ben Cheng, Alexei I. Lyapustin, Yujie Wang, Xiaoyang Zhang, Andrew Suyker, Shashi Verma, Yanmin Shuai, Elizabeth M. Middleton
GSCE Faculty Publications
Satellite remote sensing estimates of gross primary production (GPP) have routinely been made using spectral vegetation indices (VIs) over the past two decades. The Normalized Difference Vegetation Index (NDVI), the Enhanced Vegetation Index (EVI), the green band Wide Dynamic Range Vegetation Index (WDRVIgreen), and the green band Chlorophyll Index (CIgreen) have been employed to estimate GPP under the assumption that GPP is proportional to the product of VI and photosynthetically active radiation (PAR) (where VI is one of four VIs: NDVI, EVI, WDRVIgreen, or CIgreen). However, the empirical regressions between VI*PAR and …
Mitigation And Beautification: Placing Rain Gardens In The Keystone Neighborhood Of Rock Island, Illinois, Rosalie K. Starenko
Mitigation And Beautification: Placing Rain Gardens In The Keystone Neighborhood Of Rock Island, Illinois, Rosalie K. Starenko
Independent Research Projects
With new stormwater management regulations, cities are looking for strategies to reduce urban runoff, and rain gardens are one of several strategies that capture runoff and encourage infiltration and evaporation. In doing so, pollution from runoff is mitigated and combined sewer systems experience fewer overflow events. I argue as well that the implementation of rain gardens would act as a movement for neighborhood beautification. This research develops a new methodology for placing rain gardens that: 1) maximizes the aesthetic value of the gardens by favoring high-visibility locations and 2) targets locations that would best benefit from reduced stormwater runoff. The …

Analyses Of Potential Ravine And Bluff Stabilization Sites Within The Blue Earth And Le Sueur River Basins, Anna My-Tien T. Tran
All Graduate Theses, Dissertations, and Other Capstone Projects
The United States Environmental Protection Agency (USEPA) has listed much of the Upper Mississippi River (UMR) basin as impaired waters due to excessive turbidity, sedimentation, and nutrient loading. Of particular importance are the associated environmental problems (e.g. eutrophication, habitat and wetland loss, loss of biodiversity, and changes in water quality) that have developed within Lake Pepin, a popular recreational riverine lake of the UMR. Three major drainages contribute to these issues and empty in to the UMR near Lake Pepin - the Minnesota River Basin (MRB), St. Croix River, and UMR. The MRB makes up approximately one-third of the drainage …
Using Storm-Watersheds And A Multi-Criteria Decision Model For Biodiversity Conservation In An Urban Environment, Christina M. Chiappetta
Using Storm-Watersheds And A Multi-Criteria Decision Model For Biodiversity Conservation In An Urban Environment, Christina M. Chiappetta
Legacy Theses & Dissertations (2009 - 2024)
Many planning and land use decisions in New York State are controlled at the local (town or municipal) level, not an optimal scale for planning and implementing resource conservation management. Watershed boundaries provide a more ecologically meaningful scale for conservation, because they capture a full range of natural ecosystem processes that span political boundaries. However, defining an urban watershed is complicated by stormwater infrastructure, so standard topographic watershed boundaries may be inadequate for urban resource conservation even when applied at the watershed scale. Storm-watersheds distort both municipal and watershed boundaries, because the flows are redirected in ways that are often …
A Gis Assessment Of Ecoregion Representation In Chile's Existing And Proposed Integrated Network Of Protected Areas, Jessica Schutz
A Gis Assessment Of Ecoregion Representation In Chile's Existing And Proposed Integrated Network Of Protected Areas, Jessica Schutz
Graduate Student Theses, Dissertations, & Professional Papers
Chile's state designated protected areas are reported to show representation bias and to be unable to meet conservation goals. Private protected areas are considered an important tool to resolve these issues, which has led to support for increasing the role of private protected areas in Chile and creating an integrated public-private protected area network. But the validity of the capacity of private protected areas to fix Chile's state protected area network bias, and the advantage of creating an integrated protected area network, have not been assessed. This study uses the most recent data on Chile's state, private, and international protected …

Station Exposure And Resulting Bias In Temperature Observations: A Comparison Of He Kentucky Mesonet And Asos Data, James Kyle Thompson
Masters Theses & Specialist Projects
Station siting, exposure, instrumentation, and time of observations influence longterm climatic records. This thesis compared and analyzed temperature data from four Kentucky Mesonet stations located in Fayette (LXGN), Franklin (LSML), Clark (WNCH), and Bullitt (CRMT) counties to two nearby Automated Surface Observation Systems (ASOS) stations in Kentucky. The ASOS stations are located at Louisville International Airport (Standiford Field - KSDF) and at Lexington Airport (Blue Grass Field - KLEX). The null hypothesis states that there is no significant difference in temperature measurements between the two types of stations. To quantify the differences in temperature measurements, geoprofiles and the following statistical …

Sustainability Planning, Environmental Justice And Climate Change: Applications Of The Long Island Markal Model, David S. Friedman, Yehuda Klein, Jose Pillich, Michael T. Sullivan
Suburban Sustainability
As pointed out by many authors, sustainability is often vague and amorphous (See, for example, Dovers, 1989; Faber, et al, 2005; Glavič, et al. 2007). There is a clear need to make analytical and data-driven analyses of established and or proposed plans. MARKAL (MARKet ALlocation model) is an analytical tool that can be used characterize the impacts of sustainability plans at multiple spatial scales: global, national, regional, and local. In this study we apply the Long Island MARKAL model to answer three interrelated issues: 1, the development and incremental improvement of local and regional sustainability plans; 2, the impact of …

No More Hidden Secrets: Human Rights Violations And Remote Sensing, Tommy O'Connell, Stephen Young
Genocide Studies and Prevention: An International Journal
Aim: This study used both high resolution and medium resolution satellite imagery to test three semi-automated remote sensing methods, in an attempt to identify useful tools to support eye-witness testimony and reports on human rights violations. As huts are routinely burned down during attacks on a village, particularly in Sudan, the number of huts and villages burned can be used to corroborate on-the-ground reports.
Methods: Three remote sensing methods (Supervised Classification, Change Detection, and Feature Extraction) were performed on imagery from both before the attacks in February 2006 and after the attacks to examine any useful trends that could be …

Use Of Unmanned Aerial Vehicles (Uav) For Urban Tree Inventories, Brian Ritter
Use Of Unmanned Aerial Vehicles (Uav) For Urban Tree Inventories, Brian Ritter
All Theses
In contrast to standard aerial imagery, unmanned aerial systems (UAS) utilize recent technological advances to provide an affordable alternative for imagery acquisition. Increased value can be realized through clarity and detail providing higher resolution (2-5 cm) over traditional products. Many natural resource disciplines such as urban forestry will benefit from UAS. Tree inventories for risk assessment, biodiversity, planning, and design can be efficiently achieved with the UAS. Recent advances in photogrammetric processing have proved automated methods for three dimensional rendering of aerial imagery. Point clouds can be generated from images providing additional benefits. Association of spatial locational information within the …

An ensemble approach is used to examine the sensitivity of smoke loading and smoke direct radiative effect in the atmosphere to uncertainties in smoke emission estimates. Seven different fire emission inventories are applied independently to WRF-Chem model (v3.5) with the same model configuration (excluding dust and other emission sources) over the northern sub-Saharan African (NSSA) biomass-burning region. Results for November and February 2010 are analyzed, respectively representing the start and end of the biomass burning season in the study region. For February 2010, estimates of total smoke emission vary by a factor of 12, but only differences by factors of …
Interannual Variation In Biomass Burning And Fire Seasonality Derived From Geostationary Satellite Data Across The Contiguous United States From 1995 To 2011, Xiaoyang Zhang, Shobha Kondragunta, David Roy
Interannual Variation In Biomass Burning And Fire Seasonality Derived From Geostationary Satellite Data Across The Contiguous United States From 1995 To 2011, Xiaoyang Zhang, Shobha Kondragunta, David Roy
GSCE Faculty Publications
Wildfires exhibit a strong seasonality that is driven by climatic factors and human activities. Although the fire seasonality is commonly determined using burned area and fire frequency, it could also be quantified using biomass consumption estimates that directly represent biomass loss (a combination of the area burned and the fuel loading). Therefore, in this study a data set of long-term biomass consumed was derived from geostationary satellite data to explore the interannual variation in the fire seasonality and the possible impacts of climate change and land management practices across the Contiguous United States (CONUS). Specifically, daily biomass consumed data were …

In order to inform natural resource policy and land management decisions, landscape values mapping (LVM) is increasingly used to collect data about the meanings that people attach to places and the activities associated with those places. This type of mapping provides geographically referenced data on areas of high density of values or associated with different types of values. This article focuses on issues and challenges that commonly occur in LVM, drawing on lessons learned in the US Forest Service Olympic Peninsula Human Ecology Mapping Project. The discussion covers choosing a spatial scale for collecting data, creating the base map, developing …
