Assessing Transboundary Wildfire Exposure In The Southwestern United States, Alan A. Ager, Palaiologos Palaiologou, Cody Evers, Michelle A. Day, Ana M.G. Barros

Environmental Science and Management Faculty Publications and Presentations

We assessed transboundary wildfire exposure among federal, state, and private lands and 447 communities in the state of Arizona, southwestern United States. The study quantified the relative magnitude of transboundary (incoming, outgoing) versus nontransboundary (i.e., self-burning) wildfire exposure based on land tenure or community of the simulated ignition and the resulting fire perimeter. We developed and described several new metrics to quantify and map transboundary exposure. We found that incoming transboundary fire accounted for 37% of the total area burned on large parcels of federal and state lands, whereas 63% of the area burned was burned by ignitions within the …

Spatial Analysis Of The Current And Potential Stormwater Management Practices On Grand Valley State University’S Allendale Campus, Kyle Hart Apr 2018

Spatial Analysis Of The Current And Potential Stormwater Management Practices On Grand Valley State University’S Allendale Campus, Kyle Hart

Honors Projects

Low impact development is an alternative to traditional urban design with the goal of reducing the amount of stormwater runoff generated from impermeable surfaces. Increased stormwater runoff can mobilize surface pollutants such as oil, road salt, and heavy metals, as well as accelerate the erosion and slope destabilization near natural waterways. Green infrastructure such as rain gardens and green roofs have been shown to remediate these pollutants and reduce the peak discharge of stormwater during storm events. This study evaluates the current stormwater management practices on the Allendale Campus of Grand Valley State University as well as provides management suggestions …

The Chesapeake Bay Preservation Act: Proposed Modifications To Improve Resilience To Sea Level Rise, Christopher Antoine Apr 2018

The Chesapeake Bay Preservation Act: Proposed Modifications To Improve Resilience To Sea Level Rise, Christopher Antoine

Virginia Coastal Policy Center

There are a number of ways to increase resiliency to sea level rise, and localities should consider all of the potential methods available to them, as not all methods are feasible in every locality. This paper will examine how the CBPA [Chesapeake Bay Preservation Act, the "Act"] currently works to protect water quality and its current capability to help localities improve resilience. It will also consider some potential changes to the CBPA and other programs that may increase the Act’s ability to promote community resilience to sea level rise through rational development while maintaining the water quality benefits that the …

Modeling Spawning Habitat Potential For Chum (Onchorhynchus Keta) And Pink Salmon (O. Gorbuscha) In Relation To Landscape Characteristics In Coastal Southeast Alaska, Bernard Timothy Romey Mar 2018

Modeling Spawning Habitat Potential For Chum (Onchorhynchus Keta) And Pink Salmon (O. Gorbuscha) In Relation To Landscape Characteristics In Coastal Southeast Alaska, Bernard Timothy Romey

Dissertations and Theses

In response to the increasing need for ecosystem services throughout the Southeast Alaska region, decision makers are tasked with balancing the need for natural resources with salmon conservation. However, accurate historical and current information on salmonid population abundance, freshwater distribution, and habitat quality are sparse with limited resolution for large portions of this remote and rugged landscape. Here, I created Intrinsic Potential (IP) models for chum and pink salmon to predict the potential for portions of coastal rivers to provide high-quality spawning habitat. I developed IP models for both species from field redd surveys and synthetic habitat variables derived from …

High-Resolution Water Footprints Of Production Of The United States Mar 2018

High-Resolution Water Footprints Of Production Of The United States

Daugherty Water for Food Global Institute: Faculty Publications

The United States is the largest producer of goods and services in the world. Rainfall, surface water supplies, and groundwater aquifers represent a fundamental input to economic production. Despite the importance of water resources to economic activity, we do not have consistent information on water use for specific locations and economic sectors. A national, spatially detailed database of water use by sector would provide insight into U.S. utilization and dependence on water resources for economic production. To this end, we calculate the water footprint of over 500 food, energy, mining, services, and manufacturing industries and goods produced in the United …

Present And Future Thermal Environments Available To Sharp-Tailed Grouse In An Intact Grassland, Edward J. Raynor, Larkin Powell, Walter H. Schacht Feb 2018

Present And Future Thermal Environments Available To Sharp-Tailed Grouse In An Intact Grassland, Edward J. Raynor, Larkin Powell, Walter H. Schacht

School of Natural Resources: Faculty Publications

Better understanding animal ecology in terms of thermal habitat use has become a focus of ecological studies, in large part due to the predicted temperature increases associated with global climate change. To further our knowledge on how ground-nesting endotherms respond to thermal landscapes, we examined the thermal ecology of Sharp-tailed Grouse (Tympanuchus phasianellus) during the nesting period. We measured site-specific iButton temperatures (TiB) and vegetation characteristics at nest sites, nearby random sites, and landscape sites to assess thermal patterns at scales relevant to nesting birds. We asked if microhabitat vegetation characteristics at nest sites matched the characteristics that directed macrohabitat …

Benefit Relevant Indicators: Ecosystem Services Measures That Link Ecological And Social Outcomes, Lydia Olander, Robert J. Johnston, Heather Tallis, James S. Kagan, Lynn A. Maguire, Stephen Polasky, Dean Urban, James Boyd, Lisa Wainger, Margaret A. Palmer Feb 2018

Benefit Relevant Indicators: Ecosystem Services Measures That Link Ecological And Social Outcomes, Lydia Olander, Robert J. Johnston, Heather Tallis, James S. Kagan, Lynn A. Maguire, Stephen Polasky, Dean Urban, James Boyd, Lisa Wainger, Margaret A. Palmer

Institute for Natural Resources Publications

There is a growing movement in government, environmental non-governmental organizations and the private sector to include ecosystem services in decision making. Adding ecosystem services into assessments implies measuring how much a change in ecological conditions affects people, social benefit, or value to society. Despite consensus around the general merit of accounting for ecosystem services, systematic guidance on what to measure and how is lacking. Current ecosystem services assessments often resort to biophysical proxies (e.g., area of wetland in a floodplain) or even disregard services that seem difficult to measure. Valuation, an important tool for assessing trade-offs and comparing outcomes, is …


The Interactive Effect Of Multiple Stressors On Crustacean Zooplankton Communities In Montane Lakes, Jeffrey Thomas Brittain, Angela L. Strecker Feb 2018

The Interactive Effect Of Multiple Stressors On Crustacean Zooplankton Communities In Montane Lakes, Jeffrey Thomas Brittain, Angela L. Strecker

Environmental Science and Management Faculty Publications and Presentations

Nonnative fish introductions have altered thousands of naturally fishless montane lakes, resulting in cascading food web repercussions. Nitrogen deposition has been recognized as an anthropogenic contributor to acidification and eutrophication of freshwater ecosystems, which may affect the abundance and composition of planktonic communities. This study identified responses of zooplankton communities from two lakes (fish present versus absent) in Mount Rainier National Park to manipulations simulating an episodic disturbance of acidification and eutrophication via nitrogen addition in mesocosms. Zooplankton communities from lakes with different food web structure (i.e., fish present or absent) responded differently to the singular effects of acid and …


Acoustic Surveys Of Bats At Northern Great Plains Parks And Preliminary Results From 2014-16, Daniel S. Licht Feb 2018

Acoustic Surveys Of Bats At Northern Great Plains Parks And Preliminary Results From 2014-16, Daniel S. Licht

United States National Park Service: Publications

Executive Summary

From 2014-16, the Northern Great Plains Inventory & Monitoring Network (Network)—in collaboration with the Midwest Regional Biologist—used acoustic methods to monitor bat populations at 12 Network parks. Six parks were monitored using the nascent North American Bat Monitoring Program (NABat) framework. Six other parks did not meet a priori criteria for inclusion in NABat so they were monitored using similar methods, but a non-systematic sampling frame.

Fifty-five NABat stations were established along with 62 non-NABat stations. Stations were typically monitored for 4-7 nights each year using equipment that records the echolocation calls of bats. Fourteen mobile survey routes …


Global Anthropogenic Phosphorus Loads To Freshwater And Associated Grey Water Footprints And Water Pollution Levels: A High-Resolution Global Study, Mesfin Mekonnen, Arjen Y. Hoekstra Jan 2018

Global Anthropogenic Phosphorus Loads To Freshwater And Associated Grey Water Footprints And Water Pollution Levels: A High-Resolution Global Study, Mesfin Mekonnen, Arjen Y. Hoekstra

Daugherty Water for Food Global Institute: Faculty Publications

We estimate the global anthropogenic phosphorus (P) loads to freshwater and the associated grey water footprints (GWFs) for the period 2002–2010, at a spatial resolution of 5 3 5 arc min, and com- pare the GWF per river basin to runoff to assess the P-related water pollution level (WPL). The global anthro- pogenic P load to freshwater systems from both diffuse and point sources is estimated at 1.5 Tg/yr. More than half of this total load was in Asia, followed by Europe (19%) and Latin America and the Caribbean (13%). The domestic sector contributed 54% to the total, agriculture 38%, …

1. Acoustic telemetry studies have frequently prioritized linear configurations of hydrophone receivers, such as perpendicular from shorelines or across rivers, to detect the presence of tagged aquatic animals. This approach introduces unknown bias when receivers are stationed for convenience at geographic bottlenecks (e.g. at the mouth of an embayment or between islands) as opposed to deployments following a statistical sampling design.

2. We evaluated two-dimensional acoustic receiver arrays (grids: receivers spread uniformly across space) as an alternative approach to provide estimates of survival, movement and habitat use. Performance of variably spaced receiver grids (5–25 km spacing) was evaluated by simulating …


Community-Level Plant–Soil Feedbacks Explain Landscape Distribution Of Native And Non-Native Plants, Andrew Kulmatiski Jan 2018

Community-Level Plant–Soil Feedbacks Explain Landscape Distribution Of Native And Non-Native Plants, Andrew Kulmatiski

Wildland Resources Faculty Publications

Plant–soil feedbacks (PSFs) have gained attention for their potential role in explaining plant growth and invasion. While promising, most PSF research has measured plant monoculture growth on different soils in short-term, greenhouse experiments. Here, five soil types were conditioned by growing one native species, three non-native species, or a mixed plant community in different plots in a common-garden experiment. After 4 years, plants were removed and one native and one non-native plant community were planted into replicate plots of each soil type. After three additional years, the percentage cover of each of the three target species in each community was …

Using Unmanned Aerial Systems For Deriving Forest Stand Characteristics In Mixed Hardwoods Of West Virginia, Henry Liebermann, Jamie Schuler, Michael P. Strager, Angela K. Hentz, Aaron Maxwell

Journal of Geospatial Applications in Natural Resources

Forest inventory information is a principle driver for forest management decisions. Information gathered through these inventories provides a summary of the condition of forested stands. The method by which remote sensing aids land managers is changing rapidly. Imagery produced from unmanned aerial systems (UAS) offer high temporal and spatial resolutions to small-scale forest management. UAS imagery is less expensive and easier to coordinate to meet project needs compared to traditional manned aerial imagery. This study focused on producing an efficient and approachable work flow for producing forest stand board volume estimates from UAS imagery in mixed hardwood stands of West …

Variability Of Rainfall Erosivity And Erosivity Density In The Ganjiang River Catchment, China: Characteristics And Influences Of Climate Change, Xianghu Li, Xuchun Ye

School of Natural Resources: Faculty Publications

Soil erosion is one of the most critical environmental hazards in the world. Understanding the changes in rainfall erosivity (RE) and erosivity density (ED), as well as their affecting factors, at local and catchment scales in the context of climate warming is an important prerequisite of soil erosion prevention and soil loss risk assessment. The present study identified the variability and trends of RE and ED in terms of both time and space in the Ganjiang River catchment over the period of 1960–2012, and also analyzed and discussed the impact of climate change. The results show that RE and ED …
