Characterizing Burn Severity Of Beetle-Killed Forest Stands Leveraging Google Earth Engine-Derived Normalized Burn Ratios, Sofronio Catalino Propios Iii
Characterizing Burn Severity Of Beetle-Killed Forest Stands Leveraging Google Earth Engine-Derived Normalized Burn Ratios, Sofronio Catalino Propios Iii
Graduate Student Theses, Dissertations, & Professional Papers
Following numerous studies, a general consensus on burn severity in forests affected by bark beetle outbreaks has not yet been achieved. The purpose of this study is to characterize burn severities in forest stands affected by mountain pine beetle (MPB) outbreaks, especially in relation to “time since outbreak”, vegetation cover, and topographic factors. This study focuses on wildfires that occurred in the northern Rocky Mountains of Idaho and Montana during the 2012 fire season within forested areas that had previously experienced prior MPB outbreaks. Remote sensing techniques were used to quantify and compare the burn severities of MPB-outbreak stands with …
Remote Sensing Approaches To Predict Forest Characteristics In Northwest Montana, Ryan P. Rock
Remote Sensing Approaches To Predict Forest Characteristics In Northwest Montana, Ryan P. Rock
Graduate Student Theses, Dissertations, & Professional Papers
Remote sensing can be utilized by land management organizations to save money and time. Mapping vegetation using either aerial photographs or satellite imagery and the applications for forest management are of particular interest to the Montana Department of Natural Resources. In 2018, the organization began a pilot program to test the incorporation of raster analysis of remotely sensed data into their inventory program and had limited success. This analysis identified two areas of improvement: the selection method of inventory plots and the imagery used for classification and metrics. This study found that selecting inventory plots using a generalized random tessellation …
Protecting Biodiversity On National Forests: The Evolution And Implementation Of Forest Planning Regulations, Anna Wearn
Protecting Biodiversity On National Forests: The Evolution And Implementation Of Forest Planning Regulations, Anna Wearn
Graduate Student Theses, Dissertations, & Professional Papers
In 2012, the U.S. Forest Service (USFS) promulgated new forest planning regulations that significantly altered national forest management. One of the most controversial and important advancements was the inclusion of what were meant to be stronger biodiversity protections. An analysis of USFS’s rationale in revising the biodiversity regulations provides insights into how to interpret the substantively and procedurally new ecosystem and species protections. Examining this regulatory history reveals three key changes to the manner in which national forests are required to manage and monitor biodiversity: 1) a greater reliance on science to inform planning, 2) a new emphasis on ecological …
Ethical Eating: Overcoming Alienation In The Industrial Food System By Aligning Our Practices With Our Principles, André Kushnir
Ethical Eating: Overcoming Alienation In The Industrial Food System By Aligning Our Practices With Our Principles, André Kushnir
Graduate Student Theses, Dissertations, & Professional Papers
This thesis arose out of a moment of discord, while an environmental philosopher was eating blackberries in the middle of a blizzard in Missoula, Montana. What follows is an attempt to bridge the gap between our principles and our practices, by asking the questions: What does ethical eating look like? Is it possible within our current industrial food system? and If not, what needs to change? Responding to the publication of the 2019 EAT-Lancet report, this essay moves beyond thinking of ethical eating as “healthy” and “sustainable” and challenges the networks of suffering and labour that we take for …
Global And Regional Perspectives On Large-Landscape And Transboundary Conservation, Sanober R. Mirza
Global And Regional Perspectives On Large-Landscape And Transboundary Conservation, Sanober R. Mirza
Graduate Student Theses, Dissertations, & Professional Papers
With the growing pressure of environmental degradation and exploitation to social and ecological landscapes around the world, conservationists are looking for new approaches to address the complex nature of transboundary issues. Large-landscape conservation supports conservation and management of ecosystems, wildlife, and resources in a more holistic approach that extends beyond protected area boundaries. Transboundary conservation, a distinct form of large-landscape conservation, operates across political and spatial scales by involving two or more countries cooperating to protect a border resource or ecosystem. Though the recognition of large-landscape and transboundary conservation is growing, there is limited understanding of trends across these types …
Change Is The Only Constant: A Snowpack Retention Analysis And Climate Vulnerability Road Map For The Skalkaho Creek Sub-Basin, Zachary Freeman Goodwin
Change Is The Only Constant: A Snowpack Retention Analysis And Climate Vulnerability Road Map For The Skalkaho Creek Sub-Basin, Zachary Freeman Goodwin
Graduate Student Theses, Dissertations, & Professional Papers
Climate change is impacting the whole of North America, although the impacts differ depending on regional geography. In the Intermountain West, climate change is contributing to lower overall snowpack totals and diminished late season streamflows. These changes will likely contribute to vulnerabilities in how much water is available to irrigators, municipalities, and fisheries dependent upon a consistent yearly flow of meltwater. This paper explores how snowpack retention has changed via the NASA dataset Daymet, which provides gridded estimates of weather parameters including Snow Water Equivalent in the Bitterroot River Basin of western Montana. This analysis showed that snowpack retention from …
Water For Fish And Farms: An Examination Of Instream Flow Programs In Montana Using Spatially-Explicit Water Rights Data, Anna Leigh Crockett
Water For Fish And Farms: An Examination Of Instream Flow Programs In Montana Using Spatially-Explicit Water Rights Data, Anna Leigh Crockett
Graduate Student Theses, Dissertations, & Professional Papers
The state-level institutions governing water use in the western United States have increasingly come under pressure and scrutiny related to their inability to navigate water use conflicts in recent decades. Rapid population growth and shifting public values towards leaving water instream for recreational and environmental purposes pose challenges to Montana water supplies which are predominantly allocated for irrigated agriculture. Additionally, while water scarcity and unpredictable availability are not new dilemmas in Montana, the rate at which climate change is driving shifts in the distribution, timing, and availability of water supplies is unprecedented. Current water policies may not be nimble enough …
Prioritizing Parcels For Conservation Easements Using Least-Cost Path Analyses Of Land Ownership: Case Study Within Theorized Grizzly Bear Migration Corridors Of Western Montana, Joseph H. Offer
Graduate Student Theses, Dissertations, & Professional Papers
As the world’s human population has grown and converted large natural habitats to human dominated landscapes, the planet’s biodiversity has decreased. To combat the loss of biodiversity from human development, many conservation professionals champion the concept of conservation corridors between intact habitats. Conservation corridors, made up of protected land, serve as a connection for wildlife populations to intermix genetics and, subsequently, help reduce the risk of extinction. The ideal geographic location of corridors is generally determined through geographic information system modeling using biophysical conditions and theorized animal movement. However, the resulting corridors are often expansive and protecting entire corridors is …

Comparing Fence Modeling And Mapping Approaches To Support Wildlife Management And Research In Southwest Montana, Simon Albert Buzzard
Graduate Student Theses, Dissertations, & Professional Papers
Fences pose significant challenges to wildlife movement, but their effects are difficult to quantify because fence location and fence type data are lacking on a global scale. We developed a fence location and density model in southwest Montana, USA to provide data to researchers and managers, and test whether previous models could be applied to a new region and retain suitable levels of statistical accuracy. Our model used local expert opinion to inform how road, land cover, and ownership spatial layers interacted to predict fence locations. We validated the model against fence data collected on random 3.2 km road transects …
Understanding And Measuring Net Positive Business Strategies, Luke Ruffner Robinson
Understanding And Measuring Net Positive Business Strategies, Luke Ruffner Robinson
Graduate Student Theses, Dissertations, & Professional Papers
Despite their attempts to mitigate ecological impacts through sustainability initiatives, businesses are a major cause of the world's ecological problems. Some progressive businesses are attempting to move beyond “net zero” in terms of achieving neutral environmental impacts and instead are now pursuing a goal of net positive. Net positive refers to the idea that business activities could contribute value-added benefits to earth’s ecological systems, for example, by using technologies that sequester and store carbon. However, except for a handful of high-profile corporate case studies, little is known about how companies are developing their strategies to become net positive and …
