Soil Conservation Efforts Affecting And Implementations To Help Tree Growth In Iceland, Justin Lawlor 2018 Embry-Riddle Aeronautical University

Soil Conservation Efforts Affecting And Implementations To Help Tree Growth In Iceland, Justin Lawlor

Student Works

The purpose of this research was to understand and project the opinions of the public in Iceland on soil conservation and current efforts. The issue of soil erosion dates back to settlement around 1,100 years ago. The loss of vegetation from deforestation and grazing exposes the land to the effects of wind, water, and other devastating elements, leading it to erode away. The Soil Conservation Service of Iceland (SCSI) was developed to combat this issue over 100 years ago with efforts including planting trees, promoting safe farming practices, and replenishing the land. Interviews were conducted with various individuals, including ...


I-Tree Landscape: A Case Study In Best Practices For Education And Dissemination For Multiple User Groups, Margaret M. Abood 2018 DePaul University

I-Tree Landscape: A Case Study In Best Practices For Education And Dissemination For Multiple User Groups, Margaret M. Abood

DePaul Discoveries

The urban ecosystems we inhabit provide essential ecosystem services to humans, such as air pollution removal, as well as effective means to avoid costs related to urban development, such as stormwater treatment. A better understanding of the value of ecosystem services and their spatial distribution in urban areas is vital to widespread, wholistic understanding of the relationship of environmental, economic, and social conditions. As such, it should be a component of education in grades 6-12, college, and continuing education. i-Tree Landscape is a free, online model developed by the USDA Forest Service in which users can select a geography (i ...


A Quantitative Analysis Of The Effects Of Urbanization, Mesophication And Prescribed Burns On Oak Woodlands In The Chicago Metropolitan Area, Chad Populorum 2018 Augustana College, Rock Island Illinois

A Quantitative Analysis Of The Effects Of Urbanization, Mesophication And Prescribed Burns On Oak Woodlands In The Chicago Metropolitan Area, Chad Populorum

Celebration of Learning

Urban expansion has had devastating impacts on forest ecosystems, especially within the past century. Human attempts to dominate nature have diminished natural disturbance regimes, which have maintained the biodiversity and historic composition of these ecosystems. Fires have been a prominent force in maintaining the structure of oak, hickory and other heliophytic (sun loving and fire-adapted) forest systems. Human induced fire suppression has led to mesophication across North America. Mesophication is the transition from drier conditions with open canopies to wetter conditions with closed canopies. These new conditions decrease the survival rates of these important species and begin to favor mesophytic ...


Radical Social Ecology As Deep Pragmatism: A Call To The Abolition Of Systemic Dissonance And The Minimization Of Entropic Chaos, Arielle Brender 2018 Fordham University

Radical Social Ecology As Deep Pragmatism: A Call To The Abolition Of Systemic Dissonance And The Minimization Of Entropic Chaos, Arielle Brender

Student Theses 2015-Present

This paper aims to shed light on the dissonance caused by the superimposition of Dominant Human Systems on Natural Systems. I highlight the synthetic nature of Dominant Human Systems as egoic and linguistic phenomenon manufactured by a mere portion of the human population, which renders them inherently oppressive unto peoples and landscapes whose wisdom were barred from the design process. In pursuing a radical pragmatic approach to mending the simultaneous oppression and destruction of the human being and the earth, I highlight the necessity of minimizing entropic chaos caused by excess energy expenditure, an essential feature of systems that aim ...


Building Resistance And Resilience: Regeneration Should Not Be Left To Chance, James N. Long, Marcella Windmuller-Campione, R. Justin DeRose 2018 Utah State University

Building Resistance And Resilience: Regeneration Should Not Be Left To Chance, James N. Long, Marcella Windmuller-Campione, R. Justin Derose

Wildland Resources Faculty Publications

Contemporary forest planning has tasked managers with developing goals associated with resistance and resilience. In practice, silviculturists use forest structure and tree species composition to characterize goals and desired future conditions, write prescriptions, and monitor outcomes associated with resistance and resilience. Although rarely discussed in the exploding literature relating to forest resistance and resilience, silvicultural regeneration methods are important and underutilized tools to meet these goals. We propose alternative silvicultural systems for building resistance and resilience to two common large-scale bark beetle disturbance agents in the Intermountain West, United States: mountain pine beetle (Dendroctonus ponderosae Hopkins) and spruce beetle (Dendroctonus ...


Mitigating Bioiversity Loss Of Native Plants, Jamie Ana Grigonis 2018 Fordham University

Mitigating Bioiversity Loss Of Native Plants, Jamie Ana Grigonis

Student Theses 2015-Present

Growing up harvesting from my own vegetable garden and going from nursery to nursery with my mother, it has been extremely evident that plant biodiversity is more than just privet along driveways and carnations in window boxes. Plant biodiversity is often overlooked but crucial to having a healthy and thriving environment. Without certain plants, our ecosystems will crumble and this needs to be addressed now while it’s still at a level we can grow from. In my internship I am working alongside the director of the Thain Family Forest at the New York Botanical Gardens in order to get ...


Initial Assessment Of Canopy Fuel Factors In Forested Areas Of The Netherlands, Alan Hibler 2018 Stephen F. Austin State University

Initial Assessment Of Canopy Fuel Factors In Forested Areas Of The Netherlands, Alan Hibler

Electronic Theses and Dissertations

The changing climate in the Netherlands has created the need to better understand how the forested communities and their structures will be affected by fire and to better estimate the impact of those fires. This study is part of a continuing collaboration between the Stephen F. Austin State University’s Arthur Temple College of Forestry and Agriculture and the Instittut Fysieke Veiligheid to assess fuel loads in the Netherlands to develop and improve models to estimate fire behavior. Data to estimate canopy bulk density for modelling canopy fire behavior were collected in the Netherlands for Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco ...


Challenges And Solutions For National Park Service Civil War Sites Working With African American Communities, Rolonda Teal 2018 Stephen F. Austin State University

Challenges And Solutions For National Park Service Civil War Sites Working With African American Communities, Rolonda Teal

Electronic Theses and Dissertations

The objectives of this project were to determine the ways in which National Park Service (NPS) sites with a Civil War component are connecting or not with African American visitors and non-visitors. In order to meet the overarching objectives, two approaches were used which consisted of direct contact with the NPS sites and administering a site-specific questionnaire. Multiple attempts were made to contact 81 national parks, monuments, battlefields, historic sites, and other type park designations. Of the 81 sites, 55 national park units responded to an eight plus two sub-question questionnaire. Interpreters at each site were asked about interpretive programming ...


Climate Sensitivity And Potential Vulnerability Of Guatemalan Fir (Abies Guatemalensis) Forests In Totonicapán, Guatemala, Talia G. Anderson, Daniel Griffin, Kevin Anchukaitis, Diego Pons, Matthew Taylor 2018 University of Arizona

Climate Sensitivity And Potential Vulnerability Of Guatemalan Fir (Abies Guatemalensis) Forests In Totonicapán, Guatemala, Talia G. Anderson, Daniel Griffin, Kevin Anchukaitis, Diego Pons, Matthew Taylor

Journal of Latin American Geography

Despite continued forest loss and extensive demand for wood products throughout Guatemala, the locally managed and protected forests of Totonicapán remain some of the most intact within the country. Here, we study the growth rings of Guatemalan fir (Pinaceae; Abies guatemalensis Rehder; pinabete) at Totonicapán to assess environmental influences on tree growth and the potential vulnerability of these forests to climate change in the western highlands. We find that late summer and dry season precipitation are critical drivers in annual ring-width variability and that tree growth responds negatively to warm sea surface temperature anomalies in the eastern tropical Pacific. Considering ...


Managing For Multiple Objectives In Southwestern Forests: Evaluating The Trade-Offs Between Enhancing Mexican Spotted Owl Nest Habitat And Mitigating Potential Crown Fire, Daniel C. Deane McKenna 2018 Utah State University

Managing For Multiple Objectives In Southwestern Forests: Evaluating The Trade-Offs Between Enhancing Mexican Spotted Owl Nest Habitat And Mitigating Potential Crown Fire, Daniel C. Deane Mckenna

All Graduate Theses and Dissertations

The Forest Inventory and Analysis (FIA), the United States’ forest census, measured sixty-six Mexican spotted owl nest stands in order gain insight into the structure and composition of the nest habitat of this threatened species. I used these data, along with the greater FIA database and the Forest Vegetation Simulator to explore questions surrounding the management of Mexican spotted owl habitat, specifically how to balance the objective of sustaining and enhancing nest habitat in face of increasing forest fire size and severity in the Southwest. My research consisted of three studies. The first study quantified the structure and composition of ...


Low Offspring Survival In Mountain Pine Beetle Infesting The Resistant Great Basin Bristlecone Pine Supports The Preference-Performance Hypothesis, Erika L. Eidson, Karen E. Mock, Barbara J. Bentz 2018 Utah State University

Low Offspring Survival In Mountain Pine Beetle Infesting The Resistant Great Basin Bristlecone Pine Supports The Preference-Performance Hypothesis, Erika L. Eidson, Karen E. Mock, Barbara J. Bentz

Wildland Resources Faculty Publications

The preference-performance hypothesis states that ovipositing phytophagous insects will select host plants that are well-suited for their offspring and avoid host plants that do not support offspring performance (survival, development and fitness). The mountain pine beetle (Dendroctonus ponderosae), a native insect herbivore in western North America, can successfully attack and reproduce in most species of Pinus throughout its native range. However, mountain pine beetles avoid attacking Great Basin bristlecone pine (Pinus longaeva), despite recent climate-driven increases in mountain pine beetle populations at the high elevations where Great Basin bristlecone pine grows. Low preference for a potential host plant species may ...


The Economic Contribution Of Stewardship Contracting: Two Case Studies From The Mount Hood National Forest, Jean M. Daniels, Max Nielsen-Pincus, Mike Paruszkiewicz, Nathan Poage 2018 USDA Forest Service, Pacific Northwest Research Station, Portland, OR

The Economic Contribution Of Stewardship Contracting: Two Case Studies From The Mount Hood National Forest, Jean M. Daniels, Max Nielsen-Pincus, Mike Paruszkiewicz, Nathan Poage

Environmental Science and Management Faculty Publications and Presentations

We conducted an economic analysis of two case study stewardship contracts on the Mount Hood National Forest in western Oregon. Stewardship contracting has been embraced by some federal managers to achieve restoration goals while providing economic benefits to local communities. Little is known about economic contributions from stewardship contracts, including how they compare against Secure Rural Schools funding or the century-old payments to counties revenue sharing system. Using expenditure data from sale purchasers, contractors, and fiscal agents, we developed methodology to track spending and used IMPLAN software to estimate economic contributions and multipliers. Results showed that (1) commercial thinning, service ...

This plan was developed by the students of the Spring 2018 BIO 255: Conservation Biology course, instructed by Dr. Jameson Chace, Associate Professor of biology at Salve Regina University. As part of a curriculum geared towards civic engagement, the class focused on creating and optimizing strategies that can be applied to the ten-year plan. These strategies were ...


Comparative Study Of Photosynthesis Rates Between Native Red Maple And Invasive Norway Maple In The Eastern Deciduous Forest, Evan M. Bourtis, Lindsey R. Heckman 2018 St. John Fisher College

Comparative Study Of Photosynthesis Rates Between Native Red Maple And Invasive Norway Maple In The Eastern Deciduous Forest, Evan M. Bourtis, Lindsey R. Heckman

The Review: A Journal of Undergraduate Student Research

Invasive species, such as the Norway Maple, are often able to outcompete native species, such as the Red Maple by performing more efficiently in the environment compared to the native species. In this study, we examined if the Norway maple was able to outcompete the Red Maple in the Eastern Deciduous Forest because the Norway Maple had a higher rate of photosynthesis. The study found that the Norway Maple leaves had a slightly higher rate of carbon dioxide consumption than Red Maple leaves and that the Red Maple leaves had a higher rate of oxygen production compared to the Norway ...

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 ...

Spatiotemporal Patterns Of Unburned Areas Within Fire Perimeters In The Northwestern United States From 1984 To 2014, Arjan J. H. Meddens, Crystal A. Kolden, James A. Lutz, John T. Abatzoglou, Andrew T. Hudak 2018 University of Idaho

Spatiotemporal Patterns Of Unburned Areas Within Fire Perimeters In The Northwestern United States From 1984 To 2014, Arjan J. H. Meddens, Crystal A. Kolden, James A. Lutz, John T. Abatzoglou, Andrew T. Hudak

Wildland Resources Faculty Publications

A warming climate, fire exclusion, and land cover changes are altering the conditions that produced historical fire regimes and facilitating increased recent wildfire activity in the northwestern United States. Understanding the impacts of changing fire regimes on forest recruitment and succession, species distributions, carbon cycling, and ecosystem services is critical, but challenging across broad spatial scales. One important and understudied aspect of fire regimes is the unburned area within fire perimeters; these areas can function as fire refugia across the landscape during and after wildfire by providing habitat and seed sources. With increasing fire activity, there is speculation that fire ...
