I-Tree Landscape: A Case Study In Best Practices For Education And Dissemination For Multiple User Groups, Margaret M. Abood
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, 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
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, 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, 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, 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 ...
The Economic Contribution Of Stewardship Contracting: Two Case Studies From The Mount Hood National Forest, 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 ...

Utilizing Gis To Locate Endangered Gravel Hill Prairies Of The Wabash River Valley, 2018 Purdue University
Utilizing Gis To Locate Endangered Gravel Hill Prairies Of The Wabash River Valley, Ryan W.R. Schroeder
Engagement & Service-Learning Summit: Reciprocal & Sustainable Partnerships
The Gravel Hill Prairies (GHP’s) of the Wabash River Valley are an endangered ecosystem in the state of Indiana and provide optimal growing conditions for a number of state endangered plants. Currently only four remnants are known to exist near Lafayette, IN, found by a previous study conducted in 1980 by Post, Bacone, and Aldrich (Proceedings of the Indiana Academy of Science, 1984, vol. 94: 457-464). These unique ecosystems have been found to occur almost exclusively on soils classified as Rodman Gravelly Loams and Strawn-Rodman complexes which occur predominantly along the outwash terraces of the Wabash River and its ...

We provide updated spatial distribution and inventory data for on-road NH3 emissions for the continental United States (U.S.) On-road NH3 emissions were determined from on-road CO2 emissions data and empirical NH3:CO2 vehicle emissions ratios. Emissions of NH3 from on-road sources in urbanized regions are typically 0.1– 1.3 t km−2 yr−1 while NH3 emissions in agricultural regions generally range from 0.4–5.5 t km−2 yr−1, with a few hot spots as high as 5.5–11.2 t km−2 yr−1. Counties with ...
A Comparison Of Two Methods Of Quantifying Mating Success In Low Density Gypsy Moth (Lymantria Dispar) Populations, 2018 Virginia Commonwealth University
A Comparison Of Two Methods Of Quantifying Mating Success In Low Density Gypsy Moth (Lymantria Dispar) Populations, Alexandra Barry, Hannah Byrne, Derek M. Johnson
Undergraduate Research Posters
The gypsy moth (Lymantria dispar) is a defoliating pest native to Europe and invasive to North America. The gypsy moth is subject to depressed mating success in low density populations, which may restrict spread of the forest pest. Research focusing on gypsy moth density as it relates to mating behavior has often used counts of males caught in pheromone-baited delta traps as a proxy to estimate the probability of female mating success. The purpose of this project was to determine whether pheromone trap counts provide accurate estimates of female mating success probability, by comparing data gathered from pheromone-baited delta traps ...
Efficacy Of Herbivore Exclusion On Planted Tree Seedling Vitality On A Reclaimed Surface Mine In Eastern Kentucky, 2018 University of Kentucky
Efficacy Of Herbivore Exclusion On Planted Tree Seedling Vitality On A Reclaimed Surface Mine In Eastern Kentucky, Zachary J. Hackworth
Theses and Dissertations--Forestry and Natural Resources
Conventional Appalachian surface-mine reclamation techniques repress natural forest regeneration, and tree plantings are often necessary for reforestation. Reclaimed Appalachian surface mines harbor a suite of mammal herbivores that forage on recently planted seedlings. Anecdotal reports across Appalachia have implicated herbivory in the hindrance and failure of reforestation efforts, yet empirical evaluation of herbivory impacts on planted seedling vitality in this region remains relatively uninitiated. First growing-season survival, height growth, and mammal herbivory damage of black locust (Robinia pseudoacacia L.), shortleaf pine (Pinus echinata Mill.), and white oak (Quercus alba L.) are presented in response to varying intensities of herbivore exclusion ...
Ecological-Economic Assessment Of The Effects Of Freshwater Flow In The Florida Everglades On Recreational Fisheries, 2018 Florida International University

USDA Forest Service / UNL Faculty Publications
This research develops an integrated methodology to determine the economic value to anglers of recreational fishery ecosystem services in Everglades National Park that could result from different water management scenarios. The study first used bio-hydrological models to link managed freshwater inflows to indicators of fishery productivity and ecosystem health, then link those models to anglers' willingness-to-pay for various attributes of the recreational fishing experience and monthly fishing effort. This approach allowed us to estimate the foregone economic benefits of failing to meet monthly freshwater delivery targets. The study found that the managed freshwater delivery to the Park had declined substantially ...
Tracking A Tree-Killer: Improving Detection And Characterizing Species Distribution Of Phytophthora Cinnamomi In Appalachian Forests, Kenton L. Sena
Theses and Dissertations--Plant and Soil Sciences
Phytophthora cinnamomi is a soil-borne oomycete pathogen causing root rot in susceptible host species. P. cinnamomi is thought to have originated in Southeast Asia, but has since been introduced to many regions around the world, where it causes dramatic declines in many forest tree species. In the eastern US, the primary susceptible tree species of concern are American chestnut (Castanea dentata), white oak (Quercus alba), and shortleaf pine (Pinus echinata). American chestnut, functionally eliminated in the early 1900s by the rapidly acting chestnut blight (Cryphonectria parasitica), has been the subject of decades-long breeding efforts aimed at improving chestnut resistance to ...
Resource Selection Of Free-Ranging Horses Influenced By Fire In Northern Canada, 2018 Oklahoma State University/Shifting Mosaics Consulting
Resource Selection Of Free-Ranging Horses Influenced By Fire In Northern Canada, Sonja E. R. Leverkus, Samuel D. Fuhlendorf, Marten Geertsema, Brady W. Allred, Mark Gregory, Alexandre R. Bevington, David M. Engle, J. Derek Scasta
Free-ranging or feral horses (Equus ferus caballus) were important to the livelihood of First Nations and indigenous communities in Canada. The early inhabitants of the boreal region of British Columbia (BC) capitalized on naturally occurring wildfires and anthropogenic burning to provide forage for free-ranging horses and manage habitat for wildlife. This form of pyric herbivory, or grazing driven by fi re via the attraction to the palatable vegetation in recently burned areas, is an evolutionary disturbance process that occurs globally. However, its application to manage forage availability for free-ranging horses has not been studied in northern Canada. Across Canada, there ...
Persistence Of Stream Restoration With Large Wood, Redwood National And State Parks, California, 2018 Humboldt State University
Persistence Of Stream Restoration With Large Wood, Redwood National And State Parks, California, Diedra L. Rodriguez
Theses and projects
The conservation and recovery of anadromous salmonids (Oncorhynchus sp.) depend on stream restoration and protection of freshwater habitats. In-stream large wood dictates channel morphology, increases retention of terrestrial inputs such as organic matter, nutrients and sediment, and enhances the quality of fish habitat. Historic land use/land cover changes have resulted in aquatic systems devoid of large wood. Restoration by placement of large wood jams is intended to restore physical and biological processes. An important question for scientists and restoration managers, in addition to the initial effectiveness of restoration, is the persistence and fate of large wood installations. In this ...
Impacts On Soils And Residual Trees From Cut-To-Length Thinning Operations In California's Redwood Forests, 2018 Humboldt State University
Impacts On Soils And Residual Trees From Cut-To-Length Thinning Operations In California's Redwood Forests, Kyungrok Hwang
Theses and projects
In northern California, a cut-to-length (CTL) system was used for the first time to harvest young redwood forests (Sequoia sempervirens (Lamb. ex D. Don) Endl.). However, landowners and public agencies are concerned about the potential negative impacts of CTL logging to soils and residual trees since the extent and amount of CTL impacts are unknown in these forests. This study was designed to (1) determine soil physical property using bulk density (BD) and hydraulic conductivity (HC) (2) examine the characteristics of stand damage after CTL harvesting, and (3) compare the scar size differences between tree growing patterns (individuals vs. clumps ...
Field Measures Of Wilderness Character For Bitterroot Recommended Wilderness, Bitterroot National Forest., 2018 The University Of Montana
Field Measures Of Wilderness Character For Bitterroot Recommended Wilderness, Bitterroot National Forest., Carly Stinson
Undergraduate Theses and Professional Papers
In order to know whether an area should become Wilderness, both managers and interested members of the public need to have an idea of what this area is like. My coworker Jamie Drysdale and I collected this data over nine weeks last summer. We followed protocols laid out in Keeping it Wild: An Interagency Strategy to Monitor Trends in Wilderness Character Across the Wilderness Preservation System. We collected data on things such as campsites, invasive plants, installations and developments, trail users, motorized or mechanized use, erosion, and signage. From this data I created maps of the different areas showing each ...
Landscape Host Abundance And Configuration Regulate Periodic Outbreak Behavior In Spruce Budworm (Choristoneura Fumiferana Clem.), Louis-Etienne Robert, Brian R. Sturtevant, Barry J. Cooke, Patrick M. A. James, Marie-Josee Fortin, Philip A. Townsend, Peter T. Wolter, Daniel Kneeshaw
Landscape-level forest management has long been hypothesized to affect forest insect outbreak dynamics, but empirical evidence remains elusive. We hypothesized that the combination of increased hardwood relative to host tree species, prevalence of younger forests, and fragmentation of those forests due to forest harvesting legacies would reduce outbreak intensity, increase outbreak frequency, and decrease spatial synchrony in spruce budworm (Choristoneura fumiferana Clem.) outbreaks. We investigated these hypotheses using tree ring samples collected across 51 sites pooled into 16 subareas distributed across a large ecoregion spanning the international border between Ontario (Canada), and Minnesota (USA). This ecoregion contains contrasting land management ...
