Bark Beetle-Induced Changes To Crown Fuel Flammability And Crown Fire Potential, Wesley G. Page May 2014

Bark Beetle-Induced Changes To Crown Fuel Flammability And Crown Fire Potential, Wesley G. Page

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Recent outbreaks of aggressive tree-killing bark beetles, including mountain pine beetle in lodgepole pine forests and spruce beetle in Engelmann spruce forests, have recently affected vast areas across western North America. The high levels of tree mortality associated with these outbreaks have raised concerns amongst fire managers and wildland firefighters about the possible effects on fire behavior potential, particularly crown fire potential, as crown fires (fires that consume part or all of tree crowns) hinder the ability of firefighters to conduct safe and effective fire suppression operations. The purpose of this research was to measure and characterize the changes in …

"Nature Is Pushing One Way And People Are Pushing The Other": A Political Ecology Of Forest Transitions In Western Montgomery County, Pa, Megan Elizabeth Maccaroni Apr 2014

"Nature Is Pushing One Way And People Are Pushing The Other": A Political Ecology Of Forest Transitions In Western Montgomery County, Pa, Megan Elizabeth Maccaroni

Environment and Sustainability Honors Papers

Forests in Southeastern Pennsylvania have been shaped by a number of anthropocentric factors over the past century, with many areas experiencing a recent trend towards forest recovery. Studies on forest dynamics have shown that most developed regions exhibit a forest transition, which begins when land is cleared for natural resource extraction (e.g., agriculture, forestry) during an early development stage. Then as a population grows and food production needs are met, rural peoples begin to migrate to the city, and a feeling of scarcity of trees develops that may lead to changes in land management attitudes, and many formerly deforested areas …

Effect Of Australian Pine (Casuarina Equisetifolia) Canopy Density On The Understory Plant Community On San Salvador, Bahamas, Jeffry Anderson, Anna Baumgartner Apr 2014

Effect Of Australian Pine (Casuarina Equisetifolia) Canopy Density On The Understory Plant Community On San Salvador, Bahamas, Jeffry Anderson, Anna Baumgartner

Celebrating Scholarship & Creativity Day (2011-2017)

Casuarina equisetifolia, or Australian pine, is an invasive angiosperm species on the island of San Salvador, The Bahamas. It was originally found only in Southeast Asia and Australia. This tree is unique in that its leaves are much reduced and occur in whorls around the photosynthetic branchlets. It has been established that this tree contributes to the increased erosion of sediment on the dunes of San Salvador (Sealey 1998). This study investigated several possible factors contributing to differences in the understory plant community which may contribute to this erosion including leaf litter density, shading, and soil pH. It is …

Advances in forest carbon mapping have the potential to greatly reduce uncertainties in the global carbon budget and to facilitate effective emissions mitigation strategies such as REDD+. Though broad scale mapping is based primarily on remote sensing data, the accuracy of resulting forest carbon stock estimates depends critically on the quality of field measurements and calibration procedures. The mismatch in spatial scales between field inventory plots and larger pixels of current and planned remote sensing products for forest biomass mapping is of particular concern, as it has the potential to introduce errors, especially if forest biomass shows strong local spatial …

Water For Electricity In The Upper Savannah Basin: Impacts On Freshwater Mussels, Alan Johnson, Snehal Mhatre Apr 2014

Water For Electricity In The Upper Savannah Basin: Impacts On Freshwater Mussels, Alan Johnson, Snehal Mhatre

Graduate Research and Discovery Symposium (GRADS)

The water resources of the Upper Savannah River Basin are subjected to extensive water withdrawals for production of electricity for the region. The use of Savannah River Basin water resources for electricity production and the associated impact on reservoir levels, streamflows, and thermal regimes is in conflict with the requirements of in-stream biota particularly freshwater mussels. The Savannah River Basin contains atleast 26 unionid species, most of which are listed as endangered, threatened, or of special concern at the state level. Populations of these species have experienced significant declines and extirpations in the recent decades. Of these unionid species, brook …

Plant Community Structure Over An Elevation Gradient In Manongarivo Special Reserve, Madagascar, Scott Sugden Apr 2014

Plant Community Structure Over An Elevation Gradient In Manongarivo Special Reserve, Madagascar, Scott Sugden

Independent Study Project (ISP) Collection

This study examines how plant community structure changes across an elevation gradient in Manongarivo Special Reserve, Madagascar. Three vegetation surveys were conducted at each of six different elevations (300m, 500m, 700m, 850m, 1000m, 1150m) on the southern slope of Bekolosy Mountain, near the southwestern border of the reserve. Each of these surveys focused on the diameter, height, and crown position of trees in a 156.25m2 plot, as well as the presence or absence of mosses and vines. At each of the six survey elevations, point-quadrat vertical structure data was also collected for the underbrush, up to a maximum height of …

The Effectiveness Of Forest Collaborative Groups At Reducing The Likelihood Of Project Appeals And Objections In Eastern Oregon, Brent M. Summers Apr 2014

The Effectiveness Of Forest Collaborative Groups At Reducing The Likelihood Of Project Appeals And Objections In Eastern Oregon, Brent M. Summers

Environmental Science and Management Professional Master's Project Reports

Collaborative planning has been used as a tool to address wicked natural resource conflicts and engage those affected by federal land management agency decisions. The United States Forest Service (USFS) is mandated by law to involve the public on project-level planning. In Oregon, Forest Collaborative Groups have been engaging with the USFS to involve stakeholders who are concerned with the activities on National Forests. It is widely believed that these groups are reducing project-level appeals and objections (appeals); however, there is no empirical evidence to validate these beliefs. National Environmental Protect Act (NEPA) document data were collected from the USFS …

Naturalized Offspring From An 85-Year-Old Chinese Chestnut (Castanea Mollissima) Planting: Stand Dynamics And Genetic Relationships, Amy Christel Miller

Open Access Theses

Chestnuts, members of the genus Castanea , family Fagaceae, are valuable worldwide, and all species have noteworthy ecological, economic, and cultural importance in their native ranges. Historically, American chestnut (Castanea dentata (Marshall) Borkh.) was an abundant tree species in eastern North America until its decimation in the early 20 th century by chestnut blight, caused by the fungus Cryphonectria parasitica . To regain the benefits of this prized species in North America, efforts are ongoing to produce and introduce blight-resistant hybrids of C. dentata and the blight-resistant Chinese chestnut ( C. mollissima Blume). It is important that the C. …

Ecological Interactions Affecting American Chestnut Restoration And Allegheny Woodrat Conservation In Indiana, Rita Michelle Blythe Apr 2014

Ecological Interactions Affecting American Chestnut Restoration And Allegheny Woodrat Conservation In Indiana, Rita Michelle Blythe

Open Access Theses

The Allegheny woodrat (Neotoma magister ) is a small rodent native to rocky habitats surrounded by deciduous forests in the eastern United States. Woodrats have recently experienced a severe range-wide decline and are a species of conservation concern throughout their range. In Indiana, the persistence of woodrat populations is threatened by a loss of genetic diversity, so captive propagation was initiated to ameliorate the immediate threat of inbreeding depression and improve local genetic diversity. However, achieving the objectives of captive propagation ultimately depends on the ability of captive-reared individuals to survive in the wild until they can contribute reproductively …

Trail Degradation In Parque Internacional La Amistad: An Intersection Of Design, Management And Use, Jordan Stark Apr 2014

Trail Degradation In Parque Internacional La Amistad: An Intersection Of Design, Management And Use, Jordan Stark

Independent Study Project (ISP) Collection

National parks are created and used for a variety of purposes but are primarily important for the conservation of natural resources and use by visitors. While park use is meant to be non-destructive, human interaction causes changes in ecosystems, leading to conflicts between these goals. Here, I examine the causes of trail degradation and impacts on surrounding forests in Parque Internacional la Amistad (PILA), Panama. This park is a world heritage site with the primary goal of preserving some of the world’s most diverse ecosystems including rare and endangered species. However, the park entrance in Las Nubes, Cerro Punta receives …

Consequences Of A Refuge For The Predator-Prey Dynamics Of A Wolf-Elk System In Banff National Park, Alberta, Canada, Joshua F. Goldberg, Mark Hebblewhite, Jonathan M. Bardsley Mar 2014

Consequences Of A Refuge For The Predator-Prey Dynamics Of A Wolf-Elk System In Banff National Park, Alberta, Canada, Joshua F. Goldberg, Mark Hebblewhite, Jonathan M. Bardsley

Wildlife Biology Faculty Publications

Refugia can affect predator-prey dynamics via movements between refuge and non-refuge areas. We examine the influence of a refuge on population dynamics in a large mammal predator-prey system. Wolves (Canis lupus) have recolonized much of their former range in North America, and as a result, ungulate prey have exploited refugia to reduce predation risk with unknown impacts on wolf-prey dynamics. We examined the influence of a refuge on elk (Cervus elaphus) and wolf population dynamics in Banff National Park. Elk occupy the Banff townsite with little predation, whereas elk in the adjoining Bow Valley experience higher wolf predation. The Banff …
