The intensive 6-week instruction includes teaching how to use the Global Positioning System (GPS) to accurately record the true spatial location of an earth’s surface feature. After receiving hands-on instructions during the summer of 2013, students were taken to the field to …
Economic Contribution Of Agriculture And Food To Arkansas' Gross Domestic Product 1997-2011, Jacob Manlove, Leah English, Jennie Popp, Wayne Miller
Economic Contribution Of Agriculture And Food To Arkansas' Gross Domestic Product 1997-2011, Jacob Manlove, Leah English, Jennie Popp, Wayne Miller
AAES Research Reports and Research Bulletins
Agricultural production, processing, and retail industries are major contributors to the Arkansas economy in terms of GDP. Agriculture contributes to the economy through direct agricultural production, value-added processing, and agricultural retail activities, and it also plays an important role through its interactions with other sectors. The use of non-agricultural goods and services as inputs into the agricultural sector promotes diversified growth in Arkansas’ economy; thus agriculture remains a vital part of Arkansas’ economy. Part 1 of the report compares the relative size of the Agriculture and Food Sector in Arkansas with those of neighboring states, the Southeastern region of the …
Wire Netting Reduces African Elephant (Loxodonta Africana) Impact To Selected Large Trees In South Africa, Kelly Derham
Wire Netting Reduces African Elephant (Loxodonta Africana) Impact To Selected Large Trees In South Africa, Kelly Derham
Masters Theses & Specialist Projects
African elephants (Loxodonta africana) are ecosystem engineers in that they substantially alter the environment through their unique foraging and feeding habits. At high densities, elephants potentially have negative impacts on the environment, specifically to large trees. Because of this, recent increases of elephants in the Associated Private Nature Reserves (APNR) on the Western Boundary of Kruger National Park, South Africa have caused concern regarding the health of several species of tree. My objective was to assess the effectiveness of wrapping protective wire netting around the trunk of the tree in preventing and reducing bark stripping by elephants. 2,668 …

"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 …

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 …

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

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 …

Climate Change Effects On Northern Great Lake (Usa) Forests: A Case For Preserving Diversity, Matthew Joshua Duveneck, Robert M. Scheller, Mark A. White, Stephen D. Handler, Catherine Ravenscroft
Environmental Science and Management Faculty Publications and Presentations
Under business as usual (BAU) management, stresses posed by climate change may exceed the ability of Great Lake forests to adapt. Temperature and precipitation projections in the Great Lakes region are expected to change forest tree species composition and productivity. It is unknown how a change in productivity and/or tree species diversity due to climate change will affect the relationship between diversity and productivity. We assessed how forests in two landscapes (i.e., northern lower Michigan and northeastern Minnesota, USA) would respond to climate change and explored the diversityproductivity relationship under climate change. In addition, we explored how tree species diversity …

Anthropology Publications
The most threatened mammal group on Earth, Madagascar’s five endemic lemur families (lemurs are found nowhere else), represent more than 20% of the world’s primate species and 30% of family-level diversity. This combination of diversity and uniqueness is unmatched by any other country—remarkable considering that Madagascar is only 1.3 to 2.9% the size of the Neotropics, Africa, or Asia, the other three landmasses where nonhuman primates occur. But lemurs face extinction risks driven by human disturbance of forest habitats. We discuss these challenges and reasons for hope in light of site-specific, local actions proposed in an emergency conservation action plan.

Structure And Composition Of Old-Growth And Unmanaged Second-Growth Riparian Forests At Redwood National Park, Usa, Christopher R. Keyes, Emily K. Teraoka
Forest Management Faculty Publications
Restoration of second-growth riparian stands has become an important issue for managers of redwood (Sequoia sempervirens [D. Don] Endl.) forest reserves. Identifying differences between old-growth and second-growth forest vegetation is a necessary step in evaluating restoration needs and targets. The objective of this study was to characterize and contrast vegetation structure and composition in old-growth and unmanaged second-growth riparian forests in adjacent, geomorphologically similar watersheds at Redwood National Park. In the old-growth, redwood was the dominant overstory species in terms of stem density, basal area, and importance values. Second-growth was dominated by red alder (Alnus rubra Bong.), …

Fuel Reduction Practices And Their Effects On Soil Quality, Matt D. Busse, Ken R. Hubbert, Emily E. Y. Moghaddas
Joint Fire Science Program Synthesis Reports
Soils sustain our terrestrial ecosystems, help fuel plant growth, and govern key ecosystem services such as the storage and provision of clean water, degradation of toxic compounds, and regulation of atmospheric gases. Preserving the integrity of soil thus is an earnest responsibility of land stewardship in the United States. This report provides a synthesis of soil chemical, biological, and physical responses to various prescribed fire and mechanical thinning practices and offers practical considerations for use in fuel reduction planning. A wide range of current topics, identified in a nationwide survey of natural resource managers, is discussed in detail: (1) ecological …

Management For Mountain Pine Beetle Outbreak Suppression: Does Relevant Science Support Current Policy?, Diana Six, Eric Biber, Elisabeth Long
Ecosystem and Conservation Sciences Faculty Publications
While the use of timber harvests is generally accepted as an effective approach to controlling bark beetles during outbreaks, in reality there has been a dearth of monitoring to assess outcomes, and failures are often not reported. Additionally, few studies have focused on how these treatments affect forest structure and function over the long term, or our forests’ ability to adapt to climate change. Despite this, there is a widespread belief in the policy arena that timber harvesting is an effective and necessary tool to address beetle infestations. That belief has led to numerous proposals for, and enactment of, significant …
