Soil Succession: Short And Long-Term Impacts Of Grazing On Soil Properties In A Tropical Montane Cloud Forest, June Curtis

Independent Study Project (ISP) Collection

Cattle ranching is the leading cause of deforestation in South America, causing long-lasting alterations to the continent's landscape and ecology. Tropical montane cloud forests (TMCFs) are a rare ecosystem particularly vulnerable to the effects of land conversion to pasture, a process which has implications ranging from biodiversity loss to soil degradation. Grazing is known to significantly alter soils' physical structure through processes of compaction and erosion as well as significant additions of organic matter. Silvopasture, or the integration of pasture and forest, has emerged as an alternative to traditional grazing practices with the hope of mitigating environmental and soil degradation. …

Agroforestry For The Future: Motivations Behind Tasmanian Farmers Planting Trees, Josh Lipp

Independent Study Project (ISP) Collection

Agroforestry is the act of combining farming and tree planting, and many Tasmanian farmers are starting to plant trees on their properties for multiple reasons. Through conducting 9 interviews with farmers and researchers and visiting field sites, 3 main themes were identified to answer the question: why are Tasmanian farmers planting trees, and what are the benefits and downsides to agroforestry? Interviews help us understand farmers’ perceptions of agroforestry, and field data collection will prove the benefits of agroforestry in the future. Tasmania was chosen as the location of study as it is a state in Australia that largely focuses …

What’S At “Steak”: The Drivers Of Deforestation In The Brazilian Amazon And Potential Multilateral Solutions, Soleil Gaylord

Independent Study Project (ISP) Collection

This paper examines the contemporary drivers of deforestation in the Brazilian Legal Amazon and how multilateral solutions can be employed to bring forest loss to zero. Insights from the scholarly literature and five expert interviews allow a critical assessment of how the rise of unilateralism presents a novel threat to the Brazilian Legal Amazon and, by proxy, those relying on the region’s raw resources and ecosystem services. Integrating analyses of both Brazilian institutional structures and global environmental governance frameworks, this study examines the primary historical and contemporary factors driving accelerated deforestation rates observed under Brazil’s President Jair Bolsonaro. In identifying …

Disturbance Reduces Fungal White-Rot Litter Mat Cover In A Wet Subtropical Forest, D. Jean Lodge, Ashley E. Van Beusekom, Grizelle González, Mareli Sánchez-Julia, Sarah Stankavich

USDA Forest Service / UNL Faculty Publications

Fungi that bind leaf litter into mats and produce white-rot via degradation of lignin and other aromatic compounds influence forest nutrient cycling and soil fertility. Extent of white-rot litter mats formed by basidiomycete fungi in Puerto Rico decreased in response to disturbances—a simulated hurricane treatment executed by canopy trimming and debris addition in 2014, a drought in 2015, a treefall, and two hurricanes 10 days apart in September 2017. Percent fungal litter mat cover ranged from 0.4% after Hurricanes Irma and Maria to a high of 53% in forest with undisturbed canopy prior to the 2017 hurricanes, with means mostly …

Picking Up Where The Tmdl Leaves Off: Using The Partnership Wild And Scenic River Framework For Collaborative River Restoration, Alan R. Hunt, Meiyin Wu, Tsung-Ta David Hsu, Nancy Roberts-Lawler, Jessica T. Miller, Alessandra Rossi, Lee Lee

Department of Biology Faculty Scholarship and Creative Works

The National Wild and Scenic Rivers Act protects less than ¼ of a percent of the United States’ river miles, focusing on free-flowing rivers of good water quality with outstandingly remarkable values for recreation, scenery, and other unique river attributes. It predates the enactment of the Clean Water Act, yet includes a clear anti-degradation principle, that pollution should be reduced and eliminated on designated rivers, in cooperation with the federal Environmental Protection Agency and state pollution control agencies. However, the federal Clean Water Act lacks a clear management framework for implementing restoration activities to reduce non-point source pollution, of which …

Lepidopteran Diversity And Abundance Across Five Different Indigenously Managed Land Use Zones In The Naso-Teribe Territory, Bocas Del Toro Province, Panama, Eli Dotson

Independent Study Project (ISP) Collection

Lepidopterans, the order that includes both moths and butterflies, are among the best-known insects taxonomically and ecologically due to the relative ease of monitoring them in comparison to other groups of insects. Their distribution follows that of other insects and forms of life, as around 90% of species have a tropical distribution. This incredibly speciose group of animals fills many vital roles in the ecosystems they inhabit, including herbivores in their larval stages, prey for a variety of predators in all life stages, and pollinators for many plant species as adults. In some circumstances, certain species may also serve as …

Kentucky Forestry Economic Contribution Report 2016, Jeff Stringer, Billy Thomas, Bobby Ammerman, Thomas Ochuodho, Alison Davis

Kentucky Forestry Economic Impact Reports

Forests play a pivotal role in Kentucky’s economy and in the lives of the citizens of our state. Forests are the single most dominant land type, covering nearly one-half of the state, providing a significant range of both economic and non-economic benefits to the Commonwealth. The majority of the economic contribution is derived from the harvesting of timber and processing of the wood resource. Analysis of Kentucky’s forest and wood industries in 2016 indicated an estimated direct economic contribution of $9 billion (down one percent from 2015). These industries employed over 27,700 individuals. Total economic contributions in 2016 were estimated …

Assisted Tree Migration In North America: Policy Legacies, Enhanced Forest Policy Integration, And Climate Change Adaptation, Adam Wellstead, Michael Howlett

Department of Social Sciences Publications

The weight of much expert forest management opinion is that issues such as climate change can be effectively addressed only if forest policy-making moves from a purely sectoral focus and undergoes a shift to a more integrated multi-issue, multi-sector policy-making process. This is because credible adaptation policies in the sector require greatly enhanced multi-sectoral policy integration if they are to succeed. But this requirement may be beyond the capacity of many countries to deliver. This article explores the integration challenges faced by forest policy-making in Canada and the United States and uses the case of Assisted Tree Migration (ATM) to …

Alternative Timing Of Carbaryl Treatments For Protecting Lodgepole Pine From Mortality Attributed To Mountain Pine Beetle, Christopher J. Fettig, A Steve Munson, Kenneth E. Gibson

USDA Forest Service / UNL Faculty Publications

Carbaryl is regarded among the most effective, economically viable, and ecologically-compatible insecticides available for protecting conifers from bark beetle attack in the western United States. Treatments are typically applied in spring prior to initiation of bark beetle flight for that year. We evaluated the efficacy of spring and fall applications for protecting individual lodgepole pine, Pinus contorta Dougl. ex Loud, from mortality attributed to mountain pine beetle, Dendroctonus ponderosae Hopkins, the most notable forest insect pest in western North America. Both spring and fall treatments of 2.0% a.i. carbaryl (Sevin® SL) were efficacious for two field seasons, while results from …

Fairmount Greenway - A Community Initative, Leah H. Bamberger, Liliana Carvajal, Mary F. Dehais, Yuanfang Gong, John E. Hulsey, Eric C. Kells, Kimberley Klosterman, Pamela Jo Landi, Adam G. Monroy, Seth A. Morrow, Bryan O'Bara, Jie Su, Arianna Thompson, Owen M. White

Landscape Architecture & Regional Planning Studio and Student Research and Creative Activity

This studio was based on the Fairmount Greenway that was developed through a series of public meetings with the neighborhood community and with consultants from the firm Crosby, Schlessinger and Smallridge (CSS). The Fairmount Greenway, while drawing its identity from the traditional greenway model is in fact a reinterpretation of an urban greenway. The greenway path follows along both primary and secondary city streets because of the lack of space along the rail right-of-way. The Fairmount Greenway begins at what will be a new station stop at New Market South Bay near Upham’s Corner in northern Dorchester. The greenway follows …

Blanding’S Turtle (Emydoidea Blandingii): A Technical Conservation Assessment, Justin D. Congdon, Douglas A. Keinath

USDA Forest Service / UNL Faculty Publications

Blanding’s turtles (Emydoidea blandingii) are secure in Nebraska, and they range from being vulnerable to threatened, or endangered throughout most of the rest of their distribution. In Region 2, they have not been reported from Kansas, they are extremely rare in South Dakota, and they occupy wetlands in the northern half of Nebraska. The largest population known within the range of Blanding’s turtles is at Valentine National Wildlife Refuge, Nebraska.

The core habitat of Blanding’s turtles has an aquatic component that consists of a permanent wetland and a suite of other, usually smaller and more temporary, wetlands such …

Changing Maine, 1960-2010: Teaching Guide, Richard Barringer, New England Environmental Finance Center

Maine History & Policy Development

Unlike forty years ago, none of us is now certain what the future holds for Maine – except that it will be different. Maine has been transformed by the events of the recent decades. We have come into a new world, a new time – a new historical era, if you will. This new era, like previous eras in Maine history, will require of us new ways of thinking, new ways of understanding, new ways of organizing ourselves as a community of people, if the values and culture we share and cherish are to endure and flourish.

Licuala Palms In Brunei Dusun Ethnobotany, Jay H. Bernstein, Roy F. Ellen

Publications and Research

Several species of Licuala occur in the Merimbun area of Tutong district, Brunei Darussalam. One kind of Licuala, called benjiru by the local Dusun population, is often collected for sale as a vegetable. While Licuala is not generally considered an important economic plant, overharvesting in the Merimbun area suggests that conservation measures may be needed to protect it from local extinction. Besides benjiru, other kinds of Licuala recognized by the Dusun are called silad and ukang. The three kinds of Licuala do not have one overall name in the Dusun language, but constitute a covert category at the "intermediate" ethnobotanical …
