The economic contributions of agricultural production and processing …


Las Raíces De La Deforestación En El Departamento Pando, Jeremy Levine-Drizin Oct 2013

Las Raíces De La Deforestación En El Departamento Pando, Jeremy Levine-Drizin

Independent Study Project (ISP) Collection

This research paper examines the phenomenon of the recent trend of deforestation in the Pando department in northwestern Bolivia. Historically, the economy of Pando has always been based primarily in agro-forestal extraction activities that provided income to communities without the need to destroy the surrounding forests. The most important of these agro-forestal products have been rubber (primarily during the beginning of the 20th century) and more recently Castaña (Brazilian Nut). Recently however, as the result of various forces, the inhabitants of Pando have begun to cut down there forests at an alarming rate. The most relevant causes of this phenomenon …

Job Growth And Loss Across Sectors And Time In The Western Us: The Impact Of Large Wildfires, Max Nielsen-Pincus, Cassandra Moseley, Krista Gebert Sep 2013

Job Growth And Loss Across Sectors And Time In The Western Us: The Impact Of Large Wildfires, Max Nielsen-Pincus, Cassandra Moseley, Krista Gebert

Environmental Science and Management Faculty Publications and Presentations

The link between economic growth and natural hazards has long been studied to better understand the effects of natural hazards on local, regional, and country level growth patterns. However, relatively little generalizable research has focused on wildfires, one of the most common forest disturbances in the western United States (US). We examined the effect of large wildfires on employment growth across sectors and time in the western US.We matched wildfire occurrences from 2004 to 2008 and their duration with monthly employment data to identify the effect of wildfire on employment growth. Wildfires generally tended to exhibit positive effects on employment …


Climate Change And North American Rangelands: Assessment Of Mitigation And Adaptation Strategies, Linda A. Joyce, David D. Briske, Joel R. Brown, H. Wayne Polley, Bruce A. Mccarl, Derek W. Bailey Sep 2013

Climate Change And North American Rangelands: Assessment Of Mitigation And Adaptation Strategies, Linda A. Joyce, David D. Briske, Joel R. Brown, H. Wayne Polley, Bruce A. Mccarl, Derek W. Bailey

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Recent climatic trends and climate model projections indicate that climate change will modify rangeland ecosystem functions and the services and livelihoods that they provision. Recent history has demonstrated that climatic variability has a strong influence on both ecological and social components of rangeland systems and that these systems possess substantial capacity to adapt to climatic variability. Specific objectives of this synthesis are to: 1) evaluate options to mitigate greenhouse gas emissions and future climate change; 2) survey actions that individuals, enterprises, and social organizations can use to adapt to climate change; and 3) assess options for system transformation when adaptation …

Dendrochronological Reconstruction Of Fire, Bogus Basin Area Boise National Forest, Amy L. Cutter Aug 2013

Dendrochronological Reconstruction Of Fire, Bogus Basin Area Boise National Forest, Amy L. Cutter

Student Research Initiative

Since people have settled along the Boise Front, there have been very few documented fire disturbances. This is likely an outcome of fire suppression policies. There is evidence, visible as scars on living trees, that the old growth ponderosa pines located on the East Side Trail in the Boise National Forest have withstood multiple fires. Samples were collected by using a chainsaw to remove small, partial cross-sections from several trees. The Boise Front master chronology was used to accurately cross-date the fire-scarred samples using COFECHA. Analysis of the samples revealed ten fire events ranging from 1709 to 1889. The fire …


Capturing Fire: Rxcadre Takes Fire Measurements To Whole New Level, Gail Wells Aug 2013

Capturing Fire: Rxcadre Takes Fire Measurements To Whole New Level, Gail Wells

Joint Fire Science Program Digests

Models of fire behavior and effects do not always make accurate predictions, and there is not enough systematically gathered data to validate them. To help advance fire behavior and fire effects model development, the Joint Fire Science Program is helping fund the RxCADRE, which is made up of scientists from the U.S. Forest Service and several universities who orchestrate and collect data on prescribed burns in the southeastern United States. The RxCADRE-prescribed burns are yielding a comprehensive dataset of fire behavior, fire effects, and smoke chemistry and dynamics, with measurements taken systematically at multiple, cascading scales. RxCADRE data will help …

Understanding Relationships Among Abundance, Extirpation, And Climate At Ecoregional Scales, Erik A. Beever, Solomon Z. Dobrowski, J. Long, A. R. Mynsberge, N. B. Piekielek Jul 2013

Understanding Relationships Among Abundance, Extirpation, And Climate At Ecoregional Scales, Erik A. Beever, Solomon Z. Dobrowski, J. Long, A. R. Mynsberge, N. B. Piekielek

Forest Management Faculty Publications

Recent research on mountain-dwelling species has illustrated changes in species' distributional patterns in response to climate change. Abundance of a species will likely provide an earlier warning indicator of change than will occupancy, yet relationships between abundance and climatic factors have received less attention. We tested whether predictors of counts of American pikas (Ochotona princeps) during surveys from the Great Basin region in 1994-1999 and 2003-2008 differed between the two periods. Additionally, we tested whether various modeled aspects of ecohydrology better predicted relative density than did average annual precipitation, and whether risk of site-wide extirpation predicted subsequent population counts of …

Preserving Nature Through Film: Wilderness Alps Of Stehekin And The North Cascades, 1956-1968, Nicolas Timothy Bergmann Jun 2013

Preserving Nature Through Film: Wilderness Alps Of Stehekin And The North Cascades, 1956-1968, Nicolas Timothy Bergmann

Dissertations and Theses

On March 22, 1958 David Brower's film Wilderness Alps of Stehekin premiered to an audience of conservationists in Seattle, Washington. Almost two years in the making, the thirty-one minute film advocated the preservation of nature in Washington's North Cascades through the creation of a national park. Over the next decade, Wilderness Alps of Stehekin became the most influential publicity tool in the struggle to preserve the North Cascades. Because of the region's geographic isolation, the film was the first time many people throughout the nation were exposed to the scenic grandeur of the area. Images of craggy peaks and colorful …

Fuel Treatments And Fire Severity: A Meta-Analysis, Erik J. Martinson, Philip N. Omi Jun 2013

Fuel Treatments And Fire Severity: A Meta-Analysis, Erik J. Martinson, Philip N. Omi

Joint Fire Science Program Synthesis Reports

We employed meta-analysis and information theory to synthesize findings reported in the literature on the effects of fuel treatments on subsequent fire intensity and severity. Data were compiled from 19 publications that reported observed fire responses from 62 treated versus untreated contrasts. Effect sizes varied widely and the most informative grouping of studies distinguished three vegetation types and three types of fuel treatment. The resultant meta-analytic model is highly significant (p < 0.001) and explains 78% of the variability in reported observations of fuel treatment effectiveness. Our synthesis highlights several considerations that both support and inform the current fuels management paradigm.


Variability In Soil Climate And Respiration On Managed Timber Stands: A Case Study In Southwest Oregon, Scott Pensky, Adrian Gallo Jun 2013

Variability In Soil Climate And Respiration On Managed Timber Stands: A Case Study In Southwest Oregon, Scott Pensky, Adrian Gallo

Natural Resources Management and Environmental Sciences

Thinning of forested lands and timber stands in the Pacific Northwest have taken place for centuries with a limited understanding of how the alterations may affect ecosystem functions. The goal of this study was to examine the soil climate and microbial activity on a seasonal timescale of thinning practices examined at different stages of succession. Two timber stands in Southwestern Oregon within the Grayback Creek Watershed were chosen because of identical forest management techniques separated by a 10-year treatment interval (40% variable density thinning). Field methods and equipment measured canopy coverage, soil moisture and temperature at 3 depths (5, 15, …

Climate Change Tipping Points: A Point Of No Return?, Elise Lequire May 2013

Climate Change Tipping Points: A Point Of No Return?, Elise Lequire

Joint Fire Science Program Digests

Summer 2012 saw records fall for intensity of drought and number, size, and cost of wildfires in the Central and Western United States, and the climate forecast calls for more of the same in the near and distant future. When wildfire breaks out, emergency responders decide their immediate strategy based on past experience and quick judgment calls. But in the long term, land managers need to plan for a warmer climate on a time scale of decades, or even a century or more, to better reflect the life span of trees and forests. Studies supported by the Joint Fire Science …


Response Of Breeding Birds To Forest Disturbance In The Arkansas Ozarks: Impacts Of Uneven-Aged Management, Ice Damage, And Woodland Restoration, Maureen Mcclung May 2013

Response Of Breeding Birds To Forest Disturbance In The Arkansas Ozarks: Impacts Of Uneven-Aged Management, Ice Damage, And Woodland Restoration, Maureen Mcclung

Graduate Theses and Dissertations

Forests of the Ozarks are important breeding grounds for many bird species, each with specific habitat requirements. Natural and anthropogenic disturbance events can alter vegetational structure of forests, thereby influencing communities of breeding birds. The objectives of my study were to examine the response of breeding birds and their habitat to three types of forest disturbance: (1) uneven-aged management, (2) ice damage, and (3) woodland restoration. Avian and vegetation surveys were conducted during the 2008, 2009, and 2010 breeding seasons (May-June) in the Ozark National Forest, Arkansas. Each site was surveyed for birds four times a season using fixed-radius point …
