Importance Of Scale, Land Cover, And Weather On The Abundance Of Bird Species In A Managed Forest, Alexis R. Grinde, Gerald J. Niemi, Brian R. Sturtevant, Hannah Panci, Wayne Thogmartin, Peter Wolter

Natural Resource Ecology and Management Publications

Climate change and habitat loss are projected to be the two greatest drivers of biodiversity loss over the coming century. While public lands have the potential to increase regional resilience of bird populations to these threats, long-term data are necessary to document species responses to changes in climate and habitat to better understand population vulnerabilities. We used generalized linear mixed models to determine the importance of stand-level characteristics, multi-scale land cover, and annual weather factors to the abundance of 61 bird species over a 20-year time frame in Chippewa National Forest, Minnesota, USA. Of the 61 species modeled, we were ...

Reconstruction Of Piñon-Juniper Forest Structure To Examine Historic Wildlife Habitat Characteristics In The Davis Mountains, Usa, Brian P. Oswald, John R. Lanham, James C. Kroll, Mohammed M. Bataineh, Yanli Zhang

Faculty Publications

Changes in piñon-juniper (Pinus spp., Juniperus spp.) communities across the southwestern United States have often decreased ecological diversity of the understory and increases of exotic species. Reconstructing age and establishment patterns provides essential understanding to guide treatments and management for anthropogenically-altered forests. The goal of this study was to determine how patterns of piñon and juniper growth in the Davis Mountains, Texas, varied over time and how this pattern influenced wildlife habitat of several indicator species. Establishment patterns and basal area growth progression were identified, canopy cover estimates regressed from pre-developed canopy regression equations to re-construct historic forest stand structure ...


Evaluating The Influence Of Stem Form And Vigor On Product Potential, Growth, And Survival For Northern Commercial Hardwood Species, Mark Castle 2017 The University of Maine

Evaluating The Influence Of Stem Form And Vigor On Product Potential, Growth, And Survival For Northern Commercial Hardwood Species, Mark Castle

Electronic Theses and Dissertations

Northern hardwood and mixed-wood forest types occupy a considerable percentage of the forest landscape across the Northeastern United States and portions of eastern Canada. While capable of producing valuable saw timber and veneer products, hardwood species demonstrate a wide range of stem quality resulting from the large variety of stem forms and defects that these species can manifest. The effect of different stem forms and damage has largely not been accounted for in predictions of volume, growth, and mortality. In addition to potential bias in growth and yield applications, the lack of quantification of these features has left the efficacy ...


Comparison Of Understory Chemical And Mechanical Treatments To Promote Regeneration Of Desirable Forestland Species, Rebecca Rachael Tyler 2017 Missouri State University

Comparison Of Understory Chemical And Mechanical Treatments To Promote Regeneration Of Desirable Forestland Species, Rebecca Rachael Tyler

MSU Graduate Theses

Invasive woody plants and trees can have a negative impact on desired tree regeneration in the understory of forest stands, and forage density in grassland sites. An assessment of chemical and mechanical treatments on woody plants in the understory of forestland and in grassland is needed. Two experiments were set up in two forest stands and in two grassland/forest edge sites, with two treatment times during the growing season in the first year of the study. On the forestland sites, chemical and mechanical treatments were applied on undesired woody plants to see if they effect the regeneration of desired ...


The Impact Weather Has On Nyc Citi Bike Share Company Activity, Mark Martinez 2017 Colby College

The Impact Weather Has On Nyc Citi Bike Share Company Activity, Mark Martinez

Journal of Environmental and Resource Economics at Colby

This paper seeks to figure out the effect weather has on individuals’ behavior. A more focused approach to determining this effect is seeing how different weather conditions ranging from the temperature, the precipitation, the amount of inches of snowfall and the wind speed effect the ridership of Citi Bikes throughout all four seasons. The approach of this research paper is using data from the National Climatic Data Center that focuses in on the weather found in Manhattan, New York and correlates each of the weather conditions to the total number of trips per day that is provided by the Citi ...


The Effects From Public Transportation On Property Values: A Closer Look At Scituate, Hanover, And Norwell, Massachusetts, Alexandra Taylor Perticone, Christine S. Coveney 2017 Colby College

The Effects From Public Transportation On Property Values: A Closer Look At Scituate, Hanover, And Norwell, Massachusetts, Alexandra Taylor Perticone, Christine S. Coveney

Journal of Environmental and Resource Economics at Colby

Prior studies have expressed the value of location in real estate, but more recent studies have explored the influence that public transportation has had on housing prices. Access to public transportation is understood to increase the value of homes. Easier access to public transportation allows for shorter and more convenient commutes into or within cities. However, other studies have found that proximity to public transportation can also have adverse effects on property values. This paper investigates whether the implementation of the Greenbush Commuter line in Massachusetts in October 2007 increased the housing prices in Scituate, Ma--the furthest town from the ...

Forest Fire Risk Assessment Using Point Process Modeling & Monte Carlo Fire Simulation: A Case Study In Gyeongju, South Korea, Hyeyoung Woo 2017 University of Montana - Missoula

Forest Fire Risk Assessment Using Point Process Modeling & Monte Carlo Fire Simulation: A Case Study In Gyeongju, South Korea, Hyeyoung Woo

Hyeyoung Woo

Forest fire risk assessment becomes critical for developing forest and fire management strategies in Korea since the magnitude of damage from fires significantly increased over the past decades. Fire behavior probability is one of the major components in quantifying fire risk, and is often presented as burn probability. Burn probability estimation requires a proper estimation of fire occurrence probability because fire spread is largely influenced by ignition locations in addition to other environmental factors, such as weather, topography, and land covers.

The objective of this study is to assess forest fire risk over a large forested landscape in and around ...


The Effects Of Isoprene Emission From Native And Invasive Trees On Local Air Quality, Aarti P. Mistry 2017 DePaul University

The Effects Of Isoprene Emission From Native And Invasive Trees On Local Air Quality, Aarti P. Mistry

DePaul Discoveries

Biogenic volatile organic compounds (BVOC) are the second-most abundant reactive gasses emitted into the atmosphere by the biosphere. Isoprene is a BVOC produced by the process of photosynthesis from vegetation and is emitted from plant leaves. Isoprene is a hydrocarbon that combines with oxides of nitrogen in the atmosphere to create ozone in the troposphere, an air pollutant. Invasive trees alter ecosystems and affect native tree populations. Invasive tree species in the Chicagoland area are outcompeting native tree species and expanding rapidly. The effect of isoprene emissions on air quality is a well-researched area in the atmospheric science community, however ...

Regeneration Of Imperiled Hardwoods In The Eastern United States, Joshua J. Granger 2017 University of Tennessee, Knoxville

Regeneration Of Imperiled Hardwoods In The Eastern United States, Joshua J. Granger

Doctoral Dissertations

Our ability to successfully promote forest stand health and facilitate species under the threat of extinction will hinge on our ability to identify species regeneration requirements in an ever-changing environment. In the first chapter of this dissertation, I address what is known about the nature of threatened and imperiled hardwoods in the eastern United States, and in doing so, I identify several large knowledge gaps in current potentials and methodologies for regenerating them. In my second chapter, I use recent data from the United States Forest Service, Forest Inventory and Analysis program (FIA) to quantify ash regeneration counts across FIA ...


Herbivory Impacts On Growth And Survival Of Seedlings In Bottomland Hardwood Forest Restoration Sites In The Post Oak Savannah And Blackland Prairie Ecoregions Of Texas, Usa, Ryan J. Jacques 2017 Stephen F Austin State University

Herbivory Impacts On Growth And Survival Of Seedlings In Bottomland Hardwood Forest Restoration Sites In The Post Oak Savannah And Blackland Prairie Ecoregions Of Texas, Usa, Ryan J. Jacques

Electronic Theses and Dissertations

Interest in bottomland hardwood forests (BLHW) ecology and restoration has increased over the past 40 years. These communities aid in water quality improvement, streambank stabilization, and urban expansion mitigation. They also provide important habitat for many species of wildlife. Since the majority of remaining BLHW are degraded due to land fragmentation, restoration attempts are becoming commonplace within the Western Gulf Coastal Plain. However, restoration success has been mixed, with managers observing survival rates of <15% for desirable species due to various factors. Over two growing seasons, I investigated multiple factors that have potential to limit BLHW restoration success in East Texas. Specifically, I tested the impacts of herbivory by white-tailed deer (Odocoileus virginianus) and feral swine (Sus scrofa) on Nuttall oak (Quercus texana Buckley), Shumard oak (Q. shumardii Buckley), bur oak (Q. macrocarpa Michx.), and pecan (Carya ...


Influence Of Prescribed Burning On Upland Soil Properties In Mark Twain National Forest, Southeast Missouri Ozarks, Megan Lynn Hente 2017 Missouri State University

Influence Of Prescribed Burning On Upland Soil Properties In Mark Twain National Forest, Southeast Missouri Ozarks, Megan Lynn Hente

MSU Graduate Theses

In the Mark Twain National forest there is a collaborative effort to restore parts of the forest to its original shortleaf pine-oak woodland areas by using a combination of silviculture and prescribed fire. The purpose of this project is to assess the effects of prescribed burning on upland forest and soil physical properties that influence erosion processes across a gradient of burned sites of different ages and unburned sites. A combination of geospatial, field, laboratory, statistical (one-way ANOVA) and modeling (USLE) methods were used to assess the effects of prescribed burns on forest and soil characteristics in Big Barren Creek ...
