Master’S Project: Vermont Town Forest Recreation Planning And Community Assistance Program: The Future Of Forest-Based Outdoor Recreation, Taylor M. Luneau Jan 2019

Master’S Project: Vermont Town Forest Recreation Planning And Community Assistance Program: The Future Of Forest-Based Outdoor Recreation, Taylor M. Luneau

Rubenstein School Masters Project Publications

The Vermont Town Forest Recreation Planning Community Assistance Program (VTFRP) was a comprehensive community planning process held in ten diverse towns across Vermont. Led by the Urban and Community Forestry Program and the SE Group, the VTFRP helped towns develop a vision for the future management of their forests through open house workshops, site visits, steering committee meetings, and community surveys. The process provided towns with a forest recreation planning toolkit and an individualized action-based forest stewardship and recreation plan. By analyzing data from the community surveys and open house activities across all ten towns, my project considered the recreation ...

Interactions Between Fire Severity And Forest Biota In The Central Sierra Nevada: Formation And Impact Of Small-Scale Fire Refugia And The Effect Of Fire On Forest Structure Predictive Of Fisher (Pekania Pennanti) Den Habitat, Erika M. Blomdahl Dec 2018

Interactions Between Fire Severity And Forest Biota In The Central Sierra Nevada: Formation And Impact Of Small-Scale Fire Refugia And The Effect Of Fire On Forest Structure Predictive Of Fisher (Pekania Pennanti) Den Habitat, Erika M. Blomdahl

All Graduate Theses and Dissertations

Fire is a natural and essential component of forests in western North America. Fire maintains biodiversity through the creation of different habitat types, and regular fire rotations reduce the accumulation of woody fuels and thick understory plant densities that give rise to catastrophic fire. The practice of fire exclusion has altered western forests and increased the risk of widespread change under rising temperatures projected for the 21st century. To manage for the reintroduction of fire it is critical that we understand the interactions between fire and forest biota in recently fire-suppressed forests.

In Chapter 2, I studied the formation ...


Ponderosa Pine Seedling Physiology After Severe Wildfire: Does It Take A Forest To Make A Forest?, Lauren Bansbach Nov 2018

Ponderosa Pine Seedling Physiology After Severe Wildfire: Does It Take A Forest To Make A Forest?, Lauren Bansbach

Shared Knowledge Conference

Ponderosa pine forests are an iconic ecosystem of western North America and provide numerous ecological, economic, and cultural benefits. Historically, these forests experienced regular surface fires that left most large, mature trees surviving. However, suppression of wildfires along with a warming climate have led to catastrophic tree-killing fires that result in vast areas (>200 mi2) dominated by shrubs and grasses. Because of limited survival of tree seedlings in these post-fire habitats, it remains unknown whether ponderosa pines can successfully recolonize severely burned landscapes. Without a mature tree canopy to provide periodic shade, seedlings experience hotter, drier conditions and likely experience ...


Mule Deer Impede Pando’S Recovery: Implications For Aspen Resilience From A Single-Genotype Forest, Paul C. Rogers, Darren J. Mcavoy Oct 2018

Mule Deer Impede Pando’S Recovery: Implications For Aspen Resilience From A Single-Genotype Forest, Paul C. Rogers, Darren J. Mcavoy

Ecology Center Publications

Aspen ecosystems (upland Populus-dominated forests) support diverse species assemblages in many parts of the northern hemisphere, yet are imperiled by common stressors. Extended drought, fire suppression, human development, and chronic herbivory serve to limit the sustainability of this keystone species. Here we assess conditions at a renowned quaking aspen (Populus tremuloides) grove—purportedly the largest living organism on earth—with ramifications for aspen biogeography globally. The “Pando” clone is 43 ha and estimated to contain 47,000 genetically identical aspen ramets. This iconic forest is threatened in particular by herbivory, and current management activities aim to reverse the potential ...


The Hydrologic Role Of Urban Green Space In Mitigating Flooding (Luohe, China), Tian Bai, Audrey L. Mayer, William D. Shuster, Guohang Tian Oct 2018

The Hydrologic Role Of Urban Green Space In Mitigating Flooding (Luohe, China), Tian Bai, Audrey L. Mayer, William D. Shuster, Guohang Tian

School of Forest Resources and Environmental Science Publications

Even if urban catchments are adequately drained by sewer infrastructures, flooding hotspots develop where ongoing development and poor coordination among utilities conspire with land use and land cover, drainage, and rainfall. We combined spatially explicit land use/land cover data from Luohe City (central China) with soil hydrology (as measured, green space hydraulic conductivity), topography, and observed chronic flooding to analyze the relationships between spatial patterns in pervious surface and flooding. When compared to spatial–structural metrics of land use/cover where flooding was commonly observed, we found that some areas expected to remain dry (given soil and elevation characteristics ...

Decadal Effects Of Thinning On Understory Light Environments And Plant Community Structure In A Subtropical Forest, Ho-Chen Tsai, Jyh-Min Chiang, Ryan Mcewan, Teng-Chiu Lin Oct 2018

Decadal Effects Of Thinning On Understory Light Environments And Plant Community Structure In A Subtropical Forest, Ho-Chen Tsai, Jyh-Min Chiang, Ryan Mcewan, Teng-Chiu Lin

Biology Faculty Publications

Canopy-opening disturbance such as thinning has immediate and substantive effects on understory microclimate and therefore the establishment and growth of understory plants. A large number of studies have reported the effects of thinning on tree growth, but few studies have examined long-term effects of thinning on understory light environments and species and functional diversity of understory plants. Even less is known whether the change in understory plant community structure observed following canopy disturbance is short-lived and would diminish as the canopy closes or a long lasting due to legacy effects. We examined the effects of an experimental removal of 25 ...

Increasing evidence indicates that forest disturbances are changing in response to global change, yet local variability in disturbance remains high. We quantified this considerable variability and analyzed whether recent disturbance episodes around the globe were consistently driven by climate, and if human influence modulates patterns of forest disturbance. We combined remote sensing data on recent (2001–2014) disturbances with in-depth local information for 50 protected landscapes and their surroundings across the temperate biome. Disturbance patterns are highly variable, and shaped by variation in disturbance agents and traits of prevailing tree species. However, high disturbance activity is consistently linked to warmer ...

Conservation Of Aquatic Biodiversity In The Context Of Multiple-Use Management On National Forest System Lands, Brett B. Roper, James M. Capurso, Yvette Paroz, Michael K. Young

Watershed Sciences Faculty Publications

The U.S. Department of Agriculture Forest Service (USFS) manages 193 million acres of public lands across 43 states and Puerto Rico. The original intent behind reserving lands managed by the USFS was to improve and protect forests, secure favorable conditions for water flows, and furnish a continuous supply of timber for the nation. Through time national forests have evolved, so they are managed for a broad array of uses. Differing expectations have led to conflicts between aquatic conservation and other aspects of the USFS’ mandate. In the 1990s, these conflicting goals came to a head with the listing of ...

Printed Dot Quality In Response To Doctor Blade Angle In Gravure Printing, Bilge N. Altay, Alexandra Pekarovicova, Paul D. Fleming Aug 2018

Printed Dot Quality In Response To Doctor Blade Angle In Gravure Printing, Bilge N. Altay, Alexandra Pekarovicova, Paul D. Fleming

The Hilltop Review

Doctor blade is one of the critical machine part of the gravure printing press that controls the amount of ink transfer on the substrate. The angle of the blade can be varied; however, an improper angle may cause major problems. In this study, the doctor blade angle was positioned at three different level to address its effect on the printed dot quality. Print trials were made on a web-fed gravure press at the speed of 650 ft./min. A high-resolution overhead camera was used to analyze the key dot attributes. The results showed that measuring only the density of printed ...


Baldcypress And Black Willow Growth Response To Contrasting Flood Regimes, Climate, And Competition, In The Atchafalaya Basin, Louisiana, Alicia Louise Mcalhaney Aug 2018

Baldcypress And Black Willow Growth Response To Contrasting Flood Regimes, Climate, And Competition, In The Atchafalaya Basin, Louisiana, Alicia Louise Mcalhaney

LSU Master's Theses

Wetlands are dynamic ecosystems distinguished by their dependence on fluctuations of hydrologic influence. Although it is generally accepted that that flooding is a strong influence on growth, and that effects vary depending on whether water is stagnant or flowing, several aspects of flood characteristics and several tree species remain poorly investigated. One source of variability that has not been investigated is how flooding, climate, and competition among trees interact to control growth of individual trees. The objective of this study was therefore to 1) investigate effects of temporally varying hydrology and climate on growth of baldcypress and black willow trees ...


Drivers Of Tree Growth And Mortality In An Uneven-Aged, Mixed-Species Conifer Forest Of Northeastern United States, Erin Fien Aug 2018

Drivers Of Tree Growth And Mortality In An Uneven-Aged, Mixed-Species Conifer Forest Of Northeastern United States, Erin Fien

Electronic Theses and Dissertations

Individual tree growth and mortality drive forest stand dynamics and are important, universal metrics of tree success. Studying the factors that affect growth and mortality is particularly challenging in mixed-species, uneven-aged systems due to their defining heterogeneity and strong temporal and spatial variability. However a better understanding of the factors driving growth and mortality in mixed-species, uneven-aged forest is crucial to managing and maintaining these valuable systems for the future.

The goal of this study was to determine the relative importance of individual tree attributes (e.g., species, size, neighborhood crowding, crown position) and environmental characteristics (e.g., soil moisture ...


Nitrogen Cycling During A Period Of Environmental Change, Kaizad Patel Aug 2018

Nitrogen Cycling During A Period Of Environmental Change, Kaizad Patel

Electronic Theses and Dissertations

Natural and anthropogenic disturbances have altered the N cycle on the regional to global scale. Although numerous studies have examined the effects of chronic atmospheric N deposition on ecosystem processes, less is known about intra-annual variability of these processes, or how these responses might be altered under conditions of changing climate. The work described in this dissertation focuses on the effects of a changing chemical and physical climate, particularly terrestrial N processes (a) during Maine’s changing winters, and (b) in response to chronic elevated N additions.

Subnivean winter soil processes were examined at the Dwight B. DeMerritt Forest (DBDF ...


Forest Disturbance Detection And Aboveground Biomass Modeling Using Moderate-Resolution, Time-Series Satellite Imagery, John B. Kilbride Aug 2018

Forest Disturbance Detection And Aboveground Biomass Modeling Using Moderate-Resolution, Time-Series Satellite Imagery, John B. Kilbride

Electronic Theses and Dissertations

Human-induced and natural disturbances are an important feature of forest ecosystems. Disturbances influence forest structure and composition and can impact crucial ecosystem services. However, deriving spatially explicit estimates of past forest disturbance across a large region can prove challenging. Researchers have recognized that remote sensing is an important tool for monitoring forest ecosystems and mapping land use and land cover change. One of the most important sources of remotely sensed imagery is the United States Geologic Survey’s Landsat program which has continuously acquired earth observations since 1972. This repository of imagery has the spatial, spectral, and temporal resolution necessary ...


Characterization Of Sites For Native Herbaceous Understory Restoration In West Gulf Coast Longleaf Pine (Pinus Palustris) Savannas, Brooke Mccalip Aug 2018

Characterization Of Sites For Native Herbaceous Understory Restoration In West Gulf Coast Longleaf Pine (Pinus Palustris) Savannas, Brooke Mccalip

Electronic Theses and Dissertations

Longleaf pine (Pinus palustris) savannas were once dominant in East Texas and parts of western and central Louisiana. Native understory species have since been removed or reduced by exotic plants that were introduced and from the reduction in the frequency of both wild and prescribed fires. A diverse layer of understory species can still be seen today, but not often in the historical savanna setting that is desirable in longleaf pine ecosystems. This project aimed to identify site characteristics associated with longleaf ecosystems that support a dense, herbaceous understory with little to no midstory cover.

Flow Regime Influences On Stream And Riparian Soil Carbon Dynamics In The Ozark Highlands And Boston Mountains Of Arkansas, Allyn Dodd Aug 2018

Flow Regime Influences On Stream And Riparian Soil Carbon Dynamics In The Ozark Highlands And Boston Mountains Of Arkansas, Allyn Dodd

Theses and Dissertations

The natural flow regime exerts primacy over lotic ecosystem patterns and processes. However, little work has examined the influence of flow regime on instream and riparian carbon (C) dynamics in minimally-impacted, temperate forested systems. To date, most research efforts have focused on characterizing C movement and transformations across biomes and land use categories; however, flow regime represents an overlooked, finer level of detail that may drive differences in ecosystem function. My dissertation objective was to measure C fixation and movement within and across multiple environmental spheres (e.g. within stream channels, between stream surfaces and the atmosphere, and from riparian ...

Landscape Drivers Of Recent Fire Activity (2001- 2017) In South-Central Chile, David B. Mcwethy, Aníbal Pauchard, Rafeal García, Andrés Holz, Mauro E. Gonzales, Thomas T. Veblen, Julian Stahl, Bryce Currey

Geography Faculty Publications and Presentations

In recent decades large fires have affected communities throughout central and southern Chile with great social and ecological consequences. Despite this high fire activity, the controls and drivers and the spatiotemporal pattern of fires are not well understood. To identify the large-scale trends and drivers of recent fire activity across six regions in south-central Chile (~32–40° S Latitude) we evaluated MODIS satellite-derived fire detections and compared this data with Chilean Forest Service records for the period 2001–2017. MODIS burned area estimates provide a spatially and temporally comprehensive record of fire activity across an important bioclimatic transition zone between ...

Land Cover And Use Change In Utah: A Comparison Of Field- Vs. Aerial Image-Based Observations, Jennifer Lynn Bakken

All Graduate Theses and Dissertations

The Image-based Change Estimation program (ICE) was developed by the US Forest Service Forest Inventory & Analysis (FIA) program and the Geospatial Technology Applications Center in response to the 2014 Farm Bill calling for more timely and accurate estimates of land cover and use change. ICE monitors change throughout the US on a state by state basis by assessing each FIA plot using high resolution imagery from two dates in time. In the western US, FIA measures 10% of the plots each year to report on status, trends, and sustainability of our Nation’s forests. However, this 10 year cycle misses ...


Removal Of Invasive Plants From Pando Exclosure 2018, Marc Coles-Ritchie Jul 2018

Removal Of Invasive Plants From Pando Exclosure 2018, Marc Coles-Ritchie

Aspen Bibliography

On July 10-11, 2018 volunteers and staff from Great Old Broads for Wilderness and Grand Canyon Trust removed invasive plants from the Pando exclosure, a fenced portion of the Pando Clone aspen forest adjacent to Fish Lake, in Central Utah. This area has been fenced to restore a portion of the Pando Clone that has been lacking recruitment for decades, by protecting young aspen from browsing by deer and cattle. We have been removing invasive species for five years from this exclosure.

The 2018 trip included 10 women and one staffer of Great Old Broads for Wilderness, from the states ...


Air Pollution And Visitation At U.S. National Parks, David A. Keiser, Gabriel E. Lade, Ivan Rudik Jul 2018

Air Pollution And Visitation At U.S. National Parks, David A. Keiser, Gabriel E. Lade, Ivan Rudik

Economics Publications

Hundreds of millions of visitors travel to U.S. national parks every year to visit America’s iconic landscapes. Concerns about air quality in these areas have led to strict, yet controversial pollution control policies. We document pollution trends in U.S. national parks and estimate the relationship between pollution and park visitation. From 1990 to 2014, average ozone concentrations in national parks were statistically indistinguishable from the 20 largest U.S. metropolitan areas. Further, relative to U.S. cities, national parks have seen only modest reductions in days with ozone concentrations exceeding levels deemed unhealthy by the U.S ...

Physiological Responses Of Species To Microclimate Help Explain Population Dynamics Along Succession In A Tropical Dry Forest Of Yucatan, Mexico, Paula C. Jackson, José Luis Andrade, Casandra Reyes-García, Olivia Hernández-González, Thomas C. Mcelroy, Roberth Us-Santamaría, José Luis Simá, Juan Manuel Dupuy

Faculty Publications

We investigated relationships between population dynamics and microclimate, physiology, and the degree of mycorrhizal colonization, for three species (Piscidia piscipula L.(Sarg.)) (Fabaceae), Bunchosia swartzianaGriseb. (Malpighiaceae) and Psidium sartorianum (Bergius) Nied. (Myrtaceae)) of a tropical sub deciduous forest in Yucatan, Mexico that were growing in plots of different successional ages. We hypothesized that abundance and persistence were related to increased plasticity in CO2assimilation. We found that Piscidia piscipula had greater abundance in intermediate plots (18 to 21 years), presented higher levels of plasticity in CO2 assimilation (greater variability among individuals, plots, and seasons), presented the highest CO2 assimilation rates, and ...

Using Transboundary Wildfire Exposure Assessments To Improve Fire Management Programs: A Case Study In Greece, Palaiologos Palaiologou, Alan A. Ager, Max Nielsen-Pincus, Cody Evers, Kostas Kalabokidis

Environmental Science and Management Faculty Publications and Presentations

Numerous catastrophic wildfires in Greece have demonstrated that relying on fire suppression as the primary risk-management strategy is inadequate and that existing wildfire-risk governance needs to be re-examined. In this research, we used simulation modelling to assess the spatial scale of wildfire exposure to communities and cultural monuments in Chalkidiki, Greece. The study area typifies many areas in Greece in terms of fire regimes, ownership patterns and fire-risk mitigation. Fire-transmission networks were built to quantify connectivity among land tenures and populated places. We found that agricultural and unmanaged wildlands are key land categories that transmit fire exposure to other land ...


Assessment Of The Ponderosa Woodlands In Nebraska's Wildcat Hills: Implications For Juniperus Encroachment And Management, Allie Victoria Schiltmeyer Jul 2018

Assessment Of The Ponderosa Woodlands In Nebraska's Wildcat Hills: Implications For Juniperus Encroachment And Management, Allie Victoria Schiltmeyer

Dissertations & Theses in Natural Resources

Ponderosa pine (Pinus ponderosa) is a dominant tree species across western North America. Its eastern distribution includes three populations in western Nebraska. This study assesses the distribution, structure and age of ponderosa pine woodlands in one of those regions, the Wildcat Hills. The Wildcat Hills have escaped severe wildfires seen in recent decades in other ponderosa pine regions. Nevertheless, the Wildcat Hills woodlands face multiple threats including climate change, wildfire, drought, pine beetles, and invasive species. Key to these threats is the stand structure of pine woodlands, which have increased in density across much of ponderosa pine’s range. These ...
