Automated Tree Mortality Detection Using Ubiquitously Available Public Data, Michael T. Huggins
Automated Tree Mortality Detection Using Ubiquitously Available Public Data, Michael T. Huggins
Master's Theses
Understanding the dynamic interplay between fire severity, topography, and tree mortality, is crucial for predicting future forest dynamics and enhancing resilience against climate change-induced wildfire regimes. This thesis develops a multi-sensor approach for automated estimation of tree mortality, then applies it to examine trends in tree mortality over a six-year period across a fire affected study site in the Trinity River basin in Northern California. The Random Forest model uses publicly available USGS 3D Elevation Program Lidar (3DEP) and NAIP imagery as inputs and is likely to be easily adaptable to other landscapes. The model had a Receiver Operating Characteristic …
Post-Fire Persistance Of Sequoia Semperviens In A Secondary Forest: Examining Drivers Of Basal Resprouting Response, Jackson T. Carrasco
Post-Fire Persistance Of Sequoia Semperviens In A Secondary Forest: Examining Drivers Of Basal Resprouting Response, Jackson T. Carrasco
Cal Poly Humboldt theses and projects
Historically frequent-fire forest ecosystems are now facing increased size, frequency, and severity of fires attributed to climate change, intensive forest management, and fire exclusion. Understanding post-fire resilience in forest ecosystems is critical amidst escalating challenges posed by recent increases in fire activity. This study examined the basal resprouting response of coast redwood (Sequoia sempervirens) in a secondary forest two years after the CZU Lightning Complex fire on the central coast of California. Robust allometric equations were developed to quantify redwood resprout biomass and leaf area, revealing strong explanatory power for biomass equations (R² > 0.85). Probability of …
Longevity Of Prescribed Fire Effectiveness In Mixed-Evergreen Forests Of The Klamath Mountains, Kaily M. Fineran
Longevity Of Prescribed Fire Effectiveness In Mixed-Evergreen Forests Of The Klamath Mountains, Kaily M. Fineran
Cal Poly Humboldt theses and projects
Prescribed fire is a common management tool used across the western United States to create wildfire-resilient ecosystems and communities. The Klamath Mountains of northern California, USA has experienced numerous, large wildfires in recent years. This is due in part to a combination of highly flammable fuels, uncharacteristic weather events, and high fuel accumulations as a result of fire exclusion and forest management practices. Within the last decade, local land management organizations and the Karuk Tribe have begun re-introducing prescribed fire in low elevation, mixed evergreen forests. While the long-term effects of fuel treatments are not well-known, these efforts provided a …
Quantification Of Influential Surface Fuel Parameters In Fire-Prone Ecosystems Of The Netherlands, Lauren Lara
Quantification Of Influential Surface Fuel Parameters In Fire-Prone Ecosystems Of The Netherlands, Lauren Lara
Electronic Theses and Dissertations
Changing climate conditions in northwest Europe present an increasing wildfire risk in the Netherlands. Focus on fuels monitoring in this region is not as extensive as it is in the United States. Accurate estimation of biomass fuel loading is integral to prevention of wildfires which pose a significant risk to both human lives and property. This research project attempted to create predictive models for three major fuel categories (litter/duff, shrub, and downed woody material). Reduction of the number of parameters to measure would streamline the process of fuel load estimation by reducing the number of measurements that need to be …
The Art And Science Of Wood: From Pyrography To Termites And Wood Decomposition, Joanna D. Walitalo
The Art And Science Of Wood: From Pyrography To Termites And Wood Decomposition, Joanna D. Walitalo
Dissertations, Master's Theses and Master's Reports
Wood is vital to many natural ecosystems, as it provides energy, nutrients, and habitat for organisms from the micro- to the macro- scale. Wood is also critical to humans for similar reasons, and can be an important medium of art and education. This dissertation addresses three diverse aspects of wood with the contexts of science, art, and education. First, we explored the impact of timber harvest techniques and site preparation on microbial wood decay and subterranean termite responses on a forest-stand scale. The amount of coarse woody debris removed post-harvest, coupled with the location and species of the test wood …
The Role Of Edge Effects On Emerald Ash Borer Infestation And Forest Responses, Bronte Hoefer
The Role Of Edge Effects On Emerald Ash Borer Infestation And Forest Responses, Bronte Hoefer
Undergraduate Honors Theses
The emerald ash borer (EAB; Agrilus planipennis) is a buprestid beetle native to Asia, classified as an invasive species in North America. EAB infests trees of genus Fraxinus (ash) and has spread to 35 states since its introduction in the early to mid-1990s. Notably, EAB has the potential to functionally extirpate all native ash species in North America. Our study aims to characterize the ecological impacts of EAB infestation in the Roanoke Valley of Southwest Virginia, to quantify the impact of edge effects on EAB forest invasion and mortality of ash trees, as well as investigate the role that …
Lidar-Landsat Covariance For Predicting Canopy Fuels, Margaret D. Epstein
Lidar-Landsat Covariance For Predicting Canopy Fuels, Margaret D. Epstein
Graduate Student Theses, Dissertations, & Professional Papers
Managing wildfires in the western United States is becoming increasingly complex. Visualizing and quantifying canopy structures allows fire managers to both plan for fire and track recovery. Light detecting and ranging, or LiDAR can measure forests in three dimensions, but has limited spatial and temporal coverage. LiDAR-Landsat covariance uses machine learning to fill in the spatial and temporal gaps of LiDAR coverage with supplemental Landsat imagery. However, in order to capture real forest dynamics, a model needs to be stable enough to detect long term trends, sensitive to episodic disturbance, and general enough to work on multiple landcovers. The purpose …
In-Flux: Economic And Community Adaptations Of Former Timber Mill-Towns In The American West, Cherilyn P. Ashmead
In-Flux: Economic And Community Adaptations Of Former Timber Mill-Towns In The American West, Cherilyn P. Ashmead
Cal Poly Humboldt theses and projects
Once built around natural resource extractive industries, rural communities’ economies are changing as the United States is transitioning away from its industrial past. While much research has focused on rural economic shifts from natural resource production toward amenity-driven economies (Morzillo et al., 2015; Winkler et al, 2007), less research has explored the economic and demographic trends in areas pursuing new modes of production. This two-part study focuses on an understudied region with historic ties to timber in dry mixed-conifer forests, much of which are under federal land management. With few natural amenity draws, the region has largely maintained production-based sectors. …

Sula Study Revisited: 20-Year Post-Fire Regeneration In The Southern Bitterroot Valley, Montana., Luke Alan Rymniak
Graduate Student Theses, Dissertations, & Professional Papers
In the summer of 2000, a number of large fires burned in the southern Bitterroot Valley near Sula, Montana. Research was conducted in 2001 and 2003 in the fire-affected areas of the French Basin and Larid Creek areas in order to investigate the effects of environmental variables, fire severity, and post-fire management on vegetation regeneration. In 2020 these areas were remeasured to understand trends over time by evaluating the impact of these same factors 20 years post fire. The results showed that the effects of environmental variables, fire severity, and post-fire management on vegetation regeneration were varied. The most influential …

Severe Thunderstorms Create Windfall Of Opportunity For Ecosystem-Based Management Of Mixed Northern Hardwoods, Elizabeth Montgomery Barnes
Severe Thunderstorms Create Windfall Of Opportunity For Ecosystem-Based Management Of Mixed Northern Hardwoods, Elizabeth Montgomery Barnes
Dissertations, Master's Theses and Master's Reports
The regeneration and reorganization of organisms and their habitat post-disturbance is a primary mechanism by which ecosystems maintain functionality in a changing environment. This adaptation to disturbance lends dynamism and resiliency to landscapes. Yet, the 20th century was marked by an alarming loss of global biodiversity, pointing to the likelihood that the rate of ecological disturbance generated by human systems today is either too frequent or too intense to be beneficial to ecosystems, and rather poses a risk to ecosystem functionality and the carrying capacity of Earth systems. Compounding these risks is high uncertainty regarding the potential for stronger, …
A Qualitative Case Study Of Student Persistence In A Bachelor Of Science In Forestry Program, Maxwell Holmes
A Qualitative Case Study Of Student Persistence In A Bachelor Of Science In Forestry Program, Maxwell Holmes
Electronic Theses and Dissertations
Educational leaders in forestry have been challenged to increase and diversify the pipeline of ‘society ready’ foresters. To meet these challenges, leaders must shift their focus to student retention. By understanding the factors that influence student engagement and persistence, these leaders will be better positioned to support students in forestry programs, thus positively impacting retention. This qualitative case study investigated student persistence of second-year forestry students in an undergraduate forestry program. The study was guided by Social Cognitive Theory and Social Capital Theory and explored the malleable psychosocial mechanisms of self-efficacy, sense of belonging, emotion, and well-being proposed by Kahu …

Using The Forestry Reclamation Approach For Reclaimed Surface Mineland In The Western Gulf: Effects On Pinus Taeda Seedling Growth And Survival, Cassie Phillips, Jeremy Stovall, Hans Williams, Kenneth Farrish
Electronic Theses and Dissertations
While land reclamation efforts of surface mines have considerably increased soil stability since the implementation of SMCRA (Surface Mining Control and Reclamation Act), research suggests that resulting soil compaction hinders the productivity of forests post-mining. The Forestry Reclamation Approach (FRA) was developed to improve forest health in the Appalachian region through a five-step process that minimizes soil compaction and establishes a productive forest. The FRA has not yet been tested in the western Gulf Coastal Plain (GCP). The higher clay content of some GCP soils and the dearth of coarse fragments (e.g. cobbles, stones and boulders) may affect reclamation practices …

A better understanding of the value of ecosystem services and their spatial distribution in urban areas is vital to widespread, wholistic understanding of the relationship of environmental, economic, and social conditions. As such, it should be a component of education in grades 6-12, college, and continuing education. i-Tree Landscape is a free, online model developed by the USDA Forest Service in which users can select a geography (i.e. …
Soil Organic Matter Distribution In A Douglas-Fir-Tanoak Forest, Humboldt County, California, Hollie A. Ernest
Soil Organic Matter Distribution In A Douglas-Fir-Tanoak Forest, Humboldt County, California, Hollie A. Ernest
Cal Poly Humboldt theses and projects
Soil carbon (C) affects the active gases in the atmosphere, nutrient cycling, and diversity of flora and fauna. Soil organic matter (SOM) is partially comprised of C, and a widely-accepted ratio of 0.58 organic carbon (OC) to organic matter (OM) is used to measure soil C on a landscape scale. However, this ratio varies according to vegetation, depth, hydrology, and may lead to miscalculations of soil C and SOM estimates. Soil C and SOM are inherently complex and it is not completely understood which environmental factors have the most influence in their formation, which occurs on a time scale of …

Accuracy Of Forest Road And Stream Channel Characteristics Derived From Lidar In Forested Mountain Conditions, Russell Alan White
Accuracy Of Forest Road And Stream Channel Characteristics Derived From Lidar In Forested Mountain Conditions, Russell Alan White
Master's Theses
Forest roads and stream channels are mapped using a variety of remote sensing and ground-based techniques. In densely forested areas, conventional remote sensing methods provide limited terrain information, while ground-based surveys can be time-consuming, difficult, and expensive. Light Detection and Ranging (LiDAR) is an airborne remote sensing technology used to create high-resolution digital elevation models (DEMs) of the earth’s surface. This study tests the accuracy of forest road and stream channel features mapped using LiDAR in the steep, forested terrain of California’s Santa Cruz Mountains. A conventional total station survey was used to determine centerline position and elevations along a …

This book describes the various growth patterns of forests from a mechanistic point of view. Its purpose is to help silviculturists, forest managers, and ecologists understand and anticipate how forests grow and respond to intentional manipulations and natural disturbances. Demands on the forest have been increasing for timber production, wildlife habitat, water protection, recreation, and protection from fires, insects, and diseases. These demands have created an emphasis on prescribing site-specific treatments for individual stands of trees, rather than treating broad areas uniformly
