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 …
Environmental Implications Of Modern Food Production: An Analysis For The Conscious Consumer, Jessica T. Coming
Environmental Implications Of Modern Food Production: An Analysis For The Conscious Consumer, Jessica T. Coming
Cal Poly Humboldt theses and projects
This project explores the pathways by which agriculture affects the environment and determines which foods have the greatest climate, water, and land impacts. Agricultural effects on the environment are extensive, from loss of habitat and declines in regional biodiversity to disruption of global nutrient cycles and climate change. Global food production accounts for 26-34% of annual anthropogenic greenhouse gas emissions, makes up 38-46% of habitable land, and is responsible for 70% of freshwater extraction. The effect of agriculture on the environment is most significantly dictated by what type of food is being produced. Animal-based food products consistently have the highest …
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 …
Satellite-Based Phenology And Climate Anomaly Analysis In Evaluating The Response Of Puerto Rico And The U.S. Virgin Islands Tropical Forests To The 2015-2016 Drought, Sean Fleming
Cal Poly Humboldt theses and projects
The health and overall resilience of tropical forest ecosystems are closely tied to the timing of phenological events. One must consider how forests react to significant climate anomalies to forecast the possible effects of climate change. This research study utilized U.S. Forest Service Forest Inventory Analysis (FIA) plot-level data and Landsat satellite data together to determine if these datasets are valuable techniques to understand the impacts of the 2015-2016 drought on Puerto Rico and the U.S. Virgin Islands (PRVI). I did remote sensing analysis on PRVI to produce repaired and near cloud-free satellite imagery, producing dozens of phenometrics of all …
