Short-Term Impacts Of Biochar And Mycorrhizal Inoculation For Pinus Echinata Reforestation On Strip-Mined Soils, Casey Iwamoto, Courtney Siegert, Joshua J. Granger, Adam Polinko, Krishna P. Poudel, Zachary Freedman

FWRC Publications

Coal strip mining has left widespread degraded soils throughout the southeastern US. These soils tend to have low pH, high bulk density, impacted hydrologic processes, and an accumulation of heavy metals that limit revegetation efforts. Shortleaf pine (Pinus echinata) is an ideal species for these reforestation efforts as it can tolerate the poor conditions on post-mined sites and has the largest native pine range in the southeastern US, overlapping with many post-mined areas. However, limited empirical field studies have been conducted on the success of soil amendments for soil physical, chemical, biological properties and tree growth. To fill …

Effects Of Climate Change On Seed Germination May Contribute To Habitat Homogenization In Freshwater Forested Wetlands, Kori Carr, Xavier Ozowara, Taylor M. Sloey

Biological Sciences Faculty Publications

Climate changes in temperate regions are expected to result in warmer, shorter winters in temperate latitudes. These changes may have consequences for germination of plant species that require a period of physiological dormancy. The effect of cold duration on seed germination has been investigated in a number of plant taxa, but has not been well studied in wetland and bottomland forest tree species, an ecosystem that is threatened by habitat homogenization. Our work sought to test the role of changing winter temperatures on seed germination in specialist (Nyssa aquatica and Taxodium distichum) and generalist (Acer rubrum and Liquidambar styraciflua) tree …

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 …

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 …

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 …

Nebraska Anthropologist

Forensic Archaeology Protocols for Wildfires and Fire-Related Scenes

Forensic archaeology is a relatively new area of study and focuses on the medical legal aspects of archaeology. This paper will focus on how forensic archaeology should be used for wildfire and other fire-related fatalities or investigations, what happens to bone when exposed to heat, what protocols should be in place and how an excavation should look, and finally the challenges of fire-related investigations. This report will focus on the larger scale of the investigation and will be using several sources from different wildfire and fire fatality reports.

Aspen Forest Condition Assessment And Restoration Guidance, Paul C. Rogers

Aspen Bibliography

This preliminary report is the first installment of an ongoing aspen assessment at Bryce Canyon National Park (BCNP). Over a 1.5-year period beginning in 2021, I assembled available BCNP and conducted a preliminary field survey to gain a better understanding of the quaking aspen (Populus tremuloides) resource within the Park. Findings suggest a long history of vegetation mapping with mixed results in terms of highlighting aspen presence a notable species of overall low coverage as well as aspen importance, at BCNP. In brief, though this species has limited presence, it is of high biodiversity conservation value. According to …

Africa’S Overlooked Top Predator: Towards A Better Understanding Of Martial Eagle Feeding Ecology In The Maasai Mara, Kenya, Richard Stratton Hatfield, Allison G. Davis, Ralph Buij, John J. Cox, Shiv Kapila, Lemein Parmuntoro, Simon Thomsett, Munir Z. Virani, Peter Njoroge, Frank Van Langevelde

Forestry and Natural Resources Faculty Publications

Raptors exert top-down influences on ecosystems via their effects on prey population dynamics and community composition. Most raptors are sympatric with other predators, thus complicating our understanding of their relative influence in these systems. Estimates of kill rates and prey biomass recycling have been used as predation metrics that allow quantitative comparison among species and assessment of the relative role of single species within complex food webs. Few studies have produced findings of kill rates or prey biomass recycling for raptors. We used a supervised machine learning algorithm to behaviourally classify high resolution accelerometer informed GPS locations of tagged adult …

Persistent Net Release Of Carbon Dioxide And Methane From An Alaskan Lowland Boreal Peatland Complex, Eugénie S. Euskirchen, Colin W. Edgar, Evan Kane, Mark P. Waldrop, Rebecca B. Neumann, Kristen L. Manies, Thomas A. Douglas, Catherine Dieleman, Miriam C. Jones, Merritt R. Turetsky

Michigan Tech Publications

Permafrost degradation in peatlands is altering vegetation and soil properties and impacting net carbon storage. We studied four adjacent sites in Alaska with varied permafrost regimes, including a black spruce forest on a peat plateau with permafrost, two collapse scar bogs of different ages formed following thermokarst, and a rich fen without permafrost. Measurements included year-round eddy covariance estimates of net carbon dioxide (CO2), mid-April to October methane (CH4) emissions, and environmental variables. From 2011 to 2022, annual rainfall was above the historical average, snow water equivalent increased, and snow-season duration shortened due to later snow return. Seasonally thawed active …

An Rnai-Based Approach To Ips Calligraphus Management: A Promising Strategy For Forest Protection, Mary Wallace

Theses and Dissertations--Entomology

As climate change leads to more frequent and severe extreme weather, host tree stress is increasing the occurrence of large-scale bark beetle outbreaks. One such beetle, Ips calligraphus (Germar), a native bark beetle in the southeastern United States, has traditionally been considered a secondary pest of pine trees. Management has relied on silvicultural practices that enhance forest resilience, enabling host trees to effectively use natural defenses to deter beetle infestation. However, during periods of forest stress caused by storms, droughts, human disturbance, and other factors, beetle outbreaks can cause considerable ecological and economic damage.

Addressing worsening I. calligraphus outbreaks will …

Undergraduate Scholarship

Development of additional revenue streams for timber products with relatively low profitability is an important step in securing future economic success for the forestry sector in Humboldt county. Utilization of California Sitka spruce (Picea sitchensis) for use in domestic acoustic steel-string guitar manufacturing may provide exactly that. Determining the quality and quantity of California Sitka spruce is the logical first step in achieving this.

Quality was determined from tree core samples gathered at sites on Green Diamond Resource Company’s (GDRco) California timberlands and the Arcata Community Forest (ACF) with high basal area of Sitka spruce. Rings Per Inch …

Felling For Photovoltaics: Remote Sensing For The Detection Of Solar Facilities In Maine, James A. Lane

Honors Theses

Solar power is an area with increasing development in the State of Maine. Photovoltaic solar, which uses large arrays of panels constructed on facilities of several hectares, is an ideal renewable energy source for Maine, because of its low population density and small proportion of conserved lands. Since most of the state of Maine is forested, the development of photovoltaic solar will require increasing amounts of deforestation. Environmental impacts of this deforestation include loss of carbon sequestration, erosion, damage to habitat, and inhibition of other forest benefits. This study uses Landsat data and remote sensing to analyze a large portion …

Data From: Phylogenomic Species Delimitation Of Studfishes (Fundulidae: Fundulus): Evidence For Cryptic Species In Agreement With The Central Highlands Vicariance Hypothesis, Kayla M. Fast, Peter J. Hundt, Zachariah D. Alley, Michael W. Sandel

CFR Publications

The Central Highlands ecoregion of the eastern United States represents a hotspot of freshwater biodiversity, with replicated patterns of vicariant speciation east and west of the Mississippi River. Previous phylogeographic investigation of the studfishes (Fundulus subgenus Fundulus) revealed evidence for vicariant speciation in the Central Highlands, but data were limited to a small number of gene sequences generated with Sanger sequencing. We used double digest restriction-site associated DNA sequencing (ddRADseq) to improve resolution of phylogeographic patterns and better characterize population genetic variation. Our sample design included individuals from the Fundulus catenatus species group (F. catenatus, F. bifax, …

Practical Challenges In Delivering Dsrna For Woody Plant Protection, Zachary Bragg

Theses and Dissertations--Entomology

Unprecedented weather events associated with climate change, coupled with extensive anthropogenic stresses, have reduced the effectiveness of traditional forest pest management approaches, which can no longer keep pace with invasive species overwhelming naïve landscapes and native pests experiencing eruptive and expansive outbreaks. Double-stranded RNA-(dsRNA) mediated gene silencing, a type of RNA interference (RNAi), has been coopted for use as a biopesticide against a multitude of agricultural and horticultural pests and could serve as a powerful tool for woody plant protection. While effective initiation of gene silencing and subsequent mortality have been demonstrated in multiple tree pests, effective and efficient methods …
