Tracing Sources of Soil Organic Matter Through Time, Across Ecosystems, and Down Soil Profiles

Creator:: Gallo, Adrian Carlos
Abstract:: Soils contain the largest pool of carbon that is actively cycling on human timescales, leading many to view soils as a natural climate solution with multiple co-benefits. The field of soil science is rapidly evolving, but without a unified understanding of soil carbon dynamics. This dissertation leverages two distinct long-term...

Estimation of Soil Particle Size Distribution using CT Scans

Creator:: Boath, Max E.
Abstract:: Remote sensing techniques have been applied extensively in geospatial investigations, but their use in measuring soil physical attributes has been far less explored. Soil particle size distributions (PSD) are indispensable in modeling pedological and hydrological processes as well as biodiversity. However, estimation of PSD via gravimetric measurement methods, the standard...

Modelling Early-Seral Vegetation Dynamics Using Climate and Soil Moisture

Creator:: Guevara, Claudio A.
Abstract:: Forest plantations in the Pacific Northwest are highly productive and have been intensively managed to maximize tree growth with practices such as Forest Vegetation Management (FVM). Different FVM regimes have been shown to enhance forest establishment by reducing the competition between the planted seedlings and early-seral vegetation. To better understand...

Forest Soils and Topography : Decoding the Influence of Physical Site Characteristics on Soil Water and Forest Productivity in Oregon's Coast Ranges

Creator:: Rodman, Henry
Abstract:: Forest soils and topography have long been known to influence forest productivity in complex terrain such as Oregon’s Coast Ranges. Incorporating physical site characteristics into predictions of forest growth and yield, however, has been problematic because of the high spatial variability of soil properties and the challenges associated with representing...

Relationship of Soil Type and Burn Severity to Post-Fire Vegetation Response

Creator:: Maclennan, Audrey
Abstract:: Public lands in the Pacific Northwest are managed for multiple uses including timber production, recreation and aesthetic value, maintaining wildlife habitat, conserving native species, and carbon storage. Wildfires impact large areas encompassing broad environmental conditions. Interactions among underlying environmental gradients and alteration of overstory competition by fire of varying severities...

Relationship of Soil Fungal Communities and Burn Severity to Post-Fire Vegetation Response

Creator:: Roach, Skylar K.
Abstract:: The effects of fire on above-ground forest systems have been extensively studied. However, research on fire effects on belowground processes is lacking. While the soil microbiome is understood to be vital to conifer growth and regeneration, the complexity of soils means that research on the topic has largely been accomplished...

Response of Soil Temperature, Moisture, and Respiration Two Years Following Intensive Organic Matter and Compaction Manipulations in Oregon Cascade Forests

Creator:: Gallo, Adrian Carlos
Abstract:: Forest soils contain a substantial portion of global terrestrial carbon stores. Forest management can influence the soil carbon pool and how soil organic matter functions. The long-term productivity of forests is an ongoing goal where land managers utilize biomass and timber. A site-specific understanding of intensively managed forests can ensure...

Insight into the Productivity, Cost and Soil Impacts of a Cable-assisted Harvester-forwarder Thinning in Western Oregon

Creator:: Green, Preston Q.
Abstract:: Timber harvesting in the Pacific Northwest (PNW) region of the United States of America (USA) has a long history of explosive growth, environmental litigation and regulation, economic downturn, and workforce dynamics that have created a current environment where cable-assisted harvesting is quickly gaining popularity among private and public land managers...

Long-term Effects of Vegetation Management on Plant and Soil Derived Nutrient Budgets for Plantations of Four Western Conifer Species

Creator:: Callan, Cannon F.
Abstract:: Forest Vegetation Management (VM) is an important tool used in the Pacific Northwest (PNW) for reforestation. It has been well documented that VM increases seedling survival and crop tree volume growth. What is less understood, is how altering the plant community and successional trajectory affects the way the ecosystem uses...

Top-Down Effects of Wildlife and Bottom-Up Drivers of Soils and Productivity in Intensively Managed Forest Plantations in the Northern Oregon Coast Range

Creator:: Frey, David W.
Abstract:: In intensively managed forest plantations in the northern Oregon Coast Range, herbicides are often applied during site preparation and early stand regeneration to reduce competition for resources for planted conifer seedlings. In addition to reducing competition for crop trees, herbicide applications may affect soil processes including decomposition and nutrient cycling,...
