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...

Fuel Treatments of Ponderosa Pine (Pinus ponderosa) in the Blue Mountains of Eastern Oregon : A Mycorrhiza Perspective

Creator:: Hart, Benjamin T. N.
Abstract:: Over the course of the last century, a successful history of fire suppression has contributed to unsuccessful present day control over wildfire. In the absence of fire and the janitorial and ecological services it provides, drier inland forests are shifting in species composition and exceeding densities that cannot survive and...

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...

Runoff and Sediment Transport from Harvested Hillslopes to Riparian Buffers of Rocky Mountain Headwater Catchment

Creator:: Puntenney-Desmond, Kira C.
Abstract:: Shallow subsurface flow and surface runoff are spatially and temporally variable in forested environments. The location and timing of this runoff depends on both site characteristics (e.g., vegetation, soil texture, geology, and topography) and on time-varying conditions (e.g., soil water content, precipitation type, duration, magnitude, and intensity). Forest management activities...

Lithologic Controls on Soil Carbon Partitioning in the Alaskan Coastal Temperate Rainforest

Creator:: Fleiner, Julia H.
Abstract:: Coastal Temperate Rainforests of western North America are carbon dense ecological regions of great importance due to their high biological productivity and climatic conditions leading to the natural accumulation of soil organic carbon (SOC). Yet, the distribution of SOC remains understudied in the CTR environments, particularly in upland mineral soils,...

Impact of Climate and Disturbance on the Formation of Earlywood and Latewood in Douglas-fir at the Salal Fields Study Site

Creator:: Gourley, Derek M. F.
Abstract:: Wood density is controlled to a large extent by the relative widths of earlywood and latewood in the stem, but the mechanisms controlling these amounts are poorly understood in coastal Douglas-fir. To understand the role of climatic factors, one hundred and thirty-six increment cores were collected and measured from the...

Predicting the spatial variability in soil properties using DSM across Malheur National Forest

Creator:: Seeno, Elizabeth A.
Abstract:: Soil properties may hold the key to improved predictions of soils during digital soil mapping (DSM), which has developed with a focus on environmental factors external to soil. The spatial variability in soil properties was modeled across Malheur National Forest in eastern Oregon as an approach to improve DSM. The...

A Political Ecology Lens for the Nutrition Transition in Rural, Kedougou, Senegal

Creator:: Lucey, Taylor K.
Abstract:: The nutrition transition is a global phenomenon in which populations move from low socioeconomic status (SES) to high SES and from high physical activity to low physical activity. Rising rates of urbanization and non-communicable diseases in West Africa may indicate an advanced phase of the nutrition transition; however, through a...

Post-fire Forest Management Activities Alter Soil Properties, Sediment Yields, and Vegetation Recovery in the Northern California Coast Range

Creator:: Cole, Ryan P.
Abstract:: The extent and severity of wildfires in forested regions are increasing throughout many regions on the planet, including western North America. High-severity wildfires directly affect soils and vegetation by altering soil hydraulic properties, reducing soil organic matter, exporting carbon and nitrogen, and killing trees and understory vegetation. These impacts can...

Soil Health and the Response of the Soil Microbial Community to Disturbances across Western North America

Creator:: Kersey, Jordan H.
Abstract:: Temperate coniferous forests, such as those that cover vast areas of the western US and Canada, have evolved to depend on cycles of disturbance for succession of species and overall ecosystem maintenance. Many of these forest systems are managed, often for timber production, where disturbances are of anthropogenic origin and...
