Addressing Emerging Issues in Tropical Ecohydrology : A Combined Hydrometric and Isotopic Approach to Evaluate the Origin and Age of Water in a High-Elevation Tropical Ecosystem

Creator:: Mosquera, Giovanny M.
Abstract:: This thesis focuses on the identification of ecohydrological processes in nested system of catchments in a tropical alpine (the wet Andean páramo) ecosystem. We accomplish this by conducting a water stable isotopic characterization of water sources, an evaluation of the mean transit time (MTT) of streams waters, and the investigation...

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 Development and Organic Carbon Stocks Across a Lithosequence in the Perhumid Coastal Temperate Rainforests of Southeast Alaska

Creator:: Fedenko, Jennifer M.
Abstract:: The perhumid coastal temperate rainforests of southeast Alaska contain an abundance of soil organic carbon (SOC) that has accumulated in a wet, cool climate where forest fire disturbance is minimal and organic matter decomposition rates are low. Coastal temperate rainforests are supported by carbon-rich soils that provide ecosystem services including...

Demography, home range, and habitat selection of northern spotted owls in the Ashland Watershed

Creator:: Schilling, Jason W.
Abstract:: Northern Spotted Owls (Strix occidentalis caurina) inhabit productive forests that historically supported frequent, large, variable-severity fires in the Klamath province of southwestern Oregon occur in complex. The potential for high-severity wildfire remains high throughout this region, so remaining spotted owl habitat is at risk. An adaptive management approach to fire...

Forest Successional and Disturbance Dynamics in the Southern Blue Mountains of Eastern Oregon

Creator:: Johnston, James D.
Abstract:: The application of modern land management practices beginning at the turn of the 20th century is widely believed to have dramatically transformed forest landscapes of the inland Pacific Northwest. Restoring historical conditions to make forests resilient to future climate and disturbance regimes is a major goal of federal forest managers....

The effects of forest fuel reduction on fire severity and long-term carbon storage

Creator:: Mitchell, Stephen Richard
Abstract:: Two forest management objectives being debated in the context of federally managed landscapes in the US Pacific Northwest involve a perceived trade-off between fire restoration and C sequestration. The former strategy would reduce fuel (and therefore C) that has accumulated through a century of fire suppression and exclusion that has...

Beetle Outbreaks and Wildfires: Drivers of Fire Severity, Recruitment, and Structural Legacies for Sub-boreal Forests in British Columbia

Creator:: Talucci, Anna C.
Abstract:: Bark beetle outbreaks have left a legacy of tree mortality across fire-prone landscapes of western North America that could influence how these forests will burn and regenerate. While research has been focused on forests in the western United States, the potential interactions between mountain pine beetle (MPB) outbreaks and wildfires...

Social Acceptance of Landscape-Scale Restoration : Treatment of Riparian Areas in the Lower Joseph Creek Watershed, Oregon.

Creator:: Kohler, Gabriel E.
Abstract:: Managing riparian areas in the dry forests of the intermountain west for diverse public values can create conflict, potentially limiting social acceptance in landscape-scale restoration projects. This thesis examined accelerated landscape-scale restoration as part of a broader shift toward ecosystem management on national forestland, which incorporates social values into forest...

Understanding Public Perceptions of Post-Wildfire Landscape Recovery

Creator:: Kooistra, Chad M.
Abstract:: Forest disturbances, such as wildfires, pine beetle outbreaks, and floods are important features of many landscapes and ecosystems. Many disturbances are increasing in size, frequency, and intensity due to changing climates and land management decisions. The changing ecological and aesthetic conditions following a disturbance can lead to negative short- and...

Forest Fire Effects on Radiative and Turbulent Fluxes over Snow : Implications for Snow Hydrology

Creator:: Gleason, Kelly E.
Abstract:: As a result of a warming climate, subsequent declining snowpack, and a century of fire suppression, forest fires are increasing across the western United States. However, we still do not fully understand how forest fire effects snowpack energy balance, nor the volume and availability of snow melt and associated water...
