Analysis of the regional carbon balance of Pacific Northwest forests under changing climate, disturbance, and management for bioenergy

Creator:: Hudiburg, Tara W.
Abstract:: Atmospheric carbon dioxide levels have been steadily increasing from anthropogenic energy production, development and use. Carbon cycling in the terrestrial biosphere, particularly forest ecosystems, has an important role in regulating atmospheric concentrations of carbon dioxide. US West coast forest management policies are being developed to implement forest bioenergy production while...

Forest Response to Water Availability and Disturbance in the Western United States

Creator:: Berner, Logan T.
Abstract:: Earth’s atmosphere is unequivocally warming due to CO₂ and other greenhouse gas (GHG) emissions from human activities and this is having widespread impacts on forest ecosystems that provide important services to human societies. Forest ecosystems help regulate atmospheric CO2 concentrations by sequestering carbon in tree biomass and soils, which is...

Vertical structure and aboveground biomass of tropical forests from lidar remote sensing

Creator:: Gonçalves, Fabio Guimarães
Abstract:: Methods for obtaining accurate, spatially explicit estimates of biomass density in tropical forests are required to reduce uncertainties in the global carbon cycle, and to support international climate agreements and emerging carbon markets. Three-dimensional (3-D) remote sensing techniques sensitive to the vertical structure of vegetation provide a unique opportunity for...

Forest vegetation and fuel dynamics following stand-replacing wildfire, re-burn, and postfire management in the Siskiyou Mountains, Oregon

Creator:: Donato, Daniel C.
Abstract:: Following high-severity fire, forest succession may take alternate pathways depending on the pattern of the fire and any secondary disturbances during early stand development, with lasting consequences for ecosystem function. The objectives of this research were to quantify: (1) early postfire regeneration as influenced by the spatial pattern of a...

Remote sensing of radiation intercepted by vegetation to estimate aboveground net primary production across western Oregon

Creator:: Law, Beverly E.
Abstract:: Remote sensing of variables necessary to estimate net primary production of vegetation over large temporal and spatial scales has been a goal of climate change research. This thesis consists of two studies that address the reliability of satellite and airborne sensors to quantify a basic component of all production models,...

Carbon fluxes across three climatically-distinct forest chronosequences in Oregon

Creator:: Campbell, John
Abstract:: Biometric and gas exchange techniques were used to measure soil respiration (soil surface CO₂ efflux) and NEP (Net Ecosystem Production) across three climatically-distinct forest chronosequences in Oregon. Results indicate significant forest type, age, and forest type x age interaction effects on annual soil respiration. A regional age class distribution skewed...

Detection of deforestation and land conversion and estimation of atmosperic emissions and elemental pool losses from biomass burning in Rondônia, Brazil

Creator:: Guild, Liane S.
Abstract:: Biomass burning associated with deforestation and land use in the Amazon, greatly contributes to emissions as well as depletion of elemental pools. We identified deforestation and pasture formation and quantified resultant burning emissions and terrestrial aboveground elemental pool losses during a period of early colonization in the vicinity of Jamari,...

Carbon Stocks and Soil Greenhouse Gas Emissions Associated with Forest Conversion to Oil Palm Plantations in Tanjung Puting Tropical Peatlands, Indonesia

Creator:: Novita, Nisa
Abstract:: This dissertation addresses gaps of knowledge associated with how ecosystem carbon stocks and greenhouse gas emissions are affected by land use land cover change in tropical peatlands. This was the first study that paired peat swamp forests with oil palm plantations and analyzed site scale variation on greenhouse gas emissions....

Modeling Forest Response to Changing Climate Conditions in Western North America

Creator:: Hawkins, Linnia R.
Abstract:: Forests play an integral role in the global carbon cycle, regulating the atmospheric CO₂ concentration by sequestering nearly one third of anthropogenic carbon emissions and storing carbon for centuries. Forest ecosystems are integrated into the culture, ecology, and economy of western North America, supporting wildlife habitat, local economies, recreation, and...

School-community collaboration as a strategy for meeting the needs of at-risk youth : a case study of selected youth services teams

Creator:: Hobbs, Beverly B.
Abstract:: The purpose of this study was to explore and describe the nature of local school-community human service agency collaboration undertaken to address the needs of at-risk youth. The study focused on the experience of four youth services teams in two Oregon counties. A qualitative, multiple-case study approach was used as...
