The mobility and fate of phosphorus following municipal biosolids application to forest soils
(1999)Municipal biosolids are typically not used on the steepest of forested slopes in the Pacific Northwest. The primary issue in using biosolids on steep slopes is movement of constituents in biosolids to surface waters during ... -
Modeling habitat suitability of Pinus densiflora in response to climate change in the Korean peninsula and East Asia
(2013-02-25)The current and future climate suitability of Pinus densiflora in the Korean peninsula, Japan Isles, and parts of northen China was modeled using Random Forest predictors. Pinus densiflora is among the tree species with ... -
Modeling large-scale fire effects: concepts and applications
(1998)Climatic changes anticipated for the next century are expected to alter the effects of fire on large-scale vegetation patterns. It is unlikely that future interactions between fire and vegetation can be predicted from ... -
Modeling uncertainty in burn severity using the Composite Burn Index and remotely sensed data
Methods to link ground-based measurements of burn severity with remotely sensed data vary, and there is no consensus on the best approach. The objectives of this dissertation were to: 1) summarize methodological pathways ... -
Morphological, growth, and photosynthetic responses of cottonwood hybrid 47-174 (Populus trichocarpa x P. deltoides) to nitrogen fertilization and leaf rust infection
(2013-02-25)The growth, morphological, and photosynthetic responses of cottonwood hybrid 47-174 to nitrogen (N) stress and leaf rust stress and their interaction are summarized herein. High nitrogen (HN) fertilization enhanced ... -
Mortality Modeling in Douglas-fir Plantations in the Pacific Northwest
Forest management is dynamic and complex, with numerous factors affecting forest development and outcomes of management decisions. In plantation forestry, forest development is typically expected to follow well understood ... -
Motivational Goals of Seattle Homeowners Related to Their Yards: Implications for Ecosystem Service Assessments and Behavioral Appeals
Nearly half of the land areas of many U.S. cities is zoned for single family residences (e.g., 49% of Seattle). These are fragmented management landscapes -- large numbers of parcels are individually managed yet collectively ... -
Multi-scale Analysis of Fire Effects in Alpine Treeline Ecotones
Although the direct effects of climate change have been studied though observational and experimental methods in alpine treeline ecotones (ATEs), indirect effects due to shifts in disturbance regimes have received less ... -
Multilevel planning in forestry
(2003)This dissertation is a study of multilevel planning in forestry. Two models are investigated, the holistic model and the compromise model. A sample problem is formulated to demonstrate each model. The holistic model ... -
Multiple Regression Inference of Yield for Douglas-fir Plantations in the Pacific Northwest
(2013-02-25)Multiple regressions were formulated with predictor variables of latitude, longitude, and elevation, stand stocking, age, and site index for western Oregon, western Washington, and southwest British Columbia. Models were ... -
Multiscale Manipulation of Nanocellulose Structures for Divers Sustainable Materials
Global dependence on petroleum, a finite source, is creating economic, social, and environmental unrest. The quickly depleting limited resource needs a sustainable alternative that can offer the same multifunctional ... -
Mycorrhizal fungus communities of Douglas-fir (Pseudotsuga menziesii) seedlings and trees: effects of proximity to residual trees
(2004)The influence of mature Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) trees in partially harvested stands on seedling growth and colonization by ectomycorrhizal fungi (EMF) is not well understood. To investigate this, ... -
Nanocellulose design; characterizing ammonium persulfate oxidation of wood and a non-wood agricultural residual, Humulus lupulus, bine from the Yakima valley.
Low-density biomass resources such as Humulus lupulus are handicapped by high transportation costs due to widely distributed – low-density acreage and the need for densification of the biomass. Life Cycle Assessment aims ... -
Nanocellulose production from low-cost agricultural residues: process development, economic assessment, and process robustness
The 21st century has been marked by the transition from a petroleum-based economy to a more renewable and sustainable era. Nanocellulose is a plant-based material and an excellent alternative for petroleum-based materials ... -
Nanomaterials for Sustainable Water Remediation
Ever increasing industrialization leads to a rise in contaminated water resources due to the release of pollutants, such as organic dyes, into aquatic environments. Adsorption process, which involves the transfer of ... -
National to local: a pre & post assessment of the Fuel Characteristic Classification System (FCCS) landscape variables for the Confederated Salish and Kootenai Tribes
(2013-02-25)A modified Fuel Characteristic and Classification System (FCCS) fuelbed was created for the Confederated Salish & Kootenai Tribes (CSKT) of Montana. This crosswalk of data combined two principal sources of data: (1) locally ... -
Native solitary bee health in western Washington
Bees are a vital part of the terrestrial ecosystem, providing pollination services to plants and contributing to biodiversity. Spring-emerging solitary native bees face numerous challenges to survival, including inclement ... -
Nature contact and psychological well-being in adults
There is growing evidence that contact with natural environments is associated with a multitude of human health benefits including improved mental health and psychological well-being. However, key gaps in the literature ... -
A New Look at the Quantities and Volumes of Instream Wood in Forested Basins within Washington State
(University of Washington, 2001)Instream wood is recognized as an important feature linked to channel processes that benefit salmonids. Stream channel assessments and restoration/enhancement efforts often associate salmon habitat quality with the quantity ... -
Nitrate in Forest Soils Following Biosolids Applications in a Working Plantation
Biosolids applications to commercial tree plantations is standard practice in the Pacific Northwest. It has shown to increase stand growth, improve the quality of forest soils, soil and above ground carbon sequestration ...
