Long-term Effects of Vegetation Management on Biomass Stock and Aboveground Net Primary Productivity of Four Coniferous Species in the PNW

Creator:: Flamenco, Herman N., Jr.
Abstract:: Forest vegetation management (FVM) is an important component of reforestation in the Pacific Northwest (PNW). Several studies have demonstrated the benefits of vegetation management on planted conifer growth and survival. However, few reports have been published on the long-term effects of FVM treatments on total ecosystem biomass accumulation and aboveground...

Phylogenetic Identification of Pathogenic and Endophytic Fungal Populations in West Coast Douglas-fir (Pseudotsuga menziesii) Foliage

Creator:: Daniels, Hazel A.
Abstract:: Douglas-fir provides social, economic, and ecological benefits in the Pacific Northwest (PNW). In addition to timber, forests support abundant plant and animal biodiversity and provide socioeconomic viability for many rural communities. Products derived from Douglas-fir account for approximately 17% of the U.S. lumber output with an estimated value of $1.9...

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...

Assessing Mechanisms of Douglas-fir Growth Response to Operational Nitrogen Fertilization in Western Oregon

Creator:: Putney, Jacob D.
Abstract:: Nitrogen (N) fertilizer is a commonly applied silvicultural treatment in intensively managed Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] plantations. When attempting to maximize average growth responses through fertilization, landowners experience difficulty prioritizing stands for treatment based on the likely magnitude of response and return on the operational investment. Field trials were...

Estimation of surface canopy water in Pacific Northwest forests by fusing radar, lidar, and climatic data

Creator:: Heffernan, Scott A.
Abstract:: Surface Canopy Water (SCW) is the intercepted rain water that resides within the tree canopy and plays a significant role in the hydrological cycle. Challenges arise in measuring SCW in remote areas using traditional ground based techniques. Remote sensing in the radio spectrum has the potential to overcome the challenges...

Full Text:: constant cloud cover, such as those in Pacific North West (PNW), can be investigated remotely

Transformation of Western Hemlock Tree Crowns by Dwarf Mistletoe

Creator:: Calkins, Stephen J.
Abstract:: Hemlock dwarf mistletoe (Arceuthobium tsugense subsp. tsugense) is an arboreal, hemiparasitic plant that principally parasitizes western hemlock (Tsuga heterophylla). Hemlock dwarf mistletoe exerts a profound influence on infected trees that can drastically change the structure of the tree crown due to reduced growth, top dieback, branch deformation and death, resulting...

Diel Rest Structure Selection and Multiscale Analysis of Pacific Marten Resting Habitat in Lassen National Forest, California

Creator:: Tweedy, Patrick J.
Abstract:: Forests in the western United States have changed drastically over the past 150 years given a long history of utilization (harvest and grazing) and associated fire exclusion. These actions have altered the composition and structure of these forests as well as affected ecosystem function. Current policies for federal land management...

Estimation of leaf area index and simulation of evapotranspiration for intensively managed Douglas-fir forests

Creator:: Rogers, Nicole S.
Abstract:: Understanding the tradeoff between water use and productivity is critical for modeling growth of intensively managed Douglas-fir forests in the Pacific Northwest. Evapotranspiration is closely linked to carbon dioxide intake during the process of photosynthesis. However, summer drought characterizing the growing season in this region imposes a limit on carbon...

Bridging Ways of Knowing to Model the Dynamics of Fire as an Ecocultural Process on Frequent Fire Landscapes of the Pacific Northwest

Creator:: Greenler, Skye M.
Abstract:: Wildfire impacts have intensified in many ecosystems across the western United States due to the combined impact of fire exclusion, climate change, and land management practices. However, on many of these landscapes, fire is a fundamental ecological process that has shaped vegetation structural and compositional diversity, ecosystem function, landscape pattern,...

An Analysis of Oregon’s Preferential Forest Property Tax Programs in Relation to Non-industrial Private Forest Landowners’ Tax Program Enrollment Decisions and Forest Management Behavior

Creator:: Rushakoff, Benjamin J.
Abstract:: Little is known about non-industrial private forestland (NIPF) owners in relation to Oregon’s two primary preferential forest property tax programs: Forestland Program – the default tax program for many forestland owners, and Small Tract Forestland Option (STF) – a voluntary program wherein landowners pay reduced annual property taxes and an...
