Examination of imputation methods to estimate status and change of forest attributes from paneled inventory data

Creator:: Eskelson, Bianca N. I.
Abstract:: The Forest Inventory and Analysis (FIA) program conducts an annual inventory throughout the United States. In the western United States, 10% of all plots (one panel) are measured annually, and a moving average is used for estimating current condition and change of forest attributes while alternative methods are sought in...

Effect of plant date on subsequent seedling field performance

Creator:: Taylor, Michael Monroe
Abstract:: Douglas-fir (Psudotsuga menziesii (Mirb.) Franco) seedlings were outplanted on eight dates (every three weeks from mid-August 2005 through mid-January 2006). On each plant date, seedlings from a conventional dormancy (CONV) induction treatment, including moisture and nutrient stress, and a shortened daylength (SD) treatment were outplanted on three western Oregon sites...

Optimal timber harvesting in uneven-aged forest stands : a discrete-time optimal-control approach

Creator:: Haight, Robert G.
Abstract:: The purpose of this dissertation is to formulate, analyze and numerically solve the dynamic harvesting problem for uneven-aged stands. The problem is to find the optimal numbers of trees to remove from diameter classes over a finite time horizon and is formulated as a discrete-time optimal-control problem with bounded control...

Influence of geomorphology and land use on distribution and abundance of salmonids in a coastal Oregon basin

Creator:: Schwartz, John Steven
Resource Type:: Masters Thesis
Full Text:: project. Thanks are due to Dr. Bob Beschta, Dr. James Hall, and Dr. David Hann for serving on my graduate

Maritime windstorm influence on soil process in a temperate rainforest

Creator:: Kramer, Marc G.
Abstract:: Maritime cyclonic windstorms cause widespread disturbance to forested ecosystems in southeast Alaska. The consequence of this disturbance process on the movement, storage, and quality of soil carbon, forest hydrology and streamwater chemistry was studied along a windthrow disturbance sequence. Soil profiles were described and the thickness of the major organic...

Similarity inheritance : a model of inheritance for declarative visual programming languages

Creator:: Djang, Rebecca W. (Rebecca Walpole)
Abstract:: Declarative visual programming languages (VPLs), including spreadsheets, make up a large portion of both research and commercial VPLs. Spreadsheets in particular enjoy a wide audience, including end users. Unfortunately, spreadsheets and most other declarative VPLs still suffer from some of the problems that have been solved in other languages, such...

Characteristics of soil organic matter in two forest soils

Creator:: Crow, Susan E.
Abstract:: Soil organic matter (SOM) is the terrestrial biosphere's largest pool of organic carbon (C) and is an integral part of C cycling globally. Soil organic matter composition typically can be traced directly back to the type of detrital inputs; however, the stabilization of SOM results as a combination of chemical...

Response of arthropods to different intensities of thinning in Oregon

Creator:: Yi, Hoonbok
Abstract:: The process of silvicultural thinning has become very controversial recently with regards to fire protection and management for old-growth conditions and biodiversity. Therefore, an unthinned control stand and 3 different thinning intensities were examined for their effects on the abundance, species richness, and diversity of arthropods in thinning treatments of...

Mechanical behavior of coniferous trees subjected to wind loading

Creator:: Moore, John R.
Abstract:: The behavior of coniferous trees subjected to wind loading was investigated through a series of experiments and also through simulation modeling. Previous studies that measured the natural oscillation frequencies and damping ratios were reviewed and equations were developed for predicting the natural frequency of a tree from the ratio of...

Divergent Paths to Health: A Comparative Study of the Affordable Care Act’s Medicaid Expansion in California and Non-Expansion in Texas Through the Lens of Policy Diffusion

Creator:: Aguigam, Lyric T.
Abstract:: The enactment of the Patient Protection Affordable Care Act (ACA) in 2010 marked a critical moment in American healthcare history. The ACA introduced Medicaid expansion, a policy designed to extend healthcare coverage to a larger population of low-income Americans. This policy quickly became a topic of debate and led to...
