Effect of Root and Shoot Manipulation on the Morphology and Physiology of Oregon White Oak (Quercus garryana) Seedlings in the Nursery and Following Outplanting

Creator:: Baumgart, Erin E.
Abstract:: Oregon white oak, or Garry oak (Quercus garryana), has been adversely affected by land-use conversion, landscape fragmentation, and anthropogenic fire suppression. Its historical range has contracted significantly to the point where an estimated 1-5% remains intact. Natural regeneration is difficult due to a lack of seed sources and the physiological...

Addressing Seedling Production Challenges for Hispaniolan Pine and Snowberry

Creator:: St. John, Christina M.
Abstract:: The use of native plants in restoration and afforestation has increased worldwide as their benefits to habitat quality, ecosystem services and local community well-being become widely known. In many restoration and afforestation sites, the most cost-effective and efficient way to establish plants is to use seedlings. Unfortunately, there is a...

Using remote sensing, in situ observations, and geographic information systems to map benthic habitats at Heceta Bank, Oregon

Creator:: Whitmire, Curt E.
Abstract:: Dramatic declines in many species of demersal fishes off the West Coast have resulted in the designation of nine commercially important species as being overfished. While the causes of those declines are not clearly understood, the fact remains that a paucity of life history and abundance data exists for many...

Harnessing the power of Google Earth for seagrass conservation in the Comoros Islands

Creator:: Reifke, Lisa M.
Abstract:: Google Earth has given internet users the power of a virtual globe at their fingertips. It is a free, easy to use tool that avoids the need for technical training, and uses a simple, intuitive interface. For this reason, Google Earth appeals to general and more specialized users. This project...

Meadow classification in the Willamette National Forest and conifer encroachment patterns in the Chucksney-Grasshopper meadow complex, Western Cascade Range, Oregon

Creator:: Dailey, Michele Meadows
Abstract:: This study delineates and characterizes the distribution of montane meadows in the Willamette National Forest, identifies encroachment patterns in relation to topographic features and proximity to trees in the Chucksney-Grasshopper meadow complex, and examines tree species and age distributions in relation to distance from forest edges or isolated tree clusters...

Automation and Evaluation of Graduated Dot Maps

Creator:: Arnold, Nicholas D.
Abstract:: Dot mapping is a traditional method for visualizing quantitative data, but current automateddot mapping techniques are limited. The most common automated method places dotspseudo-randomly within enumeration areas, which can result in overlapping dots and verydense dot clusters for areas with large values. These issues affect users’ ability to estimatevalues. Graduated...

Modeling the Environmental Protection Agency's level IV ecoregions within the Klamath Mountains of southern Oregon and northern California

Creator:: Zanger, Christopher
Abstract:: Ecoregions are regions of relative homogeneity with respect to specific ecosystem variables (Bailey 1976; Omernik 1995). There has been an increasing awareness that effective management of environmental resources must be undertaken with an ecosystem perspective (Omernik, 1995). Ecoregions serve as a spatial framework for assessing, managing, and monitoring ecosystems that...

Ghosts of the Gold Rush: Archaeological Investigations at Feature 96 in the Klondike Gold Rush National Historic Park, Dyea, Alaska (49SKG-006)

Creator:: Diederich, Matthew J.
Abstract:: This thesis deals with the archaeological investigations of an 1897-1898 gold rush structure in the town of Dyea, Alaska. Little is known about this structure (Feature 96) from the historical records. A three year project was conducted to investigate Feature 96 in order to determine the function of the structure,...

Sensitivity analysis of the Catchment Modeling Framework (CMF) and use in evaluating two agricultural management scenarios

Creator:: Metta, John W. P.
Abstract:: Abstract Watershed-scale fate/transport modeling of contaminants is a tool that scientists and land managers can use to assess pesticide contamination to stream systems. The Catchment Modeling Framework (CMF) is a catchment-scale fate/transport modeling tool. It was developed to help scientists and land managers assess the effects of possible land-use decisions...

A mathematical transformation of multi-angular remote sensing data for the study of vegetation change

Creator:: Friedel, Robert G.
Abstract:: Vegetation change is an important factor affecting the global carbon cycle, land-atmosphere interaction, and terrestrial ecology. The study of vegetation change on a global scale can be used to evaluate the impact of global climate change on terrestrial ecosystems. Satellite remote sensing can monitor vegetation change at the global scale,...
