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...
Increased atmospheric carbon emissions of carbon monoxide, carbon dioxide, and methane acerbate climate change through carbon cycle disruption. Riparian areas offer substantial ecosystem services such as water filtration, slowing and cooling, and as is being discovered, a significant carbon sink. Total percent carbon and carbon stocks in restored riparian areas...
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...
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...
In recent times, public policy debates in the United States have been very contentious and dysfunctional. To help improve this situation, a multi-discipline research effort was conducted to look at "solution papers" as a form of public participation. Specifically, the roles of objectivity and mutual respectfulness were under consideration. Foundational...
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...
The purpose of this qualitative case study was to investigate the development of social norms in a fifth-grade reform-based mathematics classroom through a close examination of one teacher's actions during the first three weeks of school. This study offers insights into the following research questions: 1) How does an elementary...
The development of new technologies in science is a balance between existence and use. There are three versions of this duality – something is built and users come, something is built and users don’t come, and, finally, potential users show up but the ballpark has not yet been built. In...
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...
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...
