By affecting the ecological, pecuniary and aesthetic productivity of ecosystems, invasive species (IS) increase production and management costs to business, while straining public agencies' budgets with monitoring, enforcement and management efforts. Understanding invasion pathways or vectors, and identifying costs and benefits of alternative management strategies are critical to public and...
Contemporary forest management involves a more extensive and diverse suite of management objectives than was the case throughout much of the Twentieth Century. Heightened public and political awareness of local and global biodiversity decline, and interest in arresting these trends, has increased the emphasis on broad-based biodiversity conservation as an...
Coastal communities in the U.S. Pacific Northwest (PNW) are rapidly engaging with the idea that hazards and environmental pressures are changing and may be characteristically different in the near future. This has led to a need for scientific knowledge and tools that can help coastal communities prepare and build resilience...
Estimates of potential carbon (C) storage can be used to constrain predictions of future carbon sequestration and to understand the degree to which disturbances, both natural aid anthropogenic, affect C storage. An upper bound on C storage in the Pacific Northwest (PNW) of the United States was estimated using field...
The purpose of this study was to understand the lived experience of students to discern the impact of their interaction with the food pantry. This knowledge may, in turn, influence future food pantry methods and wider policy, both at PNW College and more broadly. Not only does student hunger have...
Relative to other systems in the PNW, the rain-dominated, coastal watersheds of western Oregon have shallow aquifers. Given the seasonality of streamflow and storage limitations in coastal, rain-dominated watersheds, changes in the temporal patterns of precipitation have the potential to magnify the risk of extreme streamflow conditions during both high-...
The forest sector forms an important part of Oregon’s economy, especially in rural communities. However, the economic performance and development of the sector are subject to both significant natural disturbances and to new and existing policies. The most common and disastrous natural disturbances in Oregon are wildfires. The Biscuit Fire...
Many important policy problems entail linkages among multiple economic sectors, and require the use of a general equilibrium economic modeling framework. This economic approach is appropriate when the market for any one good or service is linked to numerous other goods and services, and back to fundamental inputs such as...
I focus on addressing knowledge gaps relating to management of cryptogams in Oregon's public lands in Pseudotsuga menziesii-Tsuga heterophylla forests on the west side of the Cascade Range and dryland steppe in the Cascade Range's rainshadow.
While a great deal of research has illustrated the importance of late-successional forests for...
Relatively recent increases in ponderosa pine abundance have effected unprecedented changes to ecosystem structure and function. Efforts to restore ponderosa pine systems are often focused on the manipulation of tree structure and the re-introduction of a more natural fire regime. Successful restoration should also incorporate understory components but information addressing...
