Ecosystem process models are important tools for determining the interactive effects of global change and disturbance on forest carbon dynamics. Here we evaluated and improved terrestrial carbon cycling simulated by the Community Land Model (CLM4), the land model portion of the Community Earth System Model (CESM1.0.4). Our analysis was conducted...
There are currently more than 580 natural areas in Oregon and Washington managed by 20 federal, state, local, and private agencies and organizations. The natural areas network is unparalleled in its representation of diverse ecosystems found in the region and may be an excellent collection of sites for monitoring long-term...
Wetlands are productive ecosystems providing many ecosystem services. Many regulatory agencies recognize the need to protect and preserve wetlands. However, some impacts may be unavoidable. Under those circumstances, compensatory wetland mitigation may be necessary to offset adverse impacts to wetlands. The U.S. Army Corps of Engineers and the New York...
The Upper Klamath Basin is an ecologically significant watershed that supports millions of migratory waterbirds along the Pacific Flyway in addition to an agricultural economy and a tribal fishery. This literature review and annotated bibliography is the basis for a capstone project to address the history, evolution, impacts, and responses...
Spotted lanternfly (Lycorma delicatula) is an invasive insect that was first discovered in Pennsylvania in 2014, and has since spread across the Northeastern United States. States in the Northeast have created quarantine zones, regulations, outreach, reporting systems, and management efforts for the control of spotted lanternfly. Despite states’ efforts, spotted...
Native, wild bee populations play an important functional role in terrestrial ecosystems through pollination services. In recent years, increased attention has been paid to the importance of bumble bee species and their contribution to the agricultural economy, in large part because of the widespread losses of populations across landscapes, both...
Non-timber forest products (NTFPs) have an extensive history of harvest in the United States. The Pacific Northwest is well-reputed as a major source of floral greens for international markets. One NTFP in particular, beargrass (Xerophyllum tenax), has been repeatedly identified as a prominent, high-value species in the floral greens industry...
Each NWR within the U.S. Fish and Wildlife Service (FWS) National Wildlife Refuge System (NWRS) provides landscapes that contribute to conservation of wildlife and the habitats they depend on at local, regional, and national levels. The Integrated Pest Management Plan (IPMP) for a given refuge is a guide to how...
This capstone report provides an overview of the emergence of the bigleaf maple sugaring industry in Oregon. This report consists of a literature review and three case studies. The literature review compiles information relevant to bigleaf maple sugaring within the wider context of maple sugaring in North America. The three...
The intensity and scale of wildfires has increased throughout the Pacific Northwest in recent decades, especially within the last decade, destroying vast amounts of valuable resources and assets. This trend is predicted to remain or even magnify due climate change, growing population, increased housing density. Furthermore, the associated stress of...
