Monitoring for Ozone Injury in West Coast (Oregon, Washington, California) Forests in 1998

Creator:: Campbell, Sally J., Smith, Gretchen, Temple, Pat, Pronos, John, Rochefort, Regina, and Andersen, Chris
Abstract:: In 1998, forest vegetation was monitored for ozone injury on permanent plots in two Sierra Nevada national forests in California, at three locations in Mount Rainier National Park in Washington, and at 68 forest health monitoring (FHM) locations throughout Washington, Oregon, and California. This was the first year that extensive...

Mount Mazama and Crater Lake : A Study of the Botanical and Human Responses to a Geologic Event

Creator:: Green, Robyn A.
Abstract:: Crater Lake, located in the southern Cascade mountains of Oregon, is the seventh deepest lake in the world. Unlike a majority of the deepest lakes in the world, found in continental rift valleys, Crater Lake is in the caldera of a volcano. For the young at heart and mind, those...

Effects of wildfire burn severity on soil microbial communitiesand invasive plant species in the Cascade Range of Oregon

Creator:: Hebel, Cassie L.
Abstract:: Fire suppression in the last several decades has resulted in unprecedented accumulations of organic matter on the landscape, leading to an increase in large, intense wildfires. This study investigated the soil microbial community (using phospholipid fatty acid analysis) across recently burned forests on the eastern slope of the Cascade Range...

Phytoplankton shading of marine benthic macrophytes: Implications for intertidal community structure

Creator:: Kavanaugh, Maria T.
Abstract:: Previous observations of light levels and phytoplankton abundances along the Oregon coast demonstrated that phytoplankton attenuated light sufficiently to potentially limit the growth of intertidal macrophytes and therefore structure local intertidal communities. Inspired by this observation, in spring 2004, I initiated a study to quantify the direct and indirect benthic...

Floodplain vegetation following over 80 years of intensive land use and de-watering : Lower Owens River, California

Creator:: Risso, Derek A.
Abstract:: Riparian areas in the arid western United States are critical ecosystems that have been severely degraded by a variety of land and water uses over the last 100 years. In this study, the composition and structure of floodplain vegetation along the Lower Owens River in eastern California was quantitatively described...

Interactive influences of wildfire and nonnative species on plant community succession in Hawaii Volcanoes National Park

Creator:: Ainsworth, Alison
Abstract:: The role of fire as a natural disturbance, its interactions with nonnative species and effects of repeated fires in the Hawaiian Islands have received little investigation. We are unsure of the role fire played in shaping forest structure and composition as well as affecting evolutionary processes of the native biota....

Mapping vegetation using landsat TM and ETM+ in Eritrea

Creator:: Iyob, Biniam
Abstract:: The objective of this study was to examine vegetation and vegetation change in Eritrea over a period from the mid 1980s to 2002 using satellite remote sensing, and relate observed changes to the recent history of drought and war in the region. Specific objectives were (1) to examine vegetation change...

Testing the correlation between inundation period and coastal wetland productivity in Carex lyngbyei and Distichlis spicata communities, South Slough National Estuarine Reserve, Oregon

Creator:: Gilman, Eric
Abstract:: I tested the hypothesis that there is a correlation between inundation period and net primary production (NPP) in estuarine salt marshes through an observational experiment at South Slough National Estuarine Reserve, Oregon. I estimated primary production and inundation period for selected monotypic plant communities in (1) a naturally restored wetland...

Evaluating the effectiveness of commonly used herbaceous weed control regimes in a Pacific Northwest conifer plantation

Creator:: Dinger, Eric
Abstract:: Early in the establishment of Pacific Northwest conifer plantations, herbaceous weeds often decrease seedling growth through competition for soil moisture during the dry summer months. Critical period studies have reported that reductions in competitive weed cover are necessary during the initial years of establishment to avoid reductions in seedling growth....

Belowground carbon storage and soil organic matter quality following fertilizer and herbicide applications in ponderosa pine plantations along a site-quality gradient in northern California

Creator:: McFarlane, Karis J., 1979-
Abstract:: Belowground carbon (C) storage and quality of soil organic matter (SOM) in forest soils have implications for sustainable forest management and C sequestration, but how these pools change in response to management is poorly understood. I investigated whether fertilization and competing vegetation control, applied alone or in combination early in...
