Temporal and spatial variability of historic fire frequency in the southern Willamette Valley foothills of Oregon

Creator:: Robbins, Danielle
Abstract:: A crossdated fire history was reconstructed for a 1562 km2 area in the southern Willamette foothills of Oregon, using fire scars and tree origin years from twelve sites. The purpose of this study was to determine fire frequency for each site and to quantify temporal and spatial variability of fire...

Fire ecology and management in plant communities of Malheur National Wildlife Refuge, southeastern Oregon

Creator:: Young, Richard P.
Abstract:: This research assesses prescribed burning as a habitat management technique in wetlands and associated upland communities of Malheur National Wildlife Refuge, southeastern Oregon. Experimental burns were conducted to evaluate fire behavior and effects in wetland and upland habitats, and, fire effects on Cirsium arvense. Wetland plant communities were monotypic stands...

The use of burned forest by breeding birds following the Biscuit Fire in southwest Oregon

Creator:: Donaghy Cannon, Michelle M.
Abstract:: Fire severity is hypothesized as an important driver of bird responses to wildfire. For those species that typically respond negatively to increasing severity, Accessibility of high-severity burned forest may be dependent on the proximity of unburned or low-severity burned forest to meet all of the needs of breeding bird species...

Fire history, fire regimes, and development of forest structure in the central western Oregon Cascades

Creator:: Weisberg, Peter J.
Abstract:: Fire history and fire regimes were reconstructed for a 450 km² area in the central western Oregon Cascades, using tree-ring analysis of fire scars and tree origin years at 137 sampled clearcuts. I described temporal patterns of fire frequency, severity, and size, and interpreted topographic influences on fire frequency and...

The effect of fire regime on coarse woody debris in the west central Cascades, Oregon

Creator:: Wright, Pamela J.
Abstract:: This study examined the effect of fire regime on coarse woody debris (CWD) mass using a combination of field data and modeling. The objectives were to use field sampling to determine how CWD differs between two areas that have had different fire regimes, and investigate how fire frequency and severity,...

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...

Preliminary reconstruction and analysis of change in forest stand age classes of the Oregon Coast Range from 1850 to 1940

Creator:: Teensma, Peter Dominic Adrian, 1956-, Rienstra, John T., and Yeiter, Mark A.
Abstract:: Fire and other catastrophic disturbance events in the Douglas-fir forests of the Oregon Coast Range have been significant in determining the distribution of stand age classes and, hence, habitat. Except for the past half century, knowledge of fire in the region has largely been local and anecdotal. The Douglas-fir forests...

Fire severity and vegetation response to fire in riparian areas of the Biscuit and B&B Complex Fires, Oregon

Creator:: Halofsky, Jessica E.
Abstract:: Fire is the dominant disturbance process in western U.S. forests, and although effects of fire in upland forests are relatively well-studied, there is little information about fire effects on riparian forests, critical areas of the landscape for both habitat and water quality. This dissertation examines different aspects of fire effects...

Forest vegetation and fuel dynamics following stand-replacing wildfire, re-burn, and postfire management in the Siskiyou Mountains, Oregon

Creator:: Donato, Daniel C.
Abstract:: Following high-severity fire, forest succession may take alternate pathways depending on the pattern of the fire and any secondary disturbances during early stand development, with lasting consequences for ecosystem function. The objectives of this research were to quantify: (1) early postfire regeneration as influenced by the spatial pattern of a...
