Stand development, fire and growth of old-growth and young forests in southwestern Oregon, USA

Creator:: Sensenig, Thomas, Bailey, John D., and Tappeiner, John C.
Abstract:: We studied stand development in three distinct forest types in southwestern Oregon using six stands each in uncut and clear-felled old-growth stands and nearby young stands (18 total). Old-growth stands showed a wide range of tree ages (>300 years) and low tree densities for several centuries; rapid early growth produced...

Dead fuels and understory vegetation six years after a large mixed-severity wildfire in southwest Oregon

Creator:: Nathanson, Amy
Abstract:: Though the mixed-evergreen forests of the Klamath Siskiyous have a long history of large, mixed-severity fires, most research in this region has concentrated on the impacts of high-severity fire. Knowledge of the ecological effects of low- and moderate-severity areas within mixed-severity fires is important because such areas may account for...

Regional variation in stand structure and development in forests of Oregon, Washington, and inland Northern California

Creator:: Reilly, Matthew J. and Spies, Thomas A.
Abstract:: Despite its importance to biodiversity and ecosystem function, patterns and drivers of regional scale variation in forest structure and development are poorly understood. We characterize structural variation, create a hierarchical classification of forest structure, and develop an empirically based framework for conceptualizing structural development from 11,091 plots across 25 million...

Fire-mediated pathways of stand development in Douglas-fir/ western hemlock forests of the Pacific Northwest, USA

Creator:: Tepley, Alan J., Swanson, Frederick J., and Spies, Thomas A.
Abstract:: Forests dominated by Douglas-fir and western hemlock in the Pacific Northwest of the United States have strongly influenced concepts and policy concerning old-growth forest conservation. Despite the attention to their old-growth characteristics, a tendency remains to view their disturbance ecology in relatively simple terms, emphasizing infrequent, stand-replacing (SR) fire and...

Evaluating Multi-objective Trade-offs in Mature Douglas-fir (Pseudotsuga menziesii) Stands of Western Oregon

Creator:: Williams, Neil G.
Abstract:: 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...

Trade-offs between management for fire risk reduction and northern spotted owl habitat protection in the dry conifer forests of southern Oregon

Creator:: Comfort, Emily Julia, 1974-
Abstract:: There is a perceived trade-off between fire risk reduction and northern spotted owl habitat protection in dry-conifer forests in southwestern Oregon. Management options for balancing this trade-off need to be sought at the landscape level. Applied landscape ecology suggests three important features to consider are (1) patch size and configuration...

Contributions of Epicormic Branches and Delayed Adaptive Foliage in Coastal Douglas-fir under Variable Density Management Regimes

Creator:: Punches, John W.
Abstract:: The contribution of delayed adaptive reiteration to crown maintenance was explored across a wide range of adjacent open space conditions in early-mature (approximately 60 year old) Douglas-fir located on the eastern slope of Oregon’s Coast Range. The stands had experienced uniform thinning in 1964-65 and 1980-81 to release dominant and...

Mixed-Severity Fire Effects on Biological Legacies and Vegetation Response in Pseudotsuga Forests of Western Oregon's Central Cascades, USA

Creator:: Dunn, Christopher J.
Abstract:: Mixed-severity fire occurrence is increasingly recognized in Pseudotsuga forests of the Pacific Northwest, but questions remain about how tree mortality varies, and forest structure is altered, across the disturbance gradient observed in these fires. Therefore, we sampled live and dead biological legacies at 45 one ha plots, with four 0.10...

Prevalence and association of depressive symptoms with physical disability and long-term care use among older American Indians

Creator:: Schure, Marc B.
Abstract:: Health officials have recently been sounding the alarm that depression will soon surpass many of the major medical conditions in causing disability among adults. Recent demographic and health trends are generating public health concern about depression. First, the prevalence of chronic conditions has dramatically increased over the last several generations....

Science Review of the Oregon Department of Forestry’s Proposed Species of Concern Strategy and the Board of Forestry’s State Forests Performance Measures

Creator:: Institute for Natural Resources
Abstract:: On behalf of the Board of Forestry (the Board), the Oregon Department of Forestry (ODF) approached the Oregon University System’s (OUS) Institute for Natural Resources (INR) to conduct an independent, outside review of the body of science ODF considered as it evaluated forest management plans and developed the Species of...
