Contemporary regional forest dynamics in the Pacific Northwest

Creator:: Reilly, Matthew J. (Matthew Justin), 1975-
Abstract:: Recent climatic warming trends and increases in the frequency and extent of wildfires have prompted much concern regarding the potential for rapid change in the structure and function of forested ecosystems around the world. Episodes of mortality in wildfires and insect outbreaks associated with drought have affected large areas and...

Mixed-conifer forests of central Oregon : structure, composition, history of establishment, and growth

Creator:: Merschel, Andrew G.
Abstract:: The structure and composition of mixed-conifer forest (MCF) in central Oregon has been altered by fire exclusion and logging. The resulting increased density, spatial contagion, and loss of fire resistant trees decrease the resiliency of this ecosystem to fire, drought, and insects. The historical and current composition and structure of...

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...

Patterns of tree establishment and vegetation composition in relation to climate and topography of a subalpine meadow landscape, Jefferson Park, Oregon, USA

Creator:: Zald, Harold S. J.
Abstract:: The forest alpine tundra ecotone (FTE, also known as alpine treeline or subalpine parkland), is a conspicuous feature of mountain landscapes throughout the world. Climate change-driven increases in temperature are believed to result in FTE movement and tree invasion of subalpine meadows, which have been documented throughout the Northern Hemisphere...

Effects of canopy gaps in Douglas-fir forests and resource gradients on fecundity and growth of understory herbs

Creator:: St. Pierre, Elizabeth A. (Elizabeth Ann)
Abstract:: Effects of small-scale disturbances on fecundity and growth rates of Linnaea borealis L., Tiarella trifoliata L. var. unifoliata, and Trillium ovatum Pursh. were studied in old-growth forests in the Tsuga heterophylla Zone on the west slope of the Cascade Mountain Range of Oregon. Performance of each species was compared in...

Watershed-scale vegetation patterns in a late-successional forest landscape in the Oregon Coast Range

Creator:: Wimberly, Michael C.
Abstract:: Knowledge about vegetation patterns and ecological processes in unmanaged, late-successional watersheds is needed to provide a foundation for forest management strategies aimed at conserving native biodiversity. I examined influences of environmental variability and disturbance history on forest structure and composition in the Cummins Creek Wilderness, located on the central Oregon...

Disturbance and landscape history as a reference for evaluating forest management effects at a regional scale : examples from the Coast Range of Oregon, USA

Creator:: Nonaka, Etsuko
Abstract:: History is an invaluable source of information to understand and evaluate management influences on contemporary ecosystems and landscapes. The first two chapters (Chapters 2 and 3) explored the concept of historical range of variability (HRV) in landscape structure and stand structure using a stochastic fire simulation model to simulate presettlement...

Plant and amphibian assemblages in zero-order basins in the Oregon Coast Range

Creator:: Sheridan, Chris D.
Abstract:: We have a poor understanding of the biotic communities in zero-order basins, drainages extending from ridgelines to the initiation of first-order streams. This study describes baseline plant and amphibian composition in unmanaged zero-order basins in the Oregon Coast Range. Specifically, I studied: i) the spatial distribution and diversity of species,...

Dead wood dynamics and relationships to biophysical factors, forest history, ownership, and management practices in the Coastal Province of Oregon, USA

Creator:: Kennedy, Rebecca S.H.
Abstract:: Dead wood patterns and dynamics vary with biophysical factors, disturbance history, ownership, and management practices. Through field and modeling studies, I examined the current and potential future amounts of dead wood in two landscapes and region-wide in the Coastal Province of Oregon. The objectives of the first study were to...

Development of two coniferous stands impacted by multiple, partial fires in the Oregon Cascades : establishment history and the spatial patterns of colonizing tree species relative to old-growth remnant trees

Creator:: Goslin, Matthew N.
Abstract:: Trees that survive disturbances can form a prominent legacy which may influence post-disturbance successional pathways. The effects of biological legacies on community dynamics is a critical question in ecology. In the present study, I examined two mapped stands in which old-growth remnant trees, survivors of partial fires, emerge above a...
