Empirical Analysis of Processes Affecting Drainage Flows and Inversions in a Forested Mountain Landscape

Creator:: Malek, Ali
Abstract:: The objective of this dissertation was to understand the physical mechanisms affecting inversion events in a complex forested mountain landscape. This work was motivated by the long-term studies of climate at the Andrews Forest, short-term studies of vertical temperature, light, wind, and moisture gradient in old-growth trees, and interest in...

Habitat quality and biotic integrity in mountain streams of East Maui, Hawaii

Creator:: Carter, H. Jamieson
Abstract:: Hawaiian streams are valued for environmental, cultural, and aesthetic qualities. Windward streams in East Maui, Hawaii are diverted to irrigate crops in central portions of the island. Diversions typically remove 100% of the base flow and leave downstream reaches dry most of the year. Ground water seeps and springs contribute...

Influence of spatial and temporal factors on plants, pollinators and plant-pollinator interactions in montane meadows of the western Cascades Range

Creator:: Pfeiffer, Vera W.
Abstract:: Montane meadows comprise less than 5% of the landscape of the western Cascades of Oregon, but they provide habitat for diverse species of plants and pollinators. Little is known about plant-pollinator network structure at these sites. This study quantified plant-pollinator interactions over the summer of 2011, based on six observations...

Forest harvest patterns on private land in western Oregon from 1972 to 2002

Creator:: VanNatta, Lisa R.
Abstract:: This project examined the harvest patterns found on private forestland in western Oregon (46000 1cm2) between 1972 and 2002. The research addressed hypotheses concerning the behaviors of different classes of owners as defined by total amount of forestland owned. Existing forest stand disturbance data and ownership data were combined using...

Climatic and physiographic controls on peakflow generation in the western Cascades, Oregon

Creator:: Perkins, Reed
Abstract:: Despite the importance of rain and snowmelt in causing peakflows in the Pacific Northwest, the interactive effects of a snowpack and watershed physiography on streamflow are largely undocumented. This study investigated the influence of soil and snowpack moisture on peakflow hydrograph shape in three small (< 60 ha) control sub-watersheds...

Road networks, timber harvest, and the spread of Phytophthora root rot infestations of Port-Orford-cedar in southwest Oregon

Creator:: Clark, William C.
Abstract:: Phytophthora lateralis is the causal agent of cedar root rot, a fatal forest pathogen whose principal host is Chamaecyparis lawsoniana (Port-Orford-cedar), a predominantly riparian-restricted endemic tree species of ecological, economical, and cultural importance to coastal Oregon and California. Local scale distribution of P. lateralis is thought to be associated with...

A Novel Approach to Process-based River Restoration in Oregon : Practitioners’ Perspectives, and Effects on In-stream Wood

Creator:: Bianco, Stephanie R.
Abstract:: The widespread fragmentation, channelization, and simplification of river ecosystems has had acute environmental impacts, including degradation of water quality and habitat and biodiversity loss (Vörösmarty et al., 2010). These concerns have incited an increased focus on reestablishing ecological and hydrogeomorphological functions and improving habitat that has been lost in riverine...

Effects of harvest and roads on in-stream wood abundance in the Blue River Basin, western Cascades, Oregon

Creator:: Czarnomski, Nicole M.
Abstract:: Despite many studies of large wood in streams, few landscape scale studies have been conducted. Large-scale studies can reveal how the history of forest harvest and road building has influenced wood patterns in streams of the Pacific Northwest. This study examined the relationships between wood in streams, timber harvest, and...

Age structure, developmental pathways, and fire regime characterization of Douglas-fir/western hemlock forests in the central western Cascades of Oregon

Creator:: Tepley, Alan J.
Abstract:: Descriptions of the fire regime in the Douglas-fir/western hemlock region of the Pacific Northwest traditionally have emphasized infrequent, predominantly stand-replacement fires and an associated linear pathway of stand development, where all stands proceed along a common pathway until reset by the next fire. Although such a description may apply in...

Forest-meadow dynamics in the central western Oregon Cascades : topographic, biotic,and environmental change effects

Creator:: Rice, Janine M.
Abstract:: Montane meadows comprise a small area of the predominantly forested landscape of the Oregon Cascade Range. Tree encroachment in the last century in these areas has threatened a loss of biodiversity and habitat. Climate change in the coming century may accelerate tree encroachment into meadows, and exacerbate biodiversity loss. Multiple...
