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...

Climate Variability and Plant-Pollinator Networks in the Cascade Range, Oregon

Creator:: Vickers, Melinda
Abstract:: Worldwide, networks of plants and pollinators are faced with the threat of climate change. The extent of this threat and the degree of adaptability is not yet understood. In Oregon, climate change is predicted to bring hotter and drier summers which may have consequences for pollinators and the resources they...

Forest Fire Effects on Radiative and Turbulent Fluxes over Snow : Implications for Snow Hydrology

Creator:: Gleason, Kelly E.
Abstract:: As a result of a warming climate, subsequent declining snowpack, and a century of fire suppression, forest fires are increasing across the western United States. However, we still do not fully understand how forest fire effects snowpack energy balance, nor the volume and availability of snow melt and associated water...

Spatial and temporal patterns of fire in the forests of the central Oregon Coast Range

Creator:: Impara, Peter C.
Abstract:: Fire history and fire regime were interpreted from tree ring analysis of 4320 stumps at 178 sites in a 25 by 55 km area in the central Oregon Coast Range. A total of 27 fire episodes were identified in a 516 year period, with sizes estimated at 18 to 544...

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...

Remote sensing methodology for bioenvironmental surveillance in the vicinity of the Boardman Coal-Fired Power Plant, Oregon

Creator:: Denkers, D. Scott
Abstract:: In 1979, the Geographic Applications Laboratory of the Department of Geography, Oregon State University, was retained by the Portland General Electric Company to form and supervise a program to monitor the bioenvironment in the vicinity of the Boardman Coal-Fired Power plant. This partially fulfills requirements of the Department of Energy...

Meadow classification in the Willamette National Forest and conifer encroachment patterns in the Chucksney-Grasshopper meadow complex, Western Cascade Range, Oregon

Creator:: Dailey, Michele Meadows
Abstract:: This study delineates and characterizes the distribution of montane meadows in the Willamette National Forest, identifies encroachment patterns in relation to topographic features and proximity to trees in the Chucksney-Grasshopper meadow complex, and examines tree species and age distributions in relation to distance from forest edges or isolated tree clusters...

Environmentally imposed problems of the range beef cattle industry in eastern Oregon

Creator:: Thomason, Leonora Marie
Abstract:: Beef cattle ranches provide a substantial portion of income in Oregon. Range beef cattle ranches are located on land having relatively low productivity and value. The ranches of interest for this study were among the largest and most extensive in the state. The purpose of the study was to examine...

A channel stability inventory for two streams on the eastern slopes of the Coast Range, Oregon

Creator:: Sachet, James A.
Abstract:: Stream channel stability for two tributaries of Rock Creek in the Oregon Coast Range is evaluated by application of a Stream Reach Inventory. Stability nomographs are constructed for graphical analysis of erosion potential. Results indicate that channel stability can be classified. One stream is rated as 'Poor' in resistance to...
