Forestry herbicide use on private forest lands in Lincoln and Benton County Oregon, 1991-1994

Creator:: Godino, John Alessandro
Abstract:: The use of phenoxy herbicides is an established practice in industrial forestry, particularly in the Pacific Northwest. Forestry herbicide use in this region has often been controversial. To better understand the spatial patterns of herbicide use and the potential for human health and environmental impacts, a landscape level perspective is...

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...

The effects of ownership pattern on forest road networks in western Oregon

Creator:: Freid, Matthew A.
Abstract:: The pattern of ownership imposed on the-forest landscape of Western Oregon defines the boundaries in which differences in jurisdiction, regulation, and land use operate. Road building is controlled by these factors, and in turn has an effect on the cumulative effects of human utilization of the forest. This study examined...

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...

The historic and contemporary ecology of western Cascade meadows : archeology, vegetation, and macromoth ecology

Creator:: Highland, Steven A.
Abstract:: Montane meadows in the western Cascades of Oregon occupy approximately 5% of the landscape, but contribute greatly to the region's biodiversity. Western Cascades meadows are dynamic parts of the landscape and have contracted by over 50% in the past two hundred years in the HJ Andrews Experimental Forest (hereafter Andrews...

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...

Precipitation-snowmelt timing and snowmelt augmentation of large peak flow events, western Cascades, Oregon

Creator:: Jennings, Keith S.
Abstract:: Despite advances in the understanding of rain-on-snow storms and their resulting peak flows, little is understood about the response of snowmelt to precipitation and the relative timing of the two at multiple temporal scales within such events. To address this issue, climate, snowmelt, and streamflow data were analyzed for 26...

Diversity, Generalization, and Specialization in Plant-Pollinator Networks of Montane Meadows, Western Cascades, Oregon

Creator:: Helderop, Edward
Abstract:: Despite the importance of plant-pollinator interactions for ecological communities, few long-term observational studies have been conducted of plant-pollinator networks. Using four years of plant-pollinator interaction data from 18 meadows in the Willamette National Forest, Oregon, this thesis examined how meadow size, the amount of nearby meadow habitat, weather, degree days,...

Do vigorous young forests reduce streamflow? Results from up to 54 years of streamflow records in eight paired-watershed experiments in the H. J. Andrews and South Umpqua Experimental Forests

Creator:: Perry, Timothy D.
Abstract:: This study quantified the magnitude and timing of summer streamflow deficits in paired-watershed experiments in the Cascade Range of Oregon where mature and old-growth conifer forests were subjected to clearcutting, patch cutting, and overstory thinning treatments in the 1960s and 1970s. Hydrologic effects of clearcutting, small-patch cutting, and overstory thinning...

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...
