The land-water interface : patterns of riparian vegetation and channel morphology in the Oregon Coast Range system

Creator:: Takahashi, Mayumi
Abstract:: This study was conducted to describe variation of riparian vegetation in an Oregon Coast Range system according to geomorphic characteristics and in relation to streamflow. Specific objectives of this study were to: I) examine if the vegetation composition and structure of the riparian forest varied among channel-reach morphologies, 2) examine...

Empirical modeling of windthrow occurrence in streamside buffer strips

Creator:: Drake, Timothy P.
Abstract:: Streamside buffer strips provide numerous benefits to stream ecosystems. The buffer strips create shade, provide shelter for wildlife, act as barriers to logging debris during and after timber harvest, and serve as a continued source of large woody debris. Quantifying woody inputs resulting from windthrow provides managers with estimates for...

Characterizing early-seral competitive mechanisms influencing Douglas-fir seedling growth, vegetation community development, and physiology of selected weedy plant species

Creator:: Dinger, Eric J.
Abstract:: Three studies were conducted to characterize and present early-seral competition between Douglas-fir seedlings and the surrounding vegetation communities during Pacific Northwest forest establishment. The first experiment served as the foundation for this dissertation and was designed to quantify tradeoffs associated with delaying forest establishment activities by introducing a fallow year...
Resource Type:: Dissertation
Full Text:: first year. These treatments were applied in two replicated experiments within the Oregon Coast Range

Tradeoffs associated with managing forested landscapes for multiple-uses

Creator:: Lichtenstein, Mark E.
Abstract:: This study focuses on the tradeoffs that exist for managing forested landscapes for biodiversity and timber production. Tradeoff evaluation is important to natural resource managers so they can understand the benefits and costs of alternative management prescriptions. The study examines three watersheds in the Oregon Coast Range and 166 terrestrial...

Combining the Recreation Opportunity Spectrum (ROS) and Geographic Information Systems (GIS) to assess current and future recreation conditions in Oregon's coast range

Creator:: Rogan, Lael M. (Lael Michaela), 1970-
Abstract:: Conflict over the best way to manage Oregon's public lands makes a land planner's job extremely challenging. Multiple uses, federal mandates, and constantly evolving knowledge all contribute to the difficulty of determining how to best use the land. The Coastal Landscape Analysis and Modeling Study (CLAMS) was developed in 1994...

Alterations in Douglas-fir crown structure, morphology, and dynamics imposed by the Swiss needle cast disease in the Oregon Coast Range

Creator:: Weiskittel, Aaron R.
Abstract:: Plants respond to defoliation in many different and complex ways, depending on their growth habit and form as well as the extent and duration of the defoliation. Tree crowns have been shown to be quite sensitive to disturbances such as defoliation, however quantitative relationships have rarely been developed, making the...

Distribution and growth of advance Douglas-fir regeneration in commercially thinned stands in the Oregon Coast Range

Creator:: Beer, Louis W.
Abstract:: This study examined the abundance, size, growth, and age of advance regeneration Douglas-fir, beneath an eighty year-old overstory at a single site on plots subjected to different overstory thinning treatments. Treatments consisted of keeping overstory basal area within upper and lower limits for periods of 12-17 years which, depending upon...

Temporal and spatial variability of historic fire frequency in the southern Willamette Valley foothills of Oregon

Creator:: Robbins, Danielle
Abstract:: A crossdated fire history was reconstructed for a 1562 km2 area in the southern Willamette foothills of Oregon, using fire scars and tree origin years from twelve sites. The purpose of this study was to determine fire frequency for each site and to quantify temporal and spatial variability of fire...

Kinship, environment and the Forest Service : homesteading in Oregon's Coast Range

Creator:: Prior, Jan M.
Abstract:: The settlement history of a remote area in the Coast Range of Oregon, from the 1870s to the 1930s, is examined through factors that may have influenced the success or failure, and length of residence of the homesteaders and later residents. Despite the rugged and isolated location, a small community...

Land ownership and forest cover in the Oregon Coast Range : spatial pattern and social ground-truthing

Creator:: Stanfield, Brooks J.
Abstract:: We use qualitative and quantitative methods to explore social and spatial relationships between land ownership and forest cover in the Oregon Coast Range. Using a Geographic Information System (GIS) and regression analysis, we tested for spatial relationships between the structure of land ownership and forest cover across 66 watersheds in...
