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...

The capability of a GIS to contribute to the social assessment of forest communities : a case study of the Central Cascades Adaptive Management Area

Creator:: Burke, Tenley Boehm
Abstract:: Geographic Information Systems (GIS) have become an essential tool for evaluation and monitoring the biophysical data of natural landscapes. This study addresses the potential for using GIS in the social assessment of human landscapes that are associated with geographic regions of interest. Using the communities surrounding Oregon's federally designated Central...

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...

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...

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...

A review of the social component of ecosystem assessments with recommendations for Oregon

Creator:: Armstrong, Catriona M. M.
Abstract:: Large-scale ecosystem assessments aim to assist ecosystem management by synthesizing current scientific knowledge on an area, and by providing a foundation for policy discussions and decisions on land management. These assessments go beyond traditional research efforts by moving away from narrow scope, system, and institutional boundaries, and by attempting to...

Private forests-public resources : policy and landscape on the Oregon Coast Range

Creator:: Langridge, Ruth
Abstract:: The forests of the Oregon Coast Range have been both the principal natural resource, and for many years, the primary economic base of the region. In the past thirty years, changing social and economic factors have created new visions for these forests, leading to conflict over the appropriate management of...

Examining bias in estimating the response variable and assessing the effect of using alternative plot designs to measure predictor variables in diameter growth modeling

Creator:: Zumrawi, Abdel Azim M. A.
Abstract:: Diameter growth of Douglas-fir (Pseudotsuqa menziesii (Mirb.) Franco) estimated from increment cores was compared with that obtained from repeated measurements of tree diameter on permanent plots located in two Douglas-fir study areas in the central Coast Range of Oregon. Growth was measured for a 6-year period (1979- 1985). Diameter growth...

Taper, crown, and volume responses of a coastal Oregon Douglas-fir stand to sulfur treatments for control of Swiss needle cast

Creator:: Younger, Nicole L.
Abstract:: For nearly two decades, foresters in the Oregon Coast Range have been witnessing a substantial decease in Douglas-fir (Pseudotsuga menziesii var. menziesii [Mirb.] Franco.) vigor and growth, caused by Swiss needle cast (Phaeocryptopus gaeumannii). Currently, no solutions are in sight but aerially-applied sulfur may alleviate Swiss needle cast and its...
