Managing western hemlock forests in the Oregon Coast Range

Creator:: Duddles, Ralph E., Fitzgerald, Stephen Arthur, and Oregon State University. Extension Service
Abstract:: Western hemlock forests in the coastal areas of Oregon are some of the most productive and diverse forests in the world. This rich diversity represents both a challenge and an opportunity for woodland owners interested in managing western hemlock on their property.

Structural development of late successional forests in the central Oregon Coast Range : abundance, dispersal, and growth of western hemlock (Tsuga heterophylla) regeneration

Creator:: Schrader, Barbara A.
Abstract:: Patterns of western hemlock regeneration were studied in relation to forest structural development and environment in the Oregon Coast Range. Density of western hemlock seedlings was examined across the climatic gradient from cool, moist coastal areas to the seasonally hot and dry Willamette Valley Margin. Seedling densities were most strongly...

Animal damage, vegetative competition and growth of western hemlock seedlings in the Coast Range of Oregon

Creator:: Hyatt, Joan Marie
Abstract:: The growth of western hemlock during the first four years of seedling establishment was examined in a competitive environment in which seedlings were exposed to various types of animal damage and salmonberry and/or alder competition. The study utilized an existing Nelder/replacement series experiment which focused on the competitive effects among...

Effects of residual trees on growth of young to mature Douglas-fir and western hemlock in the western central Oregon Cascades

Creator:: Zenner, Eric K.
Abstract:: The purpose of this study was to assess how growth of young to mature Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) and western hemlock (Tsuga heterophylla (Raf.) Sar.) in mixed stands was influenced by the presence of residual trees. Fourteen paired plots with and without residual trees were examined in a retrospective...

Riparian litter inputs to streams in the central Oregon Coast Range

Creator:: Hart, Stephanie K.
Abstract:: Riparian zone vegetation can influence terrestrial and aquatic food webs through variations in the amounts, timing, and nutritional content of leaf and other litter inputs. Differences in vegetation composition and density, as well as riparian topography, may modulate the strength and quality of these inputs. Changes in inputs to small...

Contributions of riparian vegetation and stream morphology to headwater stream temperature patterns in the Oregon Coast Range

Creator:: Smith, Danielle D.
Abstract:: The role of riparian forests in maintaining temperatures of headwater streams is well established and is a foundation of forest practice rules designed to protect streamwater quality. However, detailed investigation is still needed quantifying specific characteristics of stream systems that affect streamwater temperature including riparian features, stream morphology, and subsurface...

A study of in stream complexity in three Oregon Coast Range watersheds

Creator:: Anderson, Paul Khalil
Abstract:: This study investigates patterns of physical structure organization in stream networks. In particular, it seeks to describe patterns of wood, boulders, pools and slope that are evident in stream channels and to determine whether patterns of these elements are influenced by network-level controls. The four in-stream parameters were combined to...

The use of ơ15N and ơ¹³C to analyze food webs and identify source-sink relationships in riparian canopy vegetation of the Oregon Coast Range

Creator:: Scott, Emily E.
Abstract:: In the Coast Range of western Oregon, some natural resource managers are converting red alder-dominated riparian areas to conifers to increase the future source of in-stream large wood for salmonid habitat. However, studies in Alaska have shown red alder-dominated riparian areas support greater invertebrate biomass compared to conifer-dominated areas. In...

A characterization of road hydrology in the Oregon Coast Range

Creator:: Gilbert, Erin H.
Abstract:: Forest roads alter hillslope hydrologic processes by intercepting, concentrating, and rerouting storm runoff. Current road drainage guidelines are based on minimizing erosion and do not take into account the impact of forest roads on hillslope hydrology. This work monitors ditch flow and rainfall for 10 road segments over the course...

Hydrology of five forest roads in the Oregon Coast Range

Creator:: Marbet, Christine Erica
Abstract:: Understanding the impact of low volume road networks on forested watersheds is important for future forest management and watershed restoration. This study characterized the hydrology of five segments of forest road in the Oregon Coast Range. Rainfall, infiltration, road surface runoff, and intercepted subsurface flow were measured at each road...
