Behavioral responses of Rocky Mountain Elk (Cervus elaphus) to recreational disturbance

Creator:: Naylor, Leslie M.
Abstract:: I measured responses of free-ranging Rocky Mountain elk (Cervus elaphus) to recreational disturbance at Starkey Experimental Forest and Range, Oregon from April to October, 2003 and 2004. Resting, feeding, and travel activities of 13 cow elk were recorded at 5-minute intervals using Actiwatch™ motion sensors. Elk were subjected to four...

Contemporary forest road management with economic and environmental objectives

Creator:: Thompson, Matthew P.
Abstract:: One of the basic questions facing transportation planners and road managers is how to provide and maintain a road system that provides efficient access to the forest while limiting adverse effects roads can have on water and soil resources. The purpose of this study is to develop decision support models...

Effects of forest roads on surface and subsurface flow in southeast Alaska

Creator:: McGee, Katherine E.
Abstract:: Well water levels and ditch flow were used to evaluate road-induced changes in surface and subsurface flow for two sites (Trocadero and Polk) in southeast Alaska. At the Trocadero Site, low water levels before and peak water levels during a storm were used to test for differences in subsurface water...

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...

Effects of thinning on forest-floor vertebrates and analysis of habitat associations along ecological gradients in Oregon coastal Douglas-fir forests

Creator:: Suzuki, Nobuya
Abstract:: Thinning has the potential to increase structural diversity of managed forests for wildlife. During 1994-1996, I conducted experimental and observational studies using pitfall trapping to assess short-term and potential long-term effects of thinning on abundance and reproduction of forest-floor vertebrates in Douglas-fir (Pseudotsuga menzeisii) forests of the Oregon Coast Range....

Examining effectiveness of Oregon’s forest practice rules for maintaining warm-season maximum stream temperature patterns in the Oregon Coast Range

Creator:: Fleuret, Jennifer Marie
Abstract:: Stream temperature, as an important component of stream ecosystems, can be affected by forest harvesting through removal of riparian shade and changes in hydrology. Riparian Management Areas (RMAs), as implemented through the current Oregon Forest Practice Rules, are designed, in part, to maintain stream temperature following forest harvesting. However, effectiveness...

Exotic plant species dynamics from 1994 to 2005 on road networks in forested landscapes of western Oregon

Creator:: Sheehy, Samantha
Abstract:: Although the Pacific Northwest has the least proportion of non-native plant species in relation to other regions of North America, exotic species continue to spread into mountainous areas, including the Cascade Range. In a forested landscape, road networks can act as corridors for exotic plant dispersal and establishment, helping species...

Four centuries of soil carbon and nitrogen change after severe fire in a Western Cascades forest landscape

Creator:: Giesen, Thomas William
Abstract:: Fire is a major disturbance process in many forests. Long-term studies of the biogeochemical effects of fires, especially on soils, are very rare. Consequently, long-term effects of fire on soils are often hypothesized from short-term effects. In a chronosequence study, I studied 24 western Cascades (Oregon) forest stands thought to...

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...

Influences of clearcut logging on macroinvertebrates in perennial and intermittent headwaters of the Central Oregon Coast Range

Creator:: Banks, Janel
Abstract:: This research was designed to broaden the understanding of how timber-harvest affects aquatic macroinvertebrates in perennial and intermittent headwater streams. This study compared emergent and benthic macroinvertebrate assemblages from 20 headwater streams in the central Oregon Coast Range that varied by harvest condition and flow duration. Through comparison of the...
