The Cougar, The Tick, and Human Wellbeing: The Social, Economic, and Ecological Valuations of Living with Cougars in Oregon.

Creator:: Miller, Allyson
Abstract:: The overarching objective of this paper is to identify how the three tiers of human well-being (i.e., economics, ecosystems, and social) are linked to healthy landscapes and a species-rich ecosystem mediated by healthy cougar populations. Does the cougar help mitigate Oregon’s Lyme disease, chronic wasting disease (CWD), or elements of...

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...

Evaporative heat loss of the upper Middle Fork of the John Day River, northeastern Oregon

Creator:: Benner, David A.
Abstract:: Evaporation was studied along the Middle Fork of the John Day River in northeastern Oregon. Evaporation pans and various meteorological sensors recorded data at nine sites during the summer of 1998; measurements were made at each site over a 3-4 day period. A Dalton-type evaporation model was produced using water...

Reach scale sampling metrics and longitudinal pattern adjustments of small streams

Creator:: Robison, E. George
Abstract:: Several types of channel morphology measurement parameters used to characterize fish habitat of small streams are refined, developed and evaluated in terms of their accuracy, precision, and sensitivity to disturbance. Data for 74 stream reaches in Oregon and Alaska are used in analysis. Over half the reaches are from a...

Shallow aquifer characteristics adjacent to the upper Middle Fork John Day River, eastern Oregon

Creator:: Hopson, Richard G.
Abstract:: Subsurface inputs into lotic systems are a primary mechanism for cooling streams with high ambient water temperatures. Objectives of this study include: 1) to determine the effectiveness of Forward Looking Infrared (FLIR) thermal imagery to detect shallow aquifers, 2) to characterize certain physical, spatial, and temporal characteristics of the fluvial,...

The effect of the size and orientation of large wood on pool volume in two Oregon Coast Range streams

Creator:: Lombard, Pamela
Abstract:: This study was conducted to determine how the size and orientation of large wood placed in streams in combination with peak flows, substrate and channel gradient affect pool volume, surface area and maximum depth in two coastal Oregon streams. Eighteen Douglas-fir (Pseudotsuga menziesii) logs were placed in each of two...

Summertime stream temperatures in the North and South Forks of the Sprague River, south central Oregon

Creator:: Friedrichsen, Paul T.
Abstract:: The Upper Sprague River Watershed (North and South Forks of the Sprague River) in south central Oregon provides important habitat for salmonid species, including native bull trout (Salvelinus confluentus) and redband trout (Oncorhynchus mykiss ssp.). Concern over the loss of viable habitat for these species has increased due to reductions...

Object Watershed Link Simulation (OWLS)

Creator:: Chen, Huaisheng
Abstract:: Object Watershed Link Simulation (OWLS) is a physically based watershed model. In the OWLS model, a watershed is defined as a three-dimensional object with linkages between cells and their attributes (e.g., area, slope, soil type, etc.). A cell is defined as the linkages of edges and their attributes (e.g., length,...

Stream temperatures, riparian vegetation, and channel morphology in the Upper Grande Ronde River Watershed, Oregon

Creator:: Bohle, Todd S.
Abstract:: The Upper Grande Ronde River Watershed in northeastern Oregon is considered important habitat for threatened stocks of chinook salmon (Oncorhynchus tshawytscha). Documented reductions in channel complexity and riparian vegetation within the watershed have increased concern over loss of viable habitat. An important component of salmonid habitat is stream temperature during...

Sedimentation of beaver ponds in an Oregon Coast Range stream

Creator:: Ringer, Gina O.
Abstract:: Through the trapping of sediment behind dams, the presence of beaver in a watershed may cause substantial changes to fluvial and geomorphic processes. In an effort to investigate sedimentation patterns in beaver ponds in the Oregon Coast Range, a case study was made of the annual accumulation of sediment in...
