Early high Cascade silicic volcanism : analysis of the McKenzie Canyon and Lower Bridge tuff

Creator:: Eungard, Daniel W.
Abstract:: Silicic volcanism in the central Oregon Cascade range has decreased in both the size and frequency of eruptions from its initiation at ~40 Ma to present. The reasons for this reduction in silicic volcanism are poorly constrained. Studies of the petrogenesis of these magmas have the potential for addressing this...

Genesis of some soils in the central western Cascades of Oregon

Creator:: Brown, R. B.
Abstract:: Soils representative of several landscape units in the H. J. Andrews Experimental Forest, Western Cascade Range, were sampled, analyzed, and tentatively classified. Genetic inferences were drawn relating soils to landscape position and other factors of soil formation. Descriptive information and nutrient capital data were provided to support ecosystem modelling efforts...

Selection of day roosts by female long-legged myotis (Myotis volans) in forests of the central Oregon Cascades

Creator:: Ormsbee, Patricia
Abstract:: Measuring habitat selection by bats is complicated by their intricate life cycle. Scaling habitat measurements to reflect a hierarchal habitat selection process can help to define habitat associations of bats. I assessed day roost habitat of female long-legged myotis at four scales: the roost structure, micro-habitat surrounding the roost, the...

Movements and habitat asociations of northern flying squirrels in the Central Oregon Cascades

Creator:: Martin, Karl J.
Abstract:: We used radio-telemetry techniques to estimate home range size, movements, den sites, and habitat selection of 39 northern flying squirrels (Glaucomys sabrinus) in 2 old- and 2 second-growth stands in the central Oregon Cascades. Sampling periods were at night during summer and fall of 1991-92. Home ranges were smaller for...

Gravity anomalies and their structural implications for the southern Oregon Cascade Mountains and adjoining Basin and Range province

Creator:: Veen, Cynthia A.
Abstract:: Gravity measurements made during 1979 and 1980, combined with existing gravity measurements, provide data for the interpretation of upper crustal structures relevant to the assessment of the geothermal potential of south-central Oregon. West of Upper Klamath Lake, free-air gravity anomalies trend north-south and average near 35 mgals. East of Upper...

Habitat associations of woodpeckers at multiple scales in managed forests of the Southern Oregon Cascades

Creator:: Brett, Tiffany A.
Abstract:: I studied nest-site characteristics and habitat relationships for three species ofprimary cavity-nesting birds--hairy woodpecker (Picoides villosus), northern flicker (Colaptes auratus), and red-breasted sapsucker (Sphyrapicus ruber)-- over spatially heterogeneous landscapes in managed forests of the Southern Oregon Cascades during 1995 and 1996. The study was conducted on the Diamond Lake Ranger...

Hydrologic integration of forest roads with stream networks in two basins, western Cascades, Oregon

Creator:: Wemple, Beverly C.
Abstract:: This study assessed how logging-access roads may have contributed to observed historical increases in peak discharges associated with small and large logged basins in the western Cascades of Oregon. The study was conducted on the Lookout Creek (62km²) and the upper Blue River (118km²) basins. Potential road effects on hydrology...
