Management of habitat for bats requires sound information on their habitat requirements. I used radio telemetry to identify 80 roosts for 24 long-eared myotis (Myotis evotis); 74 roosts were identified for 21 females and 6 roosts for 3 males.
Females primarily used dead and defective conifer trees (n=22) and conifer...
The purpose of this study is to examine the relationship between land management practices of Indian communities prior to contact with Europeans and the nature or character of subsequent catastrophic forest fires in the Oregon Coast Range. The research focus is spatial and temporal patterns of Indian burning across the...

The influence of anthropogenic aerosols, in the form of ship exhaust effluent, on the microphysics and radiative properties of marine stratocumulus is studied using data gathered from the U.K. Met. Office C-130 and the University of Washington C-131A aircraft during the Monterey Area Ship Track (MAST) experiment in 1994. During...
A first-order approximation is made of the frequency and magnitude of bedload transport downstream of the Pelton-Round Butte Dam Complex, lower Deschutes River, Oregon with implications for salmonid spawning habitat. Field measurements of channel hydraulics, geometry, and particle size were combined with one-dimensional hydraulic and bedload transport models to determine...
Focus on Forestry is published three times each year (Fall, Winter, Spring) by the College of Forestry, Oregon State University. Our goal is to keep Forestry alumni and friends informed about the College of Forestry and its many activities and programs. We welcome letters, phone calls, and e-mail comments from...

The Greenstone Mountain area, which includes the Utopia mining
district, is located in the foothills of the Pioneer Range, Beaverhead
County, Montana. Approximately 12, 600 feet of Paleozoic and
Mesozoic sedimentary rocks and an undetermined thickness of Precambrian
sediments and Late Cretaceous igneous rocks are exposed
within the area of...

The literature related to valuing the protection of threatened and endangered marine species using stated preference non-market valuation methods is summarized and examined. This includes an evaluation of the suitability of existing threatened, endangered, and rare marine species values as inputs for the analysis of marine and coastal policies, and...
A concert of original music and script written, composed, and conducted by members of the teaching staff of Oregon State University in honor of the 100th anniversary of the state of Oregon.
Riparian areas in the arid western United States are critical ecosystems that have been severely degraded by a variety of land and water uses over the last 100 years. In this study, the composition and structure of floodplain vegetation along the Lower Owens River in eastern California was quantitatively described...
Washington State fisheries and Washington State Treaty Tribes are becoming increasingly restricted in harvest of wild salmon due to US Endangered Species Act listings of salmon species, marine mammal predation by both ESA listed Southern Resident Killer Whale (SRKW) and US Marine Mammal Protection Act protected pinnipeds, salmon habitat destruction,...
Although most eastern North Pacific (ENP) gray whales feed in the Bering, Beaufort,
and Chukchi Seas during summer and fall, a small number of individuals,
referred to as the Pacific Coast Feeding Group (PCFG), show intra- and interseasonal
fidelity to feeding areas from northern California through southeastern Alaska. We
used...
These six stories represent a child's search for identity. The first story, "Road Map," is intended to be independent from the other pieces in this collection, but has been included because it is clearly set in the same place and explores many of the same themes of the other pieces....

As the global demand for natural resources increases, more land will be intensively managed for the production of commodities such as timber, with potential consequences to biodiversity, ecological functioning and ecosystem services provided to society. Although there is strong consensus that intensive land management practices can negatively affect biodiversity, less...
Wire and fiber ropes used in rigorous CBOS (cyclic bend over sheave)
applications were investigated. Small diameter stainless steel, tungsten, and Vectran®
ropes were tested over small sheaves at high loads and cycle speeds. Sheaves were made
with Al6061-T6511 and Al7075-T651 and were coated with 0.002” hard coat anodize;
some...
The Rock Creek area consists of 53 square miles located in
the eastern foothills of the Pioneer Mountains, Beaverhead County,
Montana. Approximately 8, 500 feet of late Paleozoic and early
Mesozoic contact-metamorphosed sedimentary rocks and late Mesozoic
sedimentary rocks are exposed in the area of study.
Most of the late...

their first coach Eddie O'Connell, won their first intercollegiate meet,...
The purpose of this document is to summarize the best scientific information presently available for bull trout (Salvelimus confluentus) throughout Oregon and to review their historical and current status. What started out as a relatively simple exercise to review and update the status report by Ratliff and Howell (1992) based...
