A replicated before–after-control-impact study was used to test effectiveness of Oregon’s (USA) riparian
protection measures at minimizing increases in summer stream temperature associated with timber harvest.
Sites were located on private and state forest land. Practices on private forests require riparian management
areas around fish-bearing streams; state forest’s prescriptions are...

Many wind-power facilities in the United States have established effective monitoring programs to determine turbine-caused fatality rates of birds and bats, but estimating the number of fatalities of rare species poses special difficulties. The loss of even small numbers of individuals may adversely affect fragile populations, but typically, few (if...
Understory vegetation communities are critical components of forest ecosystems. As a result, the importance of modeling understory vegetation characteristics in forested landscapes has become more apparent. Abundance measures such as shrub cover are bounded between 0 and 1, exhibit heteroscedastic error variance, and are often subject to spatial dependence. These...
Oregon’s forested coastal watersheds support important cold-water fisheries of salmon
and steelhead (Oncorhynchus spp.) as well as forestry-dependent local economies. Riparian
timber harvest restrictions in Oregon and elsewhere are designed to protect stream habitat
characteristics while enabling upland timber harvest. We present an assessment of riparian
leave tree rule effectiveness...

We are studying the impacts of parasites on threatened stocks of Oregon coastal coho
salmon (Oncorhynchus kisutch). In our previous studies, we have found high infections of
digeneans and myxozoans in coho salmon parr from the lower main stem of West Fork Smith
River (WFSR), Oregon. In contrast parr from...
