Use of sheep to control weeds in a ryegrass-white clover pasture in which Knob Cone-Monterrey hybrid pine trees had been planted was investigated in Corvallis, Oregon during 1997-1998. Treatments consisted of an ungrazed control (C) and grazing applications to achieve 25 (L), 50 (M) or 75 (H) percent utilization of...
In what is called participatory democracy scholars and practitioners have been calling for the involvement of citizens in decisions that affect their lives. Citizens who emerge to participate in technically complex, decision-making processes find that their involvement is often minimized, disregarded, or neglected due to barriers such as specialized scientific...
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...

Forest understory vegetation is influenced by broad-scale variation in climate, intermediate-scale variation in topography, disturbance and neighborhood interactions. However, little is known about how these multi-scale controls interact to influence observed spatial patterns. We examined relationships between the aggregated cover of understory plant species (%C[subscript U]) and multi-scale controls using...
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...

Monitoring unstable slopes with terrestrial laser scanning (TLS) has been proven effective. However, end users still struggle immensely with the efficient processing, analysis, and interpretation of the massive and complex TLS datasets. Two recent advances described in this paper now improve the ability to work with TLS data acquired on...
