OSU: Northwest marine ecosystem ‘dead zones’ unprecedented, may be linked to climate change
During the summer of 2006, anoxia, a complete lack of oxygen in the water, was recorded off the central Oregon coast for the first time.
OSU: Managed Northwest conifer forests threaten many species
When the primary goal of a forest is sustainable timber production, the lack of historic tree diversity, shrub and vegetation species may have long-term impacts on forest health.
TWS: Northern spotted owl recovery plan flawed

Washington state’s Puget Sound shoreline targeted for restoration, protection
Washington state’s Puget Sound is the focus of a large-scale estuarine restoration project, spearheaded by conversation organizations hoping to amass a multi-billion dollar warchest.
River sediment buildup may be a factor in certain subduction zone earthquakes
Over millions of years, sediment typically accumulates to great depths, from one-half mile to nearly 2 miles, and in rare cases, 3 miles deep.
UW biologist: Spawning salmon behavior triggers stream ecosystem changes
The “rototilling” effect most happens wherever salmon are found in high densities, such as British Columbia, Alaska and some individual streams in the Pacific Northwest.
