Unusually warm river conditions killed most adult sockeye salmon migrating up the Columbia and Snake River system in 2015, reflecting a “new normal” with climate change, a new NOAA Fisheries study finds.
In a letter Friday (Oct.9) the four Northwest states announced they have agreed to work together to rebuild Columbia River salmon and steelhead stocks and to advance the goals of the Columbia Basin Partnership Task Force.
To date in 2020, 1,217 wildfires have burned 1,473,522 million acres of National Forest System lands in California; 8,486 wildfires have burned over 4 million acres across all jurisdictions in California.
Oregon again was recognized as a leader in efforts to stem climate change and ocean acidification and hypoxia (OAH).
Spawn timing for wild chinook salmon in the Skagit River system in Washington is slowly occurring later in the year as the river warms due to climate change, a finding that fits with previous research. However, the trend for hatchery-origin stray chinook salmon in the same river is towards earlier spawning, according to a recent study.
Squeezed by changing ocean conditions that limit their food options and the long-term loss of old forest needed for nesting, marbled murrelets would benefit most from conservation efforts that take both ocean and forest into account, new research by Oregon State University shows.
As oceans warm due to climate change, scientists are trying to predict how marine animals -- from backboned fish to spineless jellyfish -- will react.
Natural disasters alone are not enough to motivate local communities to engage in climate change mitigation or adaptation, a new study from Oregon State University found.
The size of salmon returning to rivers in Alaska has declined dramatically over the past 60 years because they are spending fewer years at sea, according to a new study led by researchers at the University of California, Santa Cruz, and the University of Alaska Fairbanks.
