All Regions
Declines in Pacific salmon abundance are widespread, with abundance below the long-term average for most regional salmon populations. A few hopeful exceptions highlight the resilience of salmon and opportunities for recovery.

Key Findings
1.Although some regional salmon populations show signs of recovery, two-thirds remain below their long-term average.
2.Increasing numbers of sockeye and Chinook are bringing renewed hope for some salmon-dependent communities and ecosystems.
3.Pink salmon are proving their resilience, returning in large numbers across many regions.
4.While most salmon species seem to be struggling in northern and central regions, data gaps make it hard to know just how serious and widespread the declines are.

FACTORS AFFECTING THE STATE OF SALMON
The salmon life cycle extends from freshwater streams and lakes to the North Pacific Ocean, exposing salmon to numerous pressures that can accumulate and interact to influence survival. Over the past 150 years, the number of factors affecting the abundance of Pacific salmon have dramatically increased, challenging salmon survival.
