No Genetic Reserve in Fall-Run Salmon Populations

Human actions impact wild salmon's ability to evolve,
University of California - Davis, December 4, 2018.


Near Extinction
“...spring-run chinook are on the brink of extinction in most locations where they haven't already been lost.”

Sensitive to Everything Human
"...because they rely on clean, cold water throughout hot summer months, spring-run chinook are more vulnerable than fall-run chinook" to activities such as logging, mining, dams and water diversion, and to climate change.”

“Once spring-run chinook salmon disappear, they are not likely to re-emerge, indicates genetic analysis of the revered wild fish in a study led by the University of California, Davis.”

"If you lose the spring-run gene, you could potentially lose spring-run chinook forever.”


Bottom Line

Spring Run Chinook are on the way out, if our trend lines of growth, development, and continued expansion of the warming trends our growth and development triggers.
