Christopher Dunagan concludes his excellent series on the return of the Elwha River.
Prehistoric-looking lamprey are recolonizing parts of the Elwha River that they have not occupied for more than 100 years. Like salmon, the culturally and ecologically important fish also move from saltwater into rivers to spawn. And like salmon, lamprey were devastated by the dams that once blocked their way. We conclude our series ‘Returning home: The Elwha’s genetic legacy.’

Excellent series by long time Northwest journalist Christopher Dunagan
Following dam removal, migratory salmon have been free to swim into the upper Elwha River for the first time in 100 years. Their actual behaviors and reproductive success may well be driven by changes in their genetic makeup. Our seven-part series ‘Returning home’ examines how the fish are doing and whether the Elwha’s genetic legacy remains intact.

Good overview of one of the most critical issues facing recovery of endangered salmon. Rising temperatures in streams.
In the Puget Sound region, elevated stream temperatures are believed to be one of the great downfalls for salmon, especially in areas where streamside vegetation has been removed by farming, forestry or development.
