Making room for salmon

How can Puget Sound generate more salmon? That question has been at the center of ecosystem recovery efforts for decades. But even as scientists and conservationists make progress on many fronts — from breaching dams to cleaning up the water — they have faced one especially complicated and frustrating limitation: Salmon need more estuaries. We look at how local tribes are working to restore this critical habitat.

Invasive species in Puget Sound

A main story and 3 vignettes on the sources, impacts, and regulation of non-native species entering local waters. Sponsored by U.S. EPA and Washington Department of Fish and Wildlife.

Nearly half of the invasive species in Puget Sound's marine waters have been found within the last 20 years. Among the most common pathways for invaders are ships and boats that may carry thousands of tiny hitchhikers. Our series looks at this growing threat and some of the species of top concern.  To be notified of new Salish Sea Currents stories, subscribe to the Puget Sound Institute eNews.

About the booklet

Rethinking shoreline armoring

An in-depth series on issues related to shoreline armoring in the Puget Sound region. Sponsored by U.S. EPA and Washington Department of Fish and Wildlife.

Salish Sea Currents presents an in-depth series focusing on shoreline armoring in the Puget Sound region. Close to a third of Puget Sound's shoreline is classified as armored with bulkheads and other structures meant to hold back storm surge and erosion. But new studies reveal the often significant toll this is taking on the environment. To be notified of new Salish Sea Currents stories, subscribe to the Puget Sound Institute eNews.
