    Are we making progress on salmon recovery?

    In recent decades, hundreds of millions of dollars have been spent to restore habitat for Puget Sound salmon. In this article, we look at how scientists are gauging their progress. Are environmental conditions improving or getting worse? The answer may depend on where you look and who you ask.

    Contaminants higher in resident 'blackmouth' Chinook

    Many of Puget Sound's Chinook salmon spend their entire lives in local waters and don't migrate to the open ocean. These fish tend to collect more contaminants in their bodies because of the sound's relatively high levels of pollution.

    New theory rethinks spread of PCBs and other toxics in Puget Sound

    Researchers are proposing a shift in thinking about how some of the region’s most damaging pollutants enter Puget Sound species like herring, salmon and orcas.

    Global Range
    Includes all naturally spawned populations residing below impassable barriers (e.g., long-standing, natural waterfalls) in the Puget Sound region from the North Fork Noonsack River to the Elwha River on the Olympic Peninsula, inclusive (NMFS 1999). Included are naturally spawning populations founded by hatchery populations that originated from within this ESU (but does not include salmon from the spring-run program at the Quilcene National Fish Hatchery and their progeny) (NMFS 1999).<br><br>The majority of of natural production is concentrated in just two basins (Good et al. 2005).
