Salmon, Steelhead Still Face Threats in Interior Columbia Basin
NOAA Fisheries researchers have determined that salmon and steelhead species in the Interior Columbia Basin protected under the Endangered Species Act (ESA) still need such protection, due to the impact of climate change and the need for further recovery actions.
The five-year review, released in mid-August, focuses on species in the Snake River and upper and middle Columbia River systems. It recommends further improving the passage of these fish through hydropower dams, restoring tributary and estuary habitat, controlling predators and modifying hatchery practices to improve the resilience of these species.
The review of Snake River spring/summer-run Chinook salmon noted an increased level of concern for the species, based on declining population trend and the impacts of climate...
