Habitat is in Relatively Good Condition
Ecological concerns were developed by the National Oceanic and Atmospheric Administration’s National Marine Fisheries Service and are similar to “limiting factors” referred to in recovery plans. Each regional recovery plan has its own set of ecological concerns, which are changes to habitat that can lead to threats to salmon and steelhead survival. Tracking ecological concerns and habitat restoration facilitates more efficient and strategic planning. Tracking ecological concerns also allows for the assessment of habitat actions and their benefits to listed species and how these benefits may contribute to recovery.
This region has focused its habitat restoration projects on the most important actions for recovering salmon and steelhead. The top priority actions have centered on reconnecting and restoring floodplains and reconnecting side-channel and off-channel habitat. The region also is completing projects that address fish passage barriers and improve water quality.
Other important work has been restoring riparian areas in forests. Riparian areas are shorelines, streambanks, wetlands, and floodplains next to bodies of water that support and protect the health of the water. Riparian forests help shade the water, cooling it for fish. The trees drop branches and leaves into the water, which provide food for the insects salmon eat and places for salmon to rest and hide from predators. The tree roots keep soil from entering the water and burying spawning gravel.
