chum

Need to know more about populations and habitat factors contributing to huge decline. biology and limiting factors are unknown and should be first step to recovery.

comprehensive study that links park with downstream (70% outside of park)

Chum population was unique and huge and should be recovered

no data on juvenile crescenti; no data on beardslee

Ensure water quality

Bibi index of stream health was low in both upper and lower reaches. Reasons are unclear.

Protection of logjam at powerline

Retention of log jam crucial to crescenti spawning gravel

Throughout watershed but especially in lower reaches

spawning and rearing

increase habitat and catch gravel

Addition of large woody debris. Mainstem jams must be large and channel spanning, and form beads on a string, to capture wood and spawning gravel. Jams can be smaller on higher tribs, to reduce peak flows.

Legacy of forestry practices has left insufficient riparian buffer for input of large woody debris. Must be accompanied by riparian restoration, but riparian restoration alone will take too much time.

Throughout watershed

spawning and rearing

Protect riparian corridors to prevent additional damage to watershed hydrology processes and salmonid habitats.

Acquisition of slopes, 500 foot river corridors, fluvial landscape, and all of the floodplains will ensure corridor stability, riparian refugia, cool stream temperature, and protect water quality and velocity.

Current forestry practices and buffers are not sufficient to prevent changes to river hydrology and damage to salmonid habitat. Helicopter logging would reduce roads and some sedimentation but remaining riparian corridor will still be insufficient for providing necessary refugia for shade, large woody debris, and stability.

Acquire available forestry properties, retain crucial riparian strips, and sell remainder with proceeds to be used to purchase additional properties.
