Dan Porter: Well salmon and big trees go hand in hand, and have for some time.

Mill Creek is a refugium for coho salmon

Its a creek that is absolutely critical for the recover of salmon

Narrator: Instream restoration efforts ar intended to restore the processes that create healthy salmon habitats

Over 20 years of fisheries monitoring in Mill Creek has shown that fish numbers in the West Branch are much higher than fish numbers in the East Fork
[downstream monitoring photos
This difference is partly due to the lack of wood in the East Fork, and to the predominance of alder trees

"Well after 100 years or more of commercial wood extraction, the streams and rivers here have become so depleted of wood that their form has become counter-productive to salmon habitat and to the habitat forming processes that are related to wood.
In order to restore these habitat forming processes, it is necessary add a lot of wood
we've got forest restoration, hillslope restoration where we are removing old logging roads

"Our objective to restore process requires us to reintroduce vast amounts of wood that was similar to what was here over geomorphic time"

But salmon don't live in geomorphic time, salmon live in BIOLOGIC time

"We're taking the steps to make that time occur over maybe a 25-50 year time scale, instead of a 500 to thousand year time scale"
Without wood, forest streams become simplified - often described as "flumes" or "bowling allies"
Rivers with intact riparian zones deliver large volumes of wood to stream channels, creating complexity for fish by influencing the way water and gravel moves downstream
One of the main goals of the instream restoration program at Mill Creek is to build large, complex wood jams.
we constructed this structure to create side channel habitat, and refugia for hi flow migration (paraphrase
This type of instream restoration began at a small scale in the East Fork of Mill Creek, starting in 2006
An additional 10 complex wood jams were constructed in 2008, and we are already seeing profound results.
With time, the East Fork of Mill Creek will provide much better spawning and rearing habitat for the numerous salmon and trout that return to Mill Creek each year.
With continued restoration efforts, Mill Creek will continue to play a critical role as both a forest stronghold, and a salmon stronghold.
