You know it was prevailing science that said all woody debris out of the stream. That DOE said carcasses pollute the stream, the list is huge as too things science says especially from folks with a axe to grid. As to OP habitat being pour, from what starting point? If it is completely natural state, not yes but hell yes! If not that then compared to the rest of the coast? State ? Harvest has driven salmon stocks down time and time again but it is a response to our own vested interest in the system that stops real change.

The concept that we going to have enough money to fix degraded habitat is a dream. That we can stop further destruction of viable watersheds, yes but not likely in the near term. That harvest, especially ocean intercept fisheries, will be reduced and a ecosystem harvest approach stream by stream implemented? Doubt it so on we go with the totally irrational approach to Salmon that has existed my life time.

As to the Elwha a lot is riding on this experiment and I really doubt that the folks and tribes in that area give a wiz what a bunch of PS advocates think. The tribes will approach the Elwha restoration from a point of self interest political reality. Nothing all that unusual in that approach.
