Better late than never. The best example of a native run rebounding is the Nooksack river.
It by far has the best return year after year. Granted the earlier, Dec, till mid January run componit, is basclicly gone. This river went from the worst run in the early 80's in puget sound, to now what is very good. The Nooksack has been cnr since the 80's and I can tell you that it is one of the best. Trout unlimited vollentiers for the past three years have been doing stream surveys in spring for spawning fish and are just now getting a handle on what really is going on.
I think that is one example that has not been included in any thinking. I beleive it really does make a difference and the nooksack is a prime example. I am sure I will get a lot of greif about this post from the Bellingham boy's, now that the cat is out of the bag.
