well the point is, even where there are mountain lions and wolves, they don't predate on otters much so it's not that those are gone.
The otters have been back in the park for twenty years. they probably have reached their equilibrium level at this point. They are present on pretty much every stream in the park at this point. The fish are still there. Most streams still contain over 1000 trout per river mile.
