It's much more than that even. Without the wolves the elk and deer graze along creeks destroying willows that shade the water leading to warmer water temps and fewer fish, more erosion and less water retention / flood control. This even impacts downstream farmers who take water out for irrigation.

Also the wolves keep mountain lions, coyotes and other predators in check (through competition and even predation) and wary. I suspect mountain lion encounters in California will go way down if the wolves ever come back.
