Yellowstone Lake below biological potential due to lake trout infestation
Despite a yearly effort that kills thousands of the big non-native trout, a much more aggressive effort is needed. This costs money, but the biological dividend would be huge because the beleaguered Yellowstone cutthroat trout, which are being eaten by the lake trout, are the prey for dozens of mammal and avian species as well as stream anglers upstream outside the the Park in Wyoming. Lake trout provide no food for Park animals at all because they live in deep water. Nothing eats them except a few human anglers. Meanwhile the lake trout wipe out (eat) the valuable Yellowstone cutthroat that live in and spawn in shallower waters.
