    They did such a good job that, by 1926, no gray wolf packs were left in the park. Over the following decades, virtually every other part of the park's ecosystem was affected by the loss of the wolves --- from the animals who were their prey, to the plants that were the food for that prey, to the streams that were sheltered by those plants --- and the landscape was in distress.
