“The wolves are back”“…and this is why the caribou and the wolf are one; for the caribou feeds the wolf, but it is the wolf that keeps the caribou strong” – Farley Mowat. This quote is a great example of wolves maintaining balance in nature and collaboration between two different animals. The gray wolf was reintroduced to Yellowstone in 1995. They were reintroduced by the government due to the endangerment of their species. The reintroduction of the gray wolf was beneficial because it improved the Yellowstone ecosystem, protected the wolves, and attracted tourists. The reintroduction of the wolf to Yellowstone National Park has greatly improved the park's ecosystem! An example of this can be found in the article “In the Valley of Wolves,” which states “Now, nearly a dozen years after the wolves' return, the restoration of that same system to its natural balance is well underway, ecologists say William Ripple and Robert Bescheta of Oregon State University” (“In the Valley”). The article explains that the ecosystem has begun to recover and continues to recover due to the reintroduction of the wolf. Another example is from “In the Valley of Wolves,” “…wolves affect elk; elk strike aspen; and then the wolves strike the aspen” (In the valley”). In other words, if there weren't wolves eating elk, there would be more elk eating aspen, and aspen is a huge factor in the Yellowstone ecosystem. Without the gray wolf, the Yellowstone ecosystem might function, but not to the best of its ability. By comparison, wolves had been missing from Yellowstone for more than 70 years. As they left, the ecosystem continued to function properly. With the return of the gray wolf, the ecosystem has improved. Yellowstone depends on the gray wolf for help... middle of paper... ts. “Wolves are very resourceful. All they need to survive is for people not to shoot them” – Bob Ferris. This is true; we are the ones who extinguished them, so it is our job to fix it. Works cited. Guns, Karen. Point of view: “Where should wolves roam?” Environmental Science.Austin, 2008.
