Wolves

Gray wolves, also known as //canis lupus// are needed very much in their ecosystem. Take the example of when wolves in Yellowstone were hunted until there were none left in Yellowstone. Because of that, the elk over populated and ate all the plants, then there were no trees to keep the river from eroding, beavers stopped coming because there were trees that they liked to use for their dam, then there were no fish because the river was unhealthy, then no raptors came because there were no fish. But in the end wolves were brought back to Yellowstone. Wolves only live in Canada and Eurasia, though, wolves are protected in Yellowstone, all of Oregon(or they were), and California. They used to be unprotected in California, until an amazing wolf named OR-7 wondered into California. by: Kira Royce
