The Endangered Species Act,was passed in 1973, and one year later, the gray wolf is listed as endangered; and thus recovery was mandated under said Act. The gray wolf was present in Yellowstone when the park was established in 1872 and the last wolf pack in Yellowstone is killed in 1926, although reports of single wolves continue. In June 1994, after several years and a near-record number of public comments, the Secretary of the Interior approved reintroduction of gray wolves to Yellowstone and central Idaho. On January 12, 1995, Canadian wolves were reintroduced to Yellowstone National Park, which is the world's oldest national park, after decades of likely absence, followed by subsequent reintroduction of a handful of wolves at set intervals within a year after the fact. The reason for said introduction was to restore balance to the ecosystem and improve biodiversity, namely to thin out herds of elk and bison which grazed on other endangered species like willow and aspen, induced erosion by trampling on vegetation that held the soil in place, and were more likely to succumb to infectious diseases when faced with starvation.
