Endangered Species
Cutthroat Trout
The population is almost gone in some creeks due to exotic parasite Myxobolus cerebralis (causes whirling disease), an invasive species known as the lake trout, and the effects of a continued drought across the intermountain west. 538 cutthroat trout have been counted as they migrated up Clear Creek which is where they are more commonly found in 2007; that was very similar to the count of 489 obtained in 2006, but far below the 917 seen in 2005; 1,438 in 2004; 3,432 in 2003; and 6,613 in 2002.
As of 2011, no endangered animals reside in Yellowstone Park. Although the U.S. Fish and Wildlife Service lists gray wolves as an endangered species, the Yellowstone population is considered experimental and not included in this classification. Gray wolves were reintroduced into Idaho, Montana and Wyoming in the 1990s, and more than 300 individuals now live in and around the park. In its other habitats, the gray wolf is still considered endangered.
