After being wiped out for several decades, the wolf was reintroduced into the Idaho area in 1995.  Reports from the U.S. Fish and Wildlife Service have estimated there to be about 285 wolves in Idaho presently.  Since the reintroduction, the wolves have migrated as far as Utah and Oregon.

Wolf organizations have been very involved in protecting the wolves in Idaho.  They have in the past offered rewards to aid in the apprehending of people who were responsible for poisoning the wolves in this area.
In April of 2003, Idaho's Federal District Court judge, Julie B. Winmill, renewed a protection plan for wolves in the Sawtooth National Recreation Area.  This decision will also protect wolves on private lands within the Sawtooth National Recreation Area.
