Health and Human Safety
April 12, 2013 – Gray wolf populations were extirpated from the western United Stated by the 1930s. Public attitudes towards predators changed and wolves received legal protection with the passage of the Endangered Species Act (ESA) in 1973. Subsequently, wolves from Canada occasionally dispersed south and successfully began recolonizing northwest Montana (MT) in 1986. In 1995 and 1996, 66 wolves from southwestern Canada were reintroduced into Yellowstone National Park (YNP) (n=31) and central Idaho (ID) (n =35). Recovery goals of an equitably distributed wolf population containing at least 300 wolves and 30 breeding pairs in 3 recovery areas within MT, ID, and Wyoming (WY) for at least 3 consecutive years were reached in 2002. By 2012, the entire Northern Rocky Mountain Distinct Population Segment (NRM DPS) was delisted and wolves were managed under State authority in MT, ID, WY, eastern one-third of Washington (WA) and Oregon (OR), and a small part of north central Utah (UT). Based on minimum population counts, the 2012 NRM DPS wolf population contained >1,674 wolves in >321 packs with >103 breeding pairs (MT >625wolves in >147 packs with >37 breeding pairs; ID >683 in >117 packs with >35 breeding pairs; WY >277 wolves in >43 packs with >21 breeding pairs; WA >43 wolves in >7 packs with >4 breeding pairs; and OR >46 wolves in >7 packs with >6 breeding pairs). No packs were documented in Utah (UT).

May 2011 - The Service published a direct final rule delisting wolves in Idaho, Montana and parts of Oregon, Washington and Utah. This final rule implements legislative language included in the Fiscal Year 2011 appropriations bill. The Service and the states will monitor wolf populations in the Northern Rocky Mountain DPS and gather population data for at least five years.
