POPULATION TREND: Gray wolf populations were eliminated from Montana, Idaho, and Wyoming by the 1930s. Thanks to federal protection, they began to successfully recolonize northwest Montana in the early 1980s. By the end of 2010, estimates of wolf numbers were 739 wolves in the Central Idaho Recovery Area, 501 in the Greater Yellowstone Recovery Area, and 374 in the Northwest Montana Recovery Area, for a total minimum estimate of 1,614 wolves in the three recovery areas.
