Gray wolf (Canis lupus)
Listing Status: (and others listed below)
The Gray Wolf, being a keystone predator, is an integral component of the ecosystems to which it typically belongs. The wide range of habitats in which wolves can thrive reflects their adaptability as a species, and includes temperate forests, mountains, tundra, taiga, and grasslands. Gray wolves were originally listed as subspecies or as regional populations of subspecies in the contiguous United States and Mexico. In 1978, we reclassifed the gray wolf as an endangered population at the species level (C. lupus) throughout the contiguous United States and Mexico, except for the Minnesota gray wolf population, which was classified as threatened. Gray wolf populations in the Northern Rocky Mountains and Western Great Lakes were delisted due to recovery in 2011 and 2012.
The FWS is currently monitoring the following populations of the Gray wolf

» Life History
Wolves are habitat generalists and lived thorughout the northern hemisphere. They only require ungulate prey and human-casued mortality rates that are not excessive.
Ungulates [wild and domestic] are the typical prey of wolves, but wolves also readily scavenge. Beaver are among the smallest important prey but wolves can utilize smaller mamals, birds, and fish.
Movement / Home Range
Wolves packs defend their territories from other wolves. Territory size is a function of prey density and can range from 25-1,500 square miles. Both male and female wolves disperse at equal rates and equal distances, sometimes >600 miles.
Normally first breed as yearings and once a year in February. One to 10 pups [normally ~5] are born 63 days later. Pups normally stay with pack until > 1 year old.
