About 700 are believed to live in Michigan's Upper Peninsula.
Supporters of the bill say it's time to allow hunters and trappers to thin the population.
They say wolves are killing livestock and venturing too close to towns.
The Humane Society of the United States has said it may sue to restore federal protections.
Environmental groups and Indian tribes say more time is needed to make sure the population is secure before hunting is permitted.
When the gray wolf was eradicated from Yellowstone National Park in the 1920s, more was lost than just the noble and fascinating predator. The park’s entire ecosystem changed. Now, nearly a dozen years since the wolves returned, the recovery of that system to its natural balance is well underway, say ecologists William Ripple and Robert Beschta of Oregon State University.

Actually one thing they have noticed in areas that have re-introduced wolves is that the areas become very healthy again. Those environments were meant to have wolves, their absence had a profound detrimental effect.
Wolves were believe to be responsible for a dramatic drop in the Southern Alaska Caribou Herd's population, which once numbered up to 10,000 in 1983, only to drop to a population of 600 animals in 2008. Wolf predation was also believed to be responsible for virtually no calves surviving for the two years prior the culling plans, despite a 70% pregnancy rate.
In the former Soviet Union, depending on the locality, a single wolf can consume 90 saiga, 50-80 wild boar or an average of 50 domestic or wild caribou annually. A pack of 2-5 wolves will often kill 2 caribou every three days.
Further reports from the former Soviet Union indicate that rather than prey on exclusively sick or infirm prey, wolves seem to attack young or pregnant animals far more frequently, regardless of their sanitary state. In the Nenetskij National Okrug, wolves were shown to select pregnant female domestic caribou and calves rather than infirm specimens, with some reports showing that wolves bypassed emaciated, sickly animals in favour of well fed ones.
Large numbers of wolves have also been blamed on the decline of critically endangered saiga antelope herds in Central Asia. During the late 1950s and early 1960s when the Soviet Union used poison to effectively bring down wolf numbers, the number, as well as the range of moose, wild boar and red deer increased.
Caspian seals were valued as fur bearers in the Soviet industry, and in a three week period in February 1978, wolves were responsible for the wanton killing of numerous seals on the Caspian sea near Astrakhan. Between 17-40% of the seals in the area were estimated to have been killed, but not eaten
