Corrugated fiberboard is sometimes called corrugated cardboard, although cardboard might be any heavy paper-pulp based board.
Gray Wolf. The gray or timber wolf's story is one of the most compelling tales of American wildlife. Once, the wolf was widespread across most of North America, but it was hunted ruthlessly and extirpated over most of its range. Today, the wolf is making a successful comeback in some of its former habitat due to strong conservation efforts.
Then in 1995 and 1996 the U.S. Fish and Wildlife Service reintroduced two populations of wolves, one in central Idaho, and the other in Yellowstone National Park, Wyoming. Gray wolf populations have since expanded rapidly.
