Rewilding: Reintroducing Wild Wood Bison to Alaska
After more than 100 years of absence from the United States, a wild population of North America’s largest land mammal may soon be reintroduced to Alaska: wood bison. Larger than plains bison (Bison bison bison)—which may weigh up to 1,900 pounds—wood bison (Bison bison athabascae) bulls tip the scale at up to 2,250 pounds.
