Status of moose in the contiguous United States

Moose have expanded their range in the northern tier of the United States and along the Rocky Mountains in Utah and Wyoming over the past several decades. The expansion has been occurring since the 1940's, but has apparently accelerated in recent decades. Introductions in Colorado, Idaho, Michigan, and Utah have been successful as well. Reasons for the expansion include habitat change favoring moose and reduction in exploitation. Uncontrolled exploitation, including harvest by native Americans, poaching, and unintended take as through vehicle accidents may limit populations in some areas. Records on population size and harvest are provided for the states that monitor and hunt this species.
