The endangered key deer, or Odocoileus virginianus clavium, makes its home only in the Florida Keys. While deer seem to be prolific in the Southeast, this particular subspecies has been nearly driven to extinction by overhunting, habitat loss, illegal feeding and cars.
In fact, by the early 1950s, only 50 key deer were still alive. Conservation efforts have helped restore the key deer to around 1,000 animals. Today, the deer remain threatened primarily by continued habitat encroachment and vehicular hits.
