A recent aerial survey revealed there are only three wild caribou left in the contiguous United States. Biologists say the chances to save them are slim, but an international recovery team is still trying.
Before the 19th century, thousands of woodland caribou ranged from Washington to New England. But then those herds were decimated by overhunting, logging and broken-up habitat.
Now you can count the number of wild caribou left in the Lower 48 on one hand. They live in the Selkirk Mountains of northern Idaho.
