An interesting feature of the endangered species list in the Wildlife Act is the inclusion of the barren ground caribou. This animal is actually not endangered but gets on the list because it looks like the Woodland Caribou, a truly endangered species.
Look-alike species crop up in lists all over the world. They have proven to be an effective enforcement tool. For example, with legislative protection given to both caribou species, no one can claim: "I thought it was a barren ground caribou, so I figured it was OK to shoot it."
