The SPIRIT BEAR, or Kermode Bear, is one of the most famous, and unusual, denizens of the Great Bear Rainforest.   It is actually a member of the black bear family, but a recessive gene gives it its white color.  The Spirit Bear's parents and siblings are usually black; the white bears occur in about 1 out of every 10 births.   British Columbia's north coast is the only part of the world where these bears are found.  The largest concentrations of Spirit Bears are on Princess Royal and adjacent islands, and in some nearby mainland valleys.   This area is now the focus of a major campaign aimed at creating a sanctuary for the Spirit Bear that would protect its habitat from the threat of proposed logging.
