Wild bison on Catalina, a species introduced to the island in the 1920's, believed to have been done for a movie shoot, which never actually used any shots of bison on the island. The herd's population is now regulated by a birth control program designed to keep their numbers around 150 to reduce island impacts, by the Catalina Island Conservancy.
