Around 1924 a small number of bison were released on Santa Catalina Island, one of four relatively large islands of the Channel Islands Archipelago located about 20 miles offshore of Los Angeles, California. Bison are not native to any part of California and are therefore an introduced exotic species on Santa Catalina Island.

Although bison are considered a keystone species in their native range, on this isolated offshore Island they play a different role. This study revealed more about the population ecology and health of bison on Santa Catalina Island and how their activities effect Island plants and animals.
