During the summers of 1965 and 1966 a study was made on the history and status of several exotic big game, now present in northwestern San Luis Obispo County, California. Zebra (Equus burchellii), fallow deer (Dama dama), sambar (Cervus unicolor), elk (Cervus canadensis nelsoni), thar (Hemitragus jemiaicus), and aoudads (Ammotragus leryia) are now present having escaped in 1953 from the zoo owned by William Randolph Hearst. Sambar, elk, thar and aoudads have all been seen up to ten miles from the release site, but the majority of these animal remain within four miles of Hearst Castle. Information on the ecology of these introductions is needed.
